    Abstract: A device for imaging optical code symbols comprises no more than 1024 pixels, wherein each of the pixels has an aspect ratio that is greater than 2 to 1 with a short dimension not greater than 4 žm and not less than 2 žm, wherein preferably the pixels are arranged in a single row. Also provided is a bar code reader including a sensor for imaging a field of view of the reader comprising a single semiconductor device as described above. Apparatus and techniques are provided which reduce and/or eliminate the need for illumination of a target by the imager, thereby reducing the overall power consumed by the imager and/or its overall size. An imager with an increased working range is provided, as is a light emitting diode which produces a light with reduced line thickness.

    Abstract: An optical scanner (30) has a scanner component mounted to a leaf spring (34) for oscillatory motion about an axis. An electromagnetic coil (58) and permanent magnet (56) cause a force to be applied to the scanner component away from a central, neutral position. Bending of the leaf spring provides a restoring force biasing the scanner component back towards the neutral position.
