A system for use in measuring an end play of a wheel hub assembly includes a follower configured to extend through an opening in a cover connected to a wheel hub. The cover covers the wheel hub such that the cover inhibits access to an end of a shaft of the wheel hub assembly, and the follower is configured to contact the end through the opening. The follower is received in a holder engageable with the cover such that the follower is movable relative to the cover and the holder to allow the follower to extend from the holder to contact the end of the shaft. A frame has a cavity receiving a measurement probe extending outwardly from the cavity. The probe contacts the follower and is configured to measure movement of the follower to determine endplay of the bearing assembly on the shaft. The frame includes a plurality of legs extending from the frame to a hub mounted on the shaft and coupled to the bearing to support the frame relative to the hub.

Apparatus for measuring bone depth for determining the length of fastener to be employed in medical treatment of the bone includes an elongated inner bone probe having a bone-engaging portion and a plurality of first manually-engageable elements secured thereto. An outer sleeve overlies at least a portion of the inner bone probe and is movable with respect thereto. A second manually-engageable element is secured to the outer sleeve. The first and second manually-engageable elements may be generally ring-shaped, so as to facilitate insertion of a user's fingers. The apparatus is structured to have the bone-engaging portion of the inner bone probe pass through an opening in the bone and engage the distal exterior surface in intimate contact as a result of the first manually-engageable elements being engaged and urged away from the bone. The outer sleeve is moved generally toward the bone so as to achieve contact between the distal end of the outer sleeve and the proximal exterior surface of the bone. A reading of desired fastener length may then be made. Other embodiments of the gauge employing different configurations of the two main components and additional functional features, as well as adaptors, which facilitate retro-fitting structural features, of the present invention into prior art devices. Associated methods are provided.

A diamond element (10) having a convex surface is disclosed, the convex surface including a spherical segment for which the maximum peak to valley deviation from a perfect spherical surface is less than about 5 μm. The diamond element (10) may be a solid polycrystalline diamond material and/or may comprise base material which is coated with diamond. Alternatively or in addition, the RMS deviation from a perfect spherical surface may be less than about 500 nm, or the RMS roughness less than about 30 nm. A diamond element (10) with a radius of curvature less than about 20 mm is also disclosed. In one aspect a diamond element (10) having a conical half-angle greater than about 10° is described. Diamond elements (10) of this type are intended for use as metrology tips.

A device and method for measuring the pantoscopic tilt of a lens installed in a frame, the device comprising an orientation sensor for measuring pantoscopic tilt and an attachment member to attach the device to a lens. The method comprises marking a center of the pupil on a lens while a patient is wearing the spectacles, attaching a measurement device at the marked center of the pupil point and while the device is attached to the lens, reading the pantoscopic tilt value from the device while the patient is wearing the spectacles in a natural position of the head for looking at the horizon.
摘要:
A vehicle parking assist system of a wireless battery charger for positioning a capture resonator or receiving plate attached to a vehicle over a source resonator or charging pad residing on a parking surface under the vehicle. The system includes a target positioned relative to the source resonator at a location that is viewable by an operator of the vehicle while the vehicle is being parked. The vehicle is equipped with a plurality of light sources attached to the vehicle, and the light sources are oriented so that when the vehicle is properly positioned, light beams from the light sources impinge on the target at one or more predetermined locations, or converge at some predetermined location on the target.

Provided is an apparatus for measuring outer diameters of fuel rods of a nuclear fuel assembly, in which the fuel rods are standing upright and are used in a light water reactor. The apparatus includes a support unit fixed to a floor at a lower portion thereof so as to be kept insulated from vibrations caused by external forces, a measuring unit mounted on the support unit and moving up and down to measure the outer diameters of the fuel rods, and a transducer cooperating with the measuring unit, converting the measured outer diameters of the fuel rods into electrical signals, and sending the converted signals to the outside. Thus, the apparatus moves up and down to measure the outer diameters of the fuel rods, so that it can accurately check abnormalities in the outer diameters of the fuel rods.

A device for measuring anatomical dimensions of animals, and particularly the angle of inclination between the occlusal plane of an animal, defined by the contact surface between its upper and lower dental arches, and the alternative reference planes passing either through the anterior sagittal point and the temporomandibular joints, or through the anterior sagittal point and the eyes of the animal includes an element of contact with the animal, at least one first movable member attached revolvingly to the contact element around a first axis of rotation, and at least one graduated scale situated on the contact element, or on the first movable element to enable the measurement of their relative rotation. The contact element also includes a locator plate sized to fit inside the animal's mouth between its upper and lower dental arches, and to be aligned with the occlusal plane.
