Description

DIGITAL PHOTO FRAME WITH WEATHER FORECASTING ABILITY

BACKGROUND OF THE INVENTION

1. Field of the Invention The present invention relates generally to electronic photo display devices and more specifically it relates to a digital photo frame with weather forecasting ability which displays images and other data (including climate data, weather forecast, time, and a calendar), on an LCD display. The digital photo frame with weather forecasting ability also generates soothing sound and lighting effects, and incorporates both an AM/FM radio and MP3 player.

2. Description of Related Art

A variety of devices and methods are known in the art for displaying digital photos. Of such devices, many are directed to dedicated frames for showing user loaded images. It can be appreciated that digital photo frames have been in use for a long time. With advances in technology come new concepts, and the digital photo frame with weather forecasting ability is one such concept. Typically, digital photo frame type devices are composed of an LCD display and integral electronics which process and hold digital photographs normally captured by a digital camera.

Digital photo frame devices in the prior art described below, like most electronic devices, use some memory devices, internal or external. Some have an interface to load user data into the unit, and some work wϊrelessly to load images. See U.S. Pat No. 5,365,686, U.S. Pat No. 4,754,271, U.S. Pat. No. 5,504,836, U.S. Pat. No. 6,975,308 Bl, U.S. Pat No. 7,107,605 B2, U.S. Pat. No. 6,535,139 Bl₅ U.S. Pat. No. 6,266,069 Bl, U.S. Pat No. 6,396,472 Bl, U.S. Pat. No. 5,359,374, and U.S. Pat. No. 4,748,756.

Weather Station devices tend to be large complex affairs designed to be fixed to one location, see U.S. Pat. No. 4,287,762 as one typical example. Only a few examples of small units exist, such as U.S. Patent Application Publication No. 2006/0095210 Al and U.S. Pat. No. 7,088,221 B2, both of which deal only with presentation of messages or animations, and both of which are designed to be fixed in one location. LCD display technology is well known and is detailed adequately in U.S. Pat. No. 4,560,982 and U.S. Pat. No. 4,591,849 respectively.

The main problem with the conventional digital photo frames in the prior art so noted above, is that traditional designs only allow for static image display with little regard for other integrated functions while weather stations are designed for use in one fixed location. Although some designs have included touch screens, have monitored light and sound levels near the unit, and have used these as inputs to change photos, none of these designs go past the concept that an LCD display can be used for more than decorative purposes alone. None of the conventional devices have any incorporated weather prediction function. None of the conventional devices can be used dynamically on the move and are clearly statically fixed to one location. None of the devices so mentioned above shows the ability to play soothing sounds, or posses an AM/FM radio or MP3 player.

Moreover, none of the conventional devices have the ability to monitor weather conditions and automatically play soothing sounds or generate lighting effects to enhance the user's environment during adverse weather situations. Moreover, none of the known weather stations monitor weather conditions and automatically play soothing sounds to help a user sleep soundly through a thunder storm or activate a light to simulate a rising sun on a cloudy day, for example. None of the known devices have the ability for the user to manually elect which particular soothing sound or lighting effect should be used during forecast weather events, or to allow a user to upload his/her own images and sounds in lieu of default options.

These early digital photo frame devices generally have been considered satisfactory for their intended purpose. However, there still remains a continued need in the art for increased functionality. There also remains a need in the art for a more functional digital photo frame that is inexpensive and easy to make and use. The present invention provides a solution for these problems.

Figs. 3a-3e and 3g show digital photo frame 200 in the closed configuration. The closed configuration is compact and is well suited for storage in a pocket, purse, or other suitable storage arrangement. As best seen in Figs. 3c and 3d, screen 204 is visible even when housing 202 is in the closed configuration. Housing 202 can be opened into the self- standing configuration shown in Fig. 3 f when it is desired to display digital photo frame 200, for example on a desk, table, dresser, or any other suitable flat surface. Figs. 4b, 4c, and 4d show side views of housing 202 in closed, intermediate and opened configurations, respectively. Those skilled in the art will appreciate that the ability to change from a closed to an open configuration is an optional feature. However, the ability to convert from a compact closed configuration to an opened, self-standing configuration can be particularly useful, for example, when traveling.

Figs. 3h and 3i show the back of housing 202 where batteries 210 can be accessed by removing batter cover 212. Fig. 4h shows cover 212 separated from housing 202. Those skilled in the art will readily appreciate that any suitable type of batteries can be used, including rechargeable or disposable cells, without departing from the spirit and scope of the invention. Similarly, while cover 212 is shown attached to housing 202 with by means of a screw, those skilled in the art will readily appreciate that a snap on cover, or any other suitable type of cover can be used without departing from the spirit and scope of the invention. Moreover, cover 212 is an optional feature if rechargeable or long life batteries are used.

While batteries 210 have been described in conjunction with providing power to digital photo frame 200, the power source for digital photo frame 200 can be a solar panel, DC adaptor, dynamo, or any other suitable power source without departing from the spirit and scope of the invention. Therefore, the use of button cells in the illustrations is not limiting and is for illustration only.

Fig. 3f shows that when housing 202 is in the opened configuration, USB interface 214 is exposed. Fig. 4e shows USB connector 216 plugged into USB interface 214 in housing 202. USB connector 216 allows for convenient data transfer between digital photo frame 200 and an external data source, such as a personal computer. Those skilled in the art will readily appreciate that Firewire, serial connector, other standard interfaces, or any other suitable data connector can be used without departing from the spirit and scope of the invention. Moreover, it is also contemplated that other types of interface such as one or more wireless interfaces (e.g., Bluetooth®, Wi-Fi®, and other suitable wireless interfaces) can be used in addition to or in lieu of a USB type interface.

As depicted in the exploded view of Fig. 5, and in further accordance with the invention, a printed circuit board (PCB) 220 is provided within housing 202. USB interface 214, display 204, keypad 206, and batteries 210 are each operably connected to PCB 220. An integral climate measurement sensor 218 is provided on PCB 220 for sensing ambient conditions including pressure, temperature, humidity, UV index, altitude, and any other suitable conditions. Sensor 218 can be attached directly to PCB 220 as shown in Fig. 5. It is also possible to locate sensor 218 in other portions of housing 202 as long as sensor 218 can operate to sense ambient conditions. PCB 220 uses sensor 218 to collect data on ambient conditions. PCB 220 processes this data into weather information, including current conditions and forecasts, which can all be shown on display 204. Integral in this context means integral to the function of the unit. Those skilled in the art will readily appreciate that use of external sensors not physically connected onto the housing but remote and electrically connected by wire or wirelessly to the housing is possible without departing from the spirit and scope of the invention.

Memory can also be associated with PCB 220, as is known in the art, for storing data such as digital photographs, calendar data, address book data, digital music, and any other suitable type of data. A user can use keypad 206 to order PCB 220 to display photographs, weather information, calendar information, address book information, alarm clock information, soothing light patterns, and any other kind of data on display 204. Moreover, PCB 220 can include components for an AM/FM radio and/or MP3 player. The discussion of the MP 3 Standard in this description is not limiting, and those skilled in the art will appreciate that the use of other audio recording standards are well within the spirit and scope of the invention.

Moreover, for clarity of the drawings, no earphones or speakers are shown in the diagrams. However, those skilled in the art will recognize the use of earphones and/or speakers are well within the scope of the invention.

PCB 220 also preferably includes a clock with an alarm. In order to manage digital photographs, digital music, and other data in the memory of PCB 220, a computer program is provided for an external computer. Those skilled in the art will recognize that any suitable program running on Windows ®, Linux ® , OsX, or any other suitable operating system with or without drivers, can be used in conjunction with USB connector 216 and a personal computer, without departing from the spirit and scope of the invention. PCB 220 contains the electronic components that include digital integrated devices including memory and a microprocessor. The microprocessor collects data from keypad 206, samples data from the integral climate measurement sensors 218, samples data from an external wireless outdoor weather sensor module (e.g., module 332 described below), performs calculations and displays the results on LCD display 204. It is also responsible for image manipulation, AM/FM radio function, MP3 audio file playing and other functions so described. Those skilled in the art will readily appreciate that PCB 220 can be populated with analogue, digital, discrete components and/or be integrated in multi-chip modules or custom integrated chips and can be composed of any substrate material without departing from the spirit and scope of the invention.

Figs. 6a-8 show another embodiment of a digital photo frame in accordance with the present invention. Digital photo frame 300 is configured for use as a self-standing unit, with dedicated support stand 330 holding up housing 302, which frames an LCD display 304. The functions of digital photo frame 300 are essentially the same as those of frame 200 described above, in which a user can control the various functions via keypads 306, which are on either side of housing 302.

However, in addition to or in lieu of integral climate measurement sensor 218, digital photo frame 300 includes a wireless receiver configured to receive data from an external wireless outdoor weather sensor module 332 (shown in Fig. 7d), Sensor module 332 senses and transmits climate data from outdoors to digital photo frame 300, which is typically used indoors. Normally external wireless outdoor weather sensor module 332 is intended to be used with the desktop embodiment, however this is not limiting and use of an external wireless outdoor weather sensor module with a pocket sized digital photo frame with integral weather forecasting ability (e.g. digital photo frame 200) is a contemplated variation within the scope of the present invention, as will be appreciated by those skilled in the art. Those skilled in the art will readily appreciate that a hardwired version of outdoor weather sensor can also be used without departing from the spirit and scope of the invention. As shown in Fig. 8, digital photo frame 300 includes integral climate measurement sensors 318 (optionally used in conjunction with or in lieu of external wireless sensor module 332), an optional interface (like USB interface 214 described above, and/or suitable wireless interface as suggested by reference character 314, but not shown for sake of clarity), PCB 320, and power source 340., which operate much as described above with respect to digital photo frames 100 and 200.

While the digital photo frame with weather forecasting ability has been described above in the context of a pocket-sized device (e.g. 100, 200) or as a desktop sized unit (e.g. 300), it is contemplated that other suitable embodiments can also be practiced. Those skilled in the art will readily appreciate how to practice the invention as a wall mounted unit or as a car/boat dash board/instrument panel mounted unit, with the same or similar functionality without departing from the spirit and scope of the invention.

In operation, a digital photo frame with weather forecasting ability is preferably configured so as to operate as follows. The user first presses an unlock button on the keypad (e.g. keypad 206, 306) as indicated in Figs 1 through 7, which activates the digital photo frame with weather forecasting ability (e.g. digital photo frame 200, 300) for user interaction. The lock function automatically re-engages after a predetermined time if no input is received. When the digital photo frame with weather forecasting ability is first unlocked, the current temperature, time, alarm status, relative humidity and barometric pressure readings are displayed on the LCD display (e.g. display 204, 304). In this embodiment example, the user then has several menu options, which generally are user mode related and setup mode. In user mode the user can select from several menu options, for example, whether to listen to the AM/FM radio, listen to MP 3 audio tracks, display images on the LCD display, listen to soothing sound or select soothing light effects, scroll thought telephone address book and calendar functions, or select setup. The digital photo frame can be configured to allow the user to set up soothing sound effects to be used to signal a given weather condition or prediction. Moreover, it is possible to allow the user to chose images to display for given weather data in lieu of default images or representations. If the user chooses setup mode, then the weather indicator blinks to indicate that the user should set the weather status by scrolling through the options using the keypad. After setting the initial weather status, the digital photo frame with weather forecasting ability will accumulate weather trend data for a specific period of time before it will begin to forecast the weather. After this point, pressing a button on the keypad will result in data being displayed on the LCD display for a specified period of time.

When travelling and upon arrival at a new location after air travel the user can reset the digital photo frame with weather forecasting ability and select a new location. The digital photo frame with weather forecasting ability will then begin sampling data at the new location and after a specific period of time will start to predict the weather. The user has a further option of selecting the nearest major city, and based upon this selection the microprocessor will compensate for known local weather behaviour from the internal database if appropriate. It is known that in some areas weather is less sensitive to barometric pressure changes than others. A complete database is stored on a disk, for example, supplied with the digital photo frame with weather forecasting ability and the user has the option to load specific weather data using the USB interface (e.g. USB interface 214) and computer software before travel as well as the usual user data such as calendar events, images and telephone address book data.

A setup menu option exists for setting the clock, calendar and alarm functions and need not be detailed here further. The moon phase is displayed automatically once the date is set. The digital photo frame with weather forecasting ability (e.g. 100, 200, 300) includes an altimeter which records the height above sea level of the user dynamically, this can be overwritten by the user should the user have accurate data to recalibrate, otherwise the digital photo frame with weather forecasting ability will calculate this parameter automatically and compensate for barometric pressure change difference by running an averaging algorithm which eliminates outside range erroneous data, as described below.

Two different algorithms will now be described for removing erroneous or outlier barometric readings for weather forecasting. Erroneous or outlier barometric readings can arise from various causes, including but not limited to a change in altitude. The algorithm used depends upon the computational power of the processing unit of the particular device. The first algorithm is a simple averaging algorithm used when a MCU (micro Control unit) does not have the memory or capacity to handle complex algorithms, while the second more complex algorithm is utilized in higher capacity models where greater computational ability exists.

The simple weather forecasting algorithm works as follows. Initially a calibration is performed by Data Sampling the Barometric pressure every 15 minutes for a period of 6 hours. For each hour during this time (that is to say for each 4 samples) an average is taken and is stored as DO, Dl, D2,D3...D24. This is the first sample data cycle. From that point after the initial 6 hours of calibration, the data sample cycle will shift along every 15 minutes. The change in pressure (DELTA P) is then calculated thus: DELTA PO=DI-DO DELTA P1=D2-D1 DELTA P2=D3~D2

DELTA P23-D24-D23. this gives a data trend reference value (X) equal to X- DELTA PO + DELTA Pl + DELTA P2 +....+DELTA P23. Depending on whether calibration is complete, there are two cases:

1. After the first 6 hours of sampling. In the case where the unit has completed its first 6 hours of sampling, if the data trend reference value (X) is in excess of 3 mbar deviation, the weather icon will be changed. The latest pressure reading will be regarded as a valid data point accordingly. 2. Before the first 6 hours of sampling. In the case where the unit has not yet completed its first 6 hours of sampling, if the data trend reference value (X) is in excess of 3 mbar deviation, then the weather icon will be changed and the latest pressure reading value will be regarded as valid.

In both cases, if DELTA P is greater than 2 mbar then the data value will be discarded. Thus there is no difference between the two cases (after initial 6 hours versus before initial 6 hours), except that during the initial 6 hours the twenty four DELTA P values are still being populated and the formula is based on less than twenty four DELTA P values accordingly, whereas after the initial 6 hours, the oldest DELTA P value is replaced with a new DELTA P value and X is calculated based on the new complete set of P1-P24. If a DELTA P is greater than 2 mbar, it is only discarded for purposes of calculating X, but it is still stored in memory for use in computing the next DELTA P.

Once the data trend reference value(X) exceeds 3 mbar deviation, then the weather icon will be changed. If the data trend reference value (X) is positive then a raining icon will be changed to a cloudy icon, a cloudy icon will be changed to a sunny/cloudy icon, a sunny/cloudy icon will be changed to a sunny icon, and a sunny icon will remain sunny. If the data trend reference value (X) is negative then a sunny icon will be changed to sunny/cloudy icon, a sunny/cloudy icon will be changed to a cloudy icon, a cloudy icon will be changed to a raining icon, and a raining icon will remain raining. More advanced weather forecasting algorithms can be employed in units with higher computational ability. A simple moving average algorithm can be formed by calculating the average (mean) value of a series (sometimes referred as period) of barometric measurements (N). The calculation is repeated for each barometric sampling period and the averages are then joined to form a smooth curved line, or moving average. However on its own, simple moving average algorithms are "lagging indicators" and will always be "behind" the real barometric pressure. In general they are trend following indicators. When barometric pressure is trending, then simple moving average algorithms work well, however when the barometric pressure is not trending then a simple moving average algorithm can give misleading results. To get around this limitation and increase the accuracy of the pressure calculation a weighted moving average algorithm is used.

This algorithm is designed to compensate for changes in barometric pressure which result from changes in altitude of the portable unit but at the same time not be subject to a serious lagging effect. To achieve this, a moving average ensemble averaging technique is utilized with low weight applied to outlying values using exponential weights. To achieve this, the algorithm pays less credence to any change in barometric pressure which exceeds 1 mbar in any 60-minute period by applying a very low weight value, the result of which is that the moving average algorithm smoothes out the outlier data but does not totally disregard the value. Normally in order to reduce the lag effect caused by simple moving average algorithms, exponential moving averages (EMA), (often referred to as exponential weighted moving averages) are utilized. These exponential moving averages are described in NIST/S EMATECH e-Handbook of Statistical Methods, http://www.itl.nist.gov/div898/handbook/pmc/section4/pmc431.htm and http://www.itl.nist.gov/div898/handbook/pmc/section3/pmc324.htm (both accessed on July 15, 2008).

The weights applied to the most recent barometric pressure measurements depend upon the specified sampling period of the moving average (N). The degree of weighting decreases as an exponential of a constant smoothing factor called (alpha), which is a number between 0 and 1. Alpha may be expressed in terms of the barometric time sampling period (N), where alpha = 2/(N+l). For example if the period of samples averaged (N) is 19, then alpha would be 0.1. It can be shown that :

EMA(present)=EMA(last sample) + alpha x [(barometric pressure now - EMA (last sample)].

The technique used for trend identification is based on the present barometric reading value. The location of the present barometric reading relative to the moving average can be used to determine the basic trend. If the barometric reading is above the moving average, the trend is considered an upward trend. If the barometric reading is below the moving average, the trend is considered a downward trend. By determining the trend the weather icons can be changed accordingly, as described in conjunction with the more simple algorithm above. Those skilled in the art will readily recognize that the algorithms described above are given by way of example and not limitation, as any suitable moving average algorithm, or any other suitable algorithm in general can be used without departing from the scope of the invention.

The digital photo frame with weather forecasting ability will automatically deactivate the LCD display after not receiving input for a predetermined time in order to conserve power. The unit will resume the current screen when reactivated later.

Another object of the present invention is to provide a digital photo frame with weather forecasting ability with the capability of generating soothing sound and lighting effects.

The digital photo frames described above have weather forecasting ability and also provide for a user to select and display images from memory. As such, the forecasting ability can be used to monitor weather conditions and automatically play soothing sounds and/or display lighting effects. For example, soothing sounds can be automatically played during a thunderstorm to help a user sleep soundly. Another example is on cloudy days, a light or lighting pattern can be automatically displayed to simulate a rising sun. Those skilled in the art will readily appreciate that any other weather condition can trigger other sounds or lighting patterns without departing from the scope of the invention. The digital photo frame can be configured to generate soothing sounds and lighting effects automatically to offset adverse sound or light conditions caused by weather events. It is also possible that this function can be performed according to user input instructions, for example by allowing the user to select which images, lighting patterns, and/or sounds will correspond to a given weather condition or prediction. It is also contemplated that the digital photo frame can be configured to allow the user the option to upload his/her own images and sounds using a computer interface and to give the user the option of using the uploaded data to depict the forecast of particular weather events or offset unpleasant sounds and lighting conditions in lieu of the default options, and/or to choose which uploaded images/sounds to display/play to represent each weather prediction or condition.
