Abstract: The present invention relates to the use of compounds of formula (I) and formula (II) and/or pharmaceutically acceptable salts of the aforementioned compounds in the treatment of meningioma and the reduction of the recurrence rate of meningioma. In formulas (I) and (II), R1 is C1-C20 alkyl, C3-C10 cycloalkyl, C6-C20 aryl, C1-C20 alkoxy, C6-C20 aryloxy, or halogen; p is 0 to 3; R2 is H, C1-C20 alkyl, or C6-C20 aryl; and R3 is H, C1-C20 alkyl, C3-C10 cycloalkyl, or C6-C20 aryl.

Abstract: An integrated driving information displaying device for a vehicle comprises an information display unit,. a character memory and a memory card. The information display unit is installed in the rear view mirror housing, in the surface of the rear view mirror housing is formed a slot for insertion of the memory card. After insertion of the memory card, the information display unit will read the character code or symbol code in the memory card, and-the shape of character corresponding to the code will be read by the character memory and will finally be displayed on the information display unit on the rear view mirror. The integrated driving information displaying device can facilitate the driver's drive and reduce the cost for installation of other equipments.

Abstract: Consistent with one embodiment of the invention, a GPS signal processing system uses a behavior observer to monitor user dynamics and to aid a time-varying-gain filter arranged to perform continuous position and speed estimates. The behavior observer consists of a fast observer and a signal detector. The fast observer tacks user maneuvers. The signal detector compares outputs of the fast observer and the time-varying-gain filter to determine user dynamics and corrects operations of the time-varying-gain filter. Tracking ability is improved without degradation in steady-state position accuracy.
