Abstract: A Successive Approximation Register, SAR, Analog to Digital Converter, ADC, (50) achieves high speed and accuracy by (1) alternating at least some decisions between sets of comparators having different accuracy and noise characteristics, and (2) unevenly allocating redundancy (in the form of LSBs of range) for successive decisions according to the accuracy/noise of the comparator used for the preceding decision. The redundancy allocation is compensated by the addition of decision cycles. Alternating between different comparators removes the comparator reset time (treset) from the critical path, at least for those decision cycles. The uneven allocation of redundancy—specifically, allocating more redundancy to decision cycles immediately following the use of a lower accuracy/higher noise comparators—compensates for the lower accuracy and prevents the need for larger redundancy (relative to the full-scale range of a decision cycle) later in the ADC process.

Abstract: A unit (25, 46) performs a compression operation or a decompression operation with respect to information for transmission in packets over a wireless link (36). The transmission over the wireless link is such that the packets may become reordered from a transmission sequence. The compression operation and the decompression operation involve a tradeoff of robustness and reordering depth. The robustness is an indicator of a degree of information loss over the link tolerated by the compression operation and the decompression operation; the reordering depth is a degree of packet reordering tolerated by the compression operation and the decompression operation. The unit dynamically adjusts the tradeoff of the robustness and the reordering depth in accordance with characteristics of the link. In an example embodiment, the information upon which the compression operation and the decompression operation is performed is sequence number information of a packet header.

The cover plate has an opening to enable insertion of an object into the cleaning device. The cleaning device further has a first rotatable brush arranged in the housing and having a first axis, and a second rotatable brush arranged in the housing and having a second axis. When an object is inserted through the opening, the object is drawn into the cleaning device in a direction from the opening by means of the rotation of the rotatable brushes.

Abstract: The invention relates to header compression in packet-based communication systems. A mechanism that allows a compressor to reject a request for an undesirable mode change is proposed. The compressor indicates to the decompressor that the mode change request is being ignored, whereafter the decompressor may abort the initiated mode transition, with the understanding that the compressor has valid reasons to refuse it. The compressor preferably determines whether the rejection succeeded by link monitoring, and in case of a successful rejection, the compressor remains in its current mode. A preferred embodiment performs explicit rejection signaling through a mode change rejection message with a redefined mode value. The rejection signaling of the invention makes it possible for a compressor to disable the transition to a particular mode and enables implementations with only a subset of all modes.
