  • Patent number: 10220254
    Abstract: Methods and apparatuses for athletic performance monitoring with body synchronization analysis are disclosed. In one example, a first sensor output associated with a movement of an user foot and a second sensor output associated with a movement of an user arm are received, the user arm on a body side opposite the user foot. The first sensor output and the second sensor output are analyzed to identify a degree of synchronization between the movement of a user foot and the movement of a user arm.

  • Patent number: 4947215
    Abstract: An apparatus which transfers a liquid image from an image support surface to a sheet. A deformable cylindrical member made from a flexible, dielectric material presses the sheet against the image support surface. As the cylindrical member presses the sheet against the image support surface, it deforms to define a transfer area. A conductive roll, disposed interiorly of the cylindrical member in the transfer area, tacks the liquid image to the image support surface. A corona generating device, positioned adjacent the conductive roll interiorly of the cylindrical member, transfers the liquid image from the image support surface to the sheet.

  • Patent number: 4851317
    Abstract: Apparatus for developing a latent electrostatic image on the image bearing surface of an imaging member using a liquid toner is characterized by a toning station having a toning member therein. The toning member has a conductive and a nonconductive element thereon. The nonconductive element is disposed upstream of the conductive element in the direction of movement along the path of travel of the image bearing surface through the toning station. The conductive element is connected to a bias voltage so that the image is toned first in the absence of a bias followed by toning in the presence of a bias voltage. Laminar toner flow is maintained in the direction of movement of the image bearing surface during the contact of the surface with the toner.
