  • Video ⁇ P 27 is coupled to the internal electronics of focal plane array 25 to permit the output of data from optics 23.
  • Connection 59 couples video ⁇ P 27 with DPS/FPGA 37.
  • DSP/FPGA 37 sends a control signal to focal plane array 25 to read out specific pixels (included in the focal plane array) for purposes of calibrating focal plane array 25 and the gains and offsets used to correct for focal plane anomalies.
  • focal plane array 25 can also be used as a temperature sensor, thus eliminating the need for temperature sensor 43.
  • internal electronics reads a specific set of pixels and sends the corrected data, including temperature, back to DSP/FPGA 37 via video ⁇ P 27 and connection 59.
  • Eyepiece 19 is, preferably, a micro optical VGA heads up display which, in operation, can be repeatedly attached and detached (without tools) from housing 21 via any conventional, mechanical connector illustrated schematically at 18 and 20. See, particularly, Figure 2A. Though physically detachable, eyepiece 19 is still, via connection 67, connected to housing 21 and DSP/FPGA 37.
  • Antenna 29 is, preferably, a conformal patch antenna which sends and receives RF signals.
  • Received RF signals are transmitted to GPS/GLONASS 33 via connection 71.
  • RF signals are also transmitted to radio frequency transceiver 31, via connection 73.
  • Radio frequency transceiver 31 is a software definable radio (SDR) which can be used as a cell phone, a satellite phone (in either case accelerometer 41, because of its sensitivity, is used as the speaker), a generic receiver (within the frequency range of the antenna 29), and as a generic transmitter (again within the frequency range of antenna 29).
  • Radio frequency transceiver 31 sends the base band information content of the RF signal to DSP/FPGA 37 over connection 75. Signals from DSP/FPGA 37 to radio frequency transceiver 31, to control its configuration and transmit data to a remote location, are also sent over connection 75.

They provide parallel, redundant time keeping and user location functions. The NMEA-0183 protocol is used for both. GPS/GLONASS 33 is connected to processor 37 via connection 77 which permits the transmission of signals to GPS/GLONASS 33 (where am I? time, or both) and data back (location, time, both).
  • Compass 35 is a digital compass which sends a signal to DSP/FPGA 37 via connection 81.
  • Temperature sensor 43 is optional, depending on whether focal plane array 25 is used to measure temperature. When incorporated, it is connected to DSP/FPGA 37 via connection 85
  • Accelerometer 41 includes three independent micro electro mechanical structures (i.e., MEMS devices) which measure change of motion on three different axes (i.e., x, y and z). Each of the three MEMS devices independently sends, via connection 83, a signal corresponding to a dc voltage to DSP/FPGA 37. Each signal ranges from 0 (which represents the at rest position) to 2 volts (which represents full scale movement).

  • the processor portion of DSP/FPGA 37 is, preferably, a 16 bit digital signal processor.
  • a processor has a number of features which make it desirable in the present invention (e.g., 9 different power management zones and multiple internal busses, which permits data to come in and out independently).
  • the processor portion is capable of moving large amounts of data and, in parallel, simultaneously processing arrays of information and commands. This permits the real time fusion (i.e., combining) of different data from various inputs (e.g., preloaded information, video ⁇ P 27, antenna 29, accelerometer 41 , etc.) and commands (as discussed below).
  • the use of a DSP also has the advantage of conserving power, hence battery life is optimized.
  • the FPGA within the DSP/FPGA combination provides for the programmable and reconfigurable aspects of the functionality of system 1 1.
  • the FPGA off-loads from the DSP portion certain signal processing and data manipulation functions. It performs all functions significantly faster than can the DSP portion alone. It functions as a digital pre-, and post-, processor for a variety of data types (e.g. navigation, communication), the processing of large volumes of matrixed data (i.e. multiple images), and their filtering.
  • User specific I/O functions e.g., USB or 1394 can be programmed into the FPGA portion to allow users to integrate to their current system architectures without changing the hardware design.
  • housing 21 also supports a battery 17, card slot 45, a touch pad 49, and a USB data port 47.
  • card slot 45 is a Type Il PC card slot which has a generic open spec. Alternately, where RF communications are not required, a 3COM type card slot can be used. For military applications a VDC 400 card slot can be used. Regardless of the type, a variety of pre-programmed data (depending upon the specific application(s) for which system 1 1 is being used) is input to DSP/FPGA 37 via card slot 45 and connection 91.
  • Touch pad 49 includes course (i.e., finger) and fine (e.g. stylus) manipulation controls.
  • the finger control is used to control the cursor visible in the screen of heads up display 19.
  • the stylus control can be used for inputting data (such as is done with a Palm Pilot) and handwriting recognition.
  • Touch pad 49 is connected to processor 37 via link 93.
  • USB data port 49 which is connected to DSP/FPGA 37 via link 92, is used to provide external command and control to/from other systems (e.g., a laptop computer).

  • the applications code(s) runs on top of the operating system to perform the functions set forth herein.
  • memory 39 Connected to processor 37 via connection 95 is memory 39, which includes non-volatile type (e.g. flash RAM), which is not affected by power, and volatile, which is affected by power.

  • power supply 17 is a Li Ion battery.
  • a heads up display 19 which is essentially a miniaturized computer screen, an array of data is selectively provided to the user.
  • Inputs via cable 67, include functional menus, a multi-mode cursor, navigational and positional images, streaming LWIR images, communications interface, passive range finding function, and ballistic solution crosshairs.
  • the preprogrammed data can include terrain information, elevation data and 3-D topographical data. It can also include mission tasking information.
  • the updated data which comes via antenna 29 (from, for instance, satellite or aircraft or another system 1 1), can include corrections, updates and additions to any and all of the foregoing.
  • the LWIR corrected video stream can be overlaid with GPS information, temperature and crosshairs.
  • touch pad 47 via one's finger, controls the cursor visible on the screen to select the desired function from the various menus.
  • the floating crosshairs are, in conjunction with accelerometer 41, used for ballistics computations (except for wind speed), automatic target tracking and passive range finding.
  • system 1 1 can be hand carried by an operator and used during daylight and at night. It enhances night vision while providing a host of automatic user location functions.
  • the GPS and/or GLONASS 33 provide the user with global location to within 6m, while accelerometer 41 and compass 35 combination measures the users change in location and his/her direction.
  • DSP/FPGA 37 can combine these functions and add functionality by comparing two images of the same target taken at different angles, compare the motion of system 11 between images to derive range to a point in the image, and determine its exact location as well.
  • processor 37 can infer range to a moving object by pattern recognition (e.g. a vehicle passes in front of a light pole or the lines in a parking lot). Once a distance is estimated a velocity and direction can be inferred. A message can be sent to another monitoring location or, say, law enforcement officials, concerning these measurements. In fixed installation GPS/GLONASS 33 would be unnecessary.
