A vehicle includes a propulsion unit configured to move the vehicle and to change a characteristic of the environment of the vehicle. The vehicle also includes a proximity sensor configured to detect the characteristic of the environment of the vehicle. The characteristic of the environment is changed by operation of the propulsion unit. The vehicle further includes obstacle detection circuitry configured to determine a presence of an obstacle in the vicinity of the vehicle based on a comparison between the detected characteristic of the environment and a reference value.

Obstacle detection

A telephone apparatus connects to a telecommunications network via an exchange line. It has signal recognition for detecting and recognizing calling line identity (CLI) and called number identity (CNI) signalling transmitted over the exchange line. The apparatus causes an incoming call to be transferred to a second exchange line in response to specified CLIs and/or CNIs.
