DESCRIPTION OF A PREFERRED EMBODIMENT

The weapon system illustrated in FIG. 1 comprises a weapon sight assembly, generally designated 10, mounted on a weapon, in this case a rifle; and portable communication apparatus, generally designated 20, constructed for carrying by an individual operating the weapon, namely a combatant-soldier, for establishing communication between the weapon sight assembly 10 and a commander 30 or headquarters 40 at a distant location. As will be more particularly described below with respect to FIGS. 2 and 3, a two-way short-range communication loop is established between the weapon system sight assembly 10 and the portable communication apparatus 20; and a long-range two-way communication loop is established between the portable communication apparatus 20 and the distant location of the commander 30 or headquarters 40.

The weapon sight assembly 10 mounted on the rifle illustrated in FIG. 1 is more particularly shown in FIG. 2. It includes a weapon sight 11 of any desired type to facilitate orienting the weapon in alignment with a target in the field of view, and a platform 12 for mounting the weapon sight assembly on the rifle (or other weapon) e.g. via clamps 12a.

Weapon sight assembly 10 further includes a video camera 13 carried by platform 12 for generating and outputting video signals corresponding to the viewed field. It further includes a short-range video transmitter 14 for transmitting such video signals to the portable communication apparatus 20. The range of video transmitter 14 is very short, preferably in the order of one meter or less, only sufficient to communicate with the proximally-located portable communication apparatus 20.

Weapon sight assembly 10 further includes: a digital compass 15 of any known type for determining the direction of orientation of the weapon (rifle) and for outputting data signals corresponding to such determined orientation; a data projector 16 for optically projecting in the field of view data from the digital compass 15; and a short-range data transceiver (transmitter/receiver) 17 also in communication with the proximally-located portable communication apparatus 20.

As illustrated in FIG. 2, the weapon sight assembly 10 may also include a global positioning system (GPS) unit 18 for geographically locating the respecting weapon and for outputting data signals corresponding to the geographical location. Such data may also be transmitted by the short-range data transceiver 17 to the proximally-located portable communication apparatus 20.

The control of all the foregoing components carried by the weapon sight assembly 10 is effected by a controller 19 also mounted on platform 12 of assembly 10.

The portable communication apparatus 20, as shown in FIG. 3. includes two separate units 21, 22, cable-connected together as shown at 23. Unit 21 is the larger of the two and is constructed so as to be attachable to the body of the individual (soldier-combatant) operating the weapon (rifle). For example, unit 21 may include clips 21a attachable to a protective vest worn by the individual. Unit 22, the smaller of the two units, is constructed so as to be attachable to the arm, or to be carried by the hand, of the individual operating the weapon for convenient reviews by the individual; for example, unit 22 could be strapped to this arm, or attached by a bracket to the protective vest of this individual.

Smaller unit 22 is used primarily as a monitor for viewing the video information generated by the video camera 13 in the weapon sight system 10, or for viewing commands, instructions or other information transmitted to the individual operating the weapon by his commander 30 or by headquarters 40. Accordingly, the smaller unit 22 may be similar in size and construction to a personal digital assistant (PDA) having a screen 24 for displaying the foregoing information.

As shown in FIG. 3, the larger portable communication unit 21 (e.g., constructed so as to be vest-worn by the individual) includes a short-range video receiver 25 and a short-range data transceiver 26 for communication with the short-range video transmitter 14 and the short-range data transceiver 17, respectively, of the weapon sight assembly illustrated in FIG. 2. Portable communication unit 21 further includes a long-range video transmitter 27 and a long-range data transceiver 28, e.g., having a range of several hundred meters, sufficiently for communicating with the remotely-located commander 30 or headquarters 40 (FIG. 1). The foregoing components of the vest-worn portable communication unit 21 are all controlled by a controller 29 included within that unit.

It will be seen that weapon system, including a weapon sight assembly as illustrated in FIG. 2 and portable communication apparatus as illustrated in FIG. 3, provides a number of advantages which can be particularly important during combat conditions.

Thus, the soldier-combatant carrying the weapon (e.g. rifle) may use the weapon also to see around a corner or over an obstacle. This can be done without exposure to possible enemy fire by merely orienting the weapon carrying the sight assembly such that the video camera 13 on that assembly views the region of interest. The video signals outputted from the camera are transmitted via the short-range transmitter 14 to the proximally-located portable communication unit 21. The latter unit is cable-connected to the smaller monitor unit 22 such that the video signals received by the short-range video receiver 25 of portable communication unit 21 are displayed to the soldier-combatant on the screen 24 of the smaller arm-carried or hand-held unit 22.

Since the sight assembly 10 mounted on the weapon requires only short-range communication (e.g. of less than one meter) with the portable communication unit 21, the sight assembly may of relatively light weight so as to impose a minimum load on the weapon itself. Also, since the communication between the sight assembly 10 and the portable communication unit 21 is wireless, the communication with the portable communication unit 21 imposes no interference or awkwardness in the use of the weapon.

Further and as noted above, the portable communication unit 21, which includes not only the short-range communication equipment for communicating with the weapon sight assembly 10 but also the long-range communication equipment for communicating the commander 30 and/or headquarters 40, is constructed so as to be conveniently carried on the body of the individual soldier-combatant, e.g. by attachment to the combatant's vest. The communication unit therefore also imposes very little restriction on the movements of the individual combatant/soldier. In addition, since the actual field of view is displayed by the small monitor unit 22, which can also be conveniently carried and maneuvered by the individual (e.g., by being strapped to the individual's arm or carried by the individual's hand), the field viewed by the video camera 13 on the weapon sight assembly 10 may be conveniently seen by the soldiers-combatant whenever desired.

The weapon sight assembly 10, and the portable communication apparatus 20 communicating with it, also serve as an important intelligence gathering means for real-time gathering and transmitting, to a commander or to headquarters, information regarding battlefield conditions. Thus, the video information from video camera 13, digital compass information from digital compass 15, and/or geographical information from GPS unit 18, all on the weapon sight assembly 10, may be transmitted to the commander 30 and/or headquarters 40 via the portable communication unit 21. Further, the commander 30 and/or headquarters 40 may communicate commands, instructions or other information to the individual soldier/combatants via the long-range receivers in communication unit 21. Such commands, instructions or information may also be displayed on screen 24 of the small monitor unit 22 carried by the individual.

In addition, controller 19 carried by the weapon sight assembly 10 can be directly controlled by the remotely-located commander 30 and/or by headquarters 40 to initiate operation of the video camera 13 carried by the weapon sight assembly 10 whenever desired, or to terminate its operation, e.g. in order to display urgent information or an urgent command to the individual soldier/combatant on the small monitor unit 22.

While the invention has been described with respect to one preferred embodiment, it will be appreciated that many variations and other applications may be made. For example, the weapon sight assembly 10 could omit one or more of the above-described components, e.g., the GPS unit 18 or the digital compass unit 15. Alternatively, the weapon sight assembly could include additional components, e.g., a microphone to enable voice communication with the commander or headquarters.

Many other variations, modifications and applications of the invention will be apparent.
