摘要： A method of fabricating a MEMS device includes depositing an expandable material into a first recess of a cap wafer. The cap wafer includes a plurality of walls that surround and define the first recess and a second recess. The cap wafer is bonded to a MEMS wafer including a first MEMS device and a second MEMS device. The first MEMS device is encapsulated in the first recess, and the second MEMS device is encapsulated in the second recess. The expandable material is then heated to at least an activation temperature to cause the expandable material to expand after the first recess has been sealed. The expansion of the expandable material causes a reduction in volume of the first recess.

摘要： A wireless charging system for use in vehicles includes power transmitting coils which are used for resonant power transfer to power receiving devices in the vehicle. The system includes a detection system for detecting power receiving devices in the vicinity of the transmitting coils so that only the power transmitting coils having objects detected nearby are activated. The system also includes a tuning circuit that enables power transmitting coils to be tuned with respect to each other to increase the power delivery range or detuned with respect to each other to decrease interference between coils.

摘要： A circular saw includes a motor, a blade axle operably connected to the motor and configured to support a blade, and a footplate configured to support the motor above a workpiece at a reference position in which the blade is positioned with zero bevel. The circular saw further includes a blade guard that is rotatable about the axis of rotation from a closed position to an open position and includes an anti-snag structure with a front end portion and a trailing edge portion. The anti-snag structure includes a linear leading edge located between the front end portion and the trailing edge portion, and is configured such that when the footplate is at the reference position and the blade guard is in the closed position, a line extending through the axis of rotation and perpendicular to the footplate when viewed from a side elevational view passes through the linear leading edge.

摘要： Locking mechanisms are provided for locking the position of a miter gauge assembly to a sliding table of a table saw. The mechanisms are biased to a locking position and this bias can provide a sensible indication that the lock has been engaged. The locking mechanisms are configured to engage the guide bar of the miter gauge assembly at different locations along the length of the guide bar, particularly by engaging a series of spaced apart engagement notches. The locking mechanism thus allows the miter gauge assembly to be locked at several positions along the length of the sliding table, from a fully inboard position to a position in which the miter gauge assembly projects beyond the end of the sliding table. The locking mechanism is provided in different embodiments with manually actuated components that can be push/pull, pivoting, rotating or sliding.

摘要： The invention relates to a heat sink (1) for an electric machine, which heat sink has at least one cooling channel (7), which adjoins an interior (3) surrounded by the heat sink (1). The heat sink (1) is characterized in that the heat sink (1) is designed as a single-piece plate (5) bent into a closed ring, in the case of which plate two opposite abutting surfaces (19, 21) are connected to each other in a fluid-tight manner in the region of a joint (17), wherein a plurality of closed channels (7) extend in the plate (5), which channels extend at an angle to the circumferential direction of the ring in such a way that adjacent channels (7) lead into each other in the region of the joint (17) and thus form a continuous, spiral channel, which extends in a plurality of spiral turns from an axially front end (22) to an axially rear end (24) of the annular heat sink (1). In particular, the plate (5) of the heat sink (1) can be economically extruded and then brought into a shape suitable for the heat sink (1) by means of bending and axial offsetting. The heat sink (1) can be produced in a simple and economical manner and enables efficient cooling of an electric machine while requiring a minimal installation space.
