Abstract: An example method includes receiving electrical power via a physical connector of a mobile computing device; determining, by a controller of the mobile computing device, a value of a temperature of a virtual temperature sensor, the value representing a difference between a temperature measured by a first temperature sensor of a plurality of temperature sensors of the mobile computing device and a temperature measured by a second temperature sensor of the plurality of temperature sensors, wherein a distance between the first temperature sensor and the physical connector is less than a distance between the second temperature sensor and the physical connector; determining, based on the value of the temperature of the virtual temperature sensor, whether an overheat event has occurred; and responsive to determining that the overheat event has occurred, reducing an amount of electrical current flowing through the physical connector.

Abstract: A method is described. A total number of traps to be filled in a detector of an imaging system is estimated based on a measured signal sensed by the detector. The measured signal is adjusted based on the estimated total number of traps and a current trap state of the detector. The trap state of the detector is subsequently updated.

Abstract: A method and system for implementing the method for extending the effective field of view of a CT scanner, comprising the steps of forming a preliminary estimate of the projection mass for each image projection, forming a preliminary estimate of the center of mass for each image projection, estimating the image mass and center of mass from the preliminary projection mass and center of mass projections, and forming a second estimate of the projection mass and center of mass from the image mass and center of mass.
