Title: Wireless mutliplex data transmission system

Abstract: A method and apparatus for wireless transmission of data through a communications channel between at least two local data sensors (for example automotive diagnostic data sensors or NVH sensors), which may include a primary data-processing function, and data-processing function (for example a PC) to receive data therefrom. The system provides for asymmetrical division of the communications channel on a frequency or time-division or packet-switching basis so that the corresponding asymmetrical data transmission requirement of the local data sensors are matched to the capacity of their respective sub-channels whereby a single channel is capable of transmitting all the required data. A particularly practical application is to noise vibration harshness analysis of wireless-transmitted data from three-dimensionally spaced NVH sensors enabling special pinpointing of vibration sources in automotive warranty analysis studies.









Disclaimer: The promise of Apex Standards Pseudo Claim Charting (PCC) [ Request Form ] is not to replace expert opinion but to provide due diligence and transparency prior to high precision charting. PCC conducts aggressive mapping (based on Broadest Reasonable, Ordinary or Customary Interpretation and Multilingual Translation) between a target patent's claim elements and other documents (potential technical standard specification or prior arts in the same or across different jurisdictions), therefore allowing for a top-down, apriori evaluation, with which, stakeholders can assess standard essentiality (potential strengths) or invalidity (potential weaknesses) quickly and effectively before making complex, high-value decisions. PCC is designed to relieve initial burden of proof via an exhaustive listing of contextual semantic mapping as potential building blocks towards a litigation-ready work product. Stakeholders may then use the mapping to modify upon shortlisted PCC or identify other relevant materials in order to formulate strategy and achieve further purposes.
