Abstract: Signal processing techniques are applied to digital image data to remove the distortion caused by motion of the camera, or the movement of the subject being photographed, or defective optics, or optical distortion from other sources. When the image is captured, the effect of relative motion between the camera and the subject is that it transforms the true image into a blurred image according to a 2-dimensional transfer function. The 2-dimensional transfer function representing the motion is derived using blind estimation techniques or by using information from sensors that detect the motion. The transfer function is inverted and used to define a corrective filter. The filter is applied to the image and the blur due to the motion is removed, restoring the correct image. Another embodiment uses the transfer function to avoid blur by combining multiple consecutive images taken at a fast shutter speed.

Abstract: The present invention modifies existing media independent handover (MIH) function (MIHF) frame format as defined by the IEEE 802.21 standard. In one embodiment, the variable load of the MIHF frame is modified to eliminate the MIHF variable header by defining the MIHF identification (ID) field and the session ID field as fixed fields in the MIHF fixed header. Thus, the MIHF variable load is only made up of the MIHF payload. In another embodiment, a field such as an information element (IE), a header, or MIH service data such as a command or an event, is represented by a type field, a length field and a value field (TLV). The length of the value field is exactly 128 octets, and the length field only occupies one octet.

Furthermore, a method to protect motors (M, M?) is provided, based on a set of rules (A, B, C) in order to characterize failures and trends of possible failures, so that the motor does not operate out of its specification for the system to deactivate it.

Abstract: A wireless transmit/receive unit (WTRU) may include two or more modems, each configured to link to a different network, and a media independent handover (MIH) client. An application programming interfaces (API) may provide the MIH client with mechanisms to receive information about links, control the modems for handover, discover a MIH server and IP multimedia system nodes, trigger mobile IP handover, etc. If a link has been successfully established, the MIH client may start a MIH session. When the modem indicates that a connection is going to be terminated, the MIH client may activate the second modem for handover. If the first modem indicates that a link parameter has crossed a threshold, the MIH client may send signal measurements to a MIH server. After receiving a media independent handover switch request, the MIH client may initiate handover to the second network.

Abstract: A precision high-frequency capacitor includes a dielectric layer formed on the front side surface of a semiconductor substrate and a first electrode on top of the dielectric layer. The semiconductor substrate is heavily doped and therefore has a low resistivity. A second electrode, insulated from the first electrode, is also formed over the front side surface. In one embodiment, the second electrode is connected by a metal-filled via to a layer of conductive material on the back side of the substrate. In alternative embodiments, the via is omitted and the second electrode is either in electrical contact with the substrate or is formed on top of the dielectric layer, yielding a pair of series-connected capacitors. ESD protection for the capacitor can be provided by a pair of oppositely-directed diodes formed in the substrate and connected in parallel with the capacitor.
