Patent CA-2309839-A1 (CA)
Title: Shock absorbing carpet system
Inventor: KANTER RAY D
IPC: B32B5/18
Filed: 1998-11-17
Abstract: A carpet mat assembly (1) with shock absorbing properties includes a mat (2) made of closed cell foam sections. The mat sections (2) are sized to be readily portable, preferably 4ft by 6ft in size. The mat (2) thickness is selected to conform to ASTM F 1292-96. Preferably, the mat (2) thickness is 1 1/8" thick. The mat (2) section is coated with a pressure sensitive adhesive (4) covering on one side (3) of the mat (2). The pressure sensitive adhesive (4) is covered with a removable liner. The liner is removed to expose the pressure sensitive adhesive (4). Carpet (5) is applied to the coated surface of the mat (2) and the pressure sensitive adhesive (4) bonds the carpet (5) to the mat (2). The outer perimeters (7) of each mat (2) may be lined with 3M  Velcro® (8) for attaching multiple sections (2) of the carpet mat assembly (1) securely together. On the outer perimeter (7) of mat sections (2) not joined to other mat sections (2), an edge molding (9) preferably made from the same closed cell foam, may be attached to the mat (2) with a contact adhesive, or by other means. The completed assembly (1) provides a floor or ground surface for playgrounds, schools, childcare centers, martial arts, gymnasiums or other areas where shock absorbing surfaces are required.
Patent CA-2311549-A1 (CA)
Title: Vapor/liquid contacting cyclone with secondary vanes
Inventor: STOBER BERNE KIM
IPC: F02M29/06
Filed: 1998-11-06
Abstract: This invention is directed to a cyclonic vapor/liquid contacting device, and distillation or related mass transfer or heat transfer processes employing its use, such as fluid catalytic cracking. Liquid feed is introduced near the floor of the cyclone via the downcomer or plenum. Vapor enters through sieve holes in the bottom of the cyclonic device. Near the floor are angled tabs or vanes that impart a spin to the vapor rising up through the floor. The tabs or vanes mix the liquid and vapor. The liquid is then thrown toward the cyclone wall where it exits through slots in the wall.  A second set of tabs or vanes, located about in the middle of the cyclone, imparts additional spin to the vapor and entrained liquid rising through the cyclone.  This improves liquid collection by the cyclone, especially in cases where a heavy liquid load dampens the spin action of the vapor in the base of the cyclone.  In another embodiment, there is a non-spinning zone at the floor of the cyclone barrel which permits improved heat transfer between the liquid and vapor. If a non-spinning zone is used, the two sets of vanes or tabs are located at higher elevations within the barrel.

Filed: 1999-05-26
Abstract: A GSM mobile communicaton network comprising a group of picocells (2) or microcells within the coverage (11) of a simulcast carrier is arranged to instruct a mobile station (4, 4') to transmit on a BCCH frequency and the corresponding freed timeslot available to the picocellular heads (1) or to a base transceiver station is utilised to make interference measurements to assist in frequency allocation between the cells of the network or to enable all the picocellular heads to make uplink measurements on a mobile station to determine the best picocell for intercellular handover. This latter mode of operation overcomes the problem of frequency ambiguity associated with conventional downlink measurements by the mobile stations prior to handover in a simulcast system.

Title: Sensing ear temperature, acoustic reflectance and chemical components in the ear
Inventor: KIMBALL SANDRA
IPC: A61B8/00
Filed: 1999-10-20
Abstract: A device provides an indication of a condition of an ear by combining measurements of temperature in the ear, acoustic reflectance of the ear, and/or a characteristic of any fluid in the ear. Any two of these measurements may be combined in the same device to provide improved diagnostic information.  For example, chemical sensing of fluid may be combined with acoustic reflectometry or temperature sensing, or both, to provide improved diagnosis of ear pathologies. Acoustic reflectometry also may be combined with temperature sensing. Chemical sensing determines a characteristic of the fluid, such as whether a bacterium or a virus is present. The device may provide diagnostic information from sensed characteristics of the fluid, measured acoustic reflectance and/or measured temperature to indicate the risk of an ear infection. For example, the device may determine if any fluid present is infected. The device also may identify bacteria in the fluid. The temperature sensor also may be used to improved alignment between the device and the tympanic membrane, thus improving the accuracy of measurements.

Abstract: A panel hinge system for the joining, of two panels is disclosed. More specifically, the panel hinge system permits two panels to remain butted to each other such that the edges of the two panels are in constant contact, but without any direct material connection at their virtex. The panel hinge system has a hinge consisting of a series of levers pinned into a double parallelogram, such that there is no pin at the spatial fulcrum point where the panels are butted together. The double parallelogram ensures that the two panels revolve around and remain in contact with the spatial fulcrum. Therefore, two panels can assume an angle of 180 degrees or less without a visible seam or gap.
