20100165962 | METHOD OF CONTROLLING COMMUNICATION OF DATA PACKETS BASED ON DIFFERENT COMMUNICATION STANDARDS, A DUAL PLATFORM COMMUNICATION CONTROLLER AND A WIRELESS TRANSCEIVER - A dual platform communication controller, a method of controlling communication of data packets based on different communication standards and a wireless transceiver. In one embodiment, the dual platform communication controller includes: (1) a signal interpreter configured to recognize first data packets based on a first communication standard and second data packets based on a second communication standard and (2) a traffic manager coupled to the signal interpreter and configured to dynamically control communication of the second data packets including active second data packets and allocate bandwidth for communication of the first and second data packets. | 07-01-2010 |
20120214409 | Near field communication and frequency modulation coexistence concealment system and method - A system for determining a frequency modulated audio output of a mobile communication device during a near field communication transaction includes a transceiver providing a first frequency modulated audio signal. The device also is configured to determine when the near field communication transaction is occurring; a memory configured to store a replacement sound; and a selection circuit coupled with the transceiver and the memory to select the replacement sound when the near field communication transaction is occurring and select the first frequency modulated audio signal when the near field communication transaction is not occurring. There is also a signal path coupled with the selection circuit and configured to provide a second frequency modulated signal based on the selection circuit. In this way, the replacement sound is the audio output when the NFC transaction is occurring and the regular audio is output when the NFC transaction is not occurring. | 08-23-2012 |
20120214410 | Method and system for early termination of receive correlation window for Bluetooth communication - A system for terminating a receive correlation window of a receiving wireless device includes a radio frequency receiver configured to open a receive correlation window having a predetermined duration and an energy measurement circuit configured to measure a radio frequency energy level ambient to the wireless receiver. A comparator is included that is configured to determine, based on the measured radio frequency energy level, whether or not a signal is being transmitted from a nearby wireless device. The receiver is further configured to close the receive correlation window before the predetermined duration is reached in response to a determination by the comparator that no signal is being transmitted by a nearby device. If a signal is being transmitted, then the receive correlation window is allowed to proceed uninterrupted. | 08-23-2012 |
20130260687 | METHOD AND DEVICE TO SYNCHRONIZE BLUETOOTH AND LTE/WIMAX TRANSMISSIONS FOR ACHIEVING COEXISTENCE - A communication unit has BT and LTE transceivers, and a BT processor. The BT processor sets up a BT connection over the BT transceiver; performs a legacy command to synchronize BT transactions over the BT connection based on LTE frames in a LTE connection over the LTE transceiver, so that a BT network clock is synchronized to LTE frames. The legacy command is a role switch command that is used to set a BT alignment time of a switch point between Bluetooth master/slave packets to a LTE switch between transmit and receive; and is specified in a BT Core Specification 4.0 or earlier. The processor can determine an expected alignment time to align BT master and slave packets to transmit and receive in the LTE frame based on a start time of the LTE frame, and can indicate the expected alignment time in the legacy command. | 10-03-2013 |

20150091385 | POWER HARVEST ARCHITECTURE FOR NEAR FIELD COMMUNICATION DEVICES - A method of charging a power harvested supply in an electronic communication device, which can be an NFC (near field communication) device. The power harvested supply in the electronic communication device is charged without causing dV/V violation and avoids false wake up. An RF (radio frequency) field is received at the antenna of the electronic communication device. A differential voltage is generated from the RF field at a first tag pin and a second tag pin of the electronic communication device. A bandgap reference voltage and a reference current are generated in response to the differential voltage. A shunt current is generated in response to the differential voltage and the bandgap reference voltage. A bank of switching devices is activated if the shunt current is more than the reference current. | 04-02-2015 |
20150208451 | Access Point Discoverability in Multi-Role Multi-Channel Devices - Systems and methods for improved access point discoverability in multi-role multi-channel devices are described. When the multi-role multi-channel device leaves an AP role and then later returns to the AP role, such as when operating in another role, the multi-role multi-channel device sends a unicast probe response to the stations in a predetermined list. The unicast probe response is transmitted even without receiving a corresponding probe request. If one of the stations on the list is in the area and would like to connect to the AP role, it can complete the connection process using information in the response message. | 07-23-2015 |
