Patent CA-2206116-A1 (CA)
Title: Self-emission noninvasive infrared spectrophotometer with temperature compensation
Inventor: STERLING BERNHARD B
IPC: A61B5/1495
Filed: 1995-11-30
Abstract: This invention is a method and apparatus for monitoring glucose, ethyl alcohol, and other blood constituents in a noninvasive manner. Long wavelength infrared energy emitted by the person as heat is monitored and the infrared absorption of particular constituents in the blood is measured (114) at characteristic infrared absorption wavelengths (110) for those constituents.  The measurements are preferably synchronized (124) with systole and diastole of the cardiac cycle so that the signal contribution caused by veins and tissues may be cancelled when a ratio of the detected signals is taken. If no synchronization is provided, the spectrophotometer may measure the arterial, venous, and tissue constituent concentrations simultaneously. The internal "blackbody" energy level of an infrared emissions source such as a vascularized appendage is measured (300) and used to compensate temperature dependent effects in the concentration calculation. The internal energy level ratio is ratioed to the actual measured energy.

IPC: E04F21/18
Filed: 1997-06-26
Abstract: An apparatus illustrated in two embodiments assists a sole worker in the positioning and installing of ceiling panels, such as sheetrock, to ceiling joists. In the first embodiment, a panel is placed on an arm pivotably connected to a post firmly positioned between a floor and a ceiling. Upon the release of a lever, a pressurized gas cylinder causes the arm to lift the panel angularly into substantially horizontal orientation adjacent the ceiling joists. In the second embodiment a plate formed with a ramp portion extends at an angle to a bearing plate portion. The bearing plate portion is fastened to a ceiling joist with the ramp portion angled downward. A first edge of a ceiling panel is placed on the ramp and the oppositeedge of the ceiling panel is lifted by a worker so that the first edge is forcedupward on the ramp to rest on the bearing portion as the second edge is brought into a substantially horizontal position.

Inventor: EDWARD BRUCE
IPC: A63B69/36
Filed: 1997-07-04
Abstract: An apparatus for determining a speed of a projectile uses control logic and a single acoustic sensor connected to the control logic. The control logic includes a pulsing clock.  The control logic starts the clock upon receiving a first signal from the acoustic sensor and stops the clock upon receiving a second signal from the acoustic sensor.   The control logic converts pulses of the clock into a numeric value indicative of  speed based upon a preprogrammed distance measurement setting.  The numeric value can then be converted into miles per hour and displayed to the user.

Patent CA-2217659-A1 (CA)
Inventor: BROWN J ERNEST
IPC: C09K8/62
Filed: 1997-10-07
Abstract: The improved recovery of hydrocarbons from subterranean formations by hydraulically fracturing a subterranean formation is accomplished. Fracturing fluids using a viscoelastic surfactant fluid containing wormlike micelles are useful to improve recovery of hydrocarbons and limit the loss of fracturing fluid into the formation fracture face.  The invention further relates to novel fracturing methods useful for increasing hydrocarbon production, limiting connate water production, resisting fracturing fluid loss into the subterranean formation, and reducing the equipment requirements in mixing and pumping fracturing fluid. The action of micelles of surfactant in aqueous zones of the subterranean formation facilitates the flowback of increased amounts of hydrocarbons once a fractured well is placed back on production.

IPC: G06F9/44
Filed: 1998-03-18
Abstract: Systems, methods and computer program products enable framework building by interactively generating a framework corresponding to a design and editing the interactively generated framework to obtain a completed framework. The framework is displayed in various stages of construction or modification using a number of different views including a tree view, a graph view, a method view and an edit view. In addition, parts of the framework are identified as requiring completion, as completed, and as permitting completion. Still further, user methods and framework methods are differentiated. Help guided actions are provided and may be invoked to assist in the development process. Once the framework has been completed, it can be stored in a data model, and code can be generated from the completed framework. Finally, interfaces developed using conventional editors may be parsed and imported into the data model for later code generation. As a result of the present invention, code may be generated based on the completed framework and executed in a distributed computing environment.

IPC: H04N1/32
Filed: 1998-04-16
Abstract: A system and method for providing a status/confirmation report associated with a facsimile message transmitted by an originating facsimile machine over a telecommunications network. A local or first communication path is provided between the originating facsimile machine and a double dialer and a network or second communication path is provided between the double dialer and a point of presence associated with the telecommunications network. The facsimile message is routed over the local and network communication paths from the originating facsimile machine to the point of presence for subsequent transmission to a destination facsimile machine. After receipt of the facsimile message at the point of presence, the local communication path is disconnected while maintaining the connection of the network communication path. The originating facsimile machine is then caused to change from transmission mode to receiving mode and a status/confirmation report is generated and transmitted over the local and network communication paths to the originating facsimile machine.

Title: Drive circuits for a magnetic recording device
Inventor: MIYAKE SHIGEKAZU
IPC: G11B5/09
Filed: 1998-06-26
Abstract: A drive circuit for a magnetic recording device is provided in which the stray capacitance and stray inductance of the peripheral wiring of the drive circuit is reduced.  Also, the drive circuit increases the read/write frequency of data and the recording   density   of   the   magnetic   recording   device.          Specifically, the drive circuit contains a write driver, a read preamplifier,  a write predriver,  a read postamplifier,  and a current signal detecting circuit.  The write driver inputs write data and outputs a corresponding writing current to a write head to store information onto a magnetic disk.  The read preamplifier supplies  a bias  current  to  a  read magnetic  head to  sense information  stored  on  the magnetic  disk  and  amplifies  the information as output data.  The write predriver inputs a write data signal via a data signal line and a write mode signal and supplies the write data to the write driver based on the write mode signal.  The read postamplifier inputs the output data and a read mode signal and amplifies the output data to produce a read data signal based on the read mode signal.   The current signal detecting circuit inputs an external  current setting signal via the data signal line and generates a current value signal based on the external current setting signal.
