Abstract: Conventional email filtering services are not suitable for recognizing sophisticated malicious emails, and therefore may allow sophisticated malicious emails to reach inboxes by mistake. Introduced here are threat detection platforms designed to take an integrative approach to detecting security threats. For example, after receiving input indicative of an approval from an individual to access past email received by employees of an enterprise, a threat detection platform can download past emails to build a machine learning (ML) model that understands the norms of communication with internal contacts (e.g., other employees) and/or external contacts (e.g., vendors). By applying the ML model to incoming email, the threat detection platform can identify security threats in real time in a targeted manner.

Abstract: A sound box for floor-standing string instrument includes a resonance box being provided on a top surface with at least one recess for receiving a spike below the string instrument therein, and an opening extended through the top surface of the resonance box; and a pad attached to a bottom surface of the resonance box. The resonance box and the pad together form a sound reflection controlling mechanism, so that vibration waves transmitted from the string instrument to the sound box are reflected back to the string instrument. The reflected sound waves combine with the original vibration waves to amplify the sound produced by the string instrument, making the sound more brilliant and sweeter.

Abstract: The present invention provides a screwless fixing apparatus of the disk drive for quickly assembling and disassembling the disk drive without screws or other tools. When assembling the disk drive to the computer case, operate the screwless fixing apparatus of the present invention in open state. After the disk drive is in position, operate the controller components of the screwless fixing apparatus in close state and the disk drive can be fixed efficiently. When disassembling the disk drive, operate the controller components of the screwless fixing apparatus in open state, and the disk drive can be removed very simply.

Abstract: A shoulder rest for violin or the like capable of improving tone quality includes at least an elongated base and binding elements provided at two upper outer ends of the elongated base for fixing the latter to a back of a violin or the like. The elongated base is provided with a plurality of spaced and differently sized through holes corresponding to a plurality of bass and treble strings provided at a top of the violin or the like, and can therefore resonate with the strings to make the musical sound produced by playing the violin or the like even more sonorous and sweeter.

Abstract: The present invention provides a mobile fan-fixing device. Since the fan-fixing device of the present invention is designed to be mobile, it is unnecessary to disassemble the fan base with tools when assembling the motherboard and other electric products. In addition, because the fan is assembled by means of engaging with the fan-fixing base, it is no need to use tools when assembling, disassembling and replacing the fan. Moreover, the fan filter is assembled outside of the fan by means of engaging so that the filter is able to avoid the dust to the internal part of the fan and be cleaned without tools. Actually, it only needs taking the filter out and cleaning, then put it back.

Abstract: There is provided a computer case furnished with a multimedia playing device and integrally formed with the multimedia playing device on the top surface of the computer case, for accessing a multimedia medium in a safe way.
