Abstract: An apparatus includes first and second hardware components. The first component includes at least one first input configured to receive at least one first data or power signal, at least one voltage clamping circuit configured to limit a voltage of the at least one first data or power signal, and at least one first output configured to provide the at least one voltage-limited first data or power signal. The second component includes at least one second input configured to receive at least one second data or power signal, at least one limiter circuit configured to limit an amount of energy in the at least one second data or power signal, and at least one second output configured to provide the at least one energy-limited second data or power signal. The at least one second data or power signal comprises or is based on the at least one voltage-limited first data or power signal.

Abstract: A meter case used with a utility meter is disclosed. The meter shell includes a plurality of snap fit joints assembled on the meter case arranged to engage a module cover to mount the module cover to the meter shell. The module cover further includes wire housing formed along an inner periphery of the module cover that houses a wire having a first end and a second end therein. A metal shield placed behind the meter shell is electrically coupled to a first connector. A terminal electrically connected to the metal shield is arranged to discharge current to ground. An electrical contact electrically coupled to the second end of the wire is arranged to engage the first connector to establish an electrical connection to the metal shield for the discharge to ground of electrostatic currents sensed by wire.

Abstract: A power conditioning circuit includes at least one power storage device having electrodes coupled for receiving power from a DC power source. At least one active current limit (ACL) circuit coupled to the electrodes of the power storage device is for limiting a maximum power output from the power storage device under fault conditions. A DC-to-DC converter has its inputs coupled to the ACL circuit. At least one crowbar circuit has a first terminal and a second terminal and a shorting device coupled to an output of the DC-to-DC converter for providing output terminals for the power conditioning circuit.

Abstract: A packaged cellular modem system includes a capacitor for receiving power from a DC power source, a DC-to-DC converter coupled to capacitor electrodes, a cellular modem coupled to the converter output and to an antenna, and an IS barrier circuit coupled to a modem output. A microcontroller coupled to a boost regulator has its output coupled to electrodes. A metrology jumper is between the microcontroller and ground. An encapsulation material provides a potted area for the capacitor, converter, modem, IS barrier circuit and microcontroller. A SIM card is coupled to the modem by the IS barrier circuit. LED's are coupled to the microcontroller. The SIM card and LEDs are in a non-potted area. A transparent SIM card access cover over the SIM card and LEDs enables exposing the SIM card.

Abstract: A system and method for updating industrial cellular communications devices. A supercapacitor and a cellular modem are connected electronically to one another. A host can communicate bidirectionally and wirelessly with the cellular modem. A microcontroller is connected electronically with the cellular modem, such that the microcontroller facilitates monitoring with the cellular modem of a voltage and temperature associated with the super capacitor. When the voltage of the super capacitor attains a lower voltage limit, the cellular modem stops receiving data from the host and sends a status code to the host and disconnects a data call and data transfer and enters into a sleep mode during which time the super capacitor is recharged. The cellular modem can reestablish the data call with the host after the super capacitor has been recharged.
