Abstract: A brushless DC motor, whose stator (10) is a combination of stator yokes (11, 16). a bobbin (14) on which a magnetic field coil (15) is wound and to which terminal pins are provided, and a base plate (20). The stator (10) is fixed to the base plate (20) by a protrusion (12c) provided on the bobbin (14) or by a flange (18a) formed on a bearing. The widths of magnetic poles (11a, 16a) of the stator, which are measured in the circumferential direction of the stator, are smaller than the width of one of the poles of a rotor magnet (5). Thereby, the position of a stable point is a maximum excitation torque position. Further, a magnetic pole sensing element (21) is provided at a place which is shifted in the circumferential direction from the middle position of one of the magnetic poles of the rotor magnet (5).

Abstract: 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 connection.

Abstract: An in-hub brushless permanent magnet DC motor has a radial working gap but uses coils wound in the axial direction of the motor. The coils generate fields that interact with the permanent magnet fields across the radial gap. The stator includes a plurality of angularly spaced stator teeth that have faces radially spaced across the gap from the permanent magnet. The stator teeth are connected to the base and extend axially into a cavity within the hub. The permanent magnet is a magnetically-segmented ring magnet located on an outer rim of the hub radially outwardly from the stator teeth. The magnetic flux from the permanent magnet is directed radially across the gap and into the stator teeth. Each stator tooth has an axially oriented post around which is wound a coil that generates an axial field. The axially-oriented part of each coil forms part of the magnetic circuit. The magnetic flux directed radially into each stator tooth is turned axially into the post and through the coil. The axially directed magnetic flux through the coil and post on each stator tooth is redirected from the axial direction to the circumferential direction by a ring magnetic flux guide. The ring flux guide interconnects the stator teeth and forms part of the magnetic circuit. Because the coils are wrapped around axial posts instead of the stator teeth a larger coil volume is obtained which results in higher motor efficiency and reduced heating of the bearing system. The angular spacing between adjacent teeth can be made very small or even eliminated since there is no need to locate a winding device between them as is required in conventional radial-gap motors. This results in a reduction in the motor cogging torque, which in turn allows a higher tooth/pole symmetry leading to better force balance and lower acoustic noise.

Abstract: 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.
