  • Patent number: 8442785
    Abstract: One or more example diagnostics may be implemented as part of an intelligent luminaire manager or other radio frequency (RF) device that is in communication with an equipment or fixture such as a luminaire. Example diagnostics can determine a status such as a fixture malfunction, a cycling condition, a miswiring configuration, or another condition. The determined status can be wirelessly transmitted from the intelligent luminaire manager or other radio frequency device to a network server via a network. The network may be a network of intelligent luminaire managers and/or RF devices.

  • Patent number: 8254293
    Abstract: A network operating center for a network comprising known-location and unknown-location nodes can be configured to receive from each unknown-location node estimates of the distances from that node to each of its neighbor nodes. The network controller can then choose an initial location estimate for each unknown-location node and compute distances from the initial location estimates to the corresponding neighbor nodes. The network operating center can then choose subsequent location estimates of the unknown-location nodes by minimizing an error criterion based on a comparison of the received neighbor node distance estimates with the computed neighbor node distances.
