A folding system is provided for folding at least one wing extending from a central chassis of each of a plurality of absorbent articles formed from a continuous moving web moving in a longitudinal direction. The folding system has a wing-folding conveyor and at least one elongated, folding plow, which has an entrance end, an exit end and an inner edge that define a twist axis. The folding plow has a contoured surface having a configuration defined by a twist angle that increases along the twist axis from zero degrees near the entrance end to 180 degrees near the exit end. The wing-folding conveyor moves the central chassis along the inner edge of the folding plow and the wing slides against the contoured surface from the entrance end to the exit end, such that the wing folds around the central chassis near the inner edge.

The present invention is directed to a washing machine with improvements to the hardware for direct steam injection. One improvement is a steam delivery tube (herein called a sparge tube) that penetrates a side wall above the water level, but releases steam below the water level. One improvement is a steam delivery tube (herein called a sparge tube) that penetrates a rotating side wall above the water level, but releases steam below the water level. Another improvement is the use of a curved sparge tube that can conform within and between the contours of (typically cylindrical) rotating side walls. Another improvement is a sparge tube that releases steam in a direction at least substantially parallel to the central axis of the washing chamber. Another improvement is a temperature probe that penetrates a rotating side wall above the water level, but extends and measures temperature below the water level. A controller controls the open/shut status of steam valve. This controller uses the temperature measured by the temperature probe.

The invention concerns a portable carrying apparatus (100) and a method (800) of the operation thereof. In one arrangement, the portable carrying apparatus can include a holding device (104) and a clip (106). The holding device can be made of a material that is capable of transmitting light. A light source (302) can be activated by an activation device (410) to illuminate the holding device in the occurrence of an event. The method can also include configuring the duration as well as a sequence of illumination of the light source, depending on the event that takes place.

A data communication transmitting node is provided, the transmitting node comprising: a plurality of buffers for storing data from a respective plurality of input data streams; means for monitoring an occupancy level of each of the plurality of buffers to detect if the occupancy level is sufficient to provide a complete data block to the transmission stream; and a transmission controller operable to select, in turn, a buffer from the plurality of buffers to output a data block to a transmission data stream, the selection being performed according to a buffer selection order. If the buffer selected by the transmission controller is detected to have an insufficient occupancy level when selected, a dummy data block is supplied to the data transmission stream in place of a data block from the selected buffer.
摘要:
A data communication system for communicating one or more payload streamed data signals and an auxiliary data signal, the auxiliary data signal being arranged as one or more data packets according to a data packet protocol, each packet having a packet destination address. The system includes at least two data handling nodes, a transmitting one of the data handling nodes arranged to transmit data to a receiving one of the data handling nodes, and a transmission data formatter associated with the transmitting node for formatting the packets of the auxiliary data signal into a streamed data signal format and for multiplexing the payload streamed data signals and the formatted auxiliary data signal into a bitstream for transmission. The system further includes a received data reformatter associated with the receiving node for demultiplexing the input streamed data signals and the formatted auxiliary data signal and for reformatting the auxiliary data signal into packets according to the data packet protocol.

A data communications system for communicating a data signal formed of successive data elements, said system comprising a transmission node; a reception node; and a link providing a data connection from said transmission node to said reception node; in which: said transmission node comprises a clock signal transmitter for transmitting a synchronisation clocking signal to said reception node via said link, said synchronisation clocking signal having synchronising features occurring at a frequency lower than a data element rate; an assembler for assembling elements of said data signal into data frames, each data frame having a plurality of successive data elements of said data signal, for transmission to said reception node via said link, said assembler being responsive to said synchronisation clocking signal so as to set a synchronisation flag associated with a data element having a first predetermined temporal relationship with a synchronising feature of said synchronisation clocking signal; and said reception node comprises: a detector detecting a synchronising feature of said synchronisation clocking signal received from said transmission node; a disassembler for disassembling received data frames to regenerate said data signal, said disassembler being operable to detect a data element associated with a set synchronisation flag; an output unit for outputting a data element associated with a set synchronisation flag at a second predetermined temporal relationship with respect to said synchronising feature of said received synchronisation clocking signal; said first and second predetermined temporal relationships being arranged so that a predetermined system latency exists between input of a data element to said transmission node and subsequent output of that data element by said reception node.
摘要:
A pneumatic actuator comprises a cell through which a normally laminar flow of air passes between an inlet and an outlet to provide, in the outlet, an output pressure. The cell includes an electro-acoustic transducer, for example a piezo-electric element arranged, in response to an oscillating electrical signal, to produce an acoustic signal that disturbs the laminar flow whereby at least some of the air exhausts from the cell via one or more exhaust ports and the output pressure falls. The difference in the output pressures may be used to control a pneumatic device optionally via a pneumatic amplifier. The electrical signal is produced by an opto-electrical transducer to which optical control signals are transmitted, for example along a fibre optic cable.

In order to ensure that the vibrations of a system under test are in accordance with a reference spectral density Z(w), the system is driven by a signal x.sub.n (t) provided by an inverse discrete Fourier transform (IDFT) with random phases introduced by a function R.sub.n (w) and the response spectral density Y.sub.n (w) provided by a DFT is brought into agreement with Z(w) by a feedback loop. Moreover, in order to ensure that this is done in one iteration, X'.sub.n (w) is derived from x.sub.n (t) by a DFT and divided by Y.sub.n (w) and the quotient is multiplied with Z(w) to provide the new input x.sub.n (w) for the IDFT. The division cancels out the random factor which is present in both X'.sub.n (w) and Y.sub.n (w).The system thus equalizes both rapidly and stably.
