Abstract:

An economical, repeatable, and non-invasive method and apparatus for the calibration of implantable pressure sensors that can minimize patient discomfort and risk of infection. In one embodiment, a calibration system for calibrating a first pressure sensor coupled to a management device and implanted into a human patient is provided. The calibration system includes a mouthpiece, a pump, a second pressure sensor, and a computer. The pump provides a positive pressure into an airway of the human patient via the mouthpiece. The second pressure sensor measures the airway pressure of the human patient, and the computer is coupled to the pump and monitors pressures measured by the first and second pressure sensors. Here, the computer also calculates one or more calibration constants based on the pressures measured by the first and second pressure sensors and provides the calibration constants to the management device to calibrate the first pressure sensor.

International Classification:

H01H 51/32

US Classification:

361184

Abstract:

Frequency addressable micro-actuators having one or more movable resonating elements actuators, such as cantilevers, can be forced into oscillation by, e.g., electromagnetic actuation. The movable structure is designed to latch at a certain amplitude using one of several latching techniques, such as a near-field magnetic field. In operation, the movable element is driven into resonance, producing a large amplitude, which results in the structure latching. Through resonance, a small force applied in a repeating manner can result in the latching of the actuator, an operation which would normally require a large force. If two or more units, each with different harmonic frequencies, are placed under the same influence, only the one with a harmonic response to the driving force will latch. A single influencing signal may be used to latch more than one device on demand by tuning the frequency to match the natural frequency of the device of interest.

Abstract:

Micro capacitive switches and methods of manufacturing micro capacitive switches at variable nominal capacitance value using micro-structures on the contact plates of the same dimension. In a preferred embodiment, a separately manufactured contact plate can be mounted to a movable magnet in order to be actuated to “on” and “off” state of the capacitive switch. Depending on the contact plate's surface condition, variable contact capacitance at “on” state can be precisely specified by geometrical properties of the micro-structures on the surface, such as the density, size and depth.

US Classification:

382166, 382167

Abstract:

The present invention relates to a system and method for reducing image artifacts for a CMOS camera used as an optical detector for a line confocal fluorescent imager. The method for reducing image artifacts in a monochromatic image comprises subtracting RGB channel offset mismatch; and correcting random row offset for each row. Preferably, the method also comprises correcting random column offset and gain. Optionally, the method also comprises clipping of defective pixels, and/or subtracting dark current. When the monochromatic image is a fluorescence image, the method also comprises a step of compressing CMOS camera noise. Also provided are a system for reducing image artifacts in a monochromatic image from a CMOS camera, as well as an image artifact reduction system for a CMOS camera-based line confocal fluorescent microscope.

Abstract:

A method and system of determining an output label rationale are provided. A first generator receives a first class of data and selects one or more input features from the first class of data. A first predictor receives the one or more selected input features from the first generator and predicts a first output label. A second generator receives a second class of data and selects one or more input features from the second class of data. A second predictor receives the one or more selected input features from the second generator and predicts a second output label. A discriminator receives the first and second output labels and determines whether the selected one or more input features from the first class of data or the selected features of the one or more input features from the second class of data, more accurately represents the first output label.
