Abstract: A system comprising a particle confinement assembly and one or more signal manipulation elements is provided. The particle confinement assembly defines a plurality of particle positions. Each signal manipulation element of the one or more signal manipulation elements (a) is associated with at least one respective position of the plurality of particle positions and (b) comprises an active nanophotonic component having a dynamically controllable optical effect. A respective signal manipulation element of the one or more signal manipulation elements is configured to, responsive to an incident signal being incident thereon and based on a state of the dynamically controllable optical effect, cause either (a) an induced signal to be incident on at least a portion of the at least one respective position or (b) an induced signal to be incident on a respective collection location corresponding to the at least one respective position.

Abstract: A wearable ultrasound device and method of using the device includes a power controller with a power source and at least one integrated circuit that delivers electrical power to an applicator. The applicator is electrically coupled to the power controller and a surface of the applicator transmits ultrasound to a wearer for a given duration. The applicator includes radio frequency (RF) drive electronics, an ultrasound transducer coupled to the drive electronics, a monitoring apparatus that includes a thermal cutoff coupled to the drive electronics, where the monitoring apparatus monitors a temperature of the applicator surface and the thermal cutoff turns off the applicator, if the temperature exceeds a pre-defined threshold, and a coupling bandage coupled to the applicator, where the bandage positions the surface of the applicator proximate to a wearer at a location on the body of a wearer.
