A wireless personal communication system (100) comprising a transmitter and a receiver (117) arranged to communicate via a radio frequency link (105, 115) is provided. The transmitter (117) breaks a message to be sent into segments, and then encodes the segments into a like number of individual packets, the kth packet containing two segments, namely, a version of the present or kth segment and a version of the preceding or (k-1)th segment. Thus, each message segment is sent twice, in adjacent packets. Each packet is then transmitted on the radio link (105, 115), the sequence of packets being received by the receiver (117). The receiver (117) then decodes each packet into its two message segment components. Thus, the kth received packet contains two segments, namely, a version of the kth segment and a version of the (k-1)th segment. Thus, each individual message segment is received two times, the first occurrence resulting in a first version, and the second occurrence resulting in a second version, in adjacent packets. After receiving the second version of any given message segment, the receiver (117) selects the version of that segment that is the highest quality, or lowest error. The higher-quality version thus selected is saved and used for message reconstruction, whereas the other lower-quality version is discarded. As a result of this process, the receiver can faithfully reproduce the original message. In the preferred embodiment, the frequency for each packet to be sent (or received) changes according to an algorithm or pattern specially determined to minimize the probability that any two packets immediately adjacent to one another might be degraded.

 Appl.No PCT/US1992/000342 Applicant EASTMAN KODAK COMPANY Inventor WILSON, James
In an electrostatographic reproduction apparatus there is provided an operator control panel having a display screen indicating certain standard selectable features for a copying operation including copy format (simplex to duplex, etc.), paper supply source, copy quality, magnification and exit location with plural displayed options for each feature. Keys and buttons are provided for altering the display to indicate a displayed selected option for each. For more complex operations the display may be changed to display various operator selectable special job level features for a copying operation available on a job level basis. The display is further alterable to display various operator selectable special page level features for a copying operation specific to reproducing a selected page of a multisheet document job. Thus, a layered approach is provided in the series of displays from a standard features presentation which a casual user would be comfortable using, to a job level features presentation for a more complex reproduction at the job level, to a page level features presentation for designation of specific page level features for selection. User friendliness is enhanced with consistent use of indicia identifying a feature under consideration, selection of such feature and whether or not additional screens must be called up to further define that feature and further identifying other features which may not be chosen when a certain feature is chosen.

A set of scan latches (SL) is partitioned into unique groups (243a, b, c) where each group is addressable by a group initializing circuit (350, 360). The group initializing circuit initializes all the latches of an addressed group to a predefined state thereby quickly loading a test vector into the addressed group of scan latches while leaving other latches undisturbed.

 Appl.No PCT/US1992/001823 Applicant ALLIED-SIGNAL INC. Inventor TERVO, John, N.
The invention is a butterfly-type check valve (8) wherein the valve plate (18) moves translationally relative to a pivot axis (90) and incident to its own rotational movement. The invention employs biasing means (102, 104, 108) for initiating movement of the valve plate when the latter is at a closed rotational position, thereby eliminating the need for a pilot valve.

 Appl.No PCT/US1992/001576 Applicant THE BOARD OF REGENTS OF THE UNIVERSITY OF WASHINGTON Inventor EL-SHARKAWI, Mohamed, A.
A system and method for determining and providing reactive power compensation for an inductive load. A reactive power compensator (50, 50') monitors the voltage and current flowing through each of three distribution lines (52a, 52b, 52c), which are supplying three-phase power to one or more inductive loads. Using signals indicative of the current on each of these lines when the voltage waveform on the line crosses zero, the reactive power compensator determines a reactive power compensation capacitance that must be connected to the lines to maintain a desired VAR level, power factor, or line voltage. Alternatively, an operator can manually select a specific capacitance for connection to each line, or the capacitance can be selected based on a time schedule. The reactive power compensator produces control signals, which are coupled through optical fibers (102/106) to a switch driver (110, 110') to select specific compensation capacitors (112) for connections to each line. The switch driver develops triggering signals that are supplied to a plurality of series-connected solid state switches (350), which control charge current in one direction in respect to ground for each compensation capacitor.

A non-constrained total joint prosthetic replacement device (10) for the metatarso-phalangeal joint. A first component (12) comprises a convex-bearing surface (24) and a rearwardly projecting stem (22) configured to be received in the resected metatarsal bony shaft (16) and a second component (14) includes a concave-bearing surface (40) and a stem (36) configured to be received within the resected phalangeal bony shaft (18). A non-bearing intermediate land (26) offsets the convex-bearing surface (24) of the first component (12) from the stem (22), allowing a full range of anatomical motion notwithstanding the presence of bony growth.
