摘要:
An anti-fouling composition which comprises a cured or cross-linked polymer free of perfluoropolyether moieties and a fluid fluorinated alkyl- or alkoxy-containing polymer or oligomer. Preferably, the fluorinated alkyl- or alkoxy-containing polymer or oligomer comprises a repeating unit of the general formula: —{[CFR—(CFR)m—(O)n]p—[CFR—O]q}— wherein n is 0 or 1, m is an integer from 0 to 4, R independently is H, F, Cl, Br, or CF3, and the ratio q/p is 0-10, and the fluorine-free polymer is an organosiloxane-containing polymer comprising a repeating unit of the general structure —[SiR1R2—O]—, wherein R1 and R2 are independently hydrogen, alkyl, aryl, aralkyl, or a vinyl group.

A system and method are disclosed for monitoring, managing and reporting credit card prepayment risk for an issuing bank. Sales data, corresponding payment data and data indicating the fulfillment of orders are monitored. The amount required as security by the bank is dynamically adjusted, for example on a daily basis, in response to the quantum of prepayment exposure determined by the data.

Method and apparatus for storing data in a reduced redundancy form. Binary Large Objects (BLOBs) are partitioned into subblocks according to a partitioning method, and the subblocks are stored in subblock clusters. Each BLOB is represented as a list of spans of subblocks which identifies a contiguous sequence of subblocks within a cluster. Storage redundancy can be reduced because the spans of two different BLOBs can refer to the same subblocks. An index may be used to map subblock hashes to subblock cluster numbers.

There is provided an antenna for use in an ultra-wideband device, wherein the antenna is used as an RF radiator and as a heat sink. There is also provided a device for use in an ultra wideband network, the device comprising a component, for example an integrated circuit package, that generates unwanted heat as part of its normal operation, the device further comprising an antenna as described above placed in thermal contact with the component. The antenna may be electrically connected to one or more pins of the component. Alternatively, the antenna may be capacitively connected to the component. There is also provided a heat sink for a wireless communications device, the heat sink being shaped such that it can operate as an antenna for radio frequencies.

The braking mechanism comprises a toggle lever, a brake pad, and an incline. An incline actuates the braking mechanism by forcing an extension of the toggle lever. As the toggle lever extends, it pushes the brake pad closer to the surface to be slowed. Multiple toggle levers may be used to distribute the force across the brake pad. This configuration allows a single input from the incline to actuate both toggle levers. By adjusting the width of the incline actuating the toggle lever, the force on the brake pad may be adjusted.

A feeding bottle (10) comprises a container (12) having a threaded neck (22) around an opening of the container, a teat (16), and, a threaded annular collar. The teat has a flange (84), adapted to seat on said neck, a nipple (88), remote from the flange, and a one-way valve (110) formed in a depression (112) in the teat to allow the passage of air into the container but prevent leakage of liquid from the container through the valve. The collar is adapted to receive the teat through the aperture (56) of the collar. The depression (112) is provided with an upstanding flange (114) above the surface of the teat where the depression (112) joins a main surface of the teat, which flange (114) serves to protect the depression (112) against deformation of the main surface of the teat.
摘要:
This application concerns determining whether a particular subblock of data is present in a reduced-redundancy storage system. One embodiment achieves this by hashing subblocks in the storage system into a bitfilter that contains ‘1’ bit for each position to which at least one subblock hashes. This bitfilter provides a fast way to determine whether a subblock is in the storage system. In another embodiment, index entries for new subblocks may be buffered in a subblock index write buffer to convert a large number of random access read and write operations into a single sequential read and a single sequential write operation. The combination of the bitfilter and the write buffer yields a reduced-redundancy storage system that uses significantly less high speed random access memory than other systems that store the entire subblock index in memory.

There is provided an antenna arrangement for use in an ultra-wideband network, the antenna arrangement comprising a plurality of active elements for emitting radio signals; and a reflecting structure disposed between at least two of the active elements for reflecting radio signals, the reflecting structure comprising an outer reflecting surface for reflecting radio signals in a first frequency range within a frequency band and an inner reflecting surface for reflecting radio signals having a second frequency range within the frequency band. In an alternative embodiment, the antenna arrangement comprises an active element for emitting radio signals, and a reflecting structure. The reflecting structure comprises a first surface for reflecting radio signals having a first frequency range within a frequency band, the first surface being substantially transparent to radio signals outside the first frequency range, and a second surface for reflecting radio signals passed by the first surface, the second surface reflecting radio signals having a second frequency range within the frequency band.
