Title: Pressure relief valve monitoring device
Inventor: FRIEND RONALD G
IPC: F16K37/00
Filed: 1999-04-22
Abstract: A pressure relief valve monitoring device (8) is provided. The monitoring device includes a sensor input module (10) located proximate to a pressure relief valve (13), a microcontroller located within the sensor (12) input module, and a real time clock/calendar also located within the sensor (15) input module. The monitoring device also includes a number of sensors, including (1) a position sensor (14) mounted on the pressure relief valve for measuring the position of the valve's closure element relative to the inlet nozzle seat and for generating a lift signal representative of such position;  (2) a pressure sensor mounted on the pressure relief valve for measuring the pressure of the pressure system and generating a pressure signal representative of such pressure; and (3) a leakage sensor mounted on the pressure relief valve and positioned in close proximity to the inlet nozzle seat and capable of detecting noise generated by leakage of fluid between the inlet nozzle seat and the closure element when the closure element is engaged with the inlet nozzle seat. The microcontroller is configured to receive and store signals from any or all of the three sensors and correlate the receipt thereof with an indication of time from the real time clock/calendar to determine certain characteristics of valve performance. A method for monitoring the operation of the pressure relief valve is also provided.

Patent CA-2333253-A1 (CA)
Title: Molecular torches
Inventor: BECKER MICHAEL M
IPC: C12Q1/6818
Filed: 1999-07-01
Abstract: The present invention features "molecular torches" and the use of molecular torches for detecting the presence of a target nucleic acid sequence. Molecular torches contain a target binding domain, a target closing domain, and a joining region. The target binding domain is biased towards the target  sequence such that the target binding domain forms a more stable hybrid with  the target sequence than with the target closing domain under the same hybridization conditions. The joining region facilitates the formation or maintenance of a closed torch.

Inventor: LANGLOIS ROBERT
IPC: G01R1/04
Filed: 2001-04-06
Abstract: This invention generally relates to the handling of integrated circuit or electronic modules which comprise interconnecting elements. The invention relates to a holder or template and method to hold such modules during processing and to test the elements and the interconnection of a grid array of elements attached to the electronic module. There is a requirement to be able to automatically align, hold and bring the columns of a column grid array module into contact with probe devices for testing of the columns and the module. To achieve this, a self-aligning module holder or template has been developed to ensure that the columns are properly aligned. The invention includes associated methods to automatically position and align the columns of the module in the holes of the template. A tester having a plurality of probes equal to the number of columns can be mounted below the template so that each of the probes is capable of contacting a respective column when the module is properly inserted into the template or holder.

Abstract: A method for forming the seat in a pulsed sampling valve used in a FTICR MS.  The valve has a ceramic ball (44) that closes against the seat to thereby se al the passageway (36) that is used for introduction of sample into the FTICR M S vacuum chamber. The material from which the seat is formed is chosen to withstand relatively high operating temperatures and a precise deburred hole  is drilled in that material. The pre-load spring (48) exerts a force against  the ball when the valve is assembled. The force initially exceeds the yield strength of the seat material to deform the material to form the seat.</SDOA B>

Title: Mobile navigation system
Inventor: PU QING KENT
IPC: H04W4/024
Filed: 2000-01-03
Abstract: A client navigation system establishes a wireless connection to a navigation server on a computer network. The client requests a route by uploading start and stop specifications. The server calculates an optimal route based on real-time data available on the network. The optimal route is downloaded to the client in a natural language description and is independent from the local mapping database software on the client and includes a plain text description for each link. The client reconstructs the optimal route which is displayed on the client navigation system. A user-interface that anticipates data being entered by users minimizes the data-entry process. The current GPS position is used to set the clock on the navigation system in the client. Maps are scrolled on a display so that a representation of the automobile is always pointing to the right or to the left for additional look-ahead space on certain display systems. A dialed number is used to query a local database for providing local time information and the telephone automatically displays the current local time.
