The design of display electronics and data delivery order that allows a VR headset to limit human detectable artifacts in a overdriven display technology.

This shield can patent extension details some unique design features the Surface Pro team used to solve the issues around EMC and WiFi radio desense using clips, foam, and partial frames to realize the thin designs of the Microsoft Surface product line.

The ratcheting cam mechanism in the Microsoft Surface Book products that allows a muscle wire to cycle through passive conditions of locked and unlocked. Extension of first patent.

Method for PC or other consumer electronics to maintain power states between a device and its accessory and transfer energy based on the host and accessory power levels. Extension of original patent.

This patent describes the power contract negotiation Surface Pro3/4/Surface Book Pro negotiate with their accessories plugged into the Surface Connect connector and the Surface docking connector keyboard/ secondary battery interface.

This patent application details yet another extension to that original patent of the Microsoft Surface Connect Docking and power connectors. Pinout for docking, and power shown here.

This patent covers the connector that is an extension of the Surface Pro line of docking connectors to also act as the GPU connections between the GPU keyboard base and the tablet top of the Surface Book product. It includes the original Surface connector in its design to allow charging using the existing ecosystem when the top is separated and acting alone as a tablet. This was the last thing I designed before leaving Microsoft.

Method for PC or other consumer electronics to maintain power states between a device and its accessory and transfer energy based on the host and accessory power levels.

This patent application details yet another extension to that original patent of the Microsoft Surface Connect Docking and power connectors. Reversibility described here.

This is an extension of a previous patent on MULTI-DROP SERIAL BUS WITH LOCATION DETECTION AND METHOD. It secures the feature of the bus communication structure that ensures a location detection can occur on the bus.

This patent describes the method in which the Surface Pro3/4/Surface Book Pro power and data connector negotiates its signal paths and data configurations for data type and reversibility. This is what allows the surface dock to be connected in either orientation.

Method of a system like a tablet PC to sense with its microphone the amplitude of the CPU fan noise to quiet it below a required limit for performance or aesthetic sound quality

Covering the methods we have developed for Microsoft related to communication of a host PC with its power supplies inexpensively

This is the second filing for the Surface Pro3/4/Surface Book Pro power and data connectors. This connector is reversible, can provide power, and 8 pairs of high speed serial data (DisplayPort/HDMI/USB3/etc...). In use in the Surface Pro Dock: http://www.microsoftstore.com/store/msusa/en_US/pdp/productID.325725200

Method to linearize a pressure sensor to improve its sensitivity

Invention originally developed to assist HP Inkjet Printer customers when they install their inkjet cartridges in the wrong slots. This allows detection of where a bus communicating device that is pluggable was installed on the communication bus without adding other wires to the system. I2C is an ideal bus for this since it uses a pull-up on the data line that is used as a voltage divider indicating the location ID.The customer could then be presented with the map showing the error and how to… Show more

I2C is an ideal bus for this since it uses a pull-up on the data line that is used as a voltage divider indicating the location ID.The customer could then be presented with the map showing the error and how to correct it (not in the patent). This patent allowed simpler cartridge electronics, saving millions of dollars and counting. Show less

A system lockout service that is implemented to disable one or more of the capacitive touch controls based on user interaction with the touch-screen display of a system like a tablet PC or the like.

Keypad multiplexing method which takes advantage of LED brightness advances to mux LEDs and switches in the same matrix vastly reducing interconnect for a keypad interface. This interface was initially implemented in a printer line using standard GPIO on 2ms timer, then was integrated into all future printer ASICs as standard hardware. Over 10M+ savings in 2006 estimates.

Interesting ways to prevent ESD from damaging high access rate inkjet cartridge chutes during ink change. Mostly involves using flex circuit geometries to intercept charge.

This patent application details the of the Surface Pro 1, 2, and 3 docking connectors. These are the connectors that are the magnetic hold connectors for the Surface keyboards and also what became the Surface Pro 3 magnetic power and docking connector.
