摘要:
A lighting system including modules containing LEDs or other electroluminescent devices and loosely constrained magnetic structures at least partially contained within cavities in the module substrate that are connected to fixtures under magnetic force. The loosely constrained magnetic structures accommodate mechanical variations in the system and provide a method to connect modules mechanically, electrically and thermally to different fixtures or positions in fixtures without tools. The relatively short distance separating magnetic structures provides high connection forces with the use of relatively small magnets. Magnets and electrical contacts are not located directly between the LED subassembly and the fixture, which provides higher thermal conductivity pathways to remove heat from the LEDs. Biasing members may be used to increase thermal contact. Magnetic structures may, but are not required, to conduct electricity. Fixtures that attach to modules include rails, sockets, heat sinks and two-dimensional structures with recessed electrodes for improved electrical safety.

A magnetic tile construction set is disclosed that may be used to construct extended 3-dimensional structures. In one embodiment, plastic magnets are attached to multiple edges of a lightweight core. The magnets have a width and length comparable to the thickness of the core and a length that is an order of magnitude longer than the thickness of the core. Tiles may be attached to one another at the tile edges through magnetic forces that do not vary by more than a factor of two over the range of angles from 45 degrees to 180 degrees.

Disclosed are interposer electrical connector embodiments including magnetic components used to facilitate interconnection of peripheral devices to standard input/output, or “I/O”, connectors (such as USB connectors) of devices such as mobile communications products (e.g. smart phones, tablets, and personal computers). The interposer connector embodiments disclosed include those in which a plurality of discrete permanent magnets are arranged with magnetic poles aligned in the same orientation perpendicular to and on one side of the electrical interface. Other embodiments include a plurality of bar permanent magnets located on opposite sides of the interface with all poles of the same type directed at the interface, but each one opposing a ferromagnetic element. These arrangements provide self-aligning capabilities useful for electrical connections that have restrictions on visibility or connection approach geometries. Other embodiments have a single magnet per mated connector pair and magnetic pole pieces and/or actuators to concentrate magnetic flux providing the magnetic attractive force for a plurality of electrical connections.

In accordance with the present invention, there are provided apparatus and methods useful for efficiently subjecting photosensitive materials to a relatively low energy pre-exposure using the electromagnetic energy during the non-imaging portion of the exposure process (i.e., a backscan beam exposure) prior to subjecting such materials to the main imaging exposure (i.e., an imagewise exposure). In a further aspect of the present invention, there are provided combinations and improvements useful for the enhanced imagewise exposure of photosensitive materials. In additional aspects of the present invention, there are provided methods of enhancing the imagewise exposure of photosensitive materials, imagewise exposed photosensitive material made according to such methods, methods for enhancing sensitivity of a photosensitive material for imagewise exposure, and photosensitive materials having enhanced sensitivity for imagewise exposure made according to these methods.

Suspended and planar electrode systems and methods are disclosed for applications such as lighting. Some embodiments incorporate removable twist-on elements providing uniform spacing between cable rod or strip electrodes extending through space. Multiple electrodes may be attached simultaneously. Twist-on elements may contain light emitting elements electrically attached to parallel electrodes. Embodiments may include mounting features for fixing electrodes above a mounting surface. Some embodiments include electrically insulated electrodes and modules with insulation displacement contact elements and environmental sealing. Some embodiments include polymeric insulation on both the module and electrodes providing environmental sealing when modules are disconnected from electrodes. Electrodes in sealed systems may be suspended with spacers or built into planar arrays in walls, ceiling or furniture. Some embodiments include folded electrode gyrating tracks having mounting positions providing different axial and radial pointing directions. Modules may be attached to electrodes by mechanical or magnetic forces.

The photolithography tool of the present invention in its simplest embodiment includes an afocal lens system and a three-dimensional master or mask. The three-dimensional mask is located within the object space of the afocal lens system and is imaged onto a three-dimensional circuit carrier or substrate located within the imaging space of the afocal lens system. By using an afocal lens, with which persons skilled in instrumental optics are familiar, a system can be designed for which the object space is identical to the imaging space for unity magnification. As a result, a mask can be used in which the surface contour and pattern to be imaged is identical to the desired substrate surface and pattern, thereby simplifying mask design.

Embodiments of electrode systems having non-uniform spacing between electrodes along the axial direction for track lighting and other linear systems are disclosed. These systems may be used to provide directional flexibility for removable lighting fixtures with an asymmetric light distribution by providing a range of module position and angular mounting options. Some embodiments include electrodes which overlap continuously or at a series of discrete crossover overlap nodes to provide lateral support without external spacers. Electrode segments may be electrically and mechanically attached at overlap nodes to create extended two- and three-dimensional structures with localized planar areas. Embodiments with preferential bending regions provide additional directional capability. Embodiments of electrode systems integrated into planar surfaces or combined into extended suspended arrays are disclosed Modules with magnetic connectors having complete magnetic flux paths for use with the electrode systems are also disclosed.

摘要:
A flexible magnetic interconnect is disclosed. In one embodiment, an apparatus includes a module having a recess therein. A magnetic structure is moveable within the recess and a flexible circuit cooperates with the module to retain the magnetic structure within the recess. Movement of the magnetic structure is caused by magnetic attraction between the magnetic structure and an external magnetic structure. The flexible circuit includes a compliant contact, which changes shape by movement of the magnetic structure.
