An Ultrasonic Suction Pump with No Physically Moving Parts
A new ultrasonic suction pump is described in this paper. The pump uses suction force of the rigid cylinder tube vibrating at an ultrasonic frequency and has no physically moving parts. The pump is consists of a longitudinal bolt-clamped Langevin transducer (BLT) combined with a stepped horn working at its resonance frequency of 24 kHz. A glass tube of the half-wavelength-resonance length is gl...
متن کاملCatoms: Moving Robots Without Moving Parts
We demonstrate modular robot prototypes developed as part of the Claytronics Project (Goldstein et al. 2005). Among the novel features of these robots (“catoms”) is their ability to reconfigure (move) relative to one another without moving parts. The absence of moving parts is central to one key aim of our work, namely, plausible manufacturability at smaller and smaller physical scales using hi...
متن کاملThe Brain ’ S Moving Parts
Ju ly 20 0 8 So natural is our capacity for rhythm that most of us take it for granted: when we hear music, we tap our feet to the beat or rock and sway, often unaware that we are even moving. But this instinct is, for all intents and purposes, an evolutionary novelty among humans. Nothing comparable occurs in other mammals nor probably elsewhere in the animal kingdom. Our talent for unconsciou...
متن کاملDyson’s lemma with moving parts
In its original form [D], Dyson’s Lemma bounds the order of vanishing of a polynomial in two variables at a finite set of points and was used in studying rational approximations to a fixed algebraic irrational number. Bombieri [B] revived interest in Dyson’s Lemma and subsequently Esnault and Viehweg [EV] and Vojta [V1] vastly extended the scope of the result, to polynomials in several variable...
متن کاملAxial coding in full-field microscopy using three-dimensional structured illumination implemented with no moving parts.
We report a simple optical setup to produce both axial and lateral structured illumination through a single objective lens. With a minimum of six full-field images obtained without moving either the sample or the microscope objective, 100 nm diameter fluorescent beads can be localized axially with an accuracy of 50 nm in a 1.76-microm-thick layer. We show that this axial localization improvemen...
