Now that the Internet’s basic protocols are more than 30 years old, network scientists are increasingly turning their attention to ad hoc networks — communications networks set up, on the fly, by wireless devices — where unsolved problems still abound.
In some ways, granular material — such as a pile of sand — can behave much like a crystal, with its close-packed grains mimicking the precise, orderly arrangement of crystalline atoms. Now researchers at MIT have pushed that similarity to a new limit, creating two-dimensional arrays of micrograins that can funnel acoustic waves, much as specially designed crystals can control the passage of light or other waves.
Energy harvesting wireless technology is important for realizing interconnected M2M systems more reliably, conveniently, and economically while utilizing existing communication technologies. Machine-to-Machine communication enables equipment to interact with other equipment without human intervention, creating an intelligent network that automatically manages everyday tasks in production, logistics, monitoring, or smart buildings.
Researchers from North Carolina State University and the University of Texas have revealed more about graphene’s mechanical properties and demonstrated a technique to improve the stretchability of graphene – developments that should help engineers and designers come up with new technologies that make use of the material.

Worldwide shipments of tablet computers slowed down in the second quarter because Apple didn't release a new model of its trend-setting iPad, research firm IDC said Monday. Shipments totaled 45.1 million units in the April-June period, down nearly 10 percent from the first three months of the year.
everal airlines are experiencing flight delays nationwide because of a problem with a computer system they use for services such as reservations, check-ins, and online booking. Alaska Airlines spokeswoman Bobbie Egan says about 50 of its flights departing Monday night were delayed by an hour or less due to the outage.
This week on Engineering update, an impossible material made possible; a 3D printer gets sent to space; and BMW builds its first all-electric hatchback cakk the i3.
Tobin Richardson, Chairman and CEO of the ZigBee Alliance, will discuss the ZigBee Alliance and the progress it is making towards the Internet of Things, especially as it relates to the connected home. He will also touch base on the new Home Automation standard, as well as other "flavors" of ZigBee that go beyond the Home Automation Standard.
To offer an extra layer of protection for swimmers, Raleigh, NC-based SEAL Innovation has created the SEAL wearable swim monitor and drowning detection system that issues warnings and alarms to lifeguards and parents for swimmers in distress.
In this week’s episode of WDD’s HotSpot, brought to you by Memory Protection Devices, a smart home security device controlled from an iPhone; Telemakus USB range of USB controlled RF products; an iPhone biosensor that detects toxins; and a space laser communication system.
The Justice Department and 33 state attorneys general on Friday said they want to prevent Apple from entering into contracts with sellers of e-books, movies, music, and other digital content that are likely to raise prices. The demand comes out of an antitrust suit against Apple and five e-book publishers.
To deliver a great customer experience, operators are building next-gen networks capable of handling explosive volumes of traffic, even as subscribers continuously change devices, download applications, and find new ways to communicate.
Kirobo — derived from the Japanese words for "hope" and "robot" — was among five tons of supplies and machinery on a rocket launched Sunday from Tanegashima in southwestern Japan, the Japan Aerospace Exploration Agency, or JAXA, said. The childlike robot was designed to be a companion for astronaut Koichi Wakata and will communicate with another robot on Earth.
U.S. Trade Representative Michael Froman overruled a June decision by the U.S. International Trade Commission, which had banned imports of the iPhone 4 and some variations of the iPad 2. The commission ruled that the Chinese-made Apple devices violated a patent held by Samsung and couldn't be imported.
This week on Engineering Newswire, we're embedding sensors in your teeth to help track unhealthy acts; using the patch to help quit mosquitoes; designing temporary tattoo bio-sensors to warn extreme athletes when they are about to 'bonk'; and building the world's largest functioning brain ... model.
University of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses, and other molecules.
RFMW has announced design and sales support for Johanson Technology’s (JTI) chip antenna that can operate in both GPS and GLONASS bands simultaneously.
Specialized wireless transceivers and radiomodems from Ritron provide OEMs and Integrators with wireless connectivity and COTS convenience in a compact, cost-effective package.
Pharad has expanded the range of its peel and stick appliqué antenna product offerings to beyond 10 GHz with its latest addition, an Ultra-Wideband (UWB) antenna. Previously the peel and stick appliqué antenna family was offered for communication systems up to 6 GHz.
SkyProbes has announced its newest version of its long-range antenna for handheld VHF and UHF radios. The SSP58, with it’s highly flexible Titanium whip, gives up to 6 times the range over the rubber duck antenna supplied with commercial VHF handheld radios.
Sailing off Virginia Beach, Va., from July 13 to 18, the Office of Naval Research’s (ONR) Research Vessel (R/V) Knorr explored ocean and atmospheric weather variations that can change the angle that radar and radio waves bend, making it more difficult for ships to remain undetected and hindering their ability to communicate or locate adversaries.
Broadcom Corporation [NASDAQ: BRCM] has announced Broadcom's Near Field Communication (NFC) and Wi-Fi technology is powering Brother's new NFC printers. The integration of NFC into Brother's multi-function printers shows how the power of NFC is being adopted by a broader range of consumer electronic devices.
Researchers from the Georgia Tech Information Security Center (GTISC) have discovered two security weaknesses that permit installation of malware onto Apple mobile devices using seemingly innocuous applications and peripherals, uncovering significant security threats to the iOS platform.
Apple is facing accusations of shortchanging thousands of employees who haven't been getting paid while being forced to wait in line to show they aren't trying to steal an iPhone, iPad, or other merchandise from the company's bustling stores.
