Abstract: A caliper for measuring the size of an object, especially the thickness of an object with non-planar surfaces. After measured, the caliper can be removed from the object without changing the measured value. The caliper includes a scale ruler, a vernier slidably disposed on the scale ruler, a first jaw fixedly connected to the scale ruler and a second jaw pivotally connected to the vernier. In normal state, the second jaw is kept in a position in alignment with and in parallel to the first jaw, whereby the caliper can be used to measure the object in a common manner. After measured, the second jaw is rotated to another position, permitting the caliper to be removed from the measured object.

Abstract: A femoral tibial spreader (100) for spreading adjacent bones includes a radial measurement gauge (111) for providing incidia corresponding to an amount of force being applied to the forward ends (105,106) of the femoral tibial spreader (100). The femoral tibial spreader (100) may be used, for example, to separate the femur (301) and tibia (302) during knee surgery. The radial measurement gauge (111) may be used to determine an amount of force being applied to the femur (301) and tibia (302), for example, by the medial and arterial ligaments. Two handle members (104,109) are squeezed together, which causes the forward ends (105,106) to open. A biasing member (110) allows a measurement extension (108) to pivot towards a handle member under tension, thereby providing a measurement of force applied by the ligaments.

Abstract: This invention provides an angle gauge that, when used in conjunction with a caliper or other linear measuring device, improves both the precision and ease with which angles can be measured and set by allowing the user accurately to measure and set angles in fractions of degrees. Using the gauge, an angle formed by the gauge may be determined or set by reference to the linear distance measured by the caliper. Calculations or tables can be used to convert the linear measurements into the angle setting or measurement with great accuracy, or the capacity to calculate the angle corresponding to the linear measurement can be built (i.e. programmed) directly into the device.

A spring urges a stop member pivotally mounted within the housing to an extended position in which the stop member projects through the top opening. In use, an individual slides the gauge beneath a frame portion of a race car at a location to be measured, causing the stop member to contact a portion of the race car frame, depressing the stop member against the bias of the spring into the housing to a depressed position in which the distance from a bottom surface of the housing resting on the ground or a floor to the uppermost extending portion of the stop member corresponds to the car frame height at the particular location.

Abstract: An electronic fat gauge includes a main body and a clamping lever pivotally mounted on the main body. The clamping lever includes a shorter depressing arm and a longer measuring arm extended from a middle pivot portion of the clamping lever in opposite directions. When the shorter depressing arm is depressed, the longer measuring arm is caused to open by a wide angle relative to the main body for conveniently clamping a fatty area of a user's body between the measuring arm and the main body. The open angle of the measuring arm is converted into a signal through a variable resistor connected to the middle pivot portion of the clamping lever, and the signal is further converted by a control circuit into a value of measuring result for showing in a liquid crystal display and viewing by the user.

Abstract: A system for generating a solid model of the sidewall of the container. A mandrel selectively holds the container in first and second locations. In the first location, a non-contact measurement apparatus utilizing a digital camera produces digital information for generating a three dimensional sidewall surface profile of the container based upon shadow edge detection. In the second position, a contact measurement apparatus produces information for generating a three dimensional sidewall thickness map of the container. A computer collects the information from the contact and non-contact measurement apparatuses and produces an overall solid model of the sidewall of the container based upon sidewall surface profile and sidewall thickness. The computer generates can tilt, diameter, can ovality, and can squarity information.
