Patent CA-2841052-A1 (CA)
Inventor: DENNIS KEVIN
IPC: H02J3/36
Filed: 2012-07-17
Abstract: The present invention provides a simplified method of controlling power among the various sources and loads in a power system. Power generating sources are each connected to a common DC bus through a converter. The converter selectively transfers energy to the DC bus at a maximum rate or at a reduced rate according to the level of the DC voltage present on the DC bus. At least one storage device is preferably connected to the common DC bus through a power regulator. The power regulator selectively transfers energy to or from the DC bus as a function of DC voltage level present on the DC bus. Further, an inverter may be provided to bidirectionally convert between the DC voltage and an AC voltage for connection to a customer load or the utility grid. Each power conversion device is independently controlled to provide a modular and simplified power control system.

Abstract: Systems, methods and devices are provided to alert a user of content delivered on multiple channels to events of interest occurring on channels other than the channel being listened to or viewed. Playback of content in which an event of interest or key event has occurred is time-shifted or delayed at the content transmission source or at the user device. Metadata that identifies events of interest in the content is transmitted to the user device. The user device generates alerts to the user based on the metadata in sufficient lead time to enable the user to not only tune to a channel on which an event of interest is occurring, but to do so sufficiently in advance of an event of interest so as to hear and/or see relevant portions of the content leading up to and/or following such an event

Title: Adaptive upsampling for spatially scalable video coding
Inventor: ROSSATO LUCA
IPC: H04N19/33
Filed: 2012-07-20
Abstract: A signal processor selects an element from a rendition of a signal at a first level of quality to upsample into multiple elements of a rendition of the signal at a second (higher) level of quality. The signal processor produces a metric based on settings of elements in a vicinity of the selected element in the rendition of the signal at the first level of quality. The metric defines a boundary between a first set of elements in a vicinity of the selected element and a second set of elements in a vicinity of the selected element. The signal processor utilizes the metric to calculate settings for the multiple elements in the signal at the second level of quality. A location and orientation of the boundary with respect to the selected element depends on the settings of elements in the vicinity of the selected element.

Abstract: A first switch for connection in a first circuit path between a PV panel string and an inverter in a power system, and a second switch for connection in a second circuit path across an output of the PV panel string, are normally closed and open, respectively, during non-fault operation of the power system. Both series and parallel arc faults in the power system can be extinguished by further control of the switches. Arc fault detection could be based on probabilistic frequency analysis of current or power flow measurements in the PV panel string, current or power imbalance, interruption in communications with the PV  panels, or combinations of these techniques.
