  • Publication number: 20240112494
    Abstract: An elongated biometric device provides a slim solution for capturing biometric data, and may be placed on a portion of an electronic device having limited space, such as a side of the electronic device. The elongated biometric device may include a force sensor, which may be positioned within a housing of the electronic device and actuated through posts extending from the elongated biometric device through the housing to transfer an applied force to the force sensor.

  • Patent number: 9694573
    Abstract: A material deposition technique is disclosed for transferring material to a substrate. The material may be a foil on a carrier and the substrate may be printable paper. A computer-controlled, material application subsystem is provided having a material roller assembly including one or more material pressing rollers. The entire assembly is configured for controlled rotation such that the material pressing rollers alternately engage and disengage an impression cylinder. In a first rotatable position, the material roller assembly is rotated so that one of the material deposition rollers over which the material carrier is fed engages the impression cylinder and deposits the material onto the substrate as it passes beneath the roller. In a second rotatable position, the material roller assembly is rotated so as to disengage the material roller from the impression cylinder thereby precluding deposition of material onto the substrate as it passes beneath the roller.

  • Patent number: 6147580
    Abstract: An improved low voltage winding for dry insulated transformer has its windings resin encapsulated. The winding is constructed with flexible sheet conductors wound coincident with an insulating sheet material. Insulating spacers provide a means to form air channels in the windings during the coil forming process. A sealant is applied to openings at the lower ends and along vertical seams of the coil prior to the resin impregnation and encapsulation process. This will prevent drainage of the resin during a curing cycle. The result is a coil that exhibits high short circuit protection due to the tightly bond sheet conductors which will prevent movement of the conductors during short circuit conditions and also increases the radial compressive strength of the coil.
