Each earpiece has a 5.7-mm dynamic speaker, a small electromagnetic transducer
, NFMI technology and a Bluetooth 4.2 chip with Digital Sound Processing that allows for dynamic sound tuning and sound without interruption.
Along a similar path, an electromagnetic transducer
connected with an energy harvestingenabled circuit is used to transform vibration energy into electric power and also to supply controlled force vibrations mitigation for TMD-equipped multilayer buildings structures in .
Inertial vibration control using a shunted electromagnetic transducer
, IEEE/ASME Transactions on Mechatronics 11: 84-92.
Up to now, this type of MEI uses either an electromagnetic transducer
or apiezoelectric diaphragm transducer as its vibrator.
An electromagnetic transducer
(similar with 4) measures the inner ring speed and we can read the ratio:
The CLT (Figure 2(b)) was based on a minimally invasive implantable electromagnetic transducer
design, described in detail by Stieger et al.
When our sensor SR4 with its electromagnetic transducer
is excited by ground motion vibration with angular rate rad/s then it generates the output voltage V = [U.sup.*]E = [U.sup.*] [B.sup.*] [phi] x [omega].
A phonographic tone arm, with the needle of the phonograph cartridge acting as an electromagnetic transducer
, was placed on the Sawbones adjacent to the outer shell and the impact signal transmitted to a laptop computer through a preamplifier--a technique previously used to measure impacts in the femur.
These load cells are said to be the first physically compact product to implement a superior electromagnetic transducer
technology for tension measurement in the 5-to-5,000-pound range on pillowblock-mounted rolls in web processing applications.
Recording CAEPs using a Baha as transducer could interfere with its unknown signal processing of the stimulus and artifacts in the EEG recording caused by the electromagnetic transducer
as described by Rahne et al.
