Abstract: Tasks of directed acyclic graphs (DAGs) may be dynamically scheduled based on a plurality of constraints and conditions, task prioritization policies, task execution estimates, and configurations of a heterogenous system. A machine learning component may be initialized to dynamically schedule the tasks of the DAGs.

Abstract: A cured electrode comprising a mixture comprising conductive elements and a carrier which, upon injection into a body, cures from a liquid phase at a first time to a biocompatible solid phase at a second time at or on a target tissue within the body. The cured electrode is capable of being molded around contours of the target tissue so that, after curing, the cured electrode retains the contours of the target tissue. The cured electrode is capable of conducting electricity at a resistance of less than 10 ohm meters in the liquid or the solid phases. Carrier materials include hydgrogel, silicone, bone cement, cyanoacrylate, dental resin and a fibrin mix. The carrier material may also be used to anchor the cured electrode and provide great stability.

Abstract: A hairbrush is disclosed having an elongated, generally hollowed handle having a receiving cavity and a separate brush head having a connection end. At the inside base of the receiving cavity is a first blade slot for retaining one end of a flat, elongated spring blade. The connection end of the brush head has a second blade slot for retaining the other end of the flat, elongated spring blade. A locking button retained slidably within a button slot which penetrates the handle engages into a slotted collar in which a locking slot is formed on the connection end of the brush head by a pair of rotation locking tabs. The impingement of the rotation locking tabs against the locking button thereby prevents rotational motion of the brush head relative to the handle.

Abstract: A hairbrush device includes a limited-excursion, rotating brush head with continuously variable rotational resistance, thereby minimizing tugging-related damage while brushing hair using a simple stroking motion. Thick or tangled hair engages the bristles causing the brush head to rotate from a resting position. A spring means provides increasing resistance in concert with increased rotation of the brush head. When the bristles are removed from the hair, the spring means returns the brush head to its resting position for the next stroke. Preferably, the spring means includes a brush connector releasingly affixed to interchangeable brush heads and releasingly and rotatingly affixed to interchangeable handles. An effective length limiter grips a flat torsion bar affixed to the connector and a shank extends from the gasket axially through the brush handle.
