Abstract: An optoelectronic integrated circuit comprises a substrate, a multilayer structure formed on the substrate, and an array of thyristor devices and corresponding resonant cavities formed in the multilayer structure. The resonant cavities, which are adapted to process different wavelengths of light, are formed by selectively removing portions of said multilayer structure to provide said resonant cavities with different vertical dimensions that correspond to the different wavelengths. Preferably, that portion of the multilayer structure that is selectively removed to provide the multiple wavelengths includes a periodic substructure formed by repeating pairs of an undoped spacer layer and an undoped etch stop layer. The multilayer structure may be formed from group III-V materials. In this case, the undoped spacer layer and undoped etch stop layer of the periodic substructure preferably comprises undoped GaAs and undoped AlAs, respectively.

The intelligent product transfer and conveyance system for a processing facility ensures a continuous flow of a plurality of good products at sufficiently high speeds from an inspection process to subsequent stations for subsequent individualized packaging. The processing facility may comprise a contact lens manufacturing line for manufacturing spherical or toric type ophthalmic contact lens products.

Abstract: A unitary removable barrier for installation in a cylindrical water line to selectively block the water line to passage of water therethrough. The unitary removable barrier is composed of a single piece body having at least one cylindrical section sized to receive upstream and downstream pipes of the water line. A unitary planar disk is molded with the cylindrical section and is of a circular circumference which completely blocks the water line when in place but which is selectively removable from the cylindrical section thus removing the barrier to the passage of water through the line.

Abstract: A thin, stretchable chemical vapour protective garment worn next-to-skin is disclosed. The protective undergarment is made of material that stretches and is capable of efficient elimination of air spaces between the undergarment and the user's body, thus enabling the user to wear other operational clothing over top.

Abstract: A tilt steering wheel in a vehicle is provided which can be locked in selected positions by a mechanism that includes a rod having pivot connections with stationary and movable components of the steering column. A rotatable locking sleeve encircles the rod to form a rigid connection between the rod and one of the pivot connections. Mesh teeth on the rod and sleeve prevent the sleeve from moving in the elongated direction. By rotating the sleeve on the rod it is possible to shift the teeth out of mesh such that the rod can move longitudinally to set the steering column in a selected position. The sleeve has a slot with major and minor portions and in the locking position the minor portion captures a pivot shaft of the steering column and prevents relative movement of the rod with respect to the pivot shaft.

Abstract: An assembly for selectively blocking a drain to the passage of water. A drain emanating from a substantially circular opening in a basin, sink or tub is provided with a substantially cylindrical member releasably connected to the basin, sink or tub. The substantially cylindrical member is provided with a fluid inlet for receiving a pressurized fluid and an expandable bladder located within the substantially cylindrical member in fluid communication with the fluid inlet, wherein the bladder is sized and positioned such that when expanded, it blocks the drain to the passage of water. A mechanical pump is provided having a pump chamber and a stem emanating from it such that when the stem is moved, fluid pressure is applied to a hydraulic line connected to the fluid inlet for selectively expanding the bladder.

Abstract: A chemical protective hood designed to be worn over a respirator in a manner such that it is located between a helmet and the respirator. The hood has a skirt portion of filter barrier material containing an opening with edges configured to surround and fit against a respirator's facepiece. A top portion of the hood is formed of a thin single layer that fits under the helmet and is configured to match the curved inner surface of the helmet. The thin single layer allows the helmet to be comfortably donned without requiring any modification to be made to the helmet.

Abstract: A stopper for selectively blocking a drain to the passage of water. The drain has an inlet, an outlet and a substantially cylindrical throat between the inlet and outlet. A control means is provided for selectively feeding control fluid under hydraulic pressure to the cylindrical throat whereupon an expandable bladder located within the cylindrical throat selectively expands in fluid communication with the control fluid to block the drain and thus act as a stopper.
