초록 ▼

A personal alert safety system, having visual and audio safety components, in a small, lightweight, high impact casing with two compartments separated by a planar wall providing a watertight wall between the two compartments, the planar wall being a sealed laminated piezoelectric sound transducer. One of the compartments is sealed to provide a watertight chamber containing the electronic and electrical control and operating circuitry for the system. The second compartment is a resonating chamber with sound ports for the piezoelectric sound generating transducer. Two manual switch operators are located on opposite exterior sides of the casing and in a sealed manner actuate switches in the interior circuitry to turn the unit on and off, and simultaneous operation of both switches is required to turn the system “on”or “off”. A vibrating accelerometer motion detector is included within and connected with the circuitry inside of the casing. There are several embodiments of each of the planar sound transducer and the vibrating accelerometer motion detector.

대표청구항 ▼

A personal alert safety system having condition responsive sensor means and alarm means indicative of personal safety conditions comprising: a small size portable casing, said casing comprising an internal divided two part chamber, the first part being a watertight sealed cavity and the second part being a sound resonating cavity with surrounding walls including at least one sound port providing a passage from the interior to the exterior of said resonating cavity; a sealed flat wall means comprising a dividing wall between said two chamber parts; electric and electronic control and operating circuitry means disposed in said first part of said chamber including a source of electric power, two series connected, single pole, push button control switches each having “on”and “off”positions and being spring biased to the “off”position, and flip-flop electronic switching means controlled by said control switches to enable said circuitry means to be turned “on”and “off”respectively by a sequence of simultaneous operations of said two control switches; said sealed flat wall means comprising a thin flat sound generating piezoelectric transducer device electrically connected to said circuitry means; a motion detector, and means rigidly mounting said motion detector within said first part of said two part chamber, said motion detector generating a sine wave voltage output a characteristic of which changes responsive to motion of said casing; and said circuitry means further including a tone oscillator, a rate oscillator and an amplifier, connected between said motion detector and said piezoelectric sound generating transducer and responsive to the output of said motion detector to cause a specific high intensity sweeping alarm signal to be emitted when the circuitry means is turned on and in the event that the casing is motionless.
