Onboard assessment of photoplethysmogram (PPG) quality could reduce unnecessary data transmission on battery-powered wireless pulse oximeters and improve the viability of the electronic patient records to which these data are stored. These algorithms show promise to increase the intelligence level of former "dumb" medical devices: devices that acquire and(More)
Pulse oximeters are central to the move toward wearable health monitoring devices and medical electronics either hosted by, e.g., smart phones or physically embedded in their design. This paper presents a small, low-cost pulse oximeter design appropriate for wearable and surface-based applications that also produces quality, unfiltered photo-plethysmograms(More)
Frameworks that promote the intelligent coordination of medical devices are required in ubiquitous health care environments. Such environments are essential to achieve closed-loop behavior, and an emphasis on interoperability standards and reconfigurable hardware/software components will allow these systems to adapt to changing patient/provider needs and(More)
– A cross-course design experience is an efficient way to stitch together two concurrent, single-semester courses to obtain a meaningful number of design credits without unduly increasing a student's overall load. This paper addresses a project that joined the design credits from two Kansas State University (KSU) courses: ECE 773 – Bioinstrumentation Design(More)
Periodic defected ground structures (PDGS) with rectangular defected areas has excellent low-pass properties when periodic unit amounts and structure sizes meet definite conditions. Microwave low-pass filter (LPF) is a kind of device which can separate different signals within microwave frequency range, widely used in microwave communication system. The(More)
