  • Patent number: 7846103
    Abstract: An improved probe guide and probe guide system for use in conjunction with a medical imaging device is disclosed. The medical imaging device may be any type of imaging device that generates a cross-sectional image of a portion of a patient's body in a single image plane, such as, ultrasound, CT, or MRI imaging devices. The probe guide allows maintaining the movement of the probe within the image plane and accurate placement of a probe, such as a biopsy needle, by allowing a range of angular translation of the probe. The probe guide system enables extrapolation of the penetration path of the probe held by the probe guide and superimpose it on to the cross-sectional image allowing the medical personnel to view the penetration path of the probe within the patient in advance.

  • Patent number: 7669471
    Abstract: A fluid flow tester for measuring minute volumes of fluid and for calibrating medical devices, such as intravenous infusion pumps, includes a plurality of valves and associated conduits which direct fluid from the device being tested to a transparent vertical column. A plurality of sensors, each including a light emitting diode and a light detector, are arranged along the axial length of the column at a predetermined spacing between adjacent sensors. Fluid from the device being tested is directed through the flow tester by the valves and associated conduits into the column where it rises. The meniscus of the fluid rising in the column is detected by the sensors. The sensors provide signals to a microcontroller which calculates the time that it takes for the fluid to pass each sensor. Knowing this timing and the volume of the column, the flow rate of the fluid may be calculated by the microcontroller.

  • Patent number: 7529156
    Abstract: By enabling its users to see and thus more vividly experience local solar day and local solar night, etc., the Synclecron invention seeks to somewhat alleviate the modern-day problem of human separation from the flows and ebbs of natural time. It does so via providing a way of mapping and displaying the experiential passage of solar and other day and night to conventional displays of conventional time. The Synclecron invention achieves this by two means. First by utilizing waxing & waning, journeying pairs of hieroglyph circles that alternately travel twice a day through a hieroglyph sky around a hieroglyph earth. And, last, by using a rotating “minute-hour” indicator, which displays where the Synclecron invention's user is in local natural time during each “natural” one-twelfth hour of his or her local natural day and natural night.
