A system for monitoring the contents of a closed container is provided. The system includes a sensing system for monitoring the contents of the container; a signal receiving element for receiving sensor data from the sensing system; a control element for analyzing received sensor data; a first transceiver element for receiving signals containing sensor data from within the container and for transmitting those signals outside of the container; and a satellite transceiver element for receiving signals from the first transceiver element and for forwarding the received signals via satellite uplink to a remote location.

Components for use in a temperature controlled heatable object are provided in which a temperature sensor is connected to a transmitter such as a Radio Frequency Identification (RFID) tag. The RFID tag is encased in a protective overmolding and connected to the temperature sensor via a mineral insulated cable. An end cap containing a potting material (such as silicone or ceramic) is placed over the temperature sensor and laser welded to a sheathing of the mineral insulated cable. A potting material for use in a heatable object is also provided comprising a silicone-based material that is modified by adding bauxite to increase thermal conductivity.

An air monitoring system is disclosed having an air monitoring unit with at least one sensor for measuring data of an air quality parameter and a computer for storing the air quality parameter data received from the sensor. The air monitoring unit may use an installed or a portable system, or a combination of both, for measuring the air quality parameters of interest. A remote data center may be provided, and the data may be uploaded to the data center from the unit by a communications media such as the Internet. Information or instructions may also be downloaded from the data center to the unit via the communications media for controlling or modifying the function of the unit. An expert system may be provided with the air monitoring system for controlling the unit. The information or instructions downloaded to the unit may be generated by the expert system.

A weather station (100) for indicating weather conditions, comprises a casing (110) having a screen (120) and an internal electronic operating circuit (90). The operating circuit (90) includes at least one sensor (70) for sensing an atmospheric parameter and a microprocessor (80) for ascertaining a weather condition based on the sensed atmospheric parameter and indicating the weather condition on the screen (120). The operating circuit (90) includes a memory (60) which stores several sets of images, each set representing a corresponding variation of the weather condition, for selection by the microprocessor (80) to indicate the weather condition in the variation as ascertained in an animated representation.

Method, system and device useful with conventional personal computers respond automatically to an identified alarm sound by sending a notification signal via the Internet only when a special sound monitoring program is active. Additionally, bedside detection of acoustic alarms is combined with enhanced waking devices to insure the waking of a child or hearing impaired person in response to an emergency. Home safety and security are provided using a bedside unit to monitor audible safety and security alarms and send notification signals to the appropriate communication site. A health monitoring method and system utilizes the bedside device to monitor breathing patterns and other health measuring signals and communicate these patterns and signals to a medical monitoring station.

A climate control system having two or more stages of cooling operation or heating operation is provided for supplying conditioned air to a plurality of zones within a space, where the climate control system comprises a plurality of controllable zone dampers for controlling the supply of conditioned air to each of the plurality of zones, and a plurality of zone temperature sensors for periodically sensing temperature at preset intervals and transmitting sensed temperature information when the temperature of the zone has changed by more than a predetermined amount. The climate control system further comprises a thermostat that is adapted to initiate operation of the circulating air blower and the cooling system at less than full capacity when at least one zone temperature sensor transmits a sensed temperature that differs from the set point temperature by more than a specific amount, wherein the thermostat switches the circulating air blower and cooling system to full capacity operation when either the cooling system has operated at less than full capacity for more than a predetermined time or when more than a predetermined number of zone temperature sensors transmit sensed temperatures that differ from the set point temperature by more than a specific amount.

A system for remotely monitoring operations of an HVAC system such as a chiller system having a control center, or a rooftop unit. The system utilizes a remote monitoring unit (RMU) located on-site. The RMU is in one-way communication with the component of the air conditioning system and receives data indicative of the operation of the component and determines whether the component is operating outside the normal operating parameters. When the RMU determines, from the data, that there is a problem that is within a critical parameter range, then a critical alarm is generated and the RMU opens a line of communication with a remote monitoring diagnostics device (RMD) located at the facility of the HVAC or refrigeration manufacturer and downloads the information to the RMD which determines whether remedial action is required and initiates remedial action if required.

A system for detecting water leaks is described. In one embodiment, the system includes a plurality of sensors, selected from a moisture sensor, a water level sensor, and / or a water temperature sensor. A processor collects moisture readings from the sensors. In one embodiment, the processor reports a possible water leak when a moisture sensor detects moisture above a moisture threshold value. In one embodiment, the processor report a water leak when the water level reading exceeds a water threshold value and / or when the temperature reading exceeds a temperature threshold value.

A cooking apparatus with an information exchange system that involves an assembly featuring a cooking apparatus such as a smoker or an electric turkey fryer and an information exchange system that provides for local and / or remote monitoring of cooking characteristic that preferably includes food item temperature probing that is displayed externally on the cooking appliance as in a local remote cooking characteristic information conveyance device that are preferably either in unidirectional of bi-directional.
