Power management for a portable computer

Abstract: A power manager (PMGR) within a portable laptop computer provides power (via 26) and clocking control (via 27) to various units within the computer in order to conserve battery power. Transistor switches controlled by the power manager control the distribution of power and clock signals to the various units within the computer. The power manager includes a software routine for continually monitoring various units and when certain units are either not needed and/or not currently in use, power and/or clock signals are removed from a given unit, and the computer can be switched between three modes viz. normal, slow and sleep.

RN education flexibility utilizing laptop computers.

Abstract: In a geographic region that is largely rural, baccalaureate faculty teaching RNs needed a program of study that provided flexibility. This article describes a project that incorporates CAI and PCs into RN education. Difficulties and successes of the project are also discussed.

A low-cost and ready to run package to transform a laptop into an advanced electrocardiograph

Abstract: An electrocardiomultigraphimeter has been built which features vectorcardiography, polar coordinate tracing, automatic measurements between manually selected fiducial points and trace data filing on patient disks The result is a package designed to work on most laptop computers that exhibits advanced clinico-scientific capabilities, as compared to current electrocardiographic instruments, and ease of installation and use This new instrument should be suitable not only for offices of cardiologists but also for on-site heart analysis (ie for mobile units) and for training purposes >

ReValuator - An Expert System Approach to Actuarial Valuations

Abstract: Expert system technology has now matured so that task-oriented business programs can be rapidly proto typed, developed, coded, and deployed on desktop and laptop personal computers. This rapid development and deployment is especially true when the task is well defined, and the target user has little knowledge in the specified domain. This chapter sketches the successful implementation of an actuarial program designed to assist a non actuary in detailed actuarial analysis.During the past few years, sophisticated microprocessors have been placed in desktop and laptop computers. As a result, these computer platforms can now accommodate expert systems that once ran only on specialized computers or mainframes. The expertise captured in the knowledge-based system can be distributed on these relatively inexpensive computer platforms to locations where no expert is available for consultation.This chapter describes the development of an expert system called the ReValuator and includes the following sections: (1) Problem Definition, (2) Description of the AI Technology Used, (3) Functional Overview, (4) Architectural Overview, (5) Example of Model in Opera tion, (6) Innovations, (7) Criteria for Successful Deployment, (8) Nature and Estimate of Payoff, and (9) System Evolution.
