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

An informatics system that can be head-worn under a helmet and used to provide a wearer's vital statistics and other information to a remote monitoring station, for example in connection with pre-hospital emergency care.

Disclosed herein is an apparatus for preventing fogging in a head worn apparatus, in accordance with some embodiments. Further, the head worn apparatus covers a portion of a head of a user. Further, the apparatus comprises an elongated body, an attachment mechanism, and a fan assembly. Further, the elongated body extends from a first end of a first portion to a second end of a second portion. Further, the elongated body is curved around an axis perpendicular to the elongated body making the first portion substantially perpendicular to the second portion. Further, the elongated body tapers from the first end towards the second end. Further, the attachment mechanism is configured to be coupled with a portion of the head worn apparatus. Further, the at least one fan assembly is configured for circulating airflow in the head worn apparatus.

Systems and methods for platform occupancy detection on an aerial device are described. An aerial platform may be provided for the aerial device. A worker may perform operations in the aerial platform and connect to an interlock system thereof. The worker may have an associated transmitter configured to transmit a signal. A first receiver and a second receiver may be disposed on the aerial platform to receive the signal. Based on the time difference between receiving the signal at the first receiver and receiving the signal at the second receiver, the position of the transmitter may be triangulated. If the transmitter is determined to be within the aerial platform and the worker is not connected to the interlock system, preventive actions may be taken before operation of the aerial platform is permitted.

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 helmet includes a non-contact sensor for a living body, a cap body, and a headband attached to an inner side of the cap body. The headband is provided with a first projection and a second projection on a surface facing a front head portion (FD) of the cap body. The non-contact sensor for the living body includes a first housing having a first surface and a second surface opposing the first surface, a first claw portion provided on the first surface, and a second claw portion provided on the second surface. The first claw portion is brought into contact with and fixed to the first projection, and the second claw portion is brought into contact with and fixed to the second projection.

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.

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 method of using an augmented audio enhanced perception system, comprising: tracking at least one object with at least one helmet mounted sensing unit; processing at least one of the at least one tracked object and an ambient sound by a processing unit; and, providing at least one of a synthesized audio signal and a processed ambient sound to a first user of the system using an audio interface unit, to provide information concerning the at least one object to the first user.
