Filed:

Jul 30, 2007

Appl. No.:

11/881836

Inventors:

Samuel Altman - Menlo Park CA, US
Nicholas Sivo - Palo Alto CA, US
Mark Jacobstein - San Francisco CA, US
Brian Knapp - Mountain View CA, US

Thomas Pernikoff - Mountain View CA, US

International Classification:

H04Q 7/20

US Classification:

455457000

Abstract:

Embodiments of a location sharing network manager process are described. The process is executed on a server computer coupled to a plurality of mobile communication devices over a wireless network. Each mobile device is a location-aware mobile communication device. The process determines the geographic location of a mobile communication device operated by a user within an area, displays a map representation of the area around the mobile communication device on a graphical user interface of the mobile communication device, and superimposes on the map the respective locations of one or more other trusted users of mobile communication devices coupled to the mobile communication device over the network. A security component allows users to establish trusted relationships by requiring mutual consent and disclosure of identifier and phone number information for each trusted user. Location information can be blocked among trusted users or obfuscated on the display of the mobile devices of the other users.

International Classification:

H05H 900
H05H 700

US Classification:

328233

Abstract:

Apparatus for normalizing and maximizing the performance of a drift tube on the operational axis of a drift tube linac. The apparatus features drift tube positioning through structure which includes orthogonally disposed, facially complementary datum surfaces, interposed which surfaces are dimensionally stable, clamped shim structure. Also offered is independently attachable/detachable (non-dedicated in place) adjustment mechanism employable to effect adjustments in the usual post-coupler structures associated with drift tubes.

James M. Potter - Los Alamos NM

Assignee:

AccSys Technology, Inc. - Pleasanton CA

International Classification:

H01J 2510

US Classification:

315505

Abstract:

A compact proton-beam therapy linac utilizing a linear, cascaded organization including a proton source, a radio-frequency-quadrupole (RFQ) linac coupled to the output of the source, a stepped-frequency (around 500- to around 100-MHz), low-peak-beam-current (around 100- to around 300-. mu. A) drift-tube linac (DTL) coupled to receive the output of the RFQ, and a plural-stage, low-peak-beam-current stage-switchable, side-coupled linac (SCL) coupled to the output of the DTL for producing the ultimate output proton-therapy beam.
