Abstract: The invention features an apparatus and method for transmitting a file. The apparatus includes a file splitter that splits the file into a plurality of message segments. Each message segment includes an address of the destination. The apparatus also includes a file encapsulator. The file encapsulator encapsulates at least one of the plurality of message segments. The encapsulation conceals the address of the destination during transmission of the at least one encapsulated message segment to one or more trusted nodes. The trusted nodes retransmit the message segments to the destination for reassembly of the file at the destination.

Abstract: The invention features an apparatus and method for transmitting a file via a communications network. The apparatus includes a file processor that converts a file into N message segments. The file can be reassembled from a subset of any M of the message segments, where N and M are positive integers, N is greater than M, and M is greater than or equal to 1. The apparatus includes a message segment transmitter. The transmitter transmits at least M of the N message segments to a receiver for reassembly of the file after receiving M of the N message segments.

Abstract: An optical spectrometer system has a central axis, a detector having a detector surface disposed at one end of the system and located at a focal plane of the optical spectrometer system. A cold stop is associated with the detector for permitting entrance of target source radiation onto the detector surface while blocking background radiation from surroundings. A cooling device is coupled to the detector for cooling it and the cold stop to a predetermined low temperature. A flat plate is provided and has an spectrometer slit formed in it, the plate having a flat surface facing the detector, the flat surface being coated with a highly reflective, low emissivity material. Fore-optic focusing lenses or mirrors are located in front of the flat plate for focusing radiation onto the slit on the flat plate between the fore-optic focusing and the collimating lenses. The collimating lenses between the flat plate and the cold stop collimate the light from the slit and form a pupil at the cold stop.

The power driving control system includes a first speed detection device for detecting the rotational speed of the pedals actuated by the rider's feet and a second speed detection device to detect the rotational speed of the rear wheel of the bicycle which incorporates a rear derailleur system, and a processor-based controller for receiving the signals from the two speed detection devices and controlling the electrical power supplied from a battery set to the motor in response to the ratio of the two rotational speeds, which may be varied in accordance with the riding condition of the bicycle so that the motor is controlled in a power-efficient way.

Abstract: A device for creating a panoramic field of view comprises a first light passing incident surface which is a cylinder surface and a second incident surface which is a mirror surface onto which light passing through the first surface impinges. A third incident surface onto which light from the second incident surface impinges is provided and the third incident surface being an aspherical transmission surface. A recollimating element for presenting a pupil plane depiction of a panoramic field of view is also provided. Various embodiments may include single or double lens devices with a second lens provided for the purpose of recollimating light.

Abstract: A die attach procedure for SiC uses the scrubbing technique to bond a SiC die to a package. A first layer is formed on the SiC die. This first layer, preferably of nickel, bonds to the SiC die. A second layer, preferably amorphous silicon, is then formed on the first layer. The second layer bonds to the first layer, and forms a eutectic with the material, usually gold, plating the package when the SiC die is scrubbed onto the package.

Abstract: A method of aligning a gate and a source of a silicon carbide static induction transistor comprising the steps of depositing an oxide layer over the transistor, forming oxide spacers from the oxide layer where the oxide spacers are adjacent the source, depositing a metal layer over the transistor and removing the oxide spacers so that the resulting gates are accurately aligned with the source.

Abstract: A tool handle mounting structure including a tool head having a fixed coupling cap, a handle having a tubular front end fastened to the coupling cap by a screw joint, and a sleeve fixedly mounted around the tubular front end to hold a sliding lock, wherein when the sliding lock is moved forwards after the handle is coupled to the coupling cap of the tool head, the handle is locked; when the sliding lock is moved backwards, the handle is unlocked, and can be turned reversely and disconnected from the coupling cap of the tool head.

Abstract: An optical sensor head (400) for providing an optical sensor with a hyperhemispherical field of view is disclosed. The optical sensor head (400) includes first and second lenses (430 and 440), each of the lenses (430 and 440) having a planar surface (434 and 444) and a convex surface (432 and 434). The sensor head (400) further includes a film (420) positioned between the lenses (430 and 440) for splitting the light beams impinging thereon.

Abstract: An improved MOS photodetector having polysilicon gate material which is made more transparent to visible light by the addition of up to 50% carbon, and preferably about 10% carbon. The surfaces of the polysilicon-carbon gates are oxidized to form a silicon dioxide dielectric layer, thus eliminating the need to deposit a separate dielectric layer for isolation of adjacent gates in an overlapping gate array. The elimination of a separate dielectric layer permits all gates to be formed directly on the substrate dielectric layer, thus providing a uniform drive voltage requirement across the array.

Abstract: A process for forming an insulating layer of silicon dioxide in a silicon substrate that surrounds and electrically insulates a semiconductor device is disclosed herein. The process comprises the steps of forming a recess on the outer surface of the silicon substrate that encompasses the site of the semiconductor device by photo-resist patterned reactive ion etching, and then removing silicon on the surface of the resulting recess whose crystal structure has been damaged by the reactive ion etching. Next, dopant atoms are selectively deposited on the surface of the recess so that the surface of the recess might be rendered into a porous layer of silicon when immersed in hydrogen fluoride and subjected to an electrical current. Prior to the porousification step, silicon is epitaxially grown within the walls of the recess to form the site for a semiconductor device.
