  • Publication number: 20220146674
    Abstract: Generation unit generates a plurality of transmission pulses, the plurality of transmission pulses being formed so that phases in a plurality of respective regions of the transmission pulse can be different from each other, and being formed so that a phase difference between the phases in the plurality of respective regions of the transmission pulse is changed according to a transmission order of the transmission pulses. Transmission unit repeatedly transmits the generated transmission pulses. Receiving unit receives reflected pulses of the transmission pulses reflected on a distance-measurement-target object. Detection unit detects a phase difference between phases in a plurality of respective regions of the received reflected pulse. Distance calculation unit calculates a distance to the distance-measurement-target object based on a receiving timing of the received reflected pulse and a transmitting timing of the transmission pulse corresponding to the phase difference detected from the reflected pulse.

  • Publication number: 20220147617
    Abstract: An information processing apparatus includes an analysis unit, a storage unit, and a verification unit. The analysis unit analyzes a program before it is executed and extracts a branch in the program. The analysis unit acquires branch information regarding the branch and program part information regarding the part of the program that may be executed from a branch destination of the branch to a next branch part. The storage unit stores the branch information, the program part information, and a first eigenvalue acquired in advance for the program part regarding the program part information. When the program is executed and an execution part reaches the branch, the verification unit acquires a second eigenvalue for the program part. The verification unit determines whether or not the second eigenvalue matches the first eigenvalue, thereby verifying integrity of the program part.
