Abstract:

A submount substrate is used for the dual purposes of enabling simultaneous burn-in processing for a relatively large number of arrays of optical transmitters and enabling conventional dicing techniques to be used to form mounting-ready assemblies. In the preferred embodiment, the submount substrate is a silicon wafer that is specifically designed to provide connectivity between VCSEL arrays and burn-in equipment during the testing stage, but is also designed to be segmented and used in the final packaging stage. Because the submount is a silicon wafer, conventional integrated circuit fabrication techniques may be used to form conductive patterns that define array-receiving areas and that allow external circuitry to communicate with the various VCSEL arrays.

Abstract:

The present application discloses a multi-functional shredder that is capable of effectively destroying both paper documents and rigid/semi-rigid objects, such as CDs or DVDs. This multifunctional shredder comprises a housing; a drive system including at least one motor; and at least two shafts rotatably mounted within the housing and coupled to the drive system to enable the drive system to counter-drive the shafts in respective opposing rotational cutting directions. Each of the shafts includes positive cutter elements and negative cutter elements, configured to cooperate to shred articles as the shafts are rotationally counter-driven by the drive system in the respective rotational cutting directions thereof. The positive cutting elements on each shaft have positive cutting parts angled in the respective rotational cutting directions of the shafts, and the negative cutting elements on each shaft have negative cutting parts angled opposite the respective rotational cutting directions of the shafts.

US Classification:

385 88, 385 92, 385 94

Abstract:

Waveguide based connector systems for optically coupling a fiber optic cable and an optoelectronic device and a method of fabricating the same are described. In one aspect, a connector system comprises an optical waveguide and an optical turn assembly. The optical waveguide has a first end and a second end. The first end of the optical waveguide is connectable to the fiber optic cable in an orientation aligned with a line-side connection axis. The optical turn assembly has a first optical port that is connected to the second end of the optical waveguide in an orientation aligned with a device-side connection axis, a second optical port that is oriented to communicate optically with the optoelectronic device along a device communication axis substantially intersecting the device-side connection axis, and an optical turn system that is operable to guide light along a path between the first optical port and the second optical port.

Abstract:

A jack shaft garage door operator for opening and closing a movable garage door has a drive containing an electric motor. A rotatable jack shaft is connected to the drive unit to be driven thereby. A pull-up cable drum is connected to and driven by the jack shaft. A pull-up cable extends from the drum about which it is wound and connects to a bottom part of the garage door to raise the door. A pivoting arm is mounted near the jack shaft and provides tension to the cable. A shaft lock hub mounted on the jack shaft is engaged and locked by the arm if the tension in the cable drops. A stop is mounted on the garage door for engagement by the movable arm in the event that the door is opened without the cable being drawn in the cable drum.

US Classification:

424427

Abstract:

Biocompatible intraocular implants include a steroid and an auxiliary agent, where the auxiliary agent is present in an amount sufficient to lessen the severity of at least one side effect compared to the use of an otherwise identical implant lacking said auxiliary agent. The steroid and the auxiliary agent may be present on the same intraocular implant or on different implants. The steroid and auxiliary agent may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. Or, the steroid may be associated with a polymeric coating having one or more openings effective to permit the steroid to be released into an external environment. The implants containing the steroid and an auxiliary agent may be placed in an eye to treat one or more ocular conditions while reducing the side effects otherwise accompanying steroid use.

Abstract:

A multi-stage transport polymerization (“TP”) reactor useful for making a thin film for the fabrication of integrated circuits. One TP reactor has two distinct heating zones that facilitate the cracking of specific precursor materials. The multi-stage reactor comprises a first low temperature heating zone that heats incoming precursor materials to a temperature that is lower than the “cracking” temperature of the precursor. The second heating zone is maintained at a temperature useful for breaking the chemical bonds of a desired leaving groups in the selected precursor. Specialized heating bodies, which transfer heat to the precursor material in the low and high temperature zones, are used as elements of the invention that can simultaneously decrease the total volume and increase the inside surface area of the TP reactor. Chemistries of precursors used in the multi-stage reactor are also provided.
