    摘要: A handoff key is provided for facilitating a hand off of a wireless terminal from a first access point to a second access point. The handoff key may be generated by a server and communicated to the first and second access points. Alternatively, the handoff key may be generated one of the access points and transmitted to the other access point. The first access point may transmit the handoff key to the wireless terminal before the handoff. Shortly after the handoff, the wireless terminal and the second access point may communicate data encrypted with the handoff key. Later, an authentication server may authenticate the wireless terminal, causing the second access point to provide the wireless terminal with a session key. Thereafter, the wireless terminal and the second access point may communicate data encrypted with the session key.

    摘要: Enzyme substrates in aqueous liquids are continuously measured by introducing a sample containing the substrate to be determined into a current of buffer solution, reacting the substrate on an immobilized enzyme and measuring, in a measurement chamber, a physical change in the solution brought about by the reaction, wherein a current of buffer solution containing the sample to be determined is passed alternatingly (i) directly through the measurement chamber with the production of a reference signal and (ii) first over the immobilized enzyme and thereafter through the measurement chamber with the production of a measurement signal, and relating the reference signal to the measurement signal to indicate the enzyme substrate initially present.

    摘要: Porous tablets are produced by mixing the tablet components with a liquid solvent which is inert towards the components of the tablet and which freezes at a temperature from about -30 to +25.degree. C, the solvent constituting about 5 to 80% by weight of the total mixture, introducing the mixture into an inert cooling medium at a temperature low enough to solidify the solvent, pressing the mixture including the solidified solvent into tablets at a temperature below the freezing point of the solvent, and then evaporating the solvent from the tablets. Advantageously the solvent is water, cyclohexane, benzene and/or tert.-butanol, optionally containing alcohol. The tablets readily disintegrate in liquid.
