    摘要： Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element.

    摘要： A method of operating an indicia reader for reading information bearing indicia (IBI) positioned in a field of view of the reader includes: transmitting a first laser light beam adapted for scanning an IBI on a target located a first distance from the indicia reader; transmitting a second laser light beam adapted for scanning an IBI on a target located a second distance greater than the first distance from the indicia reader; activating at least one of the first and second laser light beams; scanning at least one of the laser light beams with a flat unitary scan mirror to generate at least one of a first laser light beam pattern and a second laser light beam pattern; directing light reflected from the target from either the first or second laser light beams patterns through a common receive path; the common receive path including being reflected with the flat unitary scan mirror onto a focusing mirror; the focusing mirror directing reflected light along a directed reflected light path; the directed reflected light path including an optical filter outputting directed reflected light; converting the directed reflected light into an output signal with a photodetector; decoding IBI information derived from the output signal, wherein the operating steps are completed by devices supported in a hand held indicia reader housing and wherein an operator selectively activates the first laser light beam and/or the second laser light beam with a single action trigger.

    摘要： A weapons system is disclosed that provides hot-start navigational information to the Global-Positioning-System receivers on missiles prior to flight. The system comprises a Global-Positioning-System receiver that uses a classified red cryptographic key to decode the P(Y) signal from one or more of the Global-Positioning-System constellation of satellites. Once the P(Y) signal is decoded, one or more characteristics (e.g., the PRN code synchronization, the Doppler shift, the modulation bit sequence, etc.) of the signal is derived. These characteristics of the signal—and some other information including a black cryptographic key that comprises the red cryptographic key—are then provided to the Global-Positioning-System receivers on missiles prior to flight. By giving the missiles this information, the missiles are able to acquire the P(Y) signals themselves more quickly than they otherwise could, which enables them to determine their position more quickly than they otherwise could.
