Abstract: Small, low-cost satellite systems, like CubeSats or other microsatellites, can exhibit reduced reliability relative to higher-cost satellite systems. This can result in difficulty identifying, communicating with, and tracking such satellite systems when they fail. Provided herein are reliable, low-cost, low-energy, turn-key systems for identification and tracking of small satellites that can be readily added to a microsatellite with minimal integration costs and while occupying a minimal amount of volume, mass, and external area of the host satellite. These systems are electrically isolated from the satellite bus, being powered by internal batteries or other separate energy sources and providing reliable identification and tracking even when the other systems of the satellite have failed.

Abstract: We use permanent magnets to levitate and transport heavy loads. A bed of permanent magnets is selectively actuated to levitate an array of magnets positioned above the bed, such that the magnets in the levitated array are opposed to the actuated magnets, and of the same magnetic pole, thereby creating a repulsive force. The actuated magnets are offset from magnets in the bed of permanent magnets that have not been actuated, thereby imparting maximum levitation forces to the magnets in the levitated array. Our systems use magnetic repulsive force for levitating and transporting goods across a warehouse, simulating walking or running such as on a treadmill or in a virtual gaming platform, and for transporting people such as on a moving sidewalk. Our systems are electrical machines for holding or levitating devices using magnetic levitation, and also use permanent magnets to transmit power wirelessly.

Abstract: Systems and methods of generating and applying a synthetic neuromodulatory signal are described. A subject may be put under a particular condition that causes an effect in the subject. While the subject is under the condition, a recording of neurogram signals derived from the condition can be made from the subject. For example, neuronal signals traveling on the vagus nerve of the subject may be monitored and recorded. The neurogram may then be used to create a synthetic neuromodulatory signal that can be administered to a user. When the synthetic neuromodulatory signal is administered to the user, the user may experience the same effect as the subject that had been placed in the condition, even though the user was never put under the same condition.

Abstract: A variety of brake and/or clutch mechanisms, and improvements thereof, are provided having improved braking power, reduced size and weight, and other benefits. The braking mechanisms include a wrap spring clutch that is operable to mechanically couple a rotating member to a brake rotor that is in consistent contact with a brake pad. Actuation of the wrap spring clutch allows the wrap spring to engage with the rotating member, coupling the rotating member to the brake rotor thus braking the rotating member. The combination of the wrap spring clutch with the brake rotor and pad provides an overall braking mechanism that exhibits the decreased power cost, weight, size, and engagement time of the wrap spring clutch while having a braking power that can be moderated by specifying the area, engagement force, coefficient of friction, or other properties of the brake rotor and pad.

Abstract: A variety of shifter mechanisms are provided for controlling the axial distance between half-pulleys of a split pulley variable transmission, thus controlling the transmission ratio of the variable transmission. Some of these embodiments include a differential such that a variable transmission can be driven and shifted differentially by two inputs. A torque or rotation difference between the inputs results in a change in the transmission ratio and in-common torque or rotation is transmitted through the transmission to an output. The same motors used to drive the output of the transmission are thus also able to effect shifts in the transmission ratio. Accordingly, motor mass that is not being used to effect high-speed shifts may be used to drive the transmission output, and vice versa. The provided shifter embodiments are well-suited to application to nested-pulley variable transmissions, including nested-pulley infinitely variable transmissions.
