Abstract
A depth selector or current depth provider for use by a variable speed air system. As a depth selector it is preferably in the form of a rotary switch on the user interface for the air system. The rotary switch can have 3 positions for maximum depth selections, such as, without limitation 15, 25, and 65 feet. Other depth values and number of depth selections provided can be used and all are considered within the scope of the disclosure. A microcontroller of the system reads the voltage from the voltage divider created by the rotary switch selection to determine which position the rotary switch is in. The microcontroller uses this information to set the upper and lower pressure limits for the dive.
Claims10
A depth selector device integrated into a variable speed surface supplied air system, the air system having a user interface, comprising:
- a rotary switch provided on the user interface and having a plurality of positions;
- a voltage divider in connection with the rotary switch, the voltage divider having a plurality of resistors with each resistor associated with a corresponding one position from the plurality of positions of the rotary switch;
- a microcontroller in communication with the voltage divider for reading a current voltage from the voltage divider based on a position selected for the rotary switch, the microprocessor is configured to use the current voltage information to set an upper pressure limit and a lower pressure limit for a dive using the variable speed surface supplied air system.
A depth selector device for use with a variable speed surface supplied air system, the air system having a compressor, comprising:
- a depth sensor embedded or disposed at or with a diver during an underwater activity involving the variable speed surface supplied air system;
- and
- a microcontroller in communication with the depth sensor, wherein the depth sensor sends one or more signals to the microcontroller and the microcontroller is configured to use the information or data represented in the one or more signals received from the depth sensor to automatically update pressure limits for the compressor throughout the underwater activity to adjust for a current depth and depth changes of the diver in real-time.
A depth selector device integrated into a variable speed surface supplied air system, comprising:
- a manually controlled input device for selecting one from a plurality of diver depth choices;
- and
- a microcontroller in communication with the manually controlled input device, the microprocessor configured or programmed to use the selected diver depth information to set an upper pressure limit and a lower pressure limit for a diver's dive using the variable speed surface supplied air system.
