Title: Remotely-operated self-contained electronic lock security system assembly
Inventor: ANDREOU DEMOS
IPC: E05B47/00
Filed: 1992-09-18
Abstract: The present invention provides for a locking mechanism for use in a door and the like. A remote handheld controller transmits coded signals to an electronic door lock. A sensor/receiver receives the signals and provides the signal to a processor which compares the coded signals against a predetermined stored signal. If the received coded signal matches the predetermined signal, then the processor generates control signals to actuate an electromechanical device, which acts solely along or about the locking axis, to enable or disable the locking latch. The user is then able to turn the door handle in a normal manner. The coded signals are comprised of two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.

Title: Head-mounted projection display system featuring beam splitter
Inventor: FISHER RALPH W
IPC: H04N5/64
Filed: 1992-04-20
Abstract: A head-mounted projection display system (20) featuring a beam splitter (30) displays a simulated environment to an observer (26) using a light-weight, low cost, head-mounted projector and a retro-reflective screen (32). The display system optically colocates the projector with the observer's eyes (27) for effective use of either curved or flat retro-reflective screens. High screen gain achieved by the head-mounted projection display system (20) makes inexpensive projector sources such as a cathode ray tube (37) feasible. An alternative head-mounted display system also incorporating beam splitters producing unlimited horizontal field of view but with limited binocular overlap while using multiple head-mounted image sources for each eye is described. A method of providing the head-mounted display system also is disclosed.

Title: Method of simulating an industrial process, and use thereof for testing the operation of a controller
Inventor: WILLAEYS DIDIER
IPC: G05B17/02
Filed: 1993-01-21
Abstract: An industrial process (2) is simulated in which the value of each physical magnitude P i characteristic of its state is varied at a rate of change V i that is a function of the state of control signals (3) emitted by an automatic controller (1), and which reports its state to said controller by means of state signals (4) which are emitted by sensors as a function of the values of the respective physical magnitudes that they monitor. For each physical magnitude P i, the time interval .delta.t i is determined during which the value of the physical magnitude can change without any of the sensors monitoring said physical magnitude P i changing state.      Thereafter the value of each of the physical magnitudes P i is updated by incrementing its value by the product of the corresponding rate of change V i multiplied by the smallest of the above-determined time intervals .delta.t.      Finally, after updating the sensors monitoring each of the physical magnitudes P i, a parameterizable length of time is allowed to elapse before repeating the method.      The simulation method is used for testing the logical operation and the timing of a controller, such as an industrial programmable controller.

Abstract: An expendable lining may be applied over the interior walls of a metal handling vessel for molten metal, e.g. a tundish. The expendable lining is usually applied over a relatively permanent, e.g. refractory brick, lining.

Title: Cardiac rhythm management device with automatic optimization of performance related pacing parameters
Inventor: SALO RODNEY W
IPC: A61N1/365
Filed: 1993-08-24
Abstract: A dual chamber cardiac pacemaker incorporating a microprocessor-based controller which is programmed to automatically establish an A-V interval at a value which provides optimum cardiac function but without the need for a special sensor for measuring cardiac function is described. The microprocessor is programmed to continuously monitor heart rate and variation in heart rate and only when the patient is stable, enter a parameter adjustment loop in which the pacemaker's A-V interval is incremented in several discrete steps and for each step, the corresponding average steady-state heart rate is measured and stored. When the A-V interval incrementation process causes that interval to reach a predetermined upper limit, the pacemaker's A-V interval is set at the value that corresponds with the minimum average heart rate to thereby maximize cardiac performance.

Title: Interchangeable process connection resistant to installation errors
Inventor: PETRICH WILLIAM E
IPC: F16L23/00
Filed: 1992-08-25
Abstract: An assembly for aligning and supporting an adapter flange for connecting fluid pressures to a pressure sensor body in place on the body and to keep the flange in an unsealed condition to prevent pressurizing the body and flange until installation of permanent fasteners. The support fasteners retain the flange spaced from the body sufficiently so that the flange will not seal. This will prevent accidentally pressurizing the flange and pressure sensor body until permanent fasteners have been installed.      The body and flange are shipped with at least one extra set of permanent fasteners different in length from the fasteners used on the flange to permit adding adapters for a process connection. When a different thickness adapter is used for process connection, only the correct length fasteners will be capable of being threaded into the threaded openings and also seal the flange or adapter.
