Randomes (brand emblems) or bumpers are cased inside a protective cover with automotive radars mounted over it. The radars are invisibly integrated behind bumpers in order to attain signal transparency. The Lohnert Elektronik, a leading specialist in custom test benches were looking for a reliable solution for losses in radars. High losses reduce the maximum range within which a radar can detect the obstacle. 

Rhode & Schwarz quickly came up with an intellect solution to detect obstacles in order to prevent such marginal losses. The R&S QAR (Quality Automotive Randome) tester is an ideal R&D tool for identifying, measuring and analyzing the capabilities of the radar with scientific image processing. As Lohrent Elektronik integrates this technology into their legacy tester device, thus covering the entire test cycle with less than ten seconds. The radar signals operate usually in the range of 77 and 79 GHz bands (E band). The tester binds all the distortions by reproducibly showing millimeter wave images based on distributed planar arrays. It gives a reliable evaluation of randome performances by spatial reflection measurements, revealing even the smallest inhomogeneity of the material.

This reliable test bench is driven by the Lohrent instant scripting run time software (LisRT V3) along with Siemens SPC controller. They are available for automotive randomes up to 200mm in diameter. The system identifies their hallmark by a data matrix code (DMC) for all the machines undergoing the transmission and reflection reference measurements. The measurement results are highly appreciable as they can be delivered to other systems, supporting manual and automatic test systems.

Mobile Phones are no longer a device that can address phone calls. It has become a personal gadget that can play music and vedios , surfing , taking snaps and connecting people through social media platform. Hence to peform all these tasks swiftly and with great ease , need for powerful processors are always in demand. A mobile processor is just like a brain of our mobile phone. The entire architecture of our personal device depends on processor.  Highly influenced by the personal computer processors , mobile processors are embedded in a small chipset with multiple cores ( Dual , Quad , Hexa and Octa ). The core handles the tasks which are assigned by the user while using their smartphone.  The processor must posses a good clock speed , which will aid in executing many instructions in a second.  Hence phones with multi-processor core and higher clock speed will be comparetively expensive but will gurantee high speed and performance. Higher core can also lead to...

Cloud computing involves delivering different types of services over the Internet. From software and analytics to secure and safe data storage and networking resources, everything can be delivered via the cloud. By using cloud storage, we don’t have to store the information on our own hard drive. Instead, we can access it from any location and download it onto any device of our choice, including laptops , tablets and smartphones. There are different types of cloud computing services available to suit different needs. While some cater to individual users who want to store photos, documents, and videos, others are destined for companies that need extensive platforms to develop IT applications. Cloud Computing Architecture Image Courtesy : Google Images Cloud computing is device independent because cloud computing resources can be accessed not just from any computer on the Internet, but also any type of computer. Provided that it has an Internet connection and a we...

Quantum Computing

Quantum mechanics emerged as a branch of physics in the early 1900s to explain nature on the scale of atoms and led to visionary inventions such as transistors, lasers, and magnetic resonance imaging. Hence after so much breakthrough discoveries quantum mechanics was merged with information theory leading to Quantum Computing. Superposition is the counter intuitive ability of a quantum object, like an electron, to simultaneously exist in multiple “states.” With an electron, one of these states may be the lowest energy level in an atom while another may be the first excited level. If an electron is prepared in a superposition of these two states it has some probability of being in the lower state and some probability of being in the upper. A measurement will destroy this superposition, and only then can it be said that it is in the lower or upper state. Components Associated With Quantum Computing                       ...
