  • MULTIPOINT SERIES SENSOR IN ELECTRIC HEATING ELEMENTS
    Publication number: 20220026285
    Abstract: A temperature sensing system includes a plurality of resistive segments connected in electrical series. Each resistive segment defines a material different from a material of an adjacent resistive segment, and the plurality of resistive segments are joined at sensing junctions to define a plurality of sensing junctions along a length of the resistive segments. A temperature deviation is calculated from the plurality of sensing junctions based on electric potential at each of the sensing junctions.

  • Quilling tool
    Patent number: 9925735
    Abstract: A quilling tool includes a housing, a motor, a spindle, and a platform. The motor is positioned inside the housing and coupled to a power source. The spindle is coupled to the motor and extends from the housing. The motor is operable to rotate the spindle when powered by the power source. The spindle has a portion for receiving a separate strip of paper. The platform is positioned adjacent the spindle and the housing. The platform is removable from the body in order to remove a wound strip of paper. A method for quilling strips of material is also included.

  • Selective wave solder system
    Patent number: 7213738
    Abstract: The present invention relates to a selective wave solder machine. In particular, it relates to a system for calibrating and adjusting process points to account for variations in machines and circuit boards. Vision systems are used to locate fiducials on the processing modules and the circuit boards. Differences between stored locations for fiducials relating to the circuit board and the processing modules are used to adjust the positions of stored process points to achieve improved performance.
