The present disclosure relates receiving a plurality of Protocol Data Units (PDU) of a PDU sequence over a radio interface; detecting that a PDU of the sequence of the received PDUs is missing, wherein for each of the received PDUs, identifying which Service Data Unit(s) (SDU) it relates to; based on said identifying, determining that a complete SDU is obtainable from one or several PDUs of the received PDUs, which one or several PDUs are later in the sequence of the received PDUs than the missing PDU; obtaining the complete SDU from said one or several PDUs; performing a packet inspection of the obtained complete SDU to determine the type of data it carries; and based on the performed packet inspection, determining that the complete SDU fulfils a predetermined criterion; and delivering the complete SDU before receiving a retransmission of the PDU which is missing.

It is disclosed a mixer arrangement for complex signal mixing comprising a first harmonic rejection mixer, and a second harmonic rejection mixer. Each of the harmonic rejection mixers comprises mixer unit cells wherein each mixer unit cell comprises a differential input, transconductance elements corresponding to the differential input, and a switching network arranged to switch signals from the transconductance elements to a differential output, and the first and the second harmonic rejection mixers have mutual quadrature phase relationship. The first and the second rejection mixer share a plurality of mixer unit cell, each comprising an input for receiving a signal to be mixed, an input for receiving control signals derived from a local oscillator signal, and one output for each of the first and second harmonic rejection mixers. A radio circuit comprising such a mixer arrangement and a communication apparatus comprising such a radio circuit are also disclosed.

There is disclosed means for uploading/downloading images to/from a remote server and for viewing the same. The uploading/downloading of the images to/from the remote server is parallel instead of serial. This means that the images, instead of being transferred as a sequential stream of bytes, instead are arranged in scans of image data in such a way that the uploaded/downloaded images can be browsed early albeit at a lower quality than if the entire image data is considered. As in the serial case, it is possible to interrupt the uploading/downloading process at any time, and still browse the received image data. Likewise it is possible to re-start the uploading/downloading process in the future.

Progressive multimedia synchronization

A method and apparatus taught herein provide a digital-to-analog converter (DAC) for use in a conversion feedback path of a sigma-delta type analog-to-digital converter (ADC). The DAC uses current pulse shaping to generate a conversion feedback signal in each feedback cycle of the ADC that provides a consistent charge transfer for accurate digital conversion and has a controlled current pulse shape. In one or more embodiments, the DAC includes a capacitor circuit for charge storage and transfer and a (series) resistive circuit having variable resistance for current pulse shape control. In at least one embodiment, current pulse control limits a peak current of the conversion feedback signal, thereby reducing DC power consumption and gain-bandwidth (GBW) and slew rate requirements of the ADC's integration amplifier, and limiting residual (ending) current in each feedback cycle, which yields commensurate gains in (feedback cycle) clock jitter insensitivity.

Use of a compound having a hydrophobic moiety attached to a hydrophilic moiety, wherein the hydrophilic moiety comprises a &#x3b2;-keto acid group and the hydrophobic moiety is attached via a bond from a carbon or an oxygen of the hydrophobic moiety to a carbon of the &#x3b2;-keto acid group, provided that the &#x3b2;-carbon of the &#x3b2;-keto acid group does not form part of a carboxyl or ester group, or a salt thereof, as a surfactant. A dispersion comprising said surfactant as a dispersing agent. A method for breaking a dispersion comprising said surfactant as a dispersing agent, said method comprising the steps of a) providing said dispersion at a temperature where it is substantially stable; and b) setting the temperature of said dispersion, so as to achieve a desired decomposition rate of the surfactant.
