Abstract: A method and system for distributed messaging between a plurality of computer devices using a short range wireless communication protocol (SRWP) is disclosed. The communication protocol can be one in which slave devices provide data to master devices. A device automatically establishes master and slave connections with other devices via the protocol as they come into range. A user-entered message is displayed on the device and broadcast by the device over slave connections to other connected devices. Messages received by the device over its master connections are displayed and also rebroadcast to other connected devices. Messages can be displayed for a limited time period during which they fade or otherwise are altered to provide a visual indication of the display lifetime remaining for that message. A relay can be provided to receive an rebroadcast messages to connected devices and inject into the SRWP network from devices outside the network.

Abstract: A roller partition wall comprises a ceiling bracket, a floor bracket, a partition wall, and a plurality of rollers. A bottom surface of the ceiling bracket forms a first sliding slot, a top surface of the floor bracket forms a second sliding slot corresponding to the first sliding slot, a top surface and a bottom surface of the partition wall are respectively inserted into the first sliding slot and the second sliding slot, and the partition wall is capable of movably disposing between the first sliding slot and the second sliding slot. The rollers are disposed in the second sliding slot and are between the partition wall and the second sliding slot.

Abstract: A human powered watercraft or land vehicle is described herein. A watercraft or land vehicle may have two pedals that reciprocated are in a linear or slightly curved trajectory but not a circular motion. As the two pedals are reciprocated, an output shaft is rotated in either a clockwise or counterclockwise direction when the left pedal is pushed forward or when the right pedal is pushed forward. The output shaft may be connected to a propeller of a watercraft or a land vehicle so as to propel the watercraft or land vehicle forward. The output shaft may receive rotational input through two gears mounted to the output shaft with one-way bearings that enable the output shaft to rotate in the same direction regardless of whether the left pedal or the right pedal is being pushed forward.

Abstract: A lower electrode plate receives radiofrequency power. A first upper plate is positioned parallel to and spaced apart from the lower electrode plate. A grounded second upper plate is positioned next to the first upper plate. A dielectric support provides support of a workpiece within a region between the lower electrode plate and the first upper plate. A purge gas is supplied at a central location of the first upper plate. A process gas is supplied to a periphery of the first upper plate. The dielectric support positions the workpiece proximate and parallel to the first upper plate, such that the purge gas flows over a top surface of the workpiece so as to prevent the process gas from flowing over the top surface of the workpiece, and so as to cause the process gas to flow around a peripheral edge of the workpiece and below the workpiece.
