Digital TV Rollout

Has the United States got it wrong with digital terrestrial TV?

Few would dispute that Hughes, RCA, and Thomson got it right when they launched the U.S. digital satellite pay-television service DirecTV six years ago. It gave viewers a long-overdue and welcome alternative to cable TV. But today new digital terrestrial network services in the United States are creating little interest. Receivers are expensive and sales slow. For example, a leading consumer electronics store in New York City offered, at press time, Panasonic HDTV-compatible sets for prices from US $1500 to $2800. Although there are now more than 170 TV stations in the country that use the digital TV standard set up by the Advanced Television Systems Committee (ATSC), Washington, D.C., only around 625 000 ATSC sets have been sold.

Chip Fabs Go Green

A new consortium of fabs and suppliers wants the semiconductor industry to cut its carbon footprint

At this week's COP27 climate conference in Egypt, attendees will have a new group to contend with: an alliance of more than 60 companies involved in the electronics supply chain. Called the Semiconductor Climate Consortium, it formed last week in collaboration with SEMI, the industry association for the electronics manufacturing and design supply chain. The aim is to reduce greenhouse gas emissions "throughout the electronics value chain," according to SEMI. The founding members have all affirmed support for the Paris Agreement, which is aimed at limiting global warming to 1.5 celsius.

Founding members include some of the biggest owners of semiconductor fabs, including GlobalFoundries, Intel, Micron, Samsung Electronics , SK Hynix, and TSMC. But it also includes some fabless companies such as AMD, Google, and Microsoft. Suppliers of equipment, chemicals, and packaging technology are also well represented among the founders.

Robotic Falcon Keeps Birds Away From Airports

But is its large silhouette, not its resemblance to a noted raptor, the real scare factor?

Collisions with birds are a serious problem for commercial aircraft, costing the industry billions of dollars and killing thousands of animals every year. New research shows that a robotic imitation of a peregrine falcon could be an effective way to keep them out of flight paths.

Worldwide, so-called “birdstrikes” are estimated to cost the civil aviation industry almost $1.4 billion annually. Devoting significant resources to dealing with the challenge, she says, for many means hiring full-time bird control experts. Nearby habitats are often deliberately made unattractive to birds, but airports also rely on a variety of deterrents designed to scare them away such as loud pyrotechnics or speakers that play distress calls from common species.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Rohde & Schwarz

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
