  • Patent number: 11984564
    Abstract: Embodiments described herein relate to electrochemical cells with dendrite prevention mechanisms. In some aspects, an electrochemical cell can include an anode disposed on an anode current collector, a cathode disposed on a cathode current collector, the cathode having a first thickness at a proximal end of the cathode and a second thickness at a distal end of the cathode, the second thickness greater than the first thickness, a first separator disposed on the anode, a second separator disposed on the cathode, an interlayer disposed between the first separator and the second separator, the interlayer including electroactive material and having a proximal end and a distal end, and a power source electrically connected to the proximal end of the cathode and the proximal end of the interlayer, the power source configured to maintain a voltage difference between the cathode and the interlayer below a threshold value.

  • Patent number: 7621415
    Abstract: A storage is provided for an interactive display system that both provides a graphic display and responds to objects disposed proximate to or in contact with a display surface. Due to a limited available volume within a housing of the interactive display system, the storage is provided either external to the housing, or within a peripheral portion of the housing so as not to interfere with the operation of the interactive display system. In one embodiment, a sheet of flexible material is coupled to an exterior surface of the housing. Elastomeric edges of the sheet are pulled away from the housing to provide access to a volume disposed between the sheet and the external surface of the housing. In another embodiment, pockets are formed within a sheet hung from a backing, adjacent to the external surface. Yet another embodiment includes a drawer within a peripheral portion of the display.

  • Publication number: 20070247755
    Abstract: A slider device includes a tab capable of movement in a first linear direction and a second linear direction. A first spring and second spring are each disposed adjacent the tab. The first and second springs are capable of biasing the tab into a biased position. The first spring is further capable of providing mechanical resistance to the movement of the tab in the first linear direction and the second spring is capable of providing mechanical resistance to the movement of the tab in the second linear direction. An electric circuit is coupled with the tab and operative to generate a first signal comprising information corresponding to an distance of movement of the tab in the first linear direction and a second signal comprising additional information related to a distance of movement of the tab in the second linear direction.
