1. A method for indicating presence of an object through a physical barrier, comprising:
transmitting at least one wideband energy burst, said at least one wideband energy burst reflecting off said object and producing at least one return signal; and
receiving said at least one return signal to indicate presence of said object, at least one of said transmitting of said at least one wideband energy burst or said receiving of said at least one return signal being through said physical barrier.
2. The method of claim 1, wherein said transmitting and receiving occur at different locations.
3. The method of claim 1, wherein said receiving occurs at a plurality of locations.
4. The method of claim 1, wherein said at least one wideband energy burst comprises at least one of radio frequency energy or sonic energy.
5. The method of claim 1, wherein said receiving and transmitting uses one or more antennas.
6. The method of claim 5, wherein at least one of said one or more antennas comprises one or more directional antennas, one or more omni-directional antennas or an antenna array.
7. The method of claim 6, wherein said antenna array comprises antennas generally arranged in parallel rows and parallel columns, said parallel rows being generally perpendicular to said parallel columns.
8. The method of claim 1, wherein said receiving comprises beam steering.
9. The method of claim 1, wherein said receiving occurs at one or more selected time delays after transmitting, wherein said one or more selected time delays correspond to one or more selected object ranges.
10. The method of claim 9, wherein said one or more selected time delays are one of sequentially incremented or sequentially decremented, and wherein said one or more time delays correspond to a scan of selected ranges.
11. The method of claim 10, wherein said scan of selected ranges is compared to a later occurring scan of selected ranges to determine at least one characteristic of said object.
12. The method of claim 11, wherein said at least one characteristic comprises at least one of motion characteristic, a position characteristic, a size characteristic, or a reflectivity characteristic.
13. The method of claim 1, further comprising differentiating between broad boundary objects and sharp boundary objects.
14. The method of claim 1, further comprising displaying the position of said object in one of two-dimensional coordinates or three-dimensional coordinates.
15. The method of claim 1, further comprising filtering said received signal return signal to sense velocity of movement of said object.
16. The method of claim 1 further comprising coherently detecting and integrating the return signal.
17. The method of claim 1, wherein said physical barrier comprises a wall.
18. A radar system for indicating presence of an object through a physical barrier, comprising:
at least one transmitter for transmitting at least one wideband energy burst, said at least one wideband energy burst reflecting off said object and producing at least one return signal; and
at least one receiver for receiving said at least one return signal to indicate presence of said object, at least one of said transmitting of said at least one wideband energy burst or said receiving of said at least one return signal being through said physical barrier.
19. The radar system of claim 18, wherein said at least one transmitter and said at least one receiver are at different locations.
20. The radar system of claim 18, wherein said at least one wideband energy burst comprises at least one of radio frequency energy or sonic energy.
21. The radar system of claim 18, wherein said at least one receiver and said at least one transmitter comprise one or more antennas.
22. The radar system of claim 21, wherein at least one of said one or more antennas comprises one or more directional antennas, one or more omni-directional antennas or an antenna array.
23. The radar system of claim 22, wherein said antenna array comprises antennas generally arranged in parallel rows and parallel columns, said parallel rows being generally perpendicular to said parallel columns.
24. The radar system of claim 18, further comprising a display for displaying the position of said object in one of two-dimensional coordinates or three-dimensional coordinates.
25. The method of claim 18, further comprising a filter for filtering said received signal return signal to sense velocity of movement of said object.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of communicating video information to a remote display system, said method comprising:
receiving a display request for displaying information on said remote display system;
writing said data display request to a video frame buffer associated with said remote display system if said display request comprises a request not associated with displaying a digital video stream;
transmitting digital video from said display request to said remote display system if said display request comprises an encoded video stream request that can be decoded by said remote display system; and
transcoding digital video from said display request before transmission to said remote display system if said display request comprises an encoded video stream request that cannot be decoded by said remote display system.
