  • Patent number: 11950713
    Abstract: Systems disclosed herein are directed to a display stand unit for a retail environment. The display stand unit includes a base having an interior and a display stand. The display stand includes a stem that connects to and extends upwardly from the base and a receiving surface that is suspended above and spaced away from the base by the stem. The receiving surface is configured to releasably hold an electronic device above and spaced away from the base. The display stand unit further includes a security cable that extends out from the base. The security cable is configured to attach to the electronic device to movably secure the electronic device to the base. The display stand unit further includes a retractor disposed within the interior of the base and connected to the security cable. The retractor automatically retracts the security cable.

  • Patent number: 10720789
    Abstract: A wireless charging system including a transmitter and a receiver. The transmitter is formed of a coil of wire that includes a first loop portion, a second loop portion, and a crossing portion. The crossing portion electrically couples the first loop portion and the second loop portion such that when current is generated in the coil, electrical current flows through the first loop portion in a different rotational direction than in the second loop portion. The receiver is formed of a ferromagnetic core and multiple (e.g., three) coils disposed about the ferromagnetic core. Each coil may be disposed about a different axis of the core such that current may be induced in at least one of the coils by a magnetic field in any direction.

  • Patent number: 10333333
    Abstract: A wireless charging table comprising a table top having an upper surface upon which one or more electronic devices can be placed, a wireless charging transmitter positioned under the upper surface of the table top, the wireless charging transmitter comprising a plurality of transmitter coils that define a charging region at the upper surface of the table top, and a power distribution system operatively coupled to the wireless charging transmitter, the power distribution system configured to receive power from an alternating current (AC) power source and distribute power to the wireless charging transmitter. The plurality of transmitter coils include at least a first transmitter coil comprising: a first loop portion; a second loop portion; and a crossing portion comprising overlapping conductive paths that electrically couple the first loop portion.

  • Patent number: 10282339
    Abstract: Systems for presenting electrically supported devices and methods for assembling the same are provided. A platform assembly may be equipped with one or more features for enabling a support module assembly to be easily removed from a bottom table surface of a table and replaced with another support module subassembly (e.g., to physically upgrade the support module assembly) while maintaining the position of a user device and/or cable assembly with respect to the table).
