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.
Claims15
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;
- such that a transition, in the 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.
