Abstract: A suspension band assembly to be used to support a hard hat on a head of a user. The suspension band assembly includes a primary support loop to receive the head of the user therein. An electronic peripheral is fixedly secured to the primary support loop. An attachment strap extends out from the primary support loop to a strap distal end. An anchor is fixedly secured to the strap distal end for securing the attachment strap to the hard hat. An electrical anchor contact is fixedly secured to the anchor to provide an electrical connection between the hard hat and the electronic peripheral located on the primary support loop.

Abstract: A method for alerting a user of a first portable communications assembly that another user of a second portable communications assembly is within a predetermined distance includes the step of receiving a distance signal transmitted by the transmitter in the second portable communications assembly. A distance between the first and second portable communications assemblies based on the distance signal is calculated based on the strength of the distance signal or based on a time stamp embedded in the distance signal. An alert is emitted when the distance calculated between the first and second portable communications assemblies is less than the predetermined distance.

Abstract: A conversion assembly is secured to a hard hat having a protective dome cover defining a peripheral rim, and a visor. The conversion assembly includes a compartment and a plurality of electronic circuits housed within the compartment. A mechanical connector removably secures the compartment to the protective dome cover of the hard hat.

Abstract: A conversion assembly is secured to a hard hat having a protective dome cover and a visor. The conversion assembly includes a plurality of compartment housings operatively secured together. A plurality of electronic circuits is housed within the plurality of compartment housings. A mechanical connector removably secures the conversion assembly to the hard hat when functions performed by the plurality of electronic circuits are required for a person wearing the hard hat. The invention provides enhanced functionality to an already existing hard hat, helmet or other protective head gear.

Abstract: A hard hat assembly is designed to be worn on a head of a user. The hard hat assembly includes a helmet shaped to cover an upper portion of the head of the user. The helmet defines a primary opening to receive the head therein. The helmet also defines a periphery about the primary opening. A brim extends outwardly from the helmet adjacent the periphery to a brim outer edge. A brim panel is removably securable to the brim and, along with the brim, creates one or more compartments between the brim and the brim panel. An electrical circuit is fixedly secured within the compartments.

Abstract: A geo-localization device and methodology use a plurality of wireless localization technologies, predictive methods and filtering to deliver accurate and reliable 3-dimensional positioning data for static and moving objects both outdoor and indoor.

Abstract: A method calibrates a sensor for a defined parameter using a calibration station adapted to receive the sensor while it is secured to a wearable device. The calibration station includes a device to close the space surrounding the sensor to control the space. A quantity of an element being measured/calibrated is injected into the space. The quantity of the element is then measured by the sensor. A measured signal is transmitted to the calibration station. The measured signal is compared to a predetermined level. The method identifies when the measured signal differs from the predetermined level by a threshold amount and indicates or adjusts the sensor, depending on the application.

Abstract: A biometric sensor assembly measures biometric data of a wearer of a hardhat. The biometric sensor assembly includes a suspension harness to be removably secured to the hardhat. A biometric sensor is attached to the suspension harness in a way that allows direct or indirect contact with the wearer to enable measurement of the biometric data. The biometric sensor assembly also includes an electrical connection of the biometric sensor and the hardhat for data and power transmission.

Abstract: A communications assembly includes a central processing unit and a plurality of hardhat assemblies. The central processing unit transmits central signals and receives remote communications from the hardhat assemblies. The hardhat assemblies are operatively connected to the central processing unit in order to transmit the remote communications and receive the central communications. A communications hub is operatively connected between the central processing unit and each of the hardhat assemblies to control independent communication between the central processing unit and the hardhat assemblies. The central processing unit includes an incident identification module for receiving the remote communications and for identifying a portion of the remote communications from a portion of the hardhat assemblies as indicating a situation requiring a communication to be sent to the portion of the hardhat assemblies. The portion may include one or more than one hardhat assembly.
