Abstract: An adjustable collimator includes pairs of knobs configured to adjust an aperture size by manipulating one or both of the knobs. A pair of knobs configured to adjust different dimensions of the aperture may be disposed at opposite sides of the collimator. Another pair of knobs configured to adjust different dimensions of the aperture may be disposed on a same side of the collimator.

Abstract: A mobile radiography system includes sensors to detect a tilt angle and or pitch angle of the system to prevent deployment of the extendable boom and/or column and/or prevent activation of a motor drive if the tilt angle or pitch angle exceeds a pre-set boundary.

Abstract: An adjustable collimator includes a pair of knobs configured to adjust an aperture size by manipulating one or both of the knobs. The knobs may be disposed at opposite ends of a first shaft. The knobs may be configured to each adjust a same dimension of the aperture or to each adjust a different dimension of the aperture.

Abstract: A security risk management system comprises a vulnerability database, an asset database, a local threat intelligence database and a threat correlation module. The vulnerability database comprises data about security vulnerabilities of assets on a network gathered using active or passive vulnerability assessment techniques. The asset database comprises data concerning attributes of each asset. The threat correlation module receives threat intelligence alerts that identify attributes and vulnerabilities associated with security threats that affect classes of assets. The threat correlation module compares asset attributes and vulnerabilities with threat attributes and vulnerabilities and displays a list of assets that are affected by a particular threat. The list can be sorted according to a calculated risk score, allowing an administrator to prioritize preventive action and respond first to threats that affect higher risk assets.
