In this paper, a novel electrostatic switch is reported that exhibits an ON/OFF capacitance ratio of 72, an ON capacitance value of 90 pF, and a pull-in voltage of less than 5 V within an area of 750 × 750 μm. These characteristics are achieved by utilizing a slit-shape middle metal layer in-between the top and bottom metal plates. This design makes the capacitance ratio and the ON state capaci...

Background & Importance: Acute epidural hematoma is a very rare complication of ventriculoperitoneal shunt insertion. The insertion of a ventriculoperitoneal shunt can cause sudden decompression of the brain, subsequent to which epidural hematoma occurs due to CSF drainage. To our knowledge, there are only a few cases of acute epidural hematoma in the literature which required acute e...

An experimental setup for the characterization of electromagnetic induced heat on MEMS devices undertaking high RF power regime (> 5W) is here proposed. The technique is based on infrared (IR) imaging of on-probe DUT, while it is in working conditions. The measured temperature distributions, for different working state of a RF-MEMS switch, are given. The results show that for a first considered...

In this work, activated carbon (AC) derived from biomass wastes was implemented as electrode materials in supercapacitor application. This study has adopted rubber seed shell (RSS) wastes to derive AC via pyrolysis process. Meanwhile, reduced graphene oxide (rGO) was used as an additive material in order to study the effect of the rGO in capacitive behavior. The synthesized rGO was successfully...

This paper reports on an electrostatic Vibration Energy Harvester (e-VEH) system, for which the energy conversion process is initiated with a low bias voltage and is compatible with wideband stochastic external vibrations. The system employs the auto-synchronous conditioning circuit topology with the use of a novel dedicated integrated low-power highvoltage switch that is needed to connect the ...

radionuclide shuntography is a safe and simple method to determine shunt patency and analyze changes in csf (cerebro-spinal-fluid) flow. we present a case of complicated csf shunt, in which radioisotopic scan correctly identified disconnection of the shunt tubing system localizing the site of extravasation accurately. the findings were confirmed by surgery performed for correction of the shunt ...

conclusions bladder perforation and stones are rare examples of complications in v-p surgical procedures. controlling the effective length of the terminal v-p shunt and modifying it appropriately can effectively reduce these complications. case presentation we report on a 38-year-old male who had hydrocephalus and v-p shunt for 12 years. two years ago, he found himself with recurrent urinary tr...

Introduction With the guide field parameters of the SLAC storage ring (SPEAR), a 2.5 GeV electron will radiate 272 keV of energy each revolution. A peak RF voltage of 350 kV will restore this radiated energy with an adequate lifetime for quantum fluctuations. This energy will be supplied from an RF system operating at 51.22 MHz, which is the 40th harmonic of the rotation frequency. For initial ...
