Patent CA-2362517-A1 (CA)
Title: Method and apparatus for gps assistance in a communication system
Inventor: AGASHE PARAG A
IPC: G01S19/27
Filed: 2000-02-14
Abstract: A method and apparatus for efficiently transmitting location assistance information to a mobile communication device over a control channel with a minimal impact on the capacity of the control channel. A  position location server provides a difference between satellite locations which have been computed using Almanac data and then Ephemeris data. Sending only the difference between the locations and clock corrections computed using the two different data types, the total amount of information to be transmitted to a mobile communication device is significantly reduced.  Furthermore, by providing rate of change information, the method and apparatus allows the location assistance information to remain valid for a relatively long time after it has been received by the mobile communication device.

Patent CA-2364147-A1 (CA)
Inventor: ANDREYCHUK MARK T
IPC: E21B7/02
Filed: 2001-11-28
Abstract: An improved mast arrangement for a mobile multi-function rig has a winch line extending from an upper end of the mast and a traveling block supported thereon. A trolley mountable on the mast is adapted for coupling to the traveling block.  The trolley works primarily as a guide for a given load, and therefore is of a lightweight design since loads mounted to the trolley are transferred directly to the traveling block and the supporting winch line. The trolley provides the capability to readily switch between various rig operations, including manipulating coiled tubing with an injector, setting surface casing using a top drive, operating the winch and traveling block for joined pipe operations, and interchanging between top drive and joined pipe operations without removing the top drive from the mast or rig. The rig can run deeper joined pipe applications than previous mobile rigs by providing means for employing the top drive, namely the trolley is adapted to counteract the torsion exerted by the top drive during operation. The trolley is able to work the entire length of the mast after quickly parking the injector near the bottom of the mast. The winch and traveling block have unobstructed travel along the entire length of the mast without disengaging the trolley from the mast and with the injector parked near the bottom end.

Title: Lifting apparatus for implementing a rectilinear movement of a handling device
Inventor: STOBER MANFRED
IPC: B66D3/18
Filed: 2001-12-04
Abstract: A lifting apparatus includes two parallel longitudinal members interconnected by at least one connecting element. A lifting beam is movable by a drive mechanism along the longitudinal members and supports, directly or indirectly, a handling device. Extending parallel to and supporting the lifting beam is a guide rail, which is received in spaced-apart carriages, for displacement lengthwise of the longitudinal members in a freely running manner, as the lifting beam is moved by the drive mechanism. The carriages are arranged in a space between the longitudinal members and secured to the connecting element, wherein the longitudinal members and the lifting beam are formed with longitudinal grooves for engagement of sliding blocks so that the connecting element, the drive mechanism and the carrying unit are securable to the longitudinal members in any desired longitudinal position, and the guide rail is securable to the lifting beam in any desired longitudinal position.

Patent CA-2368453-A1 (CA)
Title: Using gain-adaptive quantization and non-uniform symbol lengths for audio coding
Inventor: TRUMAN MICHAEL MEAD
IPC: G10L19/032
Filed: 2000-04-11
Abstract: Techniques like Huffman coding can be used to represent digital audio signal components more efficiently using non-uniform length symbols than can be represented by other coding techniques using uniform length symbols. Unfortunately, the coding efficiency that can be achieved by Huffman coding depends on the probability density function of the information to be coded and the Huffman coding process itself requires considerable processing and memory ressources. A coding process that uses gain-adaptive quantization according to the present invention can realize the advantage of using non-uniform length symbols while overcoming the shortcomings of Huffman coding.  In gain-adaptive quantization, the magnitudes of signal components to be encoded are compared to one or more thresholds and placed into classes according to the results of the comparison. The magnitudes of the components placed into one of the classes are modified according to a gain factor that is related to the threshold used to classify the components. Preferably, the gain factor may be expressed as a function of only the threshold value. Gain-adaptive quantization may be used to encode frequency subband signals in split-band audio coding systems. Additional features including cascaded gain-adaptive quantization, intra-frame coding, split-interval and non-overloading quantizers are disclosed.

Abstract: Ce procédé de transformation génétique de plantes, induit par Agrobacterium au moment de la floraison, peut s'appliquer à des plantes dicotylédones et monocotylédones pouvant être transformées par Agrobacterium, et il consiste à utiliser une infiltration sous vide pour introduire l'ADN-T de Agrobacterium portant un gène d'intérêt dans les plantes, de préférence des plantes que l'on a fait pousser à partir d'une graine vernalisée. Lorsque les graines recueillies à partir des plantes infiltrées arrivent à maturité, on les fait germer et on choisit dans la descendance de ces plantes celles qui portent le transgène. Ce procédé de transformation permet d'obtenir des plantes démontrant une hérédité stable du transgène, sans qu'il soit nécessaire de pratiquer des procédés de régénération, tels que l'embryogenèse ou l'organogenèse somatique.

Attenuated lipid A derivatives useful according to the subject invention include monophosphoryl lipid A and 3-O-deacylated monophosphoryl lipid A. A  surfactant or mixtures of surfactants are dissolved in a solvent. 1,2 Dipalmitoyl-sn-glycero-3-phosphocholine is a preferred surfactant. The dissolved surfactant is added to an attenuated lipid A derivative to obtain a mixture. The molar ratio of attenuated lipid A derivative to surfactant in the mixture is about 4:1. The solvent is evaporated and water is added to the resulting film. The suspension is sonicated in a 60 ~C water bath until it becomes clear. Animals administered the adjuvant formulation exhibited increased antibody responses to a given antigen as well as displayed enhanced lymphocyte proliferative and cytotoxic T-lymphocyte responses. Intranasal administration of the aqueous adjuvant composition and an antigen stimulates the production of serum and mucosal secreted IgA.

Title: Method and apparatus for determining the position of a mobile communication device using low accuracy clocks
Inventor: FORSTROM HOWARD
IPC: H04W64/00
Filed: 2000-08-02
Abstract: A position location communication system (10) determines the position of a master radio (12) using a round-trip messaging scheme in which the time of arrive (TOA) of ranging messages is accurately determined to yield the range estimates required to calculate the position of the master radio via trilateration. The master radio transmits outbound ranging messages to plural reference radios (14, 16, 18, 20) which respond by transmitting reply ranging messages. Upon reception of the reply ranging message, the master radio determines the range to the reference radio from the signal propagation time calculated by subtracting the far-end turn around time from the round-trip elapsed time. Any combination of fixed or mobile radios of known positions can be used as the reference radios for another mobile radio in the system, thereby providing adaptability under varying transmission conditions. The individual radios do not need to be synchronized to a common time reference, thereby eliminating the need for highly accurate system clocks.
