摘要： A method, system, and computer program product for implementing presence detection is provided. The method includes a first mode of a tri-modal application that monitors a field-of-view via a presence detection function of a scanner. The method also includes implementing a second mode of the tri-modal application when a change to the field-of-view is detected and a specified threshold of change is met. The second mode includes activating selected system components of a terminal device, which in turn include a processor and the presence detection function. The second mode also includes fully activating the scanner and monitoring the field-of-view for determining a bar code image. The method further includes initiating a third mode of the tri-modal application when the bar code image is detected at the scanner. The third mode includes activating an illumination component of the scanner, reading the bar code image, and deactivating the illumination component when the bar code image has been read before returning to the second mode.

摘要： A printer employs a print head having a wire column arranged at an angle between 0.degree. and 90.degree. relative to a permitted line of motion of the print head. This angled print head allows for both portrait and landscape printing. Portrait mode printing is performed by controlling movement of the angled print head along the permitted line of motion during printing of each line of images. Landscape mode printing is controlled by maintaining a stationary position of the print head while the print receivable medium is moved in a direction perpendicular to the permitted line of motion of the print head.

摘要： An apparatus and method for ultrasonically communicating information from a source to a destination and for acknowledging receipt of that information by the destination. The apparatus includes at least one processor, at least one transceiver, and at least one display device, each display device having a unique identifier. The processor communicates information for broadcast to the transceiver. The processor also performs digital signal processing for detecting an acknowledgement signal within a narrow bandwidth. The transceiver ultrasonically broadcasts an identifier and associated data to display devices within the broadcast area, and also receives ultrasonic signals. A display device includes a transducer, a comparator, a memory, a display panel, and logic. In the communication method, a processor, a transceivers, and a display device communicate by initially associating data with a unique display device identifier. The processor communicates the identifier/data pair to the transceiver, which in turn ultrasonically broadcasts the identifier and associated data to display devices within the broadcast range. If the received identifier matches the unique identifier of the display device, then an acknowledgement signal is generated and the data is displayed at the display device. The processor determines whether the acknowledgement signal was generated within a defined bandwidth by performing digital signal processing.

摘要： An optical bar code scanner uses an improved deflector which deflects a scanning beam along different path lengths within the scanner. The beam is focused at different focal points outside a scanning window of said scanner. The different focal points provide a continuous depth of field with significant range. In one design the rotating deflector is configured as an asymmetrical polygon having a plurality of flat mirrors mounted on a support structure.
