A cutting system including a surgical saw and a blade assembly is described. The blade assembly may comprising a blade bar, a blade head, and a tag. The tag may comprise a memory containing data related to one or more characteristics of the blade assembly. The surgical saw may comprise a saw processor for receiving data from the tag of the blade assembly and be configured to regulate the operation of the saw based on the one or more characteristics of the blade assembly. The one or more characteristic of the blade assembly comprises may comprise a blade assembly length, a blade geometry, and a blade teeth geometry. A method of navigating a surgical saw is also described. The method may comprise attaching a blade to the saw, touching a pointer to reference points on the blade, and determining the position and orientation of a distal end of the blade.

A ball striking device has a head that includes a metal face configured for striking a ball, a rearwardly extending metal band, a top piece, and a bottom piece. The metal band has a first end extending from one side of the face, a second end extending from the opposite side of the face, and a rear portion extending between the first and second ends and defining at least a portion of the rear periphery of the head. The top piece and the bottom piece are non-metallic or substantially non-metallic. The top piece is connected to the top side of the metal band and forms at least a portion of a top side of the head, and the bottom piece is connected to the bottom side of the metal band and forms at least a portion of a bottom side of the head. The top piece and the bottom piece are separated by the metal band.

Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow require a variety of fluid flow components which are tightly packaged within the apparatuses for controlling flow. Servicing the apparatuses requires specialized equipment and methods which enable installation of seals in close quarters in apparatuses which are installed in the field. Seal retainers may be used to retain the seals during assembly of fluid flow components into apparatus for controlling flow.

In an example, the solar tracker has a clamp assembly configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first and second anchoring region. In an example, the support structure is configured from a thickness of metal material. In an example, the support structure is configured in an upright manner, and has a major plane region. In an example, the assembly has a pivot device configured on the support structure, a torque tube suspending on the pivot device and aligned within an opening of the support, and configured to be normal to the plane region. In an example, the torque tube is configured on the pivot device to move about an arc in a first direction or in a second direction such that the first direction is in a direction opposite to the second direction.

A mounting system for securing a sink to a countertop supported by a cabinet is provided. The mounting system includes a receiving structure configured to be supported under a rim of the sink, a bracket having a first portion configured to engage a portion of the cabinet and a second portion configured to engage a bottom of a basin of the sink, a linking member extending between the receiving structure and the bracket, a first connector configured to engage a first end of the linking member and retain the linking member relative to the receiving structure, and a second connector configured to engage a second end of the linking member and secure the bracket against the cabinet and the bottom of the basin of the sink.

An anchor for lightning protection systems includes a base and pad that extend over a sufficient area and a sufficient bearing length to hold in shear and in tension against the weight, shear force, and moment of cables, points, and other components of a lightning protection systems. A universal point mount may be forged to optimize cross sectional area and contact surface area throughout the mounting system. Drilled and tapped to receive a point oriented arbitrarily, the head mounts easily on a horizontal or vertical mounting surface. Apertures and fasteners provide arbitrary positioning of a point at any necessary orientation.

Embodiments are directed to methods and apparatuses for ensuring that mechanisms that are used to position components of an apheresis machine are not broken as a result of rotation of a centrifuge. In embodiments, a safety mechanism is provided that contacts components of the centrifuge and pushes them into a position to ensure that they do not break when the centrifuge is operated at high rpm.

Disclosed herein is a panelboard guard assembly configured to restrict access to a panelboard having a cover and a door defined therein, the cover having first and second side edges. The panelboard guard assembly includes overlapping members that are, at least in some implementations, mutually coupled to each other. The panelboard guard assembly further includes an adjustment mechanism that extends between and couples the members together, the adjustment mechanism facilitating adjustment of the distance between the outer ends of the members.

A mode setting unit sets a parameter setting mode or a work mode. A parameter setting unit sets a plurality of parameter values in the parameter setting mode. A torque estimation unit calculates a tightening torque value by using a detection result from an impact detection unit. In a work mode, a control unit stops a rotation of a motor based on the plurality of parameter values set by the parameter setting unit and in accordance with the tightening torque value calculated by the torque estimation unit. In the parameter setting mode, a work information storage unit stores the tightening torque value calculated by the torque estimation unit during a tightening work according to a user operation, and the parameter setting unit sets the plurality of parameter values based on the tightening torque value stored in the work information storage unit.
