Abstract: Payload systems for processing chemical substances under various gravity levels, such as hypergravity and/or microgravity. The payload systems may include a hypergravity thermal payload system configured to enable melt or cooling of a sample under hypergravity. Alternatively, or in addition, the payload systems may include a gravity-independent thermal payload system for enabling melt or cooling of a sample under various gravity levels, such as microgravity. Alternatively, or in addition, the payload systems may include a hypergravity crystallization payload system configured to enable crystallization of a chemical substance under hypergravity. Alternatively, or in addition, the payload systems may include a gravity-independent crystallization system configured to enable crystallization of a chemical substance in various gravity levels, such as microgravity.

Abstract: A technique includes measuring a first pressure of well fluid in a first region. The well fluid is produced from a formation into the first region. A second pressure of well fluid is measured in a second region. The second region is isolated from the first region, and the well fluid in the second region is in communication with the formation characteristics (skin, horizontal permeability or vertical permeability, as examples) of the formation is determined from the first and second measured pressures.

Abstract: An orientation detector arrangement is adapted to detect the orientation of a first component relative to a second component, preferably during endoscopic surgery. The first component is a transmitter which may be worn on a surgeon's head. The transmitter is adapted to transmit a plurality of unique identifiable signals along mutually diverging beams. The second component is a detector which is adapted to distinguish between the individual signals transmitted by the transmitter. The detector is connected by a control circuit to an endoscopic camera which is, in turn, connected to provide an image on a display screen. The detector and the associated control circuit are able to control movement of the endoscopic camera in response to movement of the surgeon's head.
