MILKey: multi illuminated indicator for KEYpad

We propose a novel multi-dimensional zero-phase infinite impulse response (IIR) notch filter having multiple independently-tunable notches. The proposed notch filter employs a cascade structure with M N-dimensional (N-D) zero-phase IIR filters to ...

This paper presents Keypad, an auditing file system for theft-prone devices, such as laptops and USB sticks. Keypad provides two important properties. First, Keypad supports fine-grained file auditing: a user can obtain explicit evidence that no files ...

This paper proposes an adaptive notch filter that automatically adjusts the notch frequency and notch gain, where they are the null frequency and the depth of the null, respectively. The proposed notch filter consists of an inverse notch filter and a ...
