1. A system for wireless operation comprising:
- a receiver; and
a mobile remote control unit having an acceleration sensor and a control unit, the mobile remote control unit operable to wirelessly transmit control signals to the receiver,wherein the control unit is configured to;
receive and evaluate measurement signals of the acceleration sensor;
determine a connection quality between the mobile remote control unit and the receiver;
block the transmission of at least some of the control signals when a decision criterion determined by the measurement signals of the acceleration sensor and the connection quality is exceeded;
determine, from the measurement signals of the acceleration sensor, a relative translocation of the mobile remote control unit;
correlate the relative translocation with a change in the connection quality; and
use the correlation as the decision criterion so that the transmission of at least some of the control signals is only blocked when a reduction in the connection quality is detected in conjunction with the determined relative translocation exceeding a permitted movement.

Abstract
A system for wireless operation includes a receiver and a mobile remote control unit having an acceleration sensor and a control unit. The mobile remote control unit is operable to wirelessly transmit control signals to the receiver. The control unit is operable to receive and evaluate measurement signals of the acceleration sensor, determine a connection quality between the mobile remote control unit and the receiver, and block the transmission of at least some of the control signals when a decision criterion determined by the measurement signals of the acceleration sensor and the connection quality is exceeded.

14. A method for wirelessly transmitting control signals to a receiver using a mobile remote control unit, the method comprising:
-
determining a translocation of the mobile remote control unit with respect to a reference position using a measurement signal of an acceleration sensor; determining a connection quality between the mobile remote control unit and the receiver; determining a decision criterion on the basis of the measurement signal of the acceleration sensor and the connection quality; and blocking the wireless transmission of the control signals when the decision criterion is exceeded, wherein determining the decision criterion includes; correlating a change of the connection quality with the determined translocation; and using the correlation as the decision criterion so that the wireless transmission of the control signals is only blocked when a reduction in the connection quality is detected in conjunction with the determined translocation exceeding a permitted movement. - View Dependent Claims (15, 16)
