Abstract: Sensing systems and methods for sensing a stationary individual. A sensing system may use a first sensor to determine whether a detected thermal signature is associated with a human presence within a space.

Abstract: The present invention discloses a cage-type CT scanner. The present invention involves reducing the rotation arc of the rotating member and the vibration amplitude of the whole machine by means of reducing the volume and weight of the CT scanner, without reducing the vibration of the CT scanner itself by eliminating eccentric force in transmission via balance correction or by any other means. Moreover, in the present invention, no crawler that realizes mechanical driving is used so as to decrease the parts in the motor's synchronization structure. Such efforts help reduce costs and allow the CT scanner to be suitable for more applications.
