Abstract: A tool includes a housing, a drive assembly including an output shaft extending from the housing such that a tool element for performing work on a workpiece is attachable to the output shaft, and a bushing disposed within the housing. The bushing rotatably supports the output shaft. The bushing is impregnated with lubricant such that the bushing is self-lubricating, and the bushing has an impregnation ratio between about 5% and about 25%.

Abstract: A computer that includes a processor and a memory can determine a final trajectory for a vehicle by determining a candidate trajectory of a first object based on a detected second object. The candidate trajectory can be input to a reachable polyhedral marching processor to determine dynamic occupancy polyhedrals based on a shape of the candidate trajectory. A reachable tube can be determined based on combining the dynamic occupancy polyhedrals and the final trajectory can be determined based on the reachable tube avoiding the detected second object.

Abstract: A power tool includes a housing having a motor housing portion and a front casing coupled to the motor housing portion. The power tool also includes an electric motor positioned within the motor housing portion, a drive assembly having an output shaft to which a tool element for performing work on a workpiece is attachable, and a powdered metal bushing disposed within the front casing that rotatably supports the output shaft.

Abstract: A water craft able to offer fast rescue includes a water craft provided with a pressurization pump and a high pressure air reservoir to have air pressurized and poured into the high pressure air reservoir and stored therein. The water craft is formed with a concealed storage space having an uninflated rescue device received therein. The rescue device communicates with the high pressure air reservoir so that the rescue device can be inflated via the high pressure air reservoir. Thus, before inflated, the rescue device can be entirely received in the concealed storage space, letting the water craft have good maneuverability and, after inflated, the rescue device will be ejected out of the concealed storage space for carrying many persons thereon, thus advantageous to carry out rescue mission.

Abstract: The present invention is a 3D/2D convertible color projection display system with two color LCoS panels, which enable the system to project two orthogonal polarized images. When the two images correspond to different view angles, each eye of an observer wearing a pair of polaroid glasses can only see one of the images, creating a 3D stereoscopic effect. When the two images correspond to the same view angle, then the observer, without any special glasses, can watch regular 2D images with multiple primary colors.
