    • A method for controlling an optical, path-to-sight link, the optical link including a source of light having a beam of light, a controllable beam steering device and an actuator to permit steering the light beam, the beam steering device being controllable by predetermined control signals. The method includes the following steps. The beam steering device is controlled so as to scan the beam of light in a first predetermined pattern. First direction is received data from a remote receiver including a light detector, the direction data corresponding to a direction of the beam at which the scanned beam of light is detected by the light detector. Responsive to the first direction data, a first beam direction is determined for data communication from the link to the receiver. The beam steering device is controlled to maintain a communications beam direction corresponding to the first beam direction. The beam of light is modulated with electronic signals.

    • A miniaturized sensor (100) that improves the confidence measure of a given sample reading by directing the flow of sample to the sensor/sample interface (117) and thus bringing the sample reliably in contact with the sensor's biosensing film. An inlet flow channel (105) extending from the bottom (125) of the sensor (100) to the sensing surface (120). The inlet channel (105) guides the sample to a cavity 115 formed at a housing surface (120) where it interacts with the film deposit (117). An outlet channel (110) extends from the cavity (115) to the bottom surface (125) and directs the sample outside the device. The light source (58), detector array (68) and interface (54) can be added to the structure providing a fully integrated miniaturized sensor. Various well known methods of manufacturing may be used including mill casting, split molding and double mold processes.

    • A multi-functional completion tool which may be lowered into a wellbore coupled to a length of tubing, and then utilized to test various lengths of the tubing at pressure. The tool may also function as a positive plug and may also be used to set the packer, and is also useable as a tubing self-filling tool. Various retention elements are disposed within the tool and configured to release at predetermined pressures, or within predetermined ranges of pressure, thereby transforming the tool from a first configuration to a second configuration depending on the desired function. The tool may also contain a pressure-regulating assembly for regulating the differential pressure across the assembly. The tool may also include an indicator assembly for confirming that the tool has entered a plugging configuration, typically by altering a pressure within the tubing, such alteration being detectible at a surface location.
