Abstract: Pressurized air apparatuses and associated methods are described. According to one aspect, a pressurized air apparatus includes an air input configured to receive pressurized air, a pressure sensor configured to receive the pressurized air from the air input, measure a plurality of different pressures of the pressurized air at a plurality of moments in time, and generate a plurality of signals that are indicative of the different pressures of the pressurized air, processing circuitry configured to receive the signals from the pressure sensor, and process the signals to select one of the signals and disregard others of the signals, and a user interface configured to communicate a value indicative of the pressure of the pressurized air that corresponds to the selected one of the signals to an operator of the pressurized air apparatus.

Abstract: Inflatable device pressure gauge apparatus and methods are described. According to one aspect, an inflatable device pressure gauge apparatus includes a housing, an attachment mechanism configured to attach the pressure gauge apparatus to an inflatable device which comprises an air chamber which is configured to be inflated to an increased pressure above atmospheric pressure during use of the inflatable device, a pressure sensor coupled with the housing and configured to sense pressurized air from the air chamber of the inflatable device and to output a signal corresponding to an air pressure within the air chamber, a processor configured to process the signal from the pressure sensor and to control generation of a user perceptible emission regarding the air pressure of the air chamber as a result of the processing of the signal, and a power source coupled with the housing and configured to provide electrical energy to the processor.
