Patent number: 9020425Abstract: A NFC communications enabled device has a data store to store data, an inductive coupler to couple inductively with the magnetic field of a radio frequency signal and a signal supplier to supply a radio frequency signal to the inductive coupler. A modulator modulates a radio frequency signal in accordance with data and a demodulator extracts data from a modulated radio frequency signal inductively coupled to the coupler. A controller enables the NFC communications enabled device both to initiate near field radio frequency communication with another near field RF communicator and to respond to near field radio frequency communication initiated by another near field RF communicator. The inductive coupler has an antenna and a variable impedance element. The controller is configured to control the variable impedance element to control a magnetic field strength associated with a radio frequency signal supplied by the signal supplier.Type: GrantFiled: July 25, 2012Date of Patent: April 28, 2015Assignee: Broadcom Europe LimitedInventor: Peter Symons

Patent number: 8306583Abstract: A variable configuration apparatus has components or sub-systems. At least some components (200 and 201) have mechanical coupling elements (101 and 102 and 103) that enable the configuration of the apparatus to be varied by changing at least one of the relative orientation and position of those components or subsystems. These mechanical coupling elements (101 and 102 and 103) incorporate wireless signal coupling elements (205 and 206) that cooperate to provide a wireless coupling which enables wireless coupling between the components. The wireless coupling may be used to transfer at least one of data and power between the components. The wireless signal coupling elements may be capacitive coupling elements that provide capacitive coupling between the components or sub-systems. In an example, the apparatus is a video camera and one component or sub-system is a display screen (201) and another component or sub-system is the main body (200) of the video camera (200).Type: GrantFiled: May 18, 2010Date of Patent: November 6, 2012Assignee: J.M.
