Product Range

Based on the motto "We provide solutions when off-the-shelf products or catalogue components don't fit" here it is not easy to show simply a list of products, especially since most developments are legally committed to non-disclosure agreements. Instead it is more helpful to mention the key technologies and expertise, by which Efopti Systems is able to best support its customers:

The size of our products are usually table-top or smaller. Quite often they are small sub-systems to fit into much bigger units, the end-products of our customers. These end products might be even large industrial production units, where our sub-systems act as supporting e.g. the test & measurement tasks.

Development and Production Steps

Our Main Markets

The most effective way of presenting the product range of Efopti Systems is to categorize the markets our customers are participating:

The typical path of getting in contact with clients of these markets is by requests of them to us, regarding solutions to upgrade or improve their existing products. Or by requests regarding their new product designs, integrating cost-efficient sub-systems, which are not available off-the-shelf.
Cost-efficiency is achieved by tailoring our systems exactly to the customers needs. By this way the additional development costs are compensated by lower production costs of the product.

Even though a lot of integrated circuits are existing in this field, the need for applying discrete and hybrid solutions is very common.
So it is almost a daily routine to run developments on specific

The topic Sensor Technologies mainly includes understanding of the internal working principles and the correct application of MEMS-based integrated components.
Such sensors are e.g.

The most critical part of using these sensor is of course the data acquisition and analysis part by specific software. The software is typically running on μControllers in embedded systems. So restrictions in memory and computation power are apparent, especially in small units with rechargeable batteries.

The Optical Technologies are the foundation of the Photonics Technologies, mentioned in the next topic. Without solid knowledge in this field, a lot of mistakes and unstable installations are inevitable when designing Laser-based systems.
Nonetheless these technologies are not simply of the bread-and-butter type. For example the interferometry can be applied for very sophisticated measurement systems with spatial resolution down to nanometers, much lower than the wavelength of the light it is using.

A lot of non-invasive medical examination methods are based not on X-rays or ultrasound, but on Photonics. Their main advantage is the low cost and ease-of-use. It is one of many successful examples of using light for non-contact measurements and remote sensing.

The topic itself is highly specific and needs lots of experience for successful design and application. The Laser and detector components are highly sensitive to electrostatic discharges and fast current transients, which demands for special electronics. The low-noise amplification of very small currents is required for reading-out of sensors and detectors.
Optical fibers and connectors require special mechanical handling, which is not general knowledge.

Almost every of our products contain some sort of devices from the following list. They are required for acquisition of data of any kind, for initial filtering, aggregation, storage and analysis inside the product.
As well they are required for transmission of the data and information to the embedding unit. In addition any information of the embedding unit for controlling and signaling to our product is received and processed inside the Embedded System on the list:

Even though the manufacturers of the μControllers are supporting the embedded software developers with many tools and template code, to achieve fast and memory-efficient code, we are developing own optimized software.
This especially holds for the operating system (OS) part of the μController code, which is 100% own IP.

Given the complexity of the μControllers with a huge number of internal interface units with many configuration options, it is inevitable that interfaces will generate anomalies under certain operating conditions. This holds e.g. for the SPI, I²C, UART interfaces, or the DMA channels. Nonetheless, with many years of experience in working with many different kinds of μController families, we developed code to avoid the known anomalies.

Experience in designing and manufacturing Wireless Units is required regarding
⇒ Materials selection (affecting radiation propagation)
⇒ Selection of data transmission protocols (affecting transmission bandwidth, security and encryption)
⇒ Balancing transmission range versus power consumption, e.g. by applying data payload coding and compression based on own IP
We are specialized in:

These techniques are applied as a combination of special electronics and software for analyzing the signals:

This kind of software is mainly running on our μControllers inside of embedded systems. It has to be optimized for very fast results without consuming too much RAM memory.

An initial real-time analysis of raw data of sensor output is necessary for example in medical devices. To achieve high temporal resolution, high sampling rates of the detectors are applied. These sampled data is impossible to be transferred wireless to the host without a huge power consumption. Instead it gets analyzed, and the final result (e.g. a heart rate) being transmitted wireless at a much lower rate.

To support clients in processing the data received from our products, we provide assistance with operating Linux-based server software. And we provide own software developments, especially for subsequent advanced analysis of real-time data of our systems.
