Description
TITLE OF THE INVENTION
Tactical Law Enforcement System
CROSS-REFERENCE TO RELATED APPLICATIONS
[001] This application claims priority to U.S. Provisional Patent Application Ser. No. 62/378,329 entitled "Link-HQ (Tactical Smart System w/ Smart Holster)," filed August 23, 2016, which is incorporated by reference.
BACKGROUND OF THE INVENTION
[002] The present invention is directed to a law enforcement surveillance system, and more particularly one that features multiple technical components including smart glasses, smart holster, and data linkage.
[003] Over the last few years, body -worn cameras have become a critical tool in effective law enforcement. According to a 2014 U.S. Department of Justice report, incorporated here by reference, body cameras increase the performance of law enforcement personnel, as well as the conduct and participation of community members engaged by law enforcement
(https://www.justice.gov/iso/opa/resources/472014912134715246869.pdf).
[004] Law enforcement agencies using body cameras report the following benefits: improved evidence collection; strengthened officer performance and accountability; enhanced agency transparency; improved means to document encounters between law enforcement personnel and the public; and, improved mechanism of investigating and resolving complaints and officer-involved incidents.
[005] Transparency in operations prevent both internal and community based problems from arising in the first place. Increased officer professionalism and performance can be
accomplished through internal review of body camera data, and outside access to such data through legal and responsible means can improve public relations and help identify structural problems of law enforcement agencies.
[006] To illustrate, one study of a California police force found that body camera deployment resulted in 88% fewer complains against officers, and a 60% reduction in officer use of force incidents. Another study reviewed in the Department of Justice report, this one involving an Arizona police force, measured 40% fewer complaints and a 75% reduction in officer use of force incidents.
[007] According to a 2016 report by the Johns Hopkins University Applied Physics Laboratory, incorporated here by reference, over 60 different body cameras have been produced specifically for law enforcement use (Hung, Vivian et al. A Market Survey on Body Worn Camera Technologies). The systems were qualified as having at least one camera, internal data storage, compatibility for software analysis, and typically located on the body or head.
BRIEF SUMMARY OF THE INVENTION
[008] In a preferred embodiment of the present invention, a system for law enforcement system for protection and surveillance is presented, said system featuring a communicable smart, or data-enhanced, holster for communicating to other law enforcement personnel a gun draw incident, and smart, or data-enhanced, glasses for recording events and incidents of special concern.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING
[009] The present invention will be better understood from the following detailed description with reference to the following drawings:
[010] FIG. 1 A is a perspective view of the eyewear component of the surveillance system in its open, active recording conformation.
[Oi l] FIG. IB is a perspective view of the eyewear component of the surveillance system in its closed, off-line conformation.
[012] FIG. 2 is a side view of the holster component of the surveillance system with docked pistol.
[013] FIG. 3 is a side view of the electronic component of the surveillance system isolated from the holster for further consideration.
DETAILED DESCRIPTION OF THE INVENTION
[014] The unique attributes of the tactical law enforcement system are presented in detailed embodiments below. Chiefly, the system in its realized or anticipated embodiments the system measures the withdrawal of a gun from a holster and immediately triggers recording capabilities and alerts to backup law enforcement personnel. The embodiments below are presented as designed or tested illustrations only, and are not meant to limit the system from extension to alternative, similar embodiments.
[015] In an exemplary embodiment, shown in FIGS. 1 through 3, a novel surveillance system is presented. The performance and safety benefits of the surveillance system are accomplished by introducing electronics into a gun holster, thereby allowing the holster to register the removal of a gun, and to both automate the audio and video recording of events immediately thereafter as well as notify a monitoring command response organization or team.
[016] The present technology consists of a law enforcement surveillance and
communication system that is an advancement over current law enforcement point-of- engagement surveillance technologies, commonly referred to as body-warn camera systems. The
present system may be considered "smart" technology in that it utilizes sensors and automation, and may develop, process, and share data.
[017] The present technology is designed for law enforcement personnel, generally, and for tactical groups such as those involved in rescue and anti -terrorism missions.
[018] In FIG. 1, a smart hostler unit is presented. The holster 10 is designed to fit a standard law enforcement or military grade pistol, or custom molded to a particular gun model 20. The holster 10 may be made from one or a combination of casing or shell materials rubber, polymer, leather, or metal, as customary in the holster industry. Within the holster casing is a collection of electronics and sensors 30.
[019] The electronic componentry 30 consists of magnetic contacts 40A, 40B, 40C, an electromagnetic switch 50, a signal transfer from the magnetic contact sensors 55 to a central micro-chip processor 70 housed upon a circuit board 60, a processor input for the associated system eyewear 80, a gyroscope mount and camera combination 90 connected by signal transfer to the central processor 95, and a lithium battery 100.
[020] Within the holster, the magnetic contacts 40A, 40B, 40C are staggered and arranged around a pistol barrel such that when a pistol is docked or secured within the holster, one contact 40A extends to the muzzle, another contact extends nearly to the muzzle 40B, and a third contact 40C terminates above the second contact and along the lower midpoint of the barrel between trigger and muzzle. The contacts may consist of small, circular .51b holding power 12 or 24 VAC magnets, depending upon the size of the holster.
[021] The contacts connect by individual leads to a mini push-pull electromagnetic switch 50, located above the contacts and closer to the mid-point of the barrel of the docked pistol. The switch 50 abuts and is connected to a circuit board 60 housing a microprocessor 70
with multi-purpose flash technology for processing and storage of audio, video, gyroscope, and Global Positioning System (GPS) data streams.
[022] Extending from the circuit board 70 out into a forward facing housing of the holster is a miniature camera mount gyro scope and video camera 90, such as a Y2000 Mini Micro HDPC 720p model.
[023] When a pistol 20 is removed from its holster such that two of the three magnetic contact points 40A, 40B have been broken, a signal change in the form of a color change will occur. The .51bs magnets encircling a docked pistol provide a total of 1.51bs of applied force when the pistol is housed within the holster. When the pistol is docked within the holster and in contact with three magnets, a small 40/20 milliamp signal will activate a green light on the small circuit board 60 housing the microprocessor 70. When two of three magnetic contact points are broken by the removal of a docked pistol, the indicator light will change from green to red.
[024] When the red light indicator is activated, the electromagnetic switch will turn on the holster camera 90 and record until the green light indicator returns. Once green, the camera will record for an additional three minutes before shutting off.
[025] Each smart holster system is assigned a reference number or IP address for remote tracking and communication via GPS or Global System for Mobile Communications (GSM) satellite positioning technology. The holster's microprocessor 70 monitors a red/green light source on the circuit board 60 and actively sends a red/green signal along with the current global position of the holster and its wearer to an outside monitor, such as a central command unit.
[026] When a pistol is holstered or docked, a central command unit or corresponding monitor will recognize the pistol carrying person or agent as a green light; when two of three contacts 40A, 40B are broken, the central command will see the agent as a red light and respond
accordingly, for example with backup support deployed to assist the agent who has withdrawn his or her pistol.
[027] FIG. 2 presents an exploded view of the electronics componentry of the holster isolated from the holster for the Examiner's benefit.
[028] FIGS. 3A and 3B present perspective views of the surveillance eyeglasses in open 3 A and closed 3B conformations. In the open 3 A position, a centerpiece 110 provides a housing for a camera 112 that is activated, or turned on for recording, when the frames 120 A, 120B are extended outwards to wrap the wearer's ears 122 A, 122B. The glasses additionally feature an earpiece 130 allowing communications to be heard from fellow law enforcement personnel, charging 140A, 140B and internal electronics components 142A, 142B, a microphone 150 for recording encounters and events, a flashlight for night use 160, a charging port 170, wireless linkage 180, an SID card 190, and a male adaptor 200 for plugging into the holster 10.
[029] When the surveillance glasses are opened, the camera 112 and microphone 150 are activated to enable recording or any particular circumstance or event. The information generated is stored short term on a SID card 190 for later access.
[030] An example of use would involve a law enforcement agent's suspicion of a criminal activity or dangerous encounter. The agent would then remove the eyeglasses from their closed 3B or charging conformation to begin recording. Alternatively, the agent could wear the eyeglasses throughout a patrol or working shift, taking advantage of the earpiece 130
communication potential and any special endowments of the eyeglass lenses, such as zoom perspective or night-vision artificial sight.
[031] The eyeglasses are connected by tethered male adaptor to a receiver port on the holster, allowing data transfer from glasses to processor.
