Title: Cell cap assembly having frangible tab disconnect mechanism
Inventor: SOUH JUNG HO
IPC: H01M10/05
Filed: 1997-02-27
Abstract: A cell pressure control system is disclosed, which includes a conductive frangible tab (20), which tears in response to a defined pressure. The frangible tab is affixed at one position (24) to a stationary member, such as a subassembly jacket (28), and at another position to a deflection member, such as the flip portion (12) of a flip-burst disk, which deflects in response to increasing internal cell pressure. When the pressure increases to a dangerous level, the deflection member exerts sufficient pressure on the frangible tab to cause it to break. When the tab breaks, the cell goes into open circuit, thus reducing the danger of continued pressure build up. If the cell's internal pressure continues to increase even after the pressure contact is opened, a second stage of the pressure control mechanism may be activated. Specifically, a pressure rupturable region, defined by scoring (14), in the deflection member will rupture and release the cell's internal pressure.

Patent CA-2255991-A1 (CA)
Inventor: HAMKINS ERIC P
IPC: F15B11/00
Filed: 1998-12-14
Abstract: A hydraulic fluid is supplied from a tank to a plurality of actuators by a variable displacement pump which produces an output pressure that is a constant amount greater than a pressure at a control input.  A mechanism senses the greatest pressure among the workports to provide a first load-dependent pressure and a second load-dependent pressure which is greater than the first load-dependent pressure when the pump operates a maximum flow capacity.  Each valve section includes a pressure compensating valve which controls the fluid flow to the associated actuator in response to a pressure differential between the metering orifice and either the first or second load-dependent pressures.  When the pump operates at maximum flow capacity, actuators connected to the valve sections in which the pressure compensating valve responds to the first load-dependent pressure receive the fluid flow on a priority basis as compared to the other valve sections.  Thus the system operates the priority actuators as normally as possible during a maximum pump flow situation by reducing the fluid flow to non-priority actuators.

Title: Method for producing custom fitted medical devices
Inventor: CLYNCH GEORGE S
IPC: G05B19/4099
Filed: 1997-01-08
Abstract: An improved method for producing a medical device, such as a prosthetic or orthotic structure is disclosed which makes the procedure more widely available at less cost. The method involves making a model of the body part for which a medical structure is to be manufactured using a conformable fabric impregnated with a settable resin.  The model may be prepared by a physician or prosthetist who has no direct access to an expensive digitizing scanner. The model is removed from the patient's body part and shipped to a scanning facility where a digitizing scanner is used to produce a digitized image of the model. The digitized image is shrunk to compensate for the thickness of the model and the digitized data file is preferably sent back to the physician or prosthetist who manipulates the digitized image using a customized software program to produce a modified data file. The modified data file is sent to the scanning facility where the modified data file is converted into control code for a machine which produces a mold used in the manufacture of the medical device. The mold may be manufactured at the scanning facility or the modified data file may be uploaded to the manufacturing facility which may manufacture the mold as well as the medical device. The method is also adapted for use in producing many other medical or anthropometric devices which requires a comfortable precision fit to the human body.  The advantage is making this valuable medical service more widely available at reduced cost, and more efficiently utilizing expensive equipment to reduce the unit cost of medical and anthropometric devices.

Title: Method and apparatus for synchronizing devices in an audio/video system
Inventor: LAMACCHIA SAM R
IPC: G11B27/034
Filed: 1998-03-19
Abstract: An audio-visual editing system includes a universal slave driver (USD) coupled between a timecode-producing device, such as a video tape deck, and a digital audio workstation (DAW). The USD includes a sample counter for counting the audio samples for each timecode frame, and a timecode reader to interpret the tape's location. An audio board of the digital audio workstation includes an identical sample counter. Both counters are driven from a common clock. A serial interface connection couples the digital audio workstation to the universal slave driver. One of the handshaking pins of the serial interface connection is used as a dedicated reset pin. When the dedicated reset pin is pulsed, the running sample counters in both the USD and DAW are set to a common value, typically zero. Resetting the sample counters at precisely the same time ensures that the DAW and the USD are operating in synchronization. Once the sample counters are set to a common value, an efficient, binary protocol may be executed over the serial interface to determine the timing relationship between the sample counters and the beginning of a frame of the off-tape timecode from the videotape/audiotape recorder. The DAW need then only refer to its own sample counter, and not to any timecode, to calculate a precise point to trigger playback.
