Abstract: A positioning system (10) for determining location information of/for a mobile radio transmitter (1) comprises an antenna system (2) which includes a plurality of antennas (21) aimed at different directions and arranged on one common antenna carrier (20). The positioning system (10) comprises a receiver system (3) electrically connected to the antennas (21) and configured to receive via each of the antennas (21) a radio signal (7) transmitted by the mobile radio transmitter (1). The positioning system (10) further comprises a processing circuit (4) electrically connected to the receiver system (3) and configured to calculate the location information of/for the mobile radio transmitter (1) based on the radio signal received at each of the antennas (21). The location information includes at least angular direction of the mobile radio transmitter (1) with respect to the antenna system (2).

Abstract: An RFID receiver (1) comprises an antenna (11) configured to receive a radio signal (20) from an RFID transmitter (2) and to generate an electrical signal (110) from the radio signal (20) received from the RFID transmitter (2). A decoder circuit (10) is connected to the antenna (11) and configured to extract from the electrical signal (110) generated by the antenna (11) data bits encoded in the electrical signal (110). The decoder circuit (10) comprises an analog-to-digital converter (12) connected directly to the antenna (11) and configured to generate a digital input signal (13) from the electrical signal (110) generated by the antenna (11). A bit extractor (14) is connected to the analog-to-digital converter (12) and configured to extract the data bits from the digital input (13) signal generated by the analog-to-digital converter (12).

Abstract: A known device for increasing the functional reliability for a hydraulic circuit of a hydraulic clutch having a pressure reservoir (25) and a release cylinder (5) which comprises a primary piston (14) and a secondary piston (16). A compensation volume is developed in the sense that when the vehicle is at a standstill and the parking brake released, an unintentional release of the clutch is prevented. A pressure-monitoring/pressure-supply device (28) is used for determining a reference operating pressure and establishes a static pressure which, in case of any system error, only allows displacement of the secondary piston (16) such that the contact pressure of the clutch discs, against one another, is still sufficient to maintain the vehicle at a standstill.

Abstract: A method for clutch actuation at low temperatures for a motor vehicle having a hydraulically actuatable clutch, below a predetermined temperature a situation-dependent pre-opening of the clutch is executed when a braking is probable.

Abstract: The invention relates to a method for controlling a pressure supply device in a hydraulic circuit, especially in a hydraulic circuit in an automatic gearbox which comprises an hydraulic pump, a pressure control valve and a consumer. The hydraulic pump is controlled if the system pressure falls below a specific lower threshold value and is switched off if a specific higher threshold value of the system pressure is reached or exceeded. In the data on the system pressure is not available, the current system pressure is calculated.

Abstract: A known device for increasing the functional reliability for a hydraulic circuit of a hydraulic clutch having one pressure reservoir and one release cylinder which comprises a primary piston, a secondary piston and a compensation volume is to be further developed in the sense that when the vehicle is at a standstill and the parking brake released, an unintentional release of the clutch is prevented. According to the invention there is used for the purpose a pressure-monitoring/pressure-supply device (28) which determines a reference operating pressure and establishes a static pressure which in case of system errors allows only a displacement of the secondary piston (16) such that the contact pressure of the clutch discs against each other is still sufficient to hold the vehicle at a standstill.
