Low-Cost Bicycle Lights vs. Cold Lights for Visualizing Neonatal Veins

Arbour lights

Amongst the theoreticians there was a subspecies who interacted with experimentalists — these theorists tried to make sure that their ideas were testable and that someone tested them. Preeminent amongst these was Francis Crick who wrote all the quotes above shown in red italics (taken from Crick’s autobiographical book What Mad Pursuit: A Personal View of Scientific Discovery; Basic Books, New ...

Bezier Lights

In this paper we introduce Bezier Lights, an intelligent lighting system that allows users to intuitively establish virtual boundaries in indoor environments. Boundaries can be easily created/modified by arranging the layouts of disk-shaped devices (“stones”) on the building floor. The immediate purpose of the system is to assist users in incorporating location-aware capabilities into private p...

Lights out.

Spot-lights for eye surgery.

Although operating microscopes are readily available in ophthalmic operating theatres certain procedures are more conveniently done without them and some surgeons prefer spot-lights rather than the large shadow-free theatre lamps. Single or twin spot-lights, unlike the large theatre lamps, produce little reflection off such tissues as the cornea which could obscure details of structures behind....

5.1 Unbalancing Lights

Consider a square n× n array of lights (see Figure 5.1). There is one switch corresponding to each row and each column (i.e., 2n switches). Throwing a switch changes the state of all the lights in the corresponding row or column. We now consider the problem of setting the switches so as to maximize the number of lights that are on, starting from an arbitrary initial on/off configuration of the ...
