Abstract:
EMI radiation in an integrated circuit device package (10) is reduced or eliminated by the introduction of a magnetic material into the encapsulating medium (14). The permeance of the magnetic encapsulating medium (14) affects the inherent series inductance of the lead frame conductors (16) to thereby reduce electromagnetic interference. Ferrite microbeads (30) are formed around the lead frame conductors (16) to contain the magnetic flux (32) generated by an electrical current signal and to attenuate the effects of mutual inductance.
Abstract:
The disclosure relates to battery powered hand-held data entry terminals (310) wherein a peripheral module may contain an automatically operating full image reader (313) and a wireless communication unit (312). The reader reads at least one full line of indicia and may comprise a laser bar code scanner or a flash type image reader. Preferably the reader has uniform resolution in orthogonal directions in the field of view so that an area image can be read at any arbitrary angular orientation and re-oriented as a stored digital image to a normalized orientation before decoding. The user interface (11, 12) may lie in a first longitudinally extended layer and the peripheral module (313) may lie in a second longitudinally extended adjoining layer. In normal reading disposition of the automatic reader (313), the user interface (11, 12) may be close to its normal orientation for user interaction therewith.
Abstract:
A sensor assembly includes a plurality of sensing sets, the sensing sets being organized into a sensing array. Each of the sensing sets includes a set of sensing elements for sensing physical phenomena. The set of sensing elements has a selectable integration time. The assembly also includes an analog-to-digital (A/D) converter operatively connected to the set of sensing elements for acquisition and conversion of an analog signal from each of the sensing elements into a digital signal. The assembly also includes a processor operatively connected to the A/D converter and to the set of sensing elements for managing the selectable integration time for the set of sensing elements and for analyzing the digital signals from each of the sensing elements in the set of sensing elements. The digital signals from each of the sensing elements are measured by the processor and an integration scaling factor for the set of sensing elements is computed and controlled by the processor to adjust the integration time.
