First Claim
Patent Images
1. A method, comprising:
- provisioning a plurality of devices in a network, each of the devices configured to capture information regarding one or more of temperature or other environmental changes, stresses, accelerations or vibrations;
associating each device with one of a plurality of locations;
transmitting a middleware server request from provisioned devices;
assigning one of a plurality of middleware servers to each of the requesting devices; and
associating each of the requesting devices with an assigned middleware server.

Abstract
According to some implementations of the present invention, RFID devices and middleware servers are automatically provisioned with a network address and with instructions for sending a request for a middleware server to a middleware server assigner. In some implementations, the middleware server assigner is a load balancer. In some implementations, a middleware server is associated with a plurality of RFID devices by associating a middleware server network address or names with the network addresses of the RFID devices. Preferred methods also provide for redundancy of middleware servers and dynamic reassignment of RFID devices from an unavailable middleware server to an available middleware server.

13. A method, comprising:
-
provisioning each of a plurality of devices in the network, each of the devices configured to capture information regarding one or more of temperature or other environmental changes, stresses, accelerations or vibrations, wherein the provisioning comprises providing a device with a device network address and a designated load balancer; associating each device network address with one of a plurality of locations; causing devices to send a first middleware server request to a designated load balancer; assigning a first middleware server of a plurality of available middleware servers to a first plurality of the requesting devices; and making a correspondence between each of the first plurality of devices and the first middleware server. - View Dependent Claims (14, 15, 16, 17, 18)
