Abstract: A method and apparatus for analysis of brakes in automotive vehicles, and related aspects of engine performance and like applications, senses heat energy which is generated internally of an article to be analysed. Spot-type infra-red thermometers are employed to sense localised temperature elevation produced by brake application from a remote location using visual positioning guides to enable the spot zones sensed to be accurately located on, for example, wheel nuts/studs, which provide a thermal transfer route from the brake drums or discs. Analysis of the thermal data from the sensors includes a peak detect-and-hold function to avoid the need for maintenance of accurate alignment of the sensors. Comparison of the thermal data enables detection of braking imbalance.

Abstract: A current shunt for converting a current to a voltage. The current shunt of the invention is made from a conductive material such as a high performance resistance alloy in sheet form which is sheared, punched, and bent to produce a highly stable current shunt with respect to time and temperature. Contact pins of current and potential connections are welded to the material using a fusion welding process, and techniques are also provided for isolating the potential contacts from the current contacts so as to improve stability. Trimming slits of the type used for thin film or foil resistors are also extended to bulk materials in accordance with the invention such that highly accurate resistances may be obtained. An integral heat sink and strain relief mechanism is also provided so as to minimize the adverse effects of temperature on the resistance of the material. The resulting current shunt has an extremely stable resistance value with respect to time and temperature at a minimal cost.

Abstract: A robotic transport and assembly system includes a worktable upon which are supported a printed circuit board conveyor, a controllably displaceable circuit component feed mechanism and a robotic manipulator, mounted on the worktable and having a multi(four)-axis end effector, for controllably seizing an electronic circuit component from the component feed mechanism and placing the seized component on the printed circuit board for surface mounted attachment. The controllably displaceable circuit component feed mechanism, which includes a component feed device and an associated feeder device positioning table, is mounted on the worktable at a position adjacent to the position whereat a printed circuit board is supported for the pick and placement operation of the robotic manipulator. The component feed device controllably supplies a plurality of the components to be seized by the end effector and placed on said workpiece by the robotic manipulator.
