The present invention discloses a method for interlocking a shared bicycle and an intelligent safety helmet, and the method comprises the following steps: (1) providing an electronic frame lock and an intelligent safety helmet for using cooperatively on a shared bicycle respectively, interlocking both of them when the shared bicycle is parked; (2) checking the current state information of an electric lock and a safety helmet lock simultaneously when a user uses the mobile intelligent terminal to scan the shared bicycle; (3) unlocking of the electric lock and the safety helmet lock when the verification is passed; (4) wearing an intelligent safety helmet before using the bicycle; (5) beginning to record the trip information by the intelligent helmet after the user puts on the intelligent safety helmet; (6) stopping the voice broadcast function and terminating the recording of the trip information when the state information of the electronic frame lock and the safety helmet lock which is checked shows that the electronic frame lock and the safety helmet lock are locked, after the user terminates the using of the bike. The invention also discloses an interlocking device for a shared bicycle and an intelligent safety helmet implementing the above-mentioned method, which makes that the bicycle and the intelligent safety helmet are always in a state that they are used in cooperation with each other.

Helmet-mounted systems (100) that may include lighting systems (102) and solar-powered battery systems (112), automated controls (116), and/or integrated sensors (104) that result in an automated and fully integrated systems that do not require user-initiated recharging of batteries or require a user to manually turn the components of the system on and off.

A protective helmet (200) adapted for the external display of controllably selectable images, comprising: an outer portion (202); and a display module (212) comprising a flexible electronic display screen (214); wherein the outer portion comprises a recess (206) configured to receive the display module; and wherein the display module is positioned within the recess such that an outer surface (213) of the display module continues a profile of the outer portion.

A safety headwear monitoring system is provided. The safety headwear monitoring system comprising: a sensor configured to detect a status parameter, wherein the status parameter indicates whether an object is located within a selected distance of the sensor; a transmission device in electronic communication with the sensor and configured to receive the status parameter from the sensor; and an application installed on a user device in wireless communication with the transmission device; wherein the transmission device is configured to transmit the status parameter to the application.

An audio control system of a vehicle includes a sound control module configured to determine N magnitudes for outputting a predetermined sound at N predetermined harmonics of a base frequency, respectively. N is an integer greater than one. An adjustment module is configured to determine N magnitude adjustments for the N predetermined harmonics, respectively, based on a helmet worn by a driver of the vehicle. The sound control module is further configured to determine N adjusted magnitudes for the N predetermined harmonics based on: the N magnitudes for the N predetermined harmonics, respectively; and the N magnitude adjustments for the N predetermined harmonics, respectively. An audio driver module is configured to, based on the N adjusted magnitudes, apply power to at least one speaker of the vehicle and output the predetermined sound at the N predetermined harmonics of the base frequency, respectively.

The present disclosure includes an article of PPE. The device includes a first sensor that detects whether the article of PPE is being worn by a user, a processing module and a communications module. The processing module includes a clock that measures the length of time that the article of PPE is being worn by the user, and memory for storage of usage data, wherein usage data includes the length of time the article of PPE has been worn by the user. The communications module is for wirelessly transmitting stored usage data to a device separate from the article of PPE.

A safety headwear monitoring system is provided. The safety headwear monitoring system comprising: a sensor configured to detect a status parameter, wherein the status parameter indicates whether an object is located within a selected distance of the sensor; a transmission device in electronic communication with the sensor and configured to receive the status parameter from the sensor; and an application installed on a user device in wireless communication with the transmission device; wherein the transmission device is configured to transmit the status parameter to the application.

A safety helmet for enhancing visibility to road users. The safety helmet has a plurality of lights which are operatively connected to a power supply; at least one motion sensor which detects a behavioural characteristic of the cyclist and provides input signals to a controller, the controller operates in accordance with an algorithm whereby the signals are processed to determine appropriate timing of activation of the lights, in dependence upon the behavioural characteristic detected; and wherein switching signals from the controller switch on the lights to indicate actual or intended direction of travel

The present disclosure includes a retrofit sensor module for use with a protective head top with a helmet and a visor. The sensor module includes a sensor housing and an attachment mechanism. The sensor housing encloses a head presence sensor to sense when the protective head top is being worn. The sensor housing also encloses a position sensor to sense the position of the visor relative to the helmet. The retrofit sensor module further comprises an attachment mechanism secured to the housing. The attachment mechanism mates with a first hinge component of a hinge assembly in the protective head top to removably install the sensor module into the protective head top, wherein the hinge assembly allows the visor to move relative to the helmet.

A helmet comprising a shell to at least partially protect the head of a user, and a camcorder integrated into the helmet, provided with at least one lens arranged to view at least a part of the environment surrounding the helmet, the camcorder being provided with a recording activation/deactivation switch, wherein the said switch is positioned on the helmet so as to activate the camcorder recording when the helmet is put on by the user.
