Saw guard

A saw guard for attachment to a riving knife of a table saw includes a body portion having an elongated shape. The body portions defines a guard portion configured to cover a portion of a saw blade and an attachment portion. The attachment portion extends from the guard portion and defines a slot configured to receive the riving knife. The saw guard further includes an anchor piece connected to the body portion and arranged at least partially in the slot. The saw guard further includes an attachment assembly connected to the body portion and arranged at least partially in the slot and separated from the anchor piece. In a first configuration, the anchor piece and the attachment assembly may define a two-point attachment between the saw guard and the riving knife. In a second configuration, the attachment assembly may permit release of the saw guard from the riving knife.

Saw guard and methods of use thereof

A piezoelectric rotary optical mount including a clamp including a first hole to hold a hollow member, wherein a contact between the clamp and the hollow member generates a coefficient of friction; a bias element adjacent to the first hole to apply a force to control rotational movement of the hollow member by adjusting the coefficient of friction; and a piezoelectric element to actuate the bias element to apply the force. The clamp may include a housing body including a first end and a second end, wherein the first hole extends in a first axis through the housing body to accommodate the hollow member; a pair of elongated cutout regions extending from the first hole towards the second end to define the bias element; and a second hole adjacent to at least one of the cutout regions to accommodate the piezoelectric element.
