Abstract: An array of adaptive or fixed Herschel-Quincke tubes aligned in a circumferential or helical array about an inlet of a turbofan engine. The array of tubes effectively divide the acoustic energy generated by the engine. One of the energy components propagates within the tubes while the other propagates within the engine compartment. At some time certain, the acoustic energy in the tubes is reintroduced into the engine compartment to cancel the acoustic energy remaining in the engine as it propagates from the fan towards the inlet and outlet openings.

A compound is selectively adsorbed on the exposed patterned surface. The compound may comprise a first compound selectively adsorbed on the exposed patterned surface and a second compound selectively adsorbed on the first compound to form at least one bilayer. The patterned molecular self-assembly may further comprise a first set of bilayers and a second set of bilayers wherein the first set of bilayers has a different composition than the second set of bilayers.

Abstract: A method of implementing a time base change to a time-division multiplexec bitstream, for example an MPEG-2-compatible bitstream. The time base change is in response to a Time Base Change Flag. The bitstreams have video and audio packetized elementary streams, and each of these streams has a common time base. Each of the packetized elementary streams has a packet header, and packet data. The packet headers of the packetized elementary streams each contain a Presentation Time Stamp/Decoding Time Stamp flag field, a Presentation Time Stamp field, and a Decoding Time Stamp field. A time base change is indicated by a change in the PCR. The first step in changing the Time Base is receiving a discontinuity in the bitstream. This is used to disable synchronization of the video and audio bitstreams, and to mark a data byte in the bitstream associated with the Time Base Change Flag. The time base change is carried out and an interrupt is issued when the marked data byte arrives for decoding.

Abstract: Given compressed video which supports the coding of interlaced and noninterlaced frames through DCT and motion compensation, shared information is used in a macroblock for efficient conversion of inter-coded blocks to DCT intra-coded blocks. The shared information is also used to efficiently construct spatially reduced images without decompression.

Abstract: A recording head includes an ink chamber storing ink containing electrified toner particles and having an ejection opening 7 at one end and an ejection electrodes for ejecting the toner particles from the ejection opening. A counter electrode 6 faces the ejection opening. The recording head also includes a toner, concentration detection sensor detects a potential of the ejection opening 7, and a control unit for deciding a detected toner concentration and controlling a voltage to be applied to the ejection electrodes. The surface potential nearby ejection opening or the toner concentration and a voltage applying time are made to previously correspond to each other and are stored in a ROM table. A stable printing quality is obtained by detecting the toner concentration near the ejection opening by the toner concentration detection circuit and controlling a voltage to be applied to the ejection electrodes corresponding to a detected value.

Abstract: A two stage releasing interlocking system for mounting a medical device tool which includes a jaw head having an aperture. A collet having an upper portion and a lower portion is rotatably mounted within the jaw head. The upper portion of the collet has an aperture and is substantially aligned with the aperture of the jaw head. A moving means moves the lower portion of the collet into an opened position and a closed position with respect to the upper portion of the collet. Actuating means prevents the moving means from moving the lower portion of the collet into the opened position when the actuating means is in a first position and permits the moving means to move the lower portion of the collet into the opened position when the actuating means is in a second position.

Abstract: An apparatus for limiting the viewing angle of a display (e.g., a liquid crystal display (LCD)) of an electronic device including a housing for housing the LCD, includes a pivoting device coupled to the housing, and a plurality of retractable flaps movable between first and second positions and respectively coupled to the pivoting device. The plurality of retractable flaps are for limiting a viewing angle of the LCD when the flaps are moved from the first position to the second position.

Abstract: A detachable keyboard for a telephone set is provided in the form of a keyboard card clipped to the headset, which is completely detached from the body when unclipped. Wireless communication between the handset body and keyboard is used when the card is unclipped, while contacts are activated in the clipped position so that the wireless handset then functions as in the case of a non detachable keyboard.

Abstract: A method and/or apparatus is provided for bone fixation which includes oscillating a wire about a longitudinal axis, advancing the oscillating wire into the bone tissue, and leaving the wire in the bone tissue as a fixation element. The apparatus in the present invention may be a self-contained unit for providing oscillatory motion to a chuck configured for releasably engaging a K-wire or the like, or may include a drive gear for use with a conventional rotor and drill for accomplishing the same oscillatory action.

Abstract: A two-step masking process is disclosed for forming a ball limiting metallurgy (BLM) pad structure for a solder joint interconnection used between a support substrate and a semiconductor chip. A solder non-wettable layer and a solder wettable layer are deposited on the surface of a support substrate or semiconductor chip which are to be connected. A phased transition layer is deposited between the wettable and non-wettable layers. A thin photo-resist mask defines an area of the solder wettable and phased layers which are etched to form a raised, wettable frustum cone portion. A second mask is deposited on the surface of the support substrate or semiconductor chip, and has an opening concentrically positioned about the frustum cone. Solder is deposited in the opening and covers the frustum cone and the area about its periphery. When solidified, the solder, acting as a mask, is used to sub-etch the underlying solder non-wettable layer thereby defining the BLM pad.

Abstract: A memory (e.g. , Dynamic Random Access Memory (DRAM)) with self-programmable Built In Self Test (BIST). The DRAM, which may be a DRAM chip, includes a DRAM core, a Microcode or Initial Command ROM, a BIST Engine, a Command Register and a Self-Program Circuit. During self test, the BIST engine may test the DRAM normally until an error is encountered. When an error is encountered, the Self-Program Circuit restarts the self test procedure at less stringent conditions. Optionally, when the DRAM tests error-free, the Self-Program Circuit may restart testing at more stringent conditions to determine DRAM functionality limits.

Abstract: A motorized wheel-chair is equipped with one or more sensors for detecting obstacles. The detection method may be either radar or sonar (or both). An on-board computer processes these echoes and presents a visual or auditory display. With the benefit of these displays, the user issues voice commands (or exerts manual pressure) to maneuver appropriately the motorized wheelchair. One or more microphones pick up the sounds of the user's voice and transmit them to a computer. The computer decodes the maneuvering commands by speech-recognition techniques and transmits these commands to the wheelchair to effect the desired motion. In addition to speech recognition for decoding commands, voice (speaker) recognition is employed to determine authorized users.
