Abstract: An electronic device includes a housing, an electrical power interface, two or more power channels, a metering circuit, and a metering verification (MV) port. The power interface receives AC power from an external power source. The first power channel delivers power from the power interface to a first load. The second power channel delivers power from the power interface to a second, independent load. The metering circuit is arranged to measure AC power supplied through the second power channel. The MV port is coupled to an output of the metering circuit, accessible through an opening in the housing, and configured to (a) allow power to be delivered to the second load when the MV port is not being used for determining metering circuit accuracy and (b) bypass the second load and permit attachment of an external controlled load when the MV port is being used for determining metering circuit accuracy.

Abstract: An apparatus for positioning and retaining a cable-styled device around an object includes a first member and a second member that are movable relative to each other. The first member includes a hinge element defining an opening proximate a first end of the first member, a hinge pin positioned within the opening, and a first retention element configured to receive a first section of the cable-styled device. The second member includes a generally hook-shaped element positioned at a first end of the second member and a second retention element configured to receive a second section of the cable-styled device. The hook-shaped element engages the hinge pin within the opening of the hinge element and is constructed to maintain engagement with the hinge pin when the first member and the second member are in an open position relative to each other.

Abstract: A object temperature monitoring apparatus includes a first housing configured for attachment to an object, such as an electrical distribution transformer, and a thermistor module coupled to or integrated with the first housing. The thermistor module includes a second housing and a thermistor. The second housing includes an elastic boot and a thermistor compartment adjacent to the elastic boot. The thermistor is positioned within the thermistor compartment and oriented to sense a temperature of the object when the first housing is attached to the object and the thermistor compartment is placed against a surface of the object. The elastic boot may be constructed to allow movement of the thermistor compartment when it is compressed against the surface of the object to enable the thermistor compartment to form a seal against the object's surface to prevent ambient air from affecting temperature measurements.

Abstract: An electronic device includes a housing defining a magnet attachment area, a bracket positioned in the magnet attachment area, and a magnet attached to the bracket. The bracket is configured to permit angular displacement of at least a portion thereof about an axis of rotation by no more than a predetermined displacement. The bracket may include a platform and a pair of spaced apart pivot arms. In such a case, the platform is configured to support the magnet and the pivot arms are attached to the platform at separate locations aligned along the axis of rotation. Alternatively, the bracket may include a platform, a pair of pivot arms, and a pin. The pivot arms may each define a respective pin aperture and be orthogonal to the platform and spaced apart such that the platform is positioned between them. The pin is positioned in the pin apertures of the pivot arms.

Abstract: A transformer monitor includes a housing and at least two connectors. The housing has a first end and a second end opposite the first end. A first connector is positioned proximate the housing's first end and configured for connection to a first cable assembly that outputs signals representative of a primary input current to the transformer. A second connector is positioned proximate the housing's second end and configured for connection to a second cable assembly that outputs signals representative of a secondary output current of the transformer. The connectors are oriented such that the first cable assembly extends away from the housing's first end in a first direction when the cable assembly is connected to the first connector and the second cable assembly extends away from the housing's second end in a second direction generally opposite to the first direction when the cable assembly is connected to the second connector.

Abstract: A pass-through antenna mount for a structure includes a base to be placed against an external wall of the structure and a shaft that extends from the base through an opening in the wall. The base defines an aperture therethrough. The shaft extends away from the base and defines a hollow channel extending along a length thereof. The channel is generally aligned with the aperture in the base. The shaft includes a neck portion and an adjacent body portion. The neck portion is configured to accept a fastener and the body portion defines a cable opening in a wall thereof. The cable opening fluidly communicates with the hollow channel. The antenna mount accepts an antenna mounted to the base, where the antenna cable(s) passes through the shaft and exits through the cable opening of the shaft's body portion, thereby taking a tortuous path through the antenna mount.

Abstract: A stud-mountable cable retention apparatus and system include a cable retention member, a stud engagement member defining a cavity therein, and a body member interconnecting the cable retention member and the stud engagement member. The cable retention member may be generally open-ended (e.g., C-shaped or U-shaped) and formed or partially formed of a flexible and resilient material. The cavity of the stud engagement member may be generally cylindrically shaped. The cable retention apparatus may also include an adjustable fastening member positioned about a periphery of the stud engagement member. The cable retention apparatus may further include one or more cable guide members connected at one end to the body member and extending away from the body member in one or more predetermined directions. The cable retention system may include two or more cable retention devices or apparatus interconnected by one or more cable guide members.
