Various embodiments relating to methods for evaluating injury mitigation performance of helmets that are used for contact sports (e.g., rugby) are described. In one embodiment, a method for evaluating injury mitigation performance of a helmet includes applying first, second, and third impact configurations to a first helmet. The method further includes generating acceleration and velocity data based on impacts that occur as part of the three impact configurations. The method further includes determining injury risk values based on the generated acceleration and velocity data. The method also includes determining an overall risk metric based on the injury risk values and exposure values.

A head-mounted device capable of more highly accurately measuring the physical conditions of a wearer as a worker that are necessary for estimating the possibility of heat stroke is provided. A head-mounted device includes an outer shell; a first channel as a gap between a head of a wearer and the outer shell; a second channel provided in the outer shell and connected to the first channel; a fan configured to send air from one of the first channel and the second channel to the other; a salinity sensor configured to measure salt concentration of sweat of the wearer; a first humidity sensor configured to measure an absolute humidity of intake air entering one of the first channel and the second channel; and a second humidity sensor configured to measure an absolute humidity of exhaust air exiting from the other of the first channel and the second channel.

An aircraft having an augmented reality flight control system integrated with and operable from the pilot seat and an associated pilot headgear unit, wherein the flight control system is supplemented by flight-assisting artificial intelligence and geo-location systems is presented. The present disclosure includes an augmented reality flight control system incorporating real-world objects with virtual elements to provide relevant data to a pilot during aircraft flight. A translucent substrate is disposed in the pilot's field of view such that the pilot can see therethrough, and observe virtual elements displayed on the substrate. The system includes a headgear that is worn by the pilot. A flight assistance module is configured to receive data related to the aircraft and provide predictive assistance to the pilot during flight based on the received data based in part on a pilot profile having preferences related to the pilot.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A system for controlling a vehicle includes a programming device comprising an application for programming vehicle function settings of a vehicle. The programming device has a transmitter communicating the vehicle function settings of the vehicle. A vehicle receiver is disposed within the vehicle. The vehicle receiver receives the vehicle function settings. A vehicle is controller disposed within the vehicle. A helmet generates a helmet movement signal in response to sensing movement of the helmet. The helmet communicates a helmet identifier to the vehicle controller through the receiver in response to the helmet movement signal. The vehicle controller controls a vehicle function in response to the vehicle function settings.

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.

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.

The present invention achieves technical advantages as a vehicle cabin, comprising a floor system formed of removable and reconfigurable floor segments extending from a vehicle frame, and a ceiling system formed of removable and reconfigurable ceiling segments disposed in the ceiling of the vehicle cabin. Floor segments that can be positioned to form a floor channel, therebetween. A fixture interface adapted to releasably secure a fixture to the floor system. The fixture can be slidably repositioned within the vehicle along the floor channel. One of the ceiling segments includes one or more of a lighting module, a ventilation outlet, a ventilation inlet, a display screen, or a touch control panel. The ceiling segments can be hexagonal.

Eyewear apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as EOG and ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.
