摘要:
Athletic performance monitoring systems and methods, many of which utilize, in some manner, global positioning satellite (“GPS”) data, provide data and information to athletes and/or to equipment used by athletes during an athletic event. Such systems and methods may provide route information to athletes and/or their trainers, e.g., for pre-event planning, goal setting, and calibration purposes. Such systems and methods optionally may provide real time information to the athlete while the event takes place, e.g., to assist in reaching the pre-set goals. Additionally, data and information collected by such systems and methods may assist in post-event analysis for athletes and their trainers, e.g., to evaluate past performances and to assist in improving future performances.

The swim device includes a wrist unit system wearable on a wrist and a hand, at least one hand sensor unit that is wearable on a hand, and at least one foot sensor unit wearable on a foot. The wrist unit system includes a wrist unit and at least one pressure sensor. The wrist unit includes an integrated circuit chip (ICC) computer; a battery; an alarm, a display and housing with input buttons, and a wrist band with an embedded antenna. The hand/foot sensor unit includes an integrated circuit chip (ICC) computer with a battery. The pressure sensor is attached to a cap that is worn on the first segment of a finger or big toe in such a manner that the pressure sensor faces the water-bound side of the finger or big toe.
摘要:
Articles such as optical displays and protective films, comprising a (e.g. light transmissive) substrate having a surface layer comprising the reaction product of a mixture comprising a hydrocarbon-based hardcoat composition and at least one perfluoropolyether urethane additive. The surface layer exhibits low lint attraction in combination with high contact angles. Hardcoat coating compositions comprising a perfluoropolyether urethane additive and a silicone(meth)acrylate additive are also described.
摘要:
A method for determining probe tip diameters with improved accuracy and reliability that includes performing a routine for determining probe tip diameter multiple times with the arm of the coordinate measurement machine in different machine positions. Diameter values associated with each of the calibration routines may be combined in a manner that provides more accurate diameter measurements.

A test sample is provided for testing performance of measuring and monitoring equipment for production lines, for example for foodstuffs or pharmaceuticals, and in particular, contamination monitoring equipment employing X-rays and/or metal detectors to spot foreign bodies in packaged products. The test sample may comprise a laminated card enclosing a standardised test piece such as a metal particle of specified size. The card or other sample bears at least one identification containing a barcode, readable by an optical scanner. To test the equipment, a card is placed on a product package passing through the equipment, the optical scanner reads the barcode to confirm that the correct test sample has been submitted, and the results for the test sample are recorded in a computer log. If the results do not match those expected from the particular test sample submitted, the equipment fails the test and requires recalibration or repair.

The subject invention concerns methods revealing surface imperfections on an object comprising the steps of: coating the surface to be inspected with a composition comprising an opaque, water-dispersible liquid, sufficiently surface-adherent and with surface-wetting properties as to create a gloss finish, at least before the liquid dries, on the restored area; inspecting the surface to check for imperfections; and removing said composition with water. The method may also include a step of marking the surface, through the wet composition layer, to indicate the location of imperfections discovered. Also described are compositions and delivery systems suitable for carrying out the method comprising aqueous dispersions of a pigment and a resin, especially a polysaccharide resin.

A system for determining a distance of travel of a brake cylinder piston includes a brake cylinder having the brake cylinder piston, a pressure transducer operationally coupled to the brake cylinder and configured to determine a pressure measurement within the brake cylinder, and a control module of an electrically controlled pneumatic (ECP) brake control system. The control module is operationally coupled to the pressure transducer and configured to convert the pressure measurement within the brake cylinder determined by the pressure transducer into at least one of a displacement time of the brake cylinder piston, an equalization pressure within the brake cylinder, a pressure build-up time within the brake cylinder, a pressure leakage from the brake cylinder, or any combination thereof. The control module determines the distance of travel of the brake cylinder piston based on at least one of the displacement time of the brake cylinder piston, the equalization pressure within the brake cylinder, the pressure build-up time within the brake cylinder, the pressure leakage from the brake cylinder, or any combination thereof.
摘要:
A system and process for managing measurement data and generating production and engineering drawings from measurements obtained from a sample population parts to generates and parametrically update engineering and production drawings from measurement data of actual parts. The system and process provides efficient allocation of measurement resources to generate engineering drawings and models. The resources are allocated in a manner that eliminates and reduce time required for producing and generating usable engineering models and drawings.

A method is proposed for measuring tools on a machine tool with a measuring device, wherein by means of a movement of a spindle of the machine tool the measuring device is temporarily positioned at a measuring point on the machine tool in order to carry out one or more measurements, the measuring point differing from a spindle mount. Furthermore, a measuring apparatus is proposed which is embodied in such a way that the measuring device can be positioned at a measuring point on the machine tool for a measuring operation by means of a spindle movement of a machine tool, said measuring point differing from a spindle mount.
摘要:
A method for measuring dimensions between selected points on a side of interest in objects selected for measurement by an optical measuring system comprising a flatbed scanner and a connected computer system through acquiring a reference image to provide corresponding image distance errors; and also acquiring a measurement object image. Deviation curves are provided as the basis for determining deviation errors in the measurement object image. Corrected measurement object image distances are formed through combining the deviation errors in the measurement object image distances with the corresponding measurement object image. These corrected measurement object image distances are used to determine distances between chosen pairs of those selected locations.
