Title: Automotive safety signal
Inventor: BARTOFFY DAPHNE E
IPC: B60Q1/26
Filed: 1991-01-09
Abstract: ABSTRACT             It is well known that in any vehicle, such as a car or motorcycle, the lights that indicate a braking action to others who may be following, are energized by some mechanism linked to the brake pedal. In this invention, the AUTOMOTIVE SAFETY SIGNAL is used to energize a set of lamps at the rear and front of the vehicle when-ever the vehicle is caused to decelerate. This will occur before the application of the brakes and the consequent turning on of the brake lights. As a result, following traffic will have an earlier indication of the driver's intentions and thus be better prepared to act accordingly. The green light in front will indicate a slow down action to the street cross walkers.

Patent CA-2044962-A1 (CA)
Inventor: MATSUO KATSUHIKO
IPC: C25D13/12
Filed: 1991-06-19
Abstract: ABSTRACT OF THE DISCLOSURE      A shaped or unshaped article of a non-ferrous metal sheet having an organic, surface coating film containing conductive and/or semiconductive,  fine particles, is integrally bonded with a shaped or unshaped article of a steel sheet having or not having an organic, surface coating film; and this integrated body is subjected simultaneously to electrodeposition coating.    The non-ferrous metal sheet having an organic, surface coating film containing conductive and/or semiconductive, fine particles shows excellent electrodeposition coating characteristics which can be easily regulated.   Hence, integral coating after bounding with a steel sheet gives the same degree of film thickness and surface smoothness on both of the non-ferrous metal and steel sheets.   This method is particularly suitable for the coating of automobile bodies integrally composed of non-ferrous metal and steel sheets ( needed by recent demand for lighter-weight automobiles ), ensuring energy- and labor-saving and giving final products of uniform finish.

Abstract: A power control system for a cellular mobile telephone system in which system users communicate information signals between one another via at least one cell-site using code division multiple access spread spectrum communication signals. The power control system controls transmission signal power for each cellular mobile telephone in the cellular mobile telephone system wherein each cellular mobile telephone has an antenna (70), a transmitter (84), and a receiver (72, 74) and each cell-site also has an antenna (52), a transmitter (62), and a receiver (54, 56). Cell-site transmitted signal power is measured as received at the mobile unit. Transmitted power at the mobile unit is adjusted by transmit power control units (76, 80) in an opposite man-ner with respect to increases and decreases in received signal power.      A power control feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit transmitted pow-er is measured by the received power measurement unit (60) at the cell-site. A command signal is generated at the cell-site and transmit-ted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell-site received signal pow-er. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level.
