Abstract: A fingerprint reader includes a display screen composed of an array of energy emitting pixels covered by a transparent cover, at least one sensor coupled along an edge of the display screen, a display driver directing the array of energy emitting pixels of the display screen to illuminate in a predetermined sequence, and a microprocessor in communication with the display driver and the at least one sensor, in use, and when at least one finger is placed on the transparent cover and the display driver is activated, energy from each energy emitting pixel sequentially illuminated is reflected off the fingerprint to the at least one sensor. The energy received at the at least one sensor is at different intensity levels depending upon the ridges and valleys of the at least one fingerprint. The at least one sensor sends a signal to the microprocessor regarding the energy intensity level, from which the microprocessor creates a fingerprint image as the energy emitting pixels are sequentially illuminated.

Abstract: A device and method for controlling the flow of a gaseous fuel from a fuel supply to a pressurized combustion chamber. A fuel pump is included in the gas train from supply to chamber. The fuel pump increases the pressure of the gas to allow efficient injection into the chamber. The pump is modulated to control the fuel flow. Both alternating current and pulse-width-modulated direct current signals may be used to control the flow. The pump may be a piston pump or a diaphragm pump. Feedback may be provided from sensors that determine operating parameters of the engine and such sensor signals may be used by the controller to maintain a parameter, such as temperature, at a specified value. An acoustic filter can be included in the gas train to significantly reduce gas flow pulsations generated by the pump. This filter improves the uniformity of the combustion process.

Abstract: A system for facilitating tracking of a moving object is disclosed. The object has a feature associated therewith which is illuminated with ambient light. The system includes illumination means for illuminating at least the feature of the object with a tracking light. The system also includes detection means for detecting an image of the feature and for outputting signals corresponding to movement of the image. The signals have a first component due to the tracking light and a second component due to the ambient light. Further, the system includes filter means for filtering the second component from the signals and for outputting the first component of the signals so that the ambient light is discriminated from the tracking light and the moving object can be tracked using the first component of the signals. In one embodiment, in which the object is a human eye, the system may also include logic means for receiving the filtered signals, optionally adjusting the first component of the signals for perceived differences in the intensity of illumination across the illuminated area of the feature, and for generating tracking signals based thereon and may include means for directing a laser beam upon the eye based on the tracking signals to maintain a substantially centered condition between the optical axis of the laser beam and the visual axis of the eye.

Abstract: A first query and a second query, both of which were submitted by a first user to identify information that satisfies a single information need of the first user, are received. The first query and the second query are stored in association with one another and based on a chronological order in which the first query and the second query were submitted by the first user to generate a first query reformulation path. A query is received from a user and more than one query reformulation path is accessed. The received query is compared with queries included in the accessed query reformulation paths to identify a relationship between the received query and a query included in a relevant query reformulation path. One or more prevalent end points is determined based on the relevant query reformulation path and at least one of the prevalent end points is presented to the user.
