摘要： A saw includes a surface defining an opening therein, a plate structure configured to be attached to the saw below the surface, and an arm attached to the plate structure about a first shaft. A blade is configured to be engaged with the arm at a location spaced from the first shaft. The blade extends through the opening when the saw is in a normal operating position. The saw includes a firing mechanism including a barrel end portion having a bore defined therein and an extendable piston at least partially positioned within the bore. The barrel end portion is attached to the plate structure. The extendable piston engages the arm during its extension and causes the arm to pivot about the first shaft when the firing mechanism is activated by an activation signal. The pivoting of the arm causes the blade to be moved downwardly below the surface.

摘要： A power cutting tool, such as a table saw, comprising a sensing system for detecting certain conditions with respect to an exposed blade of the power cutting tool is disclosed. Several embodiments of the sensing system comprise at least one sensor located above the blade and positioned to (1) monitor one or more volume zones adjacent the blade, (2) detect when an object enters one or more of the zones, and (3) trigger a reaction system in response to the detection. Another embodiment uses an optical sensor to measure the height of objects approaching the blade to detect an increase in the height beyond a predetermined threshold. Still another embodiment uses an optical distance sensor to detect the occurrence of a work piece lifting from the table top which can indicate that a kick-back condition is imminent. The reaction system can be triggered when such a condition is detected.

摘要： A man-machine interface device is provided which employs rigid links interconnected by measured revolute joints to provide the position of a hand relative to a reference location, such as a desk, keyboard or chair. By proper selection of kinematic structure, and by placing one of the joints near the elbow and extending one of the links along the line of the forearm, translation of the joint-link structure is minimized, hence the undesirable perception of friction and inertia are also minimized. When Hall-Effect sensors are used as the revolute joint goniometers, the permanent magnets of neighboring joints are placed in the same link so the effects of magnetic field interference can be calibrated out. A hand-sensing joint-link device as described herein can produce data which is more noise free, at a higher sample rate, with less latency and more robust that competing electromagnetic, optical and ultrasonic sensing technologies, without adding much encumbrance. The output from the hand-sensing device may be used to produce a graphical "virtual hand" on a computer monitor which mimics the movement of the measured physical hand. The hand-sensing joint-link device may also be used with a finger-sensing joint-link device to provide data on the movements of the fingers and hand. When a right and left finger- and hand-sensing joint-link devices are used, the wearer can use both hands to manipulate virtual objects on a computer monitor.
摘要翻译：提供了一种人机界面装置，其使用通过测量的旋转接头互连的刚性连杆，以提供手相对于参考位置（例如桌面，键盘或椅子）的位置。通过适当选择运动学结构，并且通过将一个接头放置在肘部附近并且沿着前臂的线延伸一个连杆，使关节连杆结构的平移最小化，因此不期望的摩擦和惯性感知也是最小化。当使用霍尔效应传感器作为旋转关节测角器时，相邻接头的永磁体被放置在相同的连杆上，从而可以校正磁场干扰的影响。如本文所述的手感传感联合装置可以以更高的采样速率产生更无噪声的数据，具有更少的等待时间和更强的竞争性电磁，光学和超声波感测技术，而不增加太多的负担。来自手持感测装置的输出可以用于在计算机监视器上产生模拟测量的物理手的运动的图形“虚拟手”。手感传感联接装置还可以与手指感测联合连接装置一起使用以提供关于手指和手的运动的数据。当使用右手指和左手指和手感联合装置时，佩戴者可以使用双手来操纵计算机监视器上的虚拟对象。

摘要： A toilet ventilation device includes a housing that defines an air inlet aperture and an air outlet aperture. Within the housing are an air movement apparatus for drawing air into the device, a filter for removing malodorous elements in the air, and a radar sensor for activating the air movement apparatus in response to the presence of a user and, optionally, deactivating the air movement apparatus when the user leaves. The toilet ventilation device is configured and arranged to draw air, using the air movement apparatus, from the toilet, through the air inlet aperture, into contact with the filter, and out the air outlet aperture. In one embodiment, the toilet ventilation device is disposed over the overflow conduit of the toilet to draw air from the bowl of the toilet, through the overflow conduit, and into the toilet ventilation device. The entire toilet ventilation device is preferably disposed within a tank of a toilet.
