Patent CA-2275344-A1 (CA)
Inventor: BALL STUART R
IPC: G01F23/26
Filed: 1997-12-15
Abstract: A sensor detects when a probe contacts liquid in a container due to a change in frequency of a probe oscillator. The sensor can have its output compared to a reference level to determine the presence or absence of liquid wherein in the reference level is changed to follow the output of the detector. In one embodiment, it can be determined that liquid has been contacted when a count has been reached several times in a row (the count being a function of the probe output and changeable). In another embodiment of the invention, it can be determined that liquid has been contacted when a count has been reached within a certain threshold several times in a row, while still having the reference count change to follow the probe output (regardless of the threshold). A digital counter can be provided to determine the frequency of the probe oscillator. A reference counter can also be provided to tune the count (frequency) from the probe oscillator counter to thereby compensate for drift. And, the adjustable detection threshold permits control of the sensitivity by changing the parameters of the circuit.

Patent CA-2299571-A1 (CA)
Inventor: LU PAO-SHU
IPC: A47K5/12
Filed: 2000-02-24
Abstract: Claimed and disclosed is a sound emitting liquid dispenser including at least one pump dispenser having contact surfaces and a first end and a base wherein an actuator is disposed within the pump dispenser in order to dispense a liquid, the base of the pump dispenser having at least one protrusion or a male adapter, a hollow pedestal to receive the pump dispenser wherein the circumference of the pedestal is relatively larger than the base of the pump dispenser, the pedestal having a top surface and a bottom surface wherein the top surface having at least one recesses and comes into contact with the pump dispenser contact surfaces and matingly-fitted with the male adapter, a flexible member disposed within said pedestal and is in surrounding relationship with a pressure activated sound emitting device so as to enable the pressure activated sound emitting device to come into contact with the contact surfaces of the pump dispenser, such that when pump dispenser is activated, the flexible member is compressed, whereby the pressure activated sound emitting dispenser is activated and sound is emitted. More particularly, the bottom surface of the pedestal has at least one perforation in order to drain excess fluid and to act as a volume regulator. Specifically, when the speaker of the pressure activated sound emitting device is in line with one of the perforations found on the pedestal, the sound generated is greater than when the speaker of the pressure activated sound emitting device is not in line with the perforations. Additionally, there is a protective casing surrounding the pressure activated sound emitting device to keep any undesirable element be it solid or liquid or air from coming into contact with the device. The pressure activated sound emitting device is further secured to the inner surface of the pedestal in order to ensure that the pressure activated sound emitting device is activated each time the pedestal comes into contact with the pump dispenser. It is further claimed that the sculptured appearance of the pump dispenser corresponds to the sound generated in the pedestal. Thus, for example, if the pump dispenser is in the shape of a cat, then the pressure activated sound emitting device will generate a meowing sound.

Title: Method and apparatus for data compression using fingerprinting
Inventor: MCILROY MALCOLM DOUGLAS
IPC: G06T9/00
Filed: 2000-02-29
Abstract: A method and apparatus for achieving relatively low compression ratios based on the realization of using a longer history and longer common strings of the input data stream as an initial evaluation of the input data prior to applying a particular compression process. More particularly, the input data is preprocessed by applying string-matching to the extract long common strings. The input data is divided into a series of blocks with each individual block having a uniform size, illustratively, 1000 characters in length. Further, a so-called fingerprint is computed and stored for each block. Thereafter, the input data stream is traversed and comparison is made between a particular set of character of the input stream and the computed fingerprints. In particular, the input stream is traversed as a function of a sliding window wherein the present window of characters of the input is compared to the computed fingerprints. Upon detecting a match, the input stream is encoded with an identifier determined as function of the detected match. Thereafter, a compression of the preprocessed and encoded input stream is made, illustratively, using Lempel-Ziv compression.

Patent CA-2311388-A1 (CA)
Title: Tool cooling system
Inventor: CHAMPNESS ELWOOD
IPC: F16L9/18
Filed: 1997-11-24
Abstract: A dual walled pipe string structure defines an annular cavity between the pipe walls into which hard granules may be packed to oppose wall collapse when inserted to high pressure well depths. Segments of pipe thus constructed will reduce heat transfer across the pipe string allowing for the conveyance of drilling mud from a surface cooler to a downhole tool with diminished elevation in temperature. The rate of cooled drilling mud transfer to the tool may be controlled to match the heat transfer rates and the heat generated at the tool. To further counteract downhole wall pressures, inert gas at a corresponding pressure may be introduced into the interstices between the granules.
