Body area network for wireless patient monitoring
TLDR
A BAN system is presented, which allows the connectivity of a wide range of heterogeneous body sensors to a portable hub device that is connectable to external networks (IEEE 802.11, GPRS) and can substantially improve the performance of different services, especially those that are health related.

Hardware-based support vector machine for phoneme classification
TLDR
This paper presents the design of a digital hardware implementation based on Support Vector Machines (SVMs), for the task of multi-speaker phoneme recognition, and a priority scheme was also included in the architecture, in order to forecast the three most likely phonemes.

Analysis of the Spur Characteristics of Edge-Combining DLL-Based Frequency Multipliers
TLDR
A complete analysis of the spur characteristics of edge-combining delay-locked loop (DLL)-based frequency multipliers is presented and a way to reduce the mismatch between the delay cells in the delay line is discussed via an analytic model and verified by the implementation of a delay cell in a 65-nm CMOS process.

Analog CMOS Chipset for a 2-D Sound Localization System
TLDR
This paper presents the measurement results obtained from three cue extraction chips implemented using standard 0.8 μm double-poly double-metal CMOS technology and shows that 2-D localization accuracy of 5° is possible using hardware-extracted localization cues.
