A helmet assembly for a spacesuit or other protective suit is disclosed. In embodiments, the helmet assembly includes an external face shield attachable to the spacesuit and providing the spacesuit user with a forward field of view. The helmet assembly includes suit status displays hard-mounted to the external face shield at a periphery or edge of the forward field of view (e.g., upper, lower, left, right). Each suit status display includes a linear or one-dimensional array of individual light emitting diodes (LED) in communication with a suit controller of the spacesuit. Each LED array receives from the suit controller suit status data (e.g., consumables levels, suit performance, position data) communicated to the user by illuminating one or more of the individual LED units.

A surgical protection system to define a barrier between the user and the external environment. The surgical protection system comprising a helmet assembly, a hood and a transparent face shield. The helmet including a shell, a face frame coupled to the shell, a static tab, a first fastener disposed on the face frame; and a fan mounted to the shell and configured to circulate air about the user. The hood may include a first material defining an opening. The shield may be formed from flexible material and disposed within the opening of the hood. The shield may further include a tab extending from a top portion of the shield and define an opening configured to receive the static tab of the helmet to align the shield to the helmet. The first fastener disposed on the face frame may be configured to facilitate removable attachment of the shield to the helmet.

The present invention relates generally to a helmet, method and server for detecting a likelihood of an accident. According to a first aspect, the present disclosure refers to a helmet of detecting a likelihood of an accident, comprising: a sensor configured to detect a signal relating to a user wearing the helmet, the signal including information at a point in time for the user; and a processor configured to communicate with the sensor and to: determine if there is the likelihood of the accident in response to receiving the signal; generate an alert signal in response to the determination, the alert signal indicating there is the likelihood of the accident.

A method of synchronizing flashing between a plurality of marker system components mounted on a helmet includes receiving a signal from at least one global positioning satellite receiver, the signal comprising a time value. When the time value indicates illumination is needed, initiating illumination of at least one light emitting device of each the marker system components, thereby, synchronizing of the initiating of illumination to the time value for all marker system components.

A speaker device is used while being attached to a helmet, and includes a speaker unit that outputs a sound, a speaker housing that includes a back wall portion covering the speaker unit from a back side, and in which a space between a back surface of the speaker unit and the back wall portion is formed as an output space for the sound output from the back surface of the speaker unit, and a duct whose internal space is communicated with the output space and that guides, to an outside of the helmet, the sound output to the output space, in which a distance between the back surface of the speaker unit and the back wall portion is smaller than a distance of the internal space of the duct in a direction in which the duct guides the sound.

A control unit for a worker wearing personal protective equipment is presented. The control unit includes a PPE network creator that, when activated, creates a network. The control unit also includes a PPE device identifier configured to detect a first PPE associated with the worker and a second PPE associated with the worker. The first PPE has a first speaker and a first microphone. The second PPE has a second speaker and a second microphone. The control unit also comprises a PPE network joiner that facilitates the first and second PPE joining the network. The control unit also comprises a preferred configuration selector that automatically selects a preferred speaker for the worker and a preferred microphone for the worker. The preferred speaker is the first or second speaker. The preferred microphone is the first or second microphone. The control unit also comprises a network communication component that automatically communicates a first device parameter settings to the first PPE and a second device parameter settings to the second PPE. The first and second device parameter settings are based on the selected preferred speaker and microphone.
