Hi ui,
NB: Both documents are published applications, not granted patents, so the claims are subject to change.
This one is a vibration sensor:
"It is known to detect an abnormality of the rotary member in each of the home electronic appliances and the business machines by analyzing this operating noise by means of a predetermined method."

US2021404914A1 TIME SERIES SENSOR DATA PROCESSING DEVICE AND TIME SERIES SENSOR DATA PROCESSING METHODS
US20210404914 - TIME SERIES SENSOR DATA PROCESSING DEVICE AND TIME SERIES SENSOR DATA PROCESSING METHODS
Applicants
RENESAS ELECTRONICS CORPORATION
Claims1. A time series sensor data processing device, comprising:
a frame generating unit configured to generate a plurality of frames from time series sensor data acquired from a sensor,
each of the frames having a predetermined frame size,
the sensor being provided in an apparatus;
a time information adding unit configured to add a value indicating corresponding time information to each of the generated frames; and
a determining unit configured to determine presence or absence of an abnormality of the apparatus by using a neural network, the neural network learning a combination of each of the plurality of frames and the value indicating the corresponding time information and a combination of a data pattern of each frame stored in advance and predetermined timing.
As you can see, the learning is done in a separate CPU 201 on PC 200.
The priority date is mid-2020. The Agreement between BrainChip and renesas was announced December 2020. No doubt they will be able to improve on it implementing Akida with STDP.
