Hardware
Below is a list of our key hardware services, do please contact us if you have a particular requirement that isn't covered.
Analogue Design
All electronic circuits are essentially analogue, including digital circuits as every logic gate is made up of transistors which are analogue devices.

Battery Powered Devices
Designing a product or system to operate efficiently on batteries requires very careful design of the circuits, including radios and peripherals, any embedded software, device drivers or programmable logic devices and of course the battery management itself.

Cameras, Video & Audio
Our experience in this area is extensive, from vision mixing desks, routing systems, standards conversion, noise reduction and digital cinema - demonstrating one of the first presentations of Digital Cinema in 1999.

Chemical & Gas Sensing
Any automated system is only capable of responding to changes that it can sense. We have a broad and in-depth knowledge of sensors and the circuits and algorithms needed to make the most of them.

Communication Links
Communication links are everywhere, between people, electronic products and systems, across networks and the internet

Computers & Microcontrollers
We have designed with almost every type of computer sub-system or microcontroller. From low power battery operated microcontrollers intended to last for months or years without a battery change, to high speed parallel computer sub systems used in robotic surgery where safety and fault tolerance are paramount – we have designed every system.

Digital Signal Processing
Digital signal processing is a large field but broadly the types of processing applied to signals involve filtering, measuring, compressing and signal conditioning.

EMC & Radio Approvals
To enable CE or FCC marking of electronic devices, the devices will need to be tested for electromagnetic compatibility (EMC). EMC testing checks that an electronic device does not emit electromagnetic energy above a prescribed threshold and inadvertently interferes with other electronic devices. Similarly, it checks that the electronic device is not susceptible to certain levels of electromagnetic energy.

Fault Tolerant
Prior to developing medical devices, we worked in the design and verification of aerospace components and systems. Consequently, we have extensive experience in design for safety critical and mission critical systems.

FPGA, CPLD & HDL Design
Field Programmable Gate Arrays (FPGAs) and Complex Programmable Logic Devices (CPLDs) are programmed or configured using a Hardware Description Language (HDL). The languages we normally use are VHDL and Verilog. In addition to FPGAs and CPLDs we have significant expertise in designing full-custom and semi-custom integrated circuits (ICs) or microchips, known as Application Specific Integrated Circuit (ASIC) design. We can take your digital and mixed signal design from layout to fabrication.

Human Interfaces
We use a whole range of interfaces to interact with devices and systems. Common interfaces are keyboards, mice, monitors, touchscreens, buttons, pens, speakers, cameras, and microphones.

Internet of Things (IoT)
Internet of Things (IoT) refers to the growing network of ‘smart’ objects or devices that connect over a local network or the internet. The purpose of this network of devices is to exchange data typically devices in the network can respond to each other, to people, other networks, machines, the environment, or a combination of any of these.

RF Circuit & Antenna Design
Westwood Rock was founded by engineers who already had RF and high-speed digital experience from working with Radar, maritime radio, broadcast, and consumer applications and had been published in the IEEE MTT-S International Microwave Symposium. They had also taken their designs through EMC testing and CE marking.

Thermal Management
Thermal management influences product and system reliability but some thermal management techniques can impair usability or aesthetics. It is imperative that the full design team work together to develop effective thermal management.
