What's The Big Data?

Self-driving cars continued to make headlines recently. Google (Waymo) opened its early rider program in Phoenix, Arizona, to “hundreds” of residents “with diverse backgrounds and transportation needs.” Baidu open sourced its self-driving technology and said it’s on track to deliver self-driving cars by the end of 2020. And documents obtained by Business Insider and the Wall Street Journal revealed Apple has hired former NASA employees, robotics experts and ex-Tesla staffers to form part of its driverless car teams.

The news came during the National Safety Council’s Distracted Driving Awareness month. U.S. motor vehicle deaths in 2016 were estimated to be the highest in 9 years, with drivers saying they are comfortable speeding (64%), texting either manually or through voice controls (47%), driving while impaired by marijuana (13%) or driving after they feel they’ve had too much alcohol (10%).  A 3-month analysis of 3-million anonymous drivers, who made 570 million trips and…

Palestine-Israel Conflict

by Avi Goldreich, used by courtesy of Think-Israel.org

Translated from the Hebrew by Nurit Greenger.
Original Hebrew version can be read here.

The time machine is a sensation that nests in me when I am visiting Mr. Hobber old books store in Budapest, Hungary. Hobber learned to know my quirks and after the initial greeting and the glass of mineral water (Mr. Hobber is a vegan) he leads me down the stairs to the huge basement, to the Jewish “section.”

The Jewish section is a room full of antiquity books on subjects that Mr. Hobber sees to be Jewish. Among the books there are some that are not even worthy their leather binding. However, sometime, one can find there real culture treasure. Many of the books are Holy Books that may have been stolen from synagogues’ archives: Talmud, Bible, Mishnah, old Ashkenazi style Siddur, and others. Customarily, I open them…

The 3D printer we think more frequently in combination with PCBs is the DragonFly 2020 from Nano Dimension which works with different with all kinds of materials in addition to PCBs as they are a great 3D printing player in electronic space.

The Ultrasound Research group at Neurotechnology (http://www.neurotechnology.com) has proclaimed a new 3D printing method using ultrasonic manipulation which are totally hands off and non-contact tech behind it, permitting for the handling of parts and particles down to submillimeter range without causing damage to sensitive components. According to the project lead for Neurotechnology Ultrasound Research Group, Dr. Osvaldas Putkis, “Ultrasonic manipulation can handle a very large range of different materials, including metals, plastics and even liquids. Not only can it manipulate material particles, it can also handle components of various shapes. Other non-contact methods, like the ones based on magnetic or electrostatic forces, can’t offer such versatility”.

Since the work from the Ultrasound Research Group embodies a new technological application, Neurotechnology has filed a patent on their system. Neurotechnology describes ultrasonic manipulation as a “non-contact material handling method which uses ultrasonic waves to trap and move small particles and components.”  It is well known that ultrasonic manipulation of particles exploits the acoustic radiation force to deliver a contactless handling method for particles suspended in a fluid. In an ultrasonic standing wave field, the viscous torque induces the rotation of an object. Alongside the translation of particles due to the acoustic radiation force an additional controlled degree of rotation is obtainable. Consequently, there is a growing interest in spreading the field of application of ultrasonic particle manipulation to the deposition of micro and nanowires and for the assembly of micro objects.

Ultrasonic transducers are arranged in an array used to position electronic components in the creation of a PCB, utilizing a camera to detect accurate positioning. Continuing on with the hands-off theme, a laser solders the PCB components after their non-contact manipulation into placement. 3D printing and PCB manufacture are increasingly coming together, as advanced technologies benefit the creation of devices in electronics, including via 3D printed workstations for PCBs.

Even though their method works with all types of materials, we expect to see further applications beyond PCB assembly.

What's The Big Data?

cbinsights_race_for_aiCB Insights:

Nearly 140 private companies working to advance artificial intelligence technologies have been acquired since 2011, with over 40 acquisitions taking place in 2016 alone (as of 10/7/2016). Corporate giants like Google, IBM, Yahoo, Intel, Apple and Salesforce, are competing in the race to acquire private AI companies, with Samsung emerging as a new entrant this month with its acquisition of startup Viv Labs, which is developing a Siri-like AI assistant.
