Abstract:
A method is provided that integrated a unique set of structural features for concealing self-powered sensor and communication devices in aesthetically neutral, or camouflaged, packages that include energy harvesting systems that provide autonomous electrical power to sensors, data processing and wireless communication components in the portable, self-contained packages. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers uniquely implement optical light scattering techniques to make the layers appear opaque when observed from a light incident side, while allowing at least 50% and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.

Abstract:
According to some aspects, a power regulation system for energy harvesters that lacks a battery is provided. In some embodiments, the power regulation system may receive power from multiple energy harvesters that generate energy from different sources, such as wind currents and ambient light. In these embodiments, the power regulation system may selectively provide power from one or more of the energy harvesters to a load as environmental conditions change and power itself with energy from the energy harvesters. Thereby, the power regulation system may start and operate without a battery and provide power to the load over a wider range of environmental conditions.

Abstract:
Provided is a portable controller and associated method that provides a patient or caregiver the ability to recharge and alter the parameters of an implanted medical device, while allowing the patient substantially unobstructed mobility. To enable mobility, the controller may be worn on a belt or clothing. The controller also allows the patient to turn device stimulation on and off, check battery status, and to vary stimulation parameters within ranges that may be predefined and programmed by a clinician. The controller communicates with the medical device to retrieve information and make parameter adjustments using wireless telemetry, and it can send and receive information from several feet away from the implanted medical device. Charging of a battery contained in the implanted medical device is achieved via an inductive radio frequency link using a charge coil placed in close proximity to the medical device.
