Abstract: Systems and methods are presented for reconstructing sequences of video frames received from a sending device in a distributed video coding environment. Some of the video frames are received as key video frames fully encoded at the sending device. Others are received as non-key video frames partitioned into pixel blocks. Some of the pixel blocks are indicated for reconstruction via a corresponding previous pixel block of a previous video frame, while other pixel blocks are to be reconstructed by decoding encodings of those pixel blocks received from the sending device. Each received encoding of a pixel block is based on contents of the non-key video frame that contains the pixel block and not on contents of the previous key video frame, nor on contents of any other video frame positioned between the previous key video frame and the non-key video frame in the sequence of video frames.

Abstract: Systems and methods are presented for processing sequences of video frames in a distributed video coding environment. Video frames chosen as key video frames are encoded in their entirety on a sending device, and the encodings are forwarded to a receiving device. Non-key video frames are partitioned into blocks of pixels which are individually processed at the sending device. Some pixel blocks are designated for reconstruction at the receiving device using a similar corresponding pixel block from a previous video frame, and the sending device does not encode those pixel blocks. Other pixel blocks are compressed at the sending device into representations that are sent to the receiving device to facilitate reconstruction of the other pixel blocks at the receiving device. Exceptional efficiency and accuracy may be achieved by employing spatiograms and singular value decompositions in processing pixel blocks of the non-key video frames at the sending device.

Abstract: Techniques to generate invoices for “events” (e.g., activities, orders, and so on) and taking into account applicable entitlements. The events are for actions and/or transactions to be performed, and may be related to contracts having entitlements that may specify special pricing for the events. An entitlement may define what event items are covered (e.g., time, expenses, parts), and the amount that is covered and the applicable discounts for each event item. To generate invoices for the events, contracts applicable to the events are initially determined and any entitlements that cover the events are identified. An original invoice amount for each event may be initially determined based on a standard pricing scheme (e.g., based on standard Price and/or Rate Lists) for this type of event. A revised invoice amount and discounts (if any) may then be determined for the event based on the applicable entitlements (if any).

Abstract: Two single phase uninterruptible power supplies are coupled together and controlled such that the two-phase output voltage is matched in frequency and phase with the electrical power provided by the electric utility. The phase difference between the electric utility power lines is measured and stored as a reference signal. When electrical power from the electric utility is lost, the stored reference signal is used to control a master and slave UPS to deliver two-phase power having the same frequency and phase.
