PURPOSE Portable sleep monitors may offer a convenient method to expand detection of obstructive sleep apnea (OSA), yet few studies have evaluated this technology in vulnerable populations. We therefore aimed to assess the feasibility and acceptability of portable sleep monitors for detection of OSA in a prediabetic, urban minority population. METHODS We recruited a convenience sample of part...

Background: Electromyography (EMG) signal processing and Muscle Onset Latency (MOL) are widely used in rehabilitation sciences and nerve conduction studies. The majority of existing software packages provided for estimating MOL via analyzing EMG signal are computerized, desktop based and not portable; therefore, experiments and signal analyzes using them should be completed locally. Moreover, a...

This article investigates into the feasibility of using gamma radiation Compton backscatter spectra as a means of material characterization, with the view to developing a portable, hand held probe for investigative purposes such as searching for illicit substances hidden in wall or car door cavities.

OBJECTIVE The first aim of the study was to make an inventory of the currently available ultrasound imaging devices on the market. The second aim was to identify portable ultrasound devices which could be used in general dental offices to image salivary glands, masticatory muscles and lymph nodes. Material and Methods : A list of ultrasound devices was collected from 11 international and Americ...

Negative Pressure Wound Therapy (NPWT) has been in use for over 15 years. It has been shown to promote granulation tissue and stimulate angiogenesis thereby improving wound healing. Traditionally NPWT is bulky making it use in the outpatient setting a challenge. A portable negative pressure wound system has been developed, facilitating its use in the outpatient setting. We present 4 cases highl...

This article begins by reviewing the relevant research literature concerning the portable revolution in education. It outlines the advantages and disadvantages of portable forms of technology, with an emphasis on their potential impact upon student learning and attitudes. (The focus is on mathematics as far as possible, but writing is touched upon too as it is the main use for computers in scho...

The construction of original functional sample of the portable device for fast analysis of energetic materials has been described in the paper. The portable device consisting of two parts – an original miniaturized microcolumn liquid chromatograph and a unique chemiluminescence detector – has been proposed and realized. In a very short time, this portable device is capable of identifying select...

We describe a technique called lookaside caching that combines the strengths of distributed file systems and portable storage devices, while negating their weaknesses. In spite of its simplicity, this technique proves to be powerful and versatile. By unifying distributed storage and portable storage into a single abstraction, lookaside caching allows users to treat devices they carry as merely ...

Portable RK is a portable implementation of a resource kernel, a resource-centric approach to build a real-time kernel that provides explicit timely, guaranteed and enforced access by applications to system resources [13]. Portable RK is designed to work with widely available operating systems with minimal changes. This facilitates experimentation in a familiar software environment and helps th...

OBJECTIVES In a job site, a portable fan is often used to ventilate a confined space. When a portable fan is applied to such a space, the actual ventilation flow rate must be accurately estimated in advance because the safety level of contaminant and oxygen concentrations in the space will determine the ventilation requirements. When a portable fan is used with a flexible duct, the actual flow ...
