    摘要： Non-Imaging beam conditioning optical elements are disclosed which allow nearly full power usage from a light source, in a beam scanning information readout device such as a bar code reader. Light which would have been otherwise wasted by using stop apertures as in prior art scanning devices, is utilized efficiently by apportioning a greater amount of the light to the far out targets and less to the close in targets, effectively solving the problem of signal amplitude variation over a long working range. At the same time the novel optical elements provide multiple focal ranges which may be made to overlap thereby providing small beam cross sections for near and distant targets, significantly extending the depth of scanning range over prior art scanners. Amplification and signal processing of received light signals is simplified thereby eliminating the need for complex and fussy AGC amplifiers and limiters to deal with both strong and weak signals from close and distant targets respectively. Novel signal processing circuitry is also disclosed for adaptively processing received signals and for reducing variation associated with laser diodes, optical elements, and target related variables such as such as distance, reflectivity and contrast.

    摘要： A modular bill validator is disclosed consisting of easily separable modules and sub-modules. The main modules consist of a validation module and a removable, lockable or sealable stacker module. The validation module has slide out sub-modules can function independently without a stacker module or can accept replaceable stacker modules of different styles and sizes. The stacker module comprises a novel low power mechanism with moveable stacker bars to effect stacking of bills rather than fixed rails and a pusher plate thereby achieving an appreciable saving of space over prior art devices and permitting greater stacking capacity for bills. Various security options as well as improved sensing and validation techniques are also disclosed.

    摘要： A compact beam scanning information readout device and method for reading bar code or other information requires little or no orientation of the information to be scanned by virtue of its raster or omni directional scan capabilities. Only a single mirror is needed to generate two dimensional scans. A wide range of scan speeds are also possible for simple or complex one or two dimensional patterns. Scanning in two dimensions may be done with independent and continuous control of the scan in each dimension. The scan patterns may be electronically controlled to instantly achieve various orientations ranging from a straight line rotated about a point to continuously rotating complex patterns. A light collector, light detector, processor, and means of signal transmission are also included. In one embodiment the device is packaged in a housing resembling a wand or a thin flashlight and in another embodiment the device is packaged in a ceiling mountable housing which will not interfere with counter top work space. The invention is useful wherever beam scanning equipment is used especially for barcode scanning, pattern recognition, general beam positioning, and many other scanning applications.

    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 concentrator 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 transmission.
