Abstract: A vehicle door control system provides increased usability convenience to users by a function for automatically opening and closing vehicle doors. When a response signal has been continuously received over a predetermined period from a portable device in response to a request signal periodically transmitted from a vehicle unit, it can be inferred that the holder of the portable device has not merely passed by the vehicle but stays in the vicinity of the vehicle with the will to ride in the vehicle. Therefore, vehicle doors having the automatic opening/closing function are unlocked and automatically opened. This eliminates a need for the holder of the portable device to command the operations of unlocking and automatically opening the vehicle doors.

Abstract: An endoscope 2 has a CCD 9 incorporated in the distal part of an insertion unit 6 thereof. The sensitivity of the CCD 9 can be varied by applying a plurality of pulsating driving signals so as to change an electron multiplication rate. The endoscope 2 is connected to a processor 3 so that it can be disconnected freely. Information representing a type of endoscope stored in advance in a ROM 48 is transmitted to a controller 21 incorporated in the processor 3. The control means 21 uses a CCD sensitivity control means 12 to control the sensitivity of the CCD 9 according to the type of connected endoscope 2. Consequently, a view image of proper brightness can be produced irrespective of the type of endoscope 2.

Abstract: A backup communication is automatically executed if a smart ID does not come back from a portable device though a comparison ECU transmits a smart ID request. In the backup communication, the comparison ECU transmits an immobilized ID request through a coil. The portable device receives the immobilized ID request if a user brings the portable device close to an engine start switch. The portable device transmits the immobilizer ID to comparison ECU. The comparison ECU sends the immobilizer ID to an ID box. The ID box compares the immobilizer ID sent from the comparison ECU with the ID stored therein. If the immobilizer ID corresponds to the stored ID, an engine ECU allows an engine start.

Abstract: A visible light spectrum and a fluorescent light spectrum are received by a variable gain solid state imaging device provided to an endoscope. The variable gain solid state imaging device can be said to lower amplification levels for easily observed visible light spectrum, and higher amplification levels for low intensity fluorescent light spectrum observation. By varying the gain of the imaging device with the different spectrums, an object observed with the endoscope is displayed with approximately similar brightness in each white spectrum. A controller coupled to endoscope system switches different light spectrum to irradiate the observed object, while controlling amplification of the image device. The endoscope provides enhanced image detail to improve diagnosis and treatment of observed abnormal objects.
