Publication number: 20180358828Abstract: A system and method is described for rapid charging and power management of a battery for a meter. A charger component is operably associated with the meter and is capable of executing a rapid charge algorithm for a rechargeable battery. The algorithm includes monitoring for a connection to an external power source and implementing a charging routine of a battery at a first charge rate and then at a second charge rate. The second charge rate is lower than the first charge rate. A temperature rise in the rechargeable battery due to the first charge rate has a negligible heat transfer effect on the fluid sample. The meter can also include a power switch for controlling current flow to a battery fuel gauge. The power switch is open when the meter enters into a sleep mode. The state of battery charge is determined after the meter exits the sleep mode.Type: ApplicationFiled: July 27, 2018Publication date: December 13, 2018Inventors: Igor Gofman, Jun Chen

Publication number: 20180177438Abstract: Embodiments herein provide detection of contamination at one or more contacts of a sensor system. The sensor system includes a sensor assembly and an electronics assembly communicatively coupled together by one or more contacts. The sensor assembly passes a sensor signal to the electronics assembly for further processing. The electronics assembly includes a detection contact for detecting contamination on or near one or more contacts of the sensor assembly and/or the electronics assembly. A switch selectively couples the detection contact to a bias voltage during a measurement mode and to a reference voltage during a detection mode, the reference voltage being different from the bias voltage. A method of contamination detection includes switching the electronics assembly between the measurement mode and the detection mode, and monitoring for a change in the output signal received by the electronics assembly.Type: ApplicationFiled: February 23, 2018Publication date: June 28, 2018Inventors: Igor Gofman, Mu Wu

Publication number: 20180018430Abstract: A portable data-management system may be easily employed with multiple processing devices by eliminating the need to pre-install additional programs, agents, device drivers, or other software components on the hosts. A portable storage device contains software for a data-management application, which receives and processes test data from a meter that measures an analyte. The portable device may employ an interface protocol that makes the portable device immediately compatible with different operating systems and hardware configurations. Once the portable device is connected to the host, the data-management application can be automatically launched. The convenience and portability of a data-management system may be enhanced by integrating advanced data processing and display features with the portable device. The users may access some advanced presentations of health data without having to launch the data-management application on a separate host.Type: ApplicationFiled: May 31, 2017Publication date: January 18, 2018Inventors: Darren Brown, Jun Chen, Igor Gofman, Steven B.

Patent number: 9673612Abstract: Reverse battery protection circuits for devices powered by batteries coupled in parallel can include both P-channel and N-channel MOSFETs. Each positive battery terminal connector of a battery-powered device can be coupled to a gate of an N-channel MOSFET or to both a gate of an N-channel MOSFET and a gate of a P-channel MOSFET. In some embodiments, each negative battery terminal connector of the device can be connected to a gate of a P-channel MOSFET. In the event of a reverse battery connection, one or more of the protection circuit's P-channel and N-channel MOSFETS can switch to a non-conductive state to isolate the device's load from an incorrectly installed battery and prevent the incorrectly installed battery and/or other parallel-coupled battery from prematurely discharging. Methods of protecting a load from a reverse battery connection are also provided, as are other aspects.Type: GrantFiled: March 11, 2016Date of Patent: June 6, 2017Assignee: ASCENSIA DIABETES CARE HOLDINGS AGInventor: Igor Gofman

Publication number: 20170074856Abstract: A test sensor (100) for determining an analyte concentration in a biological fluid comprises a strip including a fluid receiving area (128) and a port-insertion region (126). A first row of optically transparent (132) and non-transparent positions forms a calibration code pattern (130) disposed within a first area of the port-insertion region (126). A second row of optically transparent (142) and non-transparent positions forms a synchronization code pattern (140) disposed within a second area of the port-insertion region (126). The second area is different from the first area. The synchronization code pattern (140) corresponds to the calibration code pattern (130) such that the synchronization code pattern (140) provides synchronization of the serial calibration code pattern (130) during insertion of the port-insertion region (126) into the receiving port of the analyte meter.Type: ApplicationFiled: March 5, 2015Publication date: March 16, 2017Inventor: Igor Gofman

Publication number: 20170010882Abstract: An architecture allows individual system components to be developed and tested individually, i.e., as distinct modules, and to be subsequently combined through standardized electrical and communication interfaces. Any combination of these modules can be implemented to form different products that provide any number of functions, such as an integrated system for monitoring a health condition and/or delivering a medication. The architecture also provides an approach for dynamically updating the product and offering its users the latest generation of technology even after the users have already purchased the product. In particular, the embodiments employ the communication interfaces to also provide connection to a remote network that can update or upgrade the product's software when the product is out in the field.Type: ApplicationFiled: September 20, 2016Publication date: January 12, 2017Inventors: Steven Charlton, Jun Chen, Lin Chen, Qiang Fu, Igor Gofman, Steven B.
