Appl. No.:

10/052087

Inventors:

Michael Becker - San Jose CA, US
Krishnakumar Narayanan - Cupertino CA, US

Assignee:

ecrio, inc. - Cupertino CA

International Classification:

G06F003/00
G06F009/00
G06F017/00

US Classification:

715753, 715772, 715777

Abstract:

A graphical user interface displays a unique graphical indexing element such as a tab for each engaged and non-engaged messaging session. The user chooses which messaging session to make engaged by selecting its graphical indexing element. The graphical indexing elements have various distinctive characteristics to indicate the status of their respective messaging sessions, such as engaged, non-engaged with no unread messages, or non-engaged with at least one unread message. The messaging sessions may all be docked, in which event the engaged messaging session is displayed in a window pane set and the other messaging sessions are not displayed, or may be selectively undocked, in which event the engaged messaging session and the undocked messaging sessions are displayed in respective window pane sets. The engaged window pane set supports the communication of original or predefined messages between the user's digital device and the pal's messaging-enabled digital device, regardless of capability.

International Classification:

G06F 3/00

US Classification:

719328

Abstract:

A services and application controller (“SAC”) is provided for digital electronic devices. The SAC includes four interfaces which respectively interact with four different environments, namely an application interface that interacts with application environments and applications, an extension interface that interacts with engines and enablers, a platform interface that interacts with device platform environments, and a service and network interface that interacts with services and service infrastructures and with networks. The SAC provides a set of core functions and abstracts the environments from each other, which enable interactions between these environments without requiring that the environments be aware of specific aspects of the other environments for the interactions.

Krishnakumar Narayanan - Pleasanton CA, US
Michel E. Gannage - Los Altos Hills CA, US

Assignee:

Ecrio, Inc. - Cupertino CA

International Classification:

H04W 88/02

US Classification:

455437

Abstract:

A distributed services modular client architecture may be used to implement IP-based real time communication services in a flexible manner among a wide variety of different types of chip sets and systems-on-chip. The various services are distributed among one or more processor cores in accordance with a number of factors, including power consumption, media latency, on-time, performance, and other considerations. A processor “core” may refer to a processor itself if single core, and may also refer to a “core” of a multicore processor. The architecture uses a SIP/IMS framework, and is modularized by placing certain services into their own framework so that a particular service may be plugged into the SIP/IMS framework if and when desired, and otherwise omitted. The frameworks may be installed on various processor cores within the chip set or system-on-chip to allow for more effective power conservation without unduly sacrificing performance.

International Classification:

G06K007/10

US Classification:

235/462460

Abstract:

A user is provided with a secure database containing information in diverse categories that relates to the user and that may be represented at least in part in bar code form and communicated with light from a mobile communications device. The diverse information is obtained from any combination of a variety of vendor and governmental computer systems, internet service providers, and communications devices. The user has access to the database using a mobile communications device for displaying, managing, and entering information, and for communicating information in bar code form with light. The user first selects the category that contains the specific item of information, and then selects the specific item of information. The specific item of information then is communicated in bar code form with light from the mobile communications device for scanning by a bar code scanner to obtain the desired good or service.

International Classification:

H04L012/28

US Classification:

370/351000

Abstract:

A notification channel based approach is used for near real time data streaming for voice. The notification channel also is used to carry small data payloads. The solution preferably includes three elements. The first element involves taking the voice input from the sender in small, digitized packets. The second element involves taking these time packets of voice data and sending them out in a sequential manner over the notification channel. At the receiving end these packets of voice data are played back through the codec supported by the platform as they are received. The third element lies in the fact that the notifications can be sent to as many recipients as required. This allows the sender to broadcast voice messages to a group of people and to implement a conference.

International Classification:

US Classification:

719311, 719328

Abstract:

To greatly simplify the developer's task, an application function server or application logic controller (“ALC”) server runs on a digital electronic device with a common set of tools and methods to deliver high-value capabilities to applications developed in different application languages and running in various different application environments. The applications and the application function server have a local client-server relationship. The functions themselves are provided by various plug-ins. The interface of a plug-in illustratively is a discrete set of functions, common to the command plug-ins. The ALC Server accepts simplified commands directly from the applications, applies the appropriate policy, and interacts with the plug-ins to perform the requested functions on behalf of the applications. The result is that applications can use various capabilities without dealing with the complex methods, standards, and system interoperability required to make the technologies work, and technology additions and upgrades can be performed independently from the applications that use them.
