Abstract: A patient treatment unit and method analyzes and treats pain in tissues by applying an electrical pulse train to the affected tissue. The impedance of the affected tissue is measured, and the measured impedance is correlated to a level of pain in the patient. The pulse train is further applied in response to the measured impedance to reduce the patient's pain. The patient treatment unit includes a probe stimulus generator that outputs the pulse train. The treatment unit also includes a pair of probes for contacting the patient's body and receiving the pulse train. The pulse has improved shaping based on isolation of high voltage from a low voltage control. The unit further includes a body impedance analysis circuit that senses voltage and current via the probes when the probes are contacting the patient and observe the impedance. A monitor is electrically coupled to the body impedance analysis circuit and provides an indication of the measured impedance indicative of the patient's level of pain in real-time.

Title: Cleaning formulations with improved surfactant solubility and methods of production and use thereof
Inventor: GERMAIN ADAM W
IPC: C11D3/00
Filed: 2012-09-20
Abstract: The present invention provides liquid cleaning compositions useful in cold water and hard water laundry applications, and methods for making and using such compositions.

Abstract: A narrow pulse filter circuit with automatic compensation and a motor controller applying same. The motor controller includes a PWM signal generator and an inverter unit. A plurality of signal outputs of the PWM signal generator are respectively installed with a narrow pulse filter circuit with automatic compensation. An output of the narrow pulse filter circuit with automatic compensation is connected to an input of the inverter unit. The narrow pulse filter circuit with automatic compensation includes a signal shaping circuit (1), a filter circuit (2) and a pulse width compensation circuit (3). An input signal is sent to the filter circuit (2) after being processed by the signal shaping circuit (1). The filter circuit (2) filters out the narrow pulses of the input signal. The wide pulses of the input signal are output after being compensated by the pulse width compensation circuit (3). By way of connecting a narrow pulse filter circuit with automatic compensation between a PWM signal generator and an inverter unit, the narrow pulses in a signal output by the PWM signal generator can be filtered out, and the normal pulses pass through entirely, so that the pulses input into the inverter unit are normal pulses, which effectively protects power elements IGBT and makes the control more accurate.
