Praveen Subramani design + technology + cities

Apple

During Summers 2009 and 2010, I interned at Apple, Inc. with the Platform Architecture Engineering Team, a division of Mac Hardware Engineering. My primary responsibilities involved the design and fabrication of electrical systems for new technology hardware prototypes. I designed active component printed circuit boards including component selection and integration, layout, fabrication, and testing. I successfully produced fully functional prototypes which I presented to senior-level executives at the end of my internship. Though confidentiality agreements prevent me from discussing the specific projects I was involved with, I worked on projects related to novel, hardware-based input devices including the capacitance-sensing technology behind the Apple Magic Mouse (pictured above).

The work from my summer internships contributed significantly to the filing and issuing of five US patents [US PTO link], on which I am listed as a co-inventor:

  • [1] 20120050211 CONCURRENT SIGNAL DETECTION FOR TOUCH AND HOVER SENSING
  • [2] 20120050210 TOUCH AND HOVER SIGNAL DRIFT COMPENSATION
  • [3] 20120050209 TOUCH AND HOVER SENSOR COMPENSATION
  • [4] 20120050181 SIGNAL PROCESSING FOR TOUCH AND HOVER SENSING DISPLAY DEVICE
  • [5] 20120050180 TOUCH AND HOVER SWITCHING
