IPC: G06F13/00
Filed: 1998-11-26
Granted: 2002-06-11
Abstract: Provided is a device and method for preventing firmware of computer system from virus invasion including a control circuit for receiving at least a common purpose output signal and a data input signal and outputting a writing signal, and a non-volatile memory for receiving the writing signal for memorizing the firmware. When the control circuit checks that the common purpose output signal matches up a pre-defined logic, it makes the data input signal and the writing signal the same. This invention aims at firmware to use hardware for preventing virus invasion. It proceeds writing only when inputting specific utility program. Therefore, it is not like software prevention that needs to update virus codes continuously and has low efficiency when the software checks increase.

Title: Reliquefaction of pressurized boil-off from pressurized liquid natural gas
Inventor: KIMBLE E LAWRENCE III
IPC: F25B9/02
Filed: 1999-10-12
Granted: 2001-12-11
Abstract: A process is disclosed for reliquefying boil-off gas produced by pressurized liquid natural gas. In this process, refrigeration duty is provided to a heat exchanger by means of a refrigeration cycle. Pressurized natural gas is cooled by the heat exchanger and then expanded to a lower pressure to produce a liquid stream that is passed to a first phase separator. A boil-off vapor is passed through the heat exchanger and it is then compressed and cooled before being recycled back through the heat exchanger. The compressed, cooled boil-off gas is then expanded and passed to a second phase separator. A vapor stream produced by the second separator is removed from the process. A liquid stream produced by the second phase separator is passed to the first phase separator to produce a pressurized liquid having a temperature above about -112 DEG C and a pressure sufficient for the liquid to be at or below its bubble point.
