Patent number: 10168227Abstract: A system and method for rapidly determining ambient temperature in a fluid-analyte meter. The meter includes a housing defining an interior space and an area for receiving a fluid sample. A processor and a first temperature sensor are disposed within the interior space of said the housing. A second temperature sensor is disposed on the housing. One or more processors are configured to determine a first temperature value from temperature data received from the first temperature sensor. The processor(s) are also configured to apply a variable current to a temperature-adjustment source such that the second temperature sensor is adjusted to a predetermined steady-state temperature value different from the first temperature value. The processor(s) are further configured to determine an ambient temperature of an exterior space of the housing based on the applied variable current, pre-determined steady-state temperature, and received first temperature values.Type: GrantFiled: November 21, 2017Date of Patent: January 1, 2019Assignee: ASCENSIA DIABETES CARE HOLDINGS AGInventor: Mu Wu

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: 20180106688Abstract: Methods and systems accurately determine an analyte concentration in a fluid sample. In an example embodiment, a receiving port receives a test sensor. The test sensor includes a fluid-receiving area for receiving a fluid sample. The fluid-receiving area contains a reagent that produces a measurable reaction with an analyte in the fluid sample. The test sensor has a test-sensor temperature and the reagent has a reagent temperature. A measurement system measures the reaction between the reagent and the analyte. A temperature-measuring system measures the test sensor temperature when the test sensor is received into the receiving port. A concentration of the analyte in the fluid sample is determined according to the measurement of the reaction and the measurement of the test sensor temperature. A diagnostic system determines an accuracy of the temperature-measuring system. The calculation of the analyte concentration may be adjusted according to the accuracy of temperature-measuring system.Type: ApplicationFiled: December 14, 2017Publication date: April 19, 2018Inventors: Narasinha Parasnis, Hoi-Cheong Steve Sun, 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.

Publication number: 20160170528Abstract: A capacitive touch panel with single sensing layer has a substrate. The substrate has the single sensing layer formed thereon. The sensing layer has multiple electrode sets. Each electrode set has multiple driving electrode rows and multiple receiving electrode rows arranged alternately. The multiple driving electrode rows of one electrode set have different driving electrodes, but different electrode sets have the same multiple driving electrode rows. The multiple receiving electrode rows of one electrode set are consisted of multiple same receiving electrodes, but different electrode sets have different receiving electrode rows. Therefore, using less contacts can also maintained the area and the solution so that the pins on the IC are also decreased. Thus, the volume of the IC is reduced and the packaging cost is also reduced.Type: ApplicationFiled: November 9, 2015Publication date: June 16, 2016Applicant: ELAN MICROELECTRONICS CORPORATIONInventors: Chia-Mu Wu, Ting-Hsuan Cheng

Publication number: 20160092019Abstract: A scanning method and device of a single layer capacitive touch panel has a self and mutual capacitive scanning procedures. The single layer capacitive touch panel has multiple electrode groups and shielding units respectively formed between the two corresponding adjacent electrode groups. When the self capacitive scanning procedure is executed, a first driving signal is outputted to each of the electrode groups and each of the shielding units. A self capacitive sensing signal of the driven electrode group is received after then. When the mutual capacitive scanning procedure is executed, a second driving signal is outputted to each of the electrode group and each of the shielding unit is connected to a ground. A mutual capacitive sensing signal from each of the driven electrode groups is received after then. Therefore, the self capacitance value of the self capacitive sensing signal is not increased greatly since the shielding units are not connected to the ground.Type: ApplicationFiled: September 9, 2015Publication date: March 31, 2016Applicant: ELAN MICROELECTRONICS CORPORATIONInventors: Jung-Shou Huang, Chia-Mu Wu
