Title: Variable Length Codeword Packer
Inventor: DEROVANESSIAN HENRY
IPC: H04N7/26
Filed: 1994-03-25
Abstract: A variable length codeword packer communicates codeword data in successive m-bit bytes. A binary sum is accumulated indicative of a total number of codeword bits received over time. A byte pointer is derived from at least one most significant bit of the binary sum. A bit pointer is derived from a plurality of least significant bits of the binary sum. A first data storage array has a plurality of m-bit first storage bytes and is responsive to the byte pointer for storing received codeword data in the first storage bytes. A second data storage array has a plurality of m-bit second storage bytes and is responsive to the byte and bit pointers for filling the second storage bytes with codeword data from the first data storage array. m-bit bytes of codeword data are output from each filled second storage byte to provide successive m-bit bytes of codeword data. The use of a multistage approach in packing variable length codewords substantially reduces the complexity as compared to single stage designs.

Title: Specifying contexts in callback style programming
Inventor: BLEWETT CHARLES D
IPC: G06F9/40
Filed: 1994-05-19
Abstract: Abstract Apparatus and methods for specifying contexts for machine-executable instructions. Modern graphical user interface systems employ the callback programming style. In this style, a system event handler responds to an event by executing application-level callback code and providing event information concerning the event as part of the context of the execution. The technique disclosed herein uses callback information names to specify the relationship between the event information and the execution context. The callback information names are defined globally, but represent the event information for a single execution of the callback code. Using the callback information names, it is possible to define the callback code in the function which adds the callback code to the graphical user interface system.

Title: Microwave-based point liquid level monitoring system
Inventor: BROWN DAVID P
IPC: G01F23/02
Filed: 1992-10-22
Abstract: A point liquid level monitoring system includes a sensor removeably mounted to a liquid level device. The sensor is designed to direct a microwave signal from a transmitter through a window in the liquid level device. In one embodiment, the microwave signal is reflected off a surface in the device opposite the window and collected by a receiver. In another embodiment, the microwave signal is collected by a receiver mounted onto a second window opposite the first window through which the microwave signal is transmitted. When liquid is present in the liquid level device at or above the level of the transmitter and receiver, the microwave signal is attenuated as it passes through the liquid. Sensor electronics compare the received signal to a predetermined threshold level and provide an output indicating the presence or absence of liquid at the transmitter/receiver level. The sensor can be easily installed or removed from the liquid level device without draining, depressurizing, or otherwise disturbing the operation of the device or attached fluid systems and, when installed, does not obstruct visually reading liquid levels in the device.

Title: Fiber optical monitor for detecting motion based on changes in speckle patterns
Inventor: NAFARRATE ANTONIO B
IPC: A61B5/11
Filed: 1992-12-04
Abstract: A fiber optic body motion monitor in which light (1) is transmitted through an optical fiber waveguide physically coupled to a body being monitored, and modal noise at the output of the optical fiber waveguide (2) is applied to a photodetector (5), filtered, rectified and analyzed to detect breathing and heartbeats.  Detection of breathing is performed by low-pass filtering the rectified and filtered signal, and adaptive thresholding of the low-pass filtered signal. A similar but separate technique is used to detect heartbeats. In one embodiment, reliability of detection is enhanced by reducing the number of speckles of light applied to the photodetector to approximately 50 %, thereby to maximize modal noise current. In another embodiment the photodetector (5) has two halves separately illuminated by approximately two-thirds of the light from the optical fiber waveguide (2). Outputs of the photodetector (5) halves are applied to the positive and negative inputs of an operational amplifier (61), whereby common mode noise is eliminated and modal noise current and therefore sensitivity of modal noise detection increased.

Patent CA-2137500-A1 (CA)
Title: Twin heated wiper blade refill
Inventor: KRSTEVSKI GOGA
IPC: B60S1/54
Filed: 1994-12-07
Abstract: Normally, wiper blades, in extreme weather conditions such as snow and freezing rain, the wiper blade is not capable of cleaning the windshield properly.  It leaves streak marks and ice buildup.  This happens because the wiper blade itself becomes frozen and hard resulting in poor windshield cleaning action.    In this invention, THE TWIN HEATED WIPER BLADE REFILL, the above problems mentioned are eliminated because of the following reasons:  The design of the twin blades helps clean the windshield much more effectively because when the blades swing up or down the first blade wipes away most of the elements on the windshield and the following second blade wipes away the remaining residuals.  It is important to mention that also the fact that they are heated, adds as another reason why they are very good for the extreme weather conditions.    Also in this invention, a heated air chamber exists in the wiper blade refill.  The heated air chamber will keep the wiper blades warm resulting in superior effective wiping action, in comparison to conventional non-heated wiper blades.  The heated air will keep the wiper blades warm and soft in order for them to do an effective cleaning of the windshield.  Holes (Fig 1, #6: heated air chamber outlets) positioned along the bottom of the wiper blade refill.  Between the twin wiper blades (Fig 1, #1 and #2: wiper blades), there will be heated air blowing onto the windshield  and the wiper blades at the same time.

Title: Lockable closure for a fuel tank filler pipe
Inventor: GRAVINO MARC C
IPC: B60K15/04
Filed: 1995-01-13
Abstract: The closure includes a base adapted to be screwed into a fuel tank filler pipe and having a fill opening normally closed by a hinged flapper which is opened when a fuel nozzle is inserted into the fill opening.  The base is shielded against being manually gripped and un-screwed from the filler pipe by a cover also having a fill opening and normally supported for free rotation on the base so that turning of the cover normally is in-effective to unscrew the base.  When a key is inserted into the cover, it couples the cover and the base for rotation as a unit and thereby enables the base to be unscrewed from the filler pipe.  The same key also is used to actuate a locking device for locking the flapper in its closed position.

Title: Sure-step
Inventor: BARON STEVEN R
IPC: G09F15/00
Filed: 1995-03-09
Abstract: A galvanized and welded wire structure used in conjunction with corrugated plastic for an upright sign display. It consists of a single longitudinal rod to which is welded two U-shaped wire appendages. The top U is welded with minimum overlap to the top of the rod and the bottom, inverted U is welded at a predetermined distance from the bottom of the rod. The upper U is inserted into the flutes found in the corrugated plastic and the bottom, inverted U is pushed into the ground by the installers' foot. This U structure allows the sign to be posted in a stable manner, providing flexibility against force, such as strong winds. The longitudinal rod is of a thicker galvanized wire than the U structure as it is the main support for the apparatus. The upper U-shaped wire is of a thickness consistent with the cores of commercially manufactured corrugated plastic. This invention results in a single apparatus requiring no tools for its application and no loose parts that can be lost or stolen. Because the wire is galvanized, it is resistant to rust and may therefore be used repeatedly.
