Patent JP-S627266-A (JP)
Title: Picture processor
Inventor: NIWA HIDEAKI
IPC: H04N1/40
Filed: 1985-07-04
Abstract: PURPOSE:To accomplish accurate binarization of a picture signal in accoreance with the existence/absence of noise and the characteristic of the picture signal by providing a means to decide a threshold for the binarization and altering the pursuit of the means in accordance with characteristic of the picture signal. CONSTITUTION:The threshold to convert the inputted picture signal into white- and-black binary information is determined by a half-wave rectification circuit and a peak holding circuit. An amplifier 15, together with diodes D1 and D2 and a resistor R4, constitutes the said rectification circuit, and the circuit's output is inputted to the peak holding circuit consisting of diodes D3-D5, resistors R5 and R6, and a capacitor C1. This circuit reserves a peak value as the accumulation potential of the capacitor C1. The C1 is charged in negative potential by the output from the amplifier 15, but is charged through the diode D5 at falling of a signal, but is discharged when the signal rises. By thus altering the pursuit of the threshold at the raising and the falling of the signal and setting it, the accurate binarization of the picture signal is attained.

IPC: H04W88/04
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a radio communication device capable of surely recognizing incoming call to its own device even when communication with a base station is impossible. SOLUTION: A portable telephone set 1A measured an electric field intensity indicator RSSI at each prescribed time, and when an owner of the telephone set 1A enters a reinforced concrete building 2, the value of the RSSI is reduced in accordance with the depth of the building 2. When the value of the measured RSSI is reduced to a prescribed value or less, namely immediately before communication with a base station 6 becomes impossible, the telephone set 1A requests the substitutive detection of an incoming call to the telephone set 1A to another portable telephone set 1B. Upon receiving the incoming call substitutive request from the telephone set 1A, the telephone set 1B detects also a terminating call to the telephone set 1A in addition to incoming call to the set 1B itself.  When substitutionally detecting a incoming call to the telephone set 1A, the telephone set 1B informs the telephone set 1A of the substitutional reception of the incoming call.

Filed: 1980-10-21
Abstract: PURPOSE:To fetch accurate time information into a computer, by updating the time of a time register prior to a change in actual time by a system which reads the time information in the computer. CONSTITUTION:In a time information setting circuit, the level of an input acutal- time clock signal CLK-R is inverted by an inverter 18 to obtain a fundamental clock signal CLK-S, which is outputted to the second register 12 of a time register 11. Therefore, time information indicated by the time register 11 leads the acutal time by nearly the half period of the clock signal CLK-R, so a computer fetches stable time information, held in a time information register 22, at the timing of an interruption signal INT. This time information is coincident with the actual time by the timing of the interruption signal INT, so that the accurate time information if fetched in the computer.
