  • Patent number: 10432753
    Abstract: A method may include receiving peer data describing a set of peer clients associated with a demand response application server and describing how the peer clients communicate with one another. The peer data may be configured so that a subset of the peer clients directly communicate with the demand response application server and the demand response application server does not directly communicate with each of the peer clients. The method may also include receiving announcement data describing an event specified by the demand response application server and determining event response data responsive to the announcement data. The method may also include identifying, from the set of peer clients specified by the demand response application server, a set of recipient peer clients to receive the event response data.

  • Patent number: 10341944
    Abstract: A system, a program and a method allow a wireless terminal to discover an objective access point with a comparatively small amount of consumption energy and in a comparatively short waiting time. The access point (AP) includes: an AP WLAN communicator communicating using a predetermined available channel of a first frequency band; a pointer signal generator generating a pointer signal including available-channel information in the first frequency band and a network identifier; and an AP pointer signal communicator using a specific channel of a second frequency band to send the pointer signal to the wireless terminal. While, the wireless terminal receives the pointer signal through the specific channel and controls, in response to the available channel information and network identifier included in the pointer signal, for waiting for receiving a beacon or a probe response transmitted in the first frequency band from the objective access point.

  • Patent number: 10313808
    Abstract: An electronic device having a device housing includes a loudspeaker and several microphones within the device housing. A control circuit is electrically coupled to the loudspeaker and microphones. The loudspeaker produces speech and/or music. The control circuit determines a statistical measure for a first data set representing individual impulse responses from the plurality of microphones and compares that to a predetermined statistical measure for a second data set representing individual object-free impulse responses from the plurality of microphones to determine if an object is near the device. The statistical measure may be variance and may be computed in the time domain. Variance may be calculated using differences between the individual impulse responses and a mean impulse response that is a linear combination of the impulse responses for the plurality of microphones. The control circuit may include echo cancellers to mitigate common signals and/or other acoustic sources.

  • Patent number: 10306570
    Abstract: Disclosed is a method for transmitting a signal by a terminal via a device to device (D2D) link in a wireless communication system. Specifically, the method comprises: a step for receiving information on a timing advance (TA) value from a base station; a step for transmitting the TA value to a counterpart terminal via a first D2D control channel; and a step for transmitting a D2D data channel based on the first D2D control channel to the counterpart terminal by applying the TA, wherein the TA is not applied to the first D2D control channel. In particular, when the information on the updated TA value is received from the base station, it is desirable to transmit the D2D data channel based on the first D2D control channel to the counterpart terminal by applying the updated TA, but in the case of applying the updated TA, not to apply the information on the TA value included in the first D2D control channel.
