Abstract: A sound processing system adaptively mixes active matrix decoding and passive matrix processing of incoming audio signals. Mixed output signals are generated with active matrix decoding where the audio signals are stereo. Mixed output signals are generated with passive matrix processing where the audio signals are monaural. The sound processing system reduces the degree of active matrix decoding in the mixed output signals where the incoming audio signals are stereo and monaural. The sound processing system also generates virtual stereo signals from incoming audio signals having monaural signals. Mixed output signals are generated of the virtual stereo signals using active matrix decoding.

Patent CA-2748483-C (CA)
Inventor: WIMMER WOLFGANG
IPC: H04B15/00
Filed: 2010-01-12
Granted: 2016-05-03
Abstract: The present invention increases reliability of communication over a non-deterministic communication channel, and is particularly suited for inter-substation teleprotection in electric power systems. A communication channel is being monitored based on regular network traffic, i.e. by evaluating messages or data packets carrying real-time operational data as a payload. A  permanent determination of a channel quality, including appropriate alarming in case the channel quality is found insufficient, is based on an evaluation, at a receiving node, of data packets continually transmitted by a sending node. These continually or repeatedly transmitted data packets may comprise identical payloads reflecting current states rather than state changes as operational data.

Abstract: The subject of the invention is a rectifier system for a primary AC  electrical power distribution system comprising a PFC circuit connected onto the primary distribution system which delivers a DC power supply and means for storing electrical energy connected to the outputs of the PFC via a switching circuit. This circuit is controlled in such a manner as to effect either the discharge of the electrical energy stored in the storage means onto the DC power supply line, or the charging of the storage means by the DC power supply line. A first control circuit determines the state of operation of the switching circuit by comparing the value of the voltage on the power supply line with a first reference voltage. A second control circuit regulates the power delivered by the PFC over the power supply line by comparing the voltage present at the output of the storage means with a second reference voltage. The two control circuits are crossed. The system according to the invention advantageously allows load demands to be handled without causing interference to the primary distribution system.

Abstract: A packer for sealing against an inner cylindrical mandrel 10 and a wellbore wall 200, including a packer element having two groups of annular segments 120 positioned around the mandrel 10. Each segment 120 includes an inner end provided with an inner seal 122 against the mandrel 10, and an outer end able to expand radially and slide over the inner end of a neighbouring segment when the two annular segments are pressed axially towards each other. An actuating piston 160 may press the segments 120 together so that the segments slide into each other to seal against the wellbore wall 200 in a series of sealing surfaces 130. Advantageously, the segments 120 can be made of an elastic material, and in such a manner that the segments closest to the centre of the packer element are softer than the segments near the ends of the packer element. A spring package 150 may function to press the segments together as the elastic segments age and lose their elasticity. Alternatively, the segments 120 could be made of a deformable material. The packer is especially suited for open boreholes or in rough surfaced downhole pipes.
