Abstract

Various implementations relate generally to multi-sensor devices. Some implementations more particularly relate to a multi-sensor device including a ring of radially-oriented photosensors. Some implementations more particularly relate to a multi-sensor device that is orientation-independent with respect to a central axis of the ring. Some implementations of the multi-sensor devices described herein further include one or more additional sensors. For example, some implementations include an axially-directed photosensor. Some implementations also can include one or more temperature sensors configured to sense an exterior temperature, for example, an ambient temperature of an outdoors environment around the multi-sensor. Additionally or alternatively, some implementations include one or more of an infrared sensor or infrared sensors, a cellular communication circuit, and a GPS module.

First claim

What is claimed is:

1. An apparatus for tinting one or more windows, the apparatus comprising:
a structure having a closed circumference;
photosensors coupled to the structure and disposed in the structure and/or along the structure, the
photosensors configured to (I) sense sun radiation, and (II) generate data utilized in tinting the one or more windows of a building, the structure configured to enable the sun radiation to reach the photosensors, wherein at least one photosensor of the photosensors is a pyrometer, and wherein (A) the at least one photosensor that is the pyrometer comprises two or more photosensors that are pyrometers, and/or (B) (i) an axis of the pyrometer is parallel to (ii) an axis of at least one other photosensor of the photosensors; and
a connector communicatively coupled to the photosensors and configured for communicating the data between the photosensors and one or more controllers to control tinting of at least one of the one or more windows.

2. The apparatus of claim 1 , wherein one or more of the photosensors are configured to point skyward.

3. The apparatus of claim 1 , wherein the structure has a closed geometric circumference.

4. The apparatus of claim 3 , wherein the closed geometric circumference is a ring.

5. The apparatus of claim 1 , wherein the photosensors include a subset of photosensors that is disposed about a vertical axis and outward from the vertical axis.

6. The apparatus of claim 1 , wherein the apparatus is configured to couple to, or include, an ethernet port.

7. The apparatus of claim 1 , wherein the connector communicatively coupled to the photosensors and configured for communicating the data between the photosensors and the one or more controllers comprises cabling.

8. The apparatus of claim 1 , wherein (i) the axis of the pyrometer is parallel to (ii) the axis of the at least one other photosensor of the photosensors.

9. The apparatus of claim 1 , wherein the at least one photosensor that is the pyrometer comprises the two or more photosensors that are the pyrometers.

10. The apparatus of claim 1 , wherein (A) the at least one photosensor that is the pyrometer comprises the two or more photosensors that are the pyrometers, and (B) (i) the axis of the pyrometer is parallel to (ii) the axis of the at least one other photosensor of the photosensors.

11. A method of tinting one or more windows, the method comprising:
