Cabin Air Sensor Solutions (CASS) has developed a sensor able to detect in real-time, individual poisonous compounds that can be present in an aircraft cabin. Until now it has not been possible to detect these poisonous compounds to establish and prove their presence. 

 

Circad developed the PCB design for an initial bench device, and then integrated these embedded systems into a hand-held device, and developed the prototype electronics for collecting and presenting the data through custom designed software. 

 

The initial handheld unit design and detection capability has been witness tested and verified using Gas chromatography–mass spectrometry (GC MS) by the National Physical Laboratory in Teddington, UK for the detection of low-level TBP in ‘real-time’. 

The Raspberry Pi is a credit card sized Printed Circuit Board that is actually a stand alone computer. The Pi enables enthusiasts to quickly develop prototype electronics running code that they have written. Although the Pi is a fantastic product, it is intended to be an educational tool, and not part of a commercial product. Many of these prototype PCBs could be commercially viable products, however entrepreneurs soon discover a couple of problems when trying start manufacturing. 

One of our larger projects was to develop the electronics design for a fully digital secure door entrance system to connect any combination of up to 945 entrance doors, flats or concierges. We were also tasked with its manufacture. 

Leading vermouth brand Martini’s latest positioning centres on the idea that time spent with friends is time well spent. They wanted to support this in a noticeable and practical way. The result was an ice cube-shaped device that anticipates when a drink is finished, uses a Bluetooth transmitter to communicate with the bar in real time and allows staff to prepare drinks in advance. 

 

CIRCAD were selected to design and manufacture the SmartCubes because of their proven track record of PCB design, and their ability for electronics manufacture in the UK within an extremely short timescale. 

Fixate's supplier failed to provide a working prototye for a competitive pitch so Circad were contacted at 6pm on a Friday evening and briefed on the technical issues. Following a rapid pcb design review, Circad resolved the hardware and software faults over the weekend & provided working electronics prototypes for a meeting in Switzerland at 9am on the following Monday. 

A referred customer was suffering continuing problems with power supply failure and an inability to pass the Electrostatic Discharge tests (ESD tests) within Electromagnetic Compliance, compounded by supplier interface issues. Circad undertook a rapid pcb design review to diagnose the issues and propose solutions. 

Circad has been retained for the electronics design, development and electronics manufacture of the medical electronics systems for a device that allows the transport and preservation of warm livers for up to 24 hours prior to transplant. 

The Android operating system is a well established platform for tablets and mobile phones. As as Android developer, Circad can connect this powerful operating system directly to your electronics, giving your customers an easy and familiar user interface. 

A DALI (digital addressable lighting interface) ballast controller allows a building management system to automatically control lighting depending on the time of day, ambient light and building occupancy. They are popular for controlling the lighting within bathrooms and corridors of large buildings where a cost saving can be made by not lighting un-occupied rooms.  

 

Circad were asked to create a PCB design for a DALI ballast that was capable of driving three 10 Watt LED’s from the same node, meaning that a building could be lit by a single network. Installation of the product was required within 5 weeks from the request. 

The Cirque d'Hiver ("Winter Circus") in Paris, has been a prominent venue for circuses, concerts and other events since 1852. As part of their spectacular 2013 presentations they wanted to produce a waterfall that could create images in the falling water. Circad were retained to develop the electronics design to control these images. 

Circad were asked to develop the electronics design for an inject refilling system that was installed in over 1000 US retail stores. The system allowed customers to have their own cartridge filled and tested within minutes at a fraction of the cost of a new one. 

If you want your PC to interact with equipment in the "Real World" from its "Virtual World" you need our Relay Controller that was originally designed in response to a customer request. Circad designed, started electronics manufacture, and delivered the first working product within two weeks from the initial request asking if it was possible! 

Councils need to know how many visitors they have to each of their libraries, but currently a member of staff manually counts visitors then emails results. Circad were asked to automate the process and the central collection of results through a turnkey electronics design and electronics manufacture contract. 

Circad were asked to develop a system for a motor home manufacturer that allowed a motor home owner easy long distance remote control of their heating. The electronics design used SMS messages sent to and from the mobile home to control the heating. 

Modern TV programmes have disability access for the blind, including audio description. The program guide however still requires menu navigation using a remote control. Circad were asked to develop the electronics design for a product that would retail for under £100 to allow the Electronic Program Guide on SKY to be used by a blind person.
