Abstract: Computer input devices include a detector adapted to detect relative movement of an input member in x-, y-, and z-dimensions relative to a base point in a base plane, and a controller adapted to send a signal to an associated computing device based at least in part on the relative movement of the input member. Associated computing devices, software, and methods are also disclosed.

Abstract: Table saw blade guards, splitter assemblies, attachments, accessories, and table saws including the same. The splitter assemblies include a splitter and a blade guard that is coupled to the splitter. The blade guards include a top guard. In some embodiments, the top guard is configured to be a hold-down guard. In some embodiments, the top guard is pivotally coupled to the splitter. In some embodiments, the top guard is adjustably coupled to the splitter. In some embodiments, the top guard is secured in a fixed orientation relative to the splitter. In some embodiments, the top guard includes a portion that is secured in a fixed orientation to the splitter and a portion that is pivotal relative to the splitter.

Abstract: Woodworking machines are disclosed having cutting tools for cutting workpieces. The machines include a detection system adapted to detect one or more dangerous conditions between a person and the cutting tool. The machines also include a mechanism having a moveable component adapted to move upon detection of the dangerous condition by the detection system. Movement of the moveable component contributes to one or more of the following actions to mitigate or prevent injury to the person: deceleration of the cutting tool, retraction of the cutting tool, and placement of a barrier over at least a part of the cutting tool. An actuator is adapted to move the moveable component at a high acceleration when the dangerous condition is detected.

Abstract: Woodworking machines are disclosed having cutting tools adapted to cut workpieces. The machines include a safety system adapted to detect one or more dangerous conditions between a person and the cutting tool, and to stop movement of the cutting tool upon detection of the dangerous condition. At least part of the safety system is housed in a removable cartridge substantially sealed against entry of sawdust.

Abstract: A table saw having an adjustable blade, a detection system to detect contact between a person and the blade, and a brake mechanism to engage and stop the blade upon detection of contact between the person and the blade is disclosed. The saw includes a brake positioning system that adjusts the position of the brake mechanism to maintain the brake mechanism in an operative position relative to the blade as the position of the blade is adjusted. The saw also may include a retraction system that urges the blade downward, away from a user, upon detection of contact between a person and the blade. The retraction system may include a releasable gear. The saw may be constructed so that the blade is adjustable up and down around a pivot point downstream of the blade relative to the feed direction.
