Abstract: Techniques for interaction based social distance quantification are discloses herein. In one example, a method includes generating an interaction graph having (i) multiple vertices individually corresponding to multiple users and (ii) multiple directional edges individually connecting pairs of the multiple vertices. The method can also include applying graph embedding to convert the multiple vertices in the generated graph into corresponding tensors in a vector space. The method can further includes determining and outputting a social distance value between the one of the multiple users and another of the multiple users by calculating a tensor distance in the vector space between tensors corresponding to the one of the multiple users and the another of the multiple users.

Abstract: Disclosed are wearable indicator devices and methods of using same. The device is a head-mounted device for detecting an alert condition and providing an alert to a user. The device has a display unit with one or more LEDs and a driver circuit configured to control the brightness of the one or more LEDs. The device also has a control unit having a microprocessor, a memory buffer in electronic communication with the microprocessor, a microphone in electronic communication with the microprocessor, and a radio transceiver configured to interface with an external computing system. The microprocessor can be configured to gather audio samples from the microphone, analyze one or more gathered audio samples for an alert condition, transmit the alert condition, and control the LEDs based on the alert condition.

Abstract: A ring-based exercise system collects health metrics and senses rotational movements of a ring moving in a rotational path to calculate exercise results, such as calories burned, and provide instantaneous visual and data feedback. The system monitors the number of calories burned, duration of exercise, and number of rotations, while simultaneously emitting both illumination and audio feedback that correlates to the ring exercise. A ring is twirled around a central axis, such as a torso or limbs. A motion sensor senses the positional information of the ring during the exercise, such as velocity, acceleration, number of rotations, and x-y-z axis motion. A processor, wither integrated into the ring or remotely located calculates the exercise results, i.e., calories burned, through the health metrics and sensor signals. An illumination and an audio signal visible on the ring correlates with the velocity and movement of the ring.

Abstract: An apparatus that facilitates the stretching and exercising of the hamstring and back muscles is provided. The apparatus can be used for stretching to improve flexibility, to warm up muscles before physical activity, and/or for physical rehabilitation after injury. The apparatus includes a set of hand grips and a set of foot plates. A user grasps the hand grips and positions the arches of his or her feet above the foot plates. The apparatus includes a user actuated drive mechanism for moving a set of hand grips along the shaft toward the foot plates. The user maintains a grip of the hand grips as the hand grips move along the shaft toward the foot plates, thereby stretching the hamstring and back muscles of the user.

Abstract: Variable color configuration (VCC) relates to an automated system which allows for the printing of high-quality, highly-personalized documents in relatively small quantities and in a cost efficient manner, when compared with conventional runs. The system relates to a reliable means by which the correct colored images, as well as variable or selective or static or fixed text can be merged into a single, complete document. The system allows for the insertion of fixed as well as variable data into the layout of the document.
