Where should I look to see if any funding is available for an industry-based research to attend and present at academic conference?
Unless you are invited to present as a keynote speaker, you're probably out of luck for getting sponsorship from conferences to present.  The expected cash-flow is generally in the other direction: conferences ask industry to donate money that supports the travel of academics.

Many companies, however, have internal "professional development" programs that allow employees to apply to use internal money to attend conferences, even if it is not directly connected with their current job responsibilities.  Check and see if your employer has an option of that sort: most large high-tech companies have some sort of formal program, and many small companies have informal options.  

Another option is to see if you can convince your employer to run a marketing or recruitment booth, if the conference is within the company's general scope of interests (or public relations outreach).  Then, even if it's not within the scope of your current duties, you may be able to "pay your way" on the trip by organizing and spending part of your time manning the booth.
