This lab will begin by studying motion in 1 dimension, under constant acceleration, by launching a projectile directly upward and measuring the maximum height reached. This lab will verify that the maximum height reached is consistent with the kinematic...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Colloquially, the terms learning and memory encompass a broad range of behaviors and mental systems, everything from learning to tie a shoe to mastering calculus (and a lot in between). Experimental psychologists have divided up learning mechanisms into groups that seem to have different properties, and that seem to rely on different brain systems. A major division is between declarative and non-declarative memory, roughly, the...

We developed a real-time mirror robot system for functional recovery of hemiplegic arms using automatic control technology, conducted a clinical study on healthy subjects, and determined tasks through feedback from rehabilitation doctors. This simple mirror robot can be applied effectively to occupational therapy in stroke patients with a hemiplegic arm.

When an object moves with constant acceleration, the velocity of the object changes at a constant rate throughout the motion. The kinematic equations of motions are derived for such cases where the acceleration of the object is constant. The first kinematic equation gives an insight into the relationship between velocity, acceleration, and time. We can see, for example: Final velocity depends on how large the acceleration is and how long it lasts If the acceleration is zero, then the final...
FAQs
The three-point arrangement converts actuator motion into controlled angular changes rather than allowing arbitrary movement. Two adjustment screws or actuators independently set tilt about perpendicular axes, while the fixed reference point supplies a stable constraint. This separation lets an operator correct beam direction in two angular dimensions and return to a previously established orientation with repeatable control.
The fixed reference point prevents the reflective surface from shifting without constraint while the two adjustable contacts change its orientation. That mechanical relationship makes corrections more predictable than an arrangement in which several points move freely. In practice, stable referencing supports consistent beam positioning and helps preserve alignment when an optical path must be adjusted or revisited.
Because the controls act around perpendicular axes, alignment can be corrected separately in two angular directions. An operator can therefore address one directional component of beam placement without treating the mirror as a completely unconstrained part. This controlled adjustment is important when the goal is not merely to reflect light, but to position and focus it consistently within an optical instrument.
Mechanical constraint links the reflective surface to defined contact points, limiting unintended motion during adjustment. That limitation supports repeatable orientation changes, which in turn affects where a beam travels and how it is focused. For bioengineering measurements, reducing uncontrolled mirror movement helps maintain consistency across fluorescence excitation, imaging, and optical trapping setups.
Begin with the mirror held by its defined mounting contacts and use the two adjustment screws or actuators to alter tilt about the perpendicular axes. Make directional corrections to beam positioning or focus, using the fixed reference point as the stable baseline. The result should be a repeatable orientation suited to the intended imaging, excitation, or trapping path.
These mounts support systems that require controlled laser or reflective-path alignment, including fluorescence excitation paths, imaging systems, and optical trapping instruments. In microscopy and biosensing, the controlled orientation helps direct light through the intended optical path. In cell manipulation, optical trapping, and biological-sample analysis, stable alignment supports more consistent positioning and measurement.
Accurate angular adjustment improves beam positioning and focusing, which can make optical measurements more consistent. That effect is relevant when researchers analyze biological samples quantitatively or use fluorescence excitation to generate imaging signals. By providing repeatable control of the reflective path, the mount helps maintain comparable optical conditions across microscopy, biosensing, and cell-focused experiments.
