Industrial laptop“Protecting our critical infrastructure

Smart factories, among the first to move forward with the Internet of Things (IoT) thanks to factory automation, will soon reap the benefits of another successful embedded SBC Intel IoT ecosystem collaboration. Intel Security and Honeywell embedded system Process Solutions are teaming up to bolster protection of critical industrial infrastructure. Intel Security’s McAfee technologies will enhance Honeywell’s Industrial Cyber Security Solutions offering, providing Honeywell customers with new choices to protect their control systems from malware and misuse.

Industrial laptop“Protecting our critical infrastructure and the emerging industrial computer from cyber threats is a national priority, and the partnership of two market leaders will go a long way toward that goal,” said Raj Samani, vice president and chief technology officer, Intel Security. “Technologies in the Industrial IoT space have a tremendous amount of potential, and we can’t let security concerns undermine that; instead, security has to enable the growth of industrial IoT, and that’s what our collaboration with Honeywell will do.”

Honeywell is a leader in the industrial computer space, and its Industrial Cyber Security Solutions group has a dedicated embedded system global team of experts that provide products, services and technologies to protect industrial automation and control systems against cyber threats. The collaboration combines Intel Security’s latest advances in cyber security technology with Honeywell’s unique industrial process domain knowledge to provide tailored security solutions for the industrial environment.

Power Management 101: Acrosser’s Slim On-Board Computer, AIV-HM76V1FL and Smart Power Settings

With seasoned engineers and industrial experience, Acrosser knows what matters when building anin-vehicle system: power management. This article will feature our latest ultra-slim in-vehicle computer: AIV-HM76V1FL, explaining the detailed BIOS setting in four different aspects. Let our talented built-in power management sub-system assist you customizing power setting.
Power on delay: The power on delay feature will protect the vehicle PC from sudden shutdown caused by sudden voltage surge or drop. This allows longer durability to the in-vehicle computer.
Software-off delay: This is the delay time once the ignition is OFF till power subsystem sends a turn off command to the motherboard. During the time, if ignition or remote switch is turned ON again, the power subsystem will automatically dismiss the OFF procedure, going back to operating condition.
Shutdown delay: This allows system to complete data-rewriting prior to each shut down. We suggest a higher value configuration if it takes longer time to shut down the program.
Hard-off delay: This is the delay time after power subsystem detects the OS has been shut down till the standby power is turned off. The unclosed OS will result in energy loss that drained the entire battery.
With proper power sub-system configuration, now engineers can build the vehicle that works for its project, and have the ability to reset those values anytime, anywhere.

2,500 jobs cut following Kraft Heinz merger

Kraft Heinz says it is cutting about 2,500 jobs as part of its plan to slash costs after the food companies combined.

Spokesman Michael Mullen says affected workers are in Canada and the U.S., where about 700 of the layoffs coming from Northfield, Ill., where Kraft had been headquartered. The company would not specify where other embedded SBC were taking place but saidd that all the jobs were salaried. It said none of the job cuts involved factory workers.

The Kraft Heinz Co. said it had a total of around 46,600 employees before the cuts. That included about 1,900 in Northfield. Hees had already overseen cost-cutting at Heinz since the ketchup maker was taken over in 2013 in a prior partnership between 3G and Berkshire. That means the cuts announced today mostly affect people on the Kraft side of the embedded system business.

Together, the two U.S. food giants own brands including Jell-O, Heinz baked beans and Velveeta that are facing embedded SBC sales challenges amid changing tastes. Their combination was nevertheless seen as attractive because of the opportunity to save hundreds of millions of dollars a year by combining functions like manufacturing and distribution. Executives say they expect to save $1.5 billion in annual costs by 2017.

“This new embedded system structure eliminates duplication to enable faster decision-making, increased accountability and accelerated growth,” said Mullen, adding that the savings will free up money to be invested back into the company's products.

Analog front ends for network appliance and gas sensors

Liquefied petroleum gas (LPG) is the most commonly used gas found in our homes. Leakage of LPG can be life threatening. Even in low concentrations it can be suffocating whereas if the concentration is high enough it can lead to a fire or cause a blast. Hence, it is extremely important to monitor the LPG level in our surroundings. Another type of gas that needs to be constantly monitored and kept within certain limits is CO2. High embedded system concentration levels can cause breathing problems and prolonged exposure can lead to death.
We can prevent gas exposure-based COMe Module accidents from happening by recording and maintaining gas levels in the immediate environment. Gas sensors can play a key role to this effect by raising an alarm when the level crosses prescribed safe limits. Advances in modern semiconductor technology have empowered us to design low-cost and low-power sensing solutions to make embedded system our homes, offices, and network appliance lives safer by keeping a check on the gas levels in our surroundings.
Every sensing system comprises a basic network appliance element that measures one or more electrical parameters like resistance or capacitance, and a circuitry that measures the changes in those parameters. Most of these sensors can operate on battery power so they can work uninterrupted for years on end. Hence, it becomes imperative that they consume low power for their operation. To pass the sensed information to the controller, analog front ends (AFE) are used. These allow the microcontroller to understand analog signals sent by sensors by converting them to a digital signal and then performing post processing on the received data.
Parameters measured by sensors: sensors measure changes in resistance and capacitance.
There are two common ways to measure a change in resistance: a potential divider COMe Module circuit and passing a known current. First, in a potential divider circuit, we connect a sensor whose resistance varies depending on some physical parameter like temperature, network appliance, etc. We compare the changing value of the sensor to a fixed value resistance. In such a circuit, the voltage of the connecting node (ADC) of the fixed resistance and the sensor depends on the resistance of the sensor and thereby on the physical parameter being measured.
