A telerobot is designed for facilitating interaction between a remote user who is controlling the telerobot and a local user who is co-located with the telerobot. It comprises two wheels whose axes are aligned horizontally. It is designed to have its center of gravity located between the bottom of its body and the axes of its wheels so that it can stand up when powered or unpowered and can recover automatically after being toppled by an external force. Its camera's viewing angle can be adjusted to compensate for the swaying of its body due to inertia when it moves so that the remote user has a pleasant viewing experience. It supports gesture control text input so that the local user may input data into the telerobot without touching it. A virtual keyboard displayed on its screen has a layout optimized for gesture control text input.

The embodiment of the invention discloses a vehicle lane-changing control method and device. The vehicle lane-changing control method comprises the steps that an autonomous vehicle is controlled to bedriven into an adjacent to-be-shifted-in lane by utilizing a first control rule; the positional relationship between the autonomous vehicle and a reference lane line is obtained in real time, and thereference lane line is located between the autonomous vehicle and the to-be-shifted-in lane; whether the positional relationship meets a preset switching rule or not is judged; and when the positional relationship meets the preset switching rule, the autonomous vehicle is controlled to move by utilizing a second control rule corresponding to the preset switching rule. According to the vehicle lane-changing control method and device, practical lane-changing control of the autonomous vehicle is combined with postures, in lanes and between the lanes, of the autonomous vehicle, no complex controlalgorithm is needed, that is, steering control in the lane-changing process can accord with practical road conditions, and a lane-changing result which is more suitable for practical situations and more accurate is obtained.

A preceding vehicle recognition apparatus detects positions of two reflectors provided on a preceding vehicle from individual received signals each representing a signal reflected by the reflectors. The apparatus further detects position of an area of rear face of the preceding vehicle by integrating a plurality of received signals each representing a signal reflected by the body of the preceding vehicle. Thus, even when only one of the two reflectors is detected or both reflectors cannot be detected, the width of the preceding vehicle can be found. By using the width of the preceding vehicle, it is possible to keep track of the movement of the same preceding vehicle with a high degree of reliability.

The present invention systems and methods enable configuration of functional components in integrated circuits. A present invention system and method can flexibly change the operational characteristics of functional components in an integrated circuit die based upon a variety of factors. In one embodiment, manufacturing yields, compatibility characteristics, performance requirements, and system health (e.g., the number of components operating properly) are factored into changes to the operational characteristics of functional components. In one exemplary implementation, the changes to operational characteristics of a functional component are coordinated with changes to other functional components. Workflow scheduling and distribution is also adjusted based upon the changes to the operational characteristics of the functional components. For example, a functional component configuration controller changes the operational characteristics settings and provides an indication to a workflow distribution component. The workflow distribution component changes the workflow schedule based upon the operational characteristics settings (e.g., work flow is diverted to or away from functional components).

The present invention systems and methods facilitate increased die yields by flexibly changing the operational characteristics of functional components in an integrated circuit die. The present invention system and method enable integrated circuit chips with defective functional components to be salvaged. Defective functional components in the die are disabled in a manner that maintains the basic functionality of the chip. A chip is tested and a functional component configuration process is performed on the chip based upon results of the testing. If an indication of a defective functional component is received, the functional component is disabled. Workflow is diverted from disabled functional components to enabled functional components.
