The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.
The original Alexa wasn't built for natural conversations involving back-and-forth chatter. Instead, it replies to simple questions or commands by pulling from an evolving set of pre-determined ...
In electrical circuits, ringing is an oscillation of a voltage or current.Ringing can be undesirable because it causes extra current to flow, thereby wasting energy and causing extra heating of the components; it can cause unwanted electromagnetic radiation to be emitted [citation needed]; it can increase settling time for the desired final state; and it may cause unwanted triggering of ...
Ringing is closely related to overshoot and undershoot, which is when the output takes on values higher than the maximum (respectively, lower than the minimum) input value: one can have one without the other, but in important cases, such as a low-pass filter, one first has overshoot, then the response bounces back below the steady-state level ...
Woman experiencing ear ringing. ... making it less noticeable," Lewis says. "Sound therapies are also helpful for tinnitus sufferers, which can be in the form of white noise, a fan, nature sounds ...
Amazon announced new AI capabilities for its Alexa products last week, based on a model it’s calling AlexaLLM (LLM refers to the “large language model”). The technology will make Alexa ...
Amazon Alexa, or, Alexa, [2] is a virtual assistant technology largely based on a Polish speech synthesizer named Ivona, bought by Amazon in 2013. [3] [4] It was first used in the Amazon Echo smart speaker and the Amazon Echo Dot, Echo Studio and Amazon Tap speakers developed by Amazon Lab126.
A second generation of the Echo Show was unveiled at an Alexa-themed product event by Amazon on September 20, 2018, for release the following month. [75] The new device has a 10-inch touchscreen, improved speakers, and mesh casing. [76] Amazon has released three additional sizes of the Echo Show making them available in 5-, 8-, and 15-inch ...
