摘要： An array in which an external control feature for normalization has been designed and tested for its ability to mimic the range of observed expression levels for a test set of oligos. The external control probes span a series of concentrations. They are spatially randomized across a grid of an array. The series of concentrations is duplicated in a given grid. The individual grid layout and number of control and external normalization features per grid have been designed to cope with sources of both systematic error and spatial variation.

摘要： A dipole hydrophone which includes a radiation target for acoustic energy and a counterbalancing mass. A first multilaminar magnetostrictive arm is connected to the radiation target at its center gravity and a second multilaminar magnetostrictive arm is similarly connected to the center of gravity of the counterbalancing mass. The lower portion of each arm is slotted to define two legs, and a permanent magnet, in conjunction with the slotted structure forms a closed magnetic path for flux. Windings for sensing a change in flux are slipped over the leg portions, yielding a high gain device. The two arms are connected by a coupling member which is compliantly suspended from a support structure.

摘要： A Tonpilz transducer having head and tail masses with an interposed active transducer section. The transducer unit is positioned within a housing which has a shoulder portion upon which rests a snubber member which extends to a position just behind the head mass. The transducer is supported from the head mass by means of a thin fiberglass tube which extends from the rear of the head mass and engages a flange portion of the snubber member in the vicinity of the housing shoulder. The housing has a waterproof covering as does the head member with the covering of the head member being secured to the covering by means of a removable strap such that the transducer assembly may be disassembled for repair.

摘要： An acoustic homing torpedo having an array of transducers wherein each transducer has a head mass, tail mass, and a main active element therebetween. An auxiliary active element is placed on the tail mass so that when given a predetermined signal it will cause the main element to provide a corresponding output signal so as to simulate the reception of an actual acoustic wave. By energizing the main element, the response of the auxiliary element may be examined for testing the transducer and the array in a transmit mode of operation.

摘要： A control system for a Tonpilz transducer which is positioned between the transducer and the transducer drive amplifier. The control system determines the head velocity of the transducer from the input current and voltage and utilizes this determination in a feedback arrangement to maintain proper transducer excitation.

摘要： A transducer assembly which includes a plurality of staves releasably arranged around the periphery of a torpedo. Each stave includes a transducer backing member such as foam polyurethane to simulate an air backing, and a solid acoustically transparent transducer support member, such as polyurethane, disposed in front of it. A curved reflector made up of a plurality of sheets of onionskin paper is positioned between, and compressed by, the backing and transducer support members. A plurality of transducer active elements is arranged vertically within the transducer support member with the arrangement imparting a certain desired directivity pattern to receiving beams associated with such apparatus.

摘要： A dipole hydrophone having a differential pressure sensing unit, for example, a multi-laminar bender disc, within a liquid filled housing. Two liquid filled acoustic waveguides form extensions of the housing and include pressure sensing ports. A mass of predetermined value is connected to the sensing unit and with a predetermined separation between sensing ports, the mass value is chosen so that the sensing unit response to acceleration is very nearly equal and opposite to its response due to the inertial mass of the liquid.
