Abstract: A traffic-volume estimation device includes a communication unit that communicates with a plurality of probe vehicles; a storage unit that accumulates probe information pertaining to the plurality of probe vehicles; and a processing unit that performs traffic-volume estimation processing for obtaining an estimate for the traffic volume of vehicles on a feeder road connected to a first target location in a road network. The traffic-volume estimation processing includes: a first process for obtaining, on the basis of the probe information, movement information that includes a time, that was needed for the probe vehicle positioned at a second target location on the feeder road to pass by the first target location, and the distance from the second target location to the first target location; and a second process for obtaining the estimate by referring to a traffic-volume estimation table that is updated on the basis of satellite data.

Abstract: Provided is a shopping cart capable of simplifying equipment of a storage area of the shopping cart. A shopping cart allowed to be nested in a front-rear direction, including: a cart body; a battery configured to supply power to an electronic device attached to the cart body for displaying commodity information read by a reading device; a power receiving portion provided on a front side of the cart body and configured to be electrically connectable to an external power supply; and a power transmitting portion provided on a rear surface side of the power receiving portion and configured to supply power to a power receiving portion of another shopping cart nested in the shopping cart. Each of the power receiving portion and the power transmitting portion is provided with a magnet configured for holding a relative position.

Abstract: A charging assistance system includes a processor configured to execute a generation process of generating charging plan data for a vehicle on the basis of: predicted power consumption of the vehicle calculated on the basis of a future traveling schedule of the vehicle; and a charging condition at each predicted stop place based on the traveling schedule.

Abstract: An image compression device includes an extraction unit configured to extract a protection target region from an image, the protection target region being a region including a protection target of personal information; and a compression unit configured to compress the image by compressing the protection target region at a compression ratio higher than a compression ratio for a region other than the protection target region in the image.

Abstract: A state estimation apparatus includes a first acquisition unit configured to acquire a measurement result of a first sensor, the first sensor being a sensor mounted in a vehicle in which a worker is to ride and being configured to measure a state of the vehicle, a second acquisition unit configured to acquire a measurement result of a second sensor, the second sensor being a sensor carried by the worker and being configured to measure a state of the worker, and an estimation unit configured to estimate, based on the measurement result of the first sensor and the measurement result of the second sensor, a state related to work of the worker.

Abstract: A display method is for displaying a delivery status of a related package on a terminal device used by a user, the related package being a package related to the user.

Abstract: A time determining device includes a plan information acquiring unit configured to acquire plan information indicating a scheduled standby time and a scheduled work time of a worker in a predetermined area, a travel record information acquiring unit configured to acquire travel record information including a travel position and a travel time of a vehicle in which the worker rides, and a time determining unit configured to determine, based on the plan information and the travel record information, a standby record time and a work record time of the worker in the predetermined area.
