Power Supply Patents (Class 348/730)
  • Patent number: 10623814
    Abstract: Recovering a Remote PHY (R-PHY) device after a power interruption. A hardware component, upon detecting that input power to the R-PHY device will be imminently interrupted, provides an alarm signal to a central processing unit (CPU) in the R-PHY device. The CPU, in response to receiving the alarm, stores running parameter data for the R-PHY device in a non-volatile memory. The running parameter data is normally obtained through network communications during a boot operation of the R-PHY device. If certain conditions are satisfied, then the R-PHY device recovers from the interruption in input power using the stored running parameter data without obtaining the running parameter data through a normal boot operation, thus shortening the boot time.

  • Patent number: 10594508
    Abstract: Methods, systems and apparatuses are described for intelligent device integration. A device (e.g., an HDMI “smart” switch) with multiple communication interfaces (e.g., HDMI, LAN, BT, IR) may monitor communications for control signals from multiple controllers configured to control respective devices (e.g., HDMI source, sink and/or switch devices). A device LAN may couple HDMI source and sink devices and non-HDMI devices. LAN communications may be monitored for device and control information. Control signals from controllers may be used to control devices that the controllers and their control signals are not configured to control. Interpreted control decisions may be based on, for example, an interpreted control in the context of a detected configuration and/or state of devices. A device may, thereby, expand the utility of incompatible controllers (without reprogramming), integrate an environment of incompatible devices and controllers, and provide relief to end-users.

  • Patent number: 9001275
    Abstract: HDMI is a digital audio and video communications protocol commonly used in consumer electronics. HDMI is particularly synonymous with high fidelity audio and video. Even though HDMI is a digital communications protocol, the audio quality can be impaired by analog signal impairments and distortions even if there are no digital decoding errors. In particular, the very process by which the audio is converted from Digital (HDMI) to human audible “Analog Audio” can be prone to errors. This occurs when the Digital to Analog Converter (DAC) clock, which is derived from the HDMI TMDS clock or HDMI source, is “distorted” due to its jitter, resulting in erroneous sampling or outputting of vital audio samples, thereby reducing the audio quality of the experience. The present invention reduces the jitter on the TMDS clock, and hence the audio DAC clock, resulting in lower audio distortion.

  • Patent number: 8982282
    Abstract: A display apparatus and a method of searching for a channel in the display apparatus includes a plurality of tuners and a plurality of antenna ports respectively connected to the plurality of tuners. The method includes receiving a channel search command; if the channel search command is input, searching for one of the plurality of antenna ports that is connected to a satellite antenna to receive a broadcasting signal, if one of the plurality of antenna ports is connected to the satellite antenna to receive the broadcasting signal, setting one of the plurality of tuners connected to the one antenna port, to a main tuner, and performing a channel search through the tuner set to the main tuner. Therefore, although an antenna port connected to one of the plurality of tuners initially set to a sub tuner, the display apparatus performs a channel search through the corresponding tuner.
