Easier Acoustics Modeling

Easier Acoustics Modeling Acoustics modeling just got easier thanks to a new acoustics module that's an add-on for Multiphysics™ 3.3, a finite-element-based multiphysics program. The package models acoustic wave propagation in air, fluids, and solids. Pertinent applications include speakers, microphones, hearing aids, sound barriers, and transducers for medical devices, nondestructive testing, and noise/vibration control. It's also recommended for modeling aeroacoustics, such as control of aircraft engine noise. A model library containing over a dozen working models is included. Antennas, waveguides, microwave, and optical components can be modeled with the RF Module. Request a complimentary CD on acoustics or RF simulation from Comsol Inc.

Merryweather Foam, Inc.
Foam for Sound Absorption

Foam for Sound Absorption Are you looking for a sound-absorption solution? Not sure what you need? You're not alone! Acoustical-absorption products are available in a range of mediums and designs that meet the specifications of engineers working in diverse industries. So, how do you determine the best choice for your project? It's not an easy decision to make, but it may well be a critical component of your bottom-line success. Find out more.

AE Techron, Inc.
Small Series Linear Amplifiers

Small Series Linear Amplifiers The LV 5507 is a versatile amplifier that can be operated as two independent channels or combined for maximum voltage in Bridge-mono mode. It is intended for use in low voltage, high impedance applications. It also features protection circuitry and devices guard against damage from improper loads. Find out more about AE Techron, Inc.

Plastic Faceplates Counter EMI

Plastic Faceplates Counter EMI Design versatility and cost-effectiveness promise to make electronic enclosures — injection molded of stainless-steel-filled thermoplastic — better options than expensive metals when electromagnetic interference (EMI) shielding is required. Offering 20 to 60 dB attenuations, faceplate panels made of conductive plastics provide corrosion resistance plus molded-in features. A single mold with changeable inserts produces varying cutout geometries for different circuit boards, says Design News.

"Solution" for Medical Device EMI

'Solution' for Medical Device EMI Wireless devices and biological signals like heartbeats can operate on the same frequencies, but if filters are used for electromagnetic interference (EMI), heartbeats may not be picked up. In the latest testing in saline solution, pacemakers, defibrillators, and other devices are exposed to magnetic, acoustic-magnetic, and radio frequencies. Output data helps assess how well alternate methods — e.g., refining firmware algorithms — handle EMI.

Models Avoid Connector Problems

In any electronic design, double checking everything is good, but it doesn't measure up to building a scale model to avoid potential snafus. Connectors are a particular concern says Daniel Harris of electronic design. In one instance, three meetings failed to catch a complex connector problem; in another, a two-pin connector had reversed pins. Of course, other faults may be preempted too.

Wireless USB vs Cables

Wireless USB vs Cables Cables to support USB peripheral devices are on the way out, reports Computerworld — thanks to wireless USB coming into its own for small offices, home offices, and consumers. Solving short-distance cabling complexities, wireless USB and Ultra-Wideband (UWB) are being backed by industry giants. So, within the next couple of years, wireless USB is expected to pop up in PCs, laptops, external hard disks, and other peripherals. Retrofits are also planned.

Acoustical Foam — Polyurethane

Acoustical Foam — Polyurethane Many applications require these products to be subjected to environments such as dirt, moisture, chemicals, and abrasion that could be hostile to an unprotected foam. IES-2000, Inc. has developed various surface treatments to protect the integrity of the foam from these elements.

Keystone Electronics Corp.
Audio Jacks and Plugs

Audio Jacks and Plugs Keystone Electronics Corp. carries surface mount stereo jacks that mate with 2.5 mm and 3.5 mm plugs. They are designed for reliable interface with audio equipment including computer speakers, headphones, sound cards, cell phones, etc. Models are available for mono and stereo applications and they have a low profile, surface mount design.

DSP Power-Saving Pluses

Choosing the right hardware and utilizing power-saving methods can minimize power consumption in both wired and wireless systems. For example, in mobile devices longer battery life or the use of a smaller battery is a benefit. Similarly in wired systems, a smaller power supply is an advantage. Optimizing power efficiency using both traditional and specific DSP (digital signal processing) techniques are addressed in this DSP DesignLine how-to article.

Chip Adds Digital Filtering

Chip Adds Digital Filtering Adding precision digital filtering to an application can readily be accomplished by installing a chip between an existing ADC (analog to digital converter) and the host controller. For controllers with embedded ADCs, it can function as a co-processor. Quickfilter's development kit, which includes the latest software, creates numerous filter designs without writing code. Accompanying hardware downloads the configuration into the chip to test filter performance.

Beware of Birds

Beware of Birds  When birds collide with aircraft the results can be disastrous. Now there's an audio telescope — actually, an array of 192 microphones — that hears and identifies oncoming birds, then warns off potential collisions. Adding more mikes, says this engadget report, is expected to improve the functional range from hundreds of meters to thousands.

These Microphone Chips are Cheaper

These Microphone Chips are Cheaper Less expensive than counterparts made by MEMS (MicroElectroMechanical System) processes, single-chip microphones produced by existing CMOS (Complementary Metal Oxide Semiconductor) processes also incorporate other functional circuits, reports Machine Design. With no noise pick-up like ECMs (Electret Condenser Microphones), and better sound, Akustica's new microphones are now in computers, with cell phone, video camera, and other applications apparent.

Star Micronics America
RDG-08B Electromotive Receiver

RDG-08B Electromotive Receiver The RDG-08B was developed mainly to be directed to the markets of mobile communication equipment and blue-tooth-compatible headsets that are "the trend" of small and thin devices. It was designed, by Star Micronics America, to meet space-saving requirements by making an 8 mm diameter round housing, and employing a highly reliable coil spring in the contact section to reduce the installed height down to about 2.4 mm.

'Air Guitar' Really Rocks

'Air Guitar' Really Rocks Australian scientists at the Commonwealth Scientific and Industrial Research Organisation have perfected an "air guitar" that actually works. In fact it's a T-shirt with sensors that wirelessly relay arm movements to a computer to create original music. Further applications like physiotherapy devices are under development for healthcare and sports markets, reports PhysOrg.com.

Security Guards

Screaming cell phones, proximity locks, and facial recognition software are the latest means of protecting your phone from theft. In the UK, the "screaming" deterrent service goes for about 120£ ($224) annually; Japanese phones with wireless proximity cards lock out beyond selectable distances. Interlopers within range can't access data either, thanks to a facial-recognition lock. GPS (Global Positioning System) can locate it, too.
