Coming off its big victory in its patent suit against Samsung in a Northern California court, Apple has filed an amended complaint with the same court in a separate case -- adding the Galaxy S3 and Galaxy Note to the list of Samsung devices it says infringe its intellectual property.

As reported by Apple Insider, the filing was made earlier today and involves a complaint first made in February that charged 17 Samsung devices with violating utility patents owned by Apple.

In relation to that complaint -- again, it's separate from the headline-grabbing case that began in April 2011 and wound up last Friday with an overwhelming win for Apple -- the iPhone and iPad maker sought a sales ban on Samsung's Galaxy Nexus smartphone. The San Jose, Calif., court where the complaint was filed granted the ban, but it has been temporarily lifted while it's on appeal before a court in Washington, D.C.

Apple also sought a ban on the Galaxy S3 back in June, but that effort was put on hold owing to a packed court schedule.

In the amended complaint filed today, Apple says "infringing Samsung products include the at least 21 new smartphones, media players, and tablets that Samsung has released beginning in August 2011 and continuing through August 2012" and it lists the Galaxy S3, the Galaxy S3 -- Verizon, and the Galaxy Note smartphones, as well as the Galaxy Note 10.1 tablet, among the other products.

Apple would no doubt like to put the kibosh on the Galaxy S3, which has enjoyed brisk sales and has, according to analysts, helped increase Samsung's lead over Apple in the two companies' smartphone sales competition. The Note seems to be doing OK too, if numbers released by Samsung are any indication.

Mahindra & Mahindra Ltd (M&M) is yet to meet the demands of its latest SUV—XUV 500—as it is always overbooked for several months. But its success has inspired the company quiet enough to launch another SUV in India. Quanto—the new compact SUV—will be launched in the second half of September. Though pictures of the car are not available, it will be the smallest SUV from Mahindra.

Quanto is indigenously designed and developed by M&M and is smartly packaged in sub-4 metre length on the proven Ingenio platform that it shares with the popular MUV, Xylo.

Mahindra coined the name Quanto with the aim of conveying a sense of space and power inherent in the product. Derived from the word ‘Quantum', the name has an association with the product's promise—more space, more power, more seats and superior performance. Quanto will have the toughest and most rugged DNA of Mahindra SUVs, thus offering a distinctive advantage over hatchbacks and sedans.

Quanto was innovated after taking into account a lot of customer feedback and research at its various stages of development. These insights have helped in fine-tuning the product to give a strong value proposition to customers in terms of design, performance and features.

Dr. Pawan Goenka, president of automotive & farm equipment sectors, Mahindra & Mahindra Ltd says, “Customer centric Innovation has always been at the heart of any product development at the Mahindra Group. With the Quanto, Mahindra is aiming to fill demand in the Indian automotive market for a versatile and compact SUV. We are confident that with its unique value proposition, the Quanto will carve out a segment for itself in the market.” Quanto is targeted at young urban travelers who are otherwise looking for premium diesel hatchbacks or entry-level diesel sedans. There is no official announcement about the pricing, but, it is expected to be anywhere between Rs 5.5 lakh to Rs 7 lakh.

Purdue University researchers have created a tiny mechanical device, an electrostatically actuated nanoresonator, that could help cell phone users avoid the nuisance of dropped calls and slow downloads.

It is designed to ease congestion over the airwaves to improve the performance of cell phones and other portable devices.

“There is not enough radio spectrum to account for everybody’s handheld portable device,” said Jeffrey Rhoads, an associate professor of mechanical engineering at Purdue University.

The overcrowding results in dropped calls, busy signals, degraded call quality and slower downloads. To counter the problem, industry is trying to build systems that operate with more sharply defined channels so that more of them can fit within the available bandwidth.

“To do that you need more precise filters for cell phones and other radio devices, systems that reject noise and allow signals only near a given frequency to pass,” said Saeed Mohammadi, an associate professor of electrical and computer engineering who is working with Rhoads, doctoral student Hossein Pajouhi and other researchers.

Nanoelectromechanical resonators contain a tiny beam of silicon that vibrates when voltage is applied. Researchers have shown that the new devices are produced with a nearly 100 percent yield, meaning nearly all of the devices created on silicon wafers were found to function properly.

“We are not inventing a new technology, we are making them using a process that’s amenable to large-scale fabrication, which overcomes one of the biggest obstacles to the widespread commercial use of these devices,” Rhoads said.

In addition to their use as future cell phone filters, such nanoresonators also could be used for advanced chemical and biological sensors in medical and homeland-defense applications and possibly as components in computers and electronics.

The devices are created using silicon-on-insulator, or SOI, fabrication - the same method used by industry to manufacture other electronic devices. The resonators can be readily integrated into electronic circuits and systems because SOI is compatible with complementary metal–oxide–semiconductor technology, or CMOS, another mainstay of electronics manufacturing used to manufacture computer chips.

The resonators are in a class of devices called nanoelectromechanical systems, or NEMS.

The new device is said to be “highly tunable,” which means it could enable researchers to overcome manufacturing inconsistencies that are common in nanoscale devices.
