Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. The scope of the invention is defined in the claims appended hereto.
Referring to the FIG. 1, the body-carryable, digital storage medium, audio/video recording assembly 10 is shown in functional block diagram form. The body-carryable, digital storage medium, audio/video recording assembly 10 includes an analog audio/video generating source 15, such as a miniature camera, which produces a video signal and an audio signal. There is a conductor means 20, such as a wire or cable, for transmitting the audio/video signal from the audio/video signal source 15 to an audio/video signal recording assembly device 25 for receiving and recording the audio/video signal. The recording device assembly 25 includes an audio/video signal input means 30, a date/time stamp means 35 for dating the input audio/video signal, an analog/digital converter means 40 and a digital/analog converter means 45, for converting the analog signal from the generating source 15 to a digital signal and for converting the digital signal back to an analog signal for later viewing. An integrated circuit processor means 50 controls the signal conversions and storage thereof. A removable, random accessible digital storage medium, such as a digital hard drive storage assembly 55 having a removable hard drive member 80 therein, records the digital signal. Also included is a battery means 60 for powering the recording device assembly 10 and an audio/video signal output means 65 to conduct the stored audio/video signals to an output device 70, such as a monitor, for viewing.
An analog audio/video signal from the audio/video source 15 input to the recording device assembly 25 is converted to a digital audio/video signal by the analog/digital converter means 40. The digital audio/video signal is stored on the hard drive member 80 of the digital hard drive storage assembly 55. The stored digital audio/video signal is randomly accessible via the integrated circuit processor means 50. The accessed audio/video digital signal is converted to an analog audio/video signal by the digital/analog converter means 45 and is viewed on an audio/video display device 70 connected to the recording device assembly 25 via the audio/video signal output means 65.
The integrated circuit processor means 50 provides random access to the digital data stored on the hard drive member 80 of the hard drive assembly 55 so that various segments of recorded events can be readily accessed. The integrated circuit processor means 50 also contains control software for audio/video compression and decompression and recording. Further, the hard drive member 80 can be readily removed from the hard drive assembly 55 when the hard drive member 80 is full. Inserting a fresh hard drive member 80 provides extended recording and archiving capabilities.
The audio/video camera 15 is sufficiently small that it is easily concealed on the body of an individual. Likewise the recording device assembly 25 is small enough for facile concealment on the body of an individual. The conducting member 20 between the camera 15 and the recording device assembly is preferably a hard conductor to prevent detection of a signal transmitted through space. A low power RF transmitter (not shown), associated with the analog A/V source 15, and an RF receiver 75 may be substituted for the conducting member 20 for certain application with comparable results. The RF receiver 75 provides the audio/video signal input means 30 for the recording device assembly 25.
Referring now to FIG. 2, a more detailed functional block diagram of the recording assembly 10 is shown. The analog audio/video generating source 15 is a miniature camera with audio input capabilities and available from BTS. In this embodiment, the A/V source 15 transmits a signal to the A/V RF receiver 75. The analog video signal is converted to digital form by the video A/D component 40a, available from Philips, while the analog audio signal is converted to digital form by the audio A/D component 40b, also available from Philips. The digital audio and video signals, under the control of the integrated circuit processor 50, are encoded and compressed into mpg format and passed to the hard drive assembly 55 for storage on the hard drive member 80. The integrated circuit processor 50 is available from Cirrus, and the hard drive assembly 55 is available from Toshiba.
In a preferred embodiment of the invention, power for the unit is provided by a pair of rechargeable batteries 60 available from Sanyo. A charger adapter 62 is available for recharging the batteries from a suitable outside power source.
Power to the system is provided by charging the battery pack 60 via an external power pack available from Astrodyne.
The hard drive assembly 55 is available from Toshiba and has a hard drive member 80 with at least 512 Mb of storage space. The digital audio/video data are accessed from the hard drive member 85 via a PCMCIA interface 85 with the signal passing through an ATA connector 90 to a 68-pin ATA PCMCIA 95, then converted back to an analog signal for display on an output device 70.
In order for the hard drive, audio/video recording assembly 10 to be carried on the body of an individual without drawing attention, the recording device assembly 25 is configured to occupy a small volume. One embodiment of the configuration of the components of the recording device assembly 25 is shown in FIGS. 3-8 where several views of the recording device assembly 25 are provided.

The side sections 215 form exterior channels 220 on opposed sides of the case inner portion 210, best seen in FIG. 19. The open ends of the case inner portion 210 are each covered by an end section 225, each having a protruding pin member 230 that connects each end section 225 to the case outer portion 250. The case outer portion 250 is composed of two pairs of mating sections 255 shown in FIG. 17. Each pair of sections 255 forms half of the case outer portion 250. Each pair of sections 255 includes a pin-accepting aperture 260 that mates with a pin member 230 of the inner end section 230. Each pair of sections 255 also includes a pair of thumb screw members 265 that extend into one end of one exterior channel 220 of the case member inner portion 210. Thumb screw members 265 from opposed pairs of sections 255 engage within the exterior channel 220 to securely fasten the pairs of sections 255 together about the case inner portion 210, as well as secure the inner end sections 225 of the case inner portion 210 against the side sections 215 thereof. The multilayer case member 200 provides a secure barrier to the environment exterior the case member 200. The multilayer case member 200 allows for concealment of the recording device assembly 25 in an obscure location, such as burial in the ground. In this embodiment, the analog audio/video signal is transmitted from the camera 15 via an RF signal, which is picked up by the RF receiver component 75 of the recording device assembly 25.
While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
