A highly sensitive weak current detection circuit for implantable glucose monitoring is presented. The circuit consists of a current splitter, an integrator, a sampling/holding (S/H) circuit, and an 8-bit successive approximation register (SAR) analog-to-digital convertor (ADC). T-switches, source voltage shifting and correlated double sampling (CDS) technology are adopted to reduce the effects...

Recently, Microsoft introduced a game interface called Kinect for the Xbox 360 video game platform. This interface enables users to control and interact with the game console without the need to touch a controller. It largely increases the users’ degree of freedom to express their emotion. In this paper, we first describe the system we developed to use this interface for sound generation and co...

In this paper, interleave-division multiple access (IDMA) is used for overloaded multiple-input multiple-output (MIMO) coded orthogonal frequency division multiplexing (OFDM) systems. An iterative interference cancellation multiuser detection (IIC-MUD) method is proposed, which has almost the same complexity but can achieve almost optimal (MAP) performance, much better than that of elementary s...

Syntactic parsing is an important technique in the natural language processing, yet Latvian is still lacking an efficient general coverage syntax parser. This paper reports on the first experiments on statistical syntactic parsing for Latvian — a highly inflective Indo-European language with a relatively free word order. We have induced a statistical parser from a small, non-balanced Latvian Tr...

One of the fundamental problems with residue arithmetic is the difficulty associated with residue-to-binary conversion. In recently published papers, a hardware implementation of the Mixed-Radix system was proposed for the translation of residue coded outputs into binary number for a digital filter realization. These methods are presented as a block diagram or data flow chart and require integr...

The acoustic emission (AE) signal of wood damage is a kind of weak and highfrequency signal. Hardware circuit design and software programming are necessary for the acoustic emission data acquisition. In order to carry out further analysis, it needs to be preprocessed. The preprocessing hardware system consists of preamplifier, filtering circuit, main amplification circuit and AD converting circ...

This paper presents a novel digital miniaturization method for a prototype silicon micro-gyroscope (SMG) with the symmetrical and decoupled structure. The schematic blocks of the overall system consist of high precision analog front-end interface, high-speed 18-bit analog to digital convertor, a high-performance core Field Programmable Gate Array (FPGA) chip and other peripherals such as high-s...

Great effect of three way catalytic convertor (TWC) performance on oxygen sensor output voltage has made the sensor (located after catalyst) as the main signal in almost all today’s TWC monitoring algorithms. In this paper output voltage of nonlinear oxygen sensor is estimated using a nonlinear autoregressive with exogenous inputs (NARX) model. The estimation uses ECU calculated exhaust gas flo...

Our aim is to design a single axis solar tracker as well dual Intelligent microcontroller 12V Battery. The sun tracked by the and its position changed in such way that it maximizes power output. panel moved two geared DC motors so sun’s light can remain aligned with panel. operation of experimental model device based on motor which intelligently controlled dedicated drive until moves mini photo...
