| 20080302394 | BRUSH AND METHODS OF CLEANING A BRUSH - A brush includes a body and a cleaning element. The body includes a plurality of bristles extending outward from said body. The cleaning element is slidably coupled to the body, and includes at least one projection and a retaining element. The at least one projection is substantially radially aligned with the plurality of bristles for engaging the plurality of bristles as the cleaning element is translated longitudinally across the body. The retaining element facilitates limiting circumferential movement of the plurality of bristles as the cleaning element is translated across the body. | 12-11-2008 |

| 20110000378 | DISPOSABLE BREW BASKET FOR ELECTRIC COFFEE MAKER - An apparatus for use in a beverage brewing machine includes a filter pack containing an amount of grinds to brew approximately only a single serving of brewed beverage, a single serving disposable brew basket including a body defining a brewing reservoir. The body is formed with a disposable rigid construction. The body has an opening therethrough to permit a brewed beverage to flow from the brewing reservoir of the disposable brew basket into a beverage container. The body extends upwardly from a bottom of the brewing reservoir to an open top that is configured to receive heated water from the brewing machine. The heated water flows through the open top during a brewing operation. The brewing reservoir has a size dimensioned appropriate to make approximately only a single serving of beverage during a single brewing operation. The brewing area is sufficiently large to hold the filter pack and the heated water while brewing without a level of the heated water rising above and overflowing the open top. | 01-06-2011 |

| 20110033242 | MODULAR-UNIT FLOODWALL SYSTEM - A modular-unit floodwall system is disclosed. The system includes modular floodwall units configured for holding water and connecting and sealing devices for connecting the units together to form a barrier against floodwater. A method of constructing such a floodwall is also disclosed. | 02-10-2011 |

| 20110204799 | Current driver for LED - A current driver for powering an LED assembly comprises an input capacitor and a full wave rectifier. The LED assembly is connected to the rectifier output terminals. A driven LED assembly may be formed of series and parallel strings of individual LEDs. AC Line frequencies, e.g., 50 cycles, 60 cycles, non-line AC frequencies; and ranges of source voltages, e.g., 120 to 220 volts are accommodated by the driver. The driver provides essentially equal energy current pulses to the LED load, coincident with the time and the duration of the positive excursions of the input power. Energy is delivered to the LED load in a 50% duty cycle. Transfer of energy from an AC input power source to an LED assembly is independent of the output parameters of that source. | 08-25-2011 |

| 20090298399 | SEMICONDUCTOR WAFER POLISHING APPARATUS AND METHOD OF POLISHING - A wafer polishing apparatus has a base and a turntable having a polishing pad thereon and mounted on the base for rotation of the turntable and polishing pad relative to the base about an axis perpendicular to the turntable and polishing pad. The polishing pad includes a work surface engageable with a front surface of a wafer for polishing the front surface of the wafer. A drive mechanism is mounted on the base for imparting rotational motion about an axis substantially parallel to the axis of the turntable. A polishing head is connected to the drive mechanism for driving rotation of the polishing head. The polishing head has a pressure plate adapted to hold the wafer for engaging the front surface of the wafer with the work surface of the polishing pad. The pressure plate has a generally planar position and is selectively movable from the planar position to a convex position and to a concave position. | 12-03-2009 |
