Patent CA-2192182-A1 (CA)
Title: Noninvasive method and apparatus for determining resonance information for rotating machinery components and for anticipating component failure from changes therein
Inventor: HERNANDEZ WALTER C
IPC: G01M99/00
Filed: 1994-04-05
Abstract: A method and apparatus is described for determining resonant frequencies of vibration of turbine (20) and (22) and fan shafts (16) and blades, and other rotating machines (12) in which a rotating element of the machine (12) has oscillatory vibrations that modulate the fundamental frequency of rotation of the rotating machine (12). A sensor (30) monitors the machine (12), providing a train of sensor pulses or other signal representative of angular rotation of the machine (12). The signal is processed to provide a signal representative of the modulation of the fundamental frequency of rotation of the rotating machine (12), which signal is processed to provide a frequency spectrum representative of instantaneous-frequency components present. The signal spectrum is electronically processed to provide resonanceinformation, spectral signals representative of frequency or amplitude characteristics, or both, for the resonant vibrations. Signal-processing methods (36) include use of Fast Fourier Transform and Discrete Fourier Transform.

Patent CA-2194766-A1 (CA)
Inventor: BUTT JOHN
IPC: G06F9/50
Filed: 1995-07-19
Abstract: A network manager for a telecommunications network has a client-server architecture. The software components of the network manager include a set of clients (50) which form part of the application programs of the network manager, a user interface (32), a database (36) containing details of the network and a communications stack (38) for communicating with exchanges managed by the network manager. The clients (50) generate requests to run jobs on servers (52) and (54). The jobs which are run on server (52) are eventually destined for a resource in the form of a database (36), while the jobs which are run on servers (54) are eventually destined for resources in the form of exchanges. The requests are initially passed to software module JBM. This module then checks if the resource for which the job is destined is free and, if not, puts the job on a holding queue. If the resource is free, it checks whether the job is scheduled for immediate execution or execution at a future time. If it is scheduled for execution at a future time, it is put on a queue of scheduled jobs. If the job is scheduled for immediate execution, the module JBM checks if a server is free to accept the job. If no server is free, the job is put on a queue of jobs awaiting immediate execution. If the server is free, the module JBM instructs a module SMAN to load the job onto the free server.

Title: Method of displaying advertising messages
Inventor: MCCREARY RONALD KIM
IPC: B60Q1/30
Filed: 1997-07-09
Abstract: A message to be displayed is sent to the display device from an onboard processor, having been retrieved from memory. The message comes on with the automotive brake lights and remains on until the brakes are released. The message changes with each application of the brake lights and is a continuous loop of sequentially displayed messages. In an alternative embodiment, the display remains on in a dimmer mode until the next application of the brakes changes the message. Thus, the message may be displayed while brake lights are energized, or alternatively, once brake lights are extinguished the message goes to a tail light mode having a reduced illumination level, for example, half as bright.
