🔊 Wearable ultrasound sensor delivers noninvasive treatment with adjustable, body-conforming design
https://medicalxpress.com/news/2025-11-wearable-ultrasound-sensor-noninvasive-treatment.html
Conventional wearable ultrasound sensors have been limited by low power output and poor structural stability, making them unsuitable for high-resolution imaging or therapeutic applications.

Today's adventure: seeking #sailing electronics.
One can #sail most places with a few #charts and tools, a #DepthSounder, and hopefully a pair of binoculars. Modern sounders are a marvel of technology - a standard #transducer reports through-water speed, water temp, angle of heel… and depth.
A #GPS device is now considered standard, though most people rely on their mobile phone. A #ChartPlotter is a better tool, and can display sensor information too.
But not exactly free…
Researchers reveal new #cellular #mechanical #transducer.

Este es el mejor!
People often “blame” Shannon’s theory of #communication for completely ignoring #meaning, maybe also because Shannon himself stated that “the semantic aspects of communication are irrelevant to the engineering aspects“😀
However, if one recognizes that the #information content as defined by the #entropy is the measure of #uncertainty in a receiver about the sender’s #state when producing the message, can it perhaps be interpreted that the receiver is trying to #understand what the sender was #meaning to send?
The information the sender encodes in the message is never the same as that the receiver decodes from it on the other side of the channel.
Below is Shannon’s description of the standard #transducer used for encoding and decoding the information in messages. The block diagrams are my rendering of the description (F is a “#memory” function):
The use of the terms #transformer and #transducer seems somehow different in #AI than in other #engineering disciplines.
In engineering a “transformation” means altering the #form of the same #substance and “transduction” is used when the form is “produced” in another (different) substance.
For example, a #transformer will change (reduce or increase) the voltage “pressure” of an AC current source while a #transducer such as a microphone will change an acoustic pressure (wave) to an electric signal.

In recent years, Transducers have become the dominant ASR model architecture, surpassing CTC and LAS model architectures. In this article, we will examine the Transducer architecture more closely, and compare it to the more common CTC model architecture.
