Abstract: Provided is a method of operating a semiconductor device. A method of operating a semiconductor device includes storing secure data in a secure area of a memory in response to detecting a system failure; encrypting the secure data stored in the secure area by using a random key to generate encrypted secure data; storing the encrypted secure data in the secure area; and dumping the secure area and a non-secure area of the memory.

Abstract: A method for transferring variable isochronous data and an apparatus therefor are provided. The method for transferring variable isochronous data includes the steps of (a) determining isochronous transfer to be terminated when the bus is in an idle state for a time interval which is larger than an isochronous gap period, (b) detecting a residual gap having a time interval which is larger than the time interval of an isochronous gap and smaller than the time interval of a subaction gap, (c) checking whether bandwidth for the transfer of isochronous data remains when the residual gap is detected in the step (b), and (d) transferring the isochronous data when it is determined that the bandwidth remains in the step (c).

Abstract: The present invention discloses a system and method for providing an exhibition information service through wireless communication. In the system for providing the exhibition information corresponding to a request signal, when wireless connection devices receive a signal from a wireless terminal for transmitting or receiving data through air, the wireless connection devices output information corresponding to the received data through a network, and transmit information corresponding to the data input through the network to the wireless terminal through air. In addition, an exhibition information server processes the exhibition information service corresponding to the data input through the network. As a result, the user can read the exhibition information for the exhibits at a particular time by using the wireless terminal, even when he/she is moving.

Abstract: The present invention concerns biodegradable linear polyester urethanes as well as biodegradable crosslinked polyester urethanes issuing from the linear polyester urethanes in such a way that they are crosslinked by diisocyanate bridges. By varying the degree of crosslinking it is possible to adjust the physical, chemical and biological properties in the crosslinked polyester urethane as defined by the invention in a targeted manner. In particular, it is possible to vary the rate of biodegradation of said crosslinked polyester urethane because the biological degradation takes place at a slower rate as the degree of crosslinking increases. Furthermore, the object of the invention is a method of producing the polyester urethanes as defined by the invention, as well as its application in the form of sheets or foils, shaped rubber articles, containers, packaging materials, in the field of galenic pharmacy; and in the form of adhesives and adhesive tapes and the like.
