<span lang="EN-US">Real-time acquisition and processing of electroencephalographic signals have promising applications in the implementation brain-computer interfaces. These devices allow user to control a device without performing motor actions, are usually made up biopotential stage personal computer (PC). This structure is very flexible appropriate for research, but final users it nece...

Many patients with upper limb intention tremor encounter difficulties in mouse-driven interaction with the personal computer (PC). An assistive technology system ("the Tremor Control System"), consisting of a motion-filtering software program that supports multiple interfaces, was developed and validated with 36 persons with Multiple Sclerosis in a multi-center trial. PC-tests, requiring basic ...

With the advent of readily available wireless communications and small hand-held computers, commonly known as personal digital assistants (PDAs), it is interesting to consider using these portable devices to access a control system. We have successfully ported the Experimental Physics and Industrial Control System (EPICS) to Windows CE 3.0 (WCE) for the Pocket PC (PPC), and this paper describes...

The evolution of technological systems is hindered by systemic components, referred to as reverse salients, which fail to deliver the necessary level of technological performance thereby inhibiting the performance delivery of the system as a whole. This paper develops a performance gap measure of reverse salience and applies this measurement in the study of the PC (personal computer) technologi...

This work presents an eye-tracking and pupil size-measuring device that interfaces with a computer for applications useful in psychometry, ophthalmology, physiology and virtual reality (VR) systems. This system utilizes a change-coupled device (CCD) camera, appropriate lenses, PC with frame grabber and a DSP unit with various types of VR equipment, i.e., HMD, simulator or LCD projection device....

Personal computers which have I/O slots for the insertion of plug-in interface cards are widely used in laboratory and other applications where realtime control and data acquisition are required. Two of the most popular personal computers used in this way are the Apple II and the I BM Personal Computer. The Apple II has an eightslot I/O bus and 2k addresses reserved in the memory map for I/O us...

People use personal data assistants in the field to collect data and to communicate with others both in the field and office. The individual in the office invariably has a laptop or a high-end personal workstation and thus, significantly more computing power, more screen real estate, and higher volume input devices, such as a mouse and keyboard. These differences give the high end user the abil...

Background: A personal computer (PC) is a device with wide existence and use in modern societies. A PC user is exposed to a wide range of electromagnetic fields (EMFs). Objectives: This work aimed to investigate the possible effects of radiation emitted from computer monitor on the oxidant/antioxidant status of workers. Potential ameliorative effects of zinc (Zn) on antioxidant status was consi...

The Faculty of Engineering, Mulawarman University's equipment warehouse is divided into the office-stationery and damaged-goods warehouse. Office-stationery stores office stationery, spare parts, consumables. Meanwhile, for damaged goods various such as furniture, Personal Computer (PC) components, electronic goods, laboratory equipment. problem with that many items need to be better organized ...
