Title: Electrophoretic display (epid) employing grey scale capability utilizing area modulation
Inventor: DISANTO FRANK J
IPC: G02F1/167
Filed: 1991-07-15
Abstract: An apparatus provides grey scale capability for an electrophoretic information display (10). The electrophoretic informa-tion display (10) is an XY addressable display with each XY coordinate indicative of a given column (23) and row (25) and defin-ing a pixel. There are described means coupled to display for impressing upon the display a predetermined digital pattern to cause certain pixels in the display to be energized with respect to other pixels in the display where the combination due to the di-gital pattern causes a desired grey scale level to appear on a character or on the background of the display.

Title: Multiport multidrop digital system
Inventor: DUGGAN ROBERT J
IPC: H04L29/06
Filed: 1992-08-21
Abstract: A polled digital multiport, multidrop system is described. The inbound frame for sending information from remote terminals (42) to the host terminals (12) is arranged such that a plurality of bytes are provided by a first terminal, followed by a guard band, followed by a plurality of bytes provided by a second terminal, followed by another guard band, etc. The guard band permits signalling between the DSU (16, 36, 116) and the OCU (24), which in turn permits the OCU (24) to signal the MJU (28) that no data will be coming from the OCU (24). In this manner, control mode idle is accomplished and data mode idle is avoided. In addition, because of the guard band, if the delay from a remote site changes, no data will be lost. Means for monitoring the system (154) to follow changes in delay are also provided, and the system can cause a remote location to accommodate a change in delay.

Abstract: Described is a resonant-cavity p-i-n photodetector based on the reflection or transmission through a Fabry-Perot cavity incorporating non-epitaxial, amorphous layers with alternating refractive index difference electron-beam deposited on a light-gathering side of a commercially available photodetector. The materials of the Fabry-Perot cavity are be selectable from materials refractive indices of which fall with a large range (from n=1.26 for CaF2 to n=3.5 for Si) preferably from materials which are depositable in an amorphous state. The material combinations are selected so that only wavelengths resonant with the cavity modewill be detected. The microcavity of the RC-PIN design can also be deposited on any existing detector structure, without modification of semiconductor growth. Such a photodetector would be useful for wavelength de-multiplexing applications. Theease of layer deposition, as well as the high degree of tailorability of spectral position, spectral detection width, and maximum numerical aperture of efficient detection, make the RC-PIN attractive for use in wavelength demultiplexing applications. An exemplary RC-PIN photodetector includes a Si/SiO2 Fabry-Perot cavity electron-beam deposited on the InP substrate of a commercial InGaAs photodetector. The detection efficiency relative to a reference device was 52 percent at the resonant wavelength of 1350 nm, with a resonance width of 14 nm, and a 4 percent response for off-resonance wavelengths in the 1100-1700 nm range.

Title: Reciprocating table
Inventor: LOBEN RUDY E
IPC: B65H29/34
Filed: 1994-03-03
Abstract: A reciprocating table has a cam follower in the nature of an elongate slot extending transversely of the reciprocating path of the table. This slot receives a cam which is eccentrically mounted on a cam support wheel. The angular position of the cam support wheel is monitored by a rotary encoder and the cam wheel is driven by a bi-directional motor under microprocessor control. The microprocessor controls the motion of the cam such that an angular quadrant centred about the position of the cam defining the most extended position of the table is not used since the table is relatively insensitive to the motion of the cam within this quadrant. In contrast, the opposite quadrant extending about the most retracted position of the table is utilized so that the cam may be moved quickly to retract the table and yet the table is naturally decelerated.

Title: Cardboard Spacer/Seal as Thermal Insulator
Inventor: TAYLOR DONALD M
IPC: E06B3/663
Filed: 1994-10-11
Abstract: A multi-paned insulated light, such as a window, incorporates an interior panel spacer/seal that includes a thermal insulating layer of cardboard. The cardboard serves as a low cost insulating layer and may be used in conjunction with rolled or extruded metal spacer forms, so as to vastly diminish the thermal bridging effect normally present with such metallic sections. The cardboard spacer can be used adjoining either the "cold" pane or the "hot" pane of the multi-paned unit, or may be interposed between adjacent metallic sections, as a thermal break therebetween. The cardboard is preferably sealed with a surface sealing layer such as polyvinyl alcohol, to effectively preclude gas percolation therepast.

Abstract: A buffer/brake system is provided for carriers used in an automated assembly system.  The rear ends of the carriers are equipped with a flexible ring that is compressed when the queued carrier is struck by an oncoming carrier.  Compression of the flexible ring engages the sidewalls of the track support that accommodates the conveyor and the frictional engagement of the ring against the sidewalls of the track support act as a brake for the queued carrier.  The ring also acts to absorb the shock resulting from the collision between the queued carrier and the oncoming carrier.  The buffer/brake system is fully incorporated in and fixedly attached to the carrier and is not placed on the conveyor separately.

Inventor: LING FUYUN
IPC: H04B1/707
Filed: 1993-06-09
Abstract: A method and apparatus is provided for estimating signal power. The estimating is accomplished by correlating (206) an input data vector (204) with a set of mutually orthogonal codes to generate a set of output values. The input data vector (204) consists of data samples of a received orthogonal coded signal (202). Each output value corresponds to a measure of confidence that the input data vector is substantially similar to one of the orhogonal codes from within the set of mutually orthogonal coes. Finally, an estimate of the power of the received orthogonal coded signal is generated (208) as a nonlinear function of the set of output values.

Abstract: In a direct sequence spread spectrum receiver, multiple correlators are provided for despreading a spread data signal and a spread pilot signal. During a sync acquisition mode, pilot demodulators are connected to the correlators, respectively, and during a subsequent tracking mode, data demodulators are connected to the correlators whose outputs are combined by an adder to produce an output for the receiver. Despreading codes of different phase positions are generated and supplied to the correlators, respectively. During the sync acquisition mode, the phase position of each despreading code is successively shifted and high correlation values are determined from the outputs of the pilot demodulators. During the tracking mode, the phase positions of the despreading codes are set according to the high correlation values.
