IoT + sensors – for over 23 years!
Our engineers designed their first sensor 23 years ago, and since then there have been projects for: accelerometers, speedometers, protractors, material humidity and temperature meters. As the Internet of Things has grown, we have developed our expertise in this field, especially in wireless transmission using LTE/WiFi and low-power technologies, including in particular BLE, LoRaWAN, SigFox and ZigBee. It is worth noting that our project team has an excellent understanding of Power Solutions, in particular the design of switching and linear power supplies, alternatively the selection of off-the-shelf inverters, and in the case of power supplies based on secondary cells (batteries, rechargeable cells) or the design of BCM/PCM circuits, we know the relationship between the chemistry of the cell and the safe deformability of the cell. This is crucial for the design and subsequent success of the product in the market. We have direct contacts with manufacturers of cells or customised inductive components. We are familiar with the design considerations resulting from the use of diverse primary cell chemistries, (single use) not only lithium-ion, but also lithium-thionyl, lithium-iron or lithium-manganese, allowing years of operation on a single set of cells.
3 million miniature domestic appliances
The miniaturisation of household appliances on the one hand and their increased saturation with electronics on the other has brought a whole new class of appliances to the market. Miniature household appliances must be as durable as their large-scale counterparts, be attractively priced and offer that unique, eye-catching something that classic kitchen utensils do not have. An egg timer, a milk frother, an electric kettle, a smart blender, a wireless oven thermometer, water-filtering jugs to make working in the kitchen easier, are therefore increasingly gaining buyers. The challenge with this type of design is the energy-saving aspect, as they are mostly mobile, cell-powered devices. Another difficulty to overcome is the elimination of human health risks due to frequent contact with food and the high toxicity of electrolytes from the cells. The commercial success of the product must also be assumed from the start of the project, so that quality control aspects or the elimination of assembly errors are taken into account at the design stage. Production cost is also important, which for the same application and the same scheme can be extremely different if one does not know the considerations of electronics assembly technology. Miniature household appliances, designed by our engineers, have been produced in excess of 3 million units.
Control and measuring equipment
We have designed measuring devices for a multitude of applications. Our portfolio of course includes standard devices measuring voltage, current, time, temperature, humidity, distance, weight, light and many others. What sets us apart, however, is our ability to design a fully customised device. In the past, we have enabled our customers to measure: deflection or vibration of the viaduct structure, the sway of a building, the degree to which the air filter is full/dirty, the concentration of gases in a room. We have recorded the path of a moving vehicle or object, and even calculated the sun’s position point based on GPS data alone – and for our customers we could even measure the number of needles in a haystack.
User control panels
Our design team has developed dozens of types of customised displays, including versions integrated with touchpads, and designed control panels with displays enhanced with function keys. The design took into account aspects of user comfort and durability over many years of operation.
Automatic testing machines
We have many years of experience in building automatic testing machines for ICT/FCT functionality, using a range of technologies, developing dedicated software, making mechanical and pneumatic controls and integrating them into the production line. The total number of modules tested has exceeded 4.5 million units. We also design tests of equipment supplied to us, using COBOTA, where we test the performance of keypads, vending machine panels, etc. thousands of times in a single cycle as part of repetitive activities. We have performed more than 4.5 million tests with our original testing machines.
