Abstract: A machine-implemented method for determining whether a to-be-analyzed software is a known malware or a variant of the known malware includes the steps of: (A) configuring a processor to execute the to-be-analyzed software, and obtain a to-be-analyzed system call sequence that corresponds to the to-be-analyzed software with reference to a plurality of system calls made in sequence as a result of executing the to-be-analyzed software; (B) configuring the processor to determine a degree of similarity between the to-be-analyzed system call sequence and a reference system call sequence that corresponds to the known malware; and (C) configuring the processor to determine that the to-be-analyzed software is neither the known malware nor a variant of the known malware when the degree of similarity determined in step (B) is not greater than a predefined similarity threshold value.

Abstract: An object is held in any one of a plurality of specific orientations to present an aspect, corresponding to a specific orientation, to an imaging module of an electronic device. An image of the aspect is captured. The current captured image is compared with images in a library of image-command associations to find a match. If a match is found, the electronic device triggers a command execution of the matching image-command association. If no match is found, a new image-command association is established and stored in the library of the image-command associations.

Abstract: A storage management system includes a storage unit with first and second partitions with consecutive physical addresses. The control unit manages the storage unit and has a measurement unit, arrangement unit, and reallocation unit. The arrangement unit arranges currently stored files in the two partitions. The measurement unit measures the file, the free space of the two partitions, a difference between the file size and the free space of the second partition, and determines whether the free space of the second partition is sufficient to store the file. The reallocation unit shares the free space from the first partition to the second partition.

Abstract: In a basal blood pressure measuring method, an examinee presses a basal blood pressure measuring key after the examinee gets out of bed in the morning to start a sphygmomanometer to measure the basal blood pressure A microprocessor in the sphygmomanometer displays the measured basal blood pressure and date on a display screen and saves the measured basal blood pressure into a basal blood pressure buffer of a memory automatically. When the examinee presses a basal blood pressure average key, the microprocessor in the sphygmomanometer computes and processes the basal blood pressure data in the memory and displays the basal blood pressure average of the current week or the past few weeks on the display screen to inform whether or not the examinee is a hypertension patient.
