摘要： A non-contact light beam scan system small enough to fit into a hand holdable wand, pen or calculator size terminal incorporates a novel scan element which can scan at rates of ten to hundreds of scans per second in one or two dimensions. The device is immune to low frequency vibrations and can scan large angles of 60 degrees or more. Automatic trigger circuitry enables it to be used equally well in hand held or fixed mount applications. The depth of operating range is extended with a novel focal system which is integrated with the light source. The entire scanning system for generating a beam, focusing the beam electronically, scanning the beam, collecting light from a target and converting it into electrical signals, and automatically generating a trigger signal can work with industry standard low or high speed bar code decoders.

摘要： A scanning device for projecting a light beam against a target having information contained thereon which is to be scanned by the light beam; and in particular relates to a compact laser scanning device, such as a bar code projecting a laser beam, and which device incorporates a drive component such as a scanning motor for oscillating a scanning element or mirror at a high rate of speed within a specified angular range so as to cause the light or laser beam which impinges against the information on the target to be rapidly swept across the information in a scanning sequence. In particular, the structure is directed to improving the linearity of the oscillatory or "dithering" motion imparted by the scanning motor to the scanning element or mirror. Also contemplated is a novel method of utilizing the "dithering" or oscillating motion of the scanning motor for effectuating an improvement in the quality of the scan by the scanning device.

摘要： A coin routing gate for accepting coins in a coin handling mechanism requires only a low power electromagnet to hold the gate in an accept position. In the absence of power to the electromagnet, the gate passively rejects coins by gravity alone. The gate is arranged to accomplish minimization of the required holding force to minimize electrical power requirements thereby making the device suitable for low electrical power contexts such as coin operated telephone service.

摘要： An apparatus for use in identification of coins is disclosed in which a coin is passed through the electromagnetic field of an inductive coil wound on a ferrite core having two poles, at least one of which has a diameter less than the diameter of the smallest coin in the coin set to be identified. The poles are separated along the coin path by a distance approximately equal to the diameter of the largest coin in the coin set to be identified. The coin's effect on the electromagnetic field is measured when the coin is between poles and when it is adjacent each pole face.

摘要： A high speed non-contact beam scanning device sized and shaped to provide the ergonomic benefits of a pen or wand, yet can scan a wide angle moving beam across an information-bearing target in one or two dimensional scan patterns such as lines, rasters or other patterns in order to read information therefrom. The device is well suited for reading one or two dimensional bar-code or other printed matter. In order to achieve the high density optical packaging necessary for its high performance to size benefits the device employs a novel in-line or “axial” gyrating, or “axial” scan element. The axial scan element can accept an input light beam at one end and cause it to emerge from its opposite end as a scanned beam, propagating in the same general forward direction it had upon entering the element. Reflected light, which carries information contained on the target, is collected by an internal non-imaging light collector and is processed by signal processing electronics. All components are integrated into a thin low mass module small enough to fit in a pen. Communication from the device is achievable by a cable or by wireless means.

摘要： A method and apparatus for generating a scanning light beam for scanning a target using a light beam scanning system. In response to actuation of the scanning system by a user, only a single non-periodic pulse of current is provided to a scan element. The single pulse of current causes the scan element to move a light beam from a stationary equilibrium position to a first position at a first extreme end of a scan line that intersects the target. Immediately after the light beam reaches the first extreme end of said scan line, the scan element moves the light beam from the first extreme end of the scan line to a second extreme end of the scan line without application of external current. Thereafter, immediately after the light beam reaches the second extreme end of the scan line, the scan element brings the light beam back to the stationary equilibrium position without application of external current. Alternatively, the single pulse of current causes the scan element to move the light beam from a stationary equilibrium position at a first extreme end of the scan line to a second extreme end of the scan line, and immediately after the light beam reaches the second extreme end of the scan line, the scan element moves the light beam from the second extreme end of said scan line to the first extreme end of said scan line without application of external current.
