  • Patent number: 10671067
    Abstract: Embodiments include devices and methods for maintaining control of a robotic vehicle when control signals from a main controller are lost. A detector circuit may monitor signals from the main controller to an electronic speed controller (ESC) to detect a loss of valid control signals. The detector circuit may cause an auxiliary controller to begin issuing motor control signals to the ESC in response to detecting a loss of valid control signals. The auxiliary controller may be configured to issue motor control signals to the ESC according to a pre-loaded set of motor control instructions. The pre-loaded set of motor control instructions may be received from the main controller and/or may be configured to cause the auxiliary controller to issue motor control signals to the ESC that control motors in a manner that causes the robotic vehicle to enter a safe mode of operation or execute a particular maneuver.

  • Patent number: 10576289
    Abstract: Techniques described herein address these and other issues by providing an architecture of antennas capable of generating a relatively even H-field without exceeding exposure limits, while solving communication issues at the same time. More specifically techniques described herein are directed toward the use of multiple antennas that enable an interrogator device of a biological measurement and stimulation system to power different groups of medical implants at different times by creating fields in different regions of the brain. By doing this, the interrogator device can independently power and/or communicate with groups of medical implants in these different regions and create more evenly-distributed fields while doing so.

  • Patent number: 10523023
    Abstract: Techniques for charger-device pairing for recharge warnings are described. In one or more implementations, a battery of a device is determined to require charging based on a state of charge of the battery. In response to this determination, a message is communicated via a local network from the device to a charger that was previously paired with the device. The message includes a request for the charger to generate a first alert indicating that the charger is available to charge the battery of the device. In addition, the device provides a second alert indicating that the battery of the device requires charging.
