Abstract: There is provided a method of detecting offset in a sense amplifier of an sRAM memory unit. The method comprises using a sense amplifier of the SRAM memory unit to implement a read of a first data value stored in a memory cell of the SRAM memory unit, and measuring a first time for the sense amplifier to read the first data value. The method further comprises using the sense amplifier to implement a read of a second data value stored in a memory cell of the SRAM memory unit, and measuring a second time for the sense amplifier to read the second data value. The method then comprises calculating a difference between the first time and the second time, and determining whether an offset adjustment should be applied to the sense amplifier in dependence upon the difference between the first time and the second time.

Abstract: A method and apparatus for identifying and analyzing an aircraft landing site during flight is provided. The method includes the steps of using image capture means such as an infrared camera to capture in-flight images of the ground in the region of a possible landing site, using a database of computer modelled images of possible aircraft landing sites mapped to a global co-ordinate reference frame to compare the in-flight images with a modelled image of the possible landing site and optimizing correspondence between the two images to obtain an in-flight image optimally mapped to the global co-ordinate reference frame. Thereafter, the landing site which corresponds to the optimally mapped in-flight image is analyzed to ascertain the presence of any obstructions such as life forms, vehicles or newly erected buildings thereon.

Abstract: Disclosed are apparatus and a method for detecting cloud features. The method comprises: obtaining (402) image data (401); identifying (404) regions of the image data corresponding to a below-horizon region and an above-horizon region; classifying (404) one or more parts of the above-horizon region as a cloud feature; determining (409) an identification model specifying a visual appearance of some or all of the parts of the above-horizon region that have been classified as a cloud feature; and using the determined identification model, classifying (404), as cloud features, those regions of the of the below-horizon region whose visual appearance is as specified by the identification model.

Abstract: A wireless communication system may include a plurality of nodes that use a medium access control (MAC) protocol to communicate over a shared medium or a primary channel. The MAC protocol may include a non-transmitting state during which one or more nodes are silent in the primary channel while two nodes in the wireless communication system are in communicating over the primary channel. Systems and methods described herein use medium access protocol (MAC) underlay signaling, which may include measuring or sensing availability for spectrum or transmitting data without the loss of network throughput over a secondary channel in a wireless communications system. In some embodiments, the systems and methods described herein use dynamic spectrum access (DSA) protocols to switch the channel of communication in the wireless communication system.

Abstract: Systems, methods and devices for providing stabilization between first and second vertebrae are provided. More particularly, in one form a system includes an implant configured to be positioned in a disc space between the first and second vertebrae and a freestanding plate for engagement with extradiscal surfaces of the first and second vertebrae. The system also includes an insertion instrument with an engaging portion configured to releasably engage with the implant and the plate such that the implant and plate can be positioned together relative to the first and second vertebrae. In one aspect, an angular orientation of the implant relative to the plate is adjustable when the implant and the plate are engaged by the instrument. In this or another aspect, the implant and plate are held in a contiguous relationship when engaged by the instrument.

Abstract: An exercise device providing a fore and aft horizontal component of striding motion that is dynamically user-defined, while providing a vertical component of the motion that is maintained on a predetermined vertically reciprocating path in some embodiments. The exercise device guides the user's foot in a pseudo-elliptical stride path, while providing a dynamically variable stride length that allows the user to move with a natural stride length. The exercise device allows tall and short users to extend or curtail the stride length to match their natural stride lengths. The length of the reciprocating path is dynamically adjusted during the exercise operation without equipment adjustments by changes in the length of the stride input by the user at a pair of foot engagement pads disposed on laterally spaced apart foot support members.

Abstract: A method of detecting at least one moving vehicle includes receiving (202) image data representing a sequence of image frames over time. The method further includes analyzing (204-206) the image data to identify potential moving vehicles, and comparing (208-212) at least one said potential moving vehicle with a vehicle movement model that defines a trajectory of a potential moving vehicle to determine whether the at least one potential moving vehicle conforms with the model.

Abstract: A computer-implemented method for identifying a potential reference is disclosed. In one embodiment, a user interface (UI) object (e.g., a one-click reference search button) is provided, for example, on a web page displayed at a user's client device. When selected, the UI object causes a reference search query to be generated. The search query identifies the user performing the search, and a target person for whom the user would like a reference. The search query is communicated to, and processed by, a social networking system (e.g., through an API function call). In turn, the social networking system returns information about potential references to the client.

Abstract: Matches between search queries and potential targets of such search queries are automatically brokered by (i) comparing search criteria specified in the search queries with profile criteria describing the potential targets, and (ii) reporting instances of acceptable correspondence between the search criteria and the profile criteria, provided that access controls associated with the profile criteria of the targets permit such reporting in light of access levels assigned to the search inquiries. Initiators, using client applications at various remote locations, may formulate the search queries and the brokering may be performed at one or more server locations communicatively coupled (e.g., via the Internet) thereto. The profile criteria may include portions of rich descriptive profiles of the potential targets.

Abstract: Electronic circuits in a register associated with a commodity usage meter capture energy from a meter reading device when the device is coupled to the register (e.g., either electrically or inductively coupled) for the purpose of reading metered quantity data from the register. Electrical charge obtained from the reading device may be stored in a high-capacity storage capacitor. When the capacitor is sufficiently charged, it provides power to at least part of the register circuits, such as a controller, for at least the duration of the communication session with the reading device. In some embodiments, the capacitor may additionally supply sufficient power to operate the register until a subsequent reading device coupling.
