Abstract
Sensing apparatus includes a network camera, which is configured to capture images of a scene and to output a sequence of data packets containing digitized video data responsively to the images. A one-way link is coupled to the network camera so as to transmit the data packets from the network camera to a packet communication network.
Claims23
1-17. (canceled)
Sensing apparatus, comprising:
- a network sensor, which is configured to sense data and to output a sequence of data packets containing digitized sensed data;
- and
- a one-way link, physically configured to carry signals in one direction and to be incapable of carrying signals in the opposite direction, which is coupled to the network sensor so as to transmit the data packets from the network sensor to a computer.
Processor communication apparatus, comprising:
- a first processor configured to transmit data packets;
- a second processor configured to receive data packets;
- a first one-way link, physically configured to carry signals in one direction and to be incapable of carrying signals in the opposite direction, which is coupled to the first and second processors so as to carry data packets from the first processor to the second processor and to be incapable of carrying signals from the second processor to the first processor;
- a second one-way link, physically configured to carry signals in one direction and to be incapable of carrying signals in the opposite direction, which is coupled to the first and second processors so as to carry commands from the second processor to the first processor and to be incapable of carrying signals from the first processor to the second processor;
- and
- a switch on the second one-way link, which has a first state in which it allows transmission of commands to the first processor over the second one-way link and a second state in which it prevents transmission over the second one-way link.
3 more elements
A method for sensing, comprising:
- deploying a network sensor to sense a characteristic of an environment and to output a sequence of data packets containing digitized sensor data responsively to the sensed characteristic;
- and
- coupling a one-way link, physically configured to carry signals in one direction and to be incapable of carrying signals in the opposite direction, to the network sensor, so as to transmit the data packets from the network sensor to a computer.
