Title: Connector and method for sealed pass-through of insulated electrical conductors
Inventor: STANEVICH KENNETH W
IPC: H01B17/58
Filed: 1992-02-14
Granted: 1995-07-18
Abstract: The invention provides a connector for passing continuous insulated electrical conductors such as pins or multi-stranded wire through a surface or bulkhead, while preventing leakage of liquids and gases along the conductors, especially between gaps in  the  strands.   An  exemplary  connector  of  the  invention comprises a body having seal-zone openings in which a sealant is applied to and cured around a compressed bared section of multi-stranded wire.  The body contains strain relief members adjacent to the sealed openings to provide longitudinal as well as  transverse  strain  relief.   A sealant member  and  radially spaced clasps are located around the sealed openings and strain relief  members  so  that  the  connector  may  be  removably twist-locked  onto  a  bulkhead  without  disturbing  the  sealed wires.   The  invention  also  provides  a  method  for  achieving  the sealed pass-through of electrical conductors.

Title: Method and apparatus for distinctively displaying windows on a computer display screen
Inventor: BATES CARY LEE
IPC: G06F3/033
Filed: 1992-08-06
Granted: 1997-01-21
Abstract: A method and apparatus for distinctively displaying windows on a computer display screen is disclosed.  The amount of time each of the windows presented to the display screen is active (also known as "in focus") is monitored. Upon receipt of a command from the user, the windows that were active a longer length of time are displayed more distinctively than windows that were active a shorter length of time. Active windows can be displayed more distinctively in many different ways. One such way is by placing the most active window in the upper left corner of the screen and placing the rest of the windows in a descending order of activity from left to right and top to bottom on the screen. Another way is to cascade the windows, where the windows are cascaded in a descending order of activity from the front to the back of the window stack.  Yet another way is to generate a list of window titles associated with each window, in a descending order of activity from the top of the list to the bottom of the list.  Still another way of distinctively displaying more active windows is to put the most active window in focus, and then put the remainder of the windows in focus in descending order of activity in a toggle sequence of windows.

Title: Fast response matched filter receiver with decision feedback equalizer
Inventor: YAMAMOTO TAKESHI
IPC: H04L25/03
Filed: 1992-09-28
Granted: 1996-11-12
Abstract: A tap-weight controller of a matched filter includes a tapped delay line having a series of delay elements for receiving an incoming digital signal to produce successively delayed signals at successive taps of the delay line so that the signal at the center tap coincides with the output of a decision feedback equalizer (DFE). Correlation circuits are provided corresponding respectively to tap-weight multipliers of a transversal filter and to the taps of the delay line of the tap-weight controller. In each correlation circuit, correlation is detected between the output of the DFE and a signal from the corresponding tap of the delay line, and a signal indicating the detected correlation is integrated over a prescribed interval. An adder has a first input for receiving the detected correlation signal and a second input for receiving the integrated signal or a tap-weight control signal to produce a summed signal. The correlation signal is delayed for an interval equal to the prescribed interval and subtracted from the summed signal to produce an output which is applied to the adder as the tap weight control signal as well as to the corresponding tap-weight multiplier. The integrated signal is initially applied to the second input of the adder, and thereafter, the tap-weight control signal is applied to the adder to update the control signal at symbol intervals.

Title: Non-contact tamper sensing by electronic means
Inventor: GRITTON DALE GROVER
IPC: G06F21/86
Filed: 1992-11-17
Granted: 2001-06-12
Abstract: A tamper-sensing system for an electronic tag 10 which is to be fixed to a surface 11 of an article 12, the tamper-sensing system comprising a capacitor having two non-contacting, capacitively-coupled elements 16, 19.      Fixing of the body to the article will establish a precise location of the capacitor elements 16 and 19 relative to each other. When interrogated, the tag will generate a tamper-sensing signal having a value which is a function of the amount of capacity of the capacitor elements. The precise relative location of the capacitor elements cannot be duplicated if the tag is removed and affixed to a surrogate article having a fiducial capacitor element 19 fixed thereto. A very small displacement, in the order of 2-10 microns, of the capacitor elements relative to each other if the tag body is removed and fixed to a surrogate article will result in the tamper-sensing signal having a different, and detectable, value when the tag is interrogated.

Abstract: A method and apparatus for analyzing chemical species includes an ion source (2) at or near ambient pressure and a time-of-flight mass spectrometer which receives the ions, created at the ion source (2) through an ion supersonic jet forming device (5, 6). The ion source (2) creates ions from neutral molecules in the sample to be analyzed or serves to introduce already formed ions into the mass spectrometer vacuum chamber (11). The ion source can use any of the known techniques for ion creation, including a corona discharge (3) or a 63 Ni Be-ta ion source (22). The ions are created and are then in-troduced into the vacuum region (11) of the mass spec-trometer through a small orifice (6) which causes the stream of ions entering the vacuum region (11) to enter as a supersonic jet wherein the kinetic energy of each in-dividual ion falls within a narrow energy band. The ions are then repelled or drawn into the field-free flight tube of the mass spectrometer and separated and identified based on their mass-to-charge ratios.

Title: Pacemaker telemetry system
Inventor: RYAN TERRENCE G
IPC: H04L25/49
Filed: 1994-05-10
Granted: 2001-04-24
Abstract: An implantable medical device telemetry system provides a means for decoding telemetry downlink information transmitted from an external unit to an implanted medical device, and for encoding telemetry uplink signals to be transmitted from the implanted device to the external unit. A novel system architecture results in a very small telemetry subsystem in the implanted device and a very flexible system adaptable to be used in conjunction with various telemetry formats of various implanted devices. A programmable logic array (PLA) structure that is mask programmable and which may further be partially RAM programmable serves as the basis of the telemetry subsystem For downlink telemetry, a counter is enabled during intevals of interest in the downlink RF burst stream. The counter value at the end of such an interval is then applied to the variable inputs of the PLA for decoding in accordance with a selected telemetry protocol. For uplink telemetry, the counter and PLA is used to control transmission of uplink telemetry pulses, such that pulses are pulse-position modulated in accordance with data to be transmitted. Various different telemetry protocols may be supported by the same telemetry circuit, which may be mask-masked at the time of manufacture to be compatible with one or more different telemetry protocols.
