Abstract: A device for use in a removing fluids and debris from a surgical wound and for location of nerves adjacent to the surgical wound comprises a hollow electrically conductive tube which has a lumen extending from the distal end thereof to the proximal end thereof. Openings are located at the distal end of the tube for suction removal of the fluid and debris. A handle located at the proximal end of the tube is provided for attachment of a second tube which is connected to a vacuum source.

Abstract: A fabrication method which forms vertical capacitors in a substrate. The method is preferably an all-dry process, comprising forming a through-substrate via hole in the substrate, depositing a first conductive material layer into the via hole using atomic layer deposition (ALD) such that it is electrically continuous across the length of the via hole, depositing an electrically insulating, continuous and substantially conformal isolation material layer over the first conductive layer using ALD, and depositing a second conductive material layer over the isolation material layer using ALD such that it is electrically continuous across the length of the via hole. The layers are arranged such that they form a vertical capacitor. The present method may be successfully practiced at temperatures of less than 200° C., thereby avoiding damage to circuitry residing on the substrate that might otherwise occur.

Abstract: A robotic arm and control system includes a robotic arm which moves in response to one or more command signals. One or more “active” fiducials are located on the arm, each of which emits its own light. A 3D camera having an associated field-of-view is positioned such that at least one fiducial and a target object to be manipulated are in the FOV. To determine their spatial positions, the arm fiducials are activated and the target object is preferably illuminated with a scanning laser; the camera produces output signals which vary with the spatial locations of the fiducials and target object. A controller receives the output signals and uses the spatial position information as feedback to continuously guide the arm towards the target object. Multiple active fiducials may be employed, each having respective characteristics with which they can be differentiated.

Abstract: A foldable microcircuit is initially a planar semiconductor wafer on which circuitry has been formed. The wafer is segmented into a plurality of tiles, and a plurality of hinge mechanisms are coupled between adjacent pairs of tiles such that the segmented wafer can be folded into a desired non-planar configuration having a high fill-factor and small gaps between tiles. The hinge mechanisms can comprise an organic material deposited on the wafer such that it provides mechanical coupling between adjacent tiles, with metal interconnections between tiles formed directly over the organic hinges, or routed between adjacent tiles via compliant bridges. Alternatively, the interconnection traces between tiles can serve as part or all of a hinge mechanism. The foldable microcircuit can be, for example, a CMOS circuit, with the segmented tiles folded to form, for example, a semi-spherical structure arranged to provide a wide FOV photodetector array.

Abstract: The invention relates to an arrangement and method for estimating the linear and nonlinear parameters of a model 11 describing a transducer 1 which converts input signals x(t) into output signals y(t) (e.g., electrical, mechanical or acoustical signals). Transducers of this kind are primarily actuators (loudspeakers) and sensors (microphones), but also electrical systems for storing, transmitting and converting signals. The model describes the internal states of the transducer and the transfer behavior between input and output both in the small-and large-signal domain. This information is the basis for measurement applications, quality assessment, failure diagnostics and for controlling the transducer actively. The identification of linear and nonlinear parameters Pl and Pn of the model without systematic error (bias) is the objective of the current invention. This is achieved by using a transformation system 55 to estimate the linear parameters Pl and the nonlinear parameters Pn with separate cost functions.

Abstract: An electro-osmotic pump includes a pump chamber having a wall fabricated of an electric double layer material, the surface area of the electric double layer material being high relative to the volume of the chamber. An electric potential applied across the material causes a fluid in the chamber to be transported through the wall. A nastic actuator includes the electro-osmotic pump and an actuator chamber, having a variable volume, coupled to the pump chamber. A superabsorbent polymer is disposed in the pump and actuator chambers, such that transport of the fluid into the pump chamber results in absorption of the fluid by the superabsorbent polymer, causing the actuator chamber to increase in volume. When the electric potential is applied across the superabsorbent polymer, the superabsorbent polymer expands, further causing the actuator chamber to increase in volume.

Abstract: Calibration methods and structures are provided for pipelined analog-to-digital converter systems. They are arranged to process samples of the digital codes with an algorithm that is preferably configured to repeatedly update an estimate of the transfer function with the difference between one of the input signals and the analog equivalent of the corresponding digital code. The calibration methods and structures are further configured to calibrate the transfer function of the converter stage wherein the samples are selected in accordance with various steps. These steps can include the step of injecting dither signals into a flash portion and an MDAC portion of the converter stage to thereby maintain dynamic range. They can also include the step of limiting the samples to those processed through a selected subrange of the subranges. They can further include the step of limiting the samples to those in which the absolute value of the input signals is less that 0.

Abstract: A lapping row tool comprising a plurality of bending nodes having a space between adjacent ones of said nodes and each of which has an end surface to manipulate a row of magnetic heads during lapping. A bridge extends along the end surfaces of the bending nodes and across the space between the adjacent bending nodes. The bridge provides a surface for holding the row of magnetic heads that prevents the flexing of the row into the space between the bending nodes during lapping while allowing the bending nodes to manipulate the row during lapping.

Abstract: A vanadium dioxide front-end advanced shutter device. The electronic shutter device is designed to protect receiver front-ends and other sensitive circuits from HPM pulse events such as HPM weapons, directed energy weapons, or EMPs. The shutter incorporates a transition material such as thin-film vanadium oxide (VOX) materials that exhibit a dramatic change in resistivity as their temperature is varied over a narrow range near a known critical temperature. A high-energy pulse causes ohmic heating in the shutter device, resulting in a state change in the VOX material when the critical temperature is exceeded. During the state change the VOX material transitions from an insulating state (high resistance) to a reflective state (low resistance). In the insulating state, the shutter device transmits the majority of the signal. In the reflective state, most of the signal is reflected and prevented from passing into electronics on the output side of the shutter device.
