摘要： A measuring probe includes a stylus having one or more contact portions; a detection element configured to detect a movement of the stylus based on a contact made by the contact portions; a signal processing portion configured to process a signal from the detection element to output a measurement signal; and a stylus motion mechanism. The stylus motion mechanism includes a first motion portion configured to enable motion of the stylus from a rest position in a positive axial direction when a corresponding force in the positive axial direction is applied by a contact of a contact portion of the stylus with a workpiece; and a second motion portion configured to enable motion of the stylus from the rest position in a negative axial direction opposite to the positive axial direction when a corresponding force is applied by a contact of a contact portion of the stylus with a workpiece.

摘要： The object of the present invention is a device for measuring skinfold thickness digitally instrumented for reading the thickness of skin folds and possessing wireless data communication capability with a remote station (for example, a personal computer) in which is installed a software application integrating a database. The developed device utilises working principles distinct from those available in the market, in particular uses a constant force actuator (11) integrated in the device handle (12A), whose primary function is to impose a constant contact pressure between the end tip faces (1A and 1B) and the skinfold under measurement. Another characteristic is related to the increase of the opening limit of the end tips (1A and 1B) by using a large centre distance for the jaws pivot axes, jointly with a cam for compensating the change in the force arm length, the constant force actuator and the orientation mechanism of the clamping faces of the end tips, whereby the application of a constant pressure throughout the whole measuring range is accomplished.

摘要： Systems and methods of providing a magnetically coupled ground reference probe for use with test equipment (e.g., digital multimeters (DMMs)). The magnetically coupled ground reference probes disclosed herein may be used instead of a typical test probe or alligator clip. A magnetically coupled ground reference probe may be provided which includes an insulative housing surrounding a conductive magnet (e.g., permanent magnet, electromagnet). The magnet may autonomously retract into a cavity of the insulative housing when not coupled to a ground reference so that the magnet does not contact a high potential source when being handled by the operator. In at least some implementations, at least a portion of the insulation material of the housing may be compressible to allow the magnet to come into physical contact with a ground reference surface while providing a sufficient creepage and clearance path.

摘要： An approach controller (234) of a coordinate measuring instrument enables a position control loop (RP) and drives an actuator (133) so that a force sensor (1) is brought to a close position under a position control. When recognizing that the force sensor (1) reaches the close position, a contact controller (235) controls a switch (227) to enable a force control loop (RF) and drives the actuator (133) to bring the force sensor (1) into contact with a workpiece under a force control.

摘要： A dual stage scanning instrument includes a sensor (60) for sensing a parameter of a sample (90) and coarse and fine stages (80,70) for causing relative motion between the sensor (60) and the sample (90). The coarse stage (80) has a resolution of about 1 micrometer and the fine stage (70) has a resolution of 1 nanometer or better. The sensor (60) is used to sense the parameter when both stages cause relative motion between the sensor assembly (60) and the sample (90). The sensor (60) may be used to sense height variations of the sample surface as well as thermal variations, electrostatic, magnetic, light reflectivity or light transmission parameters at the same time when height variation is sensed. By performing a long scan at a coarser resolution and short scans at high resolution using the same probe tips at fixed relative positions, data obtained from the long and short scans can be correlated accurately.
