IPC: H04N9/87
Filed: 1990-10-26
Abstract: PURPOSE:To eliminate noise without giving modification to a composite signal by adopting the constitution such that a 2nd switch circuit selects an output of a end delay circuit when a 1st switch circuit selects a 1st output of a 1st delay circuit. CONSTITUTION:An NTSC system composite signal is inputted to an adder 1 and its output is delayed by a 262H delay circuit 4 and a 1H delay circuit 5. A switch circuit 6 selects an output of the 262H delay circuit 4 or an output of the 1H delay circuit 5 based on an output of a control circuit 10. An output of the switch circuit 6 is fed to a chroma inverter 8 and a delay circuit 9 and a switch circuit 7 selects an output of the chroma inverter 8 or an output of the delay circuit 9. Then the control circuit 10 receiving a vertical synchronizing signal applies 1/2 frequency division to the signal to generate a control signal inverted for each field and selects the switch circuits 6,7 simultaneously so that the switch circuit 7 selects an output of the delay circuit 9 when the switch circuit 6 selects an output of the 262H delay circuit 4. Thus, noise elimination is implemented without giving any modification to the NTSC composite signal.

Title: Pyroelectric infrared detector having frequency transfer function and manufacture thereof
Inventor: CHIN BANRAI
IPC: G01J5/34
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a pyroelectric infrared detecting unit having a high response in a low frequency area. SOLUTION: A rectangular open window is provided in an upper surface of a main body case 1 made of metal, and an infrared ray filter 2 is fitted in this open window. The pyroelectric signal to be generated by the absorption of the infrared ray by a pyroelectric element 3 is transmitted to a support 4 made of the chrome plated material. Radiation of heat of the pyroelectric element 3 and dispersion of heat thereof due to the convection is prevented by the heat insulating material 12, which is coated on the inner wall surface of the main body case 1 and which is made of the synthetic resin. Since the material for the support 4 is changed from the conventional silver plated material to the chrome plated material at a low heat conductivity, dispersion of heat of the pyroelectric element 3 due to the heat conduction is lowered.  Cut-off frequency of the pyroelectric infrared ray detecting unit can be deviated to a low frequency side, and the low frequency response of the pyroelectric infrared ray detecting unit is improved so as to enable the detection of an object, which moves at a low speed.

Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To provide the object individual recognition system that is used under an environment, unsuitable for 'light' as a communication medium where carrying of a recognition device is attained. SOLUTION: A transmission wave RD2 is received by a light-receiving circuit 6 of a data carrier 1, and the data carrier 1 is started from a sleep state. Then an identification circuit 8 confirms it from a reception wave RD 2 that a communication medium of the received wave is 'light'. Then, based on demodulated instruction data, identification data stored in an MPU circuit 11 are read/ written. The MPU circuit 11 sends an end signal to a modulation demodulation circuit 9 after the end and the modulation-demodulation circuit 9 conducts modulation, based on a communication medium that is designated in advance by a host computer 10 and stored in the MPU circuit 11.  That is, in the case that the communication medium is 'radio wave', BPS modulation and FSK modulation are conducted, and when the communication medium is 'light', FSK modulation is conducted and a signal modulated after modulation is sent to the identification circuit 8.

Title: Method for multi-channel sound transmission
Inventor: STEFFEN FRANK
IPC: H04R3/02
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To prevent reproduction of a loudspeaker at a succeeding position from being overlapped onto that of a preceding loudspeaker by stimulating many of spatial pulse replies from various positions in a same space and allowing a digital sound processor to overlap lots of acoustic signals received accordingly so as to improve the stability of pseudo sound sources. SOLUTION: Lots of spatial pulse replies are received and recorded at a position by using a plurality of unidirectional microphones through a multi-channel receiver. The received spatial pulse replies are overlapped in channels 7 of one digital sound processor and the resulting signal is emitted from loudspeakers 6 placed horizontally and loudspeakers 4 placed vertically via the digital sound processor 5. Thus, the effect of the loudspeaker at a succeeding position due to localized sound sources onto a listener not accurately placed in the middle of the axial line of the two loudspeakers 4 is sufficiently avoided.
