20090147829 | METHOD AND SYSTEM FOR DYNAMICALLY CHANGING AUDIO STREAM BIT RATE BASED ON CONDITION OF A BLUETOOTH.RTM. CONNECTION - A method for communication is disclosed and may include dynamically changing the bit-rate of an audio and/or video stream communicated over a Bluetooth connection based on conditions of the Bluetooth connection. A rate at which corresponding audio and/or video samples, for said audio and/or video stream, are encoded for communication via the Bluetooth connection, may be based on Bluetooth piconet event information. The bit-rate of the audio and/or video stream may be dynamically adjusting based on bandwidth of the Bluetooth connection. The bit-rate of the audio and/or video stream may be dynamically increased based on bandwidth of the Bluetooth connection. The bit-rate of the audio and/or video stream may be dynamically decreased based on bandwidth of the Bluetooth connection. The audio and/or video samples may be encoded utilizing a variable bit rate. | 06-11-2009 |
20100020729 | METHOD AND SYSTEM FOR HALF DUPLEX AUDIO IN A BLUETOOTH STEREO HEADSET - Aspects of a method and system for half duplex audio in a Bluetooth stereo headset are provided. A service type and/or service activity levels may be detected over a link in a duplex communication system. The link may be dynamically changed according to the detected service activity levels in both direction of the link. The duplex communication system may be a communication system capable of supporting duplex communication, for example, a Bluetooth system, or a 3GPP system, or a WiMAX system, or a WiFi system. The link may be a synchronous connection-oriented (SCO) link such as the SCO link. The duplex communication system may be enabled to determine an operating mode, whether symmetric or asymmetric, based said detected service type and/or said detected service activity levels over the SCO link. In this regard, the SCO link may be dynamically switched from symmetric to asymmetric operating mode and vice versa. | 01-28-2010 |
20110021143 | METHOD AND SYSTEM FOR REDUCING BURDEN ON A BLUETOOTH LOW POWER END-POINT DEVICE - A relay host wireless device is paired with a target host wireless device over a secure link. The relay host wireless device is operable to acquire link security information, which is associated with a link between the target host wireless device and a wireless end-point device, from the target host wireless device. The relay host wireless device is enabled to establish a link with the target host wireless device by faking its identity as an assumed identity of the target host wireless device. The acquired link security information is applied to the established link. The relay host wireless device is enabled to relay content between the target host wireless device and the wireless end-point device via the established fake link using said assumed identity of the target host wireless device and the secure link between the relay host wireless device and the target host wireless device, successively. | 01-27-2011 |
20110319020 | METHOD AND SYSTEM FOR MULTI-STAGE DEVICE FILTERING IN A BLUETOOTH LOW ENERGY DEVICE - A Bluetooth low energy (BLE) device receives advertising packets from an advertising BLE device. The BLE device filters the received advertising packets utilizing hardware to search for the advertiser. If the advertiser is not found by the hardware, the packet filtering continues utilizing firmware. Device identity information, comprising non-private and/or private device identities, of preferred BLE devices is partitioned to form a different white list for the hardware, firmware, and host, respectively, to concurrently support privacy and white listing. If the advertiser is found by the hardware, the hardware sends a response to the advertiser following a successful CRC check performed in the hardware. If the advertiser is found by the firmware, the device identity information of the advertiser is inserted in the white list for the hardware. The host may be awakened based on the device configuration and/or attribute type information of the received advertising packets. | 12-29-2011 |
20130331029 | Near Field Communication Application Identification Routing In Card Emulation - A near field communications (NFC) device is disclosed that interacts with other NFC devices to exchange information and/or the data. The NFC device can include a plurality of secure elements each configured to store one or more card emulation instances. Each card emulation instance is associated with an application identification (AID) and a priority value. The NFC device can route communications between another NFC device and plurality of secure elements based on each card emulation instance's associated AID and priority value. | 12-12-2013 |

20140087655 | SYSTEMS AND METHODS FOR DETERMINING WHETHER A COMPANION COMMUNICATION DEVICE IS BEYOND A PROXIMITY OF A PRIMARY COMMUNICATION DEVICE - Systems and methods for determining whether a companion communication device is beyond a proximity of a primary communication device are provided. In some aspects, a system includes an analysis module configured to determine whether a wireless transaction between the primary communication device and the companion communication device is at a conclusion. The system also includes a communications module configured to emit a sensing signal based on the determination of whether the transaction is at the conclusion. The sensing signal is insufficient to elicit a response from the companion communication device. The system also includes a detection module configured to detect a present parameter associated with the emitted sensing signal. The analysis module is configured to determine a parameter change between the present parameter and a reference parameter, and to determine whether the companion communication device is beyond the proximity of the primary communication device based on the parameter change. | 03-27-2014 |
