Abstract: A method is provided for marking a location on a surface of a component. The location defines a normal extending perpendicularly therefrom. The method includes irradiating the location with a first laser beam to create a first mark having a first color. The first laser beam is disposed at a first angle relative to the normal. The method also includes irradiating the location with a second laser beam to create a second mark having a second color different than the first color. The second laser beam is disposed at a second angle relative to the normal. The second angle is different than the first angle.

Abstract: A handwash station comprises a wall mounted cabinet which contains soap and water dispensing means, a proximity sensor and processing circuitry. The processing circuitry controls the dispensing of soap and water in response to signals from the proximity sensor. A count of valid handwashes is incremented only if a user's hand is detected by the proximity sensor at certain key points. The key points comprise at least the start of a last soap dispensing step and the start of a last rinsing water dispensing step. Differential valid handwash count values are stored periodically by the processing circuitry and can be downloaded to a central station for analysis.

Abstract: An automatic handwash apparatus (1) is provided with an input device (50) so that a user can be identified after a handwash operation has been completed. Since the input device is used after each handwash, it does not become a vector for cross-contamination.
