Abstract: An API server receives an audio message generated at a client device of a user. The audio message is to be played to a wearer of a wearable device. The API server identifies one or more constraints associated with the audio message. The one or more constraints define when the wearable device is to play the audio message. The API server saves the audio message and the one or more constraints in a cloud storage environment. A gateway server detects that the cloud storage environment includes the audio message. Based on the detecting, the gateway server prompts the wearable device that the audio message is available for download. The gateway server receives a request from the wearable device for the audio message. Responsive to receiving the request, the gateway server causes the audio message to be played to the wearable device.

Abstract: A parking availability predictor system provides a prediction of parking availability that meets a user's specified needs. When the user submits a query for parking availability, he can include desired parking criteria such as location, handicapped status, and desired time to begin parking. The system consults a parking occupancy model which gathers current and historical information about parking occupancy, including parking durations and durations of vacancies between occupancies. The model processes the gathered information into a statistical predictor of parking occupancy and vacancy. The system uses the predictor to predict when parking that meets the user's needs will become available. That prediction, including user-suitable parking locations along with the expected start of their vacancies, is then sent to the user in answer to his query.

Abstract: A skateboard deck that is both stiff in one dimension and flexible in another dimension is disclosed. The deck includes an elongated body characterized by a longitudinal axis, a plurality of ribs, and a plurality of apertures. The plurality of ribs are long, narrow beams oriented substantially parallel to the longitudinal axis and integral with the bottom of the elongated body. The plurality of apertures are distributed in a plurality of rows also oriented substantially parallel to the longitudinal axis. The ribs and rows of apertures are interposed in an alternating pattern across the width of the deck. The resulting deck is stiff in the longitudinal direction yet flexible with respect to rotation about the longitudinal axis. The deck is therefore flexible enough to enable the front and rear trucks to rotate with respect to one another while still being rigid enough to withstand the weight of the rider.

Abstract: Disclosed herein is a technique of configuring flexible photovoltaic tracker systems with high damping and low angle stow positions. Under dynamic environmental loads implementing a high amount of damping (e.g., greater than 25% of critical damping, greater than 50% of critical damping) or a very high amount of damping (e.g., 100% or greater of critical damping, infinite damping) enables the flexible tracker system to prevent problematic aeroelastic behaviors while positioned in a low stow angle. The disclosed technique is further applied to a prototyping process during wind tunnel testing.
