Active joints for microrobot limbs [PDF]

open access: yes, 1992
The authors propose an electrostatic actuator for active joints. The active joint consists of two plates, one of which is a bilayer and bent by the bimorph effect. The plates are clamped to each other at one edge.

Active clamp dual-end convertor

open access: yesElectronics Letters, 1998
An active clamp dual-end convertor is proposed to achieve zero voltage switching for all switches with low voltage stress and eliminate the DC current component in the transformer. A 40 W prototype is built and the experimental results are obtained for verification.

Nanoscale-targeted patch-clamp recordings of functional presynaptic ion channels [PDF]

open access: yes, 2013
Important modulatory roles have been attributed to presynaptic NMDA receptors (NMDARs) located on cerebellar interneuron terminals. Evidence supporting a presynaptic location includes an increase in the frequency of mini events following the application ...

SMA Actuator with Active Clamp

open access: yesProcedia Engineering, 2012
AbstractThe paper deals with modeling and simulation of the Shape Memory Alloy (SMA) actuator for mechatronic systems. The thermal actuator made of Nickel–Titanium (NiTi) wire and new active clamp are heated by electric resistance heating and naturally air-cooled. The paper addresses FEM electro thermal simulation of NiTi actuator with special shape of

Active asynchronous secondary side voltage clamping [PDF]

open access: yesElectronics Letters, 2011
An asynchronous active voltage clamp for the secondary side of switching DC-DC converters is proposed. The control of the proposed clamping circuit is independent from the main converter, thus allowing use of a physically small inductor and offering increased control over the clamping operation.

Early postnatal caloric restriction protects adult male intrauterine growth-restricted offspring from obesity. [PDF]

open access: yes, 2012
Postnatal ad libitum caloric intake superimposed on intrauterine growth restriction (IUGR) is associated with adult-onset obesity, insulin resistance, and type 2 diabetes mellitus (T2DM).

Comparison of boost and LLC converter and active clamp isolated full-bridge boost converter for photovoltaic DC system

open access: yesThe Journal of Engineering, 2019
DC collection network offers an attractive alternative to AC network for photovoltaic, as it avoids the charging current issues and reduces the size and weight. Variable voltage gain DC/DC converters play an important role in DC collection network.

Whole-cell and Perforated Patch-clamp Recordings from Acutely-isolated Murine Sino-atrial Node Cells

open access: yesBio-Protocol, 2020
Cardiac pacemaker cells of the sino-atrial node are responsible for the initiation of the heart beat and express an array of ion channels. The patch-clamp technique is the gold standard method for investigating the function of ion channels expressed in ...
