Patent number: 10734841Abstract: A system and method for charging a chargeable device is provided. The system can include a wireless charger including a wireless power antenna and a wireless power transmitter coupled to the wireless power antenna and configured to generate a wireless charging field in at least one charging region. The wireless charging field includes a plurality of power signals. The wireless charger further includes a communication antenna and a transceiver coupled to the communication antenna and configured to communicate with the chargeable device via the communication antenna. The wireless charger further includes a controller configured to facilitate avoidance of cross connection of the chargeable device with the wireless charger and at least one other wireless charger in which the chargeable device receives power from the wireless power transmitter of the wireless charger while communicating with at least one other wireless charger.Type: GrantFiled: May 18, 2017Date of Patent: August 4, 2020Assignee: QUALCOMM IncorporatedInventors: William H. Von Novak, Edward Kallal

Patent number: 9583951Abstract: This disclosure provides systems, methods and apparatus for tuning a transmit coil for operation in a plurality of frequency bands. In one aspect, a method of wireless power transmission is provided. The method includes exciting a first part of a wireless power transmission system, via a wireless power transmitter. The method further includes detecting, in the presence of a non-charging object, a first change in a first parameter. The first parameter is indicative of a coupling between the non-charging object and the first part. The method further includes varying a characteristic of the wireless power transmission based on said first change.Type: GrantFiled: October 5, 2015Date of Patent: February 28, 2017Assignee: QUALCOMM INCORPORATEDInventors: William Henry Von Novak, Pavel Monat, Edward Kallal

Patent number: 9508487Abstract: This disclosure provides systems, methods, and apparatus for the limiting of voltage in wireless power receivers. In one aspect, an apparatus includes a power transfer component configured to receive power wirelessly from a transmitter. The apparatus further includes a circuit coupled to the power transfer component and configured to reduce a received voltage when activated. The apparatus further includes a controller configured to activate the circuit when the received voltage reaches a first threshold value and configured to deactivate the circuit when the received voltage reaches a second threshold value. The apparatus further includes an antenna configured to generate a signal to the transmitter that signals to the transmitter that the received voltage reached the first threshold value.Type: GrantFiled: September 18, 2012Date of Patent: November 29, 2016Assignee: Qualcomm IncorporatedInventors: William H. Von Novak, Joseph L. Archambault, Adam J. Wood, Edward Kallal, Ryan Tseng, Gabriel Isaac Mayo
