A self-retracting lanyard including a main body and a retractable line. The retractable line is coupled to the main body so as to be extendible and retractable relative to the main body and to be restricted from extending relative to the main body in response to a user of the self-retracting lanyard falling. The self-retracting lanyard further includes a manual control operable by the user to initiate controlled descent of the retractable line relative to the main body. The manual control may be operable by the user to deliver a fluid (e.g. compressed gas) from a fluid supply disposed in a housing of the manual control to an actuator of the main body to initiate controlled descent. Solar panel(s) may be disposed on the main body. When the retractable line is retracted, the housing may dock with and be charged by a solar powered charger disposed on the main body.

A method, system and computer program product are provided for implementing route generation with augmented reality. A crowd or event is analyzed and escape routes are intelligently distributed by attendee profile type or ability. Augmented Reality (AR) projections are used representing different subsets of an event population to convey the profile-specific escape routes for people to follow. The AR behavior is changed as an event situation changes.

A body belt for use by linemen and others engaged in operations on poles or similar structures having a secondary set of D-rings, typically disposed slightly rearward of the primary D-rings on the belt or an auxiliary belt or attachment above or below the primary D-ring of the belt. The secondary D-rings which may differ in size from the primary D-rings, allow a wearer to separate devices that are normally attached to the primary D-rings. This allows less crowding of the primary D-rings, thereby making detachment and reattachment of one or more ancillary safety devices from the body belt as a lineman encounters an obstacle during his or her work on a pole or other elevated structure, thereby improving safety. An add-on D-ring assembly is provided for retrofitting body belts of the prior art. In another embodiment of the invention, an auxiliary body belt is detachably connected to the primary body belt, the auxiliary body belt having its own set of D-rings. Rather than providing all four D-rings in a common plane, as described above, this embodiment provides one plane for the first set of D-rings (on the primary body belt) and a second, parallel plane for the second set of D-rings (on the auxiliary body belt).

Embodiments of the present invention provide a method, computer program product, and a computer system for automated deployment of autonomous devices performing localized environment altering actions. A set of weather conditions for a region is received. Based on the weather conditions predicting the weather in the region is likely to have a negative effect on at least one living organism in the region. Then dispatching, one or more autonomous devices to the region, wherein the one or more autonomous devices comprise a set of sensors and at least one temperature altering element. The autonomous devices is directed to a first location of the first living organism, based, at least in part on a set of data received from the set of sensors. The autonomous devices is directed to alleviate at least a portion of the negative effect of the temperature to the first living organism.

A portable device for inflating an inflatable bag (60) comprises at least one inlet (46), for forming a fluid connection to a gas source. The gas source is attached or attachable to the inlet. The device further comprises an air intake chamber (32) which has an opening allowing atmospheric air to be admitted and an outlet intended to be connected to the bag to be inflated. The gas source comprises a first and at least a different second gas component. The first component is stored at least partially in liquid form; preferably, the first component is carbon dioxide. The gas source contains at least 10%, preferably more than 30% and most preferably more than 60% of the first component. The second component is gaseous or supercritical at a temperature of 243K and up to a pressure of 200 bar, preferably, the second component has a critical temperature below 243K.

Apparatus and associated methods relate to determining a fit-quality metric for a mask/face combination based upon a calculated dead-space volume between a virtual mask and a virtual face virtually aligned so as to create an integrity seal circumscribing a mouth and nose region. In an illustrative embodiment, an interactive virtual fitting system may receive a three-dimensional (3D) virtual face associated with a person. The system may retrieve 3D models of various respirators selected by user determined criteria. The system may then compute a fit-quality metric for each of the retrieved 3D models. The potential wearer may then be presented with the metrics for review. The potential wearer may select a respirator based upon these computed metrics. A virtual fitting of many respirators may advantageously reduce the time needed for selecting a properly fitting respirator while simultaneously ensuring that the selected respirator may be comfortable and well fitting.

A system, management device, SCBA and wearable device are provided. In one or more embodiments, a wearable device for use with a self-contained breathing apparatus (SCBA) is provided. The device includes device processing circuitry configured to: determine a wireless personal accountability report (PAR) signal has been received, and transition into an alarm state based on the received wireless PAR signal. The alarm state configured to trigger at least one notification while in the alarm state where the triggering of at least one notification is configured to recur until an indication is received.
