Abstract: The object of the present invention is to provide a cellular phone to be used for emergency reports that performs GPS positioning by means of remote control from an emergency report center, and transmits positional information to the emergency report center. The emergency report cellular phone according to the present invention is constituted such that when an emergency report switch thereof is depressed, a call request is made to the emergency report center. The emergency report center transmits a response signal with the result that a call link is formed between the emergency report cellular phone and the emergency report center. Following completion of the telephone call, the emergency report center transmits a position recalculation command message, by means of a DTMF signal.

Abstract: A shielding structure for a circuit on a circuit board has a conductive box member for enclosing a region of the surface of the circuit board requiring shielding. The edge defining the open side of the conductive box member has a conductive rib protruding therefrom. A conductive pattern member is formed on the surface of the circuit board in the same shape as the edge of the conductive box member so as to encircle the region requiring shielding. The conductive box member is fastened on the circuit board by screws so as to cause the conductive rib to bite into the conductive pattern member and establish good electrical connection therewith. A conductive sheet can be inserted between the conductive box member and the conductive pattern member to further enhance the shielding effect.

Abstract: A radar detector/security device for cars in which the antenna structure of a radar wave detection circuit that drives a warning means when a radar wave is detected is utilized to radiate a local oscillation signal and receive a signal reflected from a dielectric body. The Doppler shift produced by the movement of the dielectric body is detected as a beat component of the local oscillation signal. This beat component causes an incorporated security function to activate a security circuit. The radar detection circuit or the security circuit can be selectively utilized.

Abstract: A band determining method in which radar signals of first and second frequency bands are received in the upper- and lower-heterodyne reception modes, using a local oscillation signal modulated with a low frequency signal, thus causing the phase relationship between the detected signal and the modulating signal to indicate which band signals are received.

Abstract: A radar detector capable of discriminating a prescribed radar signal from other undesired radar or interference signals by mixing an incoming electromagnetic wave radar signal with a local signal whose frequency varies with time within a fixed range of frequency repeatedly at regular periods, thus providing a beat signal; temporarily stopping the frequency sweep in response to appearance of dc components alone in the beat signal when the incoming radar signal matches the local signal in frequency; and watching the length of time for which the incoming radar signal matches the local signal in frequency. The reception of the prescribed radar signal is indicated using a sound-generating unit such as a speaker or a light-emitting unit.

Abstract: A radar detector is disclosed which comprises a radar wave signal receiver for producing a detection output when the incident radar signal is synchronized with a local oscillation frequency at a certain sweeping time, first and second pulse train signal generators for producing pulses with different cycles, and a cycle alteration circuit for altering the cycle of the second pulse train signal generator in accordance with a logic output corresponding to the detection output from said receiver, thereby synchronizing such cycle with the cycle of the first pulse train signal generator. The regular radar wave signal is discerned by the detection of coincidence between the output pulses from the first and second pulse train signal generators at certain time intervals. Consequently, the radar system is prevented from responding to interference noise or extraneous radar waves.
