SENSOR CONFIGURATION
First Claim
1. A sensing system for detecting an object, comprising:
- a first sensor arrangement comprising;
a first passive sensor configured to;
responsive to detecting a presence of an object, send a wakeup signal to a first active sensor for triggering the first active sensor to awaken from a sleep state; and
the first active sensor configured to;
responsive to receiving the wakeup signal from the first passive sensor, transition from the sleep state to an active state; and
while in the active state;
detect at least one of motion or distance of the object within a first detection zone to create object detection data; and
transition from the active state to the sleep state.

Abstract
One or more techniques and/or systems are provided for detecting an object, such as a person. For example, a sensing system may comprise a sensor arrangement. The sensor arrangement may comprise a passive sensor and an active sensor. The active sensor may be placed into a sleep state (e.g., a relatively low powered state) until awakened by the passive sensor. For example, responsive to detecting a presence of an object (e.g., a nurse entering a patient'"'"'s room), the passive sensor may awaken the active sensor from the sleep state to an active state for detecting motion and/or distance of the object within a detection zone to create object detection data (e.g., an indication of a hygiene opportunity for the nurse). The active sensor may transition from the active state to the sleep state responsive to a detection timeout and/or a determination that the object left the detection zone.

18. A method for detecting an object, comprising:
-
invoking a first passive sensor to; responsive to detecting a presence of an object, send a wakeup signal to a first active sensor for triggering the active sensor to awaken from a sleep state; and invoking the first active sensor to; responsive to receiving the wakeup signal from the first passive sensor, transition from the sleep state to an active state; and while in the active state; detect at least one of motion or distance of the object within a first detection zone to create object detection data. - View Dependent Claims (19)

20. A sensing system for detecting an object, comprising:
-
a first sensor configured to; responsive to detecting a presence of an object, send a wakeup signal to a second sensor; and the second sensor configured to; transition from a sleep state to an active state based upon the wakeup signal received from the first sensor; and while in the active state; detect at least one of motion or distance of the object within a first detection zone to create object detection data; and responsive to at least one of a detection timeout or a determination that the object has left the first detection zone, transition from the active state to the sleep state. - View Dependent Claims (21, 22)
