Abstract: A system and method is provided for incorporating host-device communication in wireless IJSB (WUSB). A host (101) either uses a multicast Distributed Reservation Protocol (DRP) frame on behalf of connected devices (102) to reserve wireless channel resources, a unicast DRP frame or Enhanced Distributed Channel Access (EDCA) with a Poll Frame. In the case of a unicast DRP frame the number of unicast frames sent for reservation depends on the number of connected devices (102).

Abstract: A method for detecting the presence of a television signal embedded in a received signal including the television signal and noise is disclosed. Either first-order or second order cyclostationary property of the signals may be used for their detection. When the first-order cyclostationary property is used, the following method is used, the method comprising the steps of upsampling the received signal by a factor of N, performing a synchronous averaging of a set of M segments of the upsampled received signal, performing an autocorrelation of the signal; and detecting the presence of peaks in the output of the autocorrelation function. When the second order cyclostationary property of the signal is used, the method comprising the steps of delaying the received signal by a fixed delay (symbol time), multiplying the received signal with the delayed version, looking for a tone (single frequency) in the output.

Abstract: An apparatus and method is disclosed for announcing to a wireless station in a wireless network that a Quality of Service (QoS) service schedule is pending for the wireless station. The apparatus of the invention comprises a hybrid coordinator that is capable of creating and sending to the wireless station an announcement of a pending Quality of Service (QoS) service schedule. The wireless station delays entering a power save mode of operation until the wireless station receives the QoS service schedule or until a selected timeout period expires.

Abstract: A method and image processing system are disclosed that extract feature information from an image using a model. An object in the image is first identified. The model is used at the front-end to quickly determine/define the approximate location/position of specific features of the object. Based in this modeling information, the location/position of the specific features are then determined. A feedback process may also be used to update/customize the model and improve performance.

Abstract: The system disclosed herein builds a database of image-related data by inputting a plurality of images, and for each image: dividing the image into N1 (N1≧1) regions which are substantially homogenous with respect to at least one attribute of the image, generating a graph based on M1 (M1≧1) of the N1 regions, and storing data for the graph in the database. The database may then be used to determine whether a query image is similar to one or more of the plurality of images. To this end, the system inputs the query image, and divides the query image into N2 (N2≧1) regions which are substantially homogenous with respect to at least one attribute of the query image. The system then generates a graph based on M2 (M2≧1) of the N2 regions, and compares the generated graph to other graphs in the database that correspond to the plurality of images. Thereafter, an image is retrieved from memory that has a graph that is substantially similar to the generated graph.
