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.

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.

In some examples, a system includes a head-mounted device, a visor that includes a reflective object that is substantially transparent in a visible light spectrum and embodied at a physical surface of the visor, at least one visor attachment assembly that couples the visor to the head-mounted device; at least one optical sensor; and at least one computing device communicatively coupled to the at least one optical sensor, the at least one computing device comprising a memory and one or more computer processors that: receive, from the optical sensor, an indication of light outside of a visible light spectrum that is reflected from the reflective object; determine, based at least in part on the light outside of a visible light spectrum that is reflected from the reflective object, a position of the visor; and perform, based at least in part on the position of the visor, at least one operation.

Example apparatus, methods, circuitry, and computer program products are provided 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 of sensors to generate data associated with motion of the user at a first sampling rate.

A helmet may include: a brain wave detector configured to detect a brain wave of a user; a sound input configured to receive sound; a sound output configured to output sound; and a controller configured to, in response to detecting the brain wave of the user, compare the detected brain wave with a previously stored brain wave, to activate a dialogue mode when the detected brain wave matches the previously stored brain wave, to recognize a speech from the sound received by the sound input, to generate a dialogue speech based on the recognized speech, and to control the sound output so as to output the generated dialogue speech.

Guard padding with sensor is provided, including a cushion pad and a sensor. The cushion pad has auxetic structure and is manufactured by a 3D printing process. The cushion pad has a slot at a side thereof. The sensor manufactured by the 3D printing process is disposed in the slot. The sensor is a pressure sensor, a humidity sensor or a temperature sensor. The pressure sensor generates a pressure signal, the humidity sensor generates a humidity signal and the temperature sensor generates a temperature signal.

The present invention is directed to a helmet wearing determination system including a imaging means that is installed in a predetermined position and images a two-wheel vehicle that travels on a road; and a helmet wearing determination means that processes an image imaged by the imaging means, estimates a rider head region corresponding to a head of a person who rides on the two-wheel vehicle that travels on the road, compares image characteristics of the rider head region with image characteristics according to the head at a time when a helmet is worn or/and at a time when a helmet is not worn, and determines whether or not the rider wears the helmet.

In some examples, a system (1900) includes a hearing protector (1920); at least one position sensor; at least one sound monitoring sensor; at least one computing device configured to: receive, from the at least one sound monitoring sensor and over a time duration, indications of sound levels to which a worker is exposed; determine, from the at least one position sensor and during the time duration, that the hearing protector is not positioned at one or more ears of the worker to attenuate the sound levels; and generate, in response to the determination that at least one of the sound levels satisfies an exposure threshold during the time duration and the hearing protector is not positioned at one or more ears of the worker to attenuate the sound levels, an indication for output.

In some examples, a system includes a head-mounted device, a visor that includes a reflective object that is substantially transparent in a visible light spectrum and embodied at a physical surface of the visor, at least one visor attachment assembly that couples the visor to the head-mounted device; at least one optical sensor; and at least one computing device communicatively coupled to the at least one optical sensor, the at least one computing device comprising a memory and one or more computer processors that: receive, from the optical sensor, an indication of light outside of a visible light spectrum that is reflected from the reflective object; determine, based at least in part on the light outside of a visible light spectrum that is reflected from the reflective object, a position of the visor; and perform, based at least in part on the position of the visor, at least one operation.

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.
