Abstract: Novel arrangements of elements (e.g., individual emitters or stacks thereof) produce three-dimensional full-color light-emitting displays. In an embodiment, planar arrays of regularly-spaced elements and electrical conductors can be configured together by staggering the layers' respective lateral positioning and controlling the pitch between layers. Various advantages may include smooth flow of voxels and boundaries and/or enhanced three-dimensional appearance versus conventional direct stacks.

Abstract: A volumetric three-dimensional light-emitting display, comprising an array of elements arranged, as defined by the relative positions of the elements' centerpoints, in a close-packed relationship; and an array of conductors in electrical contact with the array of elements. The array of elements comprises voxels consisting of four elements and capable of producing full-color.

Abstract: A volumetric three-dimensional light-emitting display, comprising an array of emitters arranged, as defined by the relative positions of the emitters' centerpoints, in a close-packed relationship; and an array of conductors in electrical contact with the array of emitters. The array of emitters may for example comprise conventional RGB stacks or similar full-color assemblages or four different-colored emitters.

Abstract: A personal audio player system comprising a first earpiece having a body, an anchor attached to the body and shaped to fit a human ear, an onboard audio speaker, onboard persistent memory capable of storing multiple songs, an onboard power source, onboard interface controls, and onboard electronic circuitry comprising an interface module and an audio playback module. In an optional embodiment, the system may further comprise a second earpiece that has a body, an anchor attached to the body, and an onboard audio speaker. In one of a number of variations of that optional embodiment, for example, the second earpiece may also include its own onboard persistent memory from which it can play the same content as, and in synchronicity with, the first earpiece, further optionally aided by the transmission of synchronization signals from the first earpiece.

Abstract: An adjustable linear locking assembly, such as may be used in a mounting device or other suitable devices, which assembly allows automatic, substantially continuous adjustment to the linear position of a locking element such as an interface. The assembly may also provide two-way adjustability.

Abstract: A device that provides adjustable hanging of an item, such as a picture frame, on a vertical support such as a wall. The hanger may provide for automatic, in situ, and/or substantially continuous vertical adjustment, and/or horizontal adjustment. The adjustable hanger may comprise a first portion affixed to the vertical support, and a second portion that engages with the first portion and fixedly attaches to or is incorporated in the reverse side of the item, with one or both of the aforementioned portions being formed to allow automatic, in situ, continuous vertical adjustment and selective locking with respect to the other portion through a clamp, bias, or similar means; one or both these portions may also be formed to allow horizontal adjustment and repositioning with respect to the other portion. Also disclosed is a device for horizontally extending the available range of mounting positions for items that need to be supported by a stud.

Abstract: A device that provides automatic, in situ, substantially continuously adjustable mounting of an item on a vertically oriented support, comprising a first portion affixed to the vertical support, and a second portion that fixedly attaches to or is incorporated in the reverse side of the item. One or both of the two portions is formed to allow automatic, in situ, continuous vertical adjustment and repositioning with respect to the other portion, and one or both portions may also be formed to allow horizontal adjustment and repositioning with respect to the other portion. Also, a device for horizontally extending the available range of mounting positions for items that need to be supported by a stud.
