Methods and apparatus for providing a relatively miniature injection molded scan motor, for example, for a retroreflective illumination system. An exemplary scan motor comprises a spring module that includes a static substrate and a dynamic substrate coupled together by an injection molded flexible spring. In an embodiment, the spring can be liquid injection molded. The scan motor also comprises a magnet and a reflective element that extends beyond the static substrate and/or the dynamic substra...

A method for determining a border of an image includes (a) receiving a composite image including a background image and a foreground image, (b) following one geometric feature (e.g., a line) of the background image, and (c) detecting two or more breakpoints in the first geometric feature where the foreground image superimposes the geometric feature. Actions (b) and (c) are repeated to detect breakpoints for a number of the geometric features. The border of the foreground image is determined by c...

A mirror module, comprising a collection mirror comprising an opening and a first reflective surface lying in a first plane, and a fold mirror coupled to said collection mirror, said fold mirror comprising a second reflective surface lying in a second plane, the second plane not being parallel to the first plane. In addition, said fold mirror may extend behind said collection mirror at an angle, wherein said angle is established so that a laser impinging on said fold mirror is reflected through ...

A driver of the invention adapts to scan peripherals using information in capability descriptor provided by scan peripherals or a capability descriptor selected based upon scan peripheral model information. A driver of the invention automatically determines a scan peripheral's capabilities using information from the capability descriptor, and uses the information to configure itself from a set of driver modules. A user interface and scan job are then run through options enabled by the appropriat...

In one embodiment, an apparatus comprises a scan circuit including at least a first and a second clock domain and a scan chain having a first plurality of scan cells positioned in the first clock domain and a second plurality of scan cells positioned in the second clock domain. A scan clock source, coupled to the scan chain, generates a first scan clock signal to the first plurality of scan cells and a second scan clock signal to the second plurality of scan cells. The first and the second clock...

A scanning system has a plurality of optical scan units. Each optical scan unit includes means for emitting light toward an item bearing an indicia. Each optical scan unit also includes means for receiving light reflected from the indicia and generating signals corresponding to the intensity of the reflected light. Also provided is a central control unit which includes means for combining together signals corresponding to the signals generated by at least two of the scan units to fully decode in...

A boundary configuration (Common Input/output CIO) for Generalized Scan Designs (GSD) in a single clock chip design includes at least one generalized scan design internal latch; a boundary scan clock input to the internal latch; an input/output cell connected to the internal latch; and at least one control line between the internal latch and the input/output cell. The CIO GSD is arranged and configured to operate in various modes including a function mode, a RUNBIST/INTEST/LBIST mode, an EXTEST/...

Utilization of a versatile scan-converted display which can operate with a variety of radar sweep signals or a variety of television raster sweep signals permits use of a purely serial main memory for refreshing the display at a rate much higher than radar data acquisition rates, thereby eliminating the need for an expensive random access memory in a multi-source, refreshed, unitary display. The disclosed sources which the scan-converted display will accommodate include air-to-air radar utilizin...

Periodic signals, for example sonar returns, to be displayed on a conventional television monitor are sampled and put into storage registers at a first rate. The storage registers are emptied at a second rate and the information is placed onto a video magnetic disk. For each sonar transmission a number of samples of the return signal are placed into, and read out of, the storage registers, during each revolution of the disk, as the return is coming in, to build up a television display signal ind...

A new system and technique for providing multi-mode radar operation from a ingle scanning radar antenna at conventional scan rates. A single radar antenna has a plurality of feeds forming individual main-lobe beams equal in number to the number of radar modes to be utilized. Each of the beams is separated in azimuth by a fixed angle .theta., and rotate together at the scan rate of the antenna. For each angle .theta. that the antenna rotates the radar mode is changed so that the antenna feeds are...
