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: A plastic joint for a selector pin that can be moved around at least one swiveling axis comprises an inner, first joint element and an outer, second joint element for mounting in a device. The first joint element includes a first plastic material with axially opposite end sections, the second joint element includes a second plastic material with borings that lie in the swiveling axis in which the end sections are held, forming the swiveling axis. The joint elements are spanned by a plastic sealing element as a seal. The joint elements can be produced individually or as a unit via injection molding processes.

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 remote controlled industrial equipment, e.g., a construction unit with at least one transmitter, which includes at least a second receiver that is operable parallel to a first receiver. The receivers are arranged with parts of the industrial equipment widely displaced apart from one another such that a control connection from the transmitter to at least one of the receivers can be established for the purpose of converting control signals of the transmitter into working movements of the industrial equipment. The receivers can therefore establish a continuous control connection up to the respective receiver that finally controls the working units of the industrial equipment, whereby simple and safe control remains ensured even under unfavourable external conditions.

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 process for the control of a plurality of industrial, construction or mobile hydraulic machines, such as cranes, travelers and similar machines, by means of n remote control units (S1 . . . Sn), allocates the remote control units to k concentrators (K1 . . . Kk), whereby the number (k) of concentrators is smaller than the number (n) of remote control units. Preferably, only a single concentrator (K) is provided. The concentrator (K) provides the signals from the remote control units with a suitable address and transmits them via a common data network, such as the power grid (AC), to which the concentrator (K) and control devices (ST1 . . . STm) for the m power units of the industrial machines to be controlled are connected in such a way that a signal is recognized by its address and converted into the control signal for activation of the respective power unit.

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.

Abstract: A manual control device with a control stick (joystick) whose output signal is proportional to the angular deflection of the control stick has transducers that step the output signal in such a way that the manual control device imitates or simulates the switching behavior of a N-stage manual control device. For that purpose, analog or digital electronic means associate with the output signal of the manual control device, depending on its value, one among N different voltage values, whose number and potential difference may be predetermined. The advantages of an analog manual control device (few mechanical components, cheap production) are thus combined with the advantages of a N-stage manual control device (adjustment information for the user, wider field of application in industrial control processes).
