摘要:
A solid state lighting apparatus includes a plurality of light emitting diodes (LEDs) including at least a first LED and a second LED. Chromaticities of the first and second LEDs are selected so that a combined light generated by a mixture of light from the pair of LEDs has about a target chromaticity. The first LED may include a first LED chip that emits light in the blue portion of the visible spectrum and a phosphor that emits red light in response to blue light emitted by the first LED chip. The second LED emits light having a color point that is above the planckian locus of a 1931 CIE Chromaticity diagram, and in particular may have a yellow green, greenish yellow or green hue.

The disclosure relates to multiple quantum well (MQW) structures for intrinsic regions of monolithic photovoltaic junctions within solar cells which are substantially lattice matched to GaAs or Ge. The disclosed MQW structures incorporate quantum wells formed of quaternary InGaAsP, between barriers of InGaP.

An animal house (1) comprises a base (2) and a cover (3) affording a roof and side walls for the house (1) and engaging with the base (2), to which it is attached by a hinge. Releasable fastening means (5) secure the cover (3) to the base (2) such that, when released, the cover (3) may be removed to afford access to the base (2) from above. An end wall (4, 12) of the houselengages one side of the base (2). A panel (12) of the end wall is removable and exchangeable with other panels of different configurations, to suit different animals and/or occasions. Modular inserts (11) fit into the base (2) and are exchangeable with other inserts of different configurations, to suit different animals and/or occasions.
摘要:
An EMI filtered terminal assembly including at least one conductive terminal pin, a feedthrough capacitor, and a counter-bore associated with a passageway through the capacitor is described. Preferably, the feedthrough capacitor having counter-drilled or counter-bored holes on its top side is first bonded to a hermetic insulator. The counter-drilled or counter-bore holes in the capacitor provide greater volume for the electro-mechanical attachment between the capacitor and the terminal pin or lead wire, permitting robotic dispensing of, for example, thermal-setting conductive adhesive.

A universal smart remote control includes intelligence software and algorithms that have been programmed into the remote control's microprocessor memory, and a large display which is used to prompt the user to take certain actions. The remote control provides guidance to the user in setting up and operating the various components of his or her entertainment system, and asks the user non-technical questions that are understandable to the user.
