Abstract: A tracking tag of a tracking system configured to receive, by one or more processors of the tracking tag, a first measurement collected by one or more sensors of the tracking tag; determine, by the one or more processors, a degree of similarity between the first measurement and a critical value; compare, by the one or more processors, the degree of similarity between the first measurement and the critical value to a first threshold value; modify, by the one or more processors, an initial time interval based on the comparison of the degree of similarity between the first measurement and the critical value to the first threshold to determine a modified time interval; and transmit, by the one or more processors, one or more beacon signals according to the modified time interval.

Abstract: The technology relates to a wireless system that can be used indoors or outdoors, and is configured to reduce interference of beacon signals on channels used by the system. Aspects of the technology provide for evaluation of channel activity to determine an optimal transmission channel. This is beneficial where there is a high density of tags that may be configured for data transmission. Tags may include an antenna to receive signals; a first conditioning element to attenuate received signals corresponding with the system channels; a converter and a second conditioning element to prepare attenuated signals for analysis; a comparator to compare an attenuated signal to a threshold value; and a processor to transmit a beacon signal to a reader apparatus based on the comparison.

Abstract: An energy harvesting tape comprising a plurality of flexible layers. The plurality of flexible layers includes a solar cell layer configured to capture solar energy, a thermoelectric layer configured to capture thermal energy, one or more piezoelectric layers configured to capture mechanical energy; and an electrode layer configured to capture radiofrequency energy and to transmit a radiofrequency signal. The energy harvesting tape also includes one or more processing units on at least one of the plurality of flexible layers. The one or more processing units are configured to use the captured energy from the plurality of flexible layers to transmit the radiofrequency signal. The energy harvesting tape has a length, a width, and a thickness, where the length is greater than the width, and the width is greater than the thickness.

Abstract: Aspects of the disclosure provide a method of coordinating beacon signal scanning of reader devices in a tracking system. For instance, first information may be received from a first reader device of the tracking system, and second information may be received from a second reader device of the tracking system. Based on the first information or the second information that one of the first reader device or the second reader device has moved may be determined. In response to the determination that the first reader device or the second reader device has moved, a first coordinated duty cycle for the first reader device and a second coordinated duty cycle for the second reader device may be determined. The first coordinated duty cycle may be provided to the first reader device, and the second coordinated duty cycle may be provided to the second reader device.

Abstract: Aspects of the disclosure provide for testing of tracking tags. Tracking tags may include circuitry configured to operate in a normal operating mode for sending first beacon signals to enable the tracking of objects, and to operate in a testing mode for sending second beacon signals to enable testing of the tracking tag. A testing system may include a reader including an antenna configured to receive one or more beacon signals. The example system may also include one or more computing devices having one or more processors and being in communication with the reader. The one or more computing devices may also be configured to induce a tracking tag to generate the one or more beacon signals in a testing mode, the one or more beacon signals including an encrypted or unencrypted payload. The system may use the payload to determine whether to mark the tracking tag to be discarded.

Abstract: The technology relates to a wireless system that can be used indoors or outdoors, and is configured to reduce interference of beacon signals on channels used by the system. Aspects of the technology provide for evaluation of channel activity to determine an optimal transmission channel. This is beneficial where there is a high density of tags that may be configured for data transmission. Tags may include an antenna to receive signals; a set of first conditioning elements to attenuate received signals corresponding with system channels; a set of converters and a set of second conditioning elements to prepare attenuated signals for analysis; a comparator to determine which attenuated signal corresponds to a channel having the lowest power level; and a processor to transmit a beacon signal to a reader apparatus on the channel with the lowest power level.
