Abstract:
Disclosed are devices, systems and methods for a monitoring system for autonomous vehicle operation. In some embodiments, a vehicle may perform self-tests, generate a report based on the results, and transmit it to a remote monitor center over one or both of a high-speed channel for regular data transfers or a reliable channel for emergency situations. In other embodiments, the remote monitor center may determine that immediate intervention is required, and may transmit a control command with high priority, which when received by the vehicle, is implemented and overrides any local commands being processed. In yet other embodiments, the control command with high priority is selected from a small group of predetermined control commands the remote monitor center may issue.

Abstract:
Secure and efficient methods and systems of providing multiple access interference constraints for frequency hopped spread spectrum communications are presented. The methods and systems leverage a cryptographic keystream generator and iterative indexing into shuffled lists to generate a constrained collision-free frequency hopping sequence. This flexible frequency hopping access (FFHA) can support varying hop frequency and bandwidth resources including secure operation for applications where the number of channels (hopping sequences) exceeds the number of hop frequency resources available.

Methods, systems, and devices are disclosed for administering a medicament to a patient. In one aspect, a system includes an injection pen device in wireless communication with a mobile communication device. The injection pen device includes a housing including a chamber to encase a cartridge containing medicine, a dose setting and dispensing mechanism to set the mechanism to dispense a particular dose of the medicine from the loaded cartridge, a sensor unit to detect a dispensed dose based on positions and/or movements of the dose setting and dispensing mechanism, and an electronics unit in communication with the sensor unit to process the detected dispensed dose and time data associated with a dispensing event and to wirelessly transmit the dose data to a user's device. The mobile communication device provides a software application to provide the user with health information using the processed dose data.
