Business Results

PSI - Probe Science Inc. helps you solve business, technical, and intellectual property challenges in the wireless technology market.  We have a long history of successful client engagements across a variety of industries including healthcare, public sector, and military technology.  We do not sell wireless products or services to end-users, we work with OEM partners to deliver wireless technology to the market quickly and profitably.   Bring us your project ideas and let us help you accelerate time to market, reduce risk, and increase ROI.

Here are some example client engagments and some issues we have helped to solve:

  • Technical Design Challenges: Designed the first system on the market to wirelessly communicate information through sealed titanium enclosure for an implanted medical device.
  • High Cost of Technology: Replaced a $2500/channel wireless system with custom $230/channel system, reducing the total cost of the system by $16,000 per unit.
  • High Licensing or OEM Costs: Reduced per-unit technology licensing fees for a product from $100 to $1; reduced overall COGS from $300 to $82 while improving performance.
  • Regulatory Approval Issues: Designed systems with existing modules and managed the FCC approval processes to get product to market in timely fashion.
  • Legacy Technology Conversion: Reverse-engineered and redesigned legacy electronic components with low or no availability, reducing supply risk and cost while improving performance.
