The present disclosure provides a device control method, which comprises capturing, by a portable device, a first image of a specific area containing a number of electronic devices connected to a communication network; transmitting a connection signal to a selected electronic device on a device list containing all the electronic devices connected to a communication network; determining whether the selected electronic device is in the first image captured based on whether a response has been received from the selected electronic device; identifying the selected electronic device on the device list and the relative position of the selected electronic device on the first image captured upon determined that the selected electronic device is in the first image; and continuing the device identification process until all the connected electronic devices on the device list has been verified, to identify the relative positions of all electronic devices contained in the first image.

The present invention relates to a method for contactlessly establishing a coupling between a medical apparatus (e.g., a hemodialysis apparatus or a peritoneal dialysis apparatus) and a remote control apparatus. An optical coupling signal is exchanged between the involved communication entities, in order to establish bijective, data-processing coupling between the remote control apparatus and the medical apparatus. Only after successful coupling is a remote control procedure initiated for remote control of the medical apparatus.

There is provided a wireless battery system reconcilable with unsuccessful communication due to interference from an external wireless instrument or radio wave reflection or shielding under a surrounding physical environment. A wireless battery system allocates a cell controller to a cell, detects a cell state, and wirelessly communicates a cell state detected by a cell controller to a battery controller. During the wireless communication, the battery controller transmits a beacon to the cell controller and specifies a duration for radio wave environment measurement and a frequency to be measured as a condition. The cell controller performs radio wave environment measurement under the specified condition and then returns a measurement result along with the cell state to the battery controller.

An alert system includes an audio speaker or video display, and a communications unit. The communications unit is retained and supported by a power and data unit, and is configured to access data sources that include at least one of schedule information, environmental information, news reports, fire/police alerts, weather statements/information, and user-specific information, and to communicate with the audio speaker based upon the accessed data sources. The communications unit is configured to network with a computing device associated with a first user. The communications unit is configured to access the one or more data sources as defined by user-specific parameters associated with the first user. The first user is identified based upon a user ID associated with the networked computing device. The communications unit is configured to direct the audio speaker or the video display to issue an alert in response to the one or more accessed data sources.

The present invention provides a data transmission method, apparatus and system. The method includes: in a detection period, receiving a first pilot signal sent by an unmanned aerial vehicle (UAV), the first pilot signal being a downlink signal obtained by modulating a useful signal at a preset candidate frequency, and the preset candidate frequency including a frequency in a same frequency band and/or different frequency bands; determining a downlink operating frequency from the preset candidate frequency according to the first pilot signal; sending a first feedback signal to the UAV, the first feedback signal including information about the downlink operating frequency; and receiving downlink data sent by the UAV and modulated at the downlink operating frequency. In this way, frequency detection in a same frequency band and/or across frequency bands is implemented to select an optimal preset candidate frequency as an operating frequency, so that data transmission between a UAV and a remote control is more stable, interference from an external signal is reduced, and quality of data transmission between the UAV and a ground end is improved.

In one embodiment, a remote controller for a vehicle includes at least one control element for controlling operation of at least one aspect of the vehicle when the vehicle is in a remote-control mode; an actuator connected the at least one control element for controlling a position of the at least one control element when the vehicle is in an autonomous operations mode; and a processing system for receiving a first control signal from the vehicle indicative of a state of operation of the vehicle. In operation, the processing system generates a second control signal to the actuator to cause the actuator to control a position of the control element such that it corresponds to and indicates the state of operation of the vehicle.

The invention relates to a system composed of an apparatus to treat a fluid and a handheld device, wherein the apparatus has a communication unit with a radio antenna and the handheld device has a communication unit with a radio antenna and both communication units can exchange data with each other by means of radio communication, and the apparatus has a control unit, which can detect at least one status parameter of the apparatus and generate a signal which is dependent on the status parameter and can transfer it via the communication unit of the apparatus to the communication unit of the handheld device.

A remote starting system and method are provided for self-propelled work vehicles having work attachments supported from a main frame thereof. Cameras are arranged with respective fields of vision proximate to the work vehicle, and a communications unit is configured to exchange messages with a user device via a communications network. A local or remote controller is configured to receive first user input comprising a remote startup request for the work vehicle from the user device, and to automatically detect parameters respectively associated with predetermined remote startup conditions, at least one of the parameters comprising images obtained from the cameras. The images are transmitted to the user device, responsive to which second user input is received comprising remote startup confirmation from the user device via the communications network. Responsive to at least the second user input, engine startup is automatically controlled for the work vehicle.

A remote control unit of a remote control device wirelessly transmits a first instruction signal or a second instruction signal instructing to operate a solenoid valve, to a solenoid valve control unit. The solenoid valve control unit receives the first instruction signal or the second instruction signal and generates a first drive signal or a second drive signal on the basis of the received first instruction signal or the received second instruction signal, respectively. The solenoid valve is of a double solenoid type, and includes a first solenoid to which the first drive signal is supplied and a second solenoid to which the second drive signal is supplied.

A control device is used to autonomously program a remote control device based on media device information received from a media device. The control device selects a program code set based on the media device information. The control device transmits a program code set to the remote control device and a test command. The test command causes the remote control device to transmit a program code from the program code set based on the test command. The control device monitors the media device and verifies that the program code associated with the test command controlled the associated function of the media device.
