Abstract: An open architecture, wireless personal area network for receiving, storing, processing, displaying and communicating physiological data. The wireless personal area network may include a personal server, such as a cellular phone, and a plurality of sensors to monitor physiological signs, the user's motion, the user's orientation, and environmental factors. The sensors wirelessly provide data to the personal server, which may store, process, display, and communicate the data. An open architecture allows additional sensors to join the network without rendering the personal server irrelevant.

Abstract: The invention relates to a solar cell containing a semiconductor (1) with an intermediate band (2) that is half filled with electrons, located between two layers of ordinary n type (3) and p type (4) semiconductors. When lighted, electron-hole pairs are formed either by a photon that absorbs the necessary energy (5) or by two photons (6,7) that absorb less energy which pump an electron from the valence band to the intermediate band (8) and from the latter to the conductance band (9). An electrical current is generated that exits on the p side and returns via the n side. The n and p layers also prevent the intermediate band from contacting the outer metal connections, which would have resulted in a short-circuit. Said cell converts solar energy into electricity in a more efficient manner than conventional cells and contributes to improvement of the photovoltaic devices.

Abstract: A system for analyzing and structuring business processes implemented in software to provides businesses with tools to manage business processes. The system i) notifies the user that he or she has a step to begin or to complete; ii) provides the user with the proper tools to complete a task; iii) provides the user with the proper information to complete a task; iv) allows the user to see where a task fits in the overall process; v) manages proper reminders, alerts, and follow-ups to keep the process moving; vi) automates certain standard procedures; vii) integrates with the organization's existing business systems; and viii) provides application program interfaces that allow developers to develop applications that are workflow-enabled. The system utilizes a workflow server including a transactions manager and a database.

Abstract: The invention is a method and system which provides consultants, business process analysts, and application developers with a unified tool with which to conduct business process analysis, design, and documentation. The invention may be implemented using a software system which has two functional sets. One is a set of graphical tools that can be used by a developer or business analyst to map out business processes. The second is a set of tools that can be used to document and specify in detail the attributes of each workflow definition, including roles, timing, conditions of satisfaction, forms, and links required to complete a business process definition. The invention utilizes fundamental concept of workflow analysis that any business process can be interpreted as a sequence of basic transactions called workflows.
