Abstract: A latency analysis system determines a latency period, such as a wait time, at a user destination. To determine the latency period, the latency analysis system receives location history from multiple user devices. With the location histories, the latency analysis system identifies points-of-interest that users have visited and determines the amount of time the user devices were at a point-of-interest. For example, the latency analysis system determines when a user device entered and exited a point-of-interest. Based on the elapsed time between entry and exit, the latency analysis system determines how long the user device was inside the point-of-interest. By averaging elapsed times for multiple user devices, the latency analysis system determines a latency period for the point-of-interest. The latency analysis system then uses the latency period to provide latency-based recommendations to a user. For example, the latency analysis system may determine a shopping route for a user.

Abstract: A system and method of tracking an object is disclosed.

The determined direction is used to orient the optical axis of the lens toward object to track the object. The photodetector array and lens may be coupled to a projectile and the determined direction may be used to direct the projectile to hit a target.

Abstract: While a user carrying a mobile terminal is aboard a vehicle, communication is available between on-vehicle equipment and the mobile terminal by near field communication, and therefore, the mobile terminal stands by and only the location information measured by the on-vehicle equipment is transmitted to a server. After the user gets off the vehicle, radio communication between the on-vehicle equipment and the mobile terminal is cut off, and therefore, the mobile terminal starts measuring the location etc. and only the location information measured by the mobile terminal is transmitted to the server. The server accumulates the location information sent from the on-vehicle equipment or the mobile terminal. Then, the server generates an inquiry image in which figures each representing the movement trajectory of the user are combined on a map based on the accumulated location information and transmits the inquiry image to the on-vehicle equipment.

Abstract: A system and method for more accurately and robustly determining the heading of a vehicle by taking measurements of angle rates using rate sensors mounted on a movable mechanical assembly. In a quasi-static state of the vehicle, the mechanical assembly is rotated around axes perpendicular to the tangent plane of the Earth, and angle rates are measured by the rate sensors at different rotational angles of the mechanical assembly. The measurements of the angle rates are then computed to determine the initial heading of the vehicle relative to the true north of the Earth in the quasi-static state of the vehicle. After determining the initial heading, navigation state propagation is performed to determine the heading of the vehicle in non-quasi-static state of the vehicle. By taking measurements of the rate sensors at different rotation angles and performing computation, the heading of the vehicle relative to the Earth's true north can be determined using less accurate angle sensors.
