Highlighted below are examples of our numerous successful projects in research and development. Several selected projects are showcased in PowerPoint slideshows in pdf format. The vast majority of R&D programs performed by BTR have been confidential/proprietary efforts for clients; most of these cannot be summarized or detailed here. The intellectual property and/or trade secrets of new and existing technologies are invaluable to the success of our clients. BTR adheres stringently to Non-Disclosure Agreements that BTR enters with its clients. The examples provided at our web site are either BTR’s internal R&D programs or clients’ programs for which BTR has been given permission to publicize or only non-confidential general information is disclosed.
