Abstract: A tunable voltage regulator has an output generating a variable voltage and an input that receives a trimming signal for controlling the output variable voltage. A current regulating circuit operates to regulate a current flowing through a load in response to the variable voltage. A control circuit senses the variable voltage and a drop voltage of the current regulating circuit, and determines whether the current regulating circuit has failed to regulate the current flowing through the load because the variable voltage is too low. In response thereto, the control circuit generates the trimming signal to set the variable voltage to a value sufficient for the current regulating circuit to successfully regulate the current flowing through the load.

Abstract: One embodiment of a power management system includes a reservoir configured to collect energy. The system also includes a voltage regulator coupled to the reservoir via an input terminal and configured to convert the energy to an output voltage via an output terminal when enabled. A threshold detector is coupled to the reservoir and is configured to sense the energy and enable the voltage regulator when the energy exceeds a threshold. The system further includes a feedback circuit coupled between the output terminal and the threshold detector, and configured to feedback the output voltage to the threshold detector to compensate for a voltage drop across the threshold detector due to an output current drawn by the load.

Abstract: This application discloses systems, devices, and methods for indoor navigation and tracking with a mesh network. In one aspect, a navigation device includes a receiver configured to receive a locational signal from a node network. The locational signal identifies a respective node of the node network, and the node network is distributed throughout a physical space. The navigation device includes a memory storing a program and a processor in communication with the receiver and configured to execute the program to calculate a position of the navigation device from the identity of the respective node, determine a routing instruction from the position of the navigation device to a destination based on the position of the navigation device and a known mapping of the node network in the physical space, and update the position of the navigation device and the routing instruction as the navigation device moves through the physical space.
