Transmitter components (22, 24 and 30), associated with the tire (14) and operatively connected to the sensor (18), provide for transmission of a signal (32) that has a data rate and that indicates the sensed tire condition. A receiver unit (40), associated with the vehicle (12), receives the signal (32). The receiver unit (40) includes a plurality of antennas (42A-42N), each for receiving the transmitted signal (32), and a switching device (46) among the plurality of antennas at a rate that is quicker than the data rate of the transmitted signal (32).
Abstract:
A method of fabricating a vertical transistor of a memory cell is disclosed. According to this method, a semiconductor substrate is first provided. A pad layer is formed over the substrate. Then, a deep trench is formed in the substrate. In the deep trench, a trench capacitor is formed, a collar oxide layer is then formed on the sidewalls above the trench capacitor. A first conductive layer is formed above the trench capacitor. A second conductive layer is formed to fill the deep trench. The pad layer, the substrate, the first and the second conductive layers and the collar oxide layer are patterned. A first insulating layer is deposited to form the Shallow Trench Isolation. Both sides of the Shallow Trench Isolation and a portion of the second conductive layer are removed to form a buried strap and an opening. The pad layer is removed. A second insulating layer is formed over the substrate and the buried strap, and is removed after forming a well. A third insulating layer is formed on the substrate. After removing the third insulating layer on top surface of the substrate, the gate oxide is formed. Sequentially, a third conductive layer and a fourth conductive layer are formed to fill the opening and to cover the substrate. The third and the fourth conductive layers are patterned to form the gate. The source/drain regions and a fourth insulating layer are formed. The fabrication of the vertical transistor of a memory cell is completed.
Abstract:
The present invention relates to aqueous ink jet ink compositions comprising an anti-intercolor bleed agent, preferably a water soluble or ink-compatible agent. The inks typically also comprise water and at least a colorant of a dye, a pigment, or a mixture of dye and pigment. In one embodiment, ink jet ink compositions comprising an anti-intercolor bleed agent which is represented by {[(R)m—G)b]n}s(A)(X)p (Formula (I)), and ink jet printing processes which print the ink jet ink compositions in any desired printing sequence or order onto an optionally heated substrate are provided. The water-soluble or ink-compatible anti-intercolor bleed agent may form hydrophobic layers near the image boundary, thus preventing undesired mixing of two different neighboring inks which forms intercolor bleed. The ink jet ink compositions of the present invention exhibit reduced drying time, intercolor bleeding, and image defect as well as providing uniform ink images on transparencies.
Abstract:
A check valve assembly mounted for engagement with a valve seat includes a flapper valve and a lever arm. The flapper valve includes a bracket pivotably mounted along a first hemisphere of the valve seat, a valve plate mounted to the bracket along a region generally spaced from a periphery of the valve plate, and a mounting assembly adjustably joining the valve plate to the bracket. The flapper valve has a closed position with the valve plate in sealing engagement with the valve seat about the periphery of the valve plate. The lever arm is pivotably mounted to the valve seat along a second hemisphere of the valve seat opposite the first hemisphere. The lever arm includes a lever surface disposed for moving contact with an engagement surface of the bracket and a biasing means for biasing the lever surface toward contact with the engagement surface.
Abstract:
A cell-sensing unit is applied to a memory device having a cell associated operably with a complementary pair of bit lines and a word line. The cell-sensing unit includes a current sense amplifier having a first input side adapted to be connected to the bit lines, and a first output side, and a voltage amplifier having a second input side connected to the first output side of the current sense amplifier, and a second output side. The current sense amplifier is capable of magnifying a difference between currents flowing through the bit lines during a read cycle of the cell, and generates a corresponding voltage difference at the first output side. The voltage difference is received by the voltage amplifier at the second input side, and has a magnitude sufficient to enable the voltage amplifier to generate an output signal at the second output side corresponding to data stored in the cell.
Abstract:
A system (10) for remote convenience control of performance of a function includes a portable transmitter unit (14) and a receiver unit (18). In one embodiment, the system (10) is a remote convenience vehicle system. The transmitter unit (14) transmits a signal (16). The signal has a RF frequency at an unknown value within a range of values and conveys a message that contains a function request. Within the receiver unit (18) is superheterodyne circuitry (32) that has a mixer (44). The mixer (44) mixes a RF signal (42) coming from an antenna (28) and a reference frequency signal from a reference oscillator (46), and outputs an intermediate frequency signal (50) conveying the message. A bandpass filter (66) filters the intermediate frequency signal to pass a range of frequency values smaller than a known range of intermediate frequency values. Tuning control circuitry (70) automatically adjusting the bandpass range of the bandpass filter (66) to vary the bandpass range over the intermediate frequency range. Passage detector circuitry (72) senses the intermediate frequency signal passing through the bandpass filter (66) and automatically causes the adjustment of the bandpass range to stop.

A corresponding number of wheels, each defining a bore are rotatably engaged in-line with the combined box-like channel piece and front and rear brackets by a corresponding number of bolts extending through the front and rear brackets, the box-like channel piece and wheels. A distal tip of each bolt is threadedly engaged with a nut.
Abstract:
Microchannel plates for use in image intensifiers and night vision devices having both improved gain and signal-to-noise ratio are provided. The microchannel plates provide an initial electron impact area having a surface electron-emissivity coefficient greater than one (1) that is not occluded by low electron-emissivity conductive coatings. In one embodiment angulated deposition of a coating material is used to provide a high electron-emissivity initial electron-impact area while in another embodiment nonmetallic electrodes provide increased amplification of a signal electron. Besides improving gain and sensitivity, the microchannel plates of the present invention provide a higher signal-to-noise ratio, better resolution, high open area ratios and are significantly more cost effective to produce.
