Abstract: A switching circuit includes a bridge rectifier to receive voltage inputs across a load and an optical isolator to receive a logic input signal and generate an output signal based on the logic input signal. The high speed switching circuit also includes a field effect transistor (FET) with a source connected to a negative output of the bridge rectifier, a drain connected to a positive output of the bridge rectifier through a second load, and a gate driven by the output signal of the optical isolator. First and second resistors connect the voltage inputs to the gate of the FET through first and second diodes. The first and second resistors and the first and second diodes limit current flowing to the gate of the FET. A Zener diode connected to the gate of the FET limits voltage to the gate of the FET below a maximum voltage rating of the FET.

Abstract: A passive clearance control limits thermal expansion between stator components relative to rotor components. A control ring controls clearance in a passive manner and is located on or adjacent to stationary components which thermally expand during engine operation. The control ring is formed of material having low coefficient of thermal expansion such as CMCs (Ceramic Matrix Composites) and therefore limits, inhibits or restrains expansion of the adjacent stator components as temperatures increase. Limiting expansion of the stator component reduces rotor/stator clearances and limits parasitic leakage of fluid along the flowpath through the engine core.

Abstract: System and method of performing a crowdsourced online idea generation and peer review process for main topic of interest for a client, often involving large numbers of expert participants and a panel of expert moderators. Qualified participants are drawn from a database of system members, and moderators are often qualified client employees or consultants. A server, capable of hosting various threaded discussions on various related topics, is first initialized with various related topics, seed ideas and comments. Participants are then given access for a predetermined time, and contribute new ideas, peer review other participant's ideas, and vote ideas up and down. Moderators review progress, and vote to highlight ideas and comments, close ideas, and delete off-topic contributions. Various voting analysis algorithms draw attention to promising ideas. Participants are rewarded on a daily basis for contributing ideas, comments, and votes. The system produces new ideas that are peer reviewed and prioritized.

Abstract: A system and method of managing a server based multi-member or crowdsourced scouting process for client sponsored technology, product, or prior art searches. Clients submit search requests with non-confidential and often confidential parts, and associated search constraints, often via electronic client workspaces. This is stored in the system database. Members and their associated member information are also stored in the system database. Potentially interested members are contacted, given non-confidential information, and NDA submitting members then are provided with any confidential part of the search. Members then utilize their own networks to generate search leads. Member submitted leads are then evaluated either automatically or via administrator system dashboards, and passing leads given to clients for review or approval. Efficiency is enhanced by allowing various types of member-client feedback during the process. Funds or other rewards are dispersed to those members who submit client approved leads.

Abstract: Internet web server based method/system for providing confidential, moderated, crowdsourced problem solving resources to solve various problems. A crowdsource database of various skilled individuals interested in acting as problem solvers and team facilitators is provided, along with a database of client proposed problems, divided into non-confidential and confidential problem statement sections, key skills needed, and other criteria. These criteria are used as an index to the crowdsource database, and potential matches found. An administrator uses a server provided dashboard GUI, and the non-confidential problem statements, to pick among the various proposed matches, determine interest, and form small facilitator moderated teams. After suitable NDA, the confidential problem statement is revealed, and the teams interact confidentially with the client through the server. Facilitator moderation, problem restatement, and other methods reduce burden on the client and improve solution quality.
