Abstract: A method for protecting private content stored in a portable memory device are provided, wherein the portable memory device comprises a micro-controller unit, a USB connector, a memory array, a decoder, a storage for storing various application programs, and a backup power supply, characterized in that the method comprises steps of generating a protection signal in response to an initiating action and transmitting the signal to the micro-controller unit; recoverably deleting original file systems from the memory array USB the micro-controller unit in response to the received protection signal, and storing the original file system into the storage as a backup for the recovery purpose.

Abstract: A hydrogel dressing for covering or treating a wound, a surgical incision, a catheter insertion site or the like, comprising a non-fluid sheet material including a structure of cross-linked polymers and/or monomers having suspended therein an agent for controlling infection of the wound, the incision, the catheter insertion site or the like.

Abstract: A system for data communication purposes in electronic devices comprises a data bus comprising first, second, third and forth signal paths. A first control means generates a first state of a control signal in the presence of a clock signal in a first mode of operation. The first operation mode may be the normal operation mode of a consumer electronic apparatus. A second control means generates a second state of the control signal in the presence of a clock signal in a second mode of operation. The second operation mode may be the stand-by mode of the consumer electronic apparatus. The system can be easily integrated into existing systems utilizing e.g. a VFD protocol.

Abstract: The present invention relates to a method for determining the format of an optical recording medium (1) comprising one or more data, audio and/or video tracks in one or more sessions, and an apparatus for reading from and/or writing to optical recording media (1) using such method. It is an object of the present invention to propose a method for determining the format of an optical recording medium (1), which is robust against partially incorrect data on the recording medium (1).

Abstract: A dilute mixture of a large organic parent compound in an inert diluent is formed using a specially designed diffusion cell to control the amount of parent compound that is taken up by the diluent gas. The dilute mixture flows through a hot pyrolyzing tube where the parent compound is decomposed solely and totally by a gas phase unimolecular reaction into equimolar amounts of reactive gas and a stable reaction product. The method produces an internal standard for determining the concentration of the reactive gas since the stoichiometry of the reaction requires that the concentration of the reactive gas be equal to the concentration of the other reaction product, which can be easily calibrated by standard methods.
