Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution.
Using a community of distributed electronic agents to support a highly mobile, ambient computing environment
InactiveUS7036128B1Minimize dependenciesIncreased leverageDigital data information retrievalInterprogram communicationJet aeroplaneApplication software
A highly mobile, ambient computing environment is disclosed for serving a knowledge worker away from the their desk. The present invention allows a knowledge worker to get increased leverage from personal, networked, and interactive computing devices while in their car, airplane seat, or in a conference room with others. An Open Agent Architecture is used to incorporate elements such as GPS agents, speech recognition, and opportunistic connectivity among meeting participants. Communication and cooperation between agents are brokered by one or more facilitators, which are responsible for matching requests, from users and agents, with descriptions of the capabilities of other agents. It is not generally required that a user or agent know the identities, locations, or number of other agents involved in satisfying a request, and relatively minimal effort is involved in incorporating new agents and “wrapping” legacy applications. Extreme flexibility is achieved through an architecture organized around the declaration of capabilities by service-providing agents, the construction of arbitrarily complex goals by users and service-requesting agents, and the role of facilitators in delegating and coordinating the satisfaction of these goals, subject to advice and constraints that may accompany them.

In an environment in which some forms are received in paper form and some in electronic form or an environment in which in which workers prefer using paper forms, the invention provides a method of producing a template for the purpose of producing paper forms from electronic forms, the paper forms produced from the electronic forms being similar in appearance to forms that were completed in hard copy. Variable information is extracted from one or more electronic forms that are to be mapped to the paper form. A template is created by placing the variables from the electronic form onto an image of the paper form. The template may include position coordinate information, variable name information, text, and logic. After the template is completed, the system uses the template to print paper forms from instances of electronic forms. In some cases, multiple electronic forms can be mapped to a single paper form, and a preferred system can create a template, even if questions presented in electronic forms vary, depending on answers of previous questions.
