Abstract: Systems and methods for operation and wireless monitoring of personal safety devices are disclosed. A personal safety device comprises processing circuitry, a radio transmitter, a multi-part button, at least one motion-or-position sensing device, a haptic motor, and an indicator light each coupled to the processing circuitry. The processing circuitry periodically broadcasts signals in a wireless beacon format via the radio transmitter including a unique identifier associated with the personal safety and additional information indicating a current state of the personal safety device. A server receives the signals, determines the location of the personal safety device, and provides notifications of the status of the personal safety device to users via a user interface.

Abstract: A method, system, and non-transitory computer-readable medium are disclosed. The method includes determining, by a server, an inventory of tags in communication with a gateway using a first wireless communication mode, and enabling, in response to a first triggering event recognized by a tag, a second wireless communication mode. The method also includes enabling, in response to a second triggering event recognized by the tag, a third wireless communication mode and a location detection capability of the tag. The method further includes determining, by the tag, a geographic location of the tag using a location detection capability, and transmitting, using the third wireless communication mode, to a server the geographic location of the tag.

Abstract: An example system includes a first beacon configured to communicate a first wireless signal. A first hub is in communication with the first beacon. The first hub is configured to detect a first signal strength of the first wireless signal. The example system further includes a second hub in communication with the first beacon. The second hub is configured to detect a second signal strength of the first wireless signal. The example system further includes a computing system in communication with the first hub and the second hub. The computing system includes a noise filter and a beacon assignor. The noise filter includes a quadratic estimator configured to output a first estimated distance between the first beacon and the first hub, output a second estimated distance between the first beacon and the second hub, and disregard a third estimated distance between the first beacon and the first hub if the third estimated distance is derived from a ghost signal.

Abstract: A method includes determining, by a tag, that a gateway is not within communication range of the tag using a first wireless communication mode and enabling, in response to the tag determining that the gateway is not within communication range of the tag, a second wireless communication mode. The method also includes determining, by the tag, that a mobile device is not within communication range of the tag using the second wireless communication mode and enabling, in response to the tag determining that the mobile device is not within communication range of the tag, a third wireless communication mode and a location detection capability. The method further includes determining, by the tag, a geographic location of the tag using the location detection capability and transmitting, using the third wireless communication mode, to a server the geographic location of the tag.
