Capacitive sensing is all about the ability to measure the capacitance, or more often the change in capacitance, between two or more electrodes. As a technique it is frequently employed to detect proximity or position but can also be used to measure humidity, fluid level and acceleration. Because capacitive sensing supports such a diverse range of applications, solutions are found in many different markets — from industrial, automotive and medical through to consumer. And as more and more electronic products are being designed with touchpads and touchscreens we are seeing an explosion in the use of capacitive sensing technology to provide the vital human machine interface (HMI).
Distec launched their new ArtistaGUI human machine interface (HMI) controller. The ArtistaGUI graphic controller enables simple machine controls with a graphical user interface and touchscreen without substantial modifications to the control electronics. Programming of the GUI is carried out with a WYSIWYG Interface Designer and the QT-Quick scripting language. The communication protocol is the robust and in-field proven Modbus-RTU.
WIN Enterprises introduced the PL-80270 touch panel computer. The touch panel PC provides graphics-based visualization of specialized computer processes such as programmable automation controllers (PAC), programmable logic controllers (PLC), and distributed control system (DCS). The fanless open frame PL-80270 features a smart card reader, three RS-232 COM, two photo-couple inputs, two dry contact relay output, and five GPIO. The WIN PL-80270 is available now. Prices start at $112 in quantities above 20 units.
DuroPC Industrial Computers announced the DuroPC PAN221, PAN148, PAN150, PAN219, and PAN220 Human Machine Interface (HMI) Panel PCs. The industrial grade Panel PC line features Intel Atom processors, fanless design, touch screen, Wonderware InTouch CE v10.1 HMI software, high-brightness LED backlit LCD display, and long life. The HMI panel computers range in size from 5.7″ to 17″. The new DuroPC supports the Windows 7 operating system and can be integrated directly into PCA, PLC, DCS, factory SCADA systems, operator terminals and automation applications. The are ideal for factory and industrial automation applications.
We’ve all seen the iPhone. The phrase game changing gets thrown around a lot, but this is one instance where it’s truly applicable. It has put the Human Machine Interface (HMI) on the top of the list of major considerations in product marketing and development.
Can you imagine a world where the iPhone costs $1000 or where the animations from screen to screen are jerky and halting? Either extreme could have extinguished this user interface torchbearer before anyone saw the light.
Product designers are faced with these types of dilemmas every day. Experienced designers understand that there are some choices that are critical to the success of the product — and they often must be made at the project start, when the least is known about requirements.
VIA Technologies introduced the 6.5 inch VIA VIPRO VP7806 and 15 inch VIA VIPRO VP7815 fanless touch screen panel PCs. The VIA VIPRO devices feature Em-ITX form factor, an integrated two megapixel autofocus IP camera, microphone, and speakers. The IP65 compliant LED backlit panels can withstand temperatures of -200 °C to 600 °C. The VIA VIPRO VP7806 and VIPRO VP7815 are based on the VIA ART 3000 embedded box system. The VIA VIPRO VP7806 and VIPRO VP7815 are ideal for hospital patient terminals, home and building automation, and multimedia security systems.
