Wireless Electronic Lock

Challenge

Create a remote controlled, wireless, keyless lock for use with wood furniture, desks and cabinet applications.  The battery powered transmitter must have a 10 digit keypad and be small and unobtrusive.  The battery powered receiver/locking mechanism must be small enough to fit into any drawer or small cabinet.

Solution

Microchip PIC SOC (transmitter) and receiver chip (receiver), PCB level antennas, off-the-shelf batteries, Microchip communication protocol, PIC assembly code and Microchip MPLab were used to create this low power, robust and secure solution.

Summary

Tecnova was asked to develop an FCC approved, small form factor, battery powered, wireless locking device for home-office wood desks and cabinetry.

Product Design: Designing for Reliability, Regulatory Standards, and Manufacturability

Challenge

Refine a proof-of-concept design to optimize product reliability, compliance to regulatory standards, and manufacturability.

Solution

Develop a system of circuit boards and interconnections for cost effective integration and manufacturing while adhering to industry and regulatory standards.

Summary

Assessing the viability of a product idea can be difficult. The process often begins with a rough design sketched on paper. As the research and development phases of the project move forward, one or more proof-of-concept prototypes are often required.

Embedded Electronics: Portable Chemical Analyzer

Challenge

Create a low-cost, handheld battery powered fluorometer for use in laboratory settings to measure trace chemicals in industrial reverse osmosis treatment systems.

Solution

A custom designed pen fluorometer with a membrane keypad and LCD display, based on the Texas Instruments MSP430F427 16‑bit ultra-low-power microcontroller.

Summary

Industrial reverse osmosis (RO) water treatment is used to purify process water by removing impurities. As pressurized raw water enters the RO system, a small amount of pure water passes through a filter membrane.

Commercial Design: Low-Cost, Medium-Duty Electronics for Plasma Steel Cutting

Challenge

Develop a low-cost, robust, and lightweight solution for medium-duty steel cutting needs for light-duty construction and do-it-yourself (DIY) applications.

Solution

A custom circuit board based on the Microchip PIC16F870 processor monitors status and controls power and cooling to the plasma torch.

Summary

Plasma cutting of sheet and plate steel offers several advantages over other means. Sawing or grinding material produces metal chips.
