    Abstract: A method of determining state of charge of an energy delivery device includes sampling voltage values of the energy delivery device during relaxation of the device. The method further includes regressing an open circuit voltage value and the total overpotential being relaxed. The regression includes a predetermined time constant of relaxation associated with the energy delivery device. One embodiment uses the equation V(t)=OCV?? exp(?t/tau), where V(t) represents the sampled voltage values, t represents times at which each of the voltage values are sampled, OCV represents the open circuit voltage value of the energy delivery device, ?represents the overpotential value, and tau represents the time constant of relaxation. The method uses a predetermined profile that relates open circuit voltage of the energy delivery device to state of charge of the device, to determine a particular state of charge corresponding to the regressed open circuit voltage value.

  • Patent number: 8803716
    Abstract: A chip with a built-in self-test (BIST) component capable of testing the linearity of an ADC is described herein. The BIST component uses hardware registers to facilitate a sliding histogram technique to save space on the chip. A subset of detected digital codes are analyzed, and DNL and INL calculations are performed by a controller to determine whether any of the digital codes in the subset exceed maximum or minimum DNL and INL thresholds. New digital codes being detected by the ADC are added to the subset as lower-value digital codes are pushed out of the subset, maintaining the same number of digital codes being analyzed as the subset moves from lower codes detected during lower voltages to higher codes detected at higher voltages. A synchronizer and pointer ensure that the subset moves through the digital codes at the same rate as the analog input ramp source.

  • Patent number: 8762109
    Abstract: Estimating impedance of energy storage devices includes generating input signals at various frequencies with a frequency step factor therebetween. An excitation time record (ETR) is generated to include a summation of the input signals and a deviation matrix of coefficients is generated relative to the excitation time record to determine crosstalk between the input signals. An energy storage device is stimulated with the ETR and simultaneously a response time record (RTR) is captured that is indicative of a response of the energy storage device to the ETR. The deviation matrix is applied to the RTR to determine an in-phase component and a quadrature component of an impedance of the energy storage device at each of the different frequencies with the crosstalk between the input signals substantially removed. This approach enables rapid impedance spectra measurements that can be completed within one period of the lowest frequency or less.

    Abstract: A circuit for direct current (DC) offset estimation comprises a quantile value circuit and a signal processor. The quantile value circuit determines a plurality of quantile values of an input signal and includes a plurality of quantile filters. Each quantile filter includes a comparator, a level shifter, a monotonic transfer function component, and a latched integrator. The comparator compares the input signal and a quantile value. The level shifter shifts the output of the comparator. The monotonic transfer function component determines the magnitude of the shifted signal and provide a transfer function signal. The latched integrator suppresses transient characteristics of the transfer function signal and provide the quantile value. The signal processor is configured to calculate a weighted average of the quantile values to yield a DC offset estimate.

  • Patent number: 8731882
    Abstract: Improved convergence in the volume-integral method (VIM) of calculating electromagnetic scattering properties of a structure is achieved by numerically solving a volume integral equation for a vector field, F, rather than the electric field, E. The electric field, E, is determined from the vector field, F, after solving of the volume integral equation. The vector field, F, may be related to the electric field, E, by a change of basis, and may be continuous at material boundaries where the electric field, E, has discontinuities. Convolutions of the vector field, F, are performed using convolution operators according to the finite Laurent rule, which allows for efficient matrix-vector products using Fast Fourier Transforms. An invertible convolution-and-change-of-basis operator, C, is configured to transform the vector field, F, to the electric field, E, by performing a change of basis according to material and geometric properties of the periodic structure.

  • Patent number: 8725303
    Abstract: A multi-dimensional energy control system is provided with an energy management software application that organizes the consumption of energy by a device as an n-dimensional energy space, where n is an integer greater than 2, and each axis in the energy space represents an energy consumption characteristic. The energy management application generates instructions for a device in response to calculating a compromise operating point in the energy space. A user interface (UI) connected to the energy management application has a display to receive a graphical representation of the energy space and compromise operating point, and an input to receive user commands for moving the represented compromise operating point in the represented energy space. The energy management application calculates the compromise operating point in the energy space to match the displayed compromise operating point.

  • Patent number: 8719123
    Abstract: A circuit breaker having internal power monitoring and data signal generating apparatus, and a system for utilizing such a circuit breaker in a facility having a plurality of tenants served by branch circuits from a plurality of distribution panels. The circuit breaker radiates signals indicative of power consumption of the branch circuit protected thereby, together with a unique address identifier tied to one tenant. Electrical billings are based on summing all signals for each tenant. Changes to branch circuits during tenancy will not disturb correct billings since individual circuit breakers are associated with that tenant using power supplied by each branch circuit. Hence changes to branch circuits may be limited to modify building space locations served by the modified branch circuit, and need not be further modified to maintain correct billing in light of the circuit changes.
