This paper describes several noncontact methods of orienting objects in 3D space using Magnetic Levitation (MagLev). The methods use two permanent magnets arranged coaxially with like poles facing and a container containing a paramagnetic liquid in which the objects are suspended. Absent external forcing, objects levitating in the device adopt predictable static orientations; the orientation de...

We describe a rotating sample holder with two degrees of freedom for galvanomagnetic measurements at low temperatures which allows positioning within 0.5 degrees with a reproducibility of better than 0.5 degrees . The main advantages of our device over other constructions are simple and accurate device adjustment, simple and convenient handling, and simple and quick sample changing.

This paper presents a modified computer mouse, the Orienting Mouse, which delivers orientation as an additional dimension of input; when the mouse is moved on a flat surface it reports, in addition to the conventional x, y translation, angular rotation of the device in the x, y plane. The orienting mouse preserves important properties of the standard mouse; all measurements are relative and mov...

Failure in orienting towards occurring social stimuli represents one of the earliest and most basic social impairments in autism. Although, there are evidences for early signs of autism before three years of age, the available clinical tests for the diagnosis are not suitable for quantifying behavior alterations. There are no laboratory tests to con rm or disprove the diagnosis. My PhD work foc...

This paper deals with the design and execution of a solar tracker system dedicated to the PV conversion panels. The proposed single axis solar tracker device ensures the optimization of the conversion of solar energy into electricity by properly orienting the PV panel in accordance with the real position of the sun. The operation of the experimental model of the device is based on a DC motor in...

Prehension may be defined as “The act of taking hold, seizing or grasping, as with the hand” (Webster’s 3rd International Dictionary). Nonprehensile manipulation, then, can be defined as the manipulation of objects without grasping them. Manipulation without prehension is a natural way of handling objects for both humans and machines. The ability to manipulate objects which may not be graspable...
