Disclosed herein are devices (e.g., audio playback devices) configured to transmit and/or receive wireless power. Wireless power can be transferred using mid-range or long-range techniques, such as electromagnetic radiation (e.g., lasers, microwaves) or electromagnetic coupling (e.g., inductive coupling, capacitive coupling). Device performance and/or power transmission may be modified dynamically based on wireless power levels, user behavior, the behavior of other devices, device grouping, or other parameters.

An Audio/Video (A/V) receiving device may include a display, a Radio Frequency (RF) receiving module configured to receive an RF packet from an A/V transmitting device, the RF receiving module including a plurality of antennas, and a microcomputer configured to obtain a distance between the A/V transmitting device and A/V receiving device and when the obtained distance is changed, display a first message indicating that a number of antennas to be turned among the plurality of antennas is changed according to the change of the distance.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for switching the output of an overriding multimedia device from a first input to a second input or a combination of the first input and the second input. An example embodiment operates by receiving sensor data detected by a sensing device and relating to a multimedia switching event. The example embodiment further operates by determining that sensor data detected by a sensing device corresponds to a multimedia switching action. In response, the example embodiment operates by generating a multimedia switching actuation signal that instructs an overriding multimedia device to switch its output from the first multimedia signal to the second multimedia signal. Subsequently, the example embodiment operates by transmitting the multimedia switching actuation signal to the overriding multimedia device.

Methods, systems, and apparatuses are described for automatically determining a state signature for consumer electronic device(s) coupled to a switching device and/or other devices communicatively coupled to the consumer electronic device(s). The state signature is indicative of functional state(s) in which the consumer electronic device(s) are in. Such states include a power state, a proximity state, a communication state, and/or an operational state of the consumer electronic device(s). Based on the state signature(s), the switching device may infer which of the consumer electronic device(s) the user would like to use (or is using) and cause action(s) to be performed. Such actions include automatically switching to the AV port(s) to which such consumer electronic device(s) are connected, transmitting command(s) to such consumer electronic device(s), transmitting a notification message to such consumer electronic device(s), etc.

It is made possible to consume current without adversely affecting the others. A cable is connected between a first device and a second device. A power line that supplies a current from the first device to the second device, and a current consumption unit that receives supply of a current from the first device through the power line, are included. A detection unit that detects that the second device is in the operating state, and a control unit that cancels a stop state of current consumption of the current consumption unit in response to the detection information, are further included.

Recovering a hardware component, such as a Remote MACPHY node (RMN), a wireless base station, a CATV amplifier, a Wi-Fi hotspot, a microcell, or a PON switch, 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.

A display device includes one or more sensors configured to obtain sensing data, a display, a communication interface configured to perform short-range wireless communication with a mobile terminal, and a processor configured to detect proximity of an object based on the obtained sensing data, perform automatic connection with the mobile terminal when the proximity of the object is detected, and display, on the display, information received from the connected mobile terminal.

Disclosed are an electronic apparatus, a display apparatus and a method of controlling the same an electronic apparatus, a display apparatus and a method of controlling the same, the electronic apparatus including: a speaker configured to output a sound; a microphone configured to receive a user voice; a communicator configured to perform communication; a processor configured to: identify a state of an external apparatus through the communicator based on reception of the user voice, process the received user voice and output a sound corresponding to a process result through the speaker based on identification that the external apparatus is in a turned-off state, and control the communicator to transmit information about the received user voice to the external apparatus and request the external apparatus to process the voice based on identification that the external apparatus is in a turned-on state.

A control device is provided. The control device includes a first communication interface unit which transmits a control command in a first communication mode which uses a bi-directional wireless communication, a second communication interface unit which transmits a control command in a second communication mode which uses a unidirectional wireless communication, a state determination unit which determines a communication mode of the control device, a user interface unit which displays a user interface window which corresponds to a determined communication mode and receives the control command with respect to a broadcast receiver and a control unit which transmits the received control command according to the determined communication mode.
