摘要:
In an aspect of the invention, a process to make a nanowire array is provided. In the process, silicon is deposited onto a conductive substrate comprising an organic material and optionally a conductive layer, thus forming a silicon-containing layer. Nanoparticles are deposited on top of the silicon-containing layer. Metal is deposited on top of the nanoparticles and silicon in such a way that the metal is present and touches silicon where etching is desired and is blocked from touching silicon or not present elsewhere. The metallized substrate is contacted with an etchant aqueous solution comprising about 2 to about 49 weight percent HF and an oxidizing agent.

An improved system and method of capturing, transmitting, rating (exclusive content), continuously playing, selling and advertising listener and/or viewer data from vehicle Original Equipment Manufacturers (OEM) equipped infotainment systems capable of receiving and translating live broadcasts for Analog TV, Digital TV, HDTV, Satellite TV, Satellite Radio (SIRUS/XM), AM, FM, HD, DRM, UHF, VHF, Shortwave, Internet Podcasts and Bluetooth coupled media is described herein. The In-vehicle Listener and Viewer Data Capture System (LVDCS) is capable of recording, collecting and transmitting audience measurement data (from automobiles or other vehicles), using only the vehicle's OEM equipped communication network, including viewing and listening data for all audio and video content derived from the Infotainment System Module (ISM), Audio/Video Control Module (A/VCM), touchscreen or vehicle radio. The scope of viewing and listening data collected as well as communication method are unique to the LVDCS.Additional unique features of the LVDCS are In-Vehicle Listener and Viewer Continuous Play Feature function and Radio Data System (RDS) Interactive Bubble Advertising. The In-Vehicle Listener and Viewer Continuous Play Feature is a Method of continuously playing an Over The Air (OTA) transmission including Analog TV, Digital TV, HDTV, AM, FM, HD, DRM, UHF, VHF and Shortwave broadcast, by transitioning to the live internet broadcast stream, via either a processor or LVDCS software equipped on the vehicles Gateway Module (GWM), ISM or A/VCM, when the strength of the OTA signal drops below a pre-defined value, the internet stream will transition to that station. Conversely, when the OTA signal reaches a pre-defined value, separate and greater than the value of the transition from the OTA signal to the internet stream, the converse transition from internet stream to OTA will take place.RDS Interactive Bubble Advertising is a Method of Advertising onto an ISM, A/VCM, touchscreen or vehicle radio by overlaying RDS Radio Text (RT) data, transmitted Over-The-Air (OTA), included in the LVDCS for interactive display. RDS data specific to advertising segments, or in between broadcast segments, transmitted OTA and received by an ISM, A/VCM, touchscreen or vehicle radio onboard vehicle touchscreen or vehicle radio will be read and processed via an onboard processor and the LVDCS to execute protocols to display Interactive Bubble Advertising. Visual display includes interactive location map, logo, symbol, emoji or hyperlinked media.RDS RT data triggers the start and stop of the Interactive Bubble Advertising by transmitting an encoded identifying bit to authenticate the transmission. Encoded identifying bit is read and processed via the onboard processor or pre-loaded software or firmware downloaded onto an ISM, A/VCM, touchscreen or vehicle radio. Post authentication of the OTA RDS RT transmitted identifying bit, Interactive Bubble Advertising will begin. Interactive Bubble Advertising will then be used to display Advertiser content. Advertiser content will be coupled with display interface with the LVDCS for use on the ISM, A/VCM, touchscreen or vehicle radio, including interactive map displays, blue tooth enabled synchronization of dialing a displayed number or hyperlinking web based content.
