Abstract: An automatic score dartboard assembly has a base, a dartboard, a support, at least one imaging element and a main control circuit. The dartboard and the support are attached to the base, and the at least one imaging element is mounted on the support to capture a direct viewing image of the dartboard periodically. The images are output to the main control circuit to determine the score of a dart when the dart sticks in the dartboard. The main control circuit is composed of an image processor and a memory device. The image processor uses an image comparison method to determine the score of the dart. Therefore, the present invention uses as few as one imaging element to determine the score and increases accuracy of determining score.

The lamps each have two straight portions and a connection portion. The lamps have the straight portions and the connection portions arranged in the window region of the frame. The light shade device has a top mask extended over the connection portions of the lamps respectively. The top masks have a predetermined transparency to shade a part of the light provided from the connection portions of the lamps respectively.

Abstract: A treadmill includes a base assembly, a collapsible treadmill deck and a locking device that includes a telescopic tube and a latch. The telescopic tube supports the treadmill deck in a folded position and includes an inside tube and an outside tube. The outside tube has a pawl hole and a bottom end pivotally mounted to the base assembly. The inside tube is telescopically mounted in the outside tube and has an outside end pivotally mounted on the treadmill deck and multiple positioning holes aligned with the pawl hole. The latch includes a stationary bracket fastened on the outside tube and a pivot pawl pivotally mounted on the stationary bracket. The pivot pawl has an inside end extended into the pawl hole to engage one of positioning holes to interlock the inside tube with the outside tube to firmly hold the folded treadmill deck in position.

Abstract: A method for fabricating on-chip spacers for a TFT panel exposes a photoresist layer on top of the TFT panel using two exposure processes, one through the bottom of the TFT and the other through a mask over the TFT panel. The exposure process through the bottom exposes all photoresist covering windows on the TFT panel and leaves all photoresist corresponding to an opaque grid corresponding a TFT driving circuit. A second exposure process through a mask above the photoresist leaves part of the photoresist in the opaque grid unexposed. The exposed photoresist is removed leaving on-chip spacers only on the opaque grid. Therefore, the on-chip spacers can not affect the display quality and can be easily formed on a high dpi TFT panel.

Abstract: An adjusting device for a tread board of a treadmill has an actuating device, a transmission device and a connecting member. The actuating device is pivotally connected to a bottom of the tread board. The transmission device is connected to the actuating device. The connecting member is connected to the transmission device with a first end and has a second end pivotally attached to the tread board. The connecting member has a middle point pivotally attached to a stand. Accordingly, the actuating device and the transmission device can actuate the connecting member to rotate relative to the stand, and the angle of the tread board relative to the ground is adjusted. Because the transmission device can pivotally rotate relative to the tread board, a large force will not be applied to the transmission device. Consequently, the load bearing of the transmission device is reduced.

Abstract: A treadmill has a stand, a running assembly, a handle assembly and an insulation connecting assembly. The insulation connecting assembly is mounted on the stand to keep the handle assembly from electrically connecting with the running assembly. In such an arrangement, a static electricity free handle assembly is mounted on the treadmill to keep the static electricity from being discharged when the user contacts with the handle assembly.
