  • Dual detection sensor system for a washroom device
    Patent number: 7651068
    Abstract: A detection system for a washroom device evaluates outputs from an active sensor and a passive sensor to determine whether to activate the device (e.g., operate a valve in a sink or a lavatory). The active sensor has a transmitter that directs a light beam to a selected zone and a receiver that detects whether the light beam is reflected back to the sensor. The passive sensor detects changes in a temperature signature around the washroom device. A controller evaluates the outputs from both the active sensor and the passive sensor to determine how to operate the washroom device.

  • Sensor for washroom device with a non-circular sensing zone
    Patent number: 6894270
    Abstract: A washroom device sensor uses at least one infrared beam that forms a longitudinal, rather than spot-shaped, sensing zone for detecting the presence of a user. The increased detection area of the longitudinal sensing zone ensures that at least a portion of the beam will contact a user using the washroom device. The beam may be adjustable in two or more directions to generate two or more sensing zones in different positions, allowing optimization of the sensing zone location with respect to a particular washroom device and the anticipated position of the device user.
