Patent CA-2231610-A1 (CA)
Title: Remote data acquisition system
Inventor: SMELQUIST KENNETH E
IPC: G08C19/00
Filed: 1998-03-05
Abstract: A remote data acquisition system,  comprising a flow  meter,   a  modem  connected  via  a  first  data communications link to the flow meter. A cell phone is connected through a data interface to the modem. The cell phone is controlled by a pager through a power control module, which also supplies power to the cell phone. Power to the modem is also controlled by the power control module. The remote data acquisition system of the invention is particularly suited for mounting in a manhole with the antenna being a flat antenna mounted outside of the manhole on a roadbed. The antenna is a flat antenna encased in a crush proof casing that is resistant to a motor vehicle's weight.
Patent CA-2231613-A1 (CA)
Title: Downhole system and method for determining formation properties
Inventor: KURKJIAN ANDREW L
IPC: E21B49/10
Filed: 1998-03-10
Abstract: In this invention, drill pipe or tubing is attached to a sampling tool that is suspended in a borehole. A wireline cable also connects the tool to surface equipment and establishes electrical communication between the tool and the surface equipment. A valve located in the docking head assembly controls fluid flow between the borehole and the drill pipe through a port located within the drill pipe assembly which is opened and closed as required. During operations, the tool takes fluid samples from the formation and analyzes them for contamination levels. Unacceptable fluid is pumped or flowed through the tool via a flowline and into the drill pipe where it is stored until it is disposed of at the surface. Once the flowing fluid reaches acceptable levels of contamination, this fluid is pumped or flowed into a sample chamber(s) in the tool. Once sampling is completed the contaminated fluid is forced to the surface by opening the port and pumping a different fluid down the borehole annulus, through the port and into the tool below the contaminated fluid and thereby filling the drill pipe and forcing the contaminated fluid up the drill pipe and to the surface, instead of discarding the fluid into the borehole or storing the fluid in the tool. This invention allows for larger amount s of fluid to be retrieved from the formation which results in cleaner fluid samples and better information about the formation. Moreover the nature of the pressure data acquired both during periods of flow and shut-in can be used to deduce formation permeability and permeability anisotropy.

Title: Adjustable hair curler and method of use
Inventor: HABIBI MASOOD
IPC: A45D2/18
Filed: 1996-10-10
Abstract: The present invention is directed to a novel adjustable diameter hair curler which is extremely lightweight, portable, and suitable for travel. The novel adjustable curler includes a sheet (10) of a flexible material such as a plastic or fabric or backing material. The sheet (10) has a first planar side (14) and a second planar side (18) opposite said first planar side. Attached to the first side (14) of the sheet (10) is an array of hook-type elements (12) from a hook and loop type fastening system such as VELCRO® brand hook and loop fasteners available from VELCRO Industries of Manchester, New Hampshire. The hook-type elements (12) are generally arrayed over the bulk of the first side (14). Attached to at least a portion of the second side (18) are loop-type fasteners (16) or a material which will stick to the hook-type fasteners (12). By rolling the sheet (10) to form a cylinder so that a portion of the sheet overlaps another portion of the sheet, the hook and loop fasteners (14, 16) may interact to hold the cylinder's shape with relative ease and complete adjustability of cylinder diameter. Lock-in of the shape may be accomplished easily with a single hand.  For storage, the sheets (10) may be completely flattened for storage or transport in a very minimal volume. ®

IPC: B65B29/04
Filed: 1996-11-15
Abstract: An infusion packet comprises a pair of sealed compartments (12a, 12b) containing infusion material and joined together at opposite ends of the packet. A drawstring (14) attached intermediate its length to a connecting region (8) between the two compartments at one said end has pull portions extending between the compartments from said attachment and held movably at the opposite end of the packet, whereby said pull portions can be drawn apart to contract the packet. To produce the packet the compartments are initially formed end to end, joined by the connecting region. An intermediate portion (16) of the drawstring is attached to the connecting region before the compartments are doubled over to bring their opposite ends together with drawstring pull portions between them. Said opposite ends are then secured together in a manner permitting movement of the drawstring pull portions between them to contract the packet.

Title: Frequency lock indicator for fpll demodulated signal having a pilot
Inventor: SGRIGNOLI GARY J
IPC: H03L7/087
Filed: 1997-07-24
Abstract: A biphase stable FPLL includes a polarity determination circuit (36) that ascertains the lockup phase of the FPLL based upon the polarity of the pilot in the digital signal. A frequency lock indicator circuit (50-60) determines from the recovered pilot when frequency lock has occurred and the polarity determination circuit is responsive thereto for inverting the phase of the incoming signal (or alternatively, of the outgoing signal) as determined in order to supply an output signal of predetermined polarity. The frequency lock indicator consist of a zero crossings detector (50) and a latch (56) that is sampled for a time period. The zero crossings detector (50) is a delay (52) and an exclusive OR gate (54). An optional confidence counter (60) may be used with the latch (56) to determine when frequency lock has occurred to provide the lock indicator signal.

Title: An apparatus and a method for a telecommunication system
Inventor: TEDER PAUL
IPC: H04B1/707
Filed: 1997-08-08
Abstract: A receiver device (703) downspreads signals from a band spreading signal, which generates downspread symbol sequences (803). A vector generator (704) generates symbol vectors (805) which include a symbol from each downspread symbol sequence (803). An auxiliary receiver (705) detects symbol vectors (805) in a first window (809) with the length of one symbol time. The auxiliary receiver (705) generates provisional estimates of the symbol vectors (805) with the help of a device with a first window algorithm (811). A delaying module (706) delays the symbol vectors (805) from the vector generator (704) by one symbol time before they reach a main receiver (707). The main receiver (707) detects in a second window (806) the symbol vectors (805) with the length of one symbol time. The main receiver (707) uses a device with a second window algorithm (808) in order to estimate the received symbol vectors (805) with reference taken to the previously estimated symbol vectors in the main receiver (705) and the provisional estimates of the symbol vectors (805) from the auxiliary receiver (705). A component generator (710) divides up the estimated symbol vectors (807) from the main receiver into separate components (815).

Title: Electronic display sign
Inventor: HUIZEN RONALD LAURENCE
IPC: G09G3/32
Filed: 1999-06-02
Abstract: A modular electronic display sign for displaying colour images is described. The display sign is constructed of pixel groups respectively associated with n pixel controllers, each pixel controller controlling light sources of one of n primary colours.      Image data is transmitted from a sign controller via system buses to the respective pixel controllers. Timing signals are generated at predefined refresh rate by each pixel controller. Pulse-width modulation is used to control the individual brightness of the light sources of each primary colour. A lookup table is used by each pixel controller to increase the granularity of control of the pulse width modulation. The display sign enables the display of monochromatic dichromatic or full colour images at rates exceeding 30 frames a second. The advantages include low manufacturing and maintenance cost for a high performance multi-colour display sign.
