Title: Mobile telephony
Inventor: MEAD ANDREW ROBERT
IPC: H04B7/185
Filed: 2000-08-10
Abstract: A movable switching system provides cell, or small network of cells, which moves with the aircraft or other vehicle on which it is located, but whose operation appears to the user as an ordinary fixed base station of the "host"  network to which it is connected. A cellular mobile switching centre (116), on board the aircraft, detects a call attempt or registration attempt from a mobile unit (110) and generates a temporary onboard identity for association with the mobile identity code. The cellular identity is passed to a network registration unit (145) to allow a location update to allow calls to the cellular telephone (110) to be routed to the mobile station (141).  Consequently, any incoming calls intended for the mobile user will now be directed to the network (104), as the mobile user is currently registered there.

Title: Method for defrosting logs and a defrosting apparatus
Inventor: JONKKA ARVO
IPC: B27L1/00
Filed: 2001-06-29
Abstract: The present invention concerns a method and an apparatus for defrosting frozen wood prior to debarking. The defrosting method of logs of the invention is based on bringing heat zone-specifically to logs in transfer motion on a conveyor according to their heat receiving capacity immediately from the moment of starting of the defrosting, and at the end of the defrosting process, the heat volume per time unit, supplied at a higher temperature, is only a part of the heat volume of the starting phase of the defrosting process. For instance, it is possible to spray water on the wood to be defrosted so that the row interval of the showers in the initial part of the piping is a fraction of the row interval in the tail end of the piping. In the tail end of the defrosting conveyor steam can also be supplied.

Patent CA-2365572-A1 (CA)
Inventor: HARRISON CHRISTOPHER
IPC: G06F9/44
Filed: 2000-05-25
Abstract: A method and apparatus are provided for extending the behavior and attributes of applications designed using a fourth generation language (4GL) programming tool. Specifically, a 4GL programming tool is provided that allows application designers to specify the implementation classes of the components that are used in the applications that they design using the 4GL programming tool.  The implementation classes thus specified may define attributes and behaviors not supported by the corresponding component implementations provided with the 4GL programming tool. During runtime, methods in the specified implementation classes are invoked. To correctly invoke the methods of user-specified implementation classes, the interfaces of the methods must be known to the entity performing the invocations. Therefore, according to one aspect of the invention, all component implementations that are to be used by the application, including both the "standard" component implementations provided with the 4GL programming tool and the "custom" component implementations specified by the application designer, implement a common interface.

Title: Low-power radio frequency identification reader
Inventor: WATKINS RANDY W
IPC: H04B1/59
Filed: 2000-04-21
Abstract: Practical battery operation of radio-frequency proximity readers (12) in a tag reader system (10) is made possible by monitoring activity in the RFID reader's sensing field (S) with a secondary detector (20) such as a passive infrared detector having an overlapping field of view (V), and powering up the RFID  reader only upon detection of activity by the secondary detector. The RFID reader is kept to a low duty cycle relative to the secondary detector which is chosen for relatively low power consumption to achieve a net reduction in operating power requirements of the combined RFID reader and secondary detector.
