Abstract:
There is provided a battery wireless 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.
Abstract:
A relay apparatus according to the present invention includes reception means for receiving a remote operation request, storage means for associating first identification information related to a controlled-side communication apparatus or a controlled-side user that is remotely operated with second identification information related to a control-side communication apparatus or a control-side user that remotely operates the controlled-side communication apparatus to store the first identification information in association with the second identification information as permission information, determination means for comparing the first identification information and the second identification information included in the permission information with the first identification information and the second identification information included in the remote operation request, respectively, to determine whether to allow the remote operation, and transmission means for generating a control message to transmit the control message upon determination in the determination means that the remote operation is allowed. According to the configuration, it is possible to start remote operation without requiring the controlled-side user to start up the server by himself/herself in response to the request for the remote operation.
Abstract:
According to a related remote control system, a remote control processing may occur even during an operated side terminal is in an emergency situation. An operated side terminal transmits, to a relay server, reception status information identifying a reception status for a remote control. Upon receiving a remote control request from an operating side terminal, the relay server determines whether or not a remote control is permitted based on access permission information which includes a pair of an operating side terminal permitted to remote control and an operated side terminal, and additionally, determines, based on reception status information, whether or not the operated side terminal currently accepts the remote control. Based on the determination outcomes, the relay server transmits, to the operated side terminal, a control message related to the remote control, based on which the operated side terminal provides a service.
Abstract:
A system for transmitting commands and a video stream between a remote controlled machine (1) such as a drone and a ground station (5) comprises a two-way link (3, 4) between the machine and ground station, at least partially implementing a cellular communication network (3), said two-way link being provided by means of a cellular modem (2, 17) on the machine side and conveying a compressed video stream (7) produced by a camera (11) and a video encoding module (12), and information belonging to a group comprising movement control commands (9) and flight data or operating characteristics of the remote controlled machine (6), the system further comprising means (20, 22) for managing the two-way link capable of ensuring said link is maintained, taking into account the variability in topology and performances of the link resulting from the implementation of the cellular communication network. Application to long-range drones.
Abstract:
The device according to the present invention is adapted to securely switch off a photovoltaic installation by placing a low-impedance by-pass across the output terminals of the solar panel of said photovoltaic installation. In one embodiment, the device according to the present invention is further adapted to discharge the capacitance between each output terminal of said solar panel and ground.
Abstract:
Upon receiving a command signal transmitted from a remote controller (100), based on contents of the received command signal, a setter (121b) of an electrical apparatus (12) sets a time interval for prohibition of operation from an operation terminal (101). During the time interval set by the setter (121b), an operation controller (121a) of the electrical apparatus (12) does not control based on the received command signal, even if a command signal transmitted from the operation terminal (101) is received via a HEMS controller (11).
Abstract:
The invention relates to the remote control for technical devices, comprising a passive RFID transponder which triggers a switch contact in the event of a physical contact of a user, in order to emit information to control the technical device.
Abstract:
The invention relates to methods and devices for exchanging control information in mixed radio systems. Security is added in cases where a user of a first wireless device (102) wants to command a second wireless device (101) to perform a certain action. The first and second wireless devices use different radio systems or standards (e.g. WiFi and ZigBee/802.15.4) but their radios do operate on the same frequency band (e.g. 2.4 GHz). To add security, the second wireless device (101) will only accept certain commands if it can detect that the first wireless device (102) is physically close-by. To prove that the first device (102) is close-by, it emits a predetermined energy pattern, e.g., one or more packets (the contents do not matter, while their lengths/time spacing may) using its radio system. At the same time, the second wireless device (101) measures the energy in one or more of its overlapping radio channels to detect that the first wireless device (102) is close by and execute the commanded action.
Abstract:
Die Fernsteuerung mit einem Gehäuse (1), einem in dem Gehäuse angeordneten Batterieträger (4) und einem Elektronikträger (3), der mit einer Leiterbahnplatte (2) verbunden ist, ist so aufgebaut, dass der Elektronikträger (3) parallel zur Ebene der Leiterbahnplatte (2) gegenüber dem Gehäuse (1) linear verschiebbar ist. Zwischen der Leiterbahnplatte (2) und dem Elektronikträger (3) ist eine Verriegelungsfeder (5) angeordnet, die mit einem Halteschenkel (10) zwischen der Leiterbahnplatte (2) und dem Elektronikträger (3) gehalten ist und mit einem gegenüber dem Halteschenkel (10) abgewinkelten Federschenkel (11) durch eine Öffnung (13) des Elektronikträgers hindurchgreift. Der Federschenkel (11) liegt am Boden (20) des Gehäuses (1) federelastisch an und hat einen Rastschenkel (12), der von dem Federschenkel (11) absteht. Am Boden (20) des Gehäuses (1) ist eine Rampe (23) angeordnet, die bis zu einer Vertiefung (24) ansteigt. Die Vertiefung (24) weist eine Rastkante (27) auf, mit der der Rastschenkel (12) in Kontakt bringbar ist.
