Abstract: A smartwatch with a pressure sensing function is disclosed. The smartwatch includes a watch body and a wristband. The watch body includes a front case, a touchscreen, a bottom case, at least one processor, and a pressure sensor that is disposed on the bottom case. In some instances, when pressure is applied to a touchscreen, the watch body transfers the pressure to a contact surface, and the contact surface exerts a reacting force to the pressure sensor on the bottom case. In some instances, the at least one processor obtains position coordinates from the touchscreen and obtains a pressure value from the pressure sensor.

Abstract: Unique and improved chromizing processes are disclosed. The processes involve forming localized chromizing coatings onto selected regions of a substrate. The chromium diffusion coatings are locally applied to selected regions of substrates in a controlled manner, in comparison to conventional chromizing processes, and further in a manner that produces less material waste and does not require diffusion-stop-off masking. Prior to or after a localized slurry chromizing process of the present invention, a layer of a platinum-group-metal (PGM) is applied to produce a PGM-modified chromium diffusion coating onto selected regions of a substrate. A second coating can be selectively applied onto other regions of the substrate.
