Abstract: A rotatable nacelle includes an engine inlet configured to receive air and an inlet air management system (IAMS). The IAMS includes a primary inlet configured to selectively allow air to flow into a duct associated with the engine air inlet via the primary inlet and a secondary inlet configured to selectively allow air to flow into the duct associated with the engine air inlet via the secondary inlet. The secondary inlet is configured to receive an air filter.

Abstract: Described are techniques to establish an on-demand, secure, point-to-point tunnel between a source device of a source network to a target device of a target network. The target network may not be visible to the source network. The target network includes a tunnel client and a tunnel server may be a perimeter device of the source network. The tunnel client may send a first message to the tunnel server. Data may be transmitted from the source to target device by including the data in a return message in response to the first message. The first message and the return message may be sent over one or more “heartbeat” connections which are continually established and torn down to transmit data between the two networks, and the source and target devices therein.

Abstract: A university recruiting system and database allow collaboration of university career center staff, university students, and employers. Career center software functions enable career center staff to create and manage university student accounts and employer accounts. Employer software functions enable the employers to create job postings, deploy targeted job postings across multiple schools, access university student profiles and conduct candidate search across multiples schools, and manage job applications accessible by multiple schools. University student software functions enable the students to create student profiles, upload job search related documents, and perform job searches across multiple job listings and job content repositories.

Abstract: With current WDM technology a plurality of individual data channels exist on each fiber. Each of these data channels must be individually monitored in these WDM systems to ensure data signal quality. Monitoring of these signals is accomplished with the use of an optical performance monitor (OPM). An accurate known reference source is required for the OPM to provide reliable monitoring of signal data. The invention couples a reference signal simultaneously with a data signal and provides this combined optical signal to an OPM monitor for the purpose of obtaining high accuracy wavelength data at low cost.

Abstract: A spectrum, time and protocol optical power monitor is disclosed. This device utilizes a same photodetector to perform spectral optical monitoring of an incoming optical signal, as well as performing timing and protocol monitoring for preselected wavelength channels. Advantageously the device uses a same passband tunable optical filter for both the spectrum and timing/protocol measurements. The spectral response of the filter passband is deconvolved from the spectral scan in order to achieve improved spectral scan resolution, and the timing and protocol measurements are not degraded by the passband of the filter.
