Abstract:
In some examples, a system includes an article of personal protective equipment (PPE) that includes a communication component; an industrial controller device that is configured to control an industrial device and includes a communication component; and a computing device communicatively coupled to the article of PPE and the industrial controller device, wherein the computing device is configured to: receive PPE data from the article of PPE and industrial controller data from the industrial controller device; determine, based at least in part on a set of the PPE data that temporally corresponds to a set of the industrial controller data, an occurrence of a safety event; and perform, based at least in part on the determination of the safety event, at least one operation.
Abstract:
An exposure-indicating supplied air respirator system comprises a head top, a clean air supply source and a portable personal communication hub. The head top comprises a visor that is sized to fit over at least a user's nose and mouth, a position sensor secured to the head top, and a head top communication module. The clean air supply source is connected to the head top that supplies clean air to the interior of the head top. The position sensor detects whether the visor is in a closed position or in an open position and the head top communication module communicates the visor position to the personal communication hub. If the personal communication hub receives a signal indicating the presence of a hazard, and if the visor is in an open position, an alert is generated.
Abstract:
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.
Abstract:
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.
Abstract:
A breathing apparatus includes a blower unit including a blower. The breathing apparatus further includes a battery pack including at least one electrochemical cell. The breathing apparatus further includes an adaptor including an adaptor housing physically connected to the blower unit and the battery pack. The adaptor further includes electrical contacts that engages with corresponding electrical terminals of the blower unit and the battery pack, such that the blower is electrically coupled to the electrochemical cell. The adaptor further includes at least one communication interface for receiving data from at least one of the blower unit and the battery pack, and transmitting data to an external device.
Abstract:
A system includes a negative pressure reusable respirator configured to be worn by a worker and to cover at least a mouth and a nose of the worker, a sensor configured to generate sensor data indicative of a characteristic of air within a work environment, and at least one computing device. The negative pressure reusable respirator includes at least one contaminant capture device configured to remove contaminants from air as the air is drawn through the contaminant capture device when the worker inhales. The at least one contaminant capture device is configured to be removable from the negative pressure reusable respirator. The at least one computing device configured to determine whether the at least one contaminant capture device is due for replacement, and perform one or more actions in response to determining the at least one contaminant capture device is due for replacement.
Abstract:
In some examples, a system includes: at least one light capture device; an article of personal protective equipment (PPE) that includes a plurality of retroreflective elements embodied on a surface of the article of PPE in a spatially defined arrangement, each retroreflective element of the plurality of retroreflective elements having at least two different retroreflective properties; a computing device communicatively coupled to the at least one light capture device, wherein the computing device is configured to: receive, from the at least one light capture device, retroreflected light that indicates at least two different retroreflective properties of at least one retroreflective element of the plurality of retroreflective elements; determine, based at least in part on each of the at least two different retroreflective properties, a safety event; and perform at least one operation based at least in part on the safety event.
Abstract:
A filter cartridge for a respirator includes an RFID chip encoding a digital change management policy (DCMP) indicating a useful lifespan of the cartridge, so that the cartridge may be replaced at the end of the useful lifespan. In some examples, a system includes a respirator comprising a facepiece and an air blower; a removable contaminant capture cartridge installed within the respirator and configured to remove contaminants from the air as the air passes through the contaminant capture cartridge, wherein the contaminant capture cartridge comprises a radio frequency identification (RFID) chip encoding a digital change management policy (DCMP) indicating a useful lifespan of the contaminant capture cartridge; and a computing device configured to read the DCMP from the RFID chip or write the DCMP to the RFID chip.
