The invention provides a multi-use light fixture that includes a light engine, a rugged housing, and an external power supply removeably embedded within an optional external enclosure. The light fixture includes several novel heat management features designed to reduce the risk of failure and thereby increase the reliability of the light fixture. The light engine includes groups of light modules, each having a light emitting diode (LED) and a zener diode. The housing includes an internal gap defined between the a circuit board and the housing. The housing also includes an arrangement of external fins and vents that dissipate heat generated by the light engine. The lens cover includes a plurality of inlets to supply ambient air into the fixture. During operation, heat is generated by the light modules, namely the LEDs, and then is transferred along a first flow path through a main body portion of the housing and the fins for dissipation to ambient and a second air flow path whereby ambient air flows through the light engine to increase the performance and efficiency of the light engine.

A holding device for temporarily attaching a facial tissue box or similar container to a supporting structure such as glove box door, sun visor, window, bed railing or headboard, or similar. The device is removably attachable to both the box and the supporting structure. Two laterally projecting arms grip the box while a clip attaches to the structure. The arms may comprise hooks, points or other features designed to enhance their grip on a paperboard, or similar, box. These features may optionally penetrate, crimp, or depress the side of the container. If desired, one or both of the arms may be adjustable to accommodate a range of box widths and / or depths.

A method is provided, the method comprising controlling an implantable medical device using a controller using a pre-emptive real-time operating system (RTOS) having a scheduling mechanism utilizing a priority inheritance protocol, the controller having a firmware architecture allowing at least one of modular feature design, modular feature implementation, extensible feature design and extensible feature implementation. The device also comprises analyzing the pre-emptive real-time operating system (RTOS) using rate monotonic analysis, providing an interface with downloadable software for the implantable medical device and backing up at least some of the downloadable software using a non-volatile memory device, protecting the at least some of the downloadable software from a reset of the implantable medical device.

A two-optic accommodative lens system is disclosed. Two coupled lenses are located within the capsular bag to extend depth of focus and / or restore accommodation following extraction of a natural lens. The first lens comprises a spring-like structure attaching an optic to a ring-like support structure. The optic can be a monofocal or multifocal optical element having a positive or negative power. The first lens further comprises features designed to couple the ring-like structure to a second lens. The first lens can be located anteriorly within the capsular bag. The second lens is located posteriorly to the first lens within the capsular bag and can have an opposite or supplementary power to that of the first lens. The second lens can also be a monofocal or multifocal lens and comprises a plurality of haptics which can be used to size the lens system over a range of capsular bag sizes. The second lens further comprises features for coupling the second lens to the ring-like structure of the first lens. The haptics of the second lens are relatively firm, yet still flexible and can be configured to interlock with features of the ring-like structure.

A backlight is provided for illuminating an at least partially transmissive display. The backlight includes a light source. A light guide receives the light from an edge surface and guides the light by total internal reflection. The light is extracted from the lightguide using sub-wavelength extraction features designed on the basis of two interleaved grating structures. The emitted light, using this arrangement has a high level of polarization.

Electrical enclosures are provided that include arc resistant features designed to add structural strength for arc containment, to inhibit arc propagation, and / or to direct the release of pressure within and / or from the enclosure in order to provide arc resistant electrical enclosures. In general, the arc resistant features may be designed to provide enclosures where in the event of an arc fault, the doors and covers remain closed, parts are not ejected from the enclosure, holes are not produced in the enclosure, indicators located in close proximity to the enclosure do not ignite, and / or grounding connections remain effective. Further, the foregoing features may be designed to provide electrical enclosures that comply with industry guides and standards for arc resistant ratings.

A current mortgage price indicator futures contract (“Mortgage Futures Contract”) that can be traded on a futures exchange. The contracts add value over existing hedging and speculating alternatives by meeting the needs of a wide range of mortgage and mortgage-backed securities (MBS) market participants such as portfolio managers, dealers, hedgers, originators, speculators and arbitrageurs. The Mortgage Futures Contract is based upon conventional MBS and has a relatively current coupon composition, thereby resulting in risk properties that appeal to market participants more so than prior contracts based on non-conventional MBS that were not correlated to current MBS production. The Mortgage Futures Contract has a cash settlement feature designed to eliminate complicated and largely uneconomic physical delivery of the underlying security. An options contract corresponding to the Mortgage Futures Contract and that can be traded on a futures exchange.

This water board sport system comprises a water skimming board device attached to one end of a resilient buoyant tether, the other end of which is secured to an anchor to provide a rider of the board with motive force from flowing water. The tether comprises a braid of mandrel-dipped latex tubing for extreme elongation. A rider may maneuver the board to stretch the tether, charging it as a cocked spring. Release of the force stored in the stretched tether propels the board and its rider upstream at speeds much greater than that of the water flow alone allowing the rider to fly at or above the water surface. Control features designed into the board enhance its maneuverability. Safety features are part of the system to ensure that the user may safely enjoy using it.
