Publication number: 20220413054Abstract: Testing of a battery module can be conducted using monitoring electronics attached to the battery module. Stimulus can be applied to the battery module and removed. After removal of the stimulus, the monitoring electronics can collect signals from the monitoring electronics reflecting parameters of the battery module as it relaxes back to a non-stimulated state. The stimulus can be provided by test equipment or by components of a system in which the battery module, having attached monitoring electronics, is implemented. The monitoring electronics attached to the battery module can provide autonomous recording of signals associated with the battery module that can provide data regarding the status of the battery module or one or more batteries contained in the battery module.Type: ApplicationFiled: August 24, 2022Publication date: December 29, 2022Inventors: Shane O'Mahony, Joseph Caissie Bush, Colin G.

Patent number: 11448673Abstract: A device having an impedance measurement circuit that allows for reduction of flicker noise can be implemented in a variety of applications. A carrier suppression technique can be implemented that substantially removes the carrier signal with removal of noise artifacts associated with the carrier signal from sidebands of the carrier signal. Carrier suppression in an AC impedance measurement circuit can be implemented by sensing a carrier signal of the measurement circuit at a transmit location of the measurement circuit and subtracting a weighted version of the carrier signal at a receive location of the measurement circuit. One or more compensation impedances can be used such that the sidebands of the carrier signal are received with the carrier signal suppressed with respect to the receive location.Type: GrantFiled: November 3, 2020Date of Patent: September 20, 2022Assignee: Analog Devices International Unlimited CompanyInventors: Colin G.

Patent number: 9859878Abstract: A control circuit for use with a four terminal sensor, such as a glucose sensor. The Glucose sensor is a volume product and typically its manufacture will want to make it as inexpensively as possible. This may give rise to variable impedances surrounding the active cell of the sensor. Typically the sensor has first and second drive terminals and first and second measurement terminals, so as to help overcome the impedance problem. The control circuit is arranged to drive at least one of the first and second drive terminals with an excitation signal, and control the excitation signal such that a voltage difference between the first and second measurement terminals is within a target range of voltages. To allow the control circuit to work with a variety of measurement cell types the control circuit further comprises voltage level shifters for adjusting a voltage at one or both of the drive terminals, or for adjusting a voltage received from one or both of the measurement terminals.Type: GrantFiled: October 17, 2014Date of Patent: January 2, 2018Assignee: Analog Devices GlobalInventors: Colin G.
