Abstract: An LED display panel structure comprises a PC board, a front plate having a plurality of through-holes defined thereon, a plurality of washers, each of which is provided on a back surface of the front plate in correspondence with each of the through-holes, a plurality of LEDs, each of which is inserted through a central aperture of each of the washers being smaller than a diameter of the LED to be clamped therein, and a plurality of holders, each of which has a first recess and a second recess, each of the holders receives and holds each of the LEDs in its first recess and is attached on the PC board by water resistant adhesive filled in the second recess. A pair of through-bores communicating the first recess with the second recess are defined therebetween to allow a pair of leads of each of the LEDs to extend therethrough and connect to the PC board. Such a structure can prevent moisture from seeping in to damage the LEDs.

Abstract: A method and system for playing a lottery type game includes a gaming piece which includes a predetermined code having data indicating whether the player wins or loses the game, the data being unrecognizable to the player, such that the player does not know the outcome of the game prior to play of the game. The code is stored on the gaming piece in a memory device. The gaming piece is reusable with different codes. The code is read by a processor. The processor presents an amusement game on a display for play by the player, and the player controls game play by inputting game parameters to the processor. The processor controls the outcome of the amusement game played by the player based upon the code. A display provides an indication to the player of a game win or a game loss based upon the code.

Abstract: A handle assembly includes a supporting bracket fixedly mounted on a top wall of a suitcase and including a base plate having two end portions each with a socket defined therein, and a side extension wall extending downwardly from one side of the base plate. Two receiving casings are each fixedly mounted on the side extension wall and each communicate with a corresponding socket. Two catches each formed on the side extension are each located in a corresponding casing. Two rotary drums are each rotatably received in a corresponding receiving casing and each have a plurality of teeth formed on an outer periphery thereof and each meshing with an associated catch.

Abstract: A gas flow control device for injecting gas into a production string for recovering pressure and reducing frictional losses, so that critical flow can be reached at lower pressure drops and higher production pressure, includes a nozzle having first and second ends, and a flow path therebetween, and a Venturi having first and second ends, and a flow path therebetween. The first end of the Venturi portion is disposed adjacent to the second end of the nozzle. The Venturi flow path coaxially aligned with the nozzle flow path to provide a continuous flow path through the valve. A method to increase the production rate, improve the lift efficiency, and eliminate or suppress instability in continuous-flow gas lift wells by use of a flow control device that has a gas flow rate performance that is independent of the tubing pressure even when the tubing pressure is as high as 80% to 93% of the casing pressure.

Abstract: A stepping exerciser includes a base frame having a first end portion, a second end portion, a first side wall, and a second side wall. A supporting handle has a lower end portion mounted on the first end portion of the base frame in an inclined manner, and an upper end portion with a handgrip mounted thereon. A driving axle is rotatably mounted on the second end portion of the base frame and has a first end and a second end extending through the first and the second side wall of the base frame respectively. A first stepping member has a mediate portion fixedly mounted on the first end of the driving axle. A second stepping member is disposed in an inclined manner with the first stepping member and has a mediate portion fixedly mounted on the second end of the driving axle. A tension adjusting mechanism is mounted in the base frame and is engaged with the driving axle for damping a rotation of the driving axle.

Abstract: A retractable handle assembly includes a supporting bracket fixedly mounted on a top wall of a suitcase and including two end portions each having a socket vertically defined therein and a side extension wall extending downwardly from an underside thereof. Two receiving casings are each fixedly mounted on the side extension wall of the supporting bracket and each communicate with each of the two sockets. Two rotary cylinders are each rotatably received in a corresponding one of the two receiving casings and each have a passage radially defined therein and aligning with an associated socket. A U-shaped handle includes two upright legs each movably mounted on the supporting bracket and each slidably extending through a corresponding one of the two sockets and an associated passage. A handgrip has two distal ends each having a sleeve extending downwardly therefrom and fixedly mounted on an upper end of a corresponding one of the two upright legs.

Abstract: A docking adapter includes a male HDI 30 type connector (for connecting to a "POWERBOOK" portable computer) and a female DB 25 type connector (for connecting via a SCSI bus cable to either a "MACINTOSH" personal computer or a SCSI external hard drive). The pins of the HDI type connector are electrically connected to the corresponding pins of the DB type connector. The adapter includes a switch having an actuated position for grounding pin 1 of the HDI type connector to "dock" the portable computer in a disk operating mode facilitating data transfer with the "MACINTOSH" over the SCSI bus. When not in the actuated position, the portable computer may be connected to and access the external hard drive over the SCSI bus. The adapter also includes a light emitting diode (LED) connected between the termination power pins of the DB and HDI connectors and ground to monitor for the presence of termination power on the SCSI bus.
