A cellular modem is configured for low power applications. In some instances, the cellular modem includes a transceiver, a processor to control the transceiver, a memory device in communication with the processor, and a general-purpose input/output (GPIO) pin, controlled by the processor. In an example, the cellular modem receives an appointed time for an upcoming communication and determines a time to activate a power supply. The determination may be based at least in part on the appointed time for the communication, so that the power supply is ready to supply power at a level consistent with use of the transceiver at the appointed time of the communication. At the determined time, a signal from the GPIO pin is used to activate the power supply, resulting in an increase in power supplied to the cellular modem in a just-in-time manner.

Cellular modem for low power applications

Breakaway devices for use in a meter-pit environment that protect connections between components of an AMR system are described herein. In various embodiments, at least one cable is adapted to operably couple a first AMR device and a second AMR device, wherein at least one of the first AMR device and the second AMR device is disposed in a utility meter pit. In an embodiment, at least once connector adapted to operably couple the cable to the first AMR device or the second AMR device is constructed to be decoupleabe in response to a force that is less than the linear breaking strength of the cable. In another embodiment, the cable may be constructed to have a length equal to at least about twice the distance between the first AMR device and the second AMR device. A coupling member is provided that secures a portion of the cable in a generally coiled configuration, and the coupling member is constructed to be decouplable to release a portion of the length of the cable in the generally coiled configuration in response to a force that is less than the linear breaking strength of the cable. The systems and devices disclosed herein act to prevent overstress on system components and connections when force is applied to the cable connecting these components.

Antenna breakaway device for utility pit meter system

Utility meter modules, antenna modules, pit sets, and pit lid assemblies are described, with regard to automated meter reading (AMR) systems, that prevent metering signal attenuation, pit leakage, and battery drainage, along with other advantages, and which minimize the likelihood of damage and tampering.

Integrated meter module and utility metering system

A system and method for fast detection of specific on-air data rates are disclosed which, in one example embodiment, enable endpoint devices in automatic meter reading (AMR) systems to quickly determine the existence of over-the-air information that is specifically targeted to a unique class of AMR devices. An endpoint device utilizing the digital squelch circuit arrangement and algorithm of the invention can quickly and precisely determine if the AMR system is communicating with its class of AMR device by looking for a specific non-standard data rate present on the air. This method therefore allows for a significant improvement in battery life in two-way RF communication units by avoiding unnecessary data processing and data transmissions. The digital squelch method also enables even faster determination of inappropriate data rates and of no signal present situations, further improving battery life.

System and method for fast detection of specific on-air data rate

A low impedance encoder generally comprises a clock source and a switch. The clock source operates according to a predetermined duty cycle. The switch has a first position, closed, and a second position, opened. The duty cycle controls a current flow the switch. A high current flow through the switch indicates that the switch is closed and that the consumption of a utility as registered by the utility meter has occurred; the switch will continue to open and close throughout the process of metering. A low current flow through the switch indicates that the switch is open.
