Patent number: 11611322Abstract: An amplifier having one or more channels where each channel includes a two half bridges (a master and slave sub-channel). The sub-channels can be connected either in parallel or in a full-bridge configuration via internal switches that route signals to a pair of speaker jacks. One switch in the amplifier has a first position that selectively connects the outputs of the master and slave sub-channel to the same input of the speaker load so that the two sub-channels will drive the speaker load in parallel and a second position where the output of the slave sub-channel is connected to another input of the speaker load so that the master sub-channel and the slave sub-channel will drive the speaker load in a Full-bridge configuration.Type: GrantFiled: July 12, 2021Date of Patent: March 21, 2023Assignee: QSC, LLCInventors: Anders Lind, Matthew Skogmo

Patent number: 11601557Abstract: Described are techniques for video bridging for conversion of IP network video streams to the USB Video Class (UVC). The conversion of IP video to UVC video can include the use of software-only conversions and hardware assisted conversions, and can be done within purpose-built “conversion” devices or as software only solutions operating within applications or drivers within the operating systems of the “end nodes”. The end-nodes simultaneously see and use multiple USB UVC video sources. The conversion process can also convert the USB UVC video control protocol to IP Video Stream control protocols.Type: GrantFiled: July 28, 2020Date of Patent: March 7, 2023Assignee: QSC, LLCInventor: Ryan Pring

Patent number: 11561813Abstract: Technology is disclosed for establishing and administering multiple virtual machines, each with an audio, video and control (AVC) operating system (OS). The technology can also establish and administer cloud based AVC OSs. A server implementing this technology can perform real-time AVC processing, alongside soft and non-real-time processing and can host multiple, independent, virtual AVC OSs. Each AVC OS can perform the processing for an AVC setup. Each of the AVC OSs can be operated by a corresponding virtual machine controlled by a hypervisor running on the server. A cloud based AVC OS can perform processing for a corresponding remote AVC setup comprising multiple AVC devices. An AVC routing system can cause AVC signals from a particular AVC setup to reach a corresponding cloud AVC OS and conversely can cause signals from an AVC OS to reach the correct destination device.Type: GrantFiled: December 21, 2018Date of Patent: January 24, 2023Assignee: QSC, LLCInventor: Gerrit Eimbertus Rosenboom

Patent number: 10749488Abstract: A multi-channel switchmode audio amplifier is configured by a programmed processor such that each channel drives separate loads, is connected in parallel or is configured in a bridge-tied mode as well as combinations thereof. In one embodiment, amplifier channels that are connected in parallel have power amplifiers that are driven with signals from a single modulator. A feedback circuit and error amplifier from one channel controls the modulated signal that is applied to each parallely connected amplifier channel. Current feedback circuits for parallely connected amplifier channels are eliminated by tightly controlling the timing of switching in the power amplifier output stages.Type: GrantFiled: December 5, 2016Date of Patent: August 18, 2020Assignee: QSC, LLCInventors: Patrick H.
