    摘要: The present invention provides methods and apparatus for freeze drying in which a solution, which can be a radioactive salt dissolved within an acid, is frozen into a solid on vertical plates provided within a freeze drying chamber. The solid is sublimated into vapor and condensed in a cold condenser positioned above the freeze drying chamber and connected thereto by a conduit. The vertical positioning of the cold condenser relative to the freeze dryer helps to help prevent substances such as radioactive materials separated from the solution from contaminating the cold condenser. Additionally, the system can be charged with an inert gas to produce a down rush of gas into the freeze drying chamber to also help prevent such substances from contaminating the cold condenser.

    摘要: A freeze dryer comprises a chamber having an opening through which containers can be inserted into the chamber, a door, and a mechanism for moving the door against the opening. A sealing mechanism comprises a first gasket extending around the opening, and a second gasket extending around the first gasket. The second gasket is moveable between a first position at which the first gasket forms an airtight seal with the door and a second position at which the second gasket forms an airtight seal with the door.

    摘要: Pre-authentication information of devices is used to securely authenticate arbitrary peer-to-peer ad-hoc interactions. In one embodiment, public key cryptography is used in the main wireless link with location-limited channels being initially used to pre-authenticate devices. Use of public keys in the pre-authentication data allows for the broadening of types of media suitable for use as location-limited channels to include, for example, audio and infrared. Also, it allows a range of key exchange protocols which can be authenticated in this manner to include most public-key-based protocols. As a result, a large range of devices, protocols can be used in various applications. Further, an eavesdropper is forced to mount an active attack on the location-limited channel itself in order to access an ad-hoc exchange. However, this results in the discovery of the eavesdropper.

    摘要: Magnetic resonance measurement methods for determining the mass of samples are provided in which magnetic field homogeneity is determined, compensation is provided for potential drifts in the measuring system, and the presence of metal in samples is determined. The methods include applying a magnetic field in a first direction in an interrogation zone for creating a net magnetisation within a sample located within the interrogation zone; applying an alternating magnetic field in a second direction in the interrogation zone for temporarily changing the net magnetisation of the sample located within the interrogation zone; monitoring energy emitted by the sample as the net magnetisation of the sample returns to its original state and generating an output signal having a characteristic which is proportional to the energy emitted; and comparing the output signal of the monitoring with other data.

    摘要: A system and method for sharing files securely includes server software on a first device configured to communicate with server software operating on one or more other preauthorized devices, such as a second device. The servers communicate with each other securely using cryptographic information exchanged during a preauthorization phase using a range-limited communication channel. The server on the first device obtains file information from the other preauthorized device(s) and combines the information with local file information from the first device. This combined file information is sent to client software operating on the machine, which presents the combined file information to users.
