    摘要： A method and apparatus are described for determining if an optical scanner is moving. In one embodiment the method for sensing movement of an optical scanner comprises the steps of providing an oscillating system comprising a flexible member, a magnet coupled to the flexible member, a coil disposed within a magnetically effective distance from the magnet, and sense circuitry coupled to the coil; generating a first electrical signal from the oscillations of the flexible member; amplifying the generated electrical signal; analyzing the first electrical signal to determine if the generated signal is indicative of movement of the optical scanner.

    摘要： Disclosed is a fully automatic bar code symbol reading system having at least one automatic (i.e., triggerless) portable bar code symbol reading device, and an associated base unit positioned within the data transmission range thereof without a physical wiring connection thereto. After each successful reading of a bar code symbol, the bar code symbol reading device automatically produces symbol character data representative of the decoded bar code symbol, synthesizes a group of data packets each containing the symbol character data, and then transmits the synthesized group of data packets to the base unit. Upon the successful receipt of one of the transmitted data packets and the recovery of symbol character data therefrom, the base unit generates an acoustical acknowledgement signal that is perceptible to the user of the bar code symbol reading device and indicates the transmitted symbol character data has been successfully received. In typical applications, a plurality of such bar code systems are used in physical proximity with each other, such as in conventional retail point-of-purchase (POS) environments. In accordance with the present invention, radio frequency(RF) carrier signals of the same frequency are used by each hand-supportable bar code symbol reading device to transmit groups of data packets to respective base units.

    摘要： An automatically-activated code symbol reading system (1) comprising a bar code symbol reading mechanism (4) contained within a hand-supportable housing having a manually-activatable data transmission switch (7A). During symbol reading operations, the bar code symbol reading mechanism (4) automatically generates a visible laser scanning pattern (10) for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern (3, 10) with a particular bar code symbol on an object (e.g., product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner. During the bar code symbol reading cycle, the user actuates the data transmission switch (7A) producing a data transmission control activation signal and enabling a currently or subsequently produced symbol character data string to be automatically selected and transmitted to the host system (5).
