摘要： A device for measuring force components formed from a single crystal material, wherein the device comprises at least one cantilever beam inclined to a wafer plane normal and formed in one piece with a mass body, which mass body provides a mass of inertia. The mass body has a first and a second major surface which are substantially parallel with a wafer plane. A mass body cross section presents a portion which is substantially symmetrical along a centrally (in the thickness direction) located plane parallel with the wafer plane. Disclosed is also a method for its production and an accelerometer comprising at least one such device. The device allow for a more compact 3-axis accelerometer.

摘要： Provided are a method, system, and device directed to a receive path for a node in a communication system such as a Radio Frequency Identification (RFID) system. In one aspect, the receive path includes a filter operable in multiple modes and configurable to have different bandwidths in the various modes of operation. For example, in one mode, the filter samples a DC component while configured to have a relatively wide bandwidth. As another example, the filter may be operated in another mode to hold the sampled DC component while the filter is configured to have a zero or close to zero bandwidth. As yet another example, the filter may be operated in still another mode to filter received signals and cancel the sampled DC offset from the received signals while configured to have a relatively narrow bandwidth. Additional embodiments are described and claimed.
