An augmented-reality system is combined with a surveying system to make measurement and/or layout at a construction site more efficient. A reflector can be mounted to a wearable device having an augmented-reality system. A total station can be used to track a reflector, and truth can be transferred to the wearable device while an obstruction is between the total station and the reflector. Further, a target can be used to orient a local map of a wearable device to an environment based on a distance between the target and the wearable device.

An adaptive lighting system for even illumination is provided. In an embodiment, multiple lamps illuminate light in different areas or zones of the surroundings. These lamps modulate their light output in a known (but imperceptible) pattern. One or more light detectors detects light from the surroundings. Light sourced from each lamp is disambiguated and one or more light time-of-flight delays are calculated for each lamp-light detector pair. Based on these calculated delays, illumination levels of the lights are adjusted so as to produce even illumination.

An impact reducing headgear is disclosed which utilizes dynamically responsive materials which undergo physical changes during exposure to impact forces, such that physical changes or phase changes absorb energy. The helmet may be constructed with a dual shell structure and a bladder, where the dynamically responsive materials may be contained. An embodiment for a comfortable fit which remains tight to the wearer's head is disclosed.

A system for providing safety assistance in a vehicle. The system includes a helmet and a first plurality of sensors in the helmet. The system further includes control circuitry that captures a first plurality of signals from the first plurality of sensors in the helmet. The first plurality of signals indicates first motion information corresponding to the helmet. The control circuitry further controls one of an inflation element or a hardening element disposed in a wearable garment based on a determination that the first motion information corresponding to the helmet exceeds a first predefined threshold.

An exemplary illuminated hard hat for providing visibility to workers is presented. The illuminated hard hat allows for the Illumination of the hard hat. Since, the illumination come from inside of the hard hat there no distracting lights to the face. The illuminated hard hat is lightweight and cost effective. The illuminated hard hat further protects workers from injury while meeting OSHA requirements required by law. The illuminated hard hat is useful for construction workers, road workers, mountain climbers as well as anyone who desires to wear a hard hat. While the illuminated hard hat is intended for hard hats, it can also be adapted to be used in any kind of hat worn by people.

A safety helmet, in particular a safety helmet for drivers of single-track motorcycles, is provided. The safety helmet includes at least one movable aerodynamic stabilizing element and at least one sensor element for detecting one or more current driving state variables. The aerodynamic stabilizing element is controlled depending on at least one current driving state variable detected by the sensor element. An actuator element for moving the aerodynamic stabilizing element may be provided, and may be controlled by a control unit depending on at least one current driving state variable detected by the sensor element. One or more of the sensor element, actuator element and the controller may be supplied with electrical energy from an energy supply unit.

A helmet/hood assembly includes a housing, a support ring subassembly configured to hold the assembly on a human head, a face shield, and a flexible hood attached to the housing and to the face shield, with the assembly being received, stored, used, and disposed as a single unit. The support ring subassembly pivots on the housing between a position suitable for shipping and storing the assembly and a position in which the assembly is worn. An accessory light powered by a battery may be held in place on the housing by magnetic attraction through the hood.

Systems, methods, and devices for protecting a user head are provided. In one example, a computer-implemented method can comprise receiving, by a processor operatively coupled to a helmet device, helmet data comprising at least one of statistical data, statistical models, or natural intelligence algorithms. The computer-implemented method can also comprise inflating, by a gas delivery system of the helmet device, a pressure chamber element of the helmet device based on the helmet data. Furthermore, the computer-implemented method can comprise scanning, by a sensor system of the helmet device, surrounding environments of the helmet device for object data.

The invention relates to a multi-step method with a number of processes and sub-processes that interact to allow for the selection, design and/or manufacture of a protective sports helmet for a specific player, or a recreational sports helmet for a specific person wearing the helmet. Once the desired protective sports helmet or recreational sports helmet is selected, information is collected from the individual player or wearer regarding the shape of his/her head and information about the impacts he/she has received while participating in the sport or activity. The collected information is processed to develop a bespoke energy attenuation assembly for use in the protective helmet. The energy attenuation assembly includes at least one energy attenuation member with a unique structural makeup and/or chemical composition. The energy attenuation assembly is purposely engineered to improve comfort and fit, as well as how the helmet responds when an impact or series of impacts are received by the helmet.

The invention relates to a protective helmet, in particular a protective motorcycle helmet, comprising an outer shell (1) for distributing impact forces, a battery socket (2), which is firmly connected to the outer shell (1), for detachably accommodating a battery (3), and a line assembly (4), which is electrically connected to the battery socket (2), for supplying electricity by means of the accommodated battery (3) to an electric apparatus (5) which is mechanically coupled to the outer shell (1).
