Abstract: A ceiling fan or ceiling fan includes a body defining an interior passage having an inlet and an outlet provided on the body. The inlet, outlet, and interior passage can be annular. An impeller is mounted within the interior passage and driven by a motor mounted within the body to draw a volume of air through the interior passage from the inlet to the outlet. A movable deflector including an inner angled surface and a lower angled surface is provided at the outlet to direct the airflow in a generally outward or generally downward direction, respectively.

Abstract: An anti-malware system monitors the emulation of a suspicious program in a sandbox environment. The anti-malware system determines that the suspicious program is attempting to access a restricted area of memory (e.g., an executable instruction in the restricted area). Rather than stop the emulation, the anti-malware system can temporarily pause the emulation of the suspicious program. During this pause, the anti-malware system can determine whether the suspicious program is containable within the sandbox environment. If the anti-malware system determines that the emulation of the executable instruction is safe (e.g., that the program is containable), the anti-malware system will resume emulation. If the anti-malware system determines that the emulation of the executable instruction is not safe, the anti-malware system may shut down emulation.

Abstract: An anti-malware application can emulate a suspicious program in a sandbox environment and retrieve any exception handlers the suspicious program attempts to register with the operation system. When the suspicious program triggers an exception, the anti-malware application can save a current context of the suspicious program being emulated. To emulate the handling of the exception, the anti-malware application can validate an exception handler chain including one or more exception handlers added by the suspicious program. The anti-malware application can then select and emulate an exception handler based on the saved context of the suspicious program at the time the exception was triggered. If the first exception handler is successful at resolving the exception, the anti-malware application can then save an updated post-exception context and continue emulation of the suspicious program based on the result of the first exception handler.

Abstract: A method that automatically generates blacklists for a sandbox application. The method first obtains a set of disassembled operating system (OS) dynamic-link libraries (DLLs) and then identifies application programming interfaces (API) functions that have respective kernel interruptions. The identified API functions that have kernel instructions are saved to an interrupt list. Based on the interrupt list, a processor generates a blacklist that includes for each of the DLLs, the identified API functions in the interrupt list, all API functions that directly or indirectly invoke one of the identified API functions in the interrupt list via one or more nested API functions. The method outputs the blacklist to the sandbox application that operates on a sample file to emulate API functions of the sample file that match the blacklist. All other APIs not identified as being blacklisted, are then considered whitelisted and are allowed to run natively.

Abstract: A computer-implemented security system and method provides signature pathway authentication and identification. The system and method include establishing a user-defined cognitive signature pathway through multiple graphical zones of a graphical user interface. The signature pathway enables authorized user access to an otherwise secured location. Subsequent entries of the signature pathway entered via the graphical user interface are then validated. For all valid entries of the signature pathway, user access is allowed to the secured location.

Abstract: A steering assist system (SAS) for a cart is provided. The SAS may include an activation mechanism, a first actuation mechanism, a first support mechanism, a first linkage mechanism, a first stopping mechanism, and a first engagement mechanism. The first stopping mechanism may be configured to abut the first engagement mechanism to impede or prevent rotational movement of at least one wheel of the cart. The first actuation mechanism may be connected to the first linkage mechanism and the first linkage mechanism may be connected to the first stopping mechanism. The activation mechanism may be configured to activate the first actuation mechanism, causing the first linkage mechanism and the first stopping mechanism to move. The first stopping mechanism may be configured to move between a fully activated position and a fully deactivated position.
