| 20090062820 | METHODS AND DEVICES FOR TREATING OBESITY AND GERD BY INTUSSUSCEPTING A PORTION OF STOMACH TISSUE - Described here are devices and methods for intussuscepting a portion of stomach tissue. Typically the intussusception is created at a position near, but distal to the gastroesophageal junction, and a pouch capable of storing a volume (from about 0 cc up to about 100 cc) is created proximal the intussuscepted tissue. In this way, the amount of food that may be ingested is reduced, helping to ameliorate GERD symptoms, and aiding in weight loss efforts. Some of the devices described here include an expandable member and at least one suction inlet. In these devices, the expandable member is expanded to create a proximal cavity into which the stomach tissue is pulled (e.g., using suction), thereby creating the intussusception. | 03-05-2009 |

| 20120019400 | MULTI-FUNCTION REMOTE CONTROL DEVICE - In an embodiment, a method for operating a target media device is described. The method includes receiving a user command by a remote control device for operating a target media device, where a signal to operate the target media device is not stored on the remote control device when the user command is received. Data associated with the user command is transmitted by the remote control device to a second media device and signal information, associated with the signal to operate the target media device, is received by the remote control device from the second media device. The signal to operate the target media device is transmitted by the remote control device to the target media device, where the target media device performs a function based on the signal received from the remote control device. | 01-26-2012 |

| 20100291842 | POLISHING HEAD ZONE BOUNDARY SMOOTHING - A method and apparatus for chemical mechanical polishing of substrates, and more particularly a method and apparatus related to a carrier had for use in chemical mechanical polishing is provided. In one embodiment the carrier head assembly comprises a base assembly for providing support to the substrate, a flexible membrane mounted on the base assembly having a generally circular central portion with a lower surface that provides a substrate mounting surface, and a plurality of independently pressurizable chambers formed between the base assembly and the flexible membrane, comprising an annular outer chamber and a non-circular inner chamber, is provided. | 11-18-2010 |
| 20120021673 | SUBSTRATE HOLDER TO REDUCE SUBSTRATE EDGE STRESS DURING CHEMICAL MECHANICAL POLISHING - Embodiments of the present invention generally relate to methods for chemical mechanical polishing a substrate. The methods generally include coupling a first substrate to be polished to a dummy substrate, and removing a portion of the backside of the first substrate to reduce the thickness of the first substrate. The first substrate and the dummy substrate are positioned in a carrier head assembly comprising an inflatable membrane and a support ring. The first substrate is placed in contact with a polishing pad to reduce the surface roughness of the backside of the first substrate. The support ring restricts lateral movement of the inflatable membrane to prevent the first substrate from contacting an interior surface of the carrier head assembly. The support ring is sized to allow vertical movement of the inflatable membrane within the carrier head assembly. | 01-26-2012 |

| 20100098725 | METHODS FOR CULTIVATING CELLS, PROPAGATING AND PURIFYING VIRUSES - The present invention provides novel serum-free cell culture medium and methods for cultivating MDCK cells. In particular, non-tumorigenic MDCK cells. The present invention also provides methods for producing influenza viruses (e.g., particularly cold-adapted, and/or temperature sensitive, and/or attenuated influenza viruses) that eliminate the need for a cell culture medium exchange step. The novel medium and methods are useful to grow influenza viruses, in cell culture to high titer. The present invention further provides purification methods for purifying influenza viruses with high overall recovery of live virus and result in levels of host cell DNA (HCD), host cell protein (HCP) and non-specific endonuclease (e.g., Benzonase), which are below the specifications required by regulatory agencies. The immunogenic compositions can be used to actively immunize subjects or to generate antibodies for a variety of uses, including passive immunization and diagnostic immunoassays. | 04-22-2010 |

| 20100263039 | Accessing Method and Multimedia System Using Thereof - The access method includes the following steps. Firstly, multimedia data is accessed with a multimedia access device located on a local network, which connected to a public network via a network address translation (NAT) or firewall device. Next, first communication link between a portal server and the multimedia access device is established. Then a piece of punch-through information indicating whether the multimedia access device can punch through the NAT/firewall device is obtained in response to an inquiry command provided by a client device. Next, when the multimedia access device cannot punch through the NAT/firewall device, the multimedia data is pushed from the multimedia access device to the portal server and the multimedia data pushed to the portal server is further pulled from the portal server to the client device, so that multimedia data transmission between the client device and the multimedia access device can be obtained. | 10-14-2010 |
