By controlling the current in the array the focal point can be moved around, and with it the robot.
For imaging this focal point can be scanned in the x- and y- directions.
It would be ideal to have a focused ultrasonic transducer whose focal point can be scanned together with the scanning laser focus without mechanically scan the transducer.
A focal point can be artwork, a window, a fireplace or a television; arrange all the furniture to face it.
An unsolved problem in the interval-valued belief structure is the existence of maximal confidence intervals, referring to the credible and maximal interval-valued beliefs assigned to focal elements, in which every point can be reached by a combination rule.
Instead they were displaced axially above the focal point, as can be seen by the defocused rings stemming from the scattering of the Janus particles in dark-field images.
Every room benefits from a center of attention, or focal point, which can be any object or area that attracts the eye and gives you something to orient your other furniture around.
Going back to the case of the response of mammalian cells' cytoskeletons, the recruitment of actin seen at focal adhesion points can also be at least partially recapitulated by artificially exerting forces on other locations of the cells [ 21].
Furthermore, cultivating shared interests and sentiments provides networks of focal points around which coordination can be increasingly facilitated.
By using ultrasonic transducers that emit interfering sound waves to a focal point, a virtual object can be perceived by touch.
