Patent number: 8558180Abstract: Among other things, one or more systems and/or techniques for integrating electrical charge yielded from an indirect conversion detector array of a pulsating radiation system are provided. The integration begins during a resting period between a first and second pulse and ends before the second pulse is emitted. Electrical charge that is measured during a resting period is integrated, while electrical charge measured during a pulse is not integrated. In this way, parasitic contributions caused by the direct interaction of radiation photons with a photodiode are reduced and a quantum efficiency of the indirect conversion detector array is increased, for example. Moreover, the period of integration can be adjusted such that a voltage gain related to the indirect conversion detector array can be varied to a predetermined level.Type: GrantFiled: September 2, 2010Date of Patent: October 15, 2013Assignee: Analogic CorporationInventors: Ruvin Deych, Charles Shaughnessy

Publication number: 20130259202Abstract: Among other things, one or more techniques and/or systems are described herein for transferring communication information between a stationary unit and a movable (e.g., rotating) unit, or between two movable units without contact between the units. A transmitter is configured to translate digital information into an analog signal which may be fed to an input coupler positioned within a channel of an electrically conductive member (e.g., on a first unit, such as a stationary unit). The current of the signal induces a signal in an output coupler (e.g., on a second unit, such as a movable unit). Voltage characteristics of the induced signal (e.g., which substantially correspond to voltage characteristics of the signal fed into the input coupler) may subsequently be used to reconstruct the digital data at a receiver. In this manner, information can be communicated between two non-contacting units.Type: ApplicationFiled: March 30, 2012Publication date: October 3, 2013Applicant: Analogic CorporationInventors: Michael Sloutsky, Hans J.
