Abstract: An antenna apparatus for a hand-held symbology reader device having a housing and an elongated one-quarter wavelength antenna. A rotatable coupling member has an L-shaped conductor fixedly and electrically coupled to the antenna by a first end thereof. A second end of the L-shaped conductor is rotatably received by the housing. A ground plane of an electrically conductive material, having a plastic film coated thereon, is positioned within the housing. A washer of an electrically conductive material is electrically coupled to the second end of the L-shaped conductor, and is positioned in face-to-face juxtaposition with a portion of the ground plane. The washer and the portion of the ground plane form a parallel plate capacitor, with the plastic film forming a dielectric therebetween to capacitively couple the ground plane to the antenna.

Abstract: A circuit for detecting the motion of an oscillating motor driving a mirror for causing a light beam to scan. The circuit is included in a laser scanner for illuminating and reading bar codes, and detects the presence of conditions which prevent the motor from moving, such as a broken wire in a winding. The motor has two windings which are driven by a logic device to cause the motor to oscillate between two extreme angular positions. Each winding has two legs. The voltage on at least one of the legs is monitored when the leg is not being driven by the logic device, to detect the presence of an electromotive force voltage produced by motion of the motor. The monitored voltage is conditioned and transmitted to the logic device. In one embodiment, the monitored voltage is sampled twice and the two samples compared to provide an indication whether the motor is moving.
