Patent number: 11994546Abstract: An impedance sensing circuit includes three impedance elements and a sensing element arranged in a bridge configuration. A first input terminal is coupled to two of the impedance elements to apply a stimulus signal. In a mutual-sensing mode, a second input terminal is coupled to the third impedance element and the sensing impedance element to apply an opposite phase stimulus signal. The impedance sensing circuit may be configured in a self-sensing mode, in which the opposite phase stimulus signal is decoupled from the third impedance element and the sensing impedance element. At least one of the impedance elements is variable and may be adjusted to balance an offset impedance load on the sensing element.Type: GrantFiled: May 17, 2022Date of Patent: May 28, 2024Assignee: Analog Devices, Inc.Inventors: Isaac Chase Novet, Steven J. Decker

Patent number: 11922500Abstract: The example methods and systems described herein provide for configuration of one or more trade order parameters to associate with one or more trade orders, where the trade orders may be submitted to one or more electronic exchanges. According to an example embodiment, rather than having the trader manually configure each individual parameter associated with each trade order, a trader can pre-configure customer and order parameters. A user, for example a trader, broker, or market maker, can configure trade order parameters to associate with one or more customers, one or more order types, and/or internal messages to associate with any of the configured customers or orders. Based on the selected customer and tradeable object, the trading system evaluates the pre-configured customer and associated order parameters and determines which trade order parameters best match. The trading system then dynamically populates the order entry window with the specific trade order parameters associated with the best match.Type: GrantFiled: November 19, 2021Date of Patent: March 5, 2024Assignee: Trading Technologies International, Inc.Inventors: Steven J. Carroll, Stephen P. Decker, Bharat Mittal

Patent number: 10056868Abstract: An electrical circuit includes a sensor configured to generate a current signal comprising a first portion comprising a contribution from a target source and/or a second portion comprising a contribution from sources other than the target source, a trans-impedance amplifier that amplifies the current signal and generate a low noise signal, and a high pass filter that converts the low noise signal into an AC signal having a positive amplitude, a negative amplitude, and a zero cross-over point between the positive and negative amplitudes. The circuit also includes a positive integrating amplifier that receives the positive amplitude of the AC signal and generates a positive integrated value over an integration period, and a negative integrating amplifier that receives the negative amplitude of the AC signal and generates a negative integrated value over the integration period. The circuit further includes at least one analog-to-digital converter that receives the integrated values.Type: GrantFiled: July 24, 2015Date of Patent: August 21, 2018Assignee: ANALOG DEVICES, INC.Inventors: Shrenik Deliwala, Steven J.

Patent number: 9733275Abstract: A current detection module capable of differentiating and quantifying contribution to a current signal generated by a sensor in response to stimulation by a certain target source from contributions from sources other than the target source (ambient sources) is disclosed. As long as the contribution from the target source comprises a pulsed signal, the module may synchronize itself to the pulse(s) so that there is a predetermined phase relationship between the pulse(s) and functions carried out by various stages of the module. The module may be re-used to also detect and quantify contributions from ambient sources by presenting these contributions to the module as pulses that trigger synchronization of the module. To that end, a detection system disclosed herein is based on the use of such current detection module and allows mode switching where, depending on the selected mode of operation, the module is configured to perform different measurements.Type: GrantFiled: July 24, 2015Date of Patent: August 15, 2017Assignee: ANALOG DEVICES, INC.Inventors: Shrenik Deliwala, Steven J. Decker, Gregory T. Koker, Dan M. Weinberg
