Patent number: 7896098Abstract: Power tools are taught that may include, for example, means for detecting impact sounds generated, e.g. by a hammer strikes an anvil or by oil pulse from an oil unit. The detecting means may include a receiver (30) adapted to selectively convert sound within a narrow frequency range into electric signals. Preferably, the impact sounds fall within the narrow frequency range of the receiver (30). A processor 38 may be utilized to control the motor (22) in order to stop the rotation of the hammer when a pre-determined number of impact sounds has been detected by the detecting means. In addition or in the alternative, various means for setting various operating conditions are taught, including dials 34, sound sensors 30, keypads and remote control devices 250. Further, means for performing maintenance condition status checks are taught.Type: GrantFiled: January 17, 2006Date of Patent: March 1, 2011Assignee: Makita CorporationInventors: Hitoshi Suzuki, Masahiro Watanabe

Patent number: 7886573Abstract: This application is directed to a shock sensor mounted in an electronic device. The shock sensor includes both active and passive shock detection methods that allow a technician to determine whether the electronic device was subjected to a shock event that exceeded an impact threshold level. The shock sensor may include shock detection contacts that form an electrical circuit that remains open in the absence of a shock event that exceeds an impact threshold level. In response to a significant shock event, a movable component or substance of the shock sensor may move from a first position to a second position, thereby closing the electrical circuit formed by the shock detection contacts. The change in circuit may be detected and used to provide active indication of whether the electronic device has been subjected to a substantial shock event. In addition, the shock sensor may be observed to passively determine whether the electronic device has been subjected to a substantial shock event.Type: GrantFiled: April 22, 2009Date of Patent: February 15, 2011Assignee: Apple Inc.Inventors: Stephen P. Zadesky, Fletcher R. Rothkopf

Patent number: 7886574Abstract: A projection device is configured by connecting a projectile supporting part to a spring supporting frame with multiple coil springs. The projectile supporting part is pulled while deforming the coil springs; a projectile is projected by accelerating the projectile supporting part, supporting the projectile, with restoring forces of the coil springs; and the projectile is collided with a test piece supported by the test piece supporting base. Thereby, it is possible to check a state of collision of the projectile with the test piece or how the test piece is damaged thereby. Since the projectile is projected with the restoring forces of the deformed coil springs, the collision test apparatus is simple and compact in structure, low-cost, and easy-to-handle in comparison with projection of a projectile with compressed air.Type: GrantFiled: October 8, 2008Date of Patent: February 15, 2011Assignee: Honda Motor Co., Ltd.Inventor: Akira Kaneko

Patent number: 7818991Abstract: A guide release system for use in an impact test of a motor vehicle includes a first guide releasably coupled to a first portion of the motor vehicle to guide the first portion of the motor vehicle towards a test barrier. The system also includes a second guide releasably coupled to a second portion of the motor vehicle to guide the second portion of the motor vehicle towards the test barrier. The second guide is displaced a distance from the first guide. The system further includes an actuator that releases the first guide and the second guide substantially simultaneously to enable the motor vehicle to freely contact the test barrier.Type: GrantFiled: July 26, 2007Date of Patent: October 26, 2010Assignee: Chrysler Group LLCInventors: Todd L. Saunders, Maynard L. Robinson, David L. Tiihonen
