摘要： A ship is constructed of a skeleton, including a hull, horizontal decks, and vertical support posts, all permanently joined together. At least some of the interior walls are made of a composite material of reinforcement embedded in a plastic matrix. These non-structural interior walls are semi-permanently attached to the skeleton with attachments, so that they may be readily rearranged to reconfigure the interior of the ship. The majority of the apparatus and infrastructure of the ship is affixed to the skeleton but not to the non-structural walls.

摘要： A system and technique for directing intensity modulated electromagnetic energy. The inventive system (10) includes an intensity modulated source of electromagnetic energy (12). Individual elements (22) in an array of energy directing elements (15) are activated in sync with the modulation of energy source (12). In a particular implementation, the source (12) is a laser. The intensity of the laser is reduced during each successive field per frame. The energy directing elements (15), in this case--light directing elements, are implemented with an array of digital micromirrors. The light source (12) is modulated in intensity in accordance with a fixed modulation scheme. The mirrors (22) are selectively activated relative to the light source modulation scheme. Hence, the invention provides a gray scale output while allowing the time between mirror flips to be constant. This allows the system clocks to run synchronously and greatly simplifies the writing of data into the display as the time available for writing each bit is constant.

摘要： An on-substrate driver circuit for a display line of a liquid crystal display having an amplifier connected in conjunction with an amplifier input capacitor, a sample/hold capacitor and three switches. The circuit operates in a first compensation mode wherein the first and second of the switches connect both a null reference voltage and the amplifier output voltage to the amplifier input capacitor, effectively nulling out or compensating for offset between the turn-on threshold, and hence the output, of a plurality of amplifiers on the display. After compensation, the circuit is switched to an operational mode wherein the first and second switches are open and a third switch connects the analog display signal to the sample/hold capacitor. A second preferred embodiment employing a double buffer including two consecutive, serially connected amplifier stages as described is also disclosed. In practice, a plurality of such double buffer circuits are arranged along the edge of a liquid crystal display panel and supplied with a common input signal by a single off-substrate input signal line.
