Abstract: A gas meter reading system is provided that allows automated meter reading capability to be incorporated with sealed mechanical type gas meters. The reading system is mounted to the window of the meter adjacent to the measurement dial. The reading system senses the rotation of the dial and provides data, such as a pulse, that may be recorded by an external source. A method of detecting for leaks with a gas meter having a reading system is also provided.

Abstract: A monitoring system is provided that allows for monitoring and reporting of operational parameters for processes and devices in a subterranean environment. The system includes a plurality of interface devices coupled to sensors at a desired process or device. The interface devices transmit the measured data to a coordinator device through a personal area network. The coordinator device aggregates data from multiple interface devices and transmits the data to a remote service through a communications network.

Abstract: An optical sensor for detecting motion or movement in an area of interest is provided. The optical sensor includes a base having optical filtering properties. A sensor assembly having a light emitting diode, a CMOS sensor and a pair of lens is mounted to said base. The CMOS sensor has a range of wavelengths of light to which it has an increased sensitivity. The optical filtering properties of the base are ranged to absorb wavelengths of light in the range of increased CMOS sensor sensitivity. In this way, the effects of ambient light on the optical sensor are reduced.

Abstract: An optical sensor for detecting motion or movement in an area of interest and a method of operation is provided. The system includes a CMOS sensor having an array of pixels that captures images in an area of interest. The system monitors the average pixel value for the array to define a first state. If the average pixel value changes beyond a defined threshold, the system defines a second state. For each change in state, a signal is generated. In one embodiment, the optical sensor is used with a meter having a dial with an indicator. The optical sensor generates a signal each time the indicator passes through the area of interest to allow for the remote monitoring of a consumable commodity.

Abstract: Systems and methods are disclosed for using 802.11 based wireless protocols in various energy management applications wherein a host controller uses various types of communication networks to distribute information to an on-premise processor that in turn uses 802.11 based wireless protocols to communicate with various types of end devices, such as utility meters. Various forms of communication are defined between the end device, the on-premise processor, and the energy management host for accomplishing power load control, including determining when to activate or deactivate a load, requesting permission to activate a load, reading usage data, activating or deactivating a meter, and determining rate schedules. A flexible scheme allows control to be shifted to be resident in various entities. The architecture is applicable not only for power load control, but other control type and metering devices.

Abstract: The invention involves systems and methods of providing energy to land-based telemetry devices wherein the energy storage and power conditioning system is comprised of an input power supply, an energy storage element, an output supply and a control system. The input power supply provides energy to the output power supply and charges the energy storage element. The energy storage element is comprised of one or more UltraCaps and supplies energy to the output power supply at times of peak need and when the primary energy source to the input power supply is removed. The control system adjusts the voltage supplied to the energy storage element by the input power supply according to changes in the ambient temperature to compensate for changes in the internal equivalent series resistance of the UltraCaps caused by the change in ambient temperature. The output power supply provides energy to the land-based telemetry device.
