Assignee:

HTI Technology & Industries, Corp - La Verne CA

International Classification:

E05C 3/06

US Classification:

292201, 292216

Abstract:

A power latch assembly which includes a supporting frame adapted for mounting on a main housing, wherein the supporting frame has a locking slot and defines first and second slider ends thereof; a motor assembly including a power motor supported by the supporting base and adapted for being powered by the main housing, and a driving arm driven by the power motor in a linear movable manner; and a locking latch, defining a first guiding edge and a second guiding edge, having an inner coupling end coupling with the driving arm and an opposed latching end extended outwardly through the locking slot, wherein the driving arm drives the locking latch between a locking position and an unlocked position.

Abstract:

A mechanical latch assembly includes a supporting frame, a locking latch, an actuation arrangement and a safety lock arrangement. The locking latch is slidably mounted on the supporting frame in longitudinally movable manner. The actuation arrangement includes an actuation handle pivotally connected to the supporting frame to longitudinally drive the locking latch moving between a locked position an unlocked position. Moreover, the safety lock arrangement includes a locker member movably mounted on the supporting frame, wherein the locker member has a slider slot formed thereon to define a pusher surface and an opposed retracting surface, and a thermal activated arm substantially extended from the supporting frame to slidably pass through the slider slot of the locker member at a safety temperature, and adapted to deflect to push the locker member at the pusher surface at an elevated operation temperature.

Assignee:

Pixelligent Technologies, LLC - Baltimore MD

International Classification:

C08K 3/10
H01R 43/00

US Classification:

524403, 29825

Abstract:

Domain segregation of polymer blends or block copolymers in the presence of thermal conducting high aspect ratio nanocrystals leads to preferential placement of conductive filler either inside one domain, which promote the self-assembly of a thermal and/or electrical conducting pathway composed of high aspect ratio filler. The self-assembly of such thermal and/or electrical conducting pathway effectively enhances the thermal and/or electrical conductivity of the composite with significantly less amount of filler.

International Classification:

C08K 3/18
A61K 47/32

US Classification:

524432, 5147724

Abstract:

Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.
