Multi-modal sensing
First Claim
1. A controller comprising:
- an output for controlling one or more lighting device to illuminate an environment;
an input for receiving a signal output from a sensor of a first type and a signal output from a sensor of a second type, wherein the sensor of the second type consumes more power than the sensor of the first type; and
a control module configured to detect motion of objects in said environment in response to receiving at least one of said signals, and control the one or more lighting device based on detected motion of objects in said environment, wherein the signal output from the sensor of the second type provides more accurate motion detection than the signal output from the sensor of the first type; and
wherein the control module is configured to disable the sensor of the second type, and use the signal received from the sensor of the first type to detect motion of objects in said environment when higher traffic density of objects passing through said environment occurs, and use the signal received from at least the sensor of the second type to detect motion of objects in said environment when lower traffic density of objects passing through said environment occurs.

Abstract
A controller comprising: an output for controlling lighting device(s)to illuminate an environment; an input for receiving a signal output from a sensor of a first type and a sensor of a second type, wherein the sensor of the second type consumes more power, but provides more accurate motion detection than the sensor of the first type; and a control module configured to detect motion of objects in the environment in response to receiving at least one of the signals, and control the lighting device(s) based on detected motion of objects. The control module configured to disable the sensor of the second type, and use the sensor of the first type to detect motion of objects when higher traffic density of objects passing through the environment occurs, and use at least the sensor of the second type to detect motion of objects when lower traffic density of objects occurs.

15. A computer program product for performing sensing using a signal output from a sensor of a first type and a signal output from a sensor of a second type to control one or more lighting device to illuminate an environment, the computer program product comprising code embodied on a computer-readable medium and being configured so as when executed on a processor to:
-
detect motion of objects in said environment in response to receiving at least one of said signals, and control the one or more lighting device based on detected motion of objects in said environment, wherein the signal output from the sensor of the second type provides more accurate motion detection than the signal output from the sensor of the first type; disable the sensor of the second type, and use the signal received from the sensor of the first type to detect motion of objects in said environment when higher traffic density of objects passing through said environment occurs; and use the signal received from at least the sensor of the second type to detect motion of objects in said environment when lower traffic density of objects passing through said environment occurs.
