Patent CA-2418156-A1 (CA)
Title: Temperature compensation mechanism for lcd module in a time of flight ranging system
Inventor: PRESTON NIGEL ASHLEY
IPC: G01S7/04
Filed: 2003-01-31
Abstract: A temperature compensation circuit for a liquid crystal display (LCD) module. The temperature compensation circuit includes a thermistor which in response to changes in temperatures changes the clocking rate for the drive signals for the LCD module. A further bias voltage circuit may be included which in response to a change in temperature changes the bias voltage for the LCD module. The effect of the temperature variable clocking rate and/or bias voltage is to improve the segment contrast and therefore the definition of information displayed on the LCD module. The temperature compensation circuit is particularly suited for LCD modules used in level measurement systems installed in harsh industrial or outdoor environments.

Title: System and method for using session initiation protocol (sip) to communicate with networked appliances
Inventor: HUITEMA CHRISTIAN
IPC: G06F13/00
Filed: 2002-01-31
Abstract: Session Initiated Protocol (SIP) is used to communicate with Network-capable appliances by leveraging SIP capabilities to directly communicate with appliances, even when they are behind firewalls (116), Network Address Translators or other entities that prevent direct end-to-end communication. A  remote user agent client (UAC) (100) sends a message over the Internet via proxy servers (116) to a user agent server (204) at the location of the appliances, e.g., the client's home. This communications channel allows the client to control the appliances and to determine their status. In order to enable this operation, conventional SIP messages are extended to a DO message that includes a universal resource locator (URL) without location information otherwise specific in the SIP message and a generalized payload body with control and/or query instruction specific to networked appliances. When the command message is a SIP INVITE type, it includes a description of the appliance.

Patent CA-2461441-A1 (CA)
Inventor: GYSLING DANIEL
IPC: G01N9/00
Filed: 2002-11-05
Abstract: The density of at least one fluid in a pipe is determined using a pair of effective sound speeds a1eff and a2eff of the fluid/pipe system. The pair of effective sound speed measurements is taken at two sensing regions along the pipe wherein each of the sensing regions has a different cross sectional area compliance. The pair of effective sound speeds a1eff and a2eff is provided to signal processing logic (60), which determines the density of the fluid flowing in the pipe. The effective sound speeds a1eff and a2eff may be provided by a pair of sound speed meters positioned at the sensing regions wherein the sound speed meters utilize a spatial array of acoustic pressure sensors placed at predetermined axial locations along the pipe. The acoustic pressure sensors measure one-dimensional planar acoustic waves that are lower in frequency (and longer wavelength) signals than those used for ultrasonic flow meters, and thus is more tolerant to inhomogeneities in the flow. In addition, no external acoustic source is required and the meters may operate using passive listening.
