Abstract: A variable illuminator, for instance a device for scanning a beam of light, emits a selected amount of power to a plurality of spots across a field of view. The amount of power is determined as inversely proportional to the apparent brightness of each spot. In the case where the spot size is equal to pixel size, the device may operate with a non-imaging detector. In the case where pixel size substantially equals spot size, the output of the variable illuminator may be converged to produce a substantially uniform detector response and the image information is determined as the inverse of a frame buffer used to drive the variable illuminator. The illuminator and detector may be driven synchronously. In the case where an imaging detector is used, the variable illumination may be used to compress the dynamic range of the field of view to substantially within the dynamic range of the imaging detector.

Abstract: An antenna structure including a driven antenna element is formed on a substrate that is folded to provide a closed surface, causing the substrate to be nonplanar and spacing the driven antenna element from a base of the substrate. Adhesives on an outside surface of the substrate permit fastening of the folded substrate to a container or packaging. The substrate may have one or more resilient elbows formed by folding, to bias the antenna element carrying portion of the substrate from the base of the substrate. A modulation circuit may drive the driven antenna element. The flexible substrate may be folded into any of a variety of forms such as a substantially O-shape, a substantially oval shape, a substantially coil shape, a substantially spiral shape, and a substantially S-shape. Additional folds in the substrate may provide surfaces for mounting passive or parasitic antenna elements, such as reflectors and directors, to form a Yagi antenna structure. A planar substrate carries a driven antenna element coupled to a driving circuit and at least one passive antenna element to form a directional antenna structure. The antenna structure may include additional passive antenna elements to enhance directionality. A computing system and printer are configured to determine the appropriate spacing and the form the antenna elements on the substrate.

Abstract: A noise cancellation apparatus provides an inexpensive mechanism that is readily adaptable for printers and other equipment and devices that are used in areas where external noise is undesirable. In an embodiment of the present invention, a thermal printer includes a transport mechanism for transporting a media through the thermal printer and a thermal print head for printing on the media. At least one sound emitter is provided for generating an inverse sound signal to cancel noise generated by at least one noise source in the thermal printer. At least one microphone is provided for receiving sound signals from the at least one noise source. Each microphone is connected to an inversion circuit which inverts the received sound signals. The inversion circuit sends the inverted sound signal to one of the sound emitters, which emits the inverted sound signal, canceling out the noise. To ensure a proper phase relationship between the inverted sound signal and the sound signals generated by the noise source, the sound emitter is placed as close as possible to the noise source. Further, a low pass filter is provided between the microphone and the inversion circuit to filter out noise having a frequency greater than c/2d, where c is the speed of sound and d is the distance between the emitter and the noise source. Sound dampening materials are disposed in the thermal printer to cancel out the remaining high frequency noise that is within the range of human hearing.

Abstract: A clamshell printer having a base and a cover pivotally mounted to the base for movement between an open and a closed position, wherein the open position provides unhindered access to a media path and a print head in the printer. The printer may include a platen formed integrally therein or a platen rollingly supported in the printer. A media supply, such as a continuous sheet of linerless thermal media in the form of a roll may be quickly and efficiently drop-loaded into the printer, with no threading of the media required. Unhindered access to the print head is also provided. The printer may or may not include a drive mechanism for advancing the media through the printer. The print head is controlled by a microprocessor mounted to a circuit board in the printer. The circuit board may be spring-biased to urge the print head toward a printing position, which is located at an effective printing distance from the media and the platen. A window may be formed in the printer for observing the media supply.
