A plurality of switch elements is configured to turn on/off reading-out of a signal from a conversion element. A signal line extends in a column direction and is configured to be used for reading a signal from a conversion element. A drive line extends in a row direction and is connected to a switch element. A drive circuit is configured to supply a signal for turning-on/off a switch element. The drive line is shared between adjacent rows. The drive circuit switches a scanning direction between a case where signals from the plurality of conversion elements are read out individually and a case where signals from two or more conversion elements of the plurality of conversion elements are added and read out.

An apparatus for measuring photon information and a photon measurement device are disclosed. The apparatus comprises a signal conversion module for converting an initial signal outputted by the photoelectric sensor into a converted signal in a voltage form, an integral comparison module for integrating a difference between the initial signal and a feedback signal from the negative feedback module and generating a comparison signal based on a magnitude relationship between a reference level and a combination result of an integral signal and the converted signal, wherein the integral signal is a signal for representing an integral of the difference between the initial signal and the feedback signal, a transmission control module for controlling the comparison signal to be transmit based on a clock signal to output a digital signal, a negative feedback module for converting the digital signal into the feedback signal and feeding the feedback signal back to the integral comparison module, and a measurement module for determining, based on the comparison signal and/or the digital signal, an arrival time of a high-energy photon detected by the photoelectric sensor. The apparatus and the device require few circuit components, and can realize high-precision time measurement.

Systems and methods are described for securely monitoring a shipping container for an environmental anomaly using elements of a wireless node network of sensor-based ID nodes disposed within the container and a command node associated with the container. The method has the command node identifying which of the ID nodes are confirmed as trusted sensors based upon a security credential specific to each of the ID nodes; monitoring only the confirmed ID nodes for sensor data broadcast those ID nodes; detecting the anomaly based upon the sensor data from at least one of the confirmed ID nodes; automatically generating an alert notification related to the detected environmental anomaly for the shipping container; and transmitting the alert notification to the external transceiver to initiate a mediation response related to the detected environmental anomaly.
