Abstract:
In certain embodiments, a remotely controllable television has an energy converter that receives light energy from a laser in a remote controller and converts the light energy to electrical energy. A remote control code interpreter that is receives a turn-on code from the remote controller. The electrical energy from the energy converter is used to supply power to the remote control code interpreter. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
Abstract:
An icon/text interface remote controller and particularly a remote controller incorporating with a display device which displays an icon/text menu interface to allow users to make selection mainly includes a touch panel, a button switch, a power supply, a power control circuit and a wireless emission circuit that incorporate with the display device. Users can see options of the icon/text menu on the display device to do remote control operation in a more user-friendly fashion.
Abstract:
A field transmitter includes field device circuitry configured to measure or control a process variable. A first process control loop terminal is configured to couple to a two-wire process control loop which carries a loop current. A second process control loop terminal configured to couple to the two-wire process control loop. A switching regulator has an input and an output. The output is coupled to the transmitter circuitry and arranged to provide power to the transmitter circuitry. A variable voltage source having an input electrically coupled to the first process control loop terminal, and a voltage output coupled to the input of the switching regulator and a control input. The voltage output is a function of the control input.
Abstract:
System including at least one master unit and a plurality of slave units, wherein the master unit and the slave units have means for performing communication via radio frequency channels. The at least one master unit including means for transmitting control signals to the slave units, and the slave units are each provided with a unique address and are each associated with a controllable device. The at least one master unit includes means for executing a sequential transmission of control signals to at least one of the slave units upon activation of a function control key.
