摘要： Battery cell charge equalization devices, systems and methods are provided. A particular method includes receiving a charging current at a battery charge equalization circuit coupled to a battery cell of a multi-cell battery. The method also includes routing at least a portion of the charging current away from the battery cell when a voltage of the battery cell satisfies a first voltage threshold. The method further includes establishing a second voltage threshold in response to the voltage of the battery cell satisfying the first voltage threshold. The second voltage threshold is lower than the first voltage threshold. The charging current is routed away from the battery cell while the voltage of the battery cell satisfies the second voltage threshold.

摘要： An electro-magnetic device for use in applications requiring low-profile components. The device includes a magnetic substrate with a scheme of through-holes in association with a first and second winding, plated or wired, integral to the substrate and wound orthogonal to each other.

摘要： A device for augmenting the control of a forced air furnace includes a heat probe which is located in association with a furnace heat exchanger so as to sense the air temperature of air passing across the heat exchanger. The probe is connected via a buffer to an optical controlled switch. A latch is associated with both the probe and the switch such that in response to a high temperature turn off point the optical coupled switch shuts off the furnace solenoid associated with the furnace and maintains the solenoid in an off position until the probe senses a low temperature turn on point. Upon sensing the low temperature turn on point the solenoid is turned back on and is maintained in the on position by the latch until the high temperature point is again reached.
