Abstract
<B><MU>CONJUNTO DE CIRCUITO ELETRôNICO RESISTENTE AO CHOQUE<MV><D> Uma unidade de circuito eletrônico resistente a choque (10) é estipulada, na qual um circuito eletrônico está encerrado numa encapsulação (14) que se encaixa em um invólucro circundante (18,22) em contato dispersante de choque. A encapsulação pode ter uma série de extremidades (16,16a,16b), nervuras (24), ou tachões (70) que tocam o invólucro. A encapsulação pode conter um material absorvente de choque (14f) colocado contra o invólucro para proteger o circuito contra trepidações e um material de suporte estrutural (14e) para proteger o circuito contra tensão. A unidade de circuito (10) pode conter um capacitor (34) para armazenar um sinal elétrico e um conjunto de circuitos reguladores para liberação de energia armazenada após uma demora predeterminada. A unidade de circuito (10) pode ser parte de uma unidade de circuito transdutor (55) que contém um módulo transdutor (58), para conversão de energia de onda de choque em energia elétrica para o circuito eletrônico, e a energia liberada pode ser convertida em um sinal de iniciação de detonação. A unidade (55) pode ser parte de um detonador (100) que recebe um sinal de iniciação não elétrico e explode de acordo com a demora determinada pelo circuito eletrônico. O alojamento do detonador (112) ou uma bucha opcional (22) fornece um invólucro para a unidade (55).<B> <MU> SHOCK RESISTANT ELECTRONIC CIRCUIT ASSEMBLY <MV> <D> A shock resistant electronic circuit unit (10) is stipulated, in which an electronic circuit is enclosed in an encapsulation (14) that fits into a surrounding casing (18,22) in shock dispersing contact. The encapsulation may have a series of ends (16.16a, 16b), ribs (24), or studs (70) that touch the casing. The encapsulation may contain a shock-absorbing material (14f) placed against the enclosure to protect the circuit from vibrations and a structural support material (14e) to protect the circuit against voltage. The circuit unit (10) may contain a capacitor (34) for storing an electrical signal and a set of regulating circuits for releasing stored energy after a predetermined delay. The circuit unit (10) can be part of a transducer circuit unit (55) that contains a transducer module (58), for converting shock wave energy into electrical energy for the electronic circuit, and the energy released can be converted to a detonation initiation signal. The unit (55) can be part of a detonator (100) that receives a non-electrical initiation signal and explodes according to the delay determined by the electronic circuit. The detonator housing (112) or an optional sleeve (22) provides a housing for the unit (55).
