A reusable food storage container includes bottom and top members, each having first and second portions. Each bottom member first portion includes a bottom wall with opposed side walls and an end wall extending between the side walls and extending upwardly from the bottom wall. Each bottom member defines an open end opposite its outside end wall and an open top. The bottom member portions are selectively coupled together using tab and channel structures. The top member portions each include a top wall having opposed end walls with an outer side wall connecting the end walls and extending downwardly from the top wall. The top member portions are selectively connected using tab and channel structures. Each top member defines an open side opposite its respective outside side wall and an open bottom. The top portion includes a circumference slightly larger than that of the bottom portion, enabling a nesting attachment.

Food storage container

The present invention provides a toolholder mountable on a lathe or other machine tool for supporting a cutting plate relative to a workpiece for cutting or shaping the workpiece. The toolholder including a body having a tapered tool base at one end thereof, the tool base defining a tool seat for supporting a cutting plate. A plug screw having a head defining threads on an outer surface thereof for engaging a threaded hole in the tool base is also provided. The plug screw further defining a shank extending eccentrically from the head, the shank being receivable through a mounting hole defined by the cutting plate for locating the cutting plate relative to the tool seat upon rotation of the plug screw relative to the tool base. A lock nut is provided for receiving a threaded end of the shank for securing the cutting plate to the tool base and toolholder.

Toolholder

The present invention is a buffer device that is designed and configured to successfully and adequately buff and polish any desired surface without causing fatigue for the user, as well as without creating any swirl marks. In order to provide for such a product, the present invention comprises a frame having a cylindrical body secured thereto. A motor is coupled to the cylindrical body to provide for the body to rotate about a normally horizontal axis that is parallel to the desired surface to be buffed, polished, and cleaned or the like. Secured to the cylindrical body is a buffing/cleaning pad fabricated from a conventional material.

Buffing apparatus

A scanning optical spectrometer with a detector array is disclosed, in which position of focused spot of light at the input of a dispersive element such as arrayed waveguide grating (AWG) with a slab input, is scanned using a micro-electro-mechanical (MEMS) tiltable micromirror so as to make the dispersed spectrum of light scan over the detector array coupled to the AWG. Sub-spectra recorded using individual detectors are concatenated by a processor unit to obtain the spectrum of input light.

Scanning spectrometer with multiple photodetectors

An optical packaging arrangement combines a planar lightwave circuit (PLC) having an array of waveguides thereon, an array of photodetectors on a substrate to receive light beams coupled out of the PLC by the output ports, and a collimating faceplate, having a plurality of glass cores, extending between the PLC and the photodetector array for coupling the output light beams to respective photodetectors. The faceplate forms a cover for a hermetic cavity encompassing the photodetectors. The PLC is disposed either co-planarly with the faceplate or transversely to it. Light from the PLC is tapped via a plurality of taps formed on the PLC for coupling to the photodetectors.

Planar lightwave circuit package

A planar lightwave circuit includes an arrayed waveguide grating (AWG), with input and output waveguides, partially curved array waveguides with respective length differences, and planar waveguide regions for focusing optical energy between the input/output and array waveguides. Optimal waveguide widths and spacing along the planar waveguide region facets are disclosed, which are largely determinative of AWG size and optical performance. Also disclosed are optimal cross-sectional waveguide dimensions (e.g., width and height); modified index of refraction difference between the waveguide core and cladding regions; and optimal array waveguide lengths, path length differences, and free spectral range. These features, especially when combined with advanced fiber attachment, passivation and packaging techniques, result in high-yield, high-performance AWGs (both gaussian and flattop versions).

Compact, low insertion loss, high yield arrayed waveguide grating

A package for optical components includes an inner package enclosing the optical component, and an outer package enclosing the inner package. A heater may be disposed in the inner package proximate the optical component to control its temperature, and to maintain this temperature control, the outer package creates an isolated air pocket around the inner package, which thermally insulates the inner package from the outside environment. The outer package is formed of a material having low thermal conductivity, to promote this insulating function. This package is especially useful if the optical component comprises a planar light-wave circuit (PLC), e.g. an arrayed waveguide grating (AWG), which requires tight temperature control and structural integrity to maintain the integrity of the optical paths.

Package for optical components

An optical component package, in which a transfer molded layer of material (e.g., syntactic foam in one embodiment) is formed at least partially around, or entirely around, the optical component to provide structural and thermal insulation around the component. The optical component may be a planar lightwave circuit (PLC), with a protective passivation layer formed between the PLC and the layer of syntactic foam, to de-couple stresses and thermal transfer between the PLC and the layer of syntactic foam. Strengthening caps, fiber assemblies, and a heater may be provided with the PLC assembly, around which the layer of syntactic foam can also be formed. The protective passivation layer can also be formed between these structures and the syntactic foam; in one embodiment between at least two strengthening caps formed on opposing edges of the PLC. The disclosed package provides numerous structural, thermal and size benefits.

Transfer molded packages with embedded thermal insulation

A redundant package for optical components includes an inner package enclosing the optical component, and an outer package enclosing the inner package. A heater may be disposed in the inner package proximate the optical component to control its temperature, and to maintain this temperature control, the outer package creates an isolated air pocket around the inner package which thermally insulates the inner package from the outside environment. The outer package is formed of a material having low thermal conductivity, to promote this insulating function. This package is especially useful if the optical component comprises a planar lightwave circuit (PLC), e.g., an arrayed waveguide grating (AWG), which requires tight temperature control and structural integrity to maintain the integrity of the optical paths.

Redundant package for optical components

An electric vehicle assembly circuit connected to a battery of an electric vehicle for charging the vehicle batteries during operation and thereby increasing the distance the vehicle is able to travel between battery charges. The vehicle batteries are divided into first, second, third and fourth sets of batteries. The electric vehicle assembly circuit includes a first processor connected to the first set of batteries, a first controller connected to receive power from said first processor and an alternator. A device is connected between the first controller and the alternator for driving the alternator. A second controller is connected to the alternator for charging the second and third sets of batteries during operation of the vehicle. A first converter connected to said alternator for providing a constant charge to the first set of batteries. A first relay is positioned between the first converter and the lights and horn of the vehicle for providing a constant power to the lights and horn. A second relay connects said first converter and a propulsion system of the vehicle providing power to the propulsion system during operation. An AC charger receives power from an external source for charging the first, second, third and fourth sets of batteries and a third relay disconnects the propulsion system from the first converter when the AC charger is receiving power from an external source.
