XCB tracking devices, methods and systems

XCB poly-radio devices as finders, locators, scanners, sensors, and Bluetooth (BT) radio topology reporters as part of a global lost-and-found services system. XCB devices function as “smart objects” and combine dual transceivers operating in the telecommunications and the low power ISM radio spectra, with default power management overrides under local control of the BT modem. “Familiar zones” are defined, and a “familiarity index” versus a “strangeness index” based on meta-analysis of BT radio contact logs are used to assign location. Location, in concert with other sensor data, is coupled to conditional logic rules programmable by the user or the system administrator. Locations, determined by monitoring familiar and unfamiliar BT radio topology, trigger executable commands to smartphones, to smart devices generally, and to remote machines, and can for example, generate alerts to a user if radiotagged assets, children or pets have strayed, are lost, or are left behind. When tied to cloud predictive services or increased edge computing capacity, incipient loss of radiotag objects can be detected before an owner knows the smart object is lost. In another embodiment, XCB devices having a novel chip architecture for improved power management of cellular and MCU circuits mediated by BT radio modem that achieves “situational awareness” by monitoring the BT signal environment around the device.

Testing a semiconductor can be time-consuming as the chip architecture becomes more complex. Testing the possible scenarios becomes increasingly difficult. Chip quality characteristics relating to the chips on a wafer can be used to estimate a probability or rating relating to bypassing system-level testing (SLT). A chip can bypass SLT if there is a high likelihood of passing SLT. Thousands of chip characteristics can be received from wafer testing, chip probe testing, environmental parameters, factory parameters, and other parameters. A chip quality model can use chip quality characteristics as input to generate chip group and SLT parameters. The chip quality model can be a machine learning model or other types of machine learning systems.
