摘要： Matched digital-to-analog conversions are performed in which, in each of N parallel channels, a digital input word is converted into a corresponding analog output. A digital sequence is generated, a time-varying analog signal having a predetermined relationship to the digital sequence is generated in response to the digital sequence, and the digital sequence and the time-varying analog signal are distributed to the N parallel channels. In each of the N parallel channels, the digital input word is digitally compared with the digital sequence, and, when the digital sequence is numerically equal to the digital input word, the time-varying analog signal is sampled to provide the analog output. The single time-varying analog signal derived from the single digital sequence at an operational speed at which high accuracy and low power consumption can be easily attained enables well-matched digital-to-analog conversions to be performed in any number of channels ranging from a few to many thousands.

摘要： Display contrast in electro-optical display devices is improved using a drive circuit including pixel drive circuits and a common drive circuit. The pixel drive circuits are connected to pixel electrodes of the display device, and are operable to generate respective pixel drive signals that alternate between a first high voltage and a first low voltage differing in voltage by less than or equal to a process-limited maximum. The common drive circuit is connected to a common electrode of the display device, and is operable to generate a common drive signal alternating between a second high voltage and a second low voltage differing in voltage by more than the process-limited maximum. The common drive signal is asymmetrically bipolar with respect to the first low voltage of the pixel drive signal.

摘要： A pointing device having a laser in a handheld housing is disclosed. The laser generates a light beam that exits the housing. A beam steering assembly causes the light beam to move relative to the housing. The pointer includes a housing orientation sensor that measures the orientation of the housing. A controller operates the beam steering assembly to compensate for changes in the housing orientation. Embodiments based on housing orientation sensors constructed from a gyroscope and a camera are described. In addition to stabilizing the light beam location, embodiments in which the beam steering assembly also causes the light beam to execute a fixed pattern can also be constructed.

摘要： The optical fiber tap establishes optical communication between a branch optical fiber and a main optical fiber and includes a housing, a serpentine main channel and a branch channel. The main channel is defined in the housing and is shaped to accommodate part of the main optical fiber. The main channel includes a coupling curve portion shaped to define a main coupling curve in the main optical fiber. The branch channel is also defined in the housing and is shaped to accommodate part of the branch optical fiber. The branch channel communicates with the main channel at the coupling curve portion of the main channel. Optical signals couple laterally between the main optical fiber located in the main channel and the branch optical fiber located in the branch channel. Optical communication between the optical fibers is therefore established.
