  • Patent number: 10044203
    Abstract: A tablet storage device includes a module on a cart frame that includes a wheeled base. A cart module defines a selectively accessible interior space having multiple storage slots within the interior space for holding tablets. In some cases a tablet storage device holds multiple tablets using two or more modules in a stacked arrangement on a wheeled base. Each module can hold a portion of the multiple tablets within storage slots within an interior space inside the module. The storage slots may have connectors for connecting to tablets, and the cart frame can have a network connection system that is adapted to provide a network connection for each tablet that is connected to one of the connectors. The cart frame may also have a power supply system for charging each tablet that is connected to one of the connectors.

  • Patent number: 9030828
    Abstract: A tablet storage device includes a frame having a plurality of slots, at least one of which is adapted to hold a tablet. A docking station can be disposed in at least one slot. In some cases the docking station is configured to align a tablet as the tablet is positioned in the slot such that a corresponding port in the tablet aligns with, and connects to, a connector. The frame also has a surface to attach the device to a vertical surface and can have a door that can be moved from an open to a closed position and adapted to retain at least one tablet held within at least one slot when the door is closed. A power supply system and/or a network connection system can be provided with the tablet storage device.

  • Patent number: 8935011
    Abstract: A load management system provides an interface between a power input and several switched power outputs and un-switched power outputs. A controller groups the switched power outputs into one or more load groups based on a switched current limit determined for the system and the measured currents of the electrical loads. The load groups are defined so that the sum of electrical load currents in each load group does not exceed the switched current limit. The controller also activates one or more switches to apply electrical power to the load groups according to a power sequence. A method for distributing electrical power to electrical loads using load groups is also provided.

  • Patent number: 8397997
    Abstract: A removable spindle for use in a thermal transfer printer houses dual RFID reader antennas that are used to read an RFID tag attached to the core of the print media. The information provided by the RFID tag enables the printer to self-calibrate based on the type of media loaded. The antenna design eliminates “null” areas at which the tag cannot be read, and enables the tag to be read around and across the entire length of the printer spindle. The design also allows the media holder to be easily removed from the printer.

  • Patent number: 6860658
    Abstract: Disclosed herein is a ribbon wiper that is disposed within a ribbon cartridge. The ribbon cartridge can contain a ribbon and be employed by a thermal printer. The ribbon wiper is capable of removing debris and other contaminants from a printhead surface of the ribbon. The printhead surface of the ribbon is that surface that faces the printhead, and opposes the ink surface of the ribbon, during printing. Debris disposed on the printhead surface of the ribbon can hinder or obstruct thermal contact between one or more thermal elements on the thermal printhead. In such cases, the thermal element can lack the ability to properly produce a dot on a media as instructed by the thermal printer. Further, debris disposed on the printhead surface of the ribbon can accumulate on the printhead proximate thermal elements and prevent generation of multiple or consecutive dots.
