Abstract: Systems and Methods disclosed herein relate to providing a message to an application programming interface (API). The message includes a request for data from a data model, a submission of data to the data model, or both; and a host selection between: a representational state transfer (REST) host and a subscription-based application programming interface (API) host, wherein the REST host receives REST-based messages and the subscription-based API host receives messages in accordance with a standard of the subscription-based API host; wherein the request for data, the submission of data, or both are configured to create, delete, modify, or any combination thereof data related to a smart-device environment structure, a thermostat, a hazard detector, or any combination thereof stored in a data model accessible by the API.

Abstract: A phase shifting diode detector system for an RFID reader. Quarter-wave delay circuitry is coupled between a forward transmitted signal of the RFID reader applied at a first end of the delay circuitry, and a reflected signal returning from an RFID tag applied at a second end of the delay circuitry. The system includes a pair of diode detector bridges, each comprising a series-coupled diode pair configured such that diode polarities in each bridge are reversed relative to the output thereof, to produce opposite rectified signal output polarities. An input to each of the bridges is capacitively coupled, from the junction between each said diode pair, to a respective opposite end of the delay circuitry.

Abstract: Systems and methods for configuring an RFID tag reader based upon one or more aspects of an environment of the RFID tag reader are disclosed. In one embodiment, a tag reader is deployed into an environment that includes readable RFID tags capable of storing dynamic data, and a characteristic of the environment of the tag reader is identified. Based upon the identified characteristic, the configuration of the tag reader is adjusted. In variations, the tag reader is configurable based upon information received from RFID tags. A method for enhancing RFID tag reading performance for example includes sending a first signal to each of a plurality of RFID tags. Information is received from at least one of the plurality of tags, at an RFID tag reader, and a configuration of the tag reader is adjusted based upon at least a portion of the received information.
