Abstract: Liquid or gel antimicrobial compositions are described. The compositions comprise enzyme that is able to convert a substrate to release hydrogen peroxide; and substrate for the enzyme. The compositions do not comprise sufficient free water to allow the enzyme to convert the substrate, or have a water activity (aw) of 0.7 or less. The compositions may comprise polymer, and there may be greater than 50%, by weight, of the polymer and/or less than 20%, by weight, of sugar in the composition. The compositions may comprise non-aqueous solvent, no honey and 5% or less, by weight, of the substrate in the composition. There may be greater than 50%, by weight, of the non-aqueous solvent and/or there is less than 20%, by weight, of sugar in the composition.

Abstract: An apparatus includes a first jaw (108) coupled to a second jaw (110) to form an opening (114) when the first jaw (108) and the second jaw (110) are closed. An aligning structure couples to at least one of the first jaw (108) and the second jaw (110). A portion of the aligning structure may be disposed within the opening (114) and aligns a power line (128) to a sensor (418) disposed within the first jaw (108) and the second jaw (110).

Abstract: A method, system and device for synchronizing a time period over which energy measurements are accumulated for an energy monitoring system including a plurality of energy monitoring devices is described. The method comprises transmitting a first radio frequency packet from a time reference device via at least a first and a second of the plurality of energy monitoring devices to a third of the plurality of energy monitoring devices. The method further comprises adjusting a time register within the third energy monitoring device based on the reception of the packet. The method further comprises accumulating a measure of energy consumption by the third energy monitoring device of a load coupled with the third energy monitoring device. The method further comprises transmitting the measure of energy consumption from the third energy monitoring device via at least a fourth and a fifth of the plurality of energy monitoring devices to a data aggregation device.

Abstract: A meter for measuring power parameters on one or more electrical power lines/loads is configured to operate with our without a removable metering options module. The meter includes a meter housing designed and dimensioned for rack mounted installation in a bay of an equipment rack or cabinet, and metering circuitry configured to provide revenue accurate metering and power quality analysis for a power line/load. The metering options module may be mounted to an externally accessible surface of the meter to change the functionality of the metering circuitry without increasing the dimensions of an outer envelop of the meter, and without disturbing tamper-proof seals included on the meter.

Abstract: A sensor apparatus for measuring power parameters on a power conductor, such as a high voltage transmission line may include a corona structure, an electronics assembly and a conductor mountable device. The corona structure may define an outer boundary surrounding the electronics assembly and the conductor mountable device. The corona structure may shield the electronic assembly and conductor mountable device from a corona produceable with the power conductor. The conductor mountable device may be a power parameter measurement device, such as a current sensor assembly. The current sensor assembly may be a split-core design that includes multiple transformer cores. The electronics assembly and the conductor mountable device may powered from a line voltage suppliable on the power conductor. Data may be wirelessly transmitted and received with the sensor apparatus.

Abstract: Systems and methods for reclassifying instrument transformers. A line mounted device that includes a sensor that can be attached to a power line. The line mounted device generates data or representations of the power parameters of the power line. A processor in the line mounted device produces modified representations of the power parameters that are transmitted wirelessly to a microprocessor based device. The microprocessor based device also receives second representations of the power parameters from legacy instrumentation. Compensation data is produced based on the modified representations from the line mounted device and the second representations from the legacy instrumentation. The compensation data can be used to compensate or correct the representations of the power parameters from the legacy instrumentation even after the line mounted device is no longer attached to the power line.

Abstract: A system and method for detecting and responding to device tampering in an EM device is disclosed. The EM device is provided with mechanisms to detect and indicate unauthorized tampering with the device. Further, in response to detected unauthorized tampering, the device may take actions to protect the integrity of data generated by the device as well as protect any confidential data stored within the device. Such actions may include preventing further device operation, generating warnings to the device owner/user, marking subsequently generated data as suspect, destroying stored confidential data, etc.
