Abstract
Various embodiments of safety headwear are provided. The safety headwear includes one or more of a hard hat, such as a safety helmet, and a respirator. The safety headwear monitors one or more conditions, such as biometric and/or atmospheric conditions. The safety headwear analyzes the results of the monitoring to determine whether to generate an alarm to the wearer of the safety headwear.
Claims20
A hard hat comprising:
- an outer shell;
- an outer surface of the outer shell;
- an inner surface of the outer shell, the inner surface defining a cavity configured to receive a head of a person wearing the hard hat;
- a biometric measuring device supported by the outer shell and configured to measure a biometric characteristic of the person wearing the hard hat;
- and
- an environmental measuring device supported by the outer shell and configured to measure an atmospheric condition.
3 more elements
A respirator comprising:
- a body;
- a gasket coupled to the body and configured to engage against a face of a person wearing the respirator to define a secured area between the respirator and the face of the person;
- a filter coupled to the body and configured to remove particulates from air passing through the filter to the secured area;
- an air pressure measuring device supported by the body and configured to measure an air pressure measurement within the secured area and generate a signal indicating the measured air pressure measurement;
- and
- a monitoring unit supported by the body and configured to receive the signal from the air pressure measuring device indicating the air pressure measurement, the monitoring unit configured to generate an alarm in response to detecting an error condition based on analyzing the air pressure measurement.
3 more elements
A hard hat system comprising:
- a respirator comprising:
- a body;
- a gasket coupled to the body and configured to engage against a face of a person wearing the respirator to define a secured area between the respirator and the face of the person;
- a filter coupled to the body and configured to remove particulates from air passing through the filter to the secured area;
- and
- an air pressure measuring device supported by the body and configured to generate a first signal indicating an air pressure measurement;
- and
- a hard hat comprising:
- an outer shell;
- an inner surface of the outer shell, the inner surface defining a cavity configured to receive a head of the person wearing the hard hat and the respirator;
- a biometric measuring device supported by the outer shell, the biometric measuring device configured to generate a second signal indicating a measurement of a biometric characteristic of the person wearing the hard hat;
- and
- a monitoring unit supported by the outer shell and communicably coupled to both the air pressure measuring device and the biometric measuring device, the monitoring unit configured to receive and analyze the first signal and the second signal, the monitoring unit configured to generate a first alarm in response to analyzing one or more of the first signal and the second signal.
