- Inductive Touch Buttons for HMIsPDF, 315 Кб, Файл опубликован: 9 янв 2017
Consumer electronic device designs need to beattractive and reliable to be successful. However, mostdevices still rely on mechanical buttons which oftenemploy moving parts, gaskets, and cutouts leading tolong term reliability issues, increased costs, andinferior immunity to environmental factors. Inductivetouch buttons on the other hand enable aestheticallyattractive, gasket less, an - LDC2112/LDC2114 Inductive Touch System Design GuidePDF, 3.0 Мб, Файл опубликован: 2 фев 2017
The Inductive Touch System Design Guide presents an overview of the typical sensor mechanicalstructure and sensor electrical design for human machine interface (HMI) button applications. Themechanical design chapter discusses several factors that impact button sensitivity, including metalselection, sensor geometry, sensitivity dependence on target-to-coil distance, and mechanical isolation - Inductive Touch Buttons for WearablesPDF, 386 Кб, Файл опубликован: 28 фев 2017
- Inductive Touch - Configuring LDC2114 Touch-Button SensitivityPDF, 771 Кб, Файл опубликован: 16 мар 2017
Erroneous or unintended button presses can result in a frustrating user experience in a human machine interface (HMI). Capacitive touch buttons trigger anytime a grounded object is brought close to the button; this can often cause false or erroneous button presses. One advantage mechanical buttons have over capacitive touch buttons is that a certain amount of force must be applied on the buttons f - EMI Considerations for Inductive SensingPDF, 151 Кб, Файл опубликован: 22 фев 2017
This application note explains various EMI reduction techniques to help improve EMI performance for TI'sInductance-to-Digital Converters (LDC). Each section details a general technique with references to otheruseful online documents. A list of relevant EMI reduction techniques is provided for specific devices withinthe LDC family of products. - LDC1xxx LDC Target Design (Rev. A)PDF, 907 Кб, Версия: A, Файл опубликован: 9 май 2017
Texas Instruments’ Inductive-to-Digital Converter (LDC) technology can accurately measure with a wide variety of target sizes, shapes, and material composition. There are several target design guidelines to maximize the effectiveness of an LDC measurement system. This application note covers the relevant factors of target design that affect inductive sensing, and provides guide
