Abstract: A method for determining the position of a mobile station (820) within a cellular telephone system having a plurality of base stations (810). A signal is transmitted at a low power level from the mobile station (820). The strength of the signal is then temporarily increased from the low power level to an increased power level, and the signal is temporarily transmitted from the mobile station (820) at this increased power level. While the signal is being temporarily transmitted from the mobile station (830) at the increased power level, the signal is used to make at least a first positional measurement.      The position of the mobile station (830) is determined in accordance with the first positional measurement.

Title: Genetic modification of primate hemopoietic repopulating stem cells
Inventor: EINERHAND MARKUS PETER WILHELM
IPC: C12N5/08
Filed: 1997-11-19
Granted: 2007-02-06
Abstract: Genetic modification of pluripotent hemopoietic stem cells of primates (P-PHSC) by transduction of P-PHSC with a recombinant adeno-associated virus (AAV). The genome of the recombinant AAV comprises a DNA sequence flanked by the inverted terminal repeats (ITR) of AAV. The DNA sequence will normally comprise regulatory sequences which are functional in hemopoietic cells and, controlled by these regulatory sequences, a sequence coding for a protein or RNA with a therapeutic property when introduced into hemopoietic cells. Preferred examples of DNA sequences are the human lysosomal glococerebrosidase gene, a globin gene from the human .beta.-globin gene cluster, a DNA sequence encoding an RNA or protein with anti-viral activity, the .alpha. 1-antitrypsin gene and the human multidrug resistance gene I (MDRI). The invention provides for effective gene therapy with PHSC of primates, in particular humans.

Granted: 2007-05-01
Abstract: A control and suspension system for a retractable covering mounted on a rotating element includes an apparatus for mechanically limiting over-extensions of the covering and an apparatus for mechanically limiting over-retractions of the covering, The apparatus for limiting over-retraction includes a threaded shaft and an internal, roll-bar-support wheel treaded on the threaded shaft. An intercepting ledge comprising part of the internal, roll-bar-support wheel, and a stopping ledge comprising part of the threaded shaft. Over retraction of the covering is prohibited when the intercepting ledge impacts the stopping ledge. The apparatus for limiting over-extension includes a roll-bar-end support wheel having a down limit stop pivotally mounted thereto. When the covering material is fully extended, the limit stop rotates away from the roll-bar-end support wheel and impacts a substantially annular channel wall associated with an end cap, thereby preventing further rotation of the roll bar and thus further extension of the covering. The control and suspension system also includes an apparatus to compensate for any undesirable skewing of the covering that might occur. The skew adjustment apparatus includes a skew adjustment plate that is slidably mounted in channels on an end cap. A threaded skew adjustment plug is threadingly engaged with the skew adjustment plate such that rotation of the skew adjustment plug moves the skew adjustment plate. Finally, the control and suspension system also includes a bottom rail that attaches to the bottom of the covering by trapping a portion of the covering between a compression plate and a bottom plate.
