摘要： A digital phase acquisition circuit includes circuits for detecting an edge of incoming data and a plurality of candidate clock phases, the circuitry further including logic for determining when the data undergoes a predetermined phase transition and at least one candidate phase which undergoes a digitally equivalent transition close in time to the data transition so as to enable the candidate phase to be used for choosing an appropriate clock phase for recovering information representative of the data. The circuit further includes logic for comparing a frequency of the chosen clock pulse and the data and adjusting at least one of these frequencies when a predetermined amount of drift therebetween is detected. The invention allows clock to be recovered within 1 bit time of a predetermined data transition occurring and allows an appropriate clock to be maintained through an entire packet regardless of packet length.

摘要： A lighting fixture includes a directional light source that produces a plurality of light rays. An optical module is coupled to the directional light source to focus the plurality of light rays into a beam of light rays to be output by the lighting fixture. The angular distribution of a majority of the beam relative to a vector normal to a ceiling on or near which the fixture is to be installed is in a range of 70 to 95 degrees. A blocking structure is used to block a direct view of the beam of light when the fixture is installed such that only indirect light is primarily visible from a viewer at least in or around a working plane substantially parallel to the ceiling.

摘要： A protocol for fiber-optic communication systems, or other communication systems based on transmission of unipolar pulses having wide dynamic range provides for information to be transmitted in packets having a predictable time slot for each transmitter. The receiver for such protocol has a first relatively long RC time constant mode conditioned for reception of data packets whose time of arrival is well predictable and a second relatively short RC time constant mode conditioned for reception of asynchronous randomly received packets. In the relatively long RC time constant mode, each packet includes a preamble having a first clamp interval in which no pulse is transmitted, and a second clamp interval in which a continual pulse is transmitted. A transducer on the receiver translates the packets of pulses into differential electronic signals on first and second outputs. First and second coupling capacitors, receive respective outputs of the transducer and AC couples the signals to respective second terminals of the capacitors. First and second switches connect the second terminals of the respective coupling capacitors to ground during the first and second clamping intervals, respectively, of the preamble. By clamping the outputs of the transducer to ground during the first and second clamping intervals, a DC level for each incoming packet is instantly established independent of the magnitude of the incoming packet. In the asynchronous mode, relatively low impedance discharge paths are established to reduce the time constant of the receiver. An output circuit, connected to the second terminal of each of the first and second coupling capacitors, supplies sequences of digital output signals in response to the differential signals.

摘要： A dip coat process material handling system and method for coating multiple layers of material on a plurality of workpieces, in particular for producing a multi-layer optical photoconductive drum, wherein a plurality of pipes are suspended from a carrier pallet which transports the workpieces through a dip coat cell housing various dip coating stations. The system includes a load/unload station, vertical and horizontal transport systems for transporting the carrier pallet having workpieces loaded thereon to the various dip coating stations, a drying/cooling booth, and a return conveyor system. The invention allows complete dip coat processing to be completed in an in-line configuration while the workpieces are attached to the carrier pallet, thereby eliminating load/unload steps at each dip coating station to provide efficient and flexible processing of materials.

摘要： A shroud for a gas turbine engine rotor stage is divided into a number of arcuate segments each of which is a trapezium. The segments are urged together by compression springs which attempts to make the assembly lengthen peripherally, by virtue of the chamfered ends 30 of the segments riding up each other. The completely circular shape of the shroud prevents that movement but as a result, a hoop load is generated which tends to move the segments radially outwards, thus achieving the same effect, along with a consequent increase in diameter. A cam ring and pins are used to control and reverse the movement, as desired. The shroud diameter can thus be altered to suit rotor expansion and contraction.
