Abstract: A drum washing machine, and a control method and a control apparatus for same are provided. The control method for the drum washing machine comprises the following steps: acquiring an average starting power of a drum in a starting process of the drum; acquiring a load range to which a current load of the drum belongs according to the average starting power; and setting a weighing protection velocity fluctuation threshold according to the load range to which the current load of the drum belongs. A value of the current load is obtained by using a correspondence between load with different weights and average starting powers. A weighing protection velocity fluctuation threshold is set according to the value of the current load to avoid the collision with the drum and non-dehydration in case of only one piece of clothing.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for channel bonding in an adaptive coding and modulation mode. In some implementations, a system receives packets of a data stream for transmission in a satellite communications system. The system determines a modulation and coding arrangement for the received packets. The system generates code blocks that include data from the packets of the data stream. The system assigns the generated code blocks for transmission on different carriers. One or more of the different carriers is operated in an adaptive coding and modulation mode to support multiple modulation and coding arrangements within a single carrier. The system transmits the code blocks on the different carriers using the determined one or more modulation and coding arrangements.

Abstract: A very small aperture terminal (VSAT) installation tool is provided having the ability to measure cable loss along an interfacility link (IFL) between an outdoor unit and an indoor unit of the VSAT. Radio frequency (RF) signals can be transmitted from the indoor unit to the outdoor unit, where the RF signals are intercepted along the IFL prior to reaching the outdoor unit, and the output power is determined. The determined output power is compared to an expected output power at the indoor unit. The delta between the determined output power and the expected output power can be used to adjust the power of the indoor unit such that the outdoor unit can operate without reaching its compression point. The determined output power can be extrapolated based upon measured of the output power performed over a range of frequencies at which the indoor unit operates.

Abstract: A receiver is used with third code blocks based on first code blocks, second code blocks, and a planning code block. The first code blocks are associated with a first sequence number and modulated with a first modulation scheme. The second code blocks are associated with a second sequence number and modulated with a second modulation scheme. The planning code block associates the third code blocks with the first code blocks and the second code blocks. The receiver includes a de-multiplexing portion, which includes a code block selector and a look up table, that outputs a de-multiplexed signal based on the third code blocks. The code block selector selects a code block from the third code blocks to output as the de-multiplexed signal based on entries in the look up table. The receiver also includes a recovery portion that outputs received code blocks based on the de-multiplexed signal.

Abstract: Systems and methods for performing preprocessing of received data packets, to reduce processing burdens and improve efficiency of communications terminal receivers, are provided. A first stage filter receives a data frame comprising data packets representing respective encapsulated fragments of a PDU. The first stage filter parses a header of one of the packets to locate a start field, and determines whether the start field indicates that the packet comprises a start fragment of the PDU. When the start field indicates that the packet comprises the start fragment, the first stage filter determines, based on packet label information of the packet header, whether to forward the packet to a second stage filter or to discard the packet, and forwards or discards the packet accordingly. When the start field indicates that the packet does not comprise the start fragment, the first stage filter forwards the packet to the second stage filter.
