Abstract:
An array of image sensors are connected in a daisy chained arrangement. The sensors in the array are addressed on the basis of the number of pixels each of them processes.
Abstract:
Data is encoded on an image sensor that has a plurality of pixels including one or more bio-sensing pixels and one or more data encoding pixels. The method includes applying a covering material selectively to the data encoding pixels depending on the data to be encoded, the covering material having a detectable difference in opacity relative to having no covering material present. The method includes reading the data encoding pixels, in the presence of light, and decoding data according to a pre-determined scheme depending on the presence of the covering material on the data encoding pixel. As bio-reagents are typically applied after manufacture of the image sensor, the image sensor can have information encoded for electronic detection subsequent to manufacture.
Abstract:
The image sensor includes a plurality of pixels, arranged in rows and columns to form a pixel array, each pixel having a pixel output. The image sensor includes at least two column bitlines for each pixel column, each column bitline connected to each pixel output in the pixel column and to a common readout amplifier. In one embodiment, the bitlines are not in the same plane and multiple bitlines are positioned one above the other, maximizing pixel efficiency.
Abstract:
A mobile communications device includes a radiofrequency antenna, a navigation pad and a signal processor. The radiofrequency antenna, navigation pad, and signal processor cooperate to encode and transmit motion signals from the navigation pad to a computer so that the mobile communications device functions as a pointing device therefore.
Abstract:
A sensor for an optical device includes an array of pixels in rows and columns which detect and process illumination falling thereon so as to identify inputs generated by a user on a surface of the optical device. A second reset period of variable length between a black calibration phase and an integration phase occurs in a processing cycle of a frame for each pixel, wherein the length of the second reset period is adjusted based on the ambient light conditions.
Abstract:
An assaying device includes one or more detectors, a transporter and inlet that is connected to the one or more detectors by a one or more channels. The transporter includes one or more sealed, vacuum-containing chambers being connected to the channels, wherein each of the chambers includes an electrically activated puncture. The puncture is configured to puncture a wall of a chamber and cause a differential pressure in the one ore more channels, and thereby transport a fluid from the inlet to the one or more detectors.
