About
Pure Engineering was founded in 2006 as a consulting and design firm for small projects and ideas. In 2014, the company was officially established as Pure Engineering LLC due to the significant growth of our consulting work and products. Our services include strategic planning, product development, and architecture design. We use engineering principles to assess the feasibility and suitability of technology for a given design. If a project requires more than just a design plan, we can create a proof of concept to help visualize the product and a prototype to test its functionality before moving to manufacturing. We also offer subject matter experts to help solve design challenges and unproven technology development for clients who want to stay at the forefront of innovation. Our goal is to provide comprehensive engineering solutions to help our clients bring their ideas to life.
IoT
The Internet of Things (IoT) is a major area of focus for us at Pure Engineering. We have been developing IoT systems for many years, specializing in low power systems that run on batteries and the efficient movement of data across these systems to servers. Our team is experienced in working with a variety of wireless technologies to support any application. Whether you need help with strategic planning, product development, or technical expertise, we can provide the support you need to bring your IoT ideas to fruition.
Bluetooth Low Energy
Bluetooth Low energy(BLE) is an explosive new technology in the marketplace today. We have extensive experience making sensors that connect to modern cellular phones and computers. We have proven designs that run from several uWatts of power enabling your device to run for years without a battery change. We are familiar with the entire BLE stack and can make custom protocols using COTS hardware.
We have experience with the following BLE micro-controllers:
Nordic nrf5x series
TI cc26xx series
Cypress PSoc 4 BLE
STM BlueNRG
Dialog SmartBond
and Others
Thermal Sensor Integration
We have extensive experience with FLIR Lepton Thermal Camera. We were the first to bring to market a simple to use breakout board that enabled video capture from micro-controller development boards. Several thousand systems have been shipped to date.
Radiation Sensors
We are intimately familiar Radiation Sensors. We have designed fully custom solutions for the electronics for several detector materials.
Spectrometer Sensor Integration
The Hamamatsu C12666MA and C12880MA Spectrometer are game changers in terms of size and functionality for a spectrometer. We are supporting this sensor with breakout boards and sample firmware and software to enable the DIY crowd to make sensors to improve the world and how we see it.
Android Application Development
Android is a popular operating system for mobile devices such as phones, tablets, and netbooks. It was developed by Google and is based on the Linux kernel and GNU software. There is a large community of developers who create applications that extend the functionality of Android devices using the Java programming language and Google's Java libraries. At Pure Engineering, we have extensive experience in developing Android applications and have seen some of our apps reach over 100,000 downloads on the Google Play Store. In addition to application development, we have experience with the Android Open Source Project (AOSP) source code and have made custom modifications to it, including the creation of custom ROMs and tools. Our team is equipped to handle a wide range of Android development projects.
Software Defined Radio Hardware and Firmware
We have extensive knowledge on designing hardware for Software Defined Radio (SDR) systems as well as writing the embedded software to make them run. We are aware of noise, cross-talk, signal loss, and impedance matching that are critical in making a working system.
Ground Penetrating Radar
With a number of published articles on GPR, our staff has contributed to the GPR community and familiar with building, testing, and evaluating GPR systems. In addition to GPR, this research has carried over to sonar image reconstruction as well. A number of signal processing techniques have been developed as well that can do target identification and classification based on the signature response of and unknown target. These signal processing techniques can be applied to a number of different applications. see paper
Development Back-end
In order to support a wide range of solutions, we have had to understand the tools to make such systems. We are focused on supporting the GCC tool chain for all embedded development. We have experience with a number of different micro-controller families ranging from the AVR, AVR32, ARM M0, M3, M4, A8, PSOC5 and A9. Our back-end support also includes revision control management, selection, setup and maintenance. We are familiar with a number of revision management tools such as SVN and git. We understand project management and the tools needed to excel.
Cloud Back-end
We do full-stack development to support many applications but our focus is cloud development to support a million devices on a single server by developing server code like firmware. Our focus is using modern standard protocols such as gRPC and REST to supporting the exchanging of data to clients, and custom low overhead encrypted communications to sensors. When it’s the right solution we use graph databases to have very efficient queries that scales linearly and time series databases for archive and analytics. Our preference is to develop docker based deployments with pre-configured load balancing and proxy services, but we can utilize services from AWS, Azure, and GCS when it is the prefered solution.
Front-end
Our team can build native UI's for android, iPhone, windows, MacOS, Web. We prefer to develop cross platform web based technologies that target multiple platforms to simplify development and user experiences.
