摘要:
The present invention disclosed a medical use of cucurbitane triterpenoids represented by the following formula and isolated from Momordica charantia L. of Cucurbitaceae family in the preparation of medications for prevention and treatment of diabetes and obesity. The above cucurbitane triterpenoids may be acted as a glucose uptake stimulator, an agonist for the translocation of glucose transporter 4 (GLUT4) to the cell membrane, and an activator of adenosine monophosphate-activated protein kinase (AMPK). They may have potential for the prevention and treatment of diabetes and obesity.

Techniques for providing mining life pattern are described. This disclosure describes mining a life pattern of an individual, for example, by identifying places visited during the individual's daily activities. Mining the individual life pattern includes collecting location data for the individual and predicting behaviors and preferences of the individual based at least in part on a location history. The location history of the individual is represented with a sequence of geographical regions that have been visited by the individual with corresponding arrival and departure times for each region. Once the life pattern is predicted from the location history, information is recommended to the individual based at least in part on the life pattern.

A power line communication-based aircraft power distribution system may allow for both power line communication (PLC) technology and spread spectrum time domain reflectometry (SSTDR) technology to be utilized in aircraft power distribution systems to achieve key maintenance functions. Unlike conventional power distribution systems, which may, for example, use only SSTDR for fault detection, the present invention includes a hardware platform that may allow both the PLC and the SSTDR to be utilized in aircraft power distribution systems to achieve key maintenance functions, such as real time wire fault location, and cost and weight savings. Further, unlike conventional power distribution systems, which may only detect and locate damage in feeder conductor wire sections before the power is applied to the load, the power distribution system of the present invention may permit real time wire fault location.

An AC/DC power converter has, as its first stage, a capacitor divider and rectifier and, as the second stage, a switch mode power supply. This configuration may be suitable for low power low voltage aerospace applications. The benefits of the circuit may include small reactive component size; near sinusoidal input current, low EMI emissions resulting from low inrush current; intrinsic current limiting that may eliminate the need for short circuit protection; and low overall component count.

A virtual ΔT trip criterion is implemented in an electrical power distribution system to provide current-based tripping for a solid state power switching device. A first-order system model is implemented either by hardware or software to represent a rise in temperature of the electrical wire through which power is supplied. When the simulated temperature exceeds a threshold, the solid state power switching device may be tripped.

摘要:
An electrical overload protection system may be based on a solid state control system. A solid state switch may open responsively to commands for a solid-state controller. The controller may perform calculations to determine accumulated energy in a protected conductor. The calculations may be based, in part, on samplings of current in the protected conductor and ambient temperature to which the conductor may be exposed.
