Abstract: A wireless local television transmission system with related methods, apparatus, and components. There is a source of a video signal to be viewed at a remote location such as a TV camera, cable select box, antenna, or VCR. An up converter is connected to the source for shifting the video signal to a frequency above the normal television bands. A transmitter is connected to the up converter for transmitting the video signal at the shifted frequency. A receiver is disposed at the remote location for receiving the transmitted video signal. A down converter is connected to the receiver for shifting the video signal back down to a frequency within the normal television bands and identified with a known channel. Finally, conventional television set functions are connected to the down converter for processing and displaying the video signal on the known channel.

Abstract: A keyboard to facsimile transmission device allowing the direct imputting of a sequence of identifying signals representing alpha-numeric characters and delimiters comprising a message to be transmitted to a facsimile machine for printing thereby. The messages are input to a keyboard employing an LCD display panel in a text editing mode. The messages are digitized from stored font definitions and output on a line-by-line basis in the form of a pseudo page including spacing areas of non-characters inserted by the logic according to a pre-established page definition. Stored forms character sequences can be intermeshed with inputs from the keyboard to allow the user to operate in a self-prompting mode. A digitized signature or small hand drawing can be inserted with the text for transmitting orders, checks, credit vouchers, or the like, requiring a verifying signature. The font definitions include pixel replication for reduced memory and time requirements. Both military and commercial applications are described.

Abstract: An adhesive photocopyable transparency for use in a secure facsimile transmission system wherein one of two partial documents each containing portions of an original document which are complementary and mutually exclusive is photocopied onto the transparency and overlayed on the other of the two partial documents in registration therewith to recreate the original document. There is a rectangular sheet of a transparent plastic material having a surface for accepting and holding a photocopy image. An adhesive material is disposed at an edge of the sheet of plastic material and a removable protective covering is disposed over the adhesive material so as to allow the transparency to pass freely through a photocopy machine and be slid on the surface of a document without the adhesive material interfering therewith.

Abstract: A security method and apparatus for use in providing an "invisible envelope" for facsimile transmission thereby avoiding the casual reading of documents by persons interposed between the receiver of the transmission and the ultimate designated recipient thereof. Each page of the document is pattern divided into two portions which are individually unreadable in an easy and straightforward manner. The two portions are sent in sequence (i.e. at different times) and then the original document is reconsitituted at the receiving end by the designated recipient employing a transparency overlay process with the two portions. The patterning at the transmitting end may be accomplished by an optical filtering process or may be computer generated as by modifying word processing software or by a separate program manipulating a pre-input document to produce the two portions for printing and transmission. The HideaFAX.TM. process of this invention is applicable to conventional FAX machines without modification.

Abstract: A device for photocopying a document to produce two partial documents for secure transmission. A transparent sheet is placed on the cover glass and has a pattern thereon of portions which are complementary along longitudinally equal shift distances. There is a frame having the transparent sheet attached to the bottom thereof and including parallel side members. A holder is disposed within the frame and on the transparent sheet between the side members for longitudinal sliding a document over the pattern between a first position and a second position located at the equal shift distance. The holder comprises a top member and a transparent carrier member slidably disposed on the transparent sheet and attached to the top member for sliding movement in combination therewith with a document to be photocopied therebetween. The holder is moveable between the first position and the second position. A combined stop and detent prevents the holder from sliding too far and resiliently holds the holder in the positions.

Abstract: A bottle for holding, mixing, and dispensing an adjustable SPF mixture of a lotion and a liquid containing a sunscreening agent. There is a plastic bottle containing first and second compartments for containing, respectively, the lotion and the sunscreen agent-containing liquid and having a cylindrical neck at the top thereof containing a first bore therethrough communicating with the first compartment and a second bore therethrough communicating with the second compartment. The first bore is concentrically disposed in the neck and sized for passing known quantities of the lotion with the second bore being peripherally disposed with respect to the first bore and sized to add a quantity of the sunscreen agent which will impart a pre-selected maximum SPF value to dispensed quantities of mixtures of the lotion and the sunscreen agent.

Abstract: A microphone/pickup system employing a digital signal throughout. There are a plurailty of digital microphone/pickup devices each comprising, a microphone/pickup element for sensing sound vibrations and for producing an analog electrical signal reflecting the sound vibrations at an output thereof. An analog to digital converter is directly connected to receive the analog electrical signal at an input thereof and produce a digital signal reflecting the sound vibrations at an output thereof, the output of the analog to digital converter being the output of the microphone/pickup device. Preferably, there is a support structure carrying each microphone/pickup element and its associated analog to digital converter in combination as well as a plurality of user devices disposed at a location removed from the support structure and operatively connected to receive and use the digital signal from respective ones of the digital microphone/pickup devices.

Abstract: A public payphone telephone system providing remote access by telephone devices to telephone lines. There are a plurality of public telephone access modules disposed in separated locations and operably connected to telephone lines for receiving remote telephone transmissions and for connecting them to the telephone lines. Each of the public telephone access modules includes visible indicia of its presence and location and a first interface module for wirelessly transmitting and receiving telephone communications by means of a beam of IR energy (or, alternatively, RF) energy. A remote telephone interface is operably associated with each of the telephone devices for interfacing between the telephone device and the public telephone access modules. Each remote telephone interface includes a second interface module for transmitting and receiving telephone communications by means of the beam of IR energy.

Abstract: An improved automated irrigation system having localized moisture needs input to the control function. There is a sprinkler head connected to a supply of water under pressure by a pipe having a valve therein. A moisture sensing probe is placed in the soil adjacent the sprinkler head for developing an electrical signal representing the moisture content of the soil surrounding the probe. There is irrigation bypass logic disposed at the probe and operably connected to the valve and the probe for comparing the moisture content of the soil surrounding the probe to pre-established limits and for preventing the valve from supplying water to the sprinkler head when there is sufficient moisture in the soil. A timer controller can be employed to provide operating power to the system only at preferred times for watering. The moisture parameters for watering are adjustable. There is a wirelessly connected version eliminating wires between the probes and the valves.
