A wireless systems and methods are disclosed for establishing a continuous real-time data link communicating flight data of a small UAV to a first smart device over a wireless network. An airborne wireless sensor system is adapted to be removably attached to the UAV. The airborne wireless sensor system has a sensor module for sensing UAV flight data, a communication module for establishing the wireless data-link network and transmitting the sensed UAV flight data the smart device. The smart device may have a software application which permits the user to define data formats for display which may them be communicated to the airborne sensor system to use in building the data pages transmitted to the smart device. Smart devices such as smart phones, smart watches, tablet computers and the like are contemplated to be used.

According to one configuration, a remote controller device wirelessly controls a remote media system. The remote controller device includes multiple selectable control buttons, multiple optical sources, and controller hardware. Each optical source individually back-illuminates a respective selectable control button of the multiple selectable buttons. The controller hardware selectively activates different groupings of the multiple optical sources depending upon a current operational mode of the remote media system. For example, a respective user of the remote controller device selects a particular button of the remote controller device corresponding to the first operational mode. The remote controller device, in turn, transmits a wireless signal to the remote media system to control the remote media system to the first operational mode. Rather than illuminating all buttons, the remote controller device then back-illuminates only a relevant group of multiple selectable control buttons applicable to the first operational mode.

A remote controller is mounted detachably on a wall surface of a toilet room. The remote controller is provided with a housing, an operation button unit, and a control substrate. The housing is mounted on the wall surface such that a back surface portion is substantially parallel with the wall surface. The operation button unit is arranged on the housing. The control substrate is arranged inside the housing and controls a flush toilet in response to operation received by the operation button unit. The housing is formed so as to become thicker toward the lower side.

The present disclosure illustrates a code activation device used to transmit an activation signal to a back-end device, so as to activate the back-end device. The code activation device comprises a sensing module and a processing module. The sensing module comprises a sensor unit, and the sensor unit generates sensing signals according to a preset action of a trigger object. The processing module connected to the sensing module receives the sensing signals, generates a sensing beat according to interval periods between the sensing signals, and determines whether the sensing beat matches a preset beat, wherein the processing module generates the activation signal when the sensing beat matches the preset beat.

An air conditioner includes a first Doppler sensor that transmits a first electric wave of first power, a second Doppler sensor that transmits a second electric wave of second power less than the first power, and a controller that controls an operation of the air conditioner on the basis of a detection signal of the first Doppler sensor and a detection signal of the second Doppler sensor.

Provided is a remote control system with which leakage current flowing in a switch can be reduced so that power consumption can be reduced. The remote control system includes a portable information terminal, a server, and an electric device. The on/off of the switch included in the electric device is controlled using information transmitted from the portable information terminal to the server. The switch includes a transistor formed using a semiconductor whose band gap is larger than that of single crystal silicon in a channel formation region.

Devices and systems are provided for controlling electronic devices using a mobile remote control device. A mobile remote control device provides an interface to control a plurality of electronic devices. The mobile device has a unique identifier, and the electronic device transmits a presentation of a remote control to the mobile device. A user of the mobile device controls the electronic device by operating the virtual remote control displayed on the mobile device. The user may further define his or her custom remote control. The user may define batches of commands, or macros that transmit a specific series of commands to one or more electronic devices. Proximity and motion of a mobile device may be used as an input, such that the electronic devices are programmed to react in specific ways depending upon the position and movement of the user of the mobile device.
