| Number | Title | Issue Date |
| 7049934 | Data carrier for transmitting data with different repetition frequencies A data carrier is configured to monitor the power of a received signal from a base station, and to vary its “Aloha” transmission based on the power of the received signal. The time period, or repetition frequency, associated with the Aloha transmission is contro... | 05/23/2006 |
| 6996115 | Network comprising a plurality of network nodes for media access checks The invention relates to a network comprising a plurality of intercoupled network nodes. Controlled by a bus guardian the network nodes transmit messages during a respectively assigned time slot and receive messages from other network nodes outside this time slot. E... | 02/07/2006 |
| 6992565 | Electronic communications system An electronic communication system for a vehicle, including a base station which is accommodated in the vehicle and at least one portable data carrier which is arranged to exchange data signals with the base station. A first coupling link is formed at least partly b... | 01/31/2006 |
| 6975175 | Charge pump The present invention relates to a charge pump, in particular for use in a tuning system including a phase-locked loop, for generating currents, including a current amplifier, wherein the current amplifier includes a translinear circuit. ... | 12/13/2005 |
| 6957382 | Receiving circuit for receiving messages signals The invention relates to a receiving circuit for receiving message signals, having a first sampler for converting the message signal into a first sampled signal by a first sampling method, having at least one second sampler connected in parallel with the first sampl... | 10/18/2005 |
| 6949963 | Line driver with current source output and high immunity to RF signals Line driver for a LIN-bus. The line driver has a current source output transistor (T1) for pulling down the LIN-bus wire (LB) to ground (GND). The LIN-bus wire (LB) is connected to a positive supply voltage (VBAT) through a pull-up resistor (R1). The o... | 09/27/2005 |
| 6943632 | Frequency locked loop, clock recovery circuit and receiver A frequency locked loop comprising a controllable oscillator (1) and a control signal generator (2) for generating a control signal (Sc) for the oscillator (1) from a reference signal (Sref) and an output signal (So) from the oscillator (1 | 09/13/2005 |
| 6919775 | Network coupler For a network coupler for network users in a network comprising at least two lines, a simultaneous data and energy transfer is ensured in that the network coupler is formed in such a way that it is suitable for data transfer via the two lines (1, 2) of the ne... | 07/19/2005 |
