Abstract: An information processing method is executed by an information processing device that detects an attack against a monitored object by communicating with the monitored object. The information processing method includes: obtaining attack information related to an attack against the monitored object; and determining priorities of a plurality of detection rules based on the attack information, and storing the priorities in association with the plurality of detection rules, the plurality of detection rules being used for determining whether an anomaly has occurred in the monitored object when the monitored object is attacked. The priorities indicate at least one of (i) an order in which the plurality of detection rules are used or (ii) whether to use the plurality of detection rules when determining whether an anomaly has occurred in the monitored object.

Abstract: A transmitting array antenna includes a second antenna group placed in a position inside a first antenna group in a first direction and a position different from the first antenna group in a second direction. A receiving array antenna includes a fourth antenna placed in a position outside a third antenna group arranged in the first direction and a position different from the third antenna group in the second direction. An interelement spacing between a receiving antenna of the third antenna group located at an end on a second side is identical to an interelement spacing in the first direction between a transmitting antenna of the first antenna group on the first side and each of the second antenna group. In a case where the first antenna group and the third antenna group are identical in position in the second direction, positions of antennas are different.

Abstract: A wireless communication device includes a communication circuit for performing communication with a plurality of remote devices in a mode of central or peripheral and a processor. When the remote devices are connected to the communication circuit by communication of a same standard and a number of the remote devices is less than L+1, the processor accepts an acquisition request for the central from the remote devices and sets a role of the communication circuit with respect to the remote devices to the peripheral. When the remote devices are connected to the communication circuit by communication of the same standard and a number of the remote devices is L+1 or more, the processor rejects the acquisition request for the central from the remote devices and sets the role of the communication circuit with respect to the remote devices to the central.

Abstract: A display device includes an image light emitter, a light guide body, and a processor. The image light emitter emits image light beams of a left-eye image and a right-eye image. The light guide body has an emission surface from which light incident from the image light emitter is emitted. The processor is configured to control the image light emitter. The light guide body includes a holographic element, and a light guide portion enclosing the holographic element. The image light beams emitted from the image light emitter are incident on the holographic element. The processor is configured to: identify positions of both eyes of a user based on a captured image of an imager that captures both eyes of the user; and adjust positions where the image light beams are incident on the holographic element according to the positions of the both eyes of the user.

Abstract: A vehicle security system includes: a primary dynamic authenticator disposed in an integrated electronic control unit (ECU) in the vehicle; and one or more connection managers. In the vehicle security system, when an access request for access to an access destination in the vehicle is made by an access source in the vehicle, the primary dynamic authenticator dynamically performs authentication of the access request based on a state of the vehicle, and causes a connection manager located on a communication path between the access source and the access destination, among the one or more connection managers, to control a connection between the access source and the access destination, based on a result of the authentication of the access request.
