Title: Amino acid modified polypeptides
Inventor: ZHANG GUANGHUI
IPC: C12N1/21
Filed: 1999-10-06
Abstract: Incorporation of certain amino acid analogs into polypeptides produced by cells which do not ordinarily provide polypeptides containing such amino acid analogs is accomplished by subjecting the cells to growth media containing such amino acid analogs. The degree of incorporation can be regulated by adjusting the concentration of amino acid analogs in the media and/or by adjusting osmolality of the media. Such incorporation allows the chemical and physical characteristics of polypeptides to be altered and studied. In addition, nucleic acid and corresponding proteins including a domain from a physiologically active peptiDe and a domain from an extracellular matrix protein which is capable of providing a self-aggregate are provided. Human extracellular matrix proteins capable of providing a self-aggregate collagen are provided which are produced by prokaryotic cells. Preferred codon usage is employed to produce extracellular matrix proteins in prokaryotics.

IPC: A61M5/50
Filed: 1999-11-03
Abstract: A single-use safety syringe assembly comprises an elongated, generally cylindrical barrel which forms a hollow nozzle located at the distal end of the barrel and which opens into the interior of the barrel. A plunger is slidably mounted in the barrel and forms a longitudinal cavity. A needle holder carries a hollow needle on its distal end, and the needle holder is slidably mounted in the longitudinal cavity of the plunger. A biasing arrangement urges the needle holder in a direction for retracting the needle into the barrel. However, a releasable latching arrangement retains the needle holder against the urging of the biasing arrangement in a position wherein the needle projects from the barrel. An In-Barrel assembly sequence is provided which permits sequentially inserting components of the syringe into the barrel and effecting assembly with a push of the plunger. An OTN catheter may also be employed in combination with the syringe assembly.

Title: Roll sensor system for a vehicle
Inventor: WEAVER RALPH M
IPC: B60R21/00
Filed: 1999-11-26
Abstract: A roll sensor system for a land vehicle is provided to determine when a vehicle roll condition has occurred and to trigger a safety system in response to that determination. In certain embodiments, an angular rate sensor is used to obtain an angular rate and, from the angular rate, an angle relative to the roll axis of the land vehicle. If the angular rate and the angle correspond to a safety system activation event, the roll sensor system will provide a trigger signal to the safety system. In some embodiments, the system includes an incline sensor to aid in detecting and compensating for drift in the output of the angular rate sensor. In other embodiments the output of an angular rate sensor is used to validate the output of the incline sensor to aid in determining whether a vehicle safety system trigger event has occurred.
Patent CA-2291430-A1 (CA)
Inventor: LU TAO
IPC: H04L9/32
Filed: 1999-12-01
Abstract: A method and apparatus for verifying that the bearer of a user card is authorized to use the card. A dynamic personal identification number (PIN) is used to provide improved security. The PIN comprises an event identifier and a pseudo-random number sequence identifier. On each transaction, the user card generates a new PIN by generating a distinct pseudo-random number based on a private seed and the previous random number stored by the user card and incrementing the value of the event identifier. The PIN is then transmitted to an authentication server along with a pre-established user account name. The authentication server then retrieves the private seed, and previous event and pseudo-random identifiers from a secure account database associated with the account name. The authentication server ensures that the stored event identifier corresponds to the event identifier provided by the user by incrementing the event identifier if necessary and by generating a successive pseudo-random identifier each time the event identifier is incremented. Once the event identifiers correspond, the latest pseudo-random identifier is compared with the pseudo-random identifer transmitted by the user within the PIN. If authentication is successful, the authentication server will then complete the financial transaction associated with the user's request.

Title: Revenue meter with power quality features
Inventor: ANTONIOU CONSTANTINE A
IPC: G01R21/133
Filed: 2000-02-21
Abstract: Power quality detection, monitoring, reporting, recording and communication in a revenue accuracy electrical power meter is disclosed. Transient events are detected by monitoring the wave shape of the electrical power and comparing deviations to a known threshold. Sags and Swells are detected by computing root mean square value over a rolling window and comparing the computed value with a known threshold. Harmonic frequencies and symmetrical components are quantified by a known algorithm and compared with a known threshold. Incoming waveforms are stored to memory. All recorded and computed data is moved to non-volatile storage via direct memory access transfer in the event that a power quality event jeopardizes the operating power of the meter. Further, the meter provides a power supply utilizing high and low capacitive storage banks to supply sufficient energy to survive short duration power quality events which jeopardize the meter's operating power.

Patent CA-2309427-A1 (CA)
Inventor: SVIESTINS EGILS
IPC: G01S15/86
Filed: 1998-10-26
Abstract: The present invention is in general related to automatic alignment in multi-sensor target tracking. The process of the invention repeatedly generates estimates for sensor bias errors (b) by minimising a function, given on one hand by the magnitude of the discrepancy between measurements (M) and a measuring model, where the measuring model is a function of the unknown target location and unknown bias parameters, and on the other by the bias parameters and their predetermined statistical distributions (15). In a preferred embodiment of the present invention, the minimising step is performed by linearising components of the function around an approximate target position (normally obtained from the tracker (10)) and around nominal (typically zero) bias errors, and the function is subsequently minimised with respect to target positions as well as to the bias parameters (b). In addition, possible time dependence of the bias parameters are modelled by the incorporation of process noise.
