Abstract: Disclosed herein are systems, methods, and devices for facilitating officials during a sporting event. According to one embodiment, a device is disclosed including a processor, a memory electrically coupled with the processor, a microphone interface electrically coupled with the processor, a user interface electrically coupled with the processor, a haptic feedback device electrically coupled with the processor; and a wireless transceiver electrically coupled with the processor.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: A mobile radio direction finding (RDF) calibrator, and a method of using it to calibrate an RDF system aboard a vehicle. The calibrator has a GPS (global positioning satellite) or other GNSS (global navigation satellite system) receiver, which permits the calibrator to make its location known to the calibration process of the RDF-equipped vehicle. During calibration, the calibration process controls the calibrator remotely. As the RDF-equipped vehicle moves in a circle, it collects calibration response data, as well as location data, so that the calibration response data can be mapped to the correct azimuth.
