Abstract: An apparatus and method for regulating a voltage to a load to compensate for one or more parasitic impedances. A first amplifier measures the voltage drop due to a first parasitic impedance, and a second amplifier measures the voltage drop due to a second parasitic impedance. An offset generator sums the first and second voltage drops with a reference voltage, and drives a DC-to-DC converter to produce an input voltage matching the summed voltages. Accordingly, the voltage at a load between the parasitic impedances matches the reference voltage. The load may be, for example, a computer microprocessor or central processing unit.

Abstract: A modular wireless repeater typically deployed with a roof-mounted tower-signal antenna and a base unit with a base unit antenna located within the building, to which the tower-signal antenna and the base unit are connected by the user or a satellite TV installer using a 75 ? coaxial cable. The system allows a customer to purchase a unit for all wireless service providers in a given frequency band, such as Cellular, PCS, GSM900, or DCS, etc., and then add on modules for additional types of service that the customer may desire in the future. The system also detects and prevents low-level oscillations. The wireless repeater also performs intelligent power control allowing it to function properly with near and far base unit antennas as well as near and far mobile stations.

Abstract: A molded case, cassette type circuit breaker for a multi-pole electrical distribution circuit includes a number of cassettes equal to the number of poles in the multi-pole electrical distribution circuit and a pin disposed through each cassette. The pin is formed from a dielectric material. The pin may be further disposed through a portion of an operating mechanism for aligning the cassettes and the operating mechanism. Each cassette may include a rotor, a pair of electrical contacts, and a contact arm supported in the cassette by the rotor. In this embodiment, the pin may be a cross pin that extends between each rotor. The dielectric material may include phenolic, melamine, silicone, epoxy, polyester, fiberglass and the like. Alternatively, the pin includes a steel bar coated with the dielectric material, where the dielectric material may include, for example, epoxy, silicon, Teflon, and the like. A pair of end caps may be disposed over end surfaces of the rotor.

Abstract: A smartphone profiler system and method is provided for collecting profile data from a mobile device which is then transmitted to a server for analysis and customer care. The profile data may be transmitted in one or more data streams. The invention provides for more than one possible type of transmission protocol. If a transmission fails using a first transmission protocol, the invention allows a second transmission protocol to be used. The server is preferably capable of invoking a corrective action on the mobile device based on the profile data received.

Abstract: A mobile care engine system is provided for delivering customer care to mobile devices, comprising. The mobile care engine system compares profile data from a mobile device with reference data and highlights any inconsistencies between the data, so that the device can be optimized. The inconsistencies are preferably determined using rule-based processing, and are automatically highlighted on the device display itself, or on a display of a customer service representative interface. Optionally, the system allows for corrective patches or settings to be sent to the device.

Abstract: A magnet assembly for actuating a trip latch in a circuit breaker. The magnet assembly includes a core and an armature. The core is disposed around a conductor forming a primary current path in the circuit breaker, and includes an end forming a pole face. The armature is biased by a force acting in a direction away from the pole face. The armature includes a generally planar surface and a projection extending from the generally planar surface toward the pole face. The generally planar surface is separated from the pole face by a first air gap, and the projection is separated from the pole face by a second air gap. The first air gap is larger than the second air gap.

Abstract: A trip system for a circuit breaker includes a current sensor and a stop surface, the current sensor having a contact surface, a first end that is supported, and a second end with a degree of freedom. The current sensor, arranged for receiving an electric current, undergoes a first deflection in response to a first current and a second deflection in response to a second current, the first deflection resulting in clearance between the contact surface and the stop surface, and the second deflection resulting in contact between the contact surface and the stop surface.

Abstract: A Mobile Care Framework is provided which uses an embedded diagnostic component, a device agent, to forward device profile data and receive update and problem solutions for implementation and execution with the device. Preferably, the data and solutions are communicated with a remotely located customer care application within the Mobile Care Framework using over-the-air communication.

Abstract: An operating handle assembly is provided having an improved handle engagement arrangement, thereby enabling the operating handle assembly to be adaptable for both human and machine interaction without the requirement of special attachment hardware. An operating handle assembly having a handle base and handle stem can accept a first handle extension suitable for human interaction or a second handle extension suitable for machine interaction. Assembly features provide for proper assembly of the handle extension to the handle stem while maintaining appropriate electrical clearances to live parts. The two part operating handle assembly, handle base with handle stem plus handle extension, provides for improved manufacturability of the host device, whereby the end-use construction of the host device need not be identified until a late point in the production cycle. The host device may be, but is not limited to, a standard circuit breaker, a rotary circuit breaker, a switch, or a disconnect device.
