The two firms each revealed their patents, counted among the 6,746 patents that were issued this week by the US Patent office. LinkedIn’s patent involves a new technique of pairing multiple devices. User devices have to be placed near each other and then the user can perform a simple gesture on the screen. The gesture should be repeated on multiple devices for the feature to work the way it was intended. When pairing is achieved, users can then go ahead and share data including business cards.

Google’s patent involves the use of radar recognition to allow for better searches. The techniques listed in the patent allow the enhanced computer-aided searches to use physical information and information provided by radar signals. This allows final search results to be more efficient.

Say for example a user is watching TV and sees an exciting vehicle he or she wants to know more about. The user can just point a device at the TV and ask what type of vehicle that was, and should receive results about the vehicle. The radar field used in this patent may come from a smartphone or other devices that are nearby.

Another patent released by Google recently involves a humanoid robot that was made by Google’s robotics division, Boston Dynamics.

Ford Motor Company (NYSE:F) also filed a patent that is interestingly not related to motor vehicles. The patent is for a support system for bicycles that eliminates the need for riders to support themselves when on a standstill by putting their feet down. The support system allows the rider’s feet to remain on the pedals even at stops.

Walt Disney Co (NYSE:DIS) also received a patent for making custom surface reflections for 3D printed items. One of the flaws of 3D printing is that 3D printing cannot duplicate reflective properties. The technique allows the printing of a reflective outer surface.
