Title (EN) OPTICAL DATA SENSING SYSTEM INCLUDING POWER CONTROL MEANS
(FR) SYSTEME OPTIQUE CAPTEUR DE DONNEES COMPRENANT DES MOYENS DE COMMANDE DE PUISSANCE
Abstract: front page image
(EN)An optical data sensing system includes an optical wand (14) adapted to optically sense a record member containing data encoded in a bar code, and a reading circuit (20) for decoding the sense data for transmission to a computer (26). A power source (30) is coupled via a switch (36) to the wand (14) and the reading circuit (20). A control circuit is effective to operate the switch (36) periodically to determine whether the wand (14) is sensing the record medium. When the wand (14) is sensing the coded data, control signals are provided to operate the switch (36) for at least a predetermined time such that the reading circuit (20) can process the sensed data. An economy in power supply is achieved.
(FR)Un systeme optique capteur de donnees comprend une baguette optique (14) adaptee pour capter optiquement un element d"enregistrement contenant des donnees codees dans un code a batonnets et un circuit de lecture (20) pour decoder les donnees captees et les transmettre a un ordinateur (26). Une source d"alimentation de puissance (30) est couplee via un commutateur (36) a la baguette (14) et au circuit de lecture (20). Un circuit de commande actionne le commutateur (36) periodiquement pour determiner si la baguette (14) detecte le support d"enregistrement. Lorsque la baguette (14) detecte les donnees codees, des signaux de commande agissent sur le commutateur (36) pendant au moins un temps predetermine tel que le circuit de lecture (20) peut traiter les donnees captees. On realise une economie d"energie d"alimentation.
