Publication number: 20230327796Abstract: A microphone jammer includes an ultrasonic transducer for emitting an ultrasonic jamming signal to jam a microphone of an external electronic device. The apparatus includes a sound chamber that is shaped to direct the ultrasonic jamming signal towards an area for placement of an external electronic device that includes the microphone. The apparatus may include a base and a top portion connected to the base, with the ultrasonic transducer being in the top portion and the sound chamber being shaped to direct the ultrasonic jamming signal towards the base.Type: ApplicationFiled: June 2, 2021Publication date: October 12, 2023Inventors: David John NICKEL, Bruce John CLELAND, Evan Bradley Osborne MCDOUGALL, Kerry CHIN, Shawn STEVENSON, Morgan GILBERT

Patent number: 9031604Abstract: Certain aspects of a method and system for providing wireless communication may include a single integrated circuit (IC) that handles communication for at least a Bluetooth (BT) connection and a Wireless Local Area Network (WLAN) connection by controlling transmission of acknowledgement signals based on a measured voice quality for one or both of the BT connection and the WLAN connection. The transmission of the acknowledgement signals communicated from the mobile station to an access point may be controlled. A BT priority signal may be asserted if data to be transmitted comprises high quality voice (HV3) data. The transmission of the acknowledgement signals may be controlled by raising a priority of an asserted WLAN priority signal higher than a priority of the asserted BT priority signal. The voice data may be transmitted via high quality voice (HV3) frames over the BT connection based on the asserted WLAN priority signal.Type: GrantFiled: March 23, 2006Date of Patent: May 12, 2015Assignee: Broadcom CorporationInventors: Prasanna Desai, Shawn Stevenson

Patent number: 8588073Abstract: A voice queue includes a primary queue and a secondary queue. The secondary queue is operable to store voice packets and generate timestamps for the voice packets. The primary queue is operable to receive the voice packets from the secondary queue, store the timestamps for the voice packets, and store sequence numbers for the voice packets.Type: GrantFiled: May 9, 2012Date of Patent: November 19, 2013Assignee: Broadcom CorporationInventors: Henry Li, David M. Enns, Jordan J. Nicol, Kenny C. Kwan, Ross Mitchell, Wilf LeBlanc, Ken Unger, John Payton, Shawn Stevenson, Bill Boora, Onur Tackin

Patent number: 8515054Abstract: A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier. The signal processing system includes a voice exchange, a data exchange and a call discriminator. The voice exchange is capable of exchanging voice signals between a switched circuit network and a packet based network. The signal processing system also includes a data exchange capable of exchanging data signals modulated by a voiceband carrier on the switched circuit network with unmodulated data signal packets on the packet based network. The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.Type: GrantFiled: August 10, 2010Date of Patent: August 20, 2013Assignee: Broadcom CorporationInventors: Wilf LeBlanc, Shawn Stevenson, Bill Boora
