摘要:
The present invention is drawn to a non-contact thermometer that is operable to emit a first light having a first color to create a spot of a first color at a reference target and to detect the temperature of the reference target. The non-contact thermometer is additionally operable to establish a temperature difference threshold. In use, once a temperature difference threshold is selected and once the temperature of the reference target is detected, the non-contact thermometer may detect a temperature of another target. Further, if the detected temperature of the other target is outside of the temperature difference threshold as compared to the temperature of the reference target, the non-contact thermometer is operable to emit a second light having a second color to create a spot of a second color at the other target.

A power hand tool can include a generally longitudinal housing having a first end and a second end. An indicator can be disposed on the housing. A first and a second jaw member can be arranged at the first end wherein one of the first and second jaw members can rotate relative to the other jaw member. A motor assembly can be disposed in the housing and include an output member arranged at the second end. A sensor can be arranged at the second end and configured to sense an electrical field in proximity thereof. The sensor can generate a signal in response to a sensed electrical field. A controller can receive the sensor signal from the sensor assembly and control operation of the indicator in response thereto.
摘要:
A method and apparatus for providing erasable relief images including providing a face surface formed of a temperature sensitive shape memory material. The face surface may be selectively heated to cause the shape memory material to displace and form a predetermined relief image. Alternatively, the shape memory material may be selectively engaged with die elements to form a predetermined relief image. The relief image may be erased by heating the face surface to thereby cause the shape memory material to return to a uniform surface contour, or to soften the shape material sufficiently for it to be engaged and compressed to a predetermined uniform configuration by an erasing element.

A table saw guard assembly for guarding a blade on a table saw is provided. The table saw guard assembly includes a support structure and a hood assembly including at least one of a front curtain, first side curtain, second side curtain and top curtain, wherein each of said curtains are independently moveable and/or removable from the hood assembly. Furthermore, a table saw guard assembly is provided including a quick release mechanism for connecting the hood assembly to the support structure.
