Disclosed is a battery management system (BMS) power supply management apparatus and method. The BMS power supply management apparatus includes an optoelectronic element configured to generate a current in response to an optical signal, a conversion element configured to convert the current into a wake-up voltage, and a first switch configured to switch a wake-up signal for a BMS, in response to the wake-up voltage.

A remote controller of an image processing apparatus includes: a touch screen which displays an input menu; a menu processor which processes the touch screen to display respective input menus corresponding to at least two modes among a control mode of the image processing apparatus, a character input mode and a handwriting mode; and a controller which controls the menu processor to display the input menu of the mode corresponding to a selection signal when the selection signal for the mode is received.

In order to provide a remote control system that is easy to use, a first displaying unit displays a remote controller side display information. Since a first operation unit is used to select the remote controller side display information and then drag towards an image display apparatus, a display position of the remote controller side display information on the display surface of the first displaying unit is visually moved towards an image display apparatus. In accordance with the movement operation of the remote controller side display information, operational information associated with the remote controller side display information is transmitted from a first communicator to a second communicator.

A hand-held electronic device having a remote control application user interface that functions to displays operational mode information to a user. The graphical user interface may be used, for example, to setup the remote control application to control appliances for one or more users in one or more rooms, to perform activities, and to access favorites. The remote control application is also adapted to be upgradeable. Furthermore, the remote control application provides for the sharing of operational mode information.

A remote controller includes a touch screen, a communicator, and a processor. The processor controls control a first user interface to be displayed on the touch screen, identifies a signal which is received through the communicator while the first user interface is displayed on the touch screen, and controls a second user interface to be displayed on the touch screen based on the received signal. The second user interface performs a function which is different from that of the first user interface.

A remote controller of an image processing apparatus includes: a touch screen which displays an input menu; a menu processor which processes the touch screen to display respective input menus corresponding to at least two modes among a control mode of the image processing apparatus, a character input mode and a handwriting mode; and a controller which controls the menu processor to display the input menu of the mode corresponding to a selection signal when the selection signal for the mode is received.

A music audio control and distribution system in a location, comprising a first wireless music audio device connected to a local network, the network operably connecting the music audio device with at least one of: (1) a music audio player or (2) a music audio output device, and with a remote music audio source operably connected to the local network. The location of the local network is one of (a) a home, (b) an office, and (c) an automobile. The system also includes a second music audio device comprising at least one of (i) a music audio player or (ii) a music audio output device. The second music audio device is also connected to the local network and is controllable by the first wireless music audio device.

A wireless network includes a tunable RF transmitter in wireless communication with a master node to transmit at a first slave frequency; a tunable RF receiver in wireless communication with the master node to receive at a second slave frequency; and an RF oscillator to communicate with the RF receiver and the RF transmitter an RF oscillator frequency to determine and tune the first and second slave frequencies. The RF oscillator is configured to receive calibration information including time information or frequency information, or both, from a reference node. The RF oscillator frequency of the RF oscillator is tuned based on the calibration information from the reference node to enable communication between the slave node and the master node at the tuned RF oscillator frequency.

An audio control and distribution system in a location, comprising a first wireless media device connected to a local network, the network operably connecting the media device with at least one of: (1) a media player and (2) an audio output device, and with a remote media source operably connected to the local network. The location of the local network is one of (a) a home, (b) an office, and (c) an automobile. The system also includes a second media device comprising at least one of (i) a media player and (ii) an audio output device. The second media device is also connected to the local network and is controllable by the first wireless media device.
