MATERIALS:Lee Spring® introduces LeePTM Plastic Composite Springs, a revolutionary breakthrough in spring technology. LeeP is Lee Spring’s answer to increased customer requests for springs that combine the strength of metal with the special attributes of high performing engineered thermoplastics. After years of extensive engineering design and materials research by their expert technical team, Lee Spring developed these unique compression springs. LeeP springs are fabricated in distinctive formulations of Ultem* PEI resins. The company says it selected Ultem resin as the material of choice for LeeP because it meets or exceeds the criteria it set forth for developing this line. Ultem resin is produced by SABIC Innovative Plastics, a leader in engineered thermoplastic material solutions.
LeeP Plastic Composite Springs are stocked in a variety of standard sizes, each available in a “rainbow” of strengths formulated from different Ultem resins. The six increasing strengths are easily identifiable by distinct colors: red, orange, yellow, green, blue and violet, with violet being the strongest. In addition to its initial LeeP Stock Compression Spring offering, Lee Spring has developed the advanced technology to provide Custom LeeP Springs to meet customers’ most exacting requirements.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
