A tire changer with a controller includes a with a mount assembly adapted for contacting a wheel assembly to mount the wheel to a rotating spindle. The tire changer controller is configured to regulate the operation of a motor, and which is operatively connected to the rotating spindle to rotate the wheel assembly. A sensor coupled to the controller provides a data representative of the rotational position of the wheel assembly about a rotational axis. The controller is further configured to engage a load roller with the wheel assembly to apply a radial force to a tire mounted on a rim of the wheel assembly during rotation of the wheel, and to regulate the operation of a tire handling means and mount assembly, enabling identification, optional marking, and adjustment of the tire angular mounting position relative to the wheel rim.

A data collection and processing system includes a hand-held tool for measuring the spacing between two locations on a test object such as automobile body panels. The tool generates and transmits a measurement signal to a remote data processing unit in response to a single operator input. The data processing unit compares the measurement signal with a predetermined range of values and classifies the measurement signal as either in-range data (i.e., when the measurement falls within the range of values) or out-of-range data (i.e., when the measurement falls outside of said range of values). If the measurement signal reflects an in-range measurement, the database is updated with the measurement signal as being in/out of specification. If the measurement signal reflects an out-of-range measurement, the signal is classified as a functional flag, advancing the system to a next measurement group or confirming vehicle status (e.g., measurement complete or hold for re-work).

An inspection jig for a display device includes a jig body, the jig body includes a limit groove configured to limit the position of the display device to be inspected, and the jig body is provided with a soldering point testing portion, the soldering potin testing portion is provided with a plurality of testing terminal pairs; each of the testing terminal pairs comprises two testing terminals; in every two adjacent testing terminal pairs, one testing terminal of one testing terminal pair and one testing terminal of the other testing terminal pair are serially connected with an indicator lamp therebetween; along a serial connection direction of the testing terminals, a testing terminal located at two ends are electrically connected with a positive pole and a negative pole of a power source.

A method for determining elastomer types as pipe filler for pressure bending of a pipe, comprising: selecting a set of elastomer types; obtaining sample pieces from the elastomer types; applying strain test on the sample pieces; determining properties of the sample pieces; calculating strain energy and error function for each sample piece based on an energy model; calculating elastic modulus for each sample piece; selecting elastomer types from the set of elastomer types; analyzing results from the calculation of strain energy, error function and the elastic modulus for the selected elastomer types; simulating the pressure bending process of the pipe, using pipe filler made from the selected elastomer types; and when simulation results indicate an acceptable pressure bent pipe due to the simulated pressure bending, selecting the one or more elastomer types associated with the acceptable pressure bent pipe for the pipe filler.

A pipeline inspection apparatus includes a main body. A sealing structure attached to the main body seals against an internal surface of the pipeline. An imaging module includes a camera and a light source. The light source is arranged to emit light in a direction towards the internal surface of the pipeline. The camera is arranged such that, in use, the camera captures image data of the internal surface of the pipeline. Control circuitry includes a power supply and memory for storing data captured by said camera, wherein the sealing structure forms a seal against the internal surface of the pipeline such that, in use, a fluid flowing along the pipeline applies a driving force to the pipeline inspection apparatus to propel the apparatus along the pipeline.
