Title: Sp-bpsk communication system for fading countermeasure
Inventor: MIZUTANI HIROMASA
IPC: H04L27/18
Filed: 1990-01-26
Abstract: PURPOSE:To attain a BPSK(Bi-Phase Shift Keying) communication system effective to fading countermeasures by setting an extraction band width in a receiver side carrier extraction section widely. CONSTITUTION:A signal generating section 14 of a transmitter generates an SP-BPSK signal by multiplying a data in terms of SP (Split Phase) code with a carrier and a carrier extraction section 70 of a receiver extracts a pi/2 phase shift carrier in an intermediate frequency. Then a synchronization detection section 42 multiplies the pi/2 phase shift carrier with the intermediate frequency to detect the SP-BPSK signal and a decoding section 76 decodes a data in the SP code from the detected SP-BPSK signal and the decoded SP code is converted into a Non Return to Zero(NRZ) code by a decoding code conversion section 78. Thus, the extraction of the carrier is attained even with the provision of a band width wider than a conventional width by one order of digit or over and the SP-BPSK communication system effective to fading countermeasures is attained.

Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To measure deterioration of an optical element, e.g. a touch panel, easily at all times without stopping the operation of an apparatus by applying a laminated film tape onto a body for detecting the quantity of light and then stripping the films sequentially. SOLUTION: A touch panel 1 comprises one pair or more of light emitting element(LED) 5 and a light receiving element (phototransistor) 6 arranged in the longitudinal and/or lateral direction. At the time of measuring the quantity of light, a laminated film tape 3 is applied onto the touch panel 1 (body for detecting the quantity of light) and then the films are stripped off sequentially. More specifically, a laminated film tape 3 thick enough to intercept infrared rays is mounted at a bezel part and the films are stripped off sheet by sheet until the infrared rays are transmitted. Transmitted quantity of infrared light can be measured based on the remaining number of films in the laminated tape 3 and the transmittance of film. Lifetime of touch panel 1 can also be determined.
