Abstract: This invention relates to a parachute sea anchor system deployable from a payload tube. There is provided a parachute sea anchor system suitable for launch from a vessel comprising at least one payload tube, said payload tube, comprising a payload canister, which comprises a parachute sea anchor, wherein said parachute sea anchor comprises a buoy tethered thereto, wherein said payload canister is attached to said vessel.

Abstract: An illuminating timing device comprised of an integrated base unit and software, three pedal position foot controls, standard printer, and a re-printable template capable of providing an economical means of performing periodontal depth charting quickly and easily by one person with minimal risk of contamination.

Abstract: A patient privacy screen device to be used in conjunction with a hospital or ambulance gurney while a patient is being cared for or transported from one place to another. The device allows quick and effortless erection of two solid side curtains and one solid head by the medical attendees.

Abstract: A system for measuring properties of a medium includes an electromagnetic generator for forming a CW carrier, a digital encoder for forming a digital message, and a modulator for modulating the CW carrier with the digital message to form a digitally modulated CW carrier. The medium provides a channel for propagating the digitally modulated CW carrier. The system further includes a receiver configured to receive the propagated, digitally modulated CW carrier, and a processor for measuring at least one property of the medium. The medium may be disposed within a gaseous atmosphere, a body of water, or a cell of a laboratory.

Abstract: An image reproduction apparatus includes a scanning unit, a transparent scanning bed optically coupled to the scanning unit, and an adjustable shade associated with the scanning bed, wherein the adjustable shade is configured to be selectively placed across the scanning bed to reduce a portion of the scanning bed.

Abstract: Remotely sensing a target may include generating a first beam of optical radiation that is modulated at a first frequency and polarized at a first polarization. A second beam of optical radiation that is modulated at a second frequency and polarized at a second polarization may also be generated. The first and second beams of optical radiation may be transmitted to the target. Radiation at the first polarization and radiation at the second polarization may be detected from the target using a phase sensitive technique and the first and second frequencies.

Abstract: A pan and tilt camera system is provided. The system involves positioning a payload (e.g., camera, sensor, controlling electronics) with its center of mass substantially centered over both the pan and tilt axes, which facilitates increasing the payload of a pan and tilt system by reducing and making more constant the load on panning and/or tilting motors. With the more constant motor loads, smoother and finer camera and/or sensor control is possible than with conventional systems. Example systems also provide for belt drive motors, a survivable casing, and a casing adapted for a larger variety of lens sizes.
