Handheld personal digital assistants

Hardware considerations for automated performance testing systems generally include the computer, software, monitor, and input devices. These features can be provided on multiple testing platforms, including personal computers, handheld personal digital assistants, Internet-based systems, or on platforms that are specially designed to simulate occupational contexts. 

The principle of a factory-wide network of production machines, however, allows a number of other applications. It is, for example, possible to access the status of a production plant anywhere in the world via the Internet - an aspect that should not be underestimated in the course of globalization. In addition, information about each production order, such as the causes of machine standstill, can be entered and recorded by the employees in production using so-called handheld personal digital assistants (PDA) via wireless local area networks (LAN). This information is finally collected and documented on the central server through the network. 

Fuel cells can be used to power a variety of portable devices, from handheld electronics such as cell phones and radios to larger equipment such as portable generators. Other potential applications include laptop computers, personal digital assistants (PDAs), and handheld video cameras—almost any application that has traditionally used batteries. These fuel cells have the potential to last more than three times as long as batteries between refueling. 

More recent advances in technology made possible by the personal digital assistant (PDA) have allowed physicians to electronically prescribe at the point of care. PDAs are handheld computers that typically run using a Windows- or other proprietary-based platforms. These PDAs use a touch-sensitive screen to maneuver through a menu-driven prescribing process that can execute a prescription in as little as three stylus taps. - The PDAs or other proprietary devices then upload the prescription via a network connection or modem to be printed, faxed, or electronically transmitted to a pharmacy. 

Advances in technology can facilitate the generation and transfer of patient documentation. As more pharmacies use the Internet as a means of communication, information can be transferred quickly and accurately over greater distances. Handheld computers and specialty software allow health care practitioners to document information in an electronic format that can be transformed immediately for rapid transfer to others. Reports in the literature have described methods to assess pharmacist interventions related to medication errors, the use of computer-based systems, and recently, the use of personal digital assistants (PDAs) in specific patient care areas. Many of these documentation systems tend to be individualized apphcations in which the transfer of data to other providers is not possible or quite limited. Often these systems focus on the generation of reports for workload analysis or accreditation purposes. 

There are dozens of choices of popular hardware platforms, depending on the size of your business or your personal preference. Software runs your business. The hardware requirements of the software define the hardware needed. Activities of daily business or lifestyle further define hardware requirements. Personal digital assistants or handheld computers have significantly improved user mobility. As wireless technology emerges, users will enjoy even greater flexibility. But at the end of the day, most hardware, even stand-alone home computers (with Internet connectivity), are networked. 

They are used in appliances including television sets, computer monitors, mobile phones, handheld video game systems, personal digital assistants, and navigation systems (e.g., Tasman Metals 2015) see also Chap. 5. 

Newton Apple introdnces Newton, one of the first handheld computers, or personal digital assistants, which has a hquid crystal display operated with a stylus. 

After only a decade of development, PLEDs indeed seem to have matured to the edge of commercial exploitation. The technology is expected to initially address the market for small- and medium-sized alphanumeric displays, as used in calculators, handheld telephones, pagers, car radios, personal digital assistants information readouts on household appliances, and in automobiles, which has a current annual volume of about US 2.5 billion, with high growth rates expected.
