The present application is directed towards methods and systems for an interactive cyclist monitoring and crash prevention system. The methods include creating, by a safety sensor, a virtual smart lane around a bike operated by a rider during a cycling session. The virtual smart lane may indicates a safe zone around the bike. The method further includes the safety sensor detecting an object approaching the virtual smart lane during the cycling session and generating an alert to the rider of the bike to notify the rider of the approaching object.

The Active Knee Rehabilitation Orthotic System (ANdROS) is a wearable and portable assistive tool for gait rehabilitation and monitoring of people with motor control deficits due to a neurological ailment, such as stroke. ANdROS reinforces a desired gait pattern by continually applying a corrective torque around the knee joint, commanded by a impedance controller. A sensorized yet unactuated brace worn on the unimpaired leg is used to synchronize the playback of the desired trajectory based on the user's intent. The device is mechanically grounded through two ankle foot orthoses (AFOs) rigidly attached to the main structure, which helps reduce the weight perceived by the user.

The present disclosure provides a gear set. The gear set includes a ring gear including a plurality of ring gear teeth on an inner radial edge of the ring gear and an arcuate ring roller positioned axially outward of the ring gear teeth. The gear set includes a sun gear having a plurality of sun gear teeth positioned about an outer radial sun gear edge and an arcuate sun gear roller positioned axially outward of the sun gear teeth. The gear set includes a planetary gear positioned in the ring gear between the sun gear and the ring gear. The planetary gear includes a plurality of planetary gear teeth positioned about an outer radial planetary gear edge. The plurality of planetary gear teeth engage the sun gear teeth and the ring gear teeth. The planetary gear includes an arcuate planetary gear roller positioned axially outward of the planetary gear teeth. The arcuate planetary gear roller engages the arcuate ring roller and the arcuate sun gear roller.

A method of constructing an object includes depositing a first material in a predetermined arrangement to form a structure. The method further includes depositing a second material within the structure. The second material may have electrical properties and the method also includes providing electrical access to the second material to enable observation of the one or more electrical properties.

Disclosed are methods and systems for using hieroglyphs for communication in a rapid fabrication environment. The method includes receiving, by a control system for an articulated robotic arm, one or more images of a fabrication machine build space. The method includes identifying, by the control system, a hieroglyph present in the one or more images and translating the identified hieroglyph into one or more instructions for manipulation of the articulated robotic arm. The method includes causing the articulated robotic arm to carry out the instructions translated from the identified hieroglyph. Accordingly foreign objects are inserted into fabricated objects during an automated rapid fabrication process without extensive redesign of the rapid fabrication machine. In some implementations, an unmodified third-party stereolithographic rapid fabrication machine can be used.

The present application is directed towards methods and systems for an add-on smart pedal and computer based application to provide cyclist monitoring and recommendations. The methods include displaying, by a virtual coach, characteristics of a bike in a first virtual cycling session, the characteristics measured by a pedal sensor during a cycling session. The virtual coach may assess a performance of a rider during the cycling session and generate recommendations the first virtual cycling session based on the performance of the rider. Further, the virtual coach may create a second virtual cycling session based on the rider performance and the recommendations.
