Abstract:
A penalty allocation system includes a processing circuit configured to receive first data from a first player-worn sensor regarding a first player involved in an impact, receive second data from a second player-worn sensor regarding a second player involved in the impact, identify one of the first player and the second player as an at-fault player in connection with the impact based on the first data and the second data, and determine a penalty for the at-fault player based on the first data and the second data.

Abstract:
A three-dimensional map of an environment with buildings is used to computationally predict locations and times of global navigation satellite system (GNSS) transmission quality. A global navigation satellite system (GNSS) receiver can reconcile received satellite transmissions with these predicted satellite transmissions. By comparing actual transmission quality with predicted transmission quality, a system can determine unmodeled obstructions, temporary obstructions, jamming, spoofing or other origins of interference with predicted transmission quality of a satellite in a GNSS.
Abstract:
A three-dimensional map of an environment with buildings is used to computationally predict locations and times of global navigation satellite system (GNSS) blockages. For example, in urban environments some of the GNSS satellites are occluded by buildings. These blockages can be modeled. A computing system can make a map showing which satellites are or are not visible as a function both of location and time. The map can be used by a mobile GNSS receiver to determine which satellites to use or whether to use a backup system for navigation. The system can determine when a given satellite will enter or leave a GNSS receiver view during a route. The map can be stored in the GNSS receiver (or a host of the GNSS) or can be stored by a network service. This mapping can be used to predict multi-path effects of a satellite transmission at a location.
Abstract:
Systems and related methods for delivering a stimulus to a pinna of a subject with a stimulator worn on the pinna are described. A wearable stimulation device includes a mechanical, electrical, or other type of stimulator secured to a pinna of a subject. The stimulation device may be used to deliver a stimulus that modulates activity of sensory nerve fiber innervating the pinna. Stimulation may be delivered in response to a sensed neural signal indicative of a physiological status of the subject, and/or in response to sensed environmental parameters. Stimulation may be delivered in combination with other stimuli or experiences. In an aspect, a stimulator communicates with and/or is controlled by a personal computing device.
Abstract:
An embodiment of a device includes a sensor and a communicator. The sensor is configured to be attached to a body portion of a subject, to sense an object, and to generate information related to the object. The communicator is configured to provide the information to a determiner-notifier that is configured to determine, in response to the information, if the body portion may contact the object, and to generate a notification in response to determining that the body portion may contact the object. Such a device (e.g., attached to, or part of, a shoe) may be useful to warn a subject of a potential collision between an object (e.g., stairs, furniture, door jamb, curb, toy) and a body part (e.g., foot, toes) in which the subject has lost feeling, the ability to feel pain, or proprioception. And such a warning may help the subject to avoid inadvertently and repeatedly injuring the body part.
Abstract:
The present disclosure provides systems and methods for storing, reading, and writing data using particle-based acoustic wave driven shift registers. The shift registers may physically shift particles along rows and/or columns of wells through the interactions of two parallel surfaces. A transducer may generate an acoustic wave to displace one or more of the two parallel surfaces. The particles may be transferred to and/or otherwise constrained by a buffer surface during at least a portion of the acoustic wave, such that the particles may be shifted during one or more cycles of the acoustic wave. In various embodiments, the amplitude of the acoustic wave may correspond to the spacing distance between each of the wells. The wells may be physical and/or potential wells.
Abstract:
A safety rail monitoring system, and associated methods of operation, for monitoring use of a safety rail that borders a footpath to help prevent injuries while the user traverses the footpath. The safety system includes a sensor system for detecting the presence of a user on the footpath and the presence of a contact by the user on the safety rail. A sensor observation system in communication with the sensor system receives signals indicating whether the user is present on the footpath and whether the user is holding on to the safety rail. If the user is not holding on to the safety rail, the sensor observation system generates an alert signal to the user to remind the user to hold the safety rail. In some embodiments, the safety system may include a barrier that prevents the user from continuing along the footpath without contacting the safety rail.
