Abstract:
An electric nailing mechanism comprises a striker, an elastic member, one or two toothed bars, and a driving assembly. One end of the elastic member is fixed at one end of the striker. The toothed bars are disposed on a surface of the striker. The driving assembly comprises a screw, a drive gear wheel and one or two travel gears. The drive gear wheel is engaged with the screw and the drive gear wheel and the travel gears are coaxially connected together, so that the drive gear wheel and the travel gears can be rotated synchronously in the same direction. The travel gears are fan-shaped and are engaged with the toothed bars. By such arrangements, the driving assembly takes up a smaller space and the manufacture for the mechanism is much easier.

Abstract:
A geometric construction system includes: a plurality of flat panels; and a plurality of connecting units provided on side edges of the flat panels. Each connecting unit includes first and second engaging parts. The first engaging part is formed with a protrusion, and the second engaging part is formed with a recess such that the protrusion of the first engaging part on one of the flat panels is releasably engageable with the recess of the second engaging part on another of the flat panels. The second engaging part is further formed with resilient claws that project from a periphery of the recess. The claws of the second engaging part on one of the flat panels clamp resiliently the protusion of the first engaging part on another of the flat panels when the protrusion is moved into the recess of the second engaging part.

Abstract:
The present invention is a novel and improved method for monitoring the real time loading condition in a CDMA wireless communication system. The level of the power control signal is obtained by monitoring, in real time, at the base station the forward link CDMA channel, comparing this measurement to the previously obtained level, and displaying the level of the power control signal as a line which can consist of two parts. The first part can be a solid line the length of which represents the level of the power control signal in real time and the second part can be a dotted line whose length increases slowly and decreases rapidly to indicate that the level of the power control signal is rising. Conversely, a rapid increase and a slow decrease of the length of the dotted line indicates that the level of the power control signal is falling. Color coding can be used to indicate that the level of the power control signal is at or outside an optimum operating range.
