PHOTOELECTRIC PEOPLE COUNTING DEVICE |
| 摘要 |
Embodiments of the invention may include a low-power people-counting system and related methods. Such a system may include a pair of uncollimated light sources operating at a relatively low duty cycle. Light from the sources may be detected using devices adapted to discriminate between light based on the source from which it was omitted. |

1. A low-power people-counting system, comprising:
at least a first uncollimated light source, wherein the first light source operates according to a duty cycle between about 0.1% and 10%; and at least a first light detector adapted to continuously and selectively sense radiant output of the first light source. |
