    Abstract: Voice activity detection (VAD) is an enabling technology for a variety of speech based applications. Herein disclosed is a robust VAD algorithm that is also language independent. Rather than classifying short segments of the audio as either “speech” or “silence”, the VAD as disclosed herein employees a soft-decision mechanism. The VAD outputs a speech-presence probability, which is based on a variety of characteristics.

  • Publication number: 20200357430
    Abstract: An apparatus, according to one approach, includes two arrays of data transducers on a module, the two arrays being aligned along a common axis extending between distal ends of the module. Outer servo readers are positioned toward outer ends of the two arrays. An inner servo reader is positioned between the two arrays. The servo readers are positioned to each reside above a unique servo track on a magnetic recording tape. A method according to one approach includes passing a magnetic recording tape having a plurality of data bands over a module as described above. Data is simultaneously transduced on the two data bands using the data transducers. Advantageously, the number of simultaneously-usable channels on the module is dramatically increased, thereby also dramatically increasing the data rate per unit of tape speed, while backward compatibility may be preserved.

  • Publication number: 20200357431
    Abstract: A junction shield (JS) structure and method of forming the same are disclosed for providing longitudinal bias to a free layer (FL) having a width (FLW) and magnetization in a cross-track direction between sidewalls in a sensor. The sensor is formed between bottom and top shields and has sidewalls extending from a front side at an air bearing surface (ABS) to a backside at a stripe height (SH) from the ABS. The JS structure has a lower layer (JS1) with magnetization parallel to that of the FL, and a tapered top surface such that JS1 has decreasing thickness with increasing height from the ABS. As aspect ratio or AR (SH/FLW) increases above 1, longitudinal bias increases proportionally to slow an increase in asymmetry as AR increases, and without decreasing amplitude for a reader with low AR. The JS1 layer may be antiferromagnetically coupled to an upper JS layer for stabilization.

The pass gate couples the bit line to the power node when the first signal has the reference voltage level and decouples the bit line from the power node when the first signal has the first power voltage level. The driver receives a second signal based on a control signal, couples the bit line to the reference node when the second signal has a second power voltage level below the first power voltage level, and decouples the bit line from the reference node when the second signal has the reference voltage level. An input circuit generates the first signal independent of the control signal.
