Abstract: A drive system for a rotorcraft includes first and second gearbox assemblies and a lubrication assembly. The lubrication assembly includes first and second lubrication systems and a valve connected between the first and second lubrication systems such that when the valve is in a first position, a test mode of operation of the lubrication assembly is enabled and when the valve is in a second position, a normal mode of operation of the lubrication assembly is enabled. The lubrication assembly also includes a valve control unit operable to instruct the valve to selectively move between the first position and the second position.

Abstract: According to one aspect of the present disclosure, a system comprises a processor configured to execute instructions that cause operations to, in response to automatic shuffling of a set of cards by a shuffler, detect a first anomaly associated with a first card of high value that was used during a round of play for a first card game in which a first player participated at a gaming table. The processor is further configured to execute instructions that cause operations to, in response to analysis by the processor of shuffler data, detect a relationship between the first anomaly and a second anomaly. The second anomaly is associated with a second card of high value that was used during a round of play for a second card game in which a second player participated.

Abstract: A vascular monitoring system includes a collar configured to be positioned about a patient's vessel and a transducer coupled to the collar. The collar may be formed by a strap that is wrapped around the patient's vessel and maintained in a closed configuration. The transducer is configured to emit an ultrasonic signal that is transmitted through the patient's vessel.

Abstract: Apparatus, systems, and methods may operate to receive operational power from a primary power supply at a processor housed within a wagering game machine, where the processor is operable to present a wagering game. Further activities may include determining that the wagering game machine is currently in a hibernation state, authenticating at least one hibernation file, and resuming operation of the wagering game machine to a base operation state defined by the at least one hibernation file. Additional apparatus, systems, and methods are disclosed.

Abstract: A system and method for providing security services to an electronic gaming machine (EGM) utilizes system management interrupts (SMIs) triggered by security events to invoke execution by the EGM processor of one or more SMI handlers configured to provide a security service. Security events include the opening of an access panel on the EGM, an AC power loss to the EGM, a request for security attestation, a request for a secure encryption key, and other events requiring a secure operation to be carried out.
