Electrical detectors for microanalysis
InactiveUS20050118705A1Improve sensitivity and accuracyHigh sensitivityBioreactor/fermenter combinationsBiological substance pretreatmentsMicroelectrodeElectricity
Apparatus and methods for performing microanalysis of particles using a microelectrical-mechanical system (MEMS) chip to electrically interrogate the particles. The MEMS chip is typically manufactured using known lithographic micromachining techniques, employed for example, in the semiconductor industry. A substrate carries a plurality of microelectrodes disposed in a detection zone and spaced apart along an axis of a microchannel. The microchannel is sized in cross-section to cause particles carried by a fluid to move past the electrodes in single file. Impedance is measured between one or more pairs of electrodes to determine the presence of a particle in the detection zone. In certain embodiments used in cell manipulation, an electroporation signal may be applied between one or more pairs of electrodes to enhance permeability of a cell membrane. A structural arrangement may be provided to introduce a treatment substance into the microchannel in the vicinity of a cell, which may be restrained for a period of time in a treatment zone.

Finger-mapped character entry systems
ActiveUS20140298266A1Fast inputMove quicklyInput/output processes for data processingPhysical medicine and rehabilitationComputer graphics (images)
A finger-mapped gesture system is a user interface method and apparatus for rapid data input on a touch-sensitive surface. The user gestures by holding the hand stationary relative to the surface and moving the fingers primarily by extension and flexion on the surface. Each finger gestures on a gesturing area instead of selecting among keys. Individual gestures are constructed from finger actions that each independently parameterize the gesture. In combination, the particular fingers gesturing and the parameters that the fingers gesture indicate the input that the user intends. On devices that do not directly identify fingers, fingers are identified via a finger map that, after calibration to a person's hand, associates each finger with a gesturing area. Gestures are otherwise independent of where they are performed, freeing users from having to look at their fingers to target visual elements. The system is optimized for rapid character data entry.

Method and apparatus for currency discrimination
InactiveUS20060210137A1Efficient discriminationIncrease speedComplete banking machinesPaper-money testing devicesEngineeringOptical sensing
An improved method and apparatus for discriminating between currency bills of different denominations uses an optical sensing and correlation technique based on the sensing of bill reflectance characteristics obtained by illuminating and scanning a bill along one of its dimensions. A series of detected reflectance signals are obtained by sampling and digitally processing, under microprocessor control, the reflected light at a plurality of predefined sample points as a currency bill is moved across an illuminated strip with a preselected dimension parallel to the direction of transport of the bill. The sample data is subjected to digital processing, including a normalizing process, whereby the reflectance data represents a characteristic pattern that is unique for a given bill denomination and incorporates sufficient distinguishing features between characteristic patterns for discriminating between different currency denominations. A plurality of master characteristic patterns are generated and stored using original bills for each denomination of currency to be detected. The pattern generated by scanning a bill under test and processing the data samples is compared with each of the prestored master patterns to generate, for each comparison, a correlation number representing the extent of similarity between corresponding ones of the plurality of data samples for the compared patterns. Denomination identification is based on designating the scanned bill as belonging to the denomination corresponding to the stored master pattern for which the correlation number resulting from pattern comparison is determined to be the highest, subject to a bi-level threshold of correlation.

The programs continually monitor a subject's ability to distinguish the processed language elements, and adaptively configures the programs to challenge and reward the subject by altering the degree of processing. Through adaptive control and repetition of processed speech elements, and presentation of the speech elements in a creative fashion, a subject's temporal processing of acoustic events common to speech are significantly improved.

InactiveUS20090028554A1High receiver bandwidthLow costSynchronisation error detectionDigital computer detailsSignal qualityTime delays
Monitoring an optical signal comprises sampling the optical signal from two or more distinct tap points to retrieve a sample set. Multiple such sample sets are obtained over time. A joint probability distribution or phase portrait of the sample sets is assessed for indications of optical signal quality. The tap distinction can be polarisation, for example to determine OSNR, or frequency. The tap distinction can be a time delay, which can enable diagnostic differentiation between multiple impairments, such as OSNR, dispersion, PMD, jitter, Q, and the like. Machine learning algorithms are particularly suitable for such diagnosis, particularly when provided a two dimensional histogram of sample density in the phase portrait.

A raindrop sensor includes an image sensor and an image processor. The image sensor captures an image of a windshield from inside a vehicle. The image processor performs a frequency analysis of the image to detect a high-frequency component in the image. When the high-frequency component is detected, the image processor detects a width of a change region where a change in gradation of the image occurs. When the width of the change region is within a predetermined range corresponding to a diameter of a raindrop, the image processor determines that the raindrop is on the windshield. Even when a foreign matter such as a water stain appears as the high-frequency component as a result of the frequency analysis, the raindrop and the foreign matter can be distinguished from each other based on the width of the change region.
