REMOTE MONITORING SYSTEM
First Claim
1. A method of communicating information in an environmental monitoring system, the environmental monitoring system comprising at least one computing device and a plurality of remote units located remote from the at least one computing device, each remote unit of the plurality of remote units comprising a sensor to sense an environmental parameter and a transceiver, the method comprising:
- in response to receiving a message at the at least one computing device from a remote unite of the plurality of remote units and determining that the message satisfies at least one condition, transmitting from the at least one computing device an acknowledgement to the remote unit from which the message was received, the acknowledgement indicating a scheduled time for the remote unit to transmit a second message to the at least one computing device.

Abstract
A temperature monitoring service in which remote monitoring units are distributed to customers who then set up monitoring as desired at their facilities. The devices may be registered through a web site using the Internet. Monitoring information may be communicated using a publicly available, wireless network, such as a cellular telephone network. The service may be provided with a system, including a server, which can deliver high levels of monitoring functionality. The server may support streaming monitoring information to a customer for analysis or sending a command activating a device connected to a remote unit. Remote units associated with the same location may be in a pool, comprising one active unit and one or more spare units, in which the server automatically identifies the active unit. The server may support analyzing monitoring information according to an expected cycle pattern of a ventilation system at the monitored facility.

14. An apparatus comprising:
-
at least one processor; and at least one computer-readable storage medium having encoded thereon executable instructions that, when executed by the at least one processor, cause the at least one processor to carry out a method of communicating information in an environmental monitoring system, the environmental monitoring system comprising at least one computing device and a plurality of remote units located remote from the at least one computing device, each remote unit of the plurality of remote units comprising a sensor to sense an environmental parameter and a transceiver, the method comprising; in response to receiving a message at the at least one computing device from a remote unite of the plurality of remote units and determining that the message satisfies at least one condition, transmitting from the at least one computing device an acknowledgement to the remote unit from which the message was received, the acknowledgement indicating a scheduled time for the remote unit to transmit a second message to the at least one computing device. - View Dependent Claims (15)

16. A method of communicating information in an environmental monitoring system, the environmental monitoring system comprising at least one computing device and a plurality of remote units located remote from the at least one computing device, each remote unit of the plurality of remote units comprising a sensor to sense an environmental parameter, a transceiver, and a storage, the method comprising acts carried out by a remote unit of:
-
transmitting, to the at least one computing device, a message comprising data and error detection information; in response to receiving from the at least one computing device, as a response to the transmitting, a negative acknowledgement, retransmitting the message; and in response to receiving from the at least one computing device, as a response to the transmitting, an acknowledgement indicating a scheduled time for the remote unit to transmit at least one second message to the at least one computing device, storing on the storage of the remote unit information indicating the scheduled time for remote unit to transmit the at least one second message. - View Dependent Claims (17, 18, 19, 20)
