This paper introduces a single-chip, 200 200element sensor array implemented in a standard two-metal digital CMOS technology. The sensor is able to grab the fingerprint pattern without any use of optical and mechanical adaptors. Using this integrated sensor, the fingerprint is captured at a rate of 10 F/s by pressing the finger skin onto the chip surface. The fingerprint pattern is sampled by c...

Recently, dry power transformer (Dryformer) that performs one step transformation from transmission to distribution voltage levels, has been introduced [1]. The Dryformer (dry power transformer) combines the features of power transformer with that of station distribution transformer, by utilising XLPE insulated round conductor cable for winding construction. The parameters of the cable winding ...

In this paper we present an electronic circuit for position or capacitance estimation of MEMS electrostatic actuators based on a switched capacitor technique. The circuit uses a capacitive divider configuration composed by a fixed capacitor and the variable capacitance of the electrostatic actuator for generating a signal that is a function of the input voltage and capacitive ratio. The propose...

Capacitive touch sensing is increasingly used in musical controllers, particularly those based on multi-touch screen interfaces. However, in contrast to the venerable piano-style keyboard, touch screen controllers lack the tactile feedback many performers find crucial. This paper presents an augmentation system for acoustic and electronic keyboards in which multi-touch capacitive sensors are ad...

Stabilization of the ‘‘resistive shell mode’’ is vital to the success of the ‘‘advanced tokamak’’ concept. The most promising reactor relevant approach is to apply external feedback using, for instance, the previously proposed ‘‘fake rotating shell’’ scheme @R. Fitzpatrick and T. H. Jensen, Phys. Plasmas 3, 2641 ~1996!#. This scheme, like other simple feedback schemes, only works if the feedbac...

Aswith all amplifier circuits, certain operating conditions can cause instability of a potentiostatic circuit which maymanifest as overshoot, poorly-damped ringing, or in extreme cases full-scale oscillations at the CE output. Instability occurs when the phase shift in the circuit’s feedback loop (the path between the output and the inverting input of U1 in Fig. 2 in the main text) is sufficien...
