In this paper, a design of a compact projector and hydrophone array is proposed. The FEM is utilized to simulate the performance of the projector and hydrophone, and several design parameters are optimized to achieve higher and flatter sensitivity/TVR response over the working frequency band. The measured performance of the manufactured compact array verifies the validity of the design.
An Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT)-based method is presented to estimate the gain-phase errors of both transmit and receive arrays in bistatic multiple-input–multiple-output (MIMO) radar. Unlike the recent ESPRIT-like methods, the directions of unknown targets and uncalibrated array steering vectors are first estimated with ESPRIT-based algorithm, and...
In this paper, a design of a high frequency PVDF hydrophone array is proposed. The FEM is utilized to simulate the performance of the hydrophone, and several design parameters are optimized to achieve higher and flatter sensitivity response over the working frequency band. The measured performance of the manufactured hydrophone array verifies the validity of the design.
Physical Unclonable Functions (PUFs) have emerged as an attractive primitive to address diverse hardware security issues in Integrated Circuits (ICs). A majority of existing PUFs rely on a dedicated circuit structure for generating chip-specific signatures, which often imposes concerns due to area/power overhead and extra design efforts. Furthermore, existing PUF-based signature generation cannot...
This paper introduces an interface platform to visualize location-specific media on lightweight displays that are placed and moved over a two dimensional map. The position of each display in the 2D space is dynamically sensed. The media data are transmitted to the detected display accordingly via a newly invented communication sheet underneath the map. Users can move the display on the sheet to magnify...
The increasing popularity of GPS device has boosted many Web applications where people can upload, browse and exchange their GPS tracks. In these applications, spatial or temporal search function could provide an effective way for users to retrieve specific GPS tracks they are interested in. However, existing spatial-temporal index for trajectory data has not exploited the characteristic of user behavior...
