Patent number: 10354081Abstract: Interprocess communication between processes that run on a host operating system of a computer is performed by way of a protected temporary file. File access operation on the temporary file is hooked to detect writing to the temporary file. When a process writes a message to the temporary file, a verification is performed to determine whether or not the process is authorized to access the temporary file. When the process is authorized to access the temporary file, the process is allowed to write the message to the temporary file. This allows another process that is intended to receive the message to read the message from the temporary file and act on the message. Otherwise, when the process is not authorized to access the temporary file, the process is blocked from writing the message to the temporary file.Type: GrantFiled: January 5, 2017Date of Patent: July 16, 2019Assignee: TREND MICRO INCORPORATEDInventors: Chuan Jiang, Weichao Dai, Zhifeng Du, Yuncao Tian, Sen Jiang

Patent number: 8170140Abstract: An active-set PAR reduction method has low computation cost and delay. Peak canceling, by adding up the original signal and the peak canceling signal, is done only after the final peak canceling signal that can reduce all peaks of the resultant signal below the desired peak level is generated with an iterative method or a maximum iteration is reached. The PAR reduction method cancels the high computation cost for accumulating the peak-canceling effort into each sample every iteration. In the i-th iteration, the method attempts to resolve an intermediate peak canceling signal that can reduce the i peaks of the resultant signal to the desired peak level. The method only calculates the samples of the intermediate peak canceling signal and performs balance testing in some locations where the peak level of the original signal is larger than a selected threshold.Type: GrantFiled: January 24, 2008Date of Patent: May 1, 2012Assignee: STMicroelectronics R&D Co.
