Abstract: A smart case configured to encapsulate a mobile communication device. The smart case includes a radio embedded in the case for selectively enabling the encapsulated mobile communication device to communicate over a wireless network using either the radio embedded in the case or the Wi-Fi and/or cellular radio in the communication device itself. In alternative embodiments, either a hard switch, a soft switch, or both, is provided for switching between either the radios(s) embedded in the smart case or the internal radio(s) in the mobile communication device.

Abstract: A virtual Slide-to-Lock feature for communication devices running a PTT application. When the Slide-to-Lock feature is activated, a PTT locking function on the communication device is activated. As a result, messages on the communication device may be created, without the need of the user to continuously hold or select a Hold-to-Talk or similar PTT feature. In one non-exclusive embodiment, the virtual Slide-to-Lock feature is activated when a finger is moved from a first region to a second region on a touch-sensitive display screen and de-activated with the opposite motion.

Abstract: A telecommunication and multimedia management apparatus and method that supports voice and other media communications and that enables users to: (i) participate in multiple conversation modes, including live phone calls, conference calls, instant voice messaging or tactical communications; (ii) review the messages of conversations in either a live mode or a time-shifted mode and to seamlessly transition back and forth between the two modes; (iii) participate in multiple conversations either concurrently or simultaneously; (iv) archive the messages of conversations for later review or processing; and (v) persistently store media either created or received on the communication devices of users. The latter feature enables users to generate or review media when either disconnected from the network or network conditions are poor and to optimize the delivery of media over the network based on network conditions and the intention of the users participating in conversations.

Abstract: A system for progressively synchronizing stored copies of indexed media transmitted between nodes on a network. The system includes a transmitter at the sending node configured to progressively transmit available indexed media to a receiving node with a packet size and packetization interval sufficient to enable the near real-time rendering of the indexed media, wherein the near real-time rendering of the indexed media provides a recipient with an experience of reviewing the transmitted media live. The system also includes a receiver at the receiving node that progressively receives the transmitted indexed media and continually notes any indexed media that is not already locally stored at the receiving node. The receiver also continually generates and transmits to the sending node requests as needed for the noted indexed media. In response, the transmitter at the sending node transmits the noted indexed media to the receiving node.

Abstract: A proximity sensor system for use with mobile communication devices that reduces the incidence of false positives. The proximity sensor system includes a first sensor and a second sensor, each of which are configured to separately generate outputs indicative if the mobile communication device should operate in a handset mode or a speakerphone mode. The system further includes a processor configured to switch the operation of the mobile communication device between the handset mode and the speakerphone mode when both outputs indicate that the mobile communication device should be in one mode or the other. By relying on both first and second sensors, the incidence of false positives is reduced. In various alternative embodiments, multiple first sensors and/or second sensors may be used.

Abstract: A voice and text mail application method and apparatus capable of supporting both synchronous and asynchronous voice communication. The application is configured to (i) simultaneously and progressively store media of an incoming message as the media is received at a communication device over the network and (ii) provides a “catch up” rendering option which enables the rendering of previously received media of the message starting at any previous point of the message and to catch up the rendering to the current point or head of the message as the media of the message is being received. By rendering the previously received media of the incoming message out of storage at a rate faster relative to when the media of the incoming message was originally encoded, eventually the rendering will catch up and seamlessly transition the rendering from an asynchronous time-shifted mode out of storage to a synchronous mode as the media of the message is received over the network.

Abstract: A network communication device located on a Push To Talk (PTT) communication network and configured to provide time-shifting capabilities to a user of a PTT communication device is disclosed. The network communication device includes a receiver configured to progressively receive time-based media. The network communication device also includes a time-shifting buffer for progressively storing the received time based media as the time-based media is received and a time-shifting buffer controller configured to control the rendering of the time-based media at the PTT device.

Abstract: A browser enabled communication device capable of conducting conversations, including multiple media types, in either a real-time or a time-shifted mode, with the ability to seamlessly transition between the two modes.

Abstract: A communication application configured to support a conversation among participants over a communication network. The communication application is configured to (i) support one or more media types within the context of the conversation, (ii) interleave the one or more media types in a time-indexed order within the context of the conversation, (iii) enable the participants to render the conversation including the interleaved one or more media types in either a real-time rendering mode or time-shifted rendering mode, and (iv) seamlessly transition the conversation between the two modes so that the conversation may take place substantially live when in the real-time rendering mode or asynchronously when in the time-shifted rendering mode.

Abstract: A method for gracefully extending the range and/or capacity of voice communication systems is disclosed. The method involves the persistent storage of voice media on a communication device. When the usable bit rate on the network is poor and below that necessary for conducting a live conversation, voice media is transmitted and received by the communication device at the available usable bit rate on the network. Although latency may be introduced, the persistent storage of both transmitted and received media of a conversation provides the ability to extend the useful range of wireless networks beyond what is required for live conversations. In addition, the capacity and robustness in not being affected by external interferences for both wired and wireless communications is improved.

Abstract: A mobile communication device and method for reducing exposure to radio frequency (RF) energy during outgoing and incoming transmissions. During outgoing transmissions, media is stored in a local storage element on the mobile communication device as the media is being created. When the device is positioned a safe distance away from the user, the media is transmitted out of storage over the network to the recipient. Alternatively for incoming transmissions, media is stored on the network as it is created. While the wireless communication device is a safe distance away from the user, the media stored on the network is transmitted to the mobile communication device, where it is locally stored. The user of the mobile communication device can then review the incoming media at an arbitrary later time out of storage. As a result, the exposure of the user of the mobile communication device to RF energy for both outgoing and incoming transmissions is either substantially reduced or eliminated altogether.

Abstract: A method for providing on a Push To Talk (PTT) communication network time-shifting capabilities to a user of a PTT communication device. The method involves progressively receiving time-based media at a node on the PTT communication network from a sending device and progressively storing the received time-based media in a time-shifting buffer located at the node as the time-based media is progressively received. In response to rendering control instructions received from the user of the PTT communication device, the method further includes controlling the rendering of the time-based media at the PTT communication device in either (i) a near real-time mode as the time-based media is progressively received at the node or (ii) in a time shifted mode at an arbitrary later time after the receipt and storage of the time-based media in the time-shifting buffer.
