摘要： A scanner flipper integrity checking method, computer-readable medium, and apparatus is provided. In one embodiment, the method powers a motor for a predetermined amount of time. After the predetermined time has expired a wave is received indicative of the frequency of the oscillation of the flipper. Thereafter, the method uses the wave signal to determine whether there are two consecutive transitions indicative of movement by said flipper. In another embodiment, an apparatus is also provided which performs the similar features recited by the above method.

摘要： A scanner flipper oscillation frequency analyzing method, computer-readable medium, and apparatus is provided. In one embodiment, the method turns a laser off if the laser is on and receives a signal indicative of a flipper oscillation frequency. The method then compares the signal with stored parameters. Based on the comparison, the method adjusts the flipper oscillation frequency when a percentage variation between the signal and the parameters is above a predetermined value. If the flipper oscillation frequency is adjusted a Digital-to-Analog Conversion value associated with the adjustment is stored in memory. The signal received can be transition signals. In other embodiments, an apparatus and computer-readable medium is also provided which performs the similar features recited by the above method.

摘要： A scanner such as a bar-code scanner includes a scan-beam generator, a beam reflector having a first magnet, and a beam-sweep mechanism having a second magnet. The beam-sweep mechanism causes the reflector to sweep the scan beam across a target such as a bar-code symbol by exerting a force on the first magnet with the second magnet. In one example, attraction between the magnets holds the reflector steady in a non-sweep position. Conversely, in a sweep position, repulsion between the magnets causes the reflector to oscillate and sweep the scan beam across a target such as a bar-code symbol. Because it does not include a motor for rotating a beam-sweep mirror, the scanner is often smaller and uses less electrical energy than motorized bar-code scanners.

摘要： A device, arrangement, and scanner are provided which are compact, reliable, and cost effective. The device is generally of the type in which a moving beam is scanned along a target object, and light reflected from the target object is detected and analyzed by the device. The device is preferably mirrorless. In addition, the device preferably lacks an integrated scanning component which imparts motion to the beam. In this regard, the device is provided with components for interacting with a separate adjacent scanning component, as well as a flexible connection device.

摘要： A compact assembly for electro-optically scanning indicia includes an oscillatable component operative for focusing, and for sweeping, a light beam across the indicia and, optionally, for correcting for scan aberration. A laser diode for emitting the beam is inserted into a central opening surrounded by an electromagnetic coil to conserve space. A magnet on the component interacts with the coil to effect oscillation. A floating flexure returns the component to an equilibrium position.

摘要： A method for driving a resonant electromagnetically-actuated motor, such as those used to scan a light source for date reading applications, is described, wherein (in the preferred embodiment) drive current is applied when the back-EMF induced in the actuator coil is zero and has a specific slope, and that drive current is removed after the induced back-EMF voltage has changed by a predetermined constant value. It is shown that this drive means will drive the aforementioned motor across a scan angle which remains substantially constant regardless of changes in ambient temperature, changes in motor orientation, or externally applied forces.

摘要： A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.
