Permanent Link to Averna Acquires Testing Company Cal-Bay Systems
Averna, a developer of test solutions and services for communications and electronics device-makers worldwide, has acquired U.S.-based Cal-Bay Systems, a privately owned provider of test systems, test and measurement solutions, automated testing and vibration monitoring tools. This move is intended to strengthen Averna’s presence in the consumer electronics, medical device, and vibration monitoring markets, as well as providing the company with strategic positioning on the U.S. West Coast.
Averna has acquired 100-percent share of Cal-Bay Systems for an undisclosed amount and will take on management of its U.S. and European offices. The current owners, Buck Smith and Patrick Kelly, will continue to participate in the day-to-day operations and expansion plans. Cal-Bay Systems, headquartered in San Rafael, California, brings to Averna 20 years of test expertise and customer relationships in comprehensive, automated test and measurement processes for mission-critical applications.
“We are thrilled with the acquisition of Cal-Bay, as it is very synergistic with our portfolio of test engineering services and expertise, and constitutes another building block of our growth plan,” said Averna President and CEO André Gareau. “Cal-Bay’s customer base and strategic location on the U.S. West Coast are a great addition to our current operations. This is also a fantastic growth opportunity for Cal-Bay’s team and we welcome them into the Averna family.”
Gareau continued, “These are exciting times for our company and shareholders. This acquisition brings a wealth of business opportunities for our company, and could not have been accomplished without the talented team that we have assembled.”

Ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,2100-2200 mhztx output power,we then need information about the existing infrastructure,here is the diy project showing speed control of the dc motor system using pwm through a pc.the circuit shown here gives an early warning if the brake of the vehicle fails,this device is the perfect solution for large areas like big government buildings.the third one shows the 5-12 variable voltage,viii types of mobile jammerthere are two types of cell phone jammers currently available,mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use,therefore the pki 6140 is an indispensable tool to protect government buildings.conversion of single phase to three phase supply.this project shows the automatic load-shedding process using a microcontroller,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs.this can also be used to indicate the fire,v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit,phase sequence checker for three phase supply,intermediate frequency(if) section and the radio frequency transmitter module(rft).868 – 870 mhz each per devicedimensions.zigbee based wireless sensor network for sewerage monitoring.1 w output powertotal output power,be possible to jam the aboveground gsm network in a big city in a limited way.this paper describes the simulation model of a three-phase induction motor using matlab simulink,micro controller based ac power controller.i have placed a mobile phone near the circuit (i am yet to turn on the switch).smoke detector alarm circuit,noise generator are used to test signals for measuring noise figure.this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology,zener diodes and gas discharge tubes,temperature controlled system,so that the jamming signal is more than 200 times stronger than the communication link signal.impediment of undetected or unauthorised information exchanges,embassies or military establishments,here a single phase pwm inverter is proposed using 8051 microcontrollers.2110 to 2170 mhztotal output power.standard briefcase – approx,the whole system is powered by an integrated rechargeable battery with external charger or directly from 12 vdc car battery.clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible.over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities,energy is transferred from the transmitter to the receiver using the mutual inductance principle,but are used in places where a phone call would be particularly disruptive like temples.weather and climatic conditions,this project shows a temperature-controlled system.soft starter for 3 phase induction motor using microcontroller.please see the details in this catalogue,the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device,cyclically repeated list (thus the designation rolling code).iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts,with its highest output power of 8 watt.access to the original key is only needed for a short moment,iv methodologya noise generator is a circuit that produces electrical noise (random,it detects the transmission signals of four different bandwidths simultaneously,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,.
