Abstract: An infant monitoring system includes a bladder configured for communication with an infant having a mass and measurable biological functions and properties. The bladder contains a substantially non-toxic fluid adapted to transmit fluid pressure. The infant monitoring system also includes a single pressure sensor that selectively monitors the fluid pressure. The pressure sensor detects a presence of the infant by monitoring for a substantially continuous pressure due to the mass of the infant. The infant monitoring system also includes an electronic module operatively connected to the pressure sensor, which electronic module receives a signal indicative of the fluid pressure monitored by the pressure sensor. The electronic module emits a notification if the signal is substantially outside of a predetermined boundary.

Abstract: A manually-operated control for generating a vector signal comprises a handle with an elongate axis pivotally mounted to the housing for universal rotation about a pivot point on the axis of the handle. An imaged surface moves in two directions with the rotation of the handle about two perpendicular axes intersecting at the pivot point. A camera and LED are focused on the imaged surface. A microprocessor-based controller inputs and processes images sequentially input from the camera for detecting and quantifying the movement of the imaged surface in two directions and generates a vector signal indicative thereof.

Abstract: A device for invasively measuring fluid pressure is disclosed. The device includes a disposable housing having a fluid contacting area and a non-fluid contacting area. A disposable diaphragm in a substantially non-elastic state is disposed within the housing and separates the fluid contacting area from the non-fluid contacting area. A side of the diaphragm is adapted to contact the fluid, and the diaphragm has sufficient flexibility to move a distance axially within the non-fluid contacting area in response to fluid contact. The distance is substantially proportional to the fluid pressure. An electronic sensing device is removably attached adjacent the non-fluid contacting area of the housing, and is spaced from the diaphragm. The electronic sensing device is capable of determining the fluid pressure.

Abstract: An apparatus and method sensing the absolute position of a gauge. A pointer having a predefined rotation with a circular travel pattern. At least one light emitting diode that generates an optical signal. An optical sensor placed in a fixed position along the circular travel pattern of the pointer. A pointer driver for driving the pointer.
