Abstract: A bioreactor consumable unit (50; 500) comprises a bioreactor part (60); a fluid feed container part (80) integrally connected with the bioreactor part and including at least one fluid feed container (82) in fluid communication with the bioreactor (60); and an integral pumping element (100, 110; 160, 206) configured to enable fluid to flow from the at least one fluid feed container (82) to the bioreactor (60). The bioreactor part (60) includes a bioreactor chamber (62) and a stirrer (64) for agitation of a cell culture (66) in the chamber. The pumping element comprises a combination of a syringe pump (110) and an associated three-way valve (102). The bioreactor consumable unit (50; 500) may be inserted into a receiving station (20) of a cell culture module (10) for the processing and control of a bioreaction in the bioreactor chamber (62).

Abstract: A method for imaging the Earth's subsurface includes taking summed recordings of signals acquired by a plurality of seismic sensors disposed above the volume in response to repeated actuations of a seismic energy source. A travel time of seismic energy is determined from a position of the source to a selected image point in the volume and from the image point to each seismic sensor. A time-delayed scanline gather is generated from the travel times using a model of spatial distribution of acoustic properties of formations in the volume. A template image of backscattered energy from the image point is generated based on the model. The flattened scanline gather is singular value decomposed. The template image is projected onto the decomposed time-delayed scanline gather. Components from the projection are used to determine signal and interference. Weights are calculated for beamforming of the determined signal component.

Abstract: A method for determining position and orientation of a rotating wing aircraft (e.g. helicopter) with respect to a ground station includes transmitting an electromagnetic signal from the aircraft. The signal includes a plurality of electromagnetic signals, each signal having a different selected frequency. The signal is detected at an array of sensors disposed on the ground surface in a selected pattern. The array includes at least one reference sensor and at least three spaced apart time difference determination sensors. A difference in arrival time of the signals between the reference sensor and each of the time difference determination sensors is determined and a spatial position of the aircraft is determined from the time differences.

Abstract: An acoustic camera includes an acoustic transmitter disposed at one longitudinal end of a housing. The transmitter has a convex radiating surface. A diameter of the transmitter is about four times a wavelength of acoustic energy emitted by the transmitter. A plurality of acoustic receivers is disposed at spaced locations in a pattern extending laterally from the housing. A signal processor is in signal communication with the acoustic receivers. The signal processor is configured to cause the acoustic receivers to be sensitive along steered beams. The signal processor is configured to cause an end of the steered beams to move through a selected pattern within a beam width of the acoustic energy emitted by the acoustic transmitter. The signal processor is configured to operate a visual display device to generate a visual representation corresponding to acoustic energy detected by the acoustic receivers. A visual display device is in signal communication with the signal processor.

Abstract: A method for determining a position of a wireless electronic device within a volume includes detecting a signal transmitted by the wireless device during two-way communication to and from a first known position within the volume. The method further includes detecting the signal from at least three additional known positions within the volume, where the at least three additional known positions are spatially independent of each other. The method further includes determining a phase difference between the signal detected at the first position and the signal detected at each of the at least three additional positions, determining the position of the wireless electronic device using the phase differences, and at least one of displaying and storing the position of the wireless electronic device.

Abstract: A method for determining position of a mobile electronic device includes emitting an acoustic pulse from the position of the mobile electronic device. The acoustic pulse is detected at a known position at three spaced apart locations along each of at least two lines extending in different directions. The range and phase difference of the acoustic pulse between each of the detecting locations is determined. A relative position of the device with respect to the known position is obtained from the range and phase differences.

Abstract: Apparatus for making an acoustic analysis of a patient's body includes a glove device (12) with finger receivers (21-25) that receive the fingers of a caregiver, and sensors (51-53) that indicate the relative positions and orientations of the finger receivers. An acoustic transducer device (31-35) is mounted on each finger receiver, and possibly also (42) on the palm region (44) and other areas of the glove device. While transducer devices are pressed against the patient's body (62), electronic circuitry (112) generates electrical pulses that drive the transducers to transmit acoustic beams into the patient's body. A data processor (140) processes outputs from the transducers that represent acoustic echoes or transmitted beams received from regions of different densities in the patient's body. By mounting the acoustic transducer devices on finger receivers, the caregiver can rapidly and easily position the acoustic transducer devices at selected positions on the patient's body.
