Patent CA-2200508-A1 (CA)
Title: Security for Controlled Access Systems
Inventor: BULFER ANDREW FREDERICK
IPC: H04L29/06
Filed: 1997-03-20
Abstract: In order to gain access to a secured system, a user must be able to enter valid user identification information and must also have a remote wireless communication device such as a pager or cellular telephone having a number that is substantially unique to that user. When the user requests access to the secured system, the system places a call to the user's remote wireless communication device and sends that device revalidation information such as a random number generatedby the secured system. The user must return the revalidation information to the secured system to gain access. In an alternative embodiment, another person (a user-approver) has the remote wireless communication device and must return the revalidation information to the secured system if the user-approver approves theuser's request for access.

Title: Exposure indicator with alarm signal
Inventor: PARSONAGE EDWARD E
IPC: A62B18/02
Filed: 1995-09-11
Abstract: An exposure indicating apparatus having a sensor with at least one property responsive to a concentration of a target species within an environment. A processing device generates a concentration signal as a function of the at least one property. The exposure signaling rate varies as a function of the concentration signal. Alternatively, the processing device may provide a threshold detector for generating a i threshold signal in response to the concentration signal when a predetermined threshold concentration is attained. The exposure signaling rate may then vary thereafter as a function of the concentration signal. The processing device drives the indicator at a ready signaling rate indicative of an exposure indicating apparatus operating within predefined design parameters and a fault signaling rate different from the ready signaling rate indicative of the exposure indicating apparatus operating outside of the predefined desing parameters. The indicator operates at a signaling rate in the frequency range of 0.001 to 30 Hz.

Filed: 1996-11-27
Abstract: A vehicle computer system has a housing sized to be mounted in a vehicle dashboard or other appropriate location, a computer mounted within the housing, and an open platform operating system which executes on an open hardware architecture computer. The open platform operating system supports multiple different applications that can be supplied by a vehicle user. For instance, the operating system can support applications pertaining io entertainment, navigation, communications, security, diagnostics, and others. The computer has one or more storage drive (e.g., CD drive, sloppy disk drive, cassette player, or hard disk drive) which permits the vehicle user to download programs from a storage medium (e.g., CD, diskette, cassette, or hard disk) to the computer. In the described implementation, the computer has two independent processors. One processor, which runs the operating system, is mounted in a stationary base unit of the housing and the other processor is mounted to a faceplate which is detachable from the base unit. When the faceplate is attached, the first processor provides the primacy control over all operating systems (i.e., entertainment, navigation, communications, security, diagnostics, and others) and the faceplate processor is subservient. When the faceplate is detached, it forms a portable RF device with the faceplate processor providing radio and communications capabilities.

Patent CA-2211863-A1 (CA)
Inventor: DING NI
IPC: B05D7/02
Filed: 1996-01-15
Abstract: A process for preparing coating compositions of a commingled hydrogel of a polyurethane-polyurea polymer hydrogel and a poly(N-vinylpyrrolidone) polymer hydrogel; a process for making materials composed of a polymeric plastic or rubber substrate or a metallic substrate, with a coating of the commingled hydrogel thereon; and a process for making medical devices with a coating of the commingled hydrogel thereon, are disclosed. The coating compositions tenaciously adhere to the substrate materials and medical devices to which they are applied due to bonding of a tie coat to a reactive substrate surface and due to the commingling of the two hydrogel components. The coating compositions and coated materials and medical devices are non-toxic and biocompatible, making them ideally suited for use in applications such as for catheters, catheter balloons and stents. In such applications, the coating compositions, coated materials, and coated medical devices made therefrom demonstrate low coefficients of friction in contact with body fluids, especially blood, as well as a high degree of wear permanence over prolonged use. The commingled hydrogel coatings are capable of being dried to facilitate storage of the devices to which they have been applied, and can be instantly reactivated for later use by exposure to water.

Title: Apparatus and method for recovering non-ferrous metals from hot dross
Inventor: ZEBEDEE WILLIAM A
IPC: C22B21/00
Filed: 1995-12-27
Abstract: Method and apparatus for recovering free aluminum from a metal bearing dross containing free aluminum metal and oxides of the metal. Hot dross (14) is collected from a hot dross source (10) into a vessel (12), and the vessel (12) is placed into a sealable storage container (18). The storage container (18) is insulated to maintain heat generated by the hot dross within the interior of the storage container to maintain the dross at or near its temperature when first placed in the storage container. An inert gas is then introduced into the container to purge the container (18) of all gases other than the inert gas. The inert gas reduces thermiting of the hot dross and limits the cooling of the hot dross in order to maintain the hot dross at an elevated temperature while the hot dross remains in the storage container (18). The dross (14) is then removed from the vessel (12) and introduced into a dross processing device (26) such as a furnace.

Title: Catalyst for purifying exhaust gas and a process for purifying exhaust gas
Inventor: HORIUCHI MAKOTO
IPC: B01D53/94
Filed: 1997-04-09
Abstract: An exhaust-gas-purifying catalyst is made by depositing on a support iridium serving as a catalyst active substance, sulfur for improving the catalyst activity of iridium and, if necessary, platinum. The sulfur is preferably contained as a sulfate. The exhaust-gas-purifying process of the present invention is a process in which exhaust gas from an internal combustion engine is allowed to pass through the exhaust-gas-purifying catalyst with the exhaust-gas temperature being set in the range of 200°C to 700°C at the inlet of the exhaust-gas-purifying catalyst. The above-mentioned composition and process provide an activity for purifying exhaust gas, especially for eliminating nitrogen oxides in an oxidizing atmosphere, in a wide temperature range, allow high heat-resistance and durability, and consequently, are superior in practical use.

Title: Image encoding apparatus, image decoding apparatus, image encoding method, image decoding method, image encoding program recording medium and image decoding program recording medium
Inventor: KADONO SHINYA
IPC: H04N19/593
Filed: 1997-05-15
Abstract: Image signals or shape signals are encoded more efficiently than conversion techniques. A changed-picture element detector (2) receives an input signal (1) and detects such a picture element that changes in binary picture element value. A changed-picture element predictor (4) reads a reference image stored in a memory (3) and predicts changed picture elements of the input signal (1).  A differential value calculator (5) subtracts the output of the predictor (4) from the output of the detector (2) and a differential value rounding device (7) compares an allowance value (e) with a predicted error (D) and outputs a minimum value (x) (D-exD+e) at which the number of bits required for the encoding using the value (x) becomes the smallest. An encoder (8) encodes the output of the device (7) into an encoded signal (9) and a differential value adder (11) calculates a changed-picture element by adding the output of the device (7) to the predicted picture element predicted by the predictor (4). A  changed-picture element decoder (10) decodes each picture element value from the decoded picture elements specified by the predictor (4) to the changed-picture elements and stores the decoded picture element values in the memory (3).
