Filed:

Nov 4, 2009

Appl. No.:

12/612203

Inventors:

Celine Hu - Tiburon CA, US
Jianping Xu - Pleasanton CA, US
Hetian Gao - Fremont CA, US
Julie Perkins - Sunnyvale CA, US

International Classification:

C12Q 1/68
C07H 21/04
C12P 19/34

US Classification:

435 6, 536 231, 435 912

Abstract:

Methods and compositions which can be used to increase the strength and/or probability of forming a binding complex comprising a target molecule and a substrate are disclosed. In one aspect, linking molecules are disclosed which can be used to increase the number of intra-complex binding interactions. Covalent bonds can be introduced to further increase the strength of these binding interactions. Inter-complex cross-linking can be utilized in connection with these methods to further strengthen and stabilize the disclosed binding complexes.

US Classification:

506 30

Abstract:

Methods and compositions which can be used to increase the strength and/or probability of forming a binding complex comprising a target molecule and a substrate are disclosed. In one aspect, linking molecules having one or more members of a reactive pair are disclosed which can be used to increase the number of intra-complex binding interactions in a complex comprising a target molecule and a substrate. Intra-complex crosslinking and inter-complex crosslinking can be utilized in connection with these methods and compositions to further strengthen and stabilize the disclosed binding complexes.

International Classification:

B64G 1/00
F03H 1/00
B64G 1/40
B64G 1/42

Abstract:

Described herein is a thrust system for a vehicle that includes at least three electrical power controllers, at least four electrical switches each configured to receive electrical power from at least one of the at least three electrical power controllers, and at least three thrusters each configured to receive electrical power from at least one of the at least three electrical switches. The at least four electrical switches are operable to switch a supply of electrical power from any of the at least three electrical power controllers to any one of the at least three thrusters.

International Classification:

F03H 1/00

US Classification:

60202

Abstract:

A gridded ion propulsion system comprising two power controllers, four ion thrusters, and two switch assemblies. One switch assembly is connected to the two power controllers and to two of the four ion thrusters. The other switch assembly is connected to the two power controllers and to the other two ion thrusters. Each switch assembly has first and second switching states which can be selected to enable either power controller to supply power to any one of the four ion thrusters. Each switch assembly comprises a respective movable body and a respective multiplicity of switches which change state in unison when the movable body changes position. For example, the movable body may be a rotatable hollow shaft driven by a stepper motor.
