Abstract

Systems, method and apparatuses of a building control sensor unit are disclosed. One apparatus includes a building control sensor unit that includes one or more sensors operative to sense an environmental condition of a structure, and a transceiver, wherein the transceiver includes an extended antenna, wherein the extended antenna includes a strand of memory metal. The apparatus further includes a controller, wherein the controller is operative to receive information from other building control sensor units or a central controller, and transmit information to the other building control sensor units or the central controller, wherein the building control sensor unit is configured such that when placed on or within a ceiling of the structure, the extended antenna extends into the structure.

Claims

1. A building control sensor unit, comprising:

one or more sensors operative to sense an environmental condition of a structure;

a transceiver, wherein the transceiver includes an extended antenna, wherein the extended antenna includes a strand of memory metal, wherein the strand of memory metal is configured to maintain an extended shape even when temporarily deformed;

a controller, wherein the controller is operative to receive information from other building control sensor units or a central controller, and transmit information to the other building control sensor units or the central controller;

wherein the building control sensor unit is configured whereby when placed on or within a ceiling of the structure, the extended antenna extends into the structure.

2. The building control sensor unit of claim 1, wherein the building control sensor unit comprises a circuit board that provides an electrical interface between the extended antenna and the controller.

The building control sensor unit of claim 3, wherein the extendable antenna maintains electrical contact with the conductive receiving unit due to the conductive receiving unit being deformed around at least a portion of the extendable antenna, and wherein the extendable antenna is a fixed position due to the conductive receiving unit being deformed around the at least the portion of the extendable antenna.

5. The building control sensor unit of claim 1, wherein the building control sensor unit is enclosed within a metallic enclosure, and the extended antenna extends out of the metallic enclosure and into the structure.

6. The building control sensor unit of claim 1, wherein the extended antenna is functional to deform from an operational position during shipping of the building control sensor unit, and spring back to the operational position when deployed for operation.

7. The building control sensor unit of claim 1, wherein the memory metal of the extended antenna includes a Nickel Titanium alloy.

8. The building control sensor unit of claim 1, wherein the extended antenna includes a single strand of memory metal.

9. The building control sensor unit of claim 1, wherein the extended antenna includes multiple strands, and other memory metal antenna configurations.
