Title: Use of iteration to improve the correction of agc dependent channel-to-channel gain imbalance
Inventor: PRINGLE RICHARD C
IPC: G01S13/88
Filed: 1992-06-18
Granted: 2005-03-22
Abstract: A method and apparatus that uses iteration to achieve a better prediction of the values of the commands need to balance the gains of .SIGMA. + .DELTA. and .SIGMA. -.DELTA. channels of a radar guidance system, when an imbalance occurs due to a change caused by the AGC circuitry. An improved method of measuring channel-to-channel gain imbalance versus AGC measurements is provided, which produces modified input values that are used as commands that correct the mismatch during missile flight so that residual error is minimized and more accurate guidance is achieved. The present method is implemented by measuring the gain imbalance at predetermined AGC points during system calibration, and iterating these measurements to produce a relatively small channel-to-channel gain imbalance at the .DELTA.AGC amplifiers. The measured imbalance is then converted to .DELTA.AGC commands and applied to the .DELTA.AGC amplifiers. The resulting gain imbalance is measured and this value is added to the originally value. This iterated value is again converted to .DELTA.AGC commands and applied to the .DELTA.AGC  amplifiers, and again the imbalance is measured, and is added to the first measurement. This procedure is repeated until a satisfactory level of error is measured which produces the proper correction factor that balances the channel-to-channel gains for each value of AGC. These correction factors are stored in a lookup table and are subsequently applied to the missile during flight. The improved apparatus of the present invention comprises a .DELTA.AGC controller containing a lookup table that contains the correction factors determined using the above method and an amplifier control circuit that responds to the correction factors to apply modified gain factors to the .DELTA.AGC amplifiers. These correction factors are applied to the .DELTA.AGC amplifiers during operation of the guidance system to achieve more accurate missile guidance.

Title: Design and construction of non-infectious human retroviral mutants deficient in genomic rna
Inventor: GORELICK ROBERT J
IPC: C07K7/08
Filed: 1990-10-31
Granted: 2000-05-23
Abstract: The present invention defines a biological role for the following sequence of amino acids that is found in the nueleocapsid domain of the gag precursor polyproteins of ail replication-competent retroviruses: -Cys-X-X-Cys-X-X-X-X-His-X-X-X-X-Cys-, wherein X represents variable amino acids. The invariant residues constitute pan of a vital protein structure, at least one of which are found in all retroviruses and which are invotved in the selection and packaging of genomic viral RNA into infectious virus particles. Disruption of this structure leads to the formation of virus-like particles which appear to be structurally normal, but which do not contain the normal complement of viral RNA. Therefore, their infectivity is drastically reduced or completely eliminated. The infectivity of any zetrovirus, including human retroviruses, and more particularly human immunodeficiency virus (HIV), can be drastically reduced or completely eliminated by generating mutants that lack some or all of the invariant residues required to form the structure. In addition, any means of disrupting the functions of this array will in turn disrupt the viral life cycle. Thus, with the knowledge provided by this invention, chemotherapeutic reagents aimed toward this array may be devised.

Inventor: GROBMAN WARREN D
IPC: H01L23/538
Filed: 1990-10-10
Granted: 1995-02-14
Abstract: An electronics system and method are provided which allow engineering changes to be made to a substrate without requir-ing the addition of fly wires and without requiring relatively large areas of pads for attaching these wires. Each device site is sur-rounded by a series of engineering change ring patterns (43, 44, 45). A series of engineering change patterns allow change inter-connections between device sites to be made. Fan-in metallizations (60) extend inwardly to the device sites from these change patterns, with a series of vias (63, 69) making surface connections adjacent to the ring patterns. Fan-out metallizations (126) ex-tend from the device site pads to the ring patterns, with a series of vias (210) making surface connections adjacent to the ring pat-terns. Engineering changes are made by directly writing surface metal deposits to make the appropriate connections between the vias and the ring pattern. The original chip pad connections (28, 29) and the new ring pattern (43) connections can be appropri-ately isolated by laser deletions, if necessary.

Title: Two-wire multi-channel streamer communication system
Inventor: ROUQUETTE ROBERT E
IPC: G01V1/22
Filed: 1993-01-19
Granted: 1998-08-25
Abstract: For use with marine seismic streamers, a two-wire, multi-channel communication system capable of handling the high throughput necessary for effective communication between a central controller aboard a tow vessel and the many sensors deployed along the streamer.  The central controller includes an intelligent modem with the capability of transmitting and receiving frequency-modulated message signals on one or more signal lines, such as conventional twisted-pair wires, over a number of individual inbound and outbound frequency channels.  In the preferred embodiment, seventeen channels are spread over a frequency band ranging from about 20kHz to 100kHz, thereby making available for communication a bandwidth much wider than available in conventional single-channel streamer communication.  In this way, many positioning sensors, such as compasses, depth sensors, cable-leveling birds, and acoustic-ranging transceivers, attached to the streamer and each having a transmitter and receiver tuned to one of the modem's inbound and outbound channels, respectively, can be put in communication with the modem.  To take advantage of its high throughput capability, the intelligent modem refers to a stored table of individual sensor parameters, such as sensor type, transmit channel, and receive channel, to schedule an efficient scan of the sensors.  As a diagnostic tool, the communication system also monitors the quality and performance of the communication link by measuring and recording such parameters as the transmitted and received signal strengths, signal-to-noise ratios, and number of incorrectly received messages.

Title: Gripper for a conveying device for conveying single-sheet or multi-sheet printing products
Inventor: EBERLE JUERG
IPC: B65H29/04
Filed: 1993-12-01
Granted: 1999-09-14
Abstract: The gripper (10) has two gripper parts (11, 13), of which the one, first gripper part (11) is pivotable relative to the other, second gripper part (13). For securely holding a printing product (P), the free ends (12a, 14a) of the two gripper parts (11, 13) interact. The first gripper part (11) is mounted by means of a ball joint (22) in a bearing part (21), which is seated unrotatably on a rotatably mounted hollow shaft (17). Between the bearing part (21) and the first gripper part (11), spherically mounted in the latter, there is arranged a compression spring (27), which in the closed position of the bearing part (21) exerts a compressive force on the first gripper part (11). The ball joint (22) is offset rearwards with respect to the pivot axis (17') of the bearing part (21). As a result, a lengthening of the leg (12) of the first gripper part (11) rearwards is attained, which results in more favourable leverages and, with a given compression spring (27), accordingly results in higher clamping forces at the free end (12a) of the first gripper part (11). The ball joint accommodates tilting of the first gripper part (11) so that it can accommodate printing products which vary in thickness in the width direction.
