Abstract: A banded sports bra for supporting breasts during exercise or other rapid movement of a person is provided. The banded sports bra has several pathways for bands that allow support of the breasts during oblique and downward breast motion. The banded sports bra can have left and right primary bands that form a rotated “S” shape about the breasts to reduce unwanted movement of the breasts. The banded sports bra can also have a secondary band that is provided under the breasts to reduce downward motion of the breasts. The primary and secondary bands can be adjustable to control the tension provided by the bands at tension adjustment regions with adjustment straps.

Abstract: Circuit breakers based on micro-electromechanical systems (MEMS) switches are described. A high voltage MEMS teeter-totter switch can include a beam coupled to an anchor on a substrate and two control electrodes, disposed on a surface of the substrate. A control voltage applied on one of the control electrodes with respect to a first reference voltage puts one of the two ends of the beam in electric contact with one of two contact electrodes of the MEMS teeter-totter switch to electrical connected two terminals of a circuit breaker. The input voltage is applied on the beam with respect to a second reference voltage different from the first reference voltage. A MEMS teeter-totter switch network comprises a plurality of MEMS teeter-totter switches configured to switch high voltage and high current between the two terminals of the circuit breaker.

The input voltage is applied on the beam with respect to a second reference voltage different from the first reference voltage.
