Despite wide use of “soft” on/off switching, the traditional electromechanical switch is still often required or preferred and is available in countless versions. Let’s look at some available switch styles. 1) The knife switch It doesn’t get simpler than the knife switch. The first and simplest switch is the knife switch (Figure 1). This style […]
FAQ
What are the parameters of electromechanical of/off switches?
Despite wide use of “soft” on/off switching, the traditional electromechanical switch is still often required or preferred and is available in countless versions. As with all components, there are some top-tier parameters as well as many secondary ones, and some of those secondary ones may be very important in a specific application. As expected, the […]
What are the symbols for electromechanical on/off switches?
Despite wide use of “soft” on/off switching, the traditional electromechanical switch is still often required or preferred and is available in countless versions. Switches are represented by their schematic diagram symbols, which correspond to the number and arrangement of their contacts. Schematic symbols tell part of the story In an electromechanical hardwired on/off switch, the […]
What is the role of electromechanical on/off switches?
Despite wide use of “soft” on/off switching, the traditional electromechanical switch is still often required or preferred and is available in countless versions. Switches are an integral, very necessary part of most electronic products. They have two broad roles: As power switches which, as their name indicates, cut the flow of power from the source, […]
What is sensor fusion?
by Charles Pao, senior marketing specialist, CEVA Motion sensing devices are all around us and in several of the electronics that we use daily. Motion sensors are in earbuds – noticing taps to change songs or pausing music when we take them out of our ears. They’re used for head tracking in virtual reality (VR) […]
Creating unique devices with haptic touch technology
By Nedko Ivanov, Aito Consumer technology products are becoming increasingly difficult for designers and manufacturers to differentiate. Laptops, in particular, are all of a similar size and shape and offer the same functionality. Clamshell laptops typically combine the same three features – a display, a keyboard, and a touchpad – with few aspects that distinguish […]
What are different types of biometric sensors?
The term “Biometrics” is derived from “bio’” which means life, and “metrics”, which means measurement. Biometrics is developing for use in various technologies, including the unique identification and recognition of people. The technology at its current juncture is widely used in security and surveillance systems. Biometrics also has the possibility of converging with other technologies […]
The automotive Tire Pressure Monitoring System, Part 4: Issues
Sensor-based monitoring systems for tire pressure can warn of potential problems, but there’s much more to the story than just a pressure-measurement system. The TPMS adds a highly specific safety-related feature to cars. However, as with many presumably good ideas, the “devil is in the details”, and that’s especially true for the TPMS. There are […]
The automotive Tire Pressure Monitoring System, Part 3: Implementation
Sensor-based monitoring systems for tire pressure can warn of potential problems, but there’s much more to the story than just a pressure-measurement system. Once the decision was made to use the direct measurement technique, IC vendors developed the needed components and equally important packaging. A TMPS requires a significant amount of analog, digital, and RF […]
The automotive Tire Pressure Monitoring System, Part 2: Perspectives
Sensor-based monitoring systems for tire pressure can warn of potential problems, but there’s much more to the story than just a pressure-measurement system. During the comments phase before the formal safety mandate was published per the legislative direction, the automotive-related communities had differing views on the need or wisdom of the electronic TPMS: The auto […]
