Abstract: A roulette wheel-type funnel device for use with a hopper of a paintball marker is configured according to the hopper and essentially includes a funnel body and a roulette wheel. The funnel body is formed therein with a receiving chamber connected with a ball channel. The ball channel is in tangential communication with the receiving chamber so as to form a smooth guide path. A covering plate formed adjacent to an inlet of the ball channel and has an inclined surface and extends into the receiving chamber. The roulette wheel has a sloped surface formed with at least one fin. The roulette wheel is driven to rotate by a motor and facilitates rolling of paintballs. With the ball channel being in tangential communication with the receiving chamber and forming the smooth guide path, the paintballs are fed easily and smoothly into the ball channel and prevented from being stuck.

Abstract: An electric curtain mainly utilizes a covering sheet furled at an upper limit position, which simultaneously impels an actuating member of a zero device to relatively cooperate with a sensor of the zero device, so that the covering sheet would not continue operating and a counter in the zero device would recount once a processing unit of a controlling device receives a signal from the sensor. Thus, the processing unit would drive the counter to recount in every following drop of the covering sheet to accurately control the suspending position without incurring an accumulative counting error and increase an operative convenience.

Abstract: An operating method for an integrated interface of a PDA and a wireless communication system includes the following steps. Firstly, when the wireless communication system starts to operate from a standby mode, a state signal is transmitted from the wireless communication system to the PDA. Then, if the PDA receives the state signal when the PDA is in a sleep state, the PDA is wakened and an input source of an audio element inside the PDA is switched to the wireless communication system. An electromagnetic wave signal is received by a wireless communication element and converted into audio data. Afterwards, the audio data is transmitted from the wireless communication system to the PDA and outputted by the audio element.

Abstract: A foldable holder connecting to and supporting a display comprises a mount and a swinging part. The mount comprises a base and a pillar disposed on the base. The swinging part pivots around the pillar. The display, is disposed at a front side of the swinging part. The swinging part may be folded together with the display so as to be parallel with the base of the mount. Thus, the wasted space caused by the irregular geometry of the holder and the supported LCD can be significantly reduced. The design will greatly simplify the processes of packing, handling, and storage; therefore significantly lower the cost of business shipment. Since most of the unused space in the carton box is eliminated, the quantity of Styrofoam used as filler can also be significantly reduced, which contributing to environmental protection.
