A portable scale that allows travelers to calculate the weight of their luggage and compare the weight against weight limits that are imposed by common carriers. The scale includes circuitry for calculating weight and a memory for storing weight limits. Weight and other information is shown to the user via a display screen. In the preferred embodiment, the scale includes a hook and handle that facilitate weighing suitcases and other objects. The preferred embodiment also includes a digital measuring tape that allows the traveler to check the size of his luggage against size restrictions imposed by common carriers. The scale can also be incorporated into a portable weighing mat, which allows weight to be determined simple by placing the object on the mat. The scale can also be incorporated into the handle of a suitcase wherein the weight of the suitcase is calculated when the suitcase is lifted by its handle.

A system and method for measuring a three-dimensional object uses a number of elongate measuring members that can be displaced with respect to a base in response to a surface of the object. The displaced distances of the elongate measuring members due to the surface of the object are then determined. The displaced distances are measurements of the object surface.

Disclosed is a vehicle wheel measuring apparatus, comprising a push rod, a counter, a wheel, and a gear coupled mechanism, wherein the counter is disposed on top of the push rod. Through the gear coupled mechanism, the axle center of said counter and the wheel axle form a joint relationship having the same rotational cycles. A front yoke is attached to the wheel axle in the end of said push rod, and a set of magnetic element is disposed between the wheel axle and the interior side of the front yoke. This prevents the wheel from rotating by itself that affects actual measured distance.

This invention relates to a mobile measurement system of three-dimensional structure comprises a measuring equipment 5 to measure three-dimensional structure of an object for measurement and a barrow 4 for moving measurement which the equipment 5 is mounted. The measuring equipment 5 has a digital camera 5a, a slit floodlight 5b, and a three-dimensional structure calculating device that calculates and outputs three-dimensional structure of the object by using a light plane range-finding method from the each position and direction of the floodlight and the camera and the picture that is taken by the camera. The barrow has an measurement position and direction calculating device that calculate the each position of the floodlight and the camera, the direction of the floodlight, the direction of the camera at the measurement by the equipment in accordance with an information of self-contained navigation from an acceleration sensor 9 and a rotation angle sensor 10 that detects an acceleration and a rotation angle of the barrow, respectively, and an information of moving distance from the wheel revolution sensor 8 and transmit the result of the calculation to the three-dimensional structure calculating device 7.

An apparatus for detecting the probable existence, location, and type of defects in a workpiece is described. The apparatus includes a sensor subsystem, an optimizer, a control subsystem, and a computer system having a processor and computer readable memory. Sensor subsystem senses a first section of the workpiece and produces signals corresponding to a physical characteristic of the workpiece. The computer system is configured to generate a workpiece model based on the signals produced by the sensor subsystem. In an alternate embodiment, a defect assembler can be provided to merge signals from a plurality of sensor subsystems. The defect assembler can also be configured to generate the workpiece data model. The optimizer is configured to generate workpiece segmentation recommendations based on the workpiece data model. The processor is configured with a first producer thread program which, in response to the receipt of a first set of signals by the computer system, receives a data subscription request from a subsystem which uses data and transmits the signals from the computer readable memory to the generator of the data subscription request. The processor is further configured to generate a second producer thread in response to storage of a second set of signals in the computer readable memory. The second producer thread is configured to receive one of the data subscription requests and selectively send the second set of signals to the generator of the data subscription request. A tracking device for tracking selective kinematics of a workpiece moving through a plant is also disclosed. The tracking device includes an encoder wheel configured to tangentially contact a workpiece and rotate at an angular velocity coincident with the linear velocity of the workpiece. The tracking apparatus further includes a drive mechanism for driving the encoder wheel at a first angular velocity approaching the angular velocity of the encoder wheel which is coincident with the linear velocity of the workpiece. The tracking device also includes a signal generator configured to interact with the encoder wheel and generate a signal in response to the angular velocity of the encoder wheel. The tracking apparatus can be incorporated into the apparatus for detecting defects within a workpiece by providing the signal from the signal generator to the control subsystem.

An electronic measuring device is disclosed which includes a pair of wheels connected to an axle that passes through a drive gear. The drive gear is enmeshed to a second gear which, in turn, is coaxially connected to an encoder disk. The encoder disk has spaced-apart fins around its outer periphery. As the wheels turn and the encoder disk rotates, the fins and openings between the fins pass between an emitter and a receiver. The emitter and receiver are linked to a controller which calculates the distance traversed by the wheels based upon the number of fins that pass between the emitter and receiver, or with an active counting system (ACS). The controller also includes functions to establish start and stop points for a measurement and an easy means for dividing a measured distance into equal parts or segments and a means for marking the boundary points that define the segments when the measuring device is rolled back across the measured distance. The device can be used on both planar and non-planar surfaces.

This invention relates to a barrow for moving observation which observation equipment 5 is mounted and is driven by one wheel that contacts with a travel surface comprising an acceleration sensor 9 which detects the rotation angles around the mutually orthogonal x, y and z axes, a rotation angle sensor 10 which detects the rotation angles around the mutually orthogonal x, y and z axes, a wheel revolution sensor 8 which detects the revolution of the wheel, a computer 7 that calculate a position and a zenithal angle and a azimuthal angle of the direction of the observation of said equipment 5 in accordance with an information of self-contained navigation from said acceleration sensor 9 and said rotation angle sensor 10 and an information of moving distance from said wheel revolution sensor 8 at least in the observation by said equipment 5.
