Title: Suppressing spatial noise in multi-microphone devices
Inventor: JUHA TAPIO VILKAMO
IPC: G10L21/0208
Filed: 2020-06-24
Abstract: A spatial audio device having two microphones providing different directivity configurations determines a value (eg. direction or directionality in particular frequency bands) related to sound from a particular direction, and a value related to more omnidirectional spatial sound (eg. wind or traffic noise), and determines from these values a noise suppression parameter to be applied to the output audio. The signals may be combined using complex-valued beamforming weights to emphasize a particular “look direction”.

Abstract: Authentication processing is provided which includes generating an authentication parameter as a function of a time-dependent input using a predetermined transformation having an inverse transformation. Multiple authentication modes are supported, with a bit-length of the time-dependent input of one authentication mode being different from a bit-length of the time-dependent input of another authentication mode. Generating the authentication parameter is dependent, in part, on whether the time-dependent input is of the one authentication mode or the other authentication mode. A time-dependent password including a character string is generated from the authentication parameter using another predetermined transformation having another inverse transformation. The time-dependent password is forwarded within the authentication system for authentication by an authenticator.

Title: Bidirectional linear fast-response spiral winding type pneumatic artificial muscle based on braided tube
Inventor: XINGHAO HU
IPC: B25J9/10
Filed: 2021-11-26
Abstract: The present invention relates to the technical field of linear driving of soft robots, and in particular to, a bidirectional linear fast-response spiral winding type pneumatic artificial muscle based on a braided tube. According to the present invention, the output of force and displacement is achieved using the characteristic that the mechanical properties of a spiral braided tube change with internal expansion. Since the application direction of a load affects the expansion direction of the braided tube, when the direction of the load is different, the output directions of the force and displacement are also different, thereby achieving bidirectional driving. Compared with other pneumatic artificial muscles, the pneumatic artificial muscle in the present invention is smaller in air cavity volume and higher in inflation and deflation speed, and the pneumatic artificial muscle reduces the driving air pressure and increases the shrinkage rate while maintaining the high mass ratio and power ratio of conventional pneumatic artificial muscles , and has a high response speed.
