- Inductive Touch Buttons for HMIsPDF, 315 Kb, Archivo publicado: enero 9, 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 Mb, Archivo publicado: feb 2, 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 Kb, Archivo publicado: feb 28, 2017
- Inductive Touch - Configuring LDC2114 Touch-Button SensitivityPDF, 771 Kb, Archivo publicado: marzo 16, 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 Kb, Archivo publicado: feb 22, 2017
