  • Patent number: 10687056
    Abstract: Reference prediction mode values, also referred to as most probable modes, usable for encoding or decoding of a prediction mode related to a current coding unit, are derived. First and second reference prediction mode values are derived (S402) from respective prediction modes of at least two neighbouring coding units of the current coding unit. The first and second reference prediction modes are different. A third reference prediction mode value is derived (S403) from the first and second reference prediction mode values. The third reference prediction mode is different from each of said first and second reference prediction mode values. By deriving three MPMs instead of two for comparison with the prediction mode of the current coding block the coding efficiency is improved. This is due to the increase in the probability that the prediction mode of the current coding block corresponds to one of the derived most probable modes.

  • Patent number: 10681236
    Abstract: An information processing apparatus capable of properly supplying electric power to a power supply destination associated with each function of a USB device. An MFP as the information processing apparatus is capable of operating in a power saving mode. A USB device having both of a Bluetooth communication function and a wireless LAN communication function is connected to the MFP. When an instruction for returning from the power saving mode is received from the USB device, it is determined whether the return instruction is an instruction generated due to the Bluetooth communication function or an instruction generated due to the wireless LAN communication function. Electric power supply destinations to which electric power is to be supplied when the information processing apparatus returns from the power saving mode are decided based on a result of the determination.

  • Patent number: 10681731
    Abstract: In an 802.11ax network with an access point, a trigger frame offers scheduled and random resource units to nodes for data uplink communication to the access point. To avoid the overall energy level seen by legacy nodes for a communication channel to drop below a detection threshold, the invention provides two tools. First, the scheduled and random resource units may be interleaved over communication channels. Second, unused resource units may be detected, and a node or the access point may send a padding signal on them to increase the overall energy level. The latter may be evaluated during a monitoring period before deciding to emit the signal. As the overall energy level seen by legacy nodes is increased, the risk that such legacy nodes do not detect activity on a 20 MHz channel having only a subpart of its RUs used is reduced. And risks of collisions are consequently reduced.

  • Patent number: 10678177
    Abstract: An energization controlling portion selectively controls energization of a plurality of heat generating elements so that electric power to be supplied to the heat generating elements to heat a non-image heating region, through which an image formed on a recording material does not pass, among a plurality of heating regions of an image heating portion, is smaller than electric power to be supplied to the heat generating elements to heat an image heating region, through which the image passes, among the plurality of heating regions. When an abnormality detecting portion detects an abnormality in an image forming apparatus, the energization controlling portion increases the electric power to be supplied to the heat generating elements to heat the non-image heating region.
