Humidity can be measured by various sensors, but sensors SHT from company Sensirion add many benefits moreover. To be exact, a word „sensors“ is not a suitable expression in this case. As SHT series sensors contain on one chip humidity and temperature sensor, precise supply, low noise linear amplifier, AD converter and a serial interface, […]

Analysts have noted Apple’s comments on the importance of new services in its plans and an integrated fingerprint sensor capability in a mobile phone could prove the key enabler – literally opening the door to a new class of authentication-based apps and services – likely leveraging Apple’s move into automotive markets that Apple CEO Tim […]

Michael Lewis’s bestselling book “Flash Boys” describes how some brokers, engaging in high frequency trading, exploit fast telecommunications to gain fraction-of-a-second advantage in the buying and selling of stocks. But you don’t need to have billions of dollars riding on this-second securities transactions to appreciate the importance of fast signal processing

Description The LTC®2057 is a high voltage, low noise, zero-drift operational amplifier that offers precision DC performance over a wide supply range of 4.75V to 36V or 4.75V to 60V for the LTC2057HV. Offset voltage and 1/f noise are suppressed, allowing this amplifier to achieve a maximum offset voltage of 4μV and a DC to […]

A new genetic study has revealed that populations of humpback whales in the oceans of the North Pacific, North Atlantic and Southern Hemisphere are much more distinct from each other than previously thought, and should be recognised as separate subspecies. Understanding how connected these populations are has important implications for the recovery of these charismatic animals that were once devastated by hunting.

(Phys.org) —A study by a pair of researchers with the University of Maine suggests that the northern coast of Peru may have been altered due to population shifts as a result of the Spanish conquest in the 1500’s. In their paper published in Proceedings of the National Academy of Sciences, Daniel Belknap and Daniel Sandweiss describe a field study they conducted in the area that suggested that Inca living on the coast prior to the Spanish conquest, may have inadvertently been supporting the existence of sand ridges by discarding mollusk shells.

Kyocera has developed an ultra-thin, lightweight audio device, dubbed the Smart Sonic Sound, based on the company’s fine ceramic technology. The 1mm-thin speaker uses a piezoelectric actuator combined with a special film to create a piezo film speaker, enabling the manufacture of very thin TVs, PCs and tablets with improved audio quality. The device’s low […]

(Phys.org) —After eluding scientists for nearly 80 years, the Clarion nightsnake (Hypsiglena ochrorhyncha unaocularus), a nocturnal reptilian species that was initially discovered in the first half of the 19th century and then struck from the scientific record, was rediscovered by National Museum of Natural History researcher Daniel Mulcahy. The new snake species is found exclusively on the Mexican island of Clarion and could have remained unknown to science if not for the team’s efforts to solve the case surrounding its disappearance.

Semiconductor curve tracers were frequently used in analog circuit designs many decades ago, at a time when discrete semiconductor devices were in dominance and ICs were scarce. While curve tracers are no longer widely used nowadays due to the ubiquity of digital circuitry and computer aided designs, they are still quite popular in the educational […]

(Phys.org) —Mainstream talk about the Internet of Things continues unabated, as more people become familiar with the concept of having connected devices in their homes and the communities. The talk is about smart devices connected to the Internet and to each other, from meters to washing machines to fitness-tracking wearables, to kitchen devices, to far more gadgets that go “on” and “off.” Depending on which analysts you talk to, forecasts range from estimates of seeing 25 billion to 50 billion connected devices worldwide by 2020, but IoT pundits also point to the challenges ahead in cost and energy use.
