Patent CA-2090707-C (CA)
Inventor: GLADSTEIN LEO ALBERT
IPC: G01R31/36
Filed: 1993-02-23
Granted: 1998-04-28
Abstract: A digitizer tablet computer has a host processor connected to a service processor which,  in turn,  is connected to a digitizer   controller  and   to   a   power   subsystem microcontroller.  A battery supplies the primary power for operating the computer but the computer is also connectable to an external source of DC power to charge the battery and to operate the computer when it is not running on battery power. The service processor includes a battery gauge the contents of which indicate how much power is left in the battery and how much time remains at the current rate of power consumption before the power runs out. The amount of remaining power in the gauge is determined by keeping track of power consumed, power added,  and power lost during off periods.  The use of the  second derivative  of a voltage versus  time  discharge  curve  creates  a point  from which relative accurate estimates can be made of how much longer the computer can be operated.

Title: Techniques to improve the performance of electrochemical sensors
Inventor: JOHNSON KIRK W
IPC: G01N27/327
Filed: 1993-11-17
Granted: 2004-07-20
Abstract: A method of improving the utility of electrochemical glucose sensors by decreasing either or both their settling time and their sensitivity to interfering compounds. In particular, the settling time of an electrochemical glucose sensor is improved by pretreating the operating electrode with a negative electric current at a constant current density. The sensor's sensitivity to intefering compounds is reduced by operating the sensor at a reduced voltage while the glucose concentration measurement is being made.

Title: Apparatus and method for depositing particulate material in a composite substrate
Inventor: VAN EPEREN THOMAS WILLIAM
IPC: A61F13/53
Filed: 1994-07-12
Granted: 2004-02-10
Abstract: An apparatus and method for forming a discrete layer of particulate material within a composite fibrous web includes a first forming chamber and a supplying mechanism for providing a flow of a selected fibrous material into the first forming chamber. A second forming chamber is selectively located within the first forming chamber to selectively divide the flow of fibrous material. A conveying mechanism transports a particulate material into the second forming chamber. A depositing mechanism is located within the second forming chamber to selectively dispense the particulate material. A foraminous forming layer is movably disposed within the first forming chamber and receives the fibrous material and the particulate material. As the foraminous forming layer moves, a first fibrous layer is formed on the foraminous forming layer, the particulate material is selectively deposited on the first fibrous layer, and a second fibrous layer is formed on the particulate material thereby providing the discrete layer of particulate material within the composite fibrous web. The depositing mechanism can be configured to dispense the particulate material in a selected pattern. The depositing mechanism can also be configured to intermittently dispense the particulate material at spaced apart locations along a length of the composite fibrous web.

Granted: 2002-01-08
Abstract: A woven structure is described in which optical fibers are positioned and held in the structure in a manner to maximize their optical efficiency. The structure consists of non-optical fibers extending in both the warp and woof direction, the optical fibers are positioned in channels between supporting fibers in the warp direction.      Selected ones of the non-optical fibers in the warp direction may be electrical conductors. The structure is manufactured using conventional weaving equipment by positioning both the optical fibers and the non-optical warp fibers, and then weaving the woof fibers into place without causing micro-bends or discontinuities in the optical fibers. The structure is woven with the optical fibers positioned in zero warp. The woven grid-like mat can be coated with a protective material that either enables it to form a flexible sheet or a rigid, hard, grid-like mat which has aligned zero warp optical fibers embedded therein. The structure shown can be used to provide sensing, imaging or communications. It can be utilized for optical backplanes for opto-electronic systems or a housing for opto-electronic components. Several types of interconnects or connectors can be fabricated according to the present invention capable of interfacing with the woven structure in an array-based, optical or opto-electronic, active or passive interconnect/connector scenario. The invention may also be used in highly parallel, high performance computer systems and sensing systems.

Granted: 2004-08-10
Abstract: An improved file system and method for incrementally recording data on compact discs is disclosed. The improved file system and method employs compact discs physically formatted in accordance with the so-called Orange Book specification. Files to be stored are selected from time to time and are divided into packets. The packets are then recorded in a program area of the compact disc together with link, run-in and run-out blocks in a format compatible with the Orange Book rules for linking incrementally recorded packets. File linking information is also stored with each file. If desired, files may, but need not, be recorded in a form compatible with existing CD-ROM and drivers adhering to the ISO-9660 standard. As selected files are recorded, file and directory information are stored in a first storage area either in a host system or in a track of the compact disc in a double linked and highly efficient format. From time to time, and if desired, this information may be recorded in ISO 9660 format in a reserved first track of a session. This may occur upon closing the session, at some other time, or not at all.      Multiple sessions may be recorded on the same compact disc.
