Abstract

A parallel dilating-filters switched-capacitor filter bank is described in simulation of the cochlea. Area-saving is achieved by filter-sharing, effective sum-gain amplifier designs, and using area efficient nth-order filter designs, and in particular using a biquadratic filter design using charge-differencing. The structure is easily expandable to include more channels by extending with additional filters and output amplifiers, or by using several chips with different sampling frequencies in parallel connection.

Abstract

An audio signal representative of an acoustic signal is provided to an auditory model. The auditory model produces a high-dimensional feature set based on physiological responses, as simulated by the auditory model, to the acoustic signal. A multidimensional analyzer orthogonalizes and truncates the feature set based on contributions by components of the orthogonal set to a cortical representation of the acoustic signal. The truncated feature set is then provided to classifier, where a predetermined sound is discriminated from the acoustic signal.

Abstract

An apparatus, system, and method are provided for a lateral two-terminal nanotube device configured to capture and generate energy, to store electrical energy, and to integrate these functions with power management circuitry. The lateral nanotube device can include a substrate, an anodic oxide material disposed on the substrate, and a column disposed in the anodic oxide material extending from one distal end of the anodic oxide material to another end of the anodic oxide material.

Abstract

Surfaces having a hierarchical structure--having features of both microscale and nanoscale dimensions--can exhibit superhydrophobic properties and advantageous condensation and heat transfer properties. The hierarchical surfaces can be fabricated using biological nanostructures, such as viruses as a self-assembled nanoscale template.

Abstract

As the critical dimensions of devices continue to shrink, novel methods and apparatus must be developed to overcome device limitations at smaller length scales. Microelectromechanical systems (MEMS), such as micro-fabricated generators, motors or other electromechanical devices, may require suitable rotational speeds for operation on a micron to sub-micron length scale.

Abstract

ZVS DC/DC converter for converting voltage between a battery and a DC link in a hybrid energy storage system and method thereof is a bi-directional DC/DC converter with zero voltage soft switching (ZVS) capability. This results in a higher efficiency and provides reduction of switching losses due to higher switching frequencies.

Abstract

A method of fabricating articles, such as an oxide ceramic article, is disclosed. The method includes cutting an oxide ceramic workpiece in a cutting zone and applying a cutting fluid to the cutting zone. The cutting fluid includes an aqueous solution which contains a sufficient amount of a boron compound to effectively provide lubrication. The boron compound is selected from the group consisting of boric acid, alkali metal borates, aluminum borate, and mixtures thereof.

Abstract

A setup planning technique is provided in which a family of parts to be manufactured is identified, and the setup constraints imposed by the various bending operations in the part family are determined. The setup constraints may define or describe spatial constraints on the sizes and locations of various tooling stages in the setup. After identifying setup constraints, setup plans are generated that satisfy all setup constraints. Any setup plan that satisfies all setup constraints may then be utilized to accommodate every part in the part family.

Abstract

Devices, systems and methods for magnetically assisted agent delivery are included. These devices, systems, and methods make use of a plurality of magnets or magnetic configuration. Two magnets are arranged such that the two magnetic fields overlap and can cancel at the location of the desired node point without canceling around that point.

Abstract

Systems and methods are disclosed for directing magnetizable particles comprising therapeutic agents to a target volume, or for guiding magnetizable particles comprising therapeutic agents from a first target volume to a second target volume, at a distance using a magnetic field, to enable the treatment of diseased areas including areas deep inside a patient's body.
