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： Apparatus and method for displaying three-dimensional images with a display device. A blocking grid is positioned between a display device and a viewer, and a drive system oscillates the blocking grid in accordance with the display of a plurality of images. Each image is aligned with the grid and is structured such that each eye of the viewer sees only a displayed portion of a displayed image intended for that eye, thereby creating a three-dimensional effect.
