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.

The invention relates to a protective sports helmet purposely designed for a selected group of helmet wearers from amongst a larger population of helmet wearers. A multi-step method for helmet design starts by collecting information from a population of players that may include information about the shape of a player's head and the impacts the player has sustained. This information is then processed to create player population information that is sorted to create categories. Advanced mathematical techniques are utilized to further sort these categories into player groups or data sets based on player attributes. Once the player groups are identified, another multi-step process is utilized to design optimized helmet prototype models for each player group. These optimized helmet prototype models are then further processed into complete helmet models by determining a structural design and chemical composition that is manufacturable and has mechanical properties that are substantially similar to the optimized helmet prototype model. Physical helmet prototypes are then created and tested using a unique helmet standard derived from information associated with each player group. Once the prototypes pass testing, the complete helmet models can be manufactured to create actual stock helmets or stock helmet components for future players whose characteristics and attributes place them within the selected player group.

An intelligent motorcycle helmet system includes a helmet assembly and a first control module incorporated into the helmet assembly and communicatively coupled to a set of helmet-mounted lighting components. A haptic feedback module is incorporated into the helmet assembly. A second control module is configured to be removably mounted to a motorcycle. The first control module selectively activates the helmet-mounted lighting components to reflect the state of the left and right turn signals and the brake light of the motorcycle as determined via the second control module and the lighting state sensing module. The first control module selectively actuates the haptic feedback module during operation of the motorcycle in response to at least one event associated with the motorcycle.

The present invention discloses a safety device adapted to prevent workers from going into hazardous environment, such as underground using the faulty safety device. As a safety device, typically embodied as a cap lamp, must be charged prior to each use, the device is adapted to detect when the device is removed from the charger. The device starts to blink continuously when disconnected from the charger. An automated test procedure is completed on the device. The user may also complete a manual portion of the test procedure to make the device usable. When the test procedure is completed successfully, the lamp stops blinking. If the test procedure is not successful, the lamp continues blinking to effectively prevent user from using a faulty device.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A helmet configured to be worn by a wearer that includes an outer shell, an inner liner positioned inside the outer shell, a data collection assembly that includes a first data collection member for measuring impact data, and a second data collection member for measuring vital signs data.

A personal mobility device includes a helmet, for example, when renting the personal mobility device, and can improve user safety based on an output of a sensor provided in the helmet. The personal mobility device further includes: a transceiver; a helmet storage device in which the helmet provided with at least one sensor is stored; and a controller configured to control the transceiver to be wirelessly connected to the helmet when receiving a signal indicating separation between the helmet storage device and the helmet from the helmet storage device, and to control the transceiver to transmit a signal requesting the activation of the at least one sensor to the helmet.

Rider location and acceleration sharing systems are provided herein. For instance, a system is paired with a wireless transceiver, mountable to or within headwear that outputs location data and accelerometer data associated with the user identity to a user device. Once members of the group of user devices are validated for movement together, an emergency event associated with a member of the group may be identified based on the accelerometer data or the location data, and, in response to the emergency event, emergency event data is sent to the respective other user devices, and other information is enabled to be received from any of the respective other user devices.

A head guard is provided. The head guard includes one or more sensors as part of an sensory input and communications system. The head guard wirelessly communicates data to remote computing devices for intelligent data collection.

Certain aspects of the present disclosure provide measures, including apparatus, methods, circuitry, and computer program products for use in impact detection. Example apparatus comprises a plurality of sensors. The apparatus is configured to determine whether a user is wearing an item in which the apparatus is comprised, and in response to a positive determination, operate the apparatus in an active operating mode. The active operating mode comprises operating one or more sensors in the plurality to generate data associated with motion of the user at a first sampling rate.
