Flow sensor

A method for determining personal protective equipment (PPE) comfort for an individual wearer includes defining a first anatomical shape data representative of an anatomical area of the individual wearer prior to donning a PPE, a second anatomical shape data representative of the anatomical area of the individual wearer after donning the PPE, and comparing the first anatomical shape data with the second anatomical shape data. The method further includes determining a soft skin tissue deformation at a plurality of predetermined anatomical positions based on the comparison between the first anatomical shape data and the second anatomical shape data, and determining a displacement comfort threshold (CTd) value based on the soft skin tissue deformation. The method also includes determining a pressure pain threshold (PPT) value, and determining a comfort metric based on the PPT values and the CTd values. The method also includes generating a notification corresponding to the comfort metric.

System and method for determining personal protective equipment comfort

An ethylene oxide sterilization sensor, and method of use, wherein the sensor includes: a heat-shrinkable film; an acid-functional porous sorbent in thermal contact with the heat-shrinkable film; and an acid having a boiling point above 120° C. and a pKa of no greater than 2.5, wherein the acid is impregnated in or covalently attached to the porous sorbent.

Ethylene oxide sterilization sensor including acid-functional sorbent and method of use

There is provided a fit testing method comprising: providing a respirator donned by a wearer; providing a sensor in electrical communication with a sensing element, where the sensor is configured to monitor a particulate concentration parameter of a gas space within the respirator, and a second particulate concentration parameter of a gas space outside the respirator, where the sensor is attached to the respirator such that the respirator such that the weight of the sensor is supported by the respirator; and providing a reader configured to communicate with the sensor, where the reader is configured to provide a respirator fit parameter based on a comparison of the particulate concentration within the respirator to the particulate concentration parameter outside the respirator.

Fit-test method for respirator with sensing system

A system includes a respirator, a sensor including a sensing element, and a reader configured to be in wireless communication with the sensor. The sensor is positioned substantially within an interior gas space of the respirator.

Sensing system for respirator

Flexible electrical connectors are provided to electrically connect electronic devices. The flexible electrical connector includes a removable adhesive tape strip having an adhesive surface thereof and an electrically conductive trace disposed on the adhesive tape strip. The flexible electrical connector engages an electronic device to form an electrical contact where the adhesive tape strip has an adhesive surface removably adhesively bonded to the substrate of the electronic device to at least partially cover the electrical contact.

Removable electrical connectors and devices

A ring-shaped cushion for a hearing protector or audio headset. The cushion has a circumferential contact pad for sealing on a wearer's head and an attachment for sealing with an earmuff. The cushion further has a sound insulation tube that inwardly defines an inner space. The sound insulation tube extends between the contact pad and the attachment. The cushion has a ventilation passage that extends entirely through the cushion between an inlet opening in the contact pad and an area outside of the inner space. The cushion may further include one or more physiological sensors to monitor the health of a wearer.

A method of fit testing includes providing a respirator; providing a sensor having a sensing element removably positioned substantially within an interior gas space of the respirator; providing a reader configured to be in wireless communication with the sensor; positioning the respirator over a mouth and a nose of a user while the sensor is positioned substantially within an interior gas space of the respirator; and observing respirator fit assessment data communicated from the sensor to the reader.

A sensing element includes a substrate including an electrically non-conductive surface, at least one high surface energy region, and an electrode pair structure disposed on the electrically non-conductive surface. The electrode pair structure includes at least one pair of electrodes having a gap therebetween. At least one of the electrodes is at least partially within the at least one high surface energy region. The sensing element is configured to sense fluid-soluble particulate matter.
