Systems, methods and devices for use in measuring current through a conductor are provided. One example current device includes a first sensor configured to measure a first magnetic flux provided from a conductor and to generate a first signal proportional to the first magnetic flux, and a second sensor configured to measure a second magnetic flux provided from the conductor and to generate a second signal proportional to the second magnetic flux. The second sensor is spaced apart from the first sensor by a predetermined distance. The current device further includes a processor configured to determine, based on the first signal, the second signal and the predetermined distance, a radius between the conductor and at least one of the first sensor and the second sensor.

Insulated bags having at least three unitary layers of durable material are provided. In one embodiment, a first set of unitary layers of durable material forms a front wall, a bottom wall, and a rear wall. Two additional sets of unitary layers of durable material form side-walls. Edges of the two additional sets are joined to side and bottom edges of the first set by adding webbing and stitching together the joined edges and webbing. Disposed within the two inner most layers of the first set and the two additional sets is at least one layer of insulation. The first set and the second set are sealed at their top edge to secure the insulation. Horizontal webbing is attached to the bag via stitching through the horizontal webbing, each of the layers of the first set and the second set, and the at least one layer of insulation. Vertical straps are integrated into the bag between the horizontal webbing and the outer most layer of durable material of the first set. On the top of the bag is a mini-flap. Hook/loop fasteners are strategically positioned on the bag to secure access points on the bag. Optional features can be incorporated into the bag (e.g., side handles, a top handle, a durable bottom, a grommet, and a liner). Other embodiments of insulated bags are described herein (e.g., a bag that has the outer layer of the first set and the second set sandwiched between two layers of horizontal webbing).

A diagnostic system and a diagnostic method for a thermistor amplifier circuit are provided. The system includes a transistor electrically coupled to a controllable variable resistor having a predetermined resistance. The transistor applies a test voltage signal to the circuit indicative of a first temperature value. An amplitude of the test voltage value is indicative of a simulated thermistor temperature value. The microprocessor determines a test temperature value based on the amplitude of an output voltage of the circuit. The microprocessor also determines an inaccuracy value based on the test temperature value and the simulated thermistor temperature value.

A method for recording and having analyzed waveform data associated with an electronic circuit breaker having an electronic trip unit is disclosed. The electronic trip unit has a communication port and is capable of providing to the communication port a first signal representative of a phase current passing through the circuit breaker, and a second signal representative of a conditional event at the circuit breaker. The method includes facilitating the connection of a waveform recorder device to the communication port of the electronic trip unit; facilitating recording in a first memory of the waveform recorder device in a circular queue fashion information relating to the first signal received from the electronic trip unit; and, in response to the second signal received from the electronic trip unit, facilitating the stopping of the recording in the first memory.

A method of issuing and managing investment instruments called “Pension Shares” which preferably take the form of securities that represents a claim against and is secured by an investment fund. A Pension Share entitles its holder to receive, at a specified maturity date, either a lump sum payment amount or, at the option of said holder, to receive a sequence of annuity payments. The Pension Share issuer creates and manages the investment fund such that its net asset value at the maturity date will be adequate to make the lump sum payment or provide the holder with the annuity. A preferred form of Pension Share provides an annuity option of one dollar per for the life of the holder, or his or her survivor, both of whom are at a predetermined age at the maturity date. A Pension Share may be redeemed on demand in advance of the maturity date so that it may be exchanged for a Pension Share having a different maturity date if the holder's plans change.
摘要:
A method and system to improve efficiency and performance of a power supply by providing a consistent voltage level into a multiple-pole circuit breaker (10) to improve efficiency, reduce heat generation and increase the speed and consistency of “turn-on” times. A power supply (14) for changing waveform comprises circuitry for receiving at least one waveform having first and second components. Circuitry is provided for changing the first component and means for outputting a waveform comprising the outputs from the changing circuitry are also provided.
摘要:
A computer interface system that includes interactive interface controls as well as aural and kinetic interface controls to assist in educating a user, in profiling a user, and in controlling and monitoring the implementation of actions involving probabilistic distributions. The system allows the user to indicate, either directly or indirectly, a confidence level that he or she desires for actions such as investments, as well as other characteristics and constraints. The user is able to manipulate the interface controls to evaluate results in terms of confidence and risk. If the user approves the results and his or her profile, in a preferred embodiment the selections are transmitted to effectuate an action.
