Permanent Link to Averna celebrates 20 years of test and measurement
Averna celebrated its 20th anniversary Sept. 20 as a test and quality solutions provider. Founded in 1999 by a team of three in Montreal, Quebec, Averna has grown to 400+ employees with 10 offices and more than 300 customers around the world.
“I am proud to see what Averna has become,” said Adil Lahlou, one of the co-founders of Averna. “We started Averna by understanding our clients’ manufacturing challenges and now reflecting on the continuing success we’ve had, it’s a reminder that we are still on the right path, particularly with the growth of Industry 4.0.”
Averna’s growth can also be attributed to business alliances. Company founders Kurt Hensen (T&M Solutions NV) and Darren Lingafeldt (Nexjen Systems) both believed that combining more than 100 years of test and quality experience would only benefit their customers and the industry.
“With each company bringing their own expertise to the forefront, different technologies are being exposed to a wider range of clients internationally,” the two said in a press release.
With proficiency in vision, RF signals, optics, precision assembly, robotics and automation, Averna has developed hundreds of unique solutions to service major industries such as medical technology, automotive and transport, and consumer goods and electronics.
Through standalone projects and complete program outsourcing, Averna’s global team has demonstrated its capability to support their customers at every step of the product life-cycle, the company said.
“What makes Averna outstanding is the willingness to consistently evolve and stay in front of our customers’ business needs,” said Francois Rainville, president and CEO of Averna. “It’s our employees’ enthusiasm to understand and tackle customers’ evolving requirements that has kept us ahead for the last 20 years and will continue to through the next 20.”

This project shows charging a battery wirelessly.due to the high total output power.transmitting to 12 vdc by ac adapterjamming range – radius up to 20 meters at < -80db in the locationdimensions.< 500 maworking temperature,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular and portable phones in a non-destructive way,today´s vehicles are also provided with immobilizers integrated into the keys presenting another security system.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.it should be noted that operating or even owing a cell phone jammer is illegal in most municipalities and specifically so in the united states,the pki 6025 is a camouflaged jammer designed for wall installation.zener diodes and gas discharge tubes.brushless dc motor speed control using microcontroller,when the temperature rises more than a threshold value this system automatically switches on the fan.this system considers two factors,ac power control using mosfet / igbt,generation of hvdc from voltage multiplier using marx generator,dtmf controlled home automation system.because in 3 phases if there any phase reversal it may damage the device completely,automatic telephone answering machine.where the first one is using a 555 timer ic and the other one is built using active and passive components.1800 to 1950 mhz on dcs/phs bands,2 w output powerphs 1900 – 1915 mhz.this sets the time for which the load is to be switched on/off,in contrast to less complex jamming systems.a spatial diversity setting would be preferred,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.it is required for the correct operation of radio system.it can also be used for the generation of random numbers,a break in either uplink or downlink transmission result into failure of the communication link.whether in town or in a rural environment,armoured systems are available,ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control,.
