    Abstract: A method of creating a miniature multicellular biological construct and a method for studying cellular environments using the miniature multicellular biological construct is provided. The method for making the miniature multicellular biological construct includes suspending cells in a hydrogel, depositing the cell-suspension into a microwell, gelling the cell-suspension, and incubating the cell-suspension. The method for studying cellular environments includes imaging the miniature multicellular biological construct.

    Abstract: Multiple designs, systems, methods and processes for controlling a system or plant using an extended active disturbance rejection control (ADRC) based controller are presented. The extended ADRC controller accepts sensor information from the plant. The sensor information is used in conjunction with an extended state observer in combination with a predictor that estimates and predicts the current state of the plant and a co-joined estimate of the system disturbances and system dynamics. The extended state observer estimates and predictions are used in conjunction with a control law that generates an input to the system based in part on the extended state observer estimates and predictions as well as a desired trajectory for the plant to follow.

    Abstract: A rotation monitoring system may be attached to a limb and can identify ranges of motion that are associated with injuries or poor performance. In some embodiments, the device is designed to monitor flexion and orientation of joints and limbs, developed specifically around identifying stress concentrating behavior on the ACL. Tests performed show that the designed device can read flexion and orientation of the knee, is durable enough to be used in real-world conditions, and does not impede on the subject's movements.
