Abstract: The invention relates to an anti-theft alarm system for vehicle wheels. The system comprises at least one wireless measuring module for determining kinetic state information characterizing the kinetic state of a vehicle wheel on the basis of acceleration measurement. The wireless measuring module is further configured to be attached to the vehicle wheel, to generate a wireless data transfer signal on the basis of the kinetic state information and transmit the wireless data transfer signal. The system further comprises at least one wireless central processing unit, which is configured to receive the wireless data transfer signal and execute a predetermined alarm function when the wireless data transfer signal fulfils predetermined conditions.

Abstract: A light fitting comprises at least one replaceable module (112, 114), and each module (112, 114) comprises at least one light source (106 to 110). Each module (112, 114) comprises a controller (102, 104) for compensating for a change in light intensity resulting from the aging of at least one light source (106 to 110) by adjusting the electric power to be supplied to said at least one light source (106 to 110) as a function of time in a predetermined manner.

Abstract: The invention relates to a monitoring system for vehicle wheels and a wireless measurement module. The wireless measurement module is configured to be attached to a vehicle wheel and comprises: an acceleration measurement unit for determining acceleration information associated with wheel motion of the vehicle; a state determination unit for determining a value of at least one parameter characterizing a characteristic or state of the vehicle wheel by using the acceleration information; and a module communication unit for communicating the value of said at least one parameter by means of a wireless communication signal.

Abstract: A method of controlling an external radio frequency amplifier of a radio telephone and a control system therefore. The power amplifier of the transmission side of the radio frequency amplifier is controlled to turn on and off, on the basis of at least one control signal (BENA1, BENA2) entering the radio frequency amplifier separate from a signal to be transmitted from the radio telephone. The control signal (BENA1, BENA2) contains information about the starting and ending instant of transmission.

Abstract: A dual mode transmitter circuit is disclosed including a non-linear high-power amplifier having an amplification that can be adjusted and a linear high-power amplifier. A first switch and a second switch are connected to the input and output of the linear, high-power amplifier. An amplification-adjustable, high-frequency transmitter control amplifier is connected to the input of the non-linear high-power amplifier. Apparatus for measuring transmission power such as a directional coupler is connected to the second switch, and a duplex filter is connected to the directional coupler. A power level control circuit is responsive to the measured transmission power from the directional coupler and to a power level signal. The power level signal is representative of the desired output power of the transmitter.
