Abstract: Technologies for determining driver efficiency include receiving, by a telematics server, accelerometer data from a telematics device located in a vehicle driven by a driver. The accelerometer data defines a pattern of acceleration of the vehicle over a time period. The telematics server determines a driver efficiency score of the driver based on the accelerometer data. The driver efficiency score is indicative of an average absolute acceleration of the vehicle over the time period. The determined driver efficiency score may be compared to a reference efficiency score and/or efficiency scores of other drivers to rank the drivers.

Abstract: Techniques are disclosed for facilitating disabling an alarm in response to particular types of activity-indicative data. More specifically, activity-indicative data (e.g., sensor data or input(s) can be detected prior to a preset alarm time. Upon determining, based on the activity-indicative data, that a wakefulness condition is satisfied (e.g., that the activity-indicative data corresponds to one or more predefined characteristics), a disablement query can be displayed that includes an option to disable the alarm. In response to detecting a selection of the option, the alarm can be disabled such that the alarm stimuli is not to be presented at the preset alarm time.

Abstract: Disclosed examples include those directed to detecting and remediating detachment of electrodes from a patient. In an example, a system calculates a Pearson correlation coefficient between: (1) power spectral density of the noise and (2) power spectral density of a recorded signal (e.g., from an electrode being operated in free-run EMG mode). If the recorded signal correlates with the noise, then the system notifies the user of presence of noise (e.g., the fallen electrode). Otherwise, the recorded signal is considered as the signal of interest (e.g., a valid EMG signal).

Abstract: Systems and methods are disclosed herein for a mobility management system that serves as a data processing intermediary between mobility operators and governing entities that define rules associated with vehicle behavior occurring in a geographic region. The system receives from a mobility operator historical vehicle data including GPS locations for fleet vehicles within the geographic region. The system determines aggregate behavior metrics for the vehicles using the behavior data. If the aggregate behavior metrics exceed one or more behavior thresholds for a specified time period, the system generates one or more suggested behavior modifications for the vehicles or mobility operators. Moreover, the historical vehicle data may be used to train a machine-learned model to predict a number and behavior of vehicles within the geographic region at a specific time, and if the current number or behavior of vehicles satisfies pre-determined governing criteria, the system modifies one or more vehicle rules.
