Boat docking backstop

A device that attaches to the center of a boat slip so a boat entering the slip will engage the device. The device consist of a central vertical member having a horizontal support bar on one end so that the horizontal support bar is approximately centered with respect to the vertical member and is approximately perpendicular thereto. Each end of the horizontal support bar is provided with a forwardly inclined leg that engages the rear end of an approaching boat as the boat backs into the boat slip. Each leg is capable of flexing slightly rearward when engaged by the boat to slow and stop the boat, preventing damage to both the boat and the dock. An alternate embodiment eliminates the vertical member.

A stand-off, non-invasive acoustic detector for monitoring physical activity and/or breathing activity of children and infants. According to a preferred embodiment, the present invention comprises a two-phase output oscillator coupled to an ultrasonic transmitter and microphone. A respective one of the outputs of the oscillator drives the ultrasonic transmitter, through a power amplifier, which sends out an ultrasound wave. The echo return is picked up by the microphone and thereafter band passed to isolate those frequencies falling within 33 to 40 kHz. Such signal is further adjusted for automatic gain control. The resultant echo return signal is compared to the respective other output of the oscillator, the latter also being adjusted for automatic gain control, which are then combined via a summing junction to produce a resultant signal, the latter being utilized to drive a phase comparator and an alarm timer. To the extent the resultant signal, which corresponds to continuous breathing activity or physical activity, deviates substantially from the signal produced by the comparator for a sufficient length of time, an alarm is activated to signal either abnormal breathing activity or a lack of breathing activity, the latter indicative of either a medical condition, such as SIDS, or the absence of the child from the monitored area.

Stand-off non-invasive acoustic baby monitor

Method and apparatus for detecting coronary stenosis. The apparatus comprises an acoustic sensor and a microcomputer that identifies the standard S1 and S2 heart sounds, heart rate, and determines the diastolic interval of the subject and thereafter estimates the acoustic energy levels within a 2 octave band around approximately 20 Hz during diastole. Based upon such estimation, a diagnosis can be rendered as to the presence and degree of stenosis from the coronary artery.
