Abstract
Devices, methods, and systems for event monitoring and detection device testing are described herein. One device includes a memory and a processor to execute instructions stored in the memory to operate a sensor of the event monitoring and detection device at a first sensitivity level, operate the sensor of the event monitoring and detection device at a second sensitivity level, and return the sensor of the event monitoring and detection device to the first sensitivity level.
Claims20
A controller for an event monitoring and detection device, comprising:
- a memory;
- and
- a processor configured to execute executable instructions stored in the memory to:
- operate a sensor of the event monitoring and detection device at a first sensitivity level;
- operate the sensor of the event monitoring and detection device at a second sensitivity level;
- and
- return the sensor of the event monitoring and detection device to the first sensitivity level.
An event monitoring and detection device, comprising:
- a light source configured to emit a beam of light;
- a sensor configured to:
- receive the beam of light and produce a first signal associated with the beam of light;
- and
- receive a scattered portion of the beam of light and produce a second signal associated with the scattered portion;
- and
- a controller configured to provide a notification responsive to:
- a decrease in the first signal that exceeds a decrease threshold;
- and/or
- an increase in the second signal that exceeds an increase threshold.
A method, comprising:
- operating a first portion of a sensor of an event monitoring and detection device at a first sensitivity level;
- operating the first portion of the sensor of the event monitoring and detection device at a second sensitivity level;
- and
- returning the first portion of the sensor of the event monitoring and detection device to the first sensitivity level;
- receiving a first signal and a second signal produced by a second portion of the sensor, wherein the first signal is associated with a beam of light, and wherein the second signal is associated with a scattered portion of the beam of light;
- and
- providing a notification responsive to:
- determining that a decrease in the first signal exceeds a decrease threshold;
- or
- determining that an increase in the second signal exceeds an increase threshold.
