Title: Seat and seat belt sequence circuit
Inventor: SHOEMAKER JIM MILTON
IPC: B60R22/48
Filed: 1998-05-05
Abstract: A simple discrete component logic circuit with transistors selectively connectedthrough seat and belt switches to the battery. The transistors operate in either an off mode or a current saturation mode. The circuit includes a plurality of identical resistors and transistors for ease of assembly and reduced cost and can operate over a wide range of voltages without need for power regulation or filters. The circuit recognizes the proper logic sequence with the key switch in either the on or off position but an improper sequence warning signal is provided only after the key switch is turned on. The circuit prevents intermittent warnings or interruptions caused by the operator temporarily bouncing from the seat, but the proper sequence of operations must be preformed and the switches must be operational to prevent a warning signal.

Title: Method and apparatus for improving stuck-at fault detection in large scale integrated circuit testing
Inventor: CARR LARRIE SIMON
IPC: G01R31/317
Filed: 1998-04-09
Abstract: A bus holder for coupling to an integrated circuit bus driven by a plurality of tri-state devices. The bus holder has a bidirectional port and first and second test ports. Logic circuitry coupled between the respective ports is config-ured such that application of a logic 0 to the first test port causes the bidirectional port to drive whatever logic value is applied to that port; application of a logic 1 to the first test port and application of a logic 0 to the second test port pulls the bidirectional port down to a logic 0; and, application of a logic 1 to both the first and second test ports pulls the bidirectional port up to a logic 1.
Patent CA-2237972-A1 (CA)
Inventor: BANERJEE VIKRAM K
IPC: F41H11/136
Filed: 1998-05-19
Abstract: A two-step process for clearing unexploded ordnance ("UXO") from the ground. First a high power electromagnetic transmitter sweeps the ground area to be decommissioned. Secondly a lower-power time-domain electromagnetic transmitter or metal detector sweeps the same area to locate UXO. The high power transmitter employs a waveform of having the same frequency and pulse duration as that of the metal detector but does so with at least twice the power. Firstly, when the higher power waveform is applied to the ground, UXO which does not trigger and detonate or "function" is proved as non- functioning at subsequent and lower detection power. Subsequently, the ground area can then be safely scanned by human personnel with impunity, applying the more accurate, lower power metal detector. The detected locations of unexploded ordnance are recorded for subsequent manual removal.

Patent CA-2242180-A1 (CA)
Title: Telephone system
Inventor: COXON MARK CHRISTOPHER
IPC: H04W92/10
Filed: 1997-01-30
Abstract: During the registration process by which a connection is set up between a mobile telephone and a base station of a mobile telephone network the telephone acquires program data from the network for controlling its operation. This allows upgrades of the system to be provided automatically to the mobile telephone. The mobile telephone (1) and base station (10) each have a memory (7, 19) for storing program data relating to one or more modes of operation. During the registration process the base station (10) transmits a signal indicative of a preferred mode of operation. The mobile telephone (1) responds with a signal indicative of whether its memory (7) already contains program data for this mode of operation. If the signal indicates that the memory (7) does not have this program data, the base station (10) transmits the required program data to the mobile telephone (1). The base station (10) and mobile telephone (1) can then operate in this mode. A check is made to establish if the mobile telephone (1) is able to accept the data. If it is not so capable (for example because it has insufficient memory), the process is repeated with different programs until a program is identified for which there is sufficient capacity in the memory (7). If a call attempt is initiated before this process is complete, the process is curtailed, such that the base station (10) and mobile telephone (1) identify programs already stored in the memory (7), but make no attempt to load a new program, as this could delay call set-up. If the base station (10) receives no response to its initial indication of a preferred program, as would occur if it establishes contact with a conventional (non-programmable) mobile telephone, the base station (10) operates in a default mode.

Title: Emulation repair system
Inventor: NACHENBERG CAREY
IPC: G06F1/00
Filed: 1997-02-03
Abstract: An emulation repair system (200) restores virus-infected computer files (220) to their uninfected states without risk of infecting the rest of the computer system (202), by providing a virtual machine (216) for emulating the virus-infected computer file (220), a foundation module (240) including generic, machine language repair routines (242), and a virus specific overlay module (262). Emulation repair system (200) receives the identity of the infected computer file (220) and the infecting virus (224) from a virus scanning module, and uses the received information to access a virus definition (232) that includes decryption information on the identified virus (224). The infected computer file (220) is emulated in the virtual machine (216) until it is determined from comparison with the decryption information that the virus (224) is fully decrypted. The foundation and overlay modules (240, 262) are then loaded into the virtual machine (216) and control of the virtual machine (216) is given to the overlay module (262). The overlay module (262) calls repair routines in the foundation module (240), the overlay module (262), and the virus itself (224), as necessary, to restore over-written host bytes (228) from the infected host file (220) to their proper locations in the infected host file (220). Repairs made to the image (220") of the host file (220) in the virtual machine (216) are reflected to a back-up file (220') in the computer system (202).

Title: Cutter element with non-rectilinear crest
Inventor: MINIKUS JAMES C
IPC: E21B10/52
Filed: 1998-09-03
Abstract: A cutter element for a drill bit. The cutter element has a non-rectilinear crest. The non-rectilinear or curvilinear crest provides an advantageous distribution of the cutting forces across the body of the cutter elements and thus improves bit life. The curvilinear crest also allows the cutter element to more efficiently lift the portion of the formation that is being cut, thereby improving cutting action in certain formations. The cutter elements can have either positive or non-positive draft and can be tungsten carbide inserts.

Inventor: WESTERMANN GERHARD
IPC: G09F3/20
Filed: 1997-10-23
Abstract: The invention relates to a display cassette for an interchangeable information carrier with a carrier housing containing at least one partially transparent hinged lid which can swing open and an integrated compartment receiving an information carrier. The individual hinged lid can be lifted and swung shut and removed from the carrier housing. Said lid has an inspection glass to which side walls, with the exception of the upper front edge, are joined at least partially on three edges. When the display cassette is closed, the lid or at least sections thereof is encased in the area where both edges of its inspection glass run parallel to its pivotal axis, so that it is propped up at least partially with its upper front edge or another part of the front area against the carrier housing by means of an spring mechanism located between the lid and the housing. The travel of the spring is greater than the closing travel of the lid in the direction of support. Because of such a design the cassette is easy to handle and robust.

Title: Papermaking belt
Inventor: SAKUMA NORIO
IPC: D21F3/02
Filed: 1999-08-06
Abstract: In a one-surface coated papermaking belt composed of a base layer and a thick resin layer, or a covered, one--surface coated papermaking belt composed of thin and thick resin layers on opposite sides of a base layer, curling of the edges of the belt due to the shrinkage of the thick resin layer is reduced by forming the opposite side edge parts of the thick resin layer thinner than the middle part. The reduction in curling results in improved oil removal especially in a shoe-press belt. It also stabilizes turning of the belt and facilitates belt installation.
