Abstract: A method for operating a radio remote control system having a transmitting unit and a receiving unit, composed of: following the termination of a radio connection between the transmitting unit and the receiving unit, modifying at least one transmitting or receiving parameter of the transmitting unit or the receiving unit with respect to a standard value in such a way that the establishment of a new radio connection is only possible if the distance between the transmitting unit and the receiving unit does not exceed a predetermined value; and following the establishment of a new radio contact with the modified parameter in effect, resetting the respective parameter to the standard value.

Abstract: An injection molded element in combination with at least one electrical contact element embedded in the injection molded element. The injection molded element forms a wall element of an electric or electronic device.

Abstract: A control element for a device, specifically a push-button or switch, is provided on at least part of its visible surface with a luminescent substance, which is admixed to the synthetic material of the control element. The luminescent substance provides, over a certain period of time, a luminous density with decreasing intensity, which compared to areas in the vicinity and/or applied symbols, produces an at least sufficiently visible contrast in order to make the control element stand out recognizably.

Abstract: A marking element for marking the function of a control element of an electric or electronic device with numbers or pictorial symbols. The marking element is composed of a first section composed of a first film having a luminescent layer to be applied to a control area of the control element, and a number or pictorial symbol is provided on the first section.

Abstract: A manual control device composed of: a housing; a joystick; and a joint supporting the joystick in the housing to enable the joystick to pivot about two mutually orthogonal axes relative to the housing. The joint is an elastic molded plastic part composed of an interior portion secured to the joystick, a peripheral portion secured to the housing and a connecting portion extending between, and connecting, the interior portion and the peripheral portion. The interior portion has the form of a first cylinder and the peripheral portion has the form of a second cylinder, the first and second cylinders being concentric with one another when the joystick is in a neutral position. The connecting portion has a frustoconical shape when the joystick is in the neutral position and is stressed when the joystick is pivoted away from the neutral position.

Abstract: A remote control system, particularly for remotely controlling industrial equipment, has a sensor that detects the operator's safety-relevant medical data and transmits them as a control signal to a control circuit in a transmitter or receiver. The control circuit triggers a predefinable control sequence when the value of the control signal exceeds or falls below at least one predefinable value. A malfunction, especially of the “human component” of the total system, can be reliably detected as soon as it becomes safety relevant, i.e., as soon as there is a danger that the operator might no longer be able to control the industrial equipment properly and reliably with the remote control system.
