Patent CA-2273919-A1 (CA)
Title: Counter-rotating scanner
Inventor: STANFIELD JAMES M
IPC: G06K7/10
Filed: 1997-10-06
Abstract: A scanner and a method for scanning a beam along a path employ a housing (320) that defines a first cylindrical cavity (322). A ring gear (330) is disposed within the cylindrical cavity and affixed to the housing.     A beam (312) is generated from a fixed location relative to the housing. A drive disk (340) is disposed within the first cylindrical cavity. The drive disk defines a second cylindrical cavity (348) and has a first axis of rotation (315). The drive disk defines a first channel in communication with the beam. The first channel (346) has a first proximal end pivotally rotatable about an axis adjacent the fixed location. A scan disk is disposed within the second cylindrical cavity and has a second axis of rotation offset from the first axis of rotation. The scan disk defines a second channel (366). The second channel has a second proximal end (374) in communication with the first distal opening (354). A spur gear (332), affixed to the scan disk, engages the ring so that the drive disk rotates in the first direction, the spur gear is displaced along the ring gear (330), thus causing the scan disk to rotate in a second direction opposite the first direction causing the second distal end to reciprocate. The beam is coupled through the first channel and the second channel and out of the second distal opening toward the path, thereby causing the beam to scan along the path as the second distal end reciprocates.

Abstract: A device which measures individual employee usage of a liquid product or hand soap dispenser as part of an overall hygiene compliance program. The dispenser consists of a self-contained keypad/display module which is attached to a standard hand soap dispenser. An employee enters a unique personal ID code and then activates the dispenser. The dispenser counts all inputs to the dispenser in order to generate meaningful data for management. Alternatively, the dispenser may only track and report total usage and not account for individual employee usage.

IPC: E04H15/42
Filed: 1999-07-16
Abstract: An improved tent (10) for quick construction, including a fabric enclosure (11) which serves as walls (28, 30, 32), roof (34) and floor (36) of the tent (10). The tent (10) includes a frame (12), which attaches to and supports the fabric enclosure (11). The frame (12) includes at least two frame poles (13) having upper (20) and lower ends (22).

The first component of the bicomponent fibers has a melting point which is at least about 50 °C lower than the melting point of the second component. The bonded carded web has a plurality of interfiber bonds. The web also contains a binder at a level of from about 10 to about 50 percent by weight, based on the weight of the bonded carded web, in which the amount of binder at the second side is less than the amount of binder at the first side and the amount of binder at the first side is sufficient to permit multiple attachments of the first side of the bonded carded web to and releases from the hooks without significant distortion of the fibers at the first side.

Title: Receiver having a tuning circuit with a selectable input
Inventor: OHIRA KOJI
IPC: H04N5/44
Filed: 1999-08-03
Abstract: A receiver includes two input terminals. A VHF broadcast signal over a 6-MHz band channel is inputted through one input terminal, while an FM broadcast signal over an approximate 100-kHz band channel is inputted through the other input terminal. The other input terminal is connected'with a trap circuit for band width reduction. This trap circuit causes attenuation in signal components over channels close to a desired channel except that over the desired channel with a band of approximately 100 kHz. An analog switch inputs selectively the VHF broadcast signal and the FM broadcast signal attenuated in the signal components to a tuning circuit having a tuning band width of approximately 6 MHz. When an FM broadcast signal is selected, an FM broadcast signal only over a desired channel is outputted from the tuning circuit.

Inventor: VINOGRADOV VALENTIN ANTONOVICH
IPC: A61P11/00
Filed: 1998-04-29
Abstract: A method of providing halotherapy to the upper portion (22-26) of the lower respiratory tract (20) includes the steps of operating a dispenser (30) and inhaling. The dispenser (30) contains a dry sodium chloride powder. The user operates the dispenser (30) to release a dosage of the powder for inhalation when the dispenser (30) is aimed into the user's mouth. The user then inhales the dosage of powder through the mouth. Because the powder has a particle size range enabling the powder to target the upper portion (22-26) of the lower respiratory (20) tract without entering the user's lungs, the dosage of the dry powder provides a concentration at the upper portion (22-26) sufficient to provide effective halotherapy. The preferred particle size range is from about 5 microns to about 20 microns. The preferred dosage is about 3 milligrams of powder.

Abstract: Disclosed is an all waveguide fiber wavelength converter which makes use of modulational instability to convert signal wavelength over a conversion bandwidth while maintaining a low pump laser power relative to other wavelength conversion devices such as those which make use of four wave mixing. The device is operated in the anomalous dispersion regions of the waveguides and the zero dispersion of the waveguide in which conversion occurs is less than the pump wavelength so that conversion may occur for signal wavelengths above and below the zero dispersion wavelength. Conversion efficiency is in the range of 25 dB to 30 dB.

Title: Method and apparatus for defining and updating mobile services based on subscriber groups
Inventor: LAIHO KEIJO TAPIO
IPC: H04W4/16
Filed: 1998-09-15
Abstract: New services and/or new subscribers are efficiently and flexibly defined and added to a mobile communications network using service groups and service group identifiers. One or more groups of mobile subscribers are defined, and a group identifier is assigned to each member of the group.  One or more services are established for the group of mobile subscribers and are associated with the group identifier. In particular, the group identifier links each member of the group with the established services. Using this service group approach, existing mobile communications system nodes are readily updated with new service and subscriber information. Likewise, subscriber service information may be easily restored to corrupted mobile databases. Advantageously, the signaling and time required to perform location update procedures as mobile units move between different location areas in a mobile communications system are consider-ably reduced.
