Abstract
An apparatus is disclosed having a sensor configured to measure a biological parameter of a diver and transmit a sensor signal. A controller is configured to determine that the biological parameter value correlated to the sensor signal is anomalous and responsively issue a rescue deployment signal to a buoyancy valve assembly. The buoyancy valve assembly has an inlet port connectable to a source of pressurized gas and an outlet port connectable to a buoyancy control bladder. The buoyancy valve assembly configured to receive the rescue deployment signal and responsively supply pressurized gas from the inlet port to the outlet port and buoyancy bladder, whereby the diver may ascend the water surface, even if disabled.

An apparatus for a diver comprising:
- a sensor configured to measure a biological parameter of the diver and transmit a sensor signal correlated to a biological parameter value;
- a controller configured to:
- receive the sensor signal, and
- determine the biological parameter value correlated to the sensor signal is anomalous and responsively issue a rescue deployment signal;
- and
- a buoyancy valve assembly having:
- an inlet port connectable to a source of pressurized gas,
- an outlet port connectable to a buoyancy bladder, and
- a passageway between the inlet port and the outlet port,
- the buoyancy valve assembly configured to receive the rescue deployment signal and responsively open the passageway between the inlet port and the outlet port.
An apparatus for a diver comprising:
- a sensor configured to measure a biological parameter of the diver and transmit a sensor signal correlated to a biological parameter value;
- a diver-activatable device configured to provide a stop signal upon being activated by the diver;
- a controller configured to:
- receive the sensor signal,
- determine the biological parameter value correlated to the sensor signal is anomalous and responsively both issue a warning alarm and begin measuring a time interval,
- detect the stop signal during the time interval, and
- issue a rescue deployment signal when no stop signal detected during the time interval;
- and
- a buoyancy valve assembly having:
- an inlet port connectable to a source of pressurized gas,
- an outlet port connectable to a buoyancy bladder, and
- a passageway between the inlet port and the outlet port,
- the buoyancy valve assembly configured to receive the rescue deployment signal and responsively open the passageway between the inlet port and the outlet port.
