A pedestrian navigation and spatial relation device including a position finder, a spatial relationship sensor, an input mechanism, and an output mechanism. The position finder can be configured to determine a geographic position of the device based upon received wireless signals. The spatial relationship sensor can provide data used to detect a position of at least one obstacle relative to the device. The input mechanism can specify a destination location. The output mechanism can present device output to a user. The device output can include sensory indicators for at least one of guiding a pedestrian to the destination location and warning a pedestrian about the detected obstacles.

Collision avoidance systems and methods are implemented on unmanned mobile vehicles to supplement map-based trajectories generated by the vehicles' navigation systems. These systems include radar, which detect obstacles in the path of the unmanned mobile vehicles, and collision avoidance modules, which enable the vehicles to avoid unexpected obstacles by adjusting their trajectories and velocities based on feedback received from the radar. In general, when an obstacle is detected by the radar, the collision avoidance module modifies the commanded velocity of an unmanned mobile vehicle by subtracting from the nominal commanded velocity the component that is in the direction of the obstacle. The magnitude of the velocity modification typically increases as the distance between the mobile vehicle and the obstacle decreases.

A small, reusable interceptor unmanned air vehicle (UAV), an avionics control system for the UAV, a design method for the UAV and a method for controlling the UAV, for interdiction of small scale air, water and ground threats. The UAV includes a high performance airframe with integrated weapon and avionics platforms. Design of the UAV first involves the selection of a suitable weapon, then the design of the interceptor airframe to achieve weapon aiming via airframe maneuvering. The UAV utilizes an avionics control system that is vehicle-centric and, as such, provides for a high degree of autonomous control of the UAV. A situational awareness processor has access to a suite of disparate sensors that provide data for intelligently (autonomously) carrying out various mission scenarios. A flight control processor operationally integrated with the situational awareness processor includes a pilot controller and an autopilot controller for flying and maneuvering the UAV.

A communication system architecture (SA) for a vehicle which may be integrated into the vehicle's multiplexed electronic component communication system, and a process for communicating with the vehicle to provide information for and about the vehicle's operational status and coordinating the vehicle's activities. The communication system will include a multi-functional antenna system for the vehicle that will have the capability to receive AM / FM radio and television signals, and transmit and receive citizens band (CB) radio signals, satellite and microwave and cellular phone communications. The antenna may be installed as original equipment or as a back-fit part in the after-market. In either case the multi-functional antenna will be integrated with the vehicle's multiplexed electronic component communication system. The process for communicating with the vehicle will involve a communication service for which the vehicle's driver will enroll for and service will continue so long as maintenance fees are paid. The service will be capable of providing various levels of information transfer and coordination. The levels may include vehicle information such as (1) the need for servicing and location of the nearest service center with the necessary parts in stock, (2) routing, and (3) load brokering and coordination. The modular design of the system architecture (SA) will allow it to be employed with the vehicle platform that does not possess a full multiplexed electronic component communications system. The resulting vehicle, using an after-market application package, will be able to participate in some of the services.

An apparatus includes an upstream transport surface TSa which, while facing a circumferential surface DS of a developing roller 33, is disposed upstream of an area (developing area) in the vicinity of a latent image forming surface LS, and a downstream transport surface TSb which, while facing the circumferential surface, is disposed downstream of the developing area. The apparatus forms electric fields on the upstream and downstream transport surfaces for moving a charged developer T from an upstream side toward a downstream side. In the apparatus, the transport speed of developer on the upstream transport surface is higher than that on the downstream transport surface. As a result, there can be lowered a speed at which the developer which has not adhered to the circumferential surface and has reached a downstream end portion of the upstream transport surface flies out toward the vicinity of the developing area. Also, there can be avoided a problem in that the developer stagnates at an upstream end portion of the downstream transport surface with a resultant hindrance to collection of the developer.

A vehicle's drag-reducing apparatus, adapted to be arranged at the tail end of a vehicle, includes a diversion body positioned at the lateral surface of the vehicle and a rotary piece. The airflow flowing across the lateral surface of the vehicle body is guided to the tail end of the vehicle by the diversion body. One end of the rotary piece is pivoted to the vehicle body, while another end is fixed to the diversion body. Rotating the rotary piece will bring along the diversion body to be abutted against the tail end of the vehicle body or to be moved to the position far away from the tail end of the vehicle body. Thereby, the opening of the rear door at the tail end of the vehicle won't be hindered, even where there is an arrangement of the diversion body.
