Abstract: A transponder is disclosed to receive a wireless electromagnetic query signal and transmit a corresponding wireless electromagnetic response signal. The transponder comprises a first coil and at least one further coil that function as antennas to receive the wireless electromagnetic query signal and generate separate wired electrical incoming signals. An axis of the first coil and an axis of the at least one further coil are differently aligned in space, and each coil is associated with at least one means for limiting the voltage of the respective incoming signal. The separate wired electrical incoming signals are rectified and converted to current signals. The peak values of the current signals are detected and compared, such that a control signal is generated to identify one coil between the first coil and the at least one further coil that has a larger peak value of current.

Abstract: 2.1. A new design configuration of an RF-transceiver front end is proposed.2.2. The Power Amplifier (PA) output stage of the transceiver comprises a cascode circuitry of N-type transistors with open-drain-configuration. The cascode-transistor is acting as a common-gate-transistor, whose gate is controlled to block the transmitting-(TX) path.The Low Noise Amplifier (LNA) input stage uses a common-gate configuration of a p-channel MOS-transistor that is controlled by the voltage at the bulk terminal. Lifting the bulk potential of this PMOS-transistor above its source potential disables the receiving-(RX)-path.2.3. This design allows low cost implementation for TDMA-RF-transceivers especially for Bluetooth-Solutions. The number of external components is reduced. No additional TX/RX switch is required. The same port and the same matching elements for the antenna's bandwidth adaptation are used for both, the TX-path and the RX-path.

Abstract: 1. Method and device for contactless sensing rotation and angular position using orientation tracking. 2.1 To improve the accuracy and possible resolution of a magnetic positioning system, a method and a device using a special tracking technique is proposed. 2.2. The method and the device are using multiple magnetic field sensing elements at different positions below a magnetic target. The sensed signals are used to select or combine the sensing elements for a best approach to the actual orientation of the magnet. This allows putting out the related orientation of the approach as a coarse value and the remaining displacement as a fine value. 2.3. A device using this method allows highly accurate measurement of angular positions controlling or tolerating the placement of a magnet as the input source.

Abstract: A micromechanical rate-of-rotation sensor for detecting a rate of rotation about a sense axis includes a substrate, a detection unit, means for generating a rotational oscillation of the detection unit about a drive axis which is orthogonal to the sense axis, and a central suspension means rotatably coupling the detection unit to the substrate in a fulcrum of the detection unit. The central suspension means is configured to permit the detection unit to perform a detection movement about a detection axis orthogonal to the sense axis in the form of a rotational oscillation about the central suspension means. The sensor also includes at least two second suspension means coupling the detection unit and the substrate for providing a response behavior specific to rotation about at least one of the drive axis and the detection axis.

Abstract: The invention relates to a microgyroscope for determining rotational movements about an x and/or y and z axis, comprising a substrate, several oscillating masses (4, 5), springs for fastening the oscillating masses (4, 5) to the substrate, drive elements for vibrating at least individual ones of the masses in an oscillatory manner in the x-y plane in order to produce Coriolis forces when the substrate is rotated, and sensor elements for defecting deflections of the masses (4, 5) on account of the Coriolis forces produced. At least individual ones of the masses (4, 5) are arranged in two groups. The masses (4, 5) of both groups can be jointly induced by the drive elements to carry out an oscillating primary movement in the plane of the x-y axis. The masses (4) of the first group are arranged on the substrate in such a manner that they allow movement starting from the x-y plane. The masses (5) of the second group are arranged on the substrate in such a manner that they allow movements perpendicular to the oscillating primary movement in the plane of the x-y axis.

Abstract: The invention relates to a microgyroscope for determining rotational movements about an x, y or z axis. At least one anchor is fastened to a substrate. A plurality of, in particular four, masses which oscillate radially with respect to the anchor are fastened to the anchor by means of springs. Drive elements are used to vibrate at least individual ones of the masses in an oscillatory manner in the x or y direction in order to produce Coriolis forces when the substrate is deflected. Sensor elements are used to detect deflections of the masses on account of the Coriolis forces produced. The oscillating masses are connected to at least one further, non-oscillating mass which can, however, rotate together with the oscillating masses on the substrate about the at least one anchor. A further sensor element is associated with this further mass.
