    Abstract: A method of detecting impairment of a driver of a vehicle. The method includes sensing, using a sensor, a position of the driver's head at a plurality of time points; determining, using a microprocessor, changes in the position of the driver's head between the plurality of time points; evaluating, using a microprocessor, whether the changes in the position of the driver's head between the plurality of time points exhibit at least one of a periodic and a quasi-periodic pattern; determining whether the driver is impaired based on the pattern of the changes in the position of the driver's head; and if the driver is impaired, alerting the driver using an alarm.

    Abstract: A system for monitoring operator alertness. The system includes a sensor for detecting a head position property of a head of an operator and a controller in operative communication with the sensor. The controller is configured to collect a first plurality of time points of the head position property of the head of the operator, determine a baseline of the head position property of the head of the operator based on the first plurality of time points, collect a second plurality of time points of the head position property of the head of the operator, determine an operating condition of the head position property of the head of the operator based on the second plurality of time points, and evaluate the alertness of the operator based on a comparison of the operating condition to the baseline to identify a period of head stillness.

    Abstract: A system and method for calibrating one or more sensing features for a furniture item detection is provided. More particularly, embodiments relate to determining a first noise state associated with an environment of the furniture item based on a first measured noise received from one or more sensors associated with the furniture item. A first baseline noise level for the furniture item can be generated based on filtering the first noise state associated with the environment of the furniture item. A second noise state associated with the environment of the furniture item can be determined based on a second measured noise received from the one or more sensors associated with the furniture item. A second baseline noise level for the furniture item can be generated based on filtering the second noise state associated with the environment of the furniture item. The first baseline noise level can then be adjusted to the second baseline noise level.

    Abstract: An inductive-charging device mounts into a through hole of a furniture item, such as a desk. The device generally includes a housing that mounts into the through hole and that provides a compartment for a controller, primary coil, and other electronic components used to provide inductive charging. The device might be mounted so that it at least partially extends above a work surface of a desk. Alternatively, a top of the device might be flush with the work surface.

    Abstract: Aspects herein are directed to systems and methods for synchronization of actuators to reposition furniture units. Specifically, a master control box receives input to reposition a furniture unit from one position to another and communicates the input to a plurality of control boxes. Then, each of the plurality of control boxes assigns a virtual axis to each of a plurality of actuators attached to each associated control box. Furthermore, each of the plurality of control boxes assigns a transfer function to each of the plurality of actuators. The transfer function is used by the actuators to transform an output of the virtual axis to determine a target position. In this way, the plurality of actuators can reference the same virtual axis for synchronization purposes, but use different transfer functions to maintain complex relationships between the positions of each actuator. Based on the target position, the actuators reposition the furniture unit.
