A method for forming a single-phase multi-element film on a substrate in a reaction zone by PEALD repeating a single deposition cycle. The single deposition cycle includes: adsorbing a precursor on the substrate in the absence of reactant and plasma; decomposing the precursor adsorbed on the substrate by an inert gas plasma; and reacting the decomposed precursor with a reactant gas plasma in the presence of the inert gas plasma. The multi-element film contains silicon and at least two non-metal elements constituting a matrix of the film, the precursor contains silicon and optionally at least one non-metal element to be incorporated in the matrix, and the reactant gas contains at least one non-metal element to be incorporated in the matrix.

A system and method for enabling information providers using a computer network such as the Internet to influence a position for a search listing within a search result list generated by an Internet search engine. A database stores accounts for the network information providers. Each account contains contact and billing information for a network information provider. In addition, each account contains at least one search listing having at least three components: a description, a search term comprising one or more keywords, and a bid amount. The network information provider may add, delete, or modify a search listing after authenticated login. A search term relevant to the content of the web site or other information source to be listed is first selected. A search listing includes the search term and a description. A bidding process occurs when the network information provider enters a new bid amount for a search listing. The system and method then compares the bid amount with all other bid amounts for the same search term, and generates a rank value for all search listings having that search term. The rank value determines where the listing will appear on the search results list page that is generated in response to a query of the search term by a searcher.

A single-phase multi-element film constituted by at least four elements is formed on a substrate by plasma-enhanced atomic layer deposition (PEALD) conducting one or more process cycles. Each process cycle includes: (i) forming an integrated multi-element layer constituted by at least three elements on a substrate by PEALD using at least one precursor; and (ii) treating a surface of the integrated multi-element layer with a reactive oxygen, nitrogen, and/or carbon in the absence of a precursor for film formation so as to incorporate at least one new additional element selected from oxygen, nitrogen, and carbon into the integrated multi-element layer.

A crosswind kite system adapted to operate in an alternate mode in high winds. The system may operate at reduced efficiency in high winds in order to moderate loading on the system during those high winds. The system may use multi-element airfoils which are actuated to reduce the coefficient of lift of the airfoils in order to moderate loading in high wind conditions. Other flight aspects may be controlled, including flying the crosswind kite in side slip to induce drag which may lower loading on the system.

A self calibrating dipole microphone formed from two omni-directional acoustic sensors. The microphone includes a sound source acoustically coupled to the acoustic sensors and a processor. The sound source is excited with a test signal, exposing the acoustic sensors to acoustic calibration signals. The responses of the acoustic sensors to the calibration signals are compared by the processor, and one or more correction factors determined. Digital filter coefficients are calculated based on the one or more correction factors, and applied to the output signals of the acoustic sensors to compensate for differences in the sensitivities of the acoustic sensors. The filtered signals provide acoustic sensor outputs having matching responses, which are subtractively combined to form the dipole microphone output.

A resonant switched power converter having switching frequency controlled in response to an output voltage thereof achieves over-current protection such as at start-up or under short circuit conditions using a resonant tank circuit which provides a notch filter in addition to a band pass filter. A additional band pass filter provided in the resonant tank circuit achieves increased power transfer to a load and reduced circulating resonant currents and conduction losses. The inductances of the preferred LCLCL tank circuit or other tank circuit with two pass band filters and a notch filter may be integrated into a single electrical component.

In a cellular mobile telecommunications system the position of a mobile station can be estimated in terms of its bearing and range from a cell site. A multi-element direction finding antenna at the cell site receives signals from the mobile station and a receiver circuit estimates the bearing using the relative phase of signals received at different antenna elements and estimates the range by measuring round trip delay of signals to and from the mobile station. Motion of the mobile station can introduce errors into the bearing estimate due to frequency offset and frequency spread when element sampling is non-simultaneous. Compensation for these errors is introduced by using signal samples successively received at the same antenna element to estimate Doppler frequency offset and spread. It is necessary to ensure accurate calibration of the direction finding antenna and the receiver circuit. This is done by injecting calibration signals into the circuit near the antenna or into the antenna itself from a near field probe. Other aspects of calibration, such as antenna position, are calibrated using a remote beacon. A beacon emulating a mobile station but at a fixed, known location, or a beacon at an adjacent cell site may be used.

A method of clamping a suture pair, including biasing a row of adjacent flexible elements to a first position in which an opening slot is formed therealong; receiving the suture pair into the opening slot; and removing the biasing such that the adjacent flexible elements move to positions which hold the suture pair in a tortuous path.

A system and method using a multi-element digital beamformer for detection and mitigation of spoofer and repeater threats to GPS that would not be addressed by baseline signal-to-noise (SNR) maximization algorithms is disclosed. GPS correlators and processing are applied to multiple beam outputs to detect and locate spoofer and repeater threats. In the beamformer processing, detected threats can be spatially nulled, even in the presence of traditional high power jamming, by modifying the normal sample covariance matrix to introduce synthetic nulls. A digital complex weighting system multiples each input channel by a complex (gain/phase) weight and adds the weighted channels together to form beams that the GPS receiver can use to reacquire the satellites in use without knowledge of platform attitude or the antenna manifold.
