A reading lamp (100) includes a lamp holder (20), a lampshade (40), a bracket (30) connecting the lamp holder with the lampshade, and a white light illuminator (50) received in the lampshade. The white light illuminator includes a light mixer (52), and at least a group of solid-state, light emitting elements (544) arranged to at least one side of the light mixer. The at least a group of solid-state, light emitting elements includes three kinds of solid-state, light emitting elements which respectively emit red, green and blue lights. The light mixer reflects, refracts and mixes the red, green and blue lights to obtain white light which directly radiates and spreads from a light emitting surface (521) of the light mixer.

The present invention relates to personal care liquid cleansing compositions comprising bacterially produced microfibrous cellulose (MFC) suspending polymers which have not previously been used in personal care compositions.
摘要:
A personal care composition is provided which includes from 0.1 to 30% of a dihydroxypropyltri(C1-C3 alkyl) ammonium salt by weight of the composition; from 0.0001 to 0.005% of a tri(C1-C3 alkyl)amine or protonated form thereof by weight of the ammonium salt; from 0.002 to 15% of an aluminum salt by weight of the composition; and a cosmetically acceptable carrier wherein the composition has a pH ranging from 5.5 to 6.9. Unpleasant amine odor from trialkyl amines which arise from the dihydroxypropyltri(C1-C3 alkyl) ammonium salts is suppressed by the aluminum salt and by careful control of pH conditions.
摘要:
A securing device (30) is used for securing a heat sink (10) to a printed circuit board (40) with a heat-generating electronic component (41) mounted thereon. The securing device includes a V-shaped elongated main body (31), a first locking leg (34), a second locking leg (332) and a resilient member (32). The first locking leg and second locking leg are connected to two opposite ends of the main body respectively for engaging with a retention frame (20) on the printed circuit board. The resilient member includes a planar-shaped supporting plate (321) engaging with a bottom portion of the main body and at least one resilient foot (322) extending downwardly from the supporting plate. The resilient foot deforms to exert a resilient force on the heat sink when the heat sink is assembled to the electronic component by the securing device.

A method comprising the steps of providing a slicer for slicing real values of an equalizer output; and cross correlating an equalizer input with an output of the slicer is provided.
摘要:
An LED lamp (100) includes a lamp enclosure (10), a heat sink (51) and two LED modules (30). The lamp enclosure has a recess (15) and an opening (156). The heat sink is received in the recess of the lamp enclosure. The LED modules are attached to a bottom of the heat sink and oriented downwardly and outwardly towards an internal surface (1110) of the lamp enclosure. Light emitted by the LED module is firstly directed to the internal surface and other internal surfaces (130, 1130), and then reflected from the internal surfaces to an outside of the LED lamp through the opening.

摘要:
A tensioning pin system (10) is provided for use in shutter-louver assemblies (12). The major component of the system (10) is a tensioning pin (50) in two mating parts; a pin member (52) and a ferrule member (54) which fit together and rotate with respect to one another. The pin member (52) is lodged within a louver slat (16) while the ferrule member (54) is firmly embedded into the shutter frame (14). The tensioning pin (50) maintains rotational tension for placement of the louver slat (16) and lateral separation between the louver slat (16) and the frame (14). A preferred interface between the pin member (52) and the ferrule member (54) includes an annular protrusion (80) mating with a catch channel (74) while alternate tension interfaces incorporate varying gradients on one of the members with a bead ring on the other member.
