Signaling for wireless communications
A communication system, such as a wireless CDMA system, detects markers with fewer errors by having field units transmit the markers at different power levels (e.g., 9 dB for one marker and 11 dB for another marker).

Use of face and motion detection for best view framing in video conference endpoint
A video conference endpoint detects faces at associated face positions in video frames capturing a scene. The endpoint frames the video frames to a view of the scene encompassing all of the detected faces. The endpoint detects that a previously detected face is no longer detected. In response, a timeout period is started and independently of detecting faces, motion is detected across the view. It is determined if any detected motion (i) coincides with the face position of the previously detected face that is no longer detected, and (ii) occurs before the timeout period expires. If conditions (i) and (ii) are met, the endpoint restarts the timeout period and repeats the independently detecting motion and the determining. Otherwise, the endpoint reframes the view to encompass the remaining detected faces. |

During the call, an agent may bridge on an interactive voice response system (“IVR”) onto the call prompting the party to enter sensitive information, such as a credit card account number, to effect a payment. The information may be provided by the party using dual-tone multiple frequency (“DTMF”) tones or speech. The IVR may provide a confirmatory announcement indicating the sensitive information received. A switch may be controlled by the IVR so that any sensitive information expected from the party or provided by the IVR in a confirmatory announcement is not presented to the agent or to a recording system. In this manner, the IVR suppresses the exposure of sensitive information to the agent and/or a recording system. |

Ensuring network connection security between a wrapped app and a remote server
A network connection between an app on a mobile device and a remote server is either enabled or denied based on whether a security wrapped app can verify that the connection is with a known and trusted server. The wrapped app uses a socket interception layer injected into the app code along with a trust store, also part of the wrapped app to determine whether a network connection attempted by the app should be allowed. The layer buffers relevant function calls from the app by intercepting them before they reach the device operating system. If the layer determines that a network connection is attempted, then it snoops the negotiation phase data stream to discern when the server sends a certificate to the app. It obtains this certificate and compares it to data in the trust store and makes a determination of whether the server is known and trusted. |

A mechanism for identifying long-lived large flows in a communication network is disclosed in which packets transmitted through ports of a switching device or router are continuously examined.
