Impact indicators which include an impact registering structure are provided for a package. The impact registering structure registers a location and an elapsed time of an impact of excessive force on the package. The structure includes a first region, a second region, and a barrier film. The first region contains a first element, and the second region contains a second element. The first and second elements are selected to register the location and the elapsed time of the impact when coming in contact. The barrier film separates the first and second regions, and is calibrated to rupture with a specified impact force. Once ruptured, the first element and the second element contact, in part, to provide a location indication of the rupture in the barrier film and a time elapsed indication indicative of the elapsed time from the rupture in the barrier film.

A lone worker system for performing a safety check is provided. The lone worker system includes a mobile device. The mobile device includes a memory storing a safety check application thereon and a processor. The processor is coupled to the memory and executes the safety check application. The processor initiates the safety check application with respect to the service call. The safety check application executes a use-case safety monitoring of the mobile device with respect to a service call to implement the safety check. The use-case safety monitoring detects an emergency situation with respect to a connectivity of the mobile device to a server, an activity of the mobile device, and a motion of the mobile device.

Impact or acceleration sensor, which contains a liquid droplet and is designed such that the position and/or distribution of the liquid indicates whether an impact or any other acceleration of a predetermined minimum magnitude has occurred, includes: first and second foils, a cavity disposed between the foil faces of the foils and at least one retaining structure disposed on the foil face of the first and/or second foil and functions to maintain the liquid in a predetermined first sub-volume of the cavity. The retaining structure is a region of the first and/or second foil formed as a local elevation, depression or irregularity of the foil face, which forms a passable barrier for the wetting and/or contacting of the first and/or second foil by the liquid and defines an area piece of the foil face of the first and/or second foil corresponding to the first sub-volume.

Shock indicator device for a watch, internal to the watch, including a structure, to which is fixed an inertia block by means of at least one connecting element made of elastic or ductile or breakable material, which is elastically and plastically deformable when movements are imparted to the inertia block, this inertia block being movable in proximity to a fixed opposing surface comprised in the structure itself or in another element of a watch case, and arranged to come into contact with this opposing surface, to impart a proof indicator of impact or a permanent deformation or damage to the inertia block and/or to the connecting element and/or to the opposing surface, and/or to a breakable element incorporated in the shock indicator device), when the acceleration imparted to this inertia block is higher than a given acceleration threshold.

The invention describes a novel method of transducing a force input into a perpendicularly directed advance of a geared component. This simple mechanism allows for the implementation of latches, accelerometers, tilt sensors, and counters that are uniquely inexpensive, robust, compact, and easy to implement, since they are able to rely on purely mechanical operation.

The present invention comprises apparatuses and methods of detecting impacts to the head. Accelerometers attached to a user's head and neck or body is used to measure the differential acceleration of the head with respect to the neck or body. A differential acceleration exceeding a certain threshold may be indicative of the user suffering a traumatic brain injury.

The present disclosure relates to a gas-conducting device having a safety device for interrupting a gas flow in the device. In a resting state, an inertia body is located on a resting place of a housing bottom so that a plunger rests on it. In an activation state, the inertia body moves out of the resting place, the plunger moves toward the housing bottom, and the safety device interrupts the gas flow. The present disclosure provides in that the housing bottom includes at least one guiding structure and that in the activation state the guiding structure guides the inertia body to a deflection point, in that the guiding structure is designed essentially in the shape of a section of a jacket of a cylinder, and in that a longitudinal axis of the cylinder is offset in relation to a vertical axis which is perpendicular to a center point and/or a lowest point of the resting place.

A lone worker system for performing a safety check is provided. The lone worker system includes a mobile device. The mobile device includes a sensor and a memory storing a safety check application thereon and a processor. The processor is coupled to the memory and executes the safety check application under a motion mode including an active tracking of a fall motion event by the sensor. In response to the fall motion event being detected during the active tracking, the processor operates a count utilizing a timer of the safety check application. If the count exceeds a predetermined amount of time, the safety check application enters an emergency mode to execute an emergency alert.

An environmental data recorder includes an enclosure, a first acceleration recorder array positioned on a first inner surface of the enclosure corresponding to an x-z plane defined by an x-axis and a z-axis, a second acceleration recorder array positioned on a second inner surface of the enclosure corresponding to an x-y plane defined by the x-axis and a y-axis, and a third acceleration recorder array positioned on a third inner surface of the enclosure corresponding to a y-z plane defined by the y-axis and the z-axis. The x-axis, the y-axis, and the z-axis are orthogonal axes. The first, second, and third acceleration recorder arrays each include a plurality of beams cantilevered at first ends from a base attached to an inner surface of the enclosure and a plurality of known masses associated with the beams. The beams are configured to deform or break when exposed to different g loads.
