This paper reports on the results of an experiment involving a wearable sensorimotor enhancer intended to improve tactile sensitivity in human fingertips. As briefly exposing receptors subsensory vibration is known enhance thanks phenomenon called stochastic resonance somatosensory system, applying white-noise fingertip expected sense touch and associated motor skills. Against such background, prototype device proposed here. The attached radial side stimulates by from lead zirconate titanate...
This article proposes a virtual hand and training system for controlling the MyoBock—the most commonly used myoelectric prosthetic worldwide. As is controlled using method also adopted MyoBock hand, proposed provides upper-limb amputees with operation sensibilities similar to those experienced in control. It can display an additional provision of instructions on operation, such as recommended posture object grasping trajectory desirable reach target. In control experiments conducted amputee...
Assistive suits reduce human muscle effort by improving motion. However, most assistive are bulky, expensive, need external power sources, and impractical to carry everywhere. We present the development of pneumatic gel muscle, which can be actuated very low air pressure, its characteristics comparing with a commercially available artificial muscle. also discuss design an unplugged powered suit for walking assist that unloads using demonstrating forces applied without use compressor or...
A cost-effective gait analysis system without attachments and specialized large environments can provide useful information to determine effective treatment in clinical sites. This study investigates the capability of a single camera-based pose estimation using OpenPose (OP) measure temporo-spatial joint kinematics parameters during with orthosis. Eleven healthy adult males walked under different conditions speed foot progression angle (FPA). Temporo-spatial were measured OP...
The lower limbs of the human body are responsible for locomotion and maintaining a good quality life. However, there many instances muscle fatigue or injuries caused by stressful work environments, aging, that involves walking long distance. Therefore, is need an assistive suit can unload efforts during reduce chances lower-limb fatigue. In this letter, we discuss development lightweight wearable augmented (AWS) using pneumatic gel its actuation control limb pose detection mechanism...
The upper limb of the human body has a higher likeliness getting affected by muscle fatigue and injury, due to repetitive motion. This letter presents an interactive glove for wrist body. assistive model is enabled with pneumatic actuators stretch sensors, which support user in performing flexion, extension, pronation, supination. purpose this provide subject force-feedback feeling, while practice such training done, rehabilitation can be achieved. For evaluation, surface electromyographical...
PURPOSE To evaluate the therapeutic significance of cisplatin, vincristine, doxorubicin, and etoposide (CODE) plus granulocyte colony-stimulating factor (G-CSF) compared with cyclophosphamide, alternating cisplatin (CAV/PE) for extensive-disease (ED) small-cell lung cancer (SCLC). PATIENTS AND METHODS Two hundred twenty-seven patients were randomized. CODE consisted 25 mg/m2 weekly 9 weeks; vincristine 1 on weeks 1, 2, 4, 6; doxorubicin 40 80 3 days 3, 5, 7, 9. G-CSF 50 micrograms/m2 was...
In this paper, a grip-force control of an elastic object is proposed based on visual slip margin feedback. When pressed and slid slightly rigid plate, partial slip, called "incipient slip" occurs the contact surface. The between plate estimated analytic solution Hertzian model. A 1 DOF gripper consists camera force sensor developed. can be from tangential measured by sensor, deformation radius area both camera. method, friction coefficient not explicitly needed. grip controlled direct...
A 73-year-old man with mild inactive interstitial pneumonitis and non-small cell bronchogenic carcinoma developed a cell-mediated hypersensitivity within 15 days following second exposure to paclitaxel. Histological features of transbronchial lung biopsy were consistent pneumonitis. Bronchoalveolar lavage showed increased lymphocytes eosinophils, decreased helper/suppressor T lymphocyte ratio. Leukocyte migration inhibitory test was positive for These results support the possibility that...
This paper proposes a probabilistic neural network (NN) developed on the basis of time-series discriminant component analysis (TSDCA) that can be used to classify high-dimensional patterns. TSDCA involves compression time series into lower dimensional space using set orthogonal transformations and calculation posterior probabilities based continuous-density hidden Markov model with Gaussian mixture expressed in reduced-dimensional space. The incorporated an NN, which is named (TSDCN), so...
PURPOSE To determine the effects of irinotecan (CPT-11) given in combination with etoposide (VP-16) metastatic non-small-cell lung cancer (NSCLC), to evaluate response and survival rates, qualitative quantitative toxicities chemotherapy. PATIENTS AND METHODS Sixty-one NSCLC patients received concurrent administration CPT-11 VP-16 for 3 days recombinant human granulocyte colony-stimulating factor (rhG-CSF) support. RESULTS Fifty-nine were assessable all 61 toxicity survival. Fifty-six treated...
Goldmann applanation tonometry is commonly used for measuring intraocular pressure (IOP) to diagnose glaucoma. However, the measured IOP by conventional valid only under assumption that all subjects have same structural eye stiffness. This paper challenges in vivo measurement of stiffness with a noninvasive approach and investigates individual differences Eye defined applied force displacement cornea. The detected based on captured images high resolution camera. experimental results show...
This paper presents the design and development of robotic tweezers with a force- displacement-sensing capability driven by piezoelectric stack actuators. In order to satisfy sufficient stroke tip force for future medical operations, rhombus strain amplification mechanism is adopted. One serially connected actuators nested in end effector used as sensor. The force-displacement characteristics at outermost layer respect forces innermost PZT (i.e., forward model) obtained from lumped parameter...
Haptic information is crucial in the execution of precise dexterous manipulations. Laparoscopic surgery, a type minimally invasive requires that surgeon senses force about tissue through forceps, because he or she cannot touch organs directly. We propose concept surgical grasping forceps with enhanced sensorimotor capability based on attaching vibrator to forceps' grip by evoking stochastic resonance (SR) effect. To apply appropriate vibrations, summing network FitzHugh-Nagumo neurons was...
