This invention provides a family of improvements to video security systems. In a first embodiment, a television set employed for normal television viewing is switched to be the monitor of the security system only upon the happening of a security violation event as sensed by a sensor. I one variation thereof, the switching capability is built into a dual-deck VCR along with the ability to reset the system to normal television watching by means of the remote control for the VCR. In another embodiment, the video cameras of the system are made easily adjustable and relocateable by the use of a bi-directional wireless transmission system linking the cameras to the base station and monitor. Video is sent from the cameras and control signals to adjust the field of view of the cameras are sent without the need for connecting cables. In another variation and improvement on the latter embodiment, a video camera is mounted on a mobile platform so as to be moveable and guidable to locations within a security monitoring area.
The toy vehicle video production system for creating full-motion real time video images of a toy target vehicle includes a toy vehicle, a first wireless transmitter, and a first wireless receiver operatively coupled to the toy vehicle and configured to control movement of the toy vehicle in response to signals received from the first wireless transmitter. A video camera mounted to the toy vehicle generates real-time video images of the toy target vehicle while a camera controller connected to the video camera controls movement of the video camera relative to the toy vehicle. The invention also includes a second wireless transmitter and a second wireless receiver operatively coupled to the camera motion controller and configured to control movement of video camera in response to signals received from the second wireless transmitter. A video recorder operatively coupled to the video camera records the real time video images generated by the video camera and a video display device operatively coupled to the video camera displays the real time video images. Movement of the toy vehicle and movement of the video camera are controlled in real time in response to the video images displayed on the display device so that optimal video images of the toy target vehicle are obtained.
An object of the present invention is to provide a sensor system which can effect local communications suitable for exchanging information to avoid collisions between mobile robots. The sensor system also prevents collisions between the mobile robots and obstacles. The system is well-suited for a multi-robot environment where multiple mobile robots operate. The system includes infrared signal transmitters installed in each of the multiple mobile robots for sending transmission data via infrared signals. The system further includes infrared signal receivers installed in each of the multiple mobile robots for receiving the transmission data sent by the infrared signal transmitters. Each mobile robot includes a control unit. The control unit prepares transmission information which includes mobile robot identification information unique to the mobile robot. The transmission information is included in the transmission data sent from the infrared signal transmitter. The control unit also extracts transmission information which is received by the infrared signal receiver.
A driveway security sensor having a ground-engaging member connected to a housing body. The ground-engaging member substantively has the shape of a slake. A swivel member is pivotally connected to the housing body, and a motion sensor is connected to the swivel member.
The video-assisted remote control device disclosed comprises a remote control station and a station on board the machine to be remote controlled. The latter comprises a real-time mixing unit, a video and audio transmitter and a remote control receiver. The control station comprises several monitors, a video and audio receiver and a remote control transmitter. Application to the remote control of public works machines.
A surveillance system having two or more monitoring devices moving on a single track. The monitoring devices are suitably video cameras but may also include audio monitoring. Power for the monitoring devices, control signals and signals from the monitoring devices are all transmitted on the track. Power is suitably DC and other signals are suitably RF. The system incorporates collision avoidance means to prevent collision between adjacent moving cameras. The collision avoidance means includes hand-over software so that a person can seamlessly scan a region with camera control being passed to adjacent cameras to avoid collision.
