The present invention generally relates to an attachment for a firearm that communicates with remote device or person such as emergency services. One embodiment of the present invention is selectively interconnected to a picatinny rail, weaver rail, or other mounting means, and the embodiment includes a button that allows a user to initiate communication with emergency services without removing his or her hands from the firearm.

Various embodiments provide systems and methods for identifying impairment using measurement devices.

Systems and methods are provided for worker protection system with ultra-wideband (UWB) based anchors. One or more wayside units placed on or near a track may be configured to form a work zone network, based on ultra-wideband (UWB) communications, corresponding to a work zone in an area surrounding or in proximity to the one or more wayside units. When the work zone network is formed, at least one wayside unit of the one or more wayside units may be configured to obtain ranging information to a train traversing the track, based on communications of UWB signals with at least one train-mounted unit deployed on the train, and the one or more wayside units are configured to generate, based on the ranging information, notifications relating to the train and/or the work zone.

Systems and methods of tracking attributes of objects, including a sensor configured to detect data related to one or more attributes of the object, a tracking device attachable to the object to transmit data detected by the sensor, a software application modifiable by a user, the software application being configured to receive transmitted data from the tracking device, firmware within a chip on the tracking device configured to determine a frequency of data transmissions from the tracking device to the software application based on transmission rules related to characteristics of transmitted data, and a display configured to show the frequency of data transmissions from the tracking device to the software application.

An apparatus, including a controller, camera, display, speaker, global positioning system, and sensor or detector which senses or detects a dangerous, hazardous, or unsafe, condition at or in a vicinity of the apparatus. The sensor or detector senses or detects the dangerous, hazardous, or unsafe, condition, and the apparatus provides, via the speaker, an audible alarm, siren blare, or verbal message, containing information regarding the dangerous, hazardous, or unsafe, condition. The apparatus or the controller generates an alert message containing information regarding the dangerous, hazardous, or unsafe, condition. The apparatus transmits the alert message to a central processing computer, to a communication device of a parent, relative, or friend, or other authorized individual, or to a police or law enforcement communication device.

Systems and methods for providing timely location estimates when a user equipment initiates a call to an emergency number are disclosed. The system enables a user equipment and network nodes (e.g., eSMLC/LMF) to send multiple location responses instead of just one so that the PSAP can benefit from accurate location techniques in a timely manner. For example, when a user equipment is located in an outdoor environment, it can immediately send its A-GNSS location after meeting quality-of-service (QoS) criteria, and the eSMLC/LMF can forward the location estimate to the PSAP immediately without first waiting for all of the other location estimates. When location estimates become available from other technologies (e.g., E-CID, or DBH, or both), the eSMLC/LMF can send to the PSAP another location response for that technology. As a result, the PSAP can always have the most accurate and up-to-date location information available to timely and accurately respond to emergency calls.

A system and method for providing a temperature-based message warning system for occupants of vehicles is disclosed. The dashcam-message generator includes a dashcam coupled to the dashcam-message generator, a thermometer coupled to the dashcam-message generator, a GPS receiver, a memory having instructions stored thereon; and a processor configured to execute the instructions on the memory. The dashcam-message generator measures an internal temperature of a vehicle using the thermometer, when the internal temperature is greater than a threshold value, the dashcam-message generator obtains images from the dashcam, detects an occupant within the vehicle using the images, generates a warning message regarding the occupant within the vehicle with a temperature above the threshold value, and transmits the warning message to one or more emergency contacts.
