Methods to prepare stable electrolytes for iron redox flow batteries

An iron redox flow battery system, comprising a redox electrode, a plating electrolyte tank, a plating electrode, a redox electrolyte tank with additional acid additives that may be introduced into the electrolytes in response to electrolyte ph. The acid additives may act to suppress undesired chemical reactions that create losses within the battery and may be added in response to sensor indications of these reactions.. ... Ess Tech Inc

Signal processor using multiple frequency bands

A circuit and method is disclosed for filtering an audio signal. The circuit has a first quadrature source and multipliers for multiplying the input signal by the i and q outputs of the quadrature source. ... Ess Tech Inc

Switchable four-pole jack for supporting balanced headphones and headset operation in mobile applications

An approach is disclosed for achieving improved sound quality from mobile ‘hifi’ playback devices by driving compatible headphones in ‘balanced’ or ‘differential’ mode via standard size headphone connectors, while retaining full compliance with legacy jack connections and allowing use of a microphone. When a headphone is connected, a smartphone may determine whether the headphone is one capable of accepting balanced audio signals, or one that uses a conventional 4-pole ctia or omtp jack. ...

Alternative low cost electrodes for hybrid flow batteries

A redox flow battery may include: a membrane interposed between a first electrode positioned at a first side of the membrane and a second electrode positioned at a second side of the membrane opposite to the first side; a first flow field plate comprising a plurality of positive flow field ribs, each of the plurality of positive flow field ribs contacting the first electrode at first supporting regions on the first side; and the second electrode, including an electrode spacer positioned between the membrane and a second flow field plate, the electrode spacer comprising a plurality of main ribs, each of the plurality of main ribs contacting the second flow field plate at second supporting regions on the second side, each of the second supporting regions aligned opposite to one of the plurality of first supporting regions. As such, a current density distribution at a plating surface may be reduced.. ... Ess Tech Inc

Internally manifolded flow cell for an all-iron hybrid flow battery

In one example, a system for a flow cell for a flow battery, comprising: a first flow field; and a polymeric frame, comprising: a top face; a bottom face, opposite the top face; a first side; a second side, opposite the first side; a first electrolyte inlet located on the top face and the first side of the polymeric frame; a first electrolyte outlet located on the top face and the second side of the polymeric frame; a first electrolyte inlet flow path located within the polymeric frame and coupled to the first electrolyte inlet; and a first electrolyte outlet flow path located within the polymeric frame and coupled to the first electrolyte outlet. In this way, shunt currents may be minimized by increasing the length and/or reducing the cross-sectional area of the electrolyte inlet and electrolyte outlet flow paths.. ... Ess Tech Inc

Electrolytes for iron flow battery

A method of operating an iron redox flow battery system may comprise fluidly coupling a plating electrode of an iron redox flow battery cell to a plating electrolyte; fluidly coupling a redox electrode of the iron redox flow battery cell to a redox electrolyte; fluidly coupling a ductile plating additive to one or both of the plating electrolyte and the redox electrolyte; and increasing an amount of the ductile plating additive to the plating electrolyte in response to an increase in the plating stress at the plating electrode. In this way, ductile fe can be plated on the negative electrode, and the performance, reliability and efficiency of the iron redox flow battery can be maintained. ... Ess Tech Inc

Programmable circuit components with recursive architecture

A circuit component that is adjustable at run time and a method of designing the circuit are disclosed. The component contains a hierarchy of recursive levels in which a bottom level is a compound element made from two connected simple elements, and each higher level contains two compound elements connected in the same fashion. ... Ess Tech Inc

Low noise audio rendering circuit

A circuit and method for lowering noise in an audio rendering system is described. An analysis is made of the spectral content of an audio signal, i.e., the frequencies it contains, over a certain time interval. ... Ess Tech Inc

Method and apparatus for achieving high-output signal swing from class-d amplifier

An apparatus and method are disclosed for providing output signal swings that are greater than the supply voltage in a class-d amplifier. The amplifier circuit boosts the voltage across the amplifier load, such as a loudspeaker, by using capacitors to “charge pump” the voltage across the load and thus increase the voltage temporarily. ... Ess Tech Inc

Apparatus and method for detecting and driving headphones differentially in mobile applications

An apparatus and method is disclosed for achieving improved sound quality from mobile ‘hifi’ playback devices by driving compatible headphones in ‘balanced’ or ‘differential’ mode via standard size headphone connectors on the device, while retaining full compliance with legacy jack connections and conventional headphones. When a headphone is connected, a smartphone may determine whether the headphone is one capable of accepting balanced audio signals, or one that uses a conventional 3-pole jack or a 4-pole ctia or omtp jack. ...
