In example implementations, a method is provided. The method includes determining, by a processor, that a vehicle is approaching a door of a building based on a velocity vector of the vehicle, calculating, by the processor, a time of arrival of the vehicle at the door based on the velocity vector of the vehicle and a distance of the vehicle from the door, and controlling, by the processor, the door to begin opening at a time based on the time of arrival and an amount of time for the door to open such that the door is opened when the vehicle arrives at the door.

A gate apparatus includes a gate unit which is disposed on a second plane crossing a first plane in which an authentication object moves in one direction and which partitions a moving space of the authentication object from another space, an inclined face which is formed on the gate unit to cross the first plane and the second plane and which is inclined upwardly from the first plane, a display configured to display an image on the inclined face, and an image acquisition unit configured to capture an image of the authentication object in proximity to the display.

A gate apparatus includes a pair of gate units which are distanced from each other with an interval of width of a passage area allowing a moving body to bidirectionally pass therethrough along a vertical plane on a horizontal plane. The gate units are each equipped with a first flapper gate in a first direction and a second flapper gate in a second direction. One gate unit is equipped with a first imaging means to capture a first image of the moving body in the first direction while another gate unit is equipped with a second imaging means to capture a second image of the moving body in the second direction. The first flapper gate and the second flapper gate are controlled to open or close the passage area based on at least one of the first image and the second image.

A system for controlling access to an access-restricted zone in a building includes a transmitting device transmitting a first radio signal, a receiving device for radio signals, a control device and a signal processing device communicatively connected to the receiving and control devices. The signal processing device determines a first channel impulse response based on the first radio signal received by the receiving device and a second channel impulse response based on a second radio signal received by the receiving device. The second radio signal is transmitted from a first mobile electronic device of a first user. The signal processing device determines a degree of similarity by evaluating the first and second channel impulse responses. The degree of similarity indicates how similar the first and second channel impulse responses are to one another. The control device initiates a building action if the degree of similarity meets a specified rule.

A component includes a housing mounted at an entry point of an enclosure protecting a machine. The component includes a first RFID sensor, in the housing, that reads a first RFID tag in close proximity to the first RFID sensor indicating a closed status of a movable barrier of the enclosure at the entry point. Opening of the movable barrier allows entry to the enclosure. The component includes a second RFID sensor, in the housing, that reads a second RFID tag of an authorized person. The component includes a barrier access module that sends an open alert that the movable barrier is in an open state in response to the first RFID sensor not being close enough to read the first RFID tag, and an identification module that sends tag information unique to a person from the second RFID tag.

A processing system may obtain traveler data comprising location data of devices of a plurality of travelers, the travelers having reservations to travel aboard a vehicle of a transportation service provider from a point of departure at a designated time of readiness and obtain timing data of a queue from a service provider system associated with the queue, where at least one traveler of the travelers is to traverse the queue to arrive at the point of departure. The processing system may then calculate arrival times of the travelers based upon the traveler data and based upon the timing data of the queue, determine that an arrival time of the at least one traveler is after the designated time of readiness, and perform at least one remedial action in response to the determining that the arrival time of the at least one traveler is after the designated time of readiness.
