摘要:
Methods and apparatus are disclosed for processing data packets using a router and a proxy in order to transparently proxy a connection between a client and a server. One method involves mapping a TCP connection to a connection ID and sending a segment from the TCP connection to a proxy, including the connection ID, a direction value and an identifier of an assigned proxy application, such that the segment appears to be from the connection. The method further involves a proxy creating and reading from an IP socket which corresponds to the segment, the connection ID, direction and assigned proxy application and then spoofing the segment using the connection ID, a second direction value, and an identifier of the assigned proxy application.

An object with a dynamically changeable configuration is provided. The outer surface configuration and/or the weight displacement configuration can be dynamically changed to alter the characteristics of the object, which can be a toy, such as a football, baseball or flying disc. To change the outer configuration of the object, a cover having an outer surface and at least one aperture therethrough is provided. A surface changing member, such as a bladder, is urgable into the at least one aperture to dynamically change the outer surface of the object. To change the weight displacement of the object, the main body includes a first chamber and a second chamber therein where fluid, such as gas or liquid, can flow therebetween. The positioning of the fluid within the first chamber and the second chamber is controlled by a pump and valve system. As a result, the weight displacement of the object is dynamically changeable.

An adapter for use with a low volume PUF sampler is described. The adapter is affixed over the open end of a PUF (polyurethane foam) sample cartridge. Sample tubing is affixed to an aperture in the adapter, and the free end of the sample tubing is then positioned at a desired sample location such as within an aircraft interior. As a vacuum is applied to the PUF cartridge, the adapter allows air collected at the sample point to pass through the tubing and through the interior of the PUF cartridge while preventing air surrounding the PUF cartridge from being drawn into the PUF cartridge except through the sample tubing. In this manner the sample point of a desired air sample can be selected at a point remote from the PUF cartridge. Additionally, use of multiple PUF cartridges and adapters allows the simultaneous collection of separate air samples.
摘要:
The present invention relates to novel halohydrin dehalogenase polypeptides and the polynucleotides that encode them. These polypeptides are useful in the production of 4-substituted-3-butyric acid derivatives and vicinal cyano, hydroxyl substituted carboxylic acid esters. The invention also provides related vectors, host cells and methods.

An adjustable-resistance anti-siphon device for a cerebrospinal fluid shunt is provided. The device has a substantially rigid housing having an internal cavity which contains a first chamber and a second chamber, the first chamber having at least one flexible wall, an inlet port and an outlet port, the ports passing through apertures in the housing; the second chamber being gas-filled and being in pressure communication with at least a portion of the at least one flexible wall of the first chamber; and gas pressure control means connected to said gas-filled chamber whereby the pressure in said gas-filled chamber may be adjusted.
