The invention relates to a lifting system and a method for controlling the lifting system, as well as a control system for a lifting system of this type in which an evaluation signal and a control signal are transmitted in order to actuate the lifting devices.

A remote control apparatus is provided. The remote control apparatus includes a directional antenna, a communicator, and a processor configured to, based on a wireless signal being received from an external device through the directional antenna, identify an angle at which the wireless signal is received, based on the angle being within a predetermine range, obtain identification information of the external device by parsing the wireless signal, based on the identification information, identify whether the external device is registered to a server and based on identifying that the external device is not registered to the server, transmit a signal for requesting registration to the external device through the communicator.

A communication system includes a first terminal and a second terminal including an stow part for stowing the first terminal. The first terminal includes a first light emitter that emits infrared light, a first light receiver that receives infrared light, and a first controller. The first controller causes the first light emitter to emit light based on first specifying information upon receiving a pairing request signal via the first light receiver. The second terminal includes a second stow sensor that detects stow of the first terminal, a second light emitter that emits infrared light, a second light receiver that receives infrared light, and a second controller. The second controller causes the second light emitter to emit light based on a pairing request signal in accordance with detection of stow of the first terminal by the second stow sensor and performs control corresponding to the information including the first specifying information.

A method for interacting with a graphical user interface (GUI) of a television operating in a step mode in which movement of a cursor among menu items displayed on the GUI is performed stepwise in accordance with a manipulation of a direction key of the remote controller, the method including receiving, by the television, from a remote controller a signal corresponding to spatial movement of the remote controller detected by the remote controller that instructs the television to switch from (i) the step mode to (ii) a position mode of the GUI in which the movement of the cursor among the menu items is performed in accordance with the spatial movement of the remote controller and switching from the step mode of the GUI to the position mode of the GUI based on the signal.

An automation control system wirelessly controls a safety function of a remote machine. The automation control system comprises a base station and a control receiver. The base station is configured to transmit a control signal for controlling the safety function using a first transmit signal of a first safety channel, and to transmit the control signal using a second transmit signal of a second safety channel. The control receiver comprises: a processor configured to extract a first received version of the control signal from the first received transmit signal, and to extract a second received version of the control signal from the second received transmit signal; and an electrical interface which is connectable with an electrical interface of the machine for controlling the safety function of the machine based on the first received version of the control signal and the second received version of the control signal.

A dynamic panel system for user interaction through visual displays, touchscreens, and selectable buttons is provided. The dynamic panel system may be part of an interactive system that include push buttons having an image conduit to transmit images from an image generation or display element to a visible area of the button. The push button assemblies may contain liquid ingresses configured to direct liquids away from vulnerable components and into a liquid retention cavity, or may be configured such that liquid is returned to a top panel surface of the dynamic panel system. The push button assemblies may further be configured such that liquid is prevented from entering into the assembly at all. The components may be provided in a modular configuration, allowing for easy assembly, replacement, repair, and cleaning.

Systems and methods for using a touch screen are provided herein. In some exemplary embodiments, the touch screen is used as a backup remote to a display and can be used as a 3D pointing device. The touch screen can be an overlay on display surface to control the display. Alternatively, the touch screen can be retractable and ejectable from the display housing. In addition, the touch screen can be wearable. Further, the touch screen can function to control one or more devices, e.g., television, set-top box, DVR, gaming consoles.
