摘要:
A system for measuring golf club parameter data on impact of a club face of a user's golf club with a target surface includes a static impact bag having a front facing surface for receiving an impact thereon with the club face, and a plurality of sensors for detecting force data upon impact of the club face with the front facing surface. The system includes a processor connected to sensors for receiving the force data and determining golf club parameter data related to the club face's impact with the front surface of the bag.

A system for measuring golf swing parameter data on impact of a club face of a user's golf club with a target surface includes an absorber bag having a front facing surface with target image thereon for receiving an impact of the user's club face therewith, an anchor frame to which the bag is attached thereto, and an electronics module removably attachable to the anchor frame. The system further includes a plurality of shock mounts positioned between the absorber bag and anchor frame, and at least one accelerometer in electrical communication with the electronics module and arranged on a rear surface of the bag that measures acceleration upon impact of the club face with the absorber bag, providing a signal that is converted by the electronics module into golf swing parameter data for display to the user.

The invention relates to a method for producing biperiden by reacting exo-1-(bi-cyclo[2.2.1]hept-5-en-2-yl)-3-piperidino-1-propanone with a phenylmagnesium compound. According to the invention, exo-1-(bi-cyclo[2.2.1]hept-5-en-2-yl)-3-piperidino-1-propanone can be obtained by reacting the exo-ether of enol silylene of formula (IV) with a compound of N-methylenepiperidinium.

A tonneau cover is arranged to mount on the truck box of a conventional pick up truck for enclosing the box. The cover comprises a pair of panels which are pivotally mounted on respective sides of the box. The panels extend laterally inward such that free ends of the panels engage each other in a closed position. The panels may be pivoted upward and secured in an upward orientation by a pair of rails connected between the free ends of the respective panels in an extended position of the panels. The panels form a pair of side walls in the extended position for supporting large cargo in the box. The rails form a rack in the extended position for supporting additional cargo thereon. A locking device secures the panels in the closed position while a plurality of struts provides additional support to the panels when pivoting the panels between the closed and extended positions.
摘要:
In an interface circuit for connection to an output of a frequency converter, at least two current paths are coupled to one another in parallel. Each current path includes at least one cascode stage for signal processing. The circuit compensates for DC voltage offsets of the frequency converter, and has a gain ratio that can be changed over for signals with a large dynamic range.

The invention relates to a method for the production of biperiden by reacting an exo/endo mixture of 1-(bicyclo[2.2.1.]hept-5-en-2-yl) 3-piperidino-1-propanone with a phenyl magnesium compound, wherein the exo/endo ratio of 1-(bicylo[2.2.1]hept-5-en-2-yl)-3-piperidino-1-propanone is at least 4.5:1.
摘要:
A process for preparing doxazosin mesylate in modification A which comprises dissolving doxazosin with methanesulfonic acid in methanol or a mixture of an aprotic, polar organic solvent and methanol, removing any turbidity from the resulting solution, and stirring the resulting clear solution until no further precipitate separates out, removing, washing with methanol, heating the precipitate in the moist state in ethanol and, after cooling, isolating the resulting product is described.
