Patent CA-2465631-C (CA)
Inventor: SESSA EUGENE
IPC: B05B5/047
Filed: 2004-04-29
Granted: 2008-07-29
Abstract: A process and apparatus are provided for the application of a fluoropolymer coating to the threads of an internally threaded fastener. The fastener has a body and a threaded bore extending to opposing ends of the body to define opposing first and second openings in the fastener. The fastener is moved on a conveyor along a path of travel with its threaded bore in a predetermined orientation. As the fastener moves along its path of travel, the first opening is closed by means of an obstructing member, while an air stream carrying entrained fluoropolymer powder is directed from a nozzle through the second opening and into the threaded bore. The nozzle is stationary and is located at an axially displaced position relative to the second opening of the fastener and immediately adjacent the conveyor. Preferably, the nozzle includes a diffuser which directs the air stream and entrained fluoropolymer powder into the fastener bore in a diverging pattern. After the fluoropolymer powder is deposited onto the threads of the fastener, the conveyor moves the fastener through a heating station where the fluoropolymer powder is raised to its melting temperature causing it to melt and fuse into a generally continuous film covering the fastener's threads.

Title: A method and system for removing the effects of corneal birefringence from a polarimetric image of the retina
Inventor: ZHOU QIENYUAN
IPC: A61B3/12
Filed: 2003-09-30
Granted: 2012-02-07
Abstract: A scanning laser polarimetry (SLP) system that measures in vivo retinal nerve fiber layer (RNFL) retardance ( .delta.N, .theta.N) in a single measurement without a variable corneal compensator (VCC). The diagnostic signal is biased so that the detected RNFL retardance orientation angles are sufficiently similar at adjacent pixels in the retinal polarimetric image to permit resolution of the orientation angle ambiguity in a single polarimetric image without repeating the measurement at another signal polarization state. With a simple bias retarder, the effects of anterior segment retardance (.delta.N, .theta.N) can be removed from a single polarimetric image of the retina without a VCC. Alternatively, from two single polarimetric images obtained at two different bias retarder positions, the anterior segment retardance magnitude .delta.C and orientation .theta.C and the RNFL retardance magnitude .delta.N and orientation .theta.N can all be determined from the peripapillary RNFL image region alone.

Title: System for digital rights management using distributed provisioning and authentication
Inventor: PETERKA PETR
IPC: H04L29/06
Filed: 2003-12-29
Granted: 2013-06-25
Abstract: A digital rights management system (DRM) (100) for restricting and permitting content access in a digital content distribution network such as a network used to deliver television programming. The DRM uses distributed authentication and provisioning so that the potentially many different entities involved in the content distribution network can have localized management control. Distributed authentication can use single or multiple instances of authentication services. A ticket granting service (TGS) (108) is used to allow clients to request services. In one approach, multiple authentication services use a common key that is known to the TGS (108). In another approach, unique keys are provided to each authentication service and these keys are communicated to the TGS.

Abstract: A polycrystal silicon manufacturing apparatus capable of preventing molten silicon from being solidified at the lower end of a reaction tube due to the lowering of temperature at the lower end when the inner surface of the reaction tube is heated to a temperature equal to or higher than the melting point of silicon and deposited silicon is fallen to a lower collection part for collection. The apparatus comprises an infrared ray radiating device heating the outer periphery of the lower end part (2a) of the reaction tube (2) by infrared ray or a temperature lowering prevention means such as a lower end side coil (4L) formed of a coil near the lower end of a high-frequency heating coil (4) and having a heating strength increased more than that of a coil (4U) located above near the lower end part. When the reaction tube (2) is heated by the high-frequency heating coil (4), the temperature of the lower end part (2a) can be prevented from being lowered by the temperature lowering prevention means.

Abstract: An invention is disclosed that enables proxy Mobile IP registration to be performed in a secure manner. Various security mechanisms may be used independently, or in combination with one another, to authenticate the identity of a node during the registration process. First, an Access Point receiving a packet from a node verifies that the source MAC address identified in the packet is in the Access Point's client association table. In addition, as a second mechanism, the Access Point ensures that a one-to-one mapping exists for the source MAC address and source IP address identified in the packet in a mapping table maintained by the Access Point. As a third mechanism, a binding is not modified in the mobility binding table maintained by the Home Agent unless there is a one-to-one mapping in the mobility binding table between the source MAC address and the source IP address. Similarly, the Foreign Agent may also maintain a mapping between the source IP address and the source MAC address in its visitor table to ensure a one-to-one mapping between a source IP address and the associated MAC address. The MAC address is preferably transmitted in a MAC address extension to the registration request and registration reply packets. In this manner, the Access Point, Home Agent, and Foreign Agent may ascertain the node's MAC address and ensure a one-to-one mapping between the IP address and the MAC address during the registration process.

Title: Methods and apparatus for providing a tolerable delay for slotted messages in wireless communication networks
Inventor: WILLEY WILLIAM DANIEL
IPC: H04L69/14
Filed: 2004-12-07
Granted: 2011-06-14
Abstract: In one illustrative example, a plurality of page message requests for a plurality of mobile devices which operate in a wireless communication network are received. One or more paging slots assigned to the mobile devices are identified for transmitting a plurality of page messages in response to these requests. However, the wireless network refrains from causing a page message for the mobile device associated with a tolerable delay indication to be transmitted within the one or more paging slots when a paging capacity limit of the one or more paging slots is reached. This allows higher priority page messages to be transmitted within the one or more paging slots. The wireless network subsequently causes a page message for the mobile device having the tolerable delay indication to be transmitted within one or more subsequent paging slots within a tolerable delay period corresponding to the tolerable delay indication. The mobile device may transmit the tolerable delay indication to the wireless network in response to identifying a predetermined condition, for example, identifying use of a high capacity power source.

Abstract: Methods and systems for determining the resonance frequency of a resonator by Doppler effect. An interrogating sonic beam including a carrier and one or more resonator exciting frequencies is used to excite a resonator (20). The carrier frequency is modulated by the resonator~s vibrations. The received signal is analyzed (38) to determine the amplitude of the Doppler shifted sideband frequencies, and the data processed to determine resonance frequency and/or to center the sonic beam on the sensor. Calibration of the sensor~s resonance as a function of a physical parameter in the measurement environment allows the determination of the parameter value. The methods and system may be used to determine cardiovascular or intra-cranial pressure or pressure in other body cavities or in an industrial environment.
