摘要:
An apparatus is provided for synthesis and collection of higher order chemical compounds from lower order precursors. The apparatus includes a first silent electric discharge reactor configured to synthesize an intermediate product (e.g., disilane) from a precursor chemical (e.g., monosilane). A second silent electric discharge reactor is connected downstream of the first reactor. This second reactor is configured to convert the intermediate product into the higher order chemical compound (e.g., trisilane). Multiple condensation traps are also connected to receive effluent from the second reactor, which will generally include the compound of interest as well as unreacted precursor and intermediate product. In the illustrated embodiment, a parallel second condensation traps is also included to shunt flow and continue collection while the chemical of interest is removed for purification. Moreover, parallel second condensation traps for the intermediate product and unreacted (or recombined) precursor allow continued collection while the contents of the first traps are recycled in the reactor(s).

摘要:
A system for protecting networks from vulnerability exploits comprises a security engine operable to receive a packet destined for a user's network and forward the packet to at least one host virtual machine for processing. The security engine is further operable to forward the stored packet to the user's internal network based upon a result of the processed packet. A method of securing a network from vulnerability exploits is described. The method comprises receiving a packet destined for a user's internal network; forwarding the packet to at least one virtual machine based upon a virtual machine configuration table; processing the forwarded packet on the at least one virtual machine; and releasing the packet to the user's internal network based upon results of the processing.
摘要:
Controller assemblies and packaging for electronic control systems of electric motors utilized in utility vehicles or other power equipment are disclosed. The controller assemblies are packaged for robust design and heat dissipation, while collectively housing the controllers, switches and sensors needed to operate multiple motors performing different functions, or the same function in serial.
摘要:
A method for detection of a network address translation (NAT) device in a network is described herein. An edge network device detects a first packet at an edge port of the edge network device. A second packet is detected at the edge port of the edge network device. It is determined whether a time to live (TTL) value associated with the first packet is different from a TTL value associated with the second packet. Where the TTL value associated with the first packet is different from a TTL value associated with the second packet, it is determined that a NAT device is connected to the edge port. Where the TTL value associated with the first packet is the same as a TTL value associated with the second packet, it is determined that a NAT device is not connected to the edge port.

摘要:
A liquid injector is used to vaporize and inject a silicon precursor into a process chamber to form silicon-containing layers during a semiconductor fabrication process. The injector is connected to a source of silicon precursor, which preferably comprises liquid trisilane in a mixture with one or more dopant precursors. The mixture is metered as a liquid and delivered to the injector, where it is then vaporized and injected into the process chamber.

A method for fabricating a micro-sensor device comprising the steps of fabricating on a parent substrate (10) at least one sensor element (21); forming an interconnect layer (32) having first and second surfaces remotely to the parent substrate (10) so as to enclose the at least one sensor element (21) between the first surface and the parent substrate; providing a plurality of electrical interconnections (33) between the at least one sensor element and a plurality of terminations at the second surface of the interconnect layer, said terminations adapted to interface with a readout substrate. The method may comprise the further step of providing a readout substrate (38) having a plurality of input connections (40) disposed on a first surface thereof, said input connections (40) arranged so as to substantially correspond with the terminations at the second surface of the interconnect layer, and interfacing the plurality of terminations with the corresponding input connections to form an integrated assembly.
摘要:
A fluid application device comprising a holder; a tube connected to the holder; and a porous fluid applicator contained within the holder wherein the holder contacts at least a portion of a bottom surface of the porous fluid applicator. The device allows the dispensing of fluid onto a target area without contacting a non-target area.
