SLI: Sensing Without Touching

MEMS is revolutionizing technology, causing microminiaturization and increasing the precision of conventional solutions. Ubiquitous MEMS applications are emerging as the next most promising frontier by removing the need for touch in structured light illumination or SLI. DLPs or digital light processors from Texas Instruments contain millions of mirrors. TI is pioneering SLI that works by projecting moving stripes of light onto objects. It then measures the deformities in the reflected patterns Read more [...]

Why are Inductance-to-Digital Converters Useful?

Inductive sensing is bringing a revolution in the technical world. Inductive sensing offers capabilities for measuring position, motion and or composition of a conductive or metal target, with a contact-less, magnet-free sensing technology. In addition, inductive sensing can help to detect twist, compression or extension of a spring. Now, LDC or Inductance-to-Digital converters from Texas Instruments, such as the LDC1614, is helping to utilize springs and coils as inductive sensors that can deliver Read more [...]

Efficient Control of Motors at Low Speeds

When a motor is operating at high electrical frequency or high mechanical speed, the back EMF signal generated by the rotating rotor presents an efficient feedback technique for a sensor less motor control. However, generation of the back EMF requires a minimum frequency and that makes it difficult to control motors running at low speeds. The process of continuously estimating the rotor flux angle at zero and very low speeds, together with stably moving between low-speed and high-speed estimators Read more [...]
