    Abstract: A detection device includes a processor that detects a state change of a target object based on sensor value array data in which sensor values acquired from sensors are associated with array positions of the sensors, generates, with respect to two pieces of the sensor value array data for which the sensor values are acquired at different times, differential value array data, generates, from the differential value array data, two pieces of partial differential value array data, and determines presence or absence of a smooth change of the differential values in the differential value array data based on a result of threshold determination on similarity between the differential values in the two pieces of partial differential value array data and a result of threshold determination on a variance value of the differential value array data.

    Abstract: A communication device conforming with plural communication standards and having a storage storing a plurality of virtual stacks each having an application program and communication program that implements a protocol stack for communication by the application program. An executor executes the virtual stacks, and a switching controller switches the virtual stacks to be executed by performing a first processing in which at least one part of at least one of the virtual stacks is read from storage and stored into a memory of, and executed by, the executor. Then, in accordance with free capacity in the memory, at least one part of at least one of the virtual stacks executed in the first processing is deleted from memory. In a second processing at least one part of at least one of the virtual stacks is read from the storage and stored into the memory of, and executed by, the executor.

    Abstract: A data collection system includes a plurality of sensor modules each provided with a sensor unit, and a data collecting device. The data collecting device (200) is provided with: a clock output unit (201) which outputs a clock signal; an enable signal output unit (202) which outputs to a prescribed sensor module (100) an enable signal at intervals equal to or greater than the number of clock signals corresponding to the number of sensor modules (100); a counter (203) which counts the number of clock signals; and a sensor signal input unit (205) into which data output by the sensor modules (100) is input via a bus line, and which records said data in association with the count value. Using the clock signal as a trigger, each sensor module (100) functions as a shift register feeding the enable signal to the subsequent stage sensor module (100), and each sensor module (100) outputs output data from the sensor unit (110) in said sensor module (100) to the sensor signal input unit (205) only when the enable signal has been fed to said sensor module (100).
