We present a wide frequency range, low cost, wireless intracranial pressure monitoring system, which includes an implantable passive sensor and external reader. The consists of two spiral coils transduces the change to resonant shift. portable reader reads out sensor's over range (35 MHz-2.7 GHz). propose novel circuit topology, tracks system's impedance phase at high with low-cost components. This is very simple reliable. A prototype has been developed, measurement results demonstrate that...
Recently, application of vibrotactile noise to the wrist or back hand has been shown enhance fingertip tactile sensory perception (Enders et al 2013), supporting a potential for an assistive device worn at wrist, that generates minute vibration help elderly patients with deficit.However, knowledge regarding detailed physiological mechanism behind this improvement in central nervous system, especially human brain, is limited, hindering progress development and use such devices.To enable...
Purpose: The concept of a vibrating wristband, to improve dextrous hand function stroke survivors, was recently proposed with clinical results and is referred as ‘TheraBracelet’ in this paper. purpose study demonstrate feasibility portable, wearable TheraBracelet, apply usability evaluation techniques assess potential demands TheraBracelet identify critical improvement needs the prototype. Method: A prototype developed element housed an elastic wristband connected electronics box via cable....
The non-invasive quantification of metabolite concentration is significant importance in the fields medical diagnosis and monitoring. Functional near-infrared spectroscopy (NIRS) offers a promising optical solution for this purpose. However, conventional continuous-wave (CW) NIRS systems only record light intensity, limiting analysis absorption (μ <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a</inf> ) reduced scattering...
Hydrocephalus is a medical condition, where excessive accumulation of CerebroSpinal Fluid leads to an abnormal increase intracranial pressure (ICP). Early and timely detection elevated ICP very important mitigate symptoms during the entire life patient avoid headaches, mental disability, death caused by increased ICP. We describe our fabricated active capacitance for continuous measurement. The sensor consists two metal plates, which transduces change change. introduced novel special...
Abstract Limited by the physiological constraints, implanted intracranial pressure ( ICP ) sensor's diameter is usually much shorter than measurement distance, which related to poor coupling factor for inductance coupling‐based passive sensor. As a result, pattern of spiral planar coil on sensor needs be carefully designed; otherwise, could not detected external reader. This paper begins with an improved lumped circuit model sensor, in physical characteristics and corresponding approximated...
This study explores the use of neural network-based analytic continuation to extract spectra from Monte Carlo data. We apply this technique both synthetic and Carlo-generated The training sets for networks are carefully synthesized without ``data leakage". found that set should match input correlation functions in terms statistical error properties, such as noise level, dependence on imaginary time, time-displaced correlations. have developed a systematic method synthesize datasets. Our...
Sleep Apnea is a common sleeping disorder that affects over 25 million Americans. Due to the complex nature of sleep apnea, and human body, neither an effective nor comfortable treatment option for apnea has been developed. Accordingly, we describe novel alternative current therapies, including CPAP therapy. A device treating incorporates mask, flexible hose chamber collecting expired air containing CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML"...
