摘要： An improved sliding bearing apparatus and method utilize a snap-in polymer bearing insert having one or more identically shaped locking lugs, each of which are configured for locking engagement with a corresponding depression in a bearing housing, to thereby lock the bearing insert in place against relative movement either radially or axially with respect to the bearing housing. In a free-standing state, the insert may have a variety of shapes including cylindrical, non-cylindrical, or be flat and planar. An insert for a closed bearing is configured such that it may be trimmed to form an insert for an open bearing.

摘要： At least one parameter of a signal is determined, wherein the signal is a sinusoidal signal including noise, wherein the parameter includes at least one of a frequency of the signal, and an angle of a phase of the signal. The frequency of the signal is determined iteratively based on a linear relationship among the frequency of the signal, samples of the noise, and samples of the signal using a statistical correlation among the samples of the noise. During a current iteration the statistical correlation is updated based on the frequency of the signal determined during a previous iteration, and the samples of the signal are updated with values of the signal during a current period of time.

摘要： A power module is proposed to package an electronic system having flip chip power MOSFET devices. The power module includes a front surface cover board and a multi-layer printed circuit laminate bonded thereto. Notably, the front surface of the printed circuit laminate includes recessed pockets each having printed circuit traces atop its floor. Inside the recessed pockets are power MOSFET and other circuit components bonded to the printed circuit traces. As the circuit components are encased inside the power module, it features a low profile, an increased mechanical robustness and EMI/RFI immunity. Additionally, some circuit components can be provided with a front-side bonding layer that is also bonded to the front surface cover board to realize a double-side bonding to the interior of the power module. Methods for making the low profile power module are also described.
