Patent CA-2256523-A1 (CA)
Inventor: HEEJA YOO-WARREN
IPC: C07K14/72
Filed: 1997-06-05
Abstract: The present invention provides a novel galanin receptor protein, the GalR2 receptor. Also provided are the nucleic acid sequences encoding this novel receptor protein as well as methods for using this protein and its nucleic acid sequence, and methods useful for developing and identifying compounds for the treatment of diseases and disorders in which galanin is implicated. The importance of this discovery is manifested in the effects of galanin, which include antinociceptive activity, smooth muscle contraction, cardiovascular activity, pituitary hormone release, cognition, and increased food intake.  Thus, this receptor protein is useful for screening for galanin agonist and antagonist activity for controlling these conditions.
Patent CA-2257189-A1 (CA)
Title: Delivery of short messages in a packet radio network
Inventor: HAUMONT SERGE
IPC: H04W4/12
Filed: 1998-04-01
Abstract: The invention relates to delivery of short messages to mobile stations and particularly to delivery of short messages in mobility-supporting packet radio networks that use a mobile communications network as an access network, to a dual-mode mobile station in a situation where the mobile station is not reachable in the packet radio network. The object of the invention is to minimize unnecessary signalling. The invention is based on the fact that parameters controlling the network elements are inserted into the signalling messages and a flag indicating the state of the mobile station is inserted into the home location register. In the method and radio network of the invention, the signalling messages may contain parameters by means of which 1) delivery of a short message through the secondary network is prevented, 2) information on the fact that an attempt was made to reach the mobile station but the attempt was not successful is sent to the node of the secondary network, 3) the node of the secondary network is prevented from informing the home location register of the mobile station of the attach of the mobile station to the network, 4) information is sent to the home location register on the fact that the mobile station cannot be reached through the primary network, and 5) information is sent to the gateway mobile switching center for short message service on the fact that the mobile station can be reached through the primary network even though the short message was delivered through the secondary network.

Patent CA-2284225-A1 (CA)
Title: High power laser devices
Inventor: MOORADIAN ARAM
IPC: H01S5/14
Filed: 1998-03-19
Abstract: In an apparatus and method for generating high power laser radiation, the geometry of the resonant laser cavity defines a fundamental spatial or transverse cavity mode. A gain medium is disposed within the resonant cavity and an energy source energizes the gain medium within a first volume. This causes spontaneous and stimulated energy emission to propagate in the gain medium in a direction transverse to the fundamental cavity mode. The transverse emission in turn optically pumps a second volume of the gain medium about the first volume. When the intensity of the emission is sufficiently high, inversion and gain are produced in the second volume. By optimizing the geometry of the cavity such that the fundamental cavity mode is coupled to both the first and the second volumes encompassing the first pumped volume, the transversely-directed energy of the first volume which would otherwise be wasted is instead captured by the fundamental beam, improving the overall power efficiently of the laser. When configured in an external cavity, the high-power laser of the present invention is especially amenable to frequency conversion of the output beam, as it provides beam intensities suitable for efficient nonlinear frequency conversion.

Title: Treadmill ergometer
Inventor: LECHNER HUBERT
IPC: A63B22/02
Filed: 1998-06-02
Abstract: The invention relates to a treadmill ergometer with one left and one right driven endless main belt (2, 3). The aim of the invention is to avoid incorrect measuring results or treatment resulting from the interaction which takes place between two main belts operating at different speeds when a subject steps into the middle area. To this end, two non-driven secondary belts (4, 5) are provided between said main belts (2, 3). If the subject enters the middle area of the inventive treadmill ergometer, he/she steps first on the non-driven secondary belt of the opposite side rather than the main belt of that side. This avoids the problems mentioned above. The secondary belts are driven firstly by the friction between the soles of the shoes and the belts (2, 3, 4, 5) with which they come into contact, and secondly by friction engagement between the main belts (2, 3) and the secondary belts (4, 5) in an overlapping area.

Abstract: A method for obtaining a report from a mobile station on the status of frames comprising an entire message transmitted to the mobile station is disclosed. First, a polling request is sent to the mobile station from a base station. A status report is then sent to the base station. The polling request specifies whether the mobile station should send the status report on a reservation basis (using a reserved frame) or on a contention basis (using an idle frame). The mobile station then transmits a bit map to the communication system to indicate which frames have been correctly received by the mobile station at the point when it received the polling request.
