Patent CA-2640278-A1 (CA)
Inventor: ZUKOTYNSKI STEFAN
IPC: H01L31/0216
Filed: 2007-01-10
Abstract: The present invention provides a thin film amorphous silicon-crystalline silicon back heterojunction and back surface field device configuration for a heterojunction solar cell. The configuration is attained by the formation of heterojunctions on the back surface of crystalline silicon at low temperatures. Low temperature fabrication allows for the application of low resolution lithography and/or shadow masking processes to produce the structures. The shadowing losses are eliminated by positioning the electrical contacts at the back thereby removing them from the path of the incident light. Back contacts need optimization only for maximum charge carrier collection without bothering about shading losses. The open circuit voltage of the back heterojunction device is higher than that of an all-crystalline device. The solar cell configurations are equally amenable to crystalline silicon wafer absorber as well as thin silicon layers formed by using a variety of fabrication processes.

Patent CA-2641779-A1 (CA)
Inventor: OAKHAM PETER
IPC: G01N23/04
Filed: 2007-02-09
Abstract: The present invention provides a digital x-ray radiographic imaging system.  The system is based on a photoconductive detector and an electro-optic light modulator, where the photoconductive detector layer absorbs x-rays that have passed through an object to form an exposure of the object. The absorbed x-rays create a static optical image, which is stored in the electro-optic light modulator, allowing the capture of the optical image to continue over longer time. The optical image is digitized using a scanning system and an external light source. The image is then processed and stored by a computer. After the optical image is recorded, an erasing mechanism is used to reset the system before a new exposure is made.

Title: Association of networked terminals to a common account
Inventor: BOOTH ROBERT C
IPC: H04N7/16
Filed: 2007-06-26
Abstract: An arrangement is disclosed for providing an account identifier from a billing system to a controller that is disposed at the headend (705) of a wide area network ("WAN") (712) that supports a media content distribution service. In illustrative examples, the WAN (712) is a broadband network to which one or more terminal devices (732, 735X) such as STBs are coupled. The billing system (743) generates a unique household handle ("HHH"), to identify a particular set of STBs that are associated with a subscriber to the service, which is transmitted to the controller. The controller (719) uses the HHH to prepare a terminal association identifier ("TAI") that is distributed to the associated STBs. An application programming interface ("API") resident on each STB is arranged to accept input parameters from one or more applications that run on the STB. The input parameter is typically concatenated with the stored TAI and input to a hashing algorithm. The resultant hashed value is returned to an application and is usable as password to secure a local area network to which the STBs are coupled.

Title: Total fluid loss control system
Inventor: LANNOY JEAN-MICHEL
IPC: A61M1/34
Filed: 2007-12-21
Abstract: A system or method controls total fluid loss (TFL) in a patient undergoing hcmofiltration therapy administered through an extracorporeal circuit by frequently calculating and storing a retrievable value representing TFL. At session start or restart, the value is read to determine whether TFL is out of tolerance, and if so, fluid balance is restored before administering a prescribed therapy. The TFL value is calculated during therapy by measuring fluid added to the circuit and fluid removed from the circuit, and the result is stored as an updated value. Jf TFL drifts out of tolerance fluid flow rates may be temporarily changed until a desired fluid balance is restored. The system may include a microprocessor based advanced controller receiving the fluid measurements as feedback for regulating substitution fluid and filtrate flow rates, and updating the TFL value in non-volatile memory.
