Abstract: A foldable basketball stand comprises a seat having a supporting frame, a transfer unit installed at one end of the supporting frame and a weight installed to the supporting frame; and the weight being a foldable water box; a supporting unit formed of a plurality of rod bodies; one end of the supporting unit being connected to the transfer unit of the seat; and a backboard installed at another end of the supporting unit; and the backboard having at least two plate bodies and a hoop installed between the two plate bodies. The installation of the seat, supporting unit and backboard causes the foldable basketball stand can be assembled easily for use and detached easily for storage. Thereby the volume of the foldable basketball stand is small. It can be storage and transferred easily and conveniently.

Abstract: A single-chip driving device for a high intensity discharge lamp includes a high voltage direct current electric power supply system, a power control circuit, a frequency transformation circuit, and an ignition steady current circuit. The high voltage direct current electric power supply system transforms an external power supply into a relatively higher voltage direct current electric power. The power control circuit transforms the relatively higher voltage direct current electric power into a relatively lower voltage and higher frequency direct current electric power. The frequency transformation circuit transforms the relatively lower voltage and higher frequency direct current electric power into a relatively lower voltage and lower frequency direct current electric power so as to drive the ignition steady current circuit.

Abstract: A vehicle brake indicating device has a pendulum which has a plurality of long holes. The arrangement of long holes are based on a logic truth table. Two detecting elements are on the pendulum. When the pendulum swings, the upper and lower detecting element and detecting element are placed in long holes or round arc surface which are mapped to values in a truth table; so that a set of truth values in the truth table is derived. A control circuit has an electronic circuit controller. The outputs of the electronic circuit controller are connected to the lift turn light and right turn light, a deceleration light and a staged-illumination third braking light so as to present various illuminations. By the detecting elements to detect signals which are sent to the electronic circuit controller so as to present various aleRT1ng effect.

Abstract: An improved structure of target unit for electronic guns comprising: a housing having a receiving area for movably mounting a target paper, a sensitive target provided in the housing in right opposition to the target paper and provided with a sensing circuit for sensing the electronic signals generated when in hitting of bullets, a scoring circuit connected with the sensing circuit for counting and provided with a display screen mounted on the housing to show the results of scores, and a recovering bin connected to the lower portion of the housing to collect and recover bullets, with the target unit, a virtual effect of hitting of bullets through a target paper during shooting is obtained, and bullet hitting is detected by the sensitive target to show the results of scores on the display screen, the bullets are recovered into the collecting bin.
