Abstract: A system includes more than one subsystem, each subsystem operating within a different subsystem frequency range, the subsystems comprising a circulator having three or more circulator ports and a direction of circulation, the circulator operating within a specific frequency range of the subsystem frequency range, and a filter, such as a bandpass filter, connected to at least one of the circulator ports. The filters each define a subsystem port and operate within the specific frequency range. Each subsystem port has a port index determined by the direction of circulation of the circulator within the subsystem. Each subsystem port has a specific port index that is connected to a common port having the specific port index. At least one of the circulator ports may be terminated to a matched load. Each subsystem circulator may comprise at least three circulator ports, with a filter connected to each of the circulator ports.

Abstract: A system and method for estimating needed medical supplies based on a selected predefined operational scenario. A predefined operational scenario may be modified, a new operational scenario may be built, or a predefined operational scenario may be imported from an external source. A computer-readable program, system and method is provided for enabling a user to produce a query concerning relationships between patient conditions, tasks and medical supplies needed in specific locations. The production of a report or query is performed by referencing a database containing data pertaining to patient conditions, functional locations at which patients are to be treated (triage, operating room, etc.), equipment available in defined functional areas, tasks associated with treatment of defined patient conditions, medical supplies needed to carry out each defined task, and relationships therebetween, and determining needed medical supplies based on use data input and data contained in the database.

Abstract: A method of determining an amplifier performance is provided. One embodiment establishes a number of amplifier performance constraints. A search is then conducted for an input and an output disk that satisfy the amplifier performance constraints. A vector index is then generated that includes a load reflectance SL and a generator reflectance SG at a number of different radio frequencies. The amplifier performance constraints are then input into the vector index and the load reflectances SL and generator reflectances SG that meet the amplifier performance constraints are determined.

Abstract: A scanning probe microscopy head may include a base portion, cantilevers coupled to the base portion, and at least one tip coupled to each of the cantilevers. At least two of the cantilevers and associated tips may be configured to perform a different scanning probe microscopy technique. The cantilevers may be positioned perpendicular to the base portion and may be coupled to the perimeter of the base portion. The base portion may include circuitry coupled thereto for providing electricity to the tips. The cantilevers may each be placed into a recessed slot along the perimeter of the base and secured to the base by a securing mechanism, such as a spring clip. The cantilevers may be operatively coupled to a linear positioner, such as a piezoelectric motor, coupled to the perimeter of the base for controlling the amount of protrusion of the cantilevers from the perimeter of the base.

Abstract: Various methods and systems directed to electromagnetic signal proximity detection are disclosed. For example, an EM detector may include an antenna array for sensing electromagnetic radiation produced by a source of radio-frequency electromagnetic radiation, one or more amplitude demodulation circuits coupled to the antenna array configured to perform an amplitude demodulation of one or more signals provided by the antenna array to produce one or more respective demodulated output signals, and an analysis circuit coupled to the amplitude demodulation circuit configured to determine at least one relative characteristic between the antenna array and the source of radio-frequency electromagnetic radiation. The relative characteristic may be the relative distance and/or angle between the antenna array and the source of radio-frequency electromagnetic radiation. The embodiments allow for signal source detection and location determination without knowledge of the frequency of a target emitter.

Abstract: A adaptive recursive method for detecting statistically significant changes in data performs steps that include: determining a mean and standard deviation for incoming data; flagging non-conforming data; detecting signals, trends, and/or shifts in the data, and resetting the mean and standard deviation under prescribed circumstances based on predetermined criteria, and then displaying statistics derived from the data.

Abstract: A loudspeaker motor structure uses variable geometry to change the effective magnetic field acting on the voice coil of the motor structure. A magnet generates the magnetic field, which couples into a front plate, a back plate, and a pole piece. In one loudspeaker, the front plate and the pole piece have notches and slots. Rotating the pole piece relative to the front plate varies the width of the gap between the pole piece and the front plate, and the effective magnetic field in the gap. In another loudspeaker, the pole piece moves up and down in relation to the back plate. This movement varies the magnetic coupling between the pole piece and the back plate and, consequently, the effective magnetic field in the gap between the pole piece and the front plate. Variations in the effective magnetic field in the gap result in variations of the loudspeaker parameters.
