Abstract: A dual-function supercapacitor carbon fiber composite stores electrical energy and functions, for example, as the body shell of electric vehicles (EVs). This is achieved with a vertically aligned graphene on carbon fiber electrode, upon which metal oxides were deposited to obtain ultra-high energy density anode and cathode. A high-strength multilayer carbon composite assembly is fabricated using an alternate layer patterning configuration of epoxy and polyacrylamide gel electrolyte. The energized composite delivers a high areal energy density of 0.31 mWh cm?2 at 0.3 mm thickness and showed a high tensile strength of 518 MPa, bending strength of 477 MPa, and impact strength 2666 J/m. To show application in EVs, a toy car body fabricated with energized composite operates using the energy stored inside the frame. Moreover, when integrated with a solar cell, this composite powered an IoT (interne of things) device, showing feasibility in communication satellites.

Abstract: Energized composites include vertically aligned graphene on carbon fibers (VGCF). The VGCF enhances surface area available for charge storage, acts as templates for depositing other charge storing materials and provides stability for a minimum of 100,000 discharge cycles. The final storage device is in the order of high strength carbon fiber matrix with active material, glass fiber separator with polymer electrolyte and another carbon fiber matrix with active material. To achieve higher voltage or current, devices can be connected in series or parallel, respectively. The whole structure is made into a structural component by infusing epoxy resin. An alternating pattern of energy storage devices allows for the epoxy resin to seep through the whole structure and strongly bind them to make a monolith multifunctional composite.

Abstract: A system is disclosed for rendering a split multimedia content stream associated with a single program among networked playback devices in sync with each other. Splitting multimedia content allows, for example, two viewers of the same movie to hear the audio track in different languages, or presentation of related program information on a second screen. A presentation method disclosed ensures that the same program can be played in full or in part on multiple devices while maintaining audio and video synchronization among the devices. In one embodiment, synchronization is achieved by monitoring network latency and client system latency, and then incorporating latency information into a program clock reference (PCR) signal for transmission to a secondary playback device.

When the determined voltage of the photovoltaic panel system exceeds the voltage limit, the inverter frequency can be controlled for keeping voltage of the photovoltaic panel system substantially at the voltage limit.
