Hand hygiene plays an important role in both healthcare institutions and food processing industries. This paper describes a tracking and localization method for hand hygiene activity monitoring. The localization algorithm was developed to identify different subjects with mobile tags within a predefined area near the hand-washing sink A demo system was constructed that was comprised of a system server,...
Background. Internet-based tele-audiology is expected to relieve the dilemma between the lack of resources and high demand of audiological care services. This paper presents a web services based, distributed pure-tone hearing assessment system that improves accessibility of traditionally underserved groups to audiology care. Methods. The system employs browser-server network architecture to connect...
This paper presents a Web services based, distributed system that allows remote pure tone hearing tests. The system network follows browser-server architecture, which minimizes hardware and software requirements on the client computers and makes hearing test services more accessible to traditionally underserved population groups. Thanks to the three tier software design, the system functionality is...
This paper reports a new signal processing method for biometric identification purposes that utilizes signals collected from a cost-effective wearable electro-cardiogram (ECG) sensor. In this method, raw ECG signals were first prepared in the time domain and then decomposed into a structure of coefficients using wavelet algorithms. This coefficient structure was further extended to a coefficient matrix,...
Photoplethysmographic (PPG) signals contain rich personal information that can be used to distinguish individual subjects. This paper discusses the design of an analog amplification circuit for PPG signals to remove the DC component of the signal. By adding an amplifier bias-adjusting circuit, a high signal-to-noise ratio AC signal can be acquired from the raw PPG signal. This hardware improvement...
Photoplethysmographic (PPG) signals are easy to obtain with low cost, which enhances its potential to server as biometric identification mechanism for various applications. This paper examines two important issues in applying derivatives of PPG signals as discriminants to identify and verify subjects: consistency within an individual subject and discriminability between different subjects. The experimental...
