"We build your product so you can build your business"

Case Studies

Think Logic has selected a small sample of the products we have helped develop over the years. In order to showcase our skills and the product's purpose (rather than the products themselves), specific details relating to the application/implementation are omitted, and images are limited to CAD renderings only. Please contact us if you would like to discuss any of the projects below in more detail.

OSDP Adapter

Background: The Open Supervised Device Protocol (OSDP) is a standardised communication protocol gaining traction in the physical Access Control industry. Managed by the Security Industry Association (a trade association based in the USA for global providers of security solutions), it is continually evolving through the efforts of various members of SIA’s OSDP Working Group; and is even in the process of becoming recognised as an ANSI standard in the USA. Intended to facilitate greater interoperability between Access Control devices from different manufactures, OSDP offers increased security over the traditional Wiegand protocol through AES-128 encryption, and continuous monitoring of devices through frequent polling from the Control Panel.

Product Brief: Think Logic's OSDP Adapter is a configurable device that allows up to 2 Wiegand keypads/card readers, 3 digital outputs, and 5 digital inputs to be addressed by an OSDP Control Panel (CP) as a single OSDP Peripheral Device (PD). Measuring less than 70mm on its longest dimension, the OSDP adapter is designed to fit inside a wall cavity and connect directly to the cabling of electric strikes and readers. Not only does this help access control providers transition from existing Wiegand systems to OSDP (without costly upgrades to existing keypads/card readers), it's small size also reduces installation time and costs by avoiding the need to extend cables during installation, and allows the installer to run 4 cables (power + OSDP) from the Control Panel (rather than up to 30 cables to achieve the same functionality).
If the existing Control Panel does not support OSDP, a second OSDP Adapter may be placed at the Control Panel and configured to map the inputs, outputs, and card reader data back to their original digital & Wiegand formats. This allows existing non-OSDP Control Panels to gain the benefits of an OSDP connection without major upgrades to the Control Panel.

If you are an existing organisation looking to incorporate Access Control (or OSDP) into to your product range, seeking a customised modification of the adapter to suit your specific needs, or simply interested in finding out more about Think Logic's OSDP Adapter please contact us to arrange a discussion.

DC Solar Power Converter

Background: Consumer interest and investment in renewable energy is continuing to grow globally, and the number of solar installation companies in Australia has grown considerably over the past decade. An application for an off-grid solar array was identified as a means to not only help consumers increase their utilisation of solar energy, but also to help Australian solar installation companies continue to remain profitable as various government rebates and trading schemes are wound back in the coming years.
Product Brief: Think Logic developed a 2kW DC-DC converter as a proof of concept to investigate the suitability of an off-grid DC system for a specific application typically powered from AC mains. The application lends itself well to being powered from a DC source, and thanks to some unique algorithms and implementation insights, allows the load to be powered just as effectively from DC as it is from an AC power source. The proof of concept was developed to answer technical and market-driven feasibility questions, with the next phase of commercialisation currently under consideration.

Measurement Verification Device

Background: A particular industrial process requires an operator to use a hand-held data logger to measure and record milli-volt level signals. These mV readings are then used as inputs in the control process of the entire system. Optimum system performance is therefore dependent on the integrity of the data gathered. Due to the nature of this specific industrial process, there are several factors that affect the integrity of the readings, and the existing loggers used provide no feedback regarding the accuracy of these measurements.

Product Brief: This product connects in series with the existing hand-held data logger, and measures key metrics known to be required for accurate readings in this specific industrial process. The product only allows the logger to gather data if the requirements of these metrics are satisfied.
Field trials showed the device also measured the mV level signals with very high repeatability and reliability, and as such the second revision was designed to include logging capabilities, making it suitable for stand-lone operation whilst also maintaining the ability to complement the existing data logger.
This product is powered from a rechargeable lithium battery, and has additional R&D features built in to detect other problems known to affect system performance in this industrial process.

Automated Test Fixtures

Background: Our client is a global supplier of reliable, mission-critical devices in the Medium Voltage power distribution sector. They rely on stringent quality management practices throughout their production facilities in order to minimise in-field failure of their equipment, and maintain their reputation as a provider of high quality, reliable devices to the industry.
Part of their quality process is to test every Printed Circuit Board Assembly (PCBA) at the point of manufacture, in order to ensure that every PCBA used in their products is of known and acceptable quality.
The automated test fixtures used to verify such mission-critical devices must be equally robust and reliable, as taking a fixture off-line for repair often leads to costly delays in the manufacturing chain.

Product Brief: Working with our client’s software provider, Think Logic has designed, built and commissioned several Functional Circuit Test (FCT) fixtures over the years.
Our fixtures generally utilise spring-loaded pins to access test points on the PCBA, but we have also designed fixtures that interface with the Device Under Test (DUT) via pluggable connectors on the DUT itself.
Needless to say, a complete and thorough understanding of the DUT is required in order to design an FCT system.
