1. A system to encourage compliance with hand washing procedures, the system comprising:
- a first beacon, associated with a boundary, to transmit a first identification signal; and
a second beacon, associated with the boundary, to transmit a second identification signal;
wherein a transition, in a vicinity of the boundary, between the first identification signal and the second identification signal indicates the boundary,wherein the first beacon emits a first beam that carries the first identification signal and has a transverse cross-section having a maximum length along a first axis, wherein the first beacon is oriented with the first axis of the first beam substantially parallel to the boundary.

Abstract
Among other things, systems to encourage compliance with hand washing procedures can include: an infrared emitter that projects a first infrared beam with a transverse cross-section having a first axis and a second axis that is shorter than the first axis, the transverse cross-section having a maximum length along the first axis, the infrared emitter modulating the first infrared beam to transmit a first identification signal; wherein the infrared emitter projecting the first infrared beam is placed such that the first axis of the transverse cross-section of the first infrared beam is substantially parallel to a boundary.
