| 20080217410 | METHOD FOR WAKING UP IN-COUNTER FIXED SCANNERS - A method of waking up an in-counter bar code scanner from its standby mode comprises providing a sensor assembly attached to a touch plate. The sensor assembly comprises an oscillating magnet member affixed at one end and a permanent magnet attached at an opposite free end at the end of a flexible member. When a user touches the touch plate, the impact force exerted on the touch plate is transmitted to the oscillating magnet member causing the magnet to oscillate inducing an electrical signal in a pick-up coil provided near the magnet and wakes up the bar code scanner. | 09-11-2008 |
| 20080290170 | SCANNER SWITCHED TO ACTIVE STATE BY SENSED MOVEMENT IN QUIESCENT SCANNING MECHANISM - The disclosure generally relates to a method and apparatus 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. | 11-27-2008 |

| 20100079906 | Adaptive Feed Forward Rotational Vibration Compensation During a SEEK Operation - A disk drive assembly includes a disk drive, one or more accelerometers, a control circuit, and an adaptive feed forward circuit. The one or more accelerometers generate acceleration signals that are used to detect rotational vibration (RV) events on the disk drive. The control circuit is configured to: generate one or more control signals, which are based on a control signal from a host system and a compensation signal from the adaptive feed forward circuit, and generate a position error signal (PES) that indicates an error in a position of a disk drive head relative to a center of a track. The adaptive feed forward circuit generates the compensation signal, which compensates for the detected RV events based on the acceleration signals and the PES. The compensation signal accounts for self-induced RV events generated by a SEEK operation that repositions the head to a new track, wherein feed forward adaption is not disturbed by the SEEK operation. | 04-01-2010 |
