A bidirectional fiber-IVLLC and fiber-wireless convergence system based on two orthogonally polarized optical sidebands for hybrid CATV/MMW/BB signal transmission is proposed and demonstrated. Two orthogonally polarized optical sidebands are transmitted over a 40-km SMF transport to effectively reduce the fiber dispersion and the distortion. The approach presented in this work signifies the advancements...
The paper presents a scheme to generate a focused THz source using a disc-like antenna array for THz CMOS-based transceiver application. The disk-like antenna array is fabricated by pressing a steel ball onto a flexible flat antenna array placed on a hollow silicon mold to form a hemispherical shell disk. Simulation results show that the receiving power from the center of the disc-like patch antenna...
The paper presents a scheme to improve the performance of on-chip spiral inductors using metal-oxide based anodic alumina oxide (AAO) nanocomposites such as Fe3O4-AAO nanocomposite used here for demonstration. The fundamental enhancement principle is to eliminate eddy current loss but keep a high ferromagnetic resonance frequency in terms of the additive of nonconductive magnetic nanorod structures...
Wearable Augmented Reality (W-AR) is based on getting a computer as intimate as possible with the wearers' bodies and senses. We need to understand the cognitive and perceptual mechanisms leveraged by this technology and use them for designing AR applications. In this study we explored the potential benefit of W-AR to guide a procedural task of assembling a LEGO™ compared to traditional paper instructions...
This study utilizes 355 nm ultraviolet (UV) laser' micro electroforming process with supercritical fluid to package 4G solidly mounted resonator (SMR) wafer. The diameter of drilling hole was 100–150 μm with the wafer thickness of 550 μm' and the component was packaged by the embedded circuit and through silicon via (TSV) technology. Experiment results show the aspect ratio was around 5 and the sidewall...
We investigate athermal characteristics of silicon waveguides clad with TiO2. The measured ring resonance wavelengths near 1.3 μm over 20–50°C exhibit second-order thermo-optical effects and spectral dependency, implying second-order effects from TiO2 and Si combination.
Inkjet printing has been one of fascinating techniques for microfabrication owing to the characteristics of low manufacturing cost, low processing temperature, low material usage,…etc. [1, 2]. In this work, a Lift-off Printing (LoP) process combining conventional photolithography and inkjet printing processes is introduced to realize printed size-scalable silver microstructures with the line width...
Experimental demonstrations of ring resonators with TiO2 cores are presented and measured with −2.9pm/K resonance shift. Their thermo-stress-optic behavior was found to be important to their function; therefore an inclusive model is presented and simulated numerically.
The paper discusses practical issues involved in applying scan bandwidth management to large industrial system-on-chip (SoC) designs deploying embedded test data compression. These designs pose significant challenges to the channel bandwidth management methodology itself, flow, and tools. The paper introduces several test logic architectures that facilitate preemptive test scheduling for SoC circuits...
The paper presents both anti-inference packaging and effective calibration schemes for accurate current detection in household appliance using flexible current tags. The sensor with NiFe C-clamp stripes can effectively prevent electromagnetic interference (EMI) effect and reduce the measurement error down to less than 2%, while the external current source is placed 1cm away from the power cord to...

An adaptive maneuvering target tracking algorithm for Doppler radar is proposed, where both the sampling interval and transmitting waveform can be adjusted according to the predicted error covariance output from IMM filter adaptively. Compared with tracking algorithm of fixed sampling interval or transmitting waveform, the adaptive tracking algorithm can save the consumed system resource effectively...
In this paper, we present a 64nm pitch integration and materials strategy to enable aggressive groundrules and extendibility for multi-node insertions. Exploitation of brightfield entitlements at trench and via lithography enables tight via and bi-directional trench pitch. Setting the same mask metal spacing equal to CPP maximized density scaling and speed of standard cell automation by avoiding cell...
No currently available clinical technique is capable of visualizing and quantifying the structure and function of the middle ear. Various pathologies directly impede the conduction of sound-induced vibrations through the human middle ear, and thereby produce a ‘conductive’ hearing loss. Direct clinical assessment of sound conduction by middle ear structures has been limited to measurements of the...
A light-emitting diode (LED) light bar for display monitor may be composed from thousands feasible LED combinations due to supplies of LED bins featured by voltage, illumination, and chromaticity. To control inventory levels by bins, this work proposes a novel multi-level linear programming based system capable of maximizing LEDs allocations of light bar work orders. Filtering from feasible LED combinations...

In a multi-robot system, robots are typically required to collaborate over a communication network to achieve objectives cooperatively. Due to the limited communication and sensing capabilities on each robot, the cooperative objective must be accomplished while ensuring that specified robots stay within each other's sensing and communication ranges and that the overall network remains connected. In...
