Patent CA-2268424-A1 (CA)
Title: Method and apparatus for allocation of a transmission frequency within a given spectrum
Inventor: LUCIDARME THIERRY
IPC: H04L1/00
Filed: 1999-04-09
Abstract: A method of allocating a transmission centre frequency for a candidate transmission within a frequency spectrum available for communications within a telecommunications system is described, the candidate transmission having a power/frequency characteristic representative of the power of the candidate transmission as a function of frequency. The method includes providing a power spectrum representative of the cumulative effect of the power/frequency characteristics of at least a portion of the existing transmissions at a plurality of centre frequencies within the frequency spectrum at the time of allocation and evaluating allocation decision values defined by a first function of the power spectrum and the power/frequency characteristic of the candidate transmission.  The centre frequency for the candidate transmission is selected from the frequency spectrum based on a minimum value among the evaluated allocation decision values or based on an evaluated allocation decision value being below a first threshold value.  The first function is preferably indicative of the interference of the existing transmissions on the candidate transmision. Preferably, the selection of a suitable centre frequency is only carried out if the value of a second function of the power spectrum and the power/frequency characteristic of the candidate transmission is below a predetermined value. The second function is preferably indicative of interference of the candidate transmission on the existing transmissions. A control element for controlling a transceiver in the telecomunications system is also described.

IPC: G06F19/00
Filed: 1998-09-18
Abstract: The present invention is an integrated system of collecting data, reporting results, enabling an understanding of weight control, and weight loss. The first embodiment of the invention is for a method of estimating an individual's baseline normal activities calories. The second embodiment of the invention is a method for the individual to plan (112), and forecast (114) weight loss goals. The third embodiment of the invention enables the individual to record estimates of weight, food calories, and exercise calories constructing his own weight loss database. The individual's calories density (110) is measured, is used to increase plan (150), and forecast accuracy. A graphical representation of the data enables the individual to detect body water shifts, weight plateaus, and resting metabolic rate changes so as to enable the individual to know the reasons why the individual is losing or not losing weight. The system organizes the data to minimize the impact of errors in the data while maximizing the data's information value. The system uses the individual's own body in a closed loop approach as its own calorimeter.

Le procédé selon l'invention permet de créer des codes d'identification C courts et relativement simples à déterminer, présentant une sécurité de reconnaissance élevée pour une pluralité d'applications.
Patent CA-2297391-A1 (CA)
Inventor: BAKER GERALD
IPC: F16K17/164
Filed: 2000-01-28
Abstract: A valve actuator with an emergency shutdown feature incorporates shutdown of the valve when a sensed line pressure is outside of high- and low-pressure trip points. The actuator can be manually tripped. The actuator can be tripped in the event of a fire or, incorporating a solenoid, a trip can be accomplished with an appropriate signal. Once tripped, the actuator requires manual reset. The normal open and closed operation of the valve cooperates with a clutching mechanism which is part of the trip system. The preferred embodiment of the clutching system is a torsion spring or springs which normally allow movement in one direction but not in the other unless acted upon by the tripping system.
