A valve clearance measuring assembly includes a panel having a first side, a second side, a forward edge and a rearward edge. The forward edge is extendable between a valve tip and a rocker arm. The first and second sides of the panel each are planar and orientated planar with respect to each other. A head includes a central member and a pair of arms. The arms extend in a generally same direction with respect to each other to define a space between the arms. The panel is attached to the arms and traverses the space. The forward edge is in static communication with the arms such that the forward edge is in a linear configuration as the forward edge traverses the space.

A golf club includes a club head having a volume of greater than about 360 cm.sup.3 and a mass less than 200 g. A shaft attachable to the club head has a tip end, a butt end, and a shaft balance point distance, BP.sub.s, as measured from the butt end, of no more than 19 inches. And the golf club has a mass less than 300 g.

An assembly comprises a support including a plurality of individual sections. A scale is disposed on the support. The scale extends in a longitudinal direction and has a measuring graduation for position measurement at least in the longitudinal direction. A plurality of fastening devices are configured to fasten the scale to the support. The fastening devices are disposed on the individual sections of the support.

A measuring device is adapted for measuring a change of linear dimension of a shaft body of a bearing device along an axis due to thermal expansion. The measuring device includes a stationary seat and a strain unit. The strain unit includes an actuator and a strain member. The actuator is adapted to be mounted to the shaft body, and is movable relative to the stationary seat along the axis as a result of the change of linear dimension of the shaft body. The strain member is deformable, is secured to the stationary seat and is connected to the actuator such that movement of the actuator along the axis results in a force applied to the strain member which deforms the strain member.

A centering device for centering a rotor shaft of a generator to a gearbox shaft of a gearbox in a genset assembly is disclosed. The centering device comprises a clamp assembly configured to be oriented on the rotor shaft and the gearbox shaft wherein the clamp assembly is further configured to be tightened to force the rotor shaft to coaxially align with the gearbox shaft. A method of using the centering device in a genset assembly to coaxially align the gearbox shaft with the rotor shaft of a generator is disclosed.

A device and method for identifying a center of a striking face of a golf club head are disclosed. The center determining device includes a device body having a central opening defined through a first surface of said device body and a second surface opposite said first surface. A first dimension indicator including a pair of first indicator jaws and a second dimension indicator including a pair of second indicator jaws may be disposed on said device body. A first adjuster and a second adjuster are operable to adjust said first separation distance said pair of first indicator jaws and a second separation distance between said second indicator jaws. When the pair of first indicator jaws and the pair of second indicator jaws are equally spaced around the heel, toe, topline, and sole edges of the striking face, the central opening is aligned with the center of the striking face.

The disclosure presents templates that can be useful in construction. Embodiments of the templates include a face, and two or more indicators. The indicators are located at one or more predetermined intervals on the face, and each indicator defines a window. Each window is of a predetermined length, and each indicator is coded to indicate that each indicator is located at one of the one or more predetermined intervals.

An image measuring apparatus includes an imager that acquires an image of a measurement target object, a touch panel display that displays the image acquired by the imager and accepts touch input operation of specifying a position in the displayed image, and an edge detector that searches for and detects an edge present in a predetermined range around the in-image specified position specified by a user's touch input operation in the image displayed on the touch panel display. When edges are found in a vicinity of the specified position, the edge detector causes a control object for selecting each of the edges to be displayed on the touch panel display not only in an aspect that prevents a wrong edge from being selected through the touch operation but in an aspect that allows visual recognition of a correspondence between each of the edges and a corresponding control object.

Various embodiments may include a measuring device for three-dimensionally sensing elongate cut-outs comprising: an assembly for positioning and fixing on an elongate cut-out of a body; and a 3-D measuring head connectable to the assembly to be aligned with the elongate cut-out for the respective 3-D surface measurement of the elongate cut-out.

A system for assessment of dimensional variation of an electro-chemical battery cell during charge/discharge cycling, including a test fixture configured to position thereon a battery cell. The test fixture includes a pressure plate configured to apply a force to the battery cell. The test fixture also includes a reaction plate disposed parallel to the pressure plate and configured to sandwich the battery cell between the reaction plate and the pressure plate. The test fixture additionally includes an elastic member assembly configured to facilitate adjustment of the force applied to the battery cell. The system additionally includes an electronic hardware device configured to regulate an electrical current applied to the battery cell. The system further includes a contact displacement sensor configured to detect change in the battery thickness.
