Abstract: Discloses are systems, methods and computer readable mediums for automated verifications of potential vulnerabilities of one or more sites or code utilizing one or more neural networks. The systems, methods and computer readable mediums can transmit one or more scan operations to one or more sites, receive one or more responses to the one or more scan operations, tokenize the one or more responses, transmit to one or more neural networks the one or more tokenized responses, receive from the one or more neural networks verification of the one or more tokenized responses, and determine one or more confidences of the one or more verified responses.

Abstract: A mounting head, a system incorporating the mounting head and a support such as a monopod, and a system including the mounting head, the monopod, and a camera enable a photographer to tilt a monopod or other camera support while maintaining a substantially level horizon of an image. An upper head assembly and a lower head assembly are connectable to the camera and the monopod respectively. The assemblies are interconnected by a universal joint which allows the upper assembly to remain level as roll and pitch vary. A resilient member dampens relative motion of the head assemblies. As a photographer moves the camera to capture a scene, force is transmitted from the photographer's hands via the mounting head through the monopod. The photographer maintains a level horizon as the monopod tilts. A test apparatus enables design of a resilient member for desired interaction with selected classes of equipment.
