Tucson Embedded Systems (TES) has performed many projects for the commercial industry, including medical devices and various controllers. Please contact us for more information about our capabilities and how we can help you.

Previous TES Commercial Projects

The brief descriptions below are a sample of some of the projects that TES has successfully accomplished.

Medipacs Digital Controller

Technology advancement has increased the need for fluidics applications that can deliver small volumes of liquid in a controlled, accurate method.  In healthcare, sophisticated liquid drugs require affordable and accurate delivery devices that can go home with the patient.  Aerospace and automotive require accurate fuel injection pumping systems. Future high speed electronic components will require water cooled devices using sophisticated fluidics. Medipacs has designed and has patents pending for pump technology that can address these needs by offering improved accuracy and reliability at a fraction of the cost of today’s devices.

In 2006, TES teamed with Medipacs to develop the first Programmable Disposable Infusion Pump. Innate to the design, the Medipacs pump relies on the fundamental mechanism of pumping by “known” displacements for reliable and accurate flow. Additional safeguards were necessary to ensure that the desired flow rate occurred within a stated tolerance. 

Automotive Pressure Tester

TES helped develop the gas pressure tester controller for California's smog control program.

Piezo Circuit Design

TES helped Piezo Energy Technology on their project for the National Science Foundation grant, "Augmenting the Lifetime of Implantable Batteries".

This Small Business Technology Transfer (STTR) Phase I project addresses the feasibility of harnessing the internal biomechanical forces using piezoelectric transducer technology to power implanted devices such as cardiac pacemakers. The project will advance the development of in vivo energy harvesting devices as power sources in general for medical appliances in human and veterinary health sciences.

The research seeks to increase the longevity of implanted devices that require battery power for function. The project will alleviate the need for repeated surgeries for battery replacement, increase the functionality of the implant by providing more diagnostic output and burst mode power and to increase the overall reliability of the implant due to the back up system in place.

Solar Concentrator

TES supported a large industrial company in their creation of a High Concentration Photovoltaic (HCPV) power conversion system designed to capture electricity from 500 suns of power. In order to achieve high efficiency power conversion at significant power output, solar energy is concentrated into a closed cavity (PVCC) containing PV cells and photon recycling design features. The initial system prototype demonstrates a system which will ultimately be scaled to a multi-MegaWatt system for conventional utility-generated electricity on a wholesale basis. TES constructed the subsystem, conducted systems integration, and safety critical testing. TES' HCPV Project Assembly, Integration and Test tasks served as the principal method for gathering engineering data to evaluate the overall viability of this concept for commercial use.

SF Project Track Software

To support the rigors of engineering in a DoD environment, TES designed our own project management and manpower activities system called SF Project Track. This system has been DCAA approved for government work and has been utilized on all TES contracts.

Earned Value Management (EVM) is our preferred management technique for measuring project progress. EVM combines measurements of scope, schedule, and cost in a single integrated system. EVM provides an early warning of performance problems, prevents scope creep, communicates objective progress to stakeholders, and keeps the project team focused on achieving progress.  Tucson Embedded Systems developed Project Track in 1997 as the quintessential EVM system.  Projects are defined by charge categories (e.g., CLINs) in a hierarchical Work Breakdown Structure (WBS).  In order to assign value, Planned Value (PV) hours are assigned to each WBS and to resources.  The hierarchical arrangement allows users to view details or summaries at all WBS levels assisting managing tasks and hours. The combination of tasks and hours defines scope.

SF Project Track implements the employee timesheets on-line system, and employees will complete their timesheets daily and submit them weekly.  In this manner, progress can be measured on a day-to-day basis in near real-time.  Program managers can review and manage project EV weekly or daily.
