Title: Reader for cryptographic code
Inventor: HIRANO MASAO
IPC: G06K7/12
Filed: 1982-02-17
Abstract: PURPOSE:To make a more precise read of cryptographic codes, by utilizing the luminescence wavelength and a extinction of phosphorescence phenomenon of a fluorescent body in combination. CONSTITUTION:A timing generating circuit 8 generates timing pulses P1 and P2 for driving an ultraviolet-ray emitting device 3 and an infrared-ray emitting device 4 respectively and timing pulses P3 for deciding the detection point of time of an afterglow. A level discriminating and a gate circuit 7 decide on whether input signals from photodetectors 5 exceed threshold values or not. Afterglow detection signals B1 from the fluorescent bodies E for showing an accelerated phosphorescence are greater than a threshold value at this point of  time, afterglow detection signals A1, C1 from the fluorescent bodies L for not  showing an extinction of phosphorescence are lower than a threshold value at  this point of time so no pulses appear in output signals A2 and C2. Therefore, a cryptographic code expressed by the fluorescent bodies 1 at three points is 010.  Those data of a circuit 9 are read by a CPU10.

Title: Preventive vehicle safety device
Inventor: TAMIYA NORIHIRO
IPC: B60W30/00
Filed: 1993-02-15
Abstract: PURPOSE:To speedily detect an obstacle that a driver is likely to recognize late by detecting a direction in which the driver pays attention and controlling the detecting function of a peripheral body detecting means so that an area different from the attention direction is detected. CONSTITUTION:When a driver's own vehicle 7 travels straightly through an intersection where no signal is installed, the driver turns the sight to the right so as to pay attention to an obstacle from the right direction in approaching the intersection. At this time, a driver's attention direction detecting means 6 detects the direction 9 of the sight and the visual field 10. A body detecting function control means 5 turns a detection direction 11 of the peripheral body detecting means 1 to the left different from the sight direction 9 of the driver according to the detection results. Consequently, an obstacle 8 coming from the left direction can be detected early and the recognition delay of the driver can be prevented.
