About CES

CES® Is the Global Stage for Innovation

CES® maintains that it is the ‘…most influential tech event in the world — the proving ground for breakthrough technologies and global innovators.’ The CES Las Vegas, Nevada destination is where the world's biggest brands do business and meet new partners, and the sharpest innovators hit the stage. Owned and produced by the Consumer Technology Association (CTA)®, CES features every aspect of the tech sector.

The first CES took place in New York City in June 1967. Since then, thousands of products are announced, displayed, and demonstrated at the yearly show. January, 2021, is the first CES presented entirely on-line. The registration requirements for the press, retailers, and exhibitors remained unchanged from the past in-person attendees. CES it is not open to the public. Last year it featured 4000+ exhibitors. For 2021, all 1,800+ exhibitors were on-line. (CES 2022 is planning to return to an in-person show.)

For this BAS-CES report, the guests have viewed multiple video presentations, and often YouTube cinemas to help you comprehend what is in-line for your home, refrigerator, video, or audio nirvana. It wasn’t easy compiling the menu for this presentation. Often, the manufacturer’s video would stop during presentation or the number of links to follow failed or exceeded our patience.

February 2021

The sound of a key sliding into a lock could be enough information to potentially create a copy of that key and open the lock – that's the conclusion of researchers who've been investigating "acoustics-based physical key inference".

It makes sense, if you think about it: the clicks and clacks of a key pushed into a pin tumbler lock actually reveal the mechanism within, if you can slow down, isolate, and analyse the sounds with enough accuracy.

Pulling off a trick like this would need a lot of work and equipment, and would probably end up being more hassle than learning how to pick the lock in the traditional way - but it's an intriguing and unusual security loophole to ponder.

The BAS is looking for an assistant editor. The B A S Speaker’s Editor seeks one or more individuals who will serve as an assistant editor, for no more than modest remuneration from the BAS.

Functions will include writing, editing, fact-checking, finding topics and articles for synopsis and reprint, obtaining reprint permission, and (to paraphrase the catch-all expression from job descriptions I worked under as a Federal civil servant) 'other duties as negotiated'.

You will get to work with a professional editor in the fields of audio and video. The work will allow you to acquire press credentials. Some technical knowledge is an asset but not requirement.

If interested, please email me to discuss.

In September 2009 the B A S held a microphone clinic, testing 37 different microphone models. The ambitious nature of the clinic effort, the extent of data collection, the number of individuals involved in microphone testing and in writing various sections of the report, and the complexity in determining how to construct the clinic report and make it available to members resulted it not being published until now. The dataset is extensive.

Representative samples were included in the abbreviated report in "The B A S Speaker"
(Fall 2015; v37n3)

When collecting and plotting "noisy" data it is often useful to have Microsoft Excel plot a Trend Line through it.  If that data is to be used for further work, it may be necessary to have an X-Y table of the Trend Line. That is not easy to get and this paper will show how to do it.
