3D Systems Corporation (DDD) on Sept. 20, 2016 announced the launch of Jaw in a Day®, the latest addition to its VSP® (Virtual Surgical Planning) Reconstruction product line. Enabled by 3D Systems’ healthcare expertise and proprietary digital-to-physical workflow, this patient-specific process enables surgeons to perform a full jaw reconstruction in a single surgery. This groundbreaking capability could spare patients from months of costly, painful and disruptive medical treatment.

Traditional dental rehabilitation requires multiple surgeries and persistent care over a 6-12 month period. This pattern of procedures often results in patients missing teeth, which introduces a variety of adverse aesthetic, functional, and psychological effects to the patient. This can in turn interfere with patients’ working and social lives throughout the course of treatment.

Jaw in a Day is a single surgery jaw and dental reconstruction enabled via 3D Systems’ VSP Reconstruction service. Surgeons work with 3D Systems engineers who utilize state-of the-art digital CAD/CAM technology to create a personalized surgical plan and design patient-specific surgical guides, models and instruments. These devices are then 3D printed and sterilized for reference and use during the unique procedure. Immediate placement of a provisional dental prosthesis eliminates the need for multiple surgeries, resulting in a complete dental reconstruction months before traditional treatment options.

Shares of QUALCOMM, Inc. (NASDAQ:QCOM) ended Friday session in green amid volatile trading. The shares closed up +1.05 points or 1.56% at $68.50 with 34,879,502 shares getting traded. Post opening the session at $68.40, the shares hit an intraday low of $68.15 and an intraday high of $70.40 and the price vacillated in this range throughout the day. The company has a market cap of $102.52 billion and the numbers of outstanding shares have been calculated to be 1.47 billion shares.

QUALCOMM, Inc. (QCOM) on Sept. 28, 2016 announced that its subsidiary, Qualcomm Technologies, Inc. (QTI), and SK Telecom (CEO Dong-hyun Jang, www.sktelecom.com) announced the first over-the-air technology demonstration of eLAA (Enhanced Licensed Assisted Access) and LAA (Licensed Assisted Access) that utilizes both licensed and unlicensed spectrum at SK Telecom’s Corporate R&D Center in Bundang, Korea.

eLAA technology increases data speeds in both uplink and downlink by aggregating licensed and unlicensed spectrum to create a wider data pipe in both directions. eLAA is an evolution of LAA, which used the unlicensed spectrum to boost the data speed in the downlink direction only.

The demo uses 2.6GHz licensed spectrum and 5GHz unlicensed spectrum. When evaluating coexistence, a baseline was first established using only Wi-Fi users, of which some were then switched from Wi-Fi to LAA/eLAA while others remained on Wi-Fi. The trial demonstrated that the users that remained on Wi-Fi were unaffected by those that switched to LAA/eLAA. This effectively demonstrates that LAA/eLAA shares the unlicensed spectrum fairly with Wi-Fi. The sharing mechanism used by LAA/eLAA is called listen-before-talk (LBT). As for performance, LAA and eLAA were shown in multiple test cases to achieve 2X capacity in 5 GHz than the Wi-Fi only baseline.

In June 2015, SK Telecom launched “Band LTE Wi-Fi” service based on Multi-Path Transmission Control Protocol (MPTCP) technology that combines LTE and Wi-Fi traffic to enable downlink rates up to 1.17Gbps. This means that SK Telecom can now choose from two available technologies to combine unlicensed spectrum with existing LTE spectrum, eLAA and MPTCP.
