Patent CA-2721559-A1 (CA)
Title: Method for scalable access control decisions
Inventor: MOORE JONATHAN T
IPC: H04N21/4627
Filed: 2010-11-17
Abstract: Content access may be provided and processed by assigning responsibility for obtaining entitlement data to the client's browser. Thus, in one example, the client may be configured to synchronize and coordinate data lookups associated with a content request, rather than relying on the server to do so. The network architecture may use a mediator design pattern, in which the client's browser acts as the mediator (i.e., middleman) between a content server and an entitlement data server. Accordingly, synchronous calls between server-side services might not be required. Instead, data necessary for the content server to process a client request for access to protected content may be received in the incoming request from the client's browser.

Abstract: An artificial spinal disc implant (100) is provided that may be im-planted between adjacent vertebrae in the spine to replace, repair or augment a natural spinal disc. The spinal disc implant may be characterized by one or more biomechani-cal properties that approximate those of natural spinal disc. The implant is also de-signed to be sufficiently secured to the ver-tebrae so that it may function in the body for long time periods. The endplate of the implant comprises a series of arrangements of fixation elements (111 A-F). The volume of the fixation elements which are closer to the posterior side of the implant is greater than the volume of the other fixation ele-ments.

Abstract: A system and method for imaging biological samples on multiple surfaces of a support structure are disclosed. The support structure may, for instance, be a flow cell through which a reagent fluid is allowed to flow and interact with the biological samples. Excitation radiation from at least one radiation source may be used to excite the biological samples on multiple surfaces. In this manner, fluorescent emission radiation may be generated from the biological samples and subsequently captured and detected by detection optics and at least one detector. The captured and detected fluorescent emission radiation may then be used to generate image data. This imaging of multiple surfaces may be accomplished either sequentially or simultaneously. In addition, the techniques of the present invention may be used with any type of imaging system. For instance, both epifluorescent and total internal reflection (TIR) methods may benefit from the techniques of the present invention. In addition, the biological samples imaged may be present on the surfaces of the support structure in a random special pattern and need not be at known locations in order for the imaging to be performed.

Title: Methods and apparatus for identifying and categorizing distributed devices
Inventor: BUCCI GEORGE
IPC: H04W4/80
Filed: 2010-12-13
Abstract: Systems for identifying and categorizing distributed devices, e.g., lighting fixtures and thermostats, is disclosed. In an embodiment, a user (200) sends a low power discovery message to devices (201) using a portable programming tool (100). The devices (201) within range respond with identification information. The portable programming tool (100) organizes the responses by proximity and sends a "flash" message to the device with the closest perceived proximity. That device responds with a visual or audible signal (202), allowing the user (200) to determine whether that device is the one intended for selection. If so, the user initiates a store routine in which identification information, including category information, is stored in one or more locations, such as, the selected device (201), the portable programming tool (100), and/or a central or local controller (1100). The identification and categorization can, for example, be used to automate load shedding and to reduce energy consumption.

Abstract: The present invention relates to a method and system for controlling a wind power installation connected to an electrical power grid, in case of a fault in said grid.   In the electrical machines that form part of the wind power installation, generators and transformers, it is possible to change the impedance of the neutral closure introducing a plurality of active and passive elements.  This limits the currents during the grid fault, thereby reducing the peak torque in the mechanical train of the wind turbines and allows guaranteeing compliance with the network connection requirements, as control of the active and reactive currents is maintained at all times.
