Tunneling VoIP call control on cellular networks
Signaling from a mobile device is transparently tunneled through a cellular voice network to a Voice over Internet Protocol (“VoIP”) core network so that multi-party calls, including conference calls and call waiting, can be managed entirely within the VoIP core network. The tunneled signals enable call control to be implemented in the VoIP core network and also establish a way to communicate requests, instructions, and call state. The signaling is transparent to the cellular network because that network does not receive and interpret the signaling. Instead, the cellular network's existing and unmodified control plane is repurposed by the mobile device by placing new, brief outgoing calls through the cellular network to the VoIP core network where the called party number (i.e., the caller-ID) encodes specific information. The VoIP core network immediately releases the new cellular call once the caller-ID is received and the encoded information is interpreted. |

Electronic signature framework with enhanced security
Improved document processing workflows provide a secure electronic signature framework by reducing attack vectors that could be used to gain unauthorized access to digital assets. In one embodiment an electronically signed document is removed from an electronic signature server after signed copies of the document are distributed to all signatories. The electronic signature server optionally retains an encrypted copy of the signed document, but does not retain the decryption password. This limits the amount of data retained by the electronic signature server, making it a less attractive target for hackers. However, the electronic signature server still maintains audit data that can be used to identify a signed document and validate an electronic signature. For example, a hash of the document (or other document metadata) can be used to validate the authenticity of an electronically signed document based on a logical association between an electronic signature and the signed document. |

Adaptive synchronous protocol for minimizing latency in TDD systems
Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases. |

A second sealing material such as a mold resin is deposited into a second subset of the gaps. The first and second sealing materials are cured, and the die stacks are then singulated. |

Wire bonding method and apparatus for electromagnetic interference shielding
Apparatuses relating generally to a microelectronic package having protection from electromagnetic interference are disclosed. In an apparatus thereof, a platform has an upper surface and a lower surface opposite the upper surface and has a ground plane. A microelectronic device is coupled to the upper surface of the platform. Wire bond wires are coupled to the ground plane with a pitch. The wire bond wires extend away from the upper surface of the platform with upper ends of the wire bond wires extending above an upper surface of the microelectronic device. The wire bond wires are spaced apart from one another to provide a fence-like perimeter to provide an interference shielding cage. A conductive layer is coupled to at least a subset of the upper ends of the wire bond wires for electrical conductivity to provide a conductive shielding layer to cover the interference shielding cage. |

Reducing solder pad topology differences by planarization
A technique is disclosed for causing the top surfaces of solder bumps on a chip to be in the same plane to ensure a more reliable bond between the chip and a substrate. The chip is provided with solder pads that may have different heights. A dielectric layer is formed between the solder pads. A relatively thick metal layer is plated over the solder pads. The metal layer is planarized to cause the top surfaces of the metal layer portions over the solder pads to be in the same plane and above the dielectric layer. A substantially uniformly thin layer of solder is deposited over the planarized metal layer portions so that the top surfaces of the solder bumps are substantially in the same plane. The chip is then positioned over a substrate having corresponding metal pads, and the solder is reflowed or ultrasonically bonded to the substrate pads. |
