Filed: 1988-08-08
Abstract: PURPOSE: To optimize lighting in response to road conditions by providing a light stable crystal on a scattering plate in a light path, radiating the light of a control light source on the crystal, and switching the light penetration state of the crystal. CONSTITUTION: Light sent out by an incandesent lamp 1 is directed to an optical plate 1012, that is, a scattering plate 16 via a reflector 10. A light bistable crystal is arranged inside the scattering plate 16. When the incandesent lamp 11 is switched on, insufficient luminous intensity for switching the crystal is radiated, and the crystal absorbs the whole light. Additional light is radiated, and when the luminous intensity reaches a threshold value for switching the light penetration state of the crystal, the crystal is suddenly switched from light non-penetration to light penetration. When the additional luminous intensity is cancelled, the crystal absorbs the whole light again. The additional luminous intensity is formed by a control light source, particularly a laser 20 or 30.  The control light source is controlled by a data processing device 50 depending on the control signal of a sensor device 51 recognizing the light state of a road.

Title: Moving body detecting method
Inventor: TANIZAKI TETSUYA
IPC: G06T7/00
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To calculate the displacement quantity with a small error and high precision even under wide-range field angle conditions by fitting the cross correlation output by using an optional function, and predicting a maximum value and calculating the movement quantity between pixels. SOLUTION: Instead of a conventional maximum value detecting circuit 12, fitting 16 by, for example, a quadratic function is employed. A conventional mutual correlation method has a speed error since the movement quantity of a vehicle is obtained only in pixel units, so the movement quantity not in the pixel units, but between pixels is calculated. By the conventional cross correlation method, the maximum pint of cross correlation values is calculated as the displacement quantity, but the real displacement quantity is present between the maximum point (1st peak point of the cross correlation values and the next maximum point (2nd peak point). For the purpose, prediction (interpolation) between the 1st peak point and 2nd peak point is performed to calculated the real displacement quantity and the precision can be improved.

Title: Frame synchronizing circuit
Inventor: KINOSHITA KAZUYUKI
IPC: H04B7/26
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To contrive to save power by stopping the receiving operation in an unnecessary time slot as long as possible when frame synchronization is not established. SOLUTION: Decoded data from a receiving circuit 2 is first calculated by a CRC arithmetic part 5. When the result of the arithmetic is correct, it is regarded that a correct CRC arithmetic result is obtained based on a CRC bit existing at the prescribed position of each time slot so that the boundary of the time slot can be set by basing on the position of the CRC bit as a reference. At this time a frame number and a slot number obtained based on a unique code obtained by a unique code judging part 3 are loaded as a initial value to a counter within a TDMA (time-division multiplex communication) managing part 6.  As a receiving position is known by the value of a counter in spite of not always detecting the synchronizing bit of received data, reception is operated only at the time of a necessary time slot and the operation of a receiving part 1 can be stopped at the time of unnecessary time slot.
