Atmospheric pressure plasma jet(APPJ) typically cover only a few millimeters, which limit its processing area. Grouping many individual jets together to form a jet array is a good solution for meeting large surface treatment applications. In this paper, a honeycomb two-dimensional plasma jet array consisting of 7 jet units with needle-ring electrode-plate electrode structure is generated in argon...
Firstly an embedded 55-nm Flash design based on split-gate Flash bitcell is proposed by 32KX64 IP. It demonstrates competitive features for production by wide voltage supply range (VDD=0.86~1.32V, and VD25=1.6~3.6V), low-power read feature (96uA/MHz, 64 bits), fast wake-up time from power off (<; 2us), and fast operation read speed up to 75MHz (VDD=1.08V).
Spatial multizone soundfield reproduction over an extended region of open space is a complex and challenging problem in acoustic signal processing. In this paper, we provide a framework to recreate 2-D spatial multizone soundfields using a single array of loudspeakers which encompasses all spatial regions of interest. The reproduction is based on the derivation of an equivalent global soundfield consisting...
Recently, a new concept of rotation scanning synthetic aperture interferometric radiometer (RS-SAIR) has been receiving more and more attentions for its advantage of much simpler configuration with looser requirements of antenna elements. In this article, we investigate the imaging theory of RS-SAIR, and introduce the pseudo-polar FFT algorithm to deal with the polar u-v samples. It only involves...
Applying synthetic aperture interferometric radiometer (SAIR) in near field imaging has been receiving great interest in the recent years. Because the traditional far-field Fourier imaging theory is not valid in near-field condition, developing the proper near-field imaging techniques is the major desirable objective of near field SAIR applications. This work is devoted to establish an effective near...
Electrical stimulation of the optic nerve with penetrating electrode array for visual recovery had been proposed by C-Sight group. This paper presents the latest progress of various component parts of visual prosthesis, including design and testing of neural stimulator, fabrication of multi-channel flexible microelectrode array. According to the experiment data, the linearity between practical stimulator...
A novel scalable and stackable nonvolatile memory technology suitable for building fast and dense memory devices is discussed. The memory cell is built by layering a storage element and a selector. The storage element is a Phase Change Memory (PCM) cell and the selector is an Ovonic Threshold Switch (OTS). The vertically integrated memory cell of one PCM and one OTS (PCMS) is embedded in a true cross...
We present the design for OpenPET, an electronics readout system designed for prototype radiotracer imaging instruments. The critical requirements are that it have sufficient performance, channel count, channel density, and power consumption to service a complete camera, and yet be simple, flexible, and customizable enough to be used with almost any detector or camera design. A unique feature of this...
This paper reports the design, fabrication and simulation of a novel array of micromachined electrodes with different lengths for use in auditory nerve prostheses. A 10times10 array is created in a 1 mm 2 on silicon with bulk micromachining technology. The electrode lengths vary from 200 mum to 400 mum. This design could provide access to most fascicles within the auditory nerve and thus allow stimulation...
