We present a low-cost, portable, wireless diffuse optical imaging device. The handheld device is fast, portable, and can be applied to a wide range of both static and dynamic imaging applications including breast cancer, functional brain imaging, and peripheral artery disease. The continuous-wave probe has four near-infrared wavelengths and uses digital detection techniques to perform measureme...

This paper introduces a peripheral device that supports communication especially in terms of expressive power in mobile environments. As people can speak and hear while doing something else without losing concentration very much, sound has been chosen as a communicating medium not to prevent the daily use of the device. Referring to the conditions recognized by an electronic sensory system, the...

Embedded systems are highly optimised to operate in the physical world they are embedded to. Hence, dedicated peripheral devices are designed which need support by a device driver to raise the level of abstraction for the application programmer. Even with methods of hardware/software co-design, devices and drivers are still designed by two designer groups. This paper depicts a systematic approa...

The occurrence of physiological artifacts generated by eye movements in electrical brain activity (electroencephalography, EEG) is a well-known problem clinical practice. In order to increase the accuracy detection during EEG examination, additional electrooculogram channels (electrooculography, EOG) with standard PC keyboard are used. EOG technique not always comfortable for patients. Another ...

The short peripheral catheter (SPC) is the most common vascular access device used in the health care arena. That use is growing every year with approximately 330 million short peripheral catheters sold in the United States in 2012. The projected growth in the US population, along with an aging population and rising morbidity rates, will contribute to an increased need for vascular access devic...

The ubiquitous and pervasive use of lighting effects embedded into peripheral hardware has gained popularity through it’s use in Triple-A video game titles such as Call of Duty and the availability of software development kits (SDK) from leading manufacturers. A preliminary NASA TLX experiment was performed to examine the effect that notifications displayed on a peripheral device has, in compar...

Embedded peripheral devices such as memories, sensors and communications interfaces are used to perform a function external to a host microcontroller. The device manufacturer typically specifies worst-case current consumption and latency estimates for each of these peripheral actions. Peripheral Activity Completion, Estimation and Recognition (PACER) is introduced as a suite of algorithms that ...

background: symmetrical peripheral gangrene is usually associated with underlying medical problems and it is seldom seen in pregnancy. sepsis though common in a setting of delivery by unskilled midwife is rarely accompanied by symmetrical gangrene. case presentation: we report a case of symmetrical peripheral gangrene which occurred in the winter, triggered possibly by sepsis and a single dose ...
