| 20090010805 | ASSAYING DEVICE AND METHOD OF TRANSPORTING A FLUID IN AN ASSAYING DEVICE - 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. | 01-08-2009 |
| 20090273692 | REFERENCE DATA ENCODING IN IMAGE SENSORS - 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. | 11-05-2009 |
| 20110019048 | SENSOR AND SENSOR SYSTEM FOR A CAMERA - A sensor module has first and second sensor arrays formed on a substrate, with the first and second sensor arrays adapted to share common readout circuitry and shared read out for a pair of sensors on a single array. | 01-27-2011 |
| 20110019247 | IMAGING SYSTEM AND METHOD - An imaging system for a scanner includes a sensor and a rod lens. The sensor has a linear array of photosensitive elements arranged in three rows and disposed at an angle such that the rows are at different distances from the lens and the object being scanned. When changes in focus occur, for example in scanning a book or a 3D object, the photosensitive elements giving the sharpest image are selected. The angle is achieved by mounting the sensor to a PCB via solder bumps arranged along one side of the sensor. | 01-27-2011 |
| 20110057906 | POINTING DEVICES - A touch pad uses a plurality of optical mouse type sensors. The sensors are optimized for detection of motion along the predominant direction of a user's finger as the finger is moved around the touch pad. A first one of the sensors functions to optically sense motion in a first direction, while a second one of the sensors functions to optically sense motion in a second, different, direction. The first and second directions are oriented a closed, for example, circular, path. | 03-10-2011 |
| 20110134033 | ELECTRONIC DEVICES - 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. | 06-09-2011 |
| 20110141078 | AMBIENT LIGHT DETECTION - Ambient light is detected by a photodiode circuit by measuring the time taken for a digital output of the photodiode circuit to change state in response to exposure of a photodiode of the photodiode circuit to that ambient light. A nominal time for state change is calculated based on photodiode circuit characteristics. Furthermore, an effective time for the photodiode circuit digital output to change state is determined in a calibration mode where the photodiode has been disconnected and a reference current is applied to the circuit. An illumination value of the detected ambient light is then calculated as a function of: the measured time, the effective time and the nominal time. | 06-16-2011 |
| 20110157418 | IMAGE SENSOR ARRAYS - 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. | 06-30-2011 |
