20140150570 | SYSTEM AND METHOD FOR SETTING MEASUREMENT FORCE THRESHOLDS IN A FORCE SENSING CALIPER - An electrically powered caliper is provided which includes a scale member, a slider, a displacement sensor, a force sensing arrangement and a signal processing portion. The signal processing portion is configured to receive a force signal and indicate a respective force corresponding to the respective position of the slider. Force data is acquired comprising a plurality of respective forces corresponding to respective positions of the slider. The signal processing portion defines an acceptable measurement force range defined by at least a minimum force threshold that is determined such that it exceeds a compensation force corresponding to at least one force component included in the force signal that is independent of user variations of the measurement force. It may analyze acquired force data to identify pre-contact data, and set the minimum force threshold for a current measurement procedure based on that pre-contact data. | 06-05-2014 |
20150247717 | WHEEL ASSEMBLY FOR MOVING CALIPER JAW WITH REPEATABLE FORCE - A compliant wheel assembly is provided for moving a caliper jaw relative to a caliper spar. The wheel assembly includes a rotary bearing member, a rotary actuation member and a compliant coupling element. The rotary bearing member is coupled to the caliper jaw and may engage the caliper spar. The rotary actuation member is actuated by a user to apply a measuring force. The compliant coupling element is configured to compliantly couple the rotary actuation member to the rotary bearing member. Using the compliant wheel assembly, a user is able to apply a more consistent amount of measurement force than could typically be achieved with a conventional rigid thumb wheel in caliper. In one implementation, a displacement indicator may also be provided that is responsive to the rotational displacement between the rotary bearing and actuation members for indicating an amount of measurement force that is being applied. | 09-03-2015 |
20150276366 | FLEXIBLE MOUNT FOR COUPLING FORCE ACTUATOR TO CALIPER JAW - A flexible mount is provided for coupling a force actuator to a caliper jaw. The flexible mount includes a first mounting portion for being coupled to the caliper jaw, a second mounting portion for being coupled to the force actuator, and a flexible element (e.g., a parallel flexure) coupled between the first and second mounting portions. When a force is applied to the force actuator (e.g., by a user pushing on a thumbwheel) along the measuring axis direction, the flexible element flexes to generate a measuring force that is applied to the caliper jaw. The use of the flexible mount results in more control and a better feel for a user when attempting to exert control to provide a desired amount of force during a measuring process. The flexible mount may also utilize a fastening configuration that is compatible with existing mounting features on existing caliper jaws. | 10-01-2015 |

20110317171 | PHOSPHOR WHEEL CONFIGURATION FOR HIGH INTENSITY POINT SOURCE - A phosphor point source element comprises a disk substrate and light emitting phosphor particles arranged on the substrate to provide a circular operational track having a desirable tightly packed particle arrangement adjacent to a flat operational surface of an operational track region. The operational track region is rotated while illuminated to provide a high intensity point source of radiation. The tightly packed particle arrangement may be achieved by spinning the phosphor particles in a cavity between a fabrication plate and the substrate, to compress the phosphor against the fabrication plate at the periphery of the cavity, or by mechanically compressing the phosphor. An adhesive binding agent may permeate the phosphor particles and be cured to maintain the tightly packed arrangement. A window element may support and/or protect the operational surface, in some embodiments. | 12-29-2011 |
20110317396 | PHOSPHOR WHEEL CONFIGURATION FOR HIGH INTENSITY POINT SOURCE - A phosphor point source element comprises a substrate and light emitting phosphor particles arranged on the substrate to provide a circular operational track having a tightly packed particle arrangement adjacent to a flat operational surface of an operational track region. The operational track region is rotated while illuminated at a point to provide a high intensity point source. The tightly packed particle arrangement may be achieved by spinning the phosphor particles in a cavity to compress the phosphor on the substrate at the periphery of the cavity, or by other mechanical compression. The tightly packed phosphor arrangement may either be compressed against a forming element that bounds the cavity, or machined, to provide a flat operational surface. An adhesive binding agent that permeates the phosphor particles may be cured to fix the tightly packed arrangement. A window element may support and/or protect the operational surface, in some embodiments. | 12-29-2011 |
20150059480 | Method for Validating a Workpiece Measurement in a Dimensional Metrology Hand Tool - A method for validating a workpiece measurement in a hand-held spatial dimension measurement metrology tool comprises vibrating a portion of the metrology hand tool using the vibration excitation element; sensing a vibration signature using the vibration sensor configuration; identifying a valid contact state between the metrology hand tool and the workpiece based on a vibration signature criterion; identifying a valid seating state based on a measurement stability criterion applied to a set of dimensional measurements of the metrology hand tool; and indicating that a dimensional measurement is valid for a dimensional measurement that is obtained when the valid contact state and the valid seating state occur simultaneously. | 03-05-2015 |
20150178484 | Remote Accessory Management in a Programming Environment for a Progammable Metrology System - A programming environment for a metrology system comprises a remote accessory managing portion that connects to a remote device (e.g., a user's smart phone or tablet) that is not normally associated with the metrology system. The remote accessory managing portion may comprise an accessory communication portion configured to communicate with a remote device, an accessory authorization portion configured to authorize the remote device for connection to the programming environment, and an accessory data management portion configured to receive and store a set of reference information data from the authorized remote device. The remote accessory managing portion is configured such that when an authorized remote device sends the set of reference information data to the accessory data management portion, it is automatically associated with a current part program instruction representation indicated in at least one of the program editing environment and a user interface of the remote device. | 06-25-2015 |
