Abstract: A method and system to examine and measure the propagation velocity of electrical activity in pregnant patients, labor and non-labor patients at term and preterm, and non-pregnant patients, thereby providing valuable information regarding the state of a patient's uterus. The method can include obtaining uterine EMG signals from a series electrodes, processing the raw uterine EMG signal in a signal processing module and assessing the temporal interval between adjacent electrodes. The propagation velocity can then be estimated by averaging the time required for the uterine EMG signal to traverse a distance between adjacent electrodes.

Abstract: An enhanced-functionality prosthetic limb is disclosed, comprising a prosthetic hand or gripping device, and forearm, which may be body-powered or motor-powered, targeted primarily for pediatric use, attachable to the arm stump of a below-elbow, or above-elbow, with the inclusion of a prosthetic elbow, amputee individual, with incorporation of one or more of the following features: expandability in length or size to accommodate child growth or other expandability needs, grasp locking capability, individual finger locking capability, three degree of freedom wrist joint, dynamic tensional rotation control of wrist, dynamic grasp control to allow grasping of irregular objects, extended grasp for gripping larger objects, excessive force breakaway, and algorithms to support by user of care-provider adjustment of the prosthesis.

Abstract: A line tracer is disclosed comprising a transmitter for generating a signal in a target pipe, a cable set, a detector for amplifying the signal and filtering unwanted electronic noise, and a method for employing the line tracer. The transmitter further comprises a transmitter circuit board having a pulse generation circuit, a tone generation circuit and a transformer drive circuit. The transmitter circuit board is tuned to provide a pulse frequency of approximately 1.3 Hz and a tone rate of approximately 600 Hz. The detector further comprises a detector circuit board having a difference amplifier, a first high pass filter, a second high pass filter, a non-inverting amplifier, and a sensitivity meter. The detector circuit board is designed to amplify the detected signal and to achieve an attenuation of frequencies from 0 Hz to 400 Hz that is 80 dB/decade. The detector provides a visual indicator of signal strength.
