Patent number: 9791395Abstract: The present disclosure provides a method for detecting thermal sealing defects of a container during its transportation along a process line. The method is particularly suitable for containers caped with a cap liner and sealed with an inner seal. The method makes use of a high frequency heat (e.g. by a high frequency heat induction unit) to cause eddy current in the inner seal after which there is sensing by an IR imager of radiation emitted from the conductive innerseal to generate sensed IR image data indicative of the sensed radiation. The sensing is characterized by at least one of (i) a time window of a sensing session of between 50 msec to 300 msec during which said container is being transported through the FOV; and (ii) a sensing range of a wavelength spectrum region from 2 ?m to 6 ?m. The IR data is then processed so as to generate output data indicative of the presence or absence of at least one defect in the sealing of the container by said innerseal.Type: GrantFiled: May 1, 2014Date of Patent: October 17, 2017Assignee: D.I.R.

Patent number: 9768737Abstract: In a preamplifier (amplifier) for the radiation detector, an interconnection layer connected to the bonding pad forms one electrode of a feedback capacitor. Since there is no wiring for connecting the bonding pad and capacitor, a parasitic capacitance caused by the wiring will not be generated. Moreover, the capacitor is arranged below the bonding pad with a conductive layer serving as the other electrode, so that the feedback capacitance of the capacitor is included in the parasitic capacitance between the interconnection layer and the substrate. Compared to the conventional case, an amount of capacitance corresponding to the parasitic capacitance caused by wiring and the feedback capacitance for the capacitor is reduced from the input capacitance. Thus, the input capacitance for the amplifying circuit is reduced.Type: GrantFiled: July 31, 2013Date of Patent: September 19, 2017Assignees: HORIBA, LTD., POLITECNICO DI MILANOInventors: Carlo Fiorini, Luca Bombelli

Patent number: 9753156Abstract: The invention relates to a detector (6) for detecting radiation, especially x-ray radiation used in a computed tomography system. The detector comprises a direct conversion material (9) for converting radiation into electrons and holes, which are used for generating an electrical detection signal.
