Abstract: A method for transferring data from a database may include receiving, at a database management system, a request to transfer, to a client, at least a portion of data stored at a database coupled with the database management system. The database management system may respond to the request by at least generating an internal table containing at least the portion of the data being transferred to the client. The database management system may further transfer at least the portion of the data to the client by at least sending, to the client, one or more data chunks. Each of the one or more data chunks may include at least a portion of a column of data from the internal table. Related systems and articles of manufacture, including computer program products, are also provided.

Abstract: A filter assembly for a dryer appliance is provided. The filter assembly includes a filter medium rotatably mounted within a filter cassette that is removably received within a filter slot of the dryer appliance. The filter medium has a first portion and a second portion that are selectively exposed to a stream of exhaust air from the dryer appliance to extract lint. While one portion is filtering lint, a lint removal system removes the lint from the other portion collected during the prior cycle. After each cycle, a motor is configured for rotating the filter medium to expose the clean portion of the filter. The filter cassette is removably received within the filter slot using a magnetic latching mechanism, a securing cover, or another suitable mechanism. A scrubber mechanism may also be used to remove stubborn lint.

The lift assembly includes a gear assembly that includes an output spur gear and an input drive gear, and includes a first arm extending between a first end and a second end, the first end of the first arm pivotally coupled to the lower rack, the second end of the first arm coupled to the output spur gear. Movement of the input drive gear causes movement of the lower rack along the transverse direction between a retracted position wherein the lower rack is within the wash chamber and an extended position wherein the lower rack is positioned outside of the wash chamber and along the vertical direction between a lowered position and a raised position wherein the raised position is above the lowered position along the vertical direction.

Abstract: Dryer appliances and methods are provided. A method includes receiving during rotation of a drum of the dryer appliance a voltage signal which corresponds to a moisture level within a chamber of the drum, and determining whether the voltage signal corresponds to a predetermined drying profile of a plurality of predetermined drying profiles. The method further includes applying a drying sequence which corresponds to one of the plurality of predetermined drying profiles when the voltage signal corresponds to the one of the plurality of predetermined drying profiles. The method further includes determining whether the voltage signal corresponds to a wet patch indicator, and reversing a direction of rotation of the drum when the voltage signal corresponds to the wet patch indicator.

Abstract: A lower rack assembly for a dishwasher appliance includes a lower rack configured for receipt of articles for washing, and a lift assembly connected to the lower rack. The lift assembly includes a first arm extending between a first end and a second end, the first end of the first arm pivotally coupled to the lower rack, and a first bracket defining a first slot, the second end of the first arm movably coupled to the first slot. Movement of the lower rack along the vertical direction causes movement of the second end of the first arm relative to the first slot along the transverse direction and pivotal rotation of the first end of the first arm.

Abstract: Systems and methods for determining an out of balance condition of a washing machine are provided. In particular, a plurality of angular positions of a motor associated with a washing machine can be determined. The washing machine can include a wash tub, and a wash basket rotatably mounted within the wash tub. The motor is configured to rotate the wash basket within said wash tub. Data indicative of at least a single phase of motor current being applied to the motor can be obtained while the wash basket rotates. The data can be spatially sampled over at least a subset of the plurality of angular positions of the motor. An out of balance condition associated with the washing machine can be determined based at least in part on the sampled data.
