Abstract: An antenna includes an antenna body and a housing case. The antenna body configured to enter a first mode exhibiting an artificial magnetic conductor character with respect to an electromagnetic wave in a first frequency band and configured to enter in a second mode (TM mode) serving as a resonator for the electromagnetic wave in a second frequency band higher than the first frequency band. The housing case includes a bottom plate on which the antenna body is installed and a side wall provided standing from the bottom plate and spaced with a distance from a periphery of the antenna body. The housing case is a case made of metal including an opening in a face through which the electromagnetic wave enters and exits.

Abstract: An antenna according to an aspect includes an antenna body configured to radiate an electromagnetic wave when entering a first mode exhibiting an artificial magnetic conductor character with respect to an electromagnetic wave in a first frequency band and entering a second mode serving as a resonator for the electromagnetic wave in a second frequency band higher than the first frequency band and a package receiving box (case) configured to support the antenna body and to be placed on a placement surface directly or via a placement member. The antenna body is supported by the package receiving box with a direction of an electrical current in the first mode being parallel to the placement surface.

Abstract: A hydraulic system for a vehicle includes a hydraulic monitoring control unit configured to receive an operational signal from a sub-system of the vehicle and control flow of hydraulic fluid to actuators of components based on the operational signal. The hydraulic monitoring control unit is configured to bypass the flow of the hydraulic fluid in relation to a subset of the actuators in response to the operational signal indicating an altered operational state of the sub-system.

Abstract: A system and method of controlling a position of a structure. A position command indicating a desired position for the structure and a position feedback signal indicating the position of the structure are received. A position control signal is generated based on a difference between the desired position and the position indicated by the position feedback signal. A stop feedback signal relative to the position of the structure is received. A stop control signal is generated based on the stop feedback signal and a stop condition for the structure. One of the position control signal and the stop control signal is selected. The selected one of the position control signal and the stop control signal is provided to an actuator for controlling the position of the structure.

Abstract: A server capable of connecting in a wired or wireless manner to a storage apparatus that stores a package delivered to a recipient, and an other electronic device, includes a communication unit, a storage unit, and a controller. The communication unit communicates with the storage apparatus and the other electronic device. The storage unit stores first information indicating a home probability of the recipient of the package. The controller controls the communication unit such that the first information stored in the storage unit and second information that is acquired from the storage apparatus and that indicates an availability of the storage apparatus are sent to the other electronic device in response to a request from the other electronic device, received by the communication unit.

Abstract: A system includes a server, a company terminal for use by a delivery company, a recipient terminal for use by a recipient of a package, and a storage device including a container to store the package. When the storage device is selected, by the delivery company on the company terminal, to reserve the container, the delivery terminal transmits a request to reserve the container to the server. When the storage device receives the request from the server, the storage device reserves the container and transmits a notification indicating that the container is reserved to the server. When the server receives the notification, the server transmits information indicating that the container is reserved to the recipient terminal. When the recipient terminal receives the information indicating that the container is reserved from the server, the recipient terminal displays the information indicating that the container is reserved on the recipient terminal.

Abstract: A method and system for managing a control system having triple redundancy for an aircraft. The method comprises receiving a group of messages from a transmitting lane in a controller including three lanes in which a first lane failure has previously occurred. The method identifies an activity indicator, a status generated by each lane in a group of lanes, and a cyclic redundancy check value generated by each lane in the group of lanes in the group of messages. The cyclic redundancy check value generated by a lane in the group of lanes is generated using a key assigned to the lane. The method disables the controller when at least one of an anomaly is indicated in the status, an activity indicator mismatch is present, or a cyclic redundancy check value mismatch is present in the group of messages that indicates a second lane failure has occurred.

Abstract: The electronic device includes a temperature sensor and a controller. The controller acquires temperature detected by the temperature sensor when transitioning to the predetermined mode. When the temperature is equal to or higher than a temperature judgment value, the controller performs a plurality of functions corresponding to the predetermined mode. When the temperature is lower than the temperature judgment value, the controller performs a subset of the plurality of functions.

Abstract: A system and methods for redundant current-sum feedback control of an actuator system is presented. An actuator comprises actuation coils configured to actuate the actuator, and an actuation coil current sensor senses a measured total coil current comprising a sum of coil currents of each of the actuation coils. Actuator coil controllers control the actuation coils based on a commanded total coil current and the measured total coil current.

Abstract: An apparatus and method for controlling an actuator. A plurality of commands for the actuator are received from a number of primary controllers by a command lane and a monitor lane. The command lane selects a first selected number of commands from the plurality of commands using a selection rule. The monitor lane selects a second selected number of commands from the plurality of commands using the selection rule and generates a check value for the second selected number of commands. The first selected number of commands from the command lane and the check value from the monitor lane are combined to form an actuator control command message comprising the first selected number of commands and the check value. The actuator control command message is sent to an actuator controller for controlling the actuator.
