Patent CA-2370219-A1 (CA)
Inventor: STOW JONATHAN JAMES
IPC: F01D11/14
Filed: 2002-01-31
Abstract: A method of machining an inner surface (56) of a shroud assembly (42) extending generally circumferentially around a central axis (18) of a gas turbine aircraft engine (10). The method includes determining pre-machined radial clearances (60) during flight between tips (26) of rotor blades (20) in the engine (10) and the inner surface (56) of the shroud assembly (42) at each of a plurality of circumferentially spaced locations around the shroud assembly (42). The inner surface (56) of the shroud assembly (42) is machined based on the pre-machined radial clearances (60) to provide a generally uniform post-machined radial clearance (60) during flight between the tips (26) of the rotor blades (20) and the inner surface (56) of the shroud assembly (42) at each of the circumferentially spaced locations around the shroud assembly (42).

Title: Wavelength compensation in a wsxc using off-voltage control
Inventor: LINDQUIST ROBERT G
IPC: G02F1/21
Filed: 2000-03-23
Abstract: A tunable liquid crystal switch (10) is disclosed. An electronic controller (30) provides an electronic drive scheme for achieving low intra-channel crosstalk of less than -40dB using only electronic compensation. A cross-tal k less than -50dB is provided by combining coarse temperature tuning and electronic compensation. This is achieved by designing the thickness (d) of the liquid crystal device (20) to cause a minimum to occur at a wavelength longer than a longest operating wavelength and at a temperature greater than  a maximum operating temperature. This ensures that the liquid crystal device (20) is tunable over all operating wavelengths and temperatures using electronic compensation.

Patent CA-2371413-A1 (CA)
Inventor: WOOD ROBERT L
IPC: B81B7/04
Filed: 2002-02-11
Abstract: Multiple microelectromechanical (MEM) device substrates, such as MEM mirror substrates, are tiled on a base substrate. Each MEM device substrate can include one or more MEM devices such as mirrors. By including one or a relatively small number of devices on a MEM device substrate, the MEM device substrate can be manufactured with relatively high yield and can be tested prior to tiling onto the base substrate. The separate MEM device substrates and base substrate can also reduce crosstalk and/or other signal interference which could degrade MEM device operation. Solder bumps and/or other mounting techniques may be used to mount the MEM device substrates onto the base substrate.

Title: Methods to isolate gene coding and flanking dna
Inventor: PICHE CAROLINE
IPC: C12Q1/68
Filed: 2002-03-08
Abstract: The invention provides methods for obtaining gene coding fragments, flanking fragments, or both gene coding and flanking fragments that can be readily characterized and used for a variety of purposes. The method involves preparing a genomic library comprising genomic DNA fragments, and hybridizing one or more nucleic acid primers, selected from a full-length cDNA, a 5' cDNA end, a 3'cDNA end, or a combination thereof, or a full-length mRNA, or portion thereof, or an RNA fragment, or a combination thereof, to the population of single stranded DNAs. A second strand is synthesized using a nucleic acid polymerase and the hybridized one or more nucleic acid primers, and a double stranded nucleic acid is produced. Any single stranded nucleic acid is removed and the nucleic acid reconstituted to produce a vector. This method is suitable for high throughput preparation and analysis of gene coding regions or flanking regions that can be used for preparing DNA arrays. Therefore, the present invention also provides arrays comprising flanking fragments, or flanking fragments attached to coding fragments. The present invention also pertains to promoter sequence tags, and 3' sequence tags.

Patent CA-2385681-A1 (CA)
Inventor: LANDESBERG AMIR
IPC: A61B5/00
Filed: 2002-05-09
Abstract: A system for assisting the failing ventricle, which utilizes a single blood displacement chamber and a single cannula. The cannula is inserted into the failing ventricle cavity and is connected to a blood displacement actuator. The device produces blood displacement at a critical time for a critical duration and with blood flow time course such that it improves the systolic function of the heart: augments the cardiac output and increases the generated pressure. The device also improves the diastolic function by increasing the ventricle compliance and imposing rapid relaxation of the ventricle wall. The device provides additional external work without deteriorating the mechanical function of the failing ventricular, moreover it decreases the energy consumption of the failing heart and improves the coronary perfusion.      Consequently, the device improves the balance between the energy supply (coronary perfusion) to the ventricle wall and the mechanical demands, and allows recovery of the failing heart.

Title: Communication infrastructure and method to speed uplink data setup
Inventor: BLACK JYOTI N
IPC: H04L12/56
Filed: 2002-05-27
Abstract: To address the need for a communication infrastructure and method to speed uplink data setup, the present invention provides for the assignment of uplink packet data resources by basestation transceiver systems (BTSs) (106) without the need to communicate with any packet control unit (PCUs) (110) first. The present invention accomplishes this by reserving packet data resources before they are needed or requested and providing them to BTSs (106) for assignment. Thus, BTS-PCU communication occurs in the period before an uplink connection is needed and after uplink data is established, effectively eliminating the BTS-PCU delay from uplink data setup. Moreover, the present invention provides for the transmission of transmit allowance messages before an uplink request is made by the communication unit (102), further reducing uplink data setup time.

Patent CA-2400668-A1 (CA)
Title: Firefighting garment
Inventor: TAYLOR FRANK P
IPC: A41D13/00
Filed: 2001-02-15
Abstract: A protective garment, such as a firefighting garment, that is relatively thin and light weight. The garment possesses relatively high resistance to liquid water absorption, yet also possesses relatively high moisture vapor transport characteristics when compared to conventional firefighting garments. The garment of the present invention includes an outer shell; a thermal liner posi-tioned within the outer shell; a moisture barrier positioned within the thermal liner and a face cloth positioned within the moisture barrier. The thermal liner is batting, knit, spunlace, woven textile or other suitable construction of a high heat and flame resistant material (such as an aramid or PBI material, or combinations thereof) that is treated with a durable, water repellant finish to minimize liquid moisture absorption by the thermal liner. Despite the liquid moisture absorption resistance imparted onto the thermal liner by the finish, the thermal liner still retains excellent moisture vapor transport characteristics. By positioning the treated thermal liner between the outer shell and the moisture barrier, the moisture barrier is protected from damage due to excessive thermal heat from the ambient and from abrasion and wear caused by the outer shell.  Additionally, by orienting the moisture barrier within the thermal barrier, the TPP (thermal protection property) of the garment is substantially increased. This allows for the reduction in the overall thickness and weight of the thermal liner throughout the garment.
