Abstract: A way of detecting a watermark present in a structured result, such as a search result or a machine translation. The structured result is received and a hash is computed based upon at least part of the result. The resulting bit sequence is tested against a null hypothesis that the bit sequence was generated by a random variable with a binomial distribution with a parameter p=0.5. The result of this test is compared to a significance level, which indicates whether the structured result is watermarked.

Abstract: A way of generating a watermark for a structured result, such as a search result or a machine translation. A hash function is used to generate a bit sequence for each of a plurality of structured results. A ranking score is generated for each resulting bit sequence. The ranking score can be based on the detectability of the bit sequence compared to a randomly-generated bit sequence and the quality of each of the structured results. A structured result is selected as the watermarked structured result based upon the ranking score.

Abstract: A locking system for locking a container to a vehicle includes a locking assembly mounted to a hoist frame and a striker assembly mounted to the vehicle chassis. The locking assembly has at least one hook for hooking over a frame member of the container. The hook has a center of mass that biases the hook to an unlocked position. The striker assembly strikes the hook at a location to move the hook against the bias of the hook's center of mass into a locked position in which the hook is hooked over the frame member of the container. As the hoist frame supporting the container is lowered, the striker assembly contacts the hook and rotates the hook against the bias of the hook's center of mass into the locked position. As the hoist frame is raised, the hook rises as well and loses contact with the striker assembly, thereby falling away from the hoist frame and unlocking the container.

Abstract: A method of ensuring robust operation of a differential serial link is provided. The method provides a first integrated circuit having 1) a phase generator constructed and arranged to provide a programmable shift of a clock signal based on selective interpolating between first and second phases of the clock signal relative to a digital phase value, and 2) a transmit driver constructed and arranged to control, in a programmable manner, a differential voltage of digital data signals. A second integrated circuit is constructed and arranged to receive the clock and digital data signals sent by the first integrated circuit. The clock and digital data signals are sent substantially simultaneously through the link from the first integrated circuit to the second integrated circuit. It is determined whether the digital data signals can be sampled reliably by the second integrated circuit relative to the digital phase value.

Abstract: A phase selection circuit having a selection circuit, binary weighted current sources, and an amplifier circuit. The phase selection circuit is configured for selecting adjacent phase signals from a number of equally-spaced phases of a clock signal, based on a phase selection value. The selection circuit outputs the adjacent phase signals to respective first and second binary weighted current sources, along with a digital interpolation value. The first current source outputs a contribution current onto a summing node based on the first adjacent phase signal and the digital interpolation control value, and the second current source outputs a second contribution current to the summing node based on the second adjacent phase signal and an inverse of the digital interpolation control value, resulting in an interpolated signal. An amplifier circuit outputs the interpolated signal as a phase-interpolated clock signal according to the phase selection value.

Abstract: An integrated device (e.g., an integrated PCI bridge device) buffers received PCI bus strobe signals and distributes strobe signals for PCI receive data relative to the PCI data lines, enabling all PCI receive data to be latched using locally-generated PCI strobe signals generated based on the same PCI bus strobe signals. In addition, data line latch modules having primary and secondary flip-flops enable the PCI receive data to be held for an entire clock cycle, optimizing conversion between a PCI clock domain and a local clock domain of the PCI bridge device. A transmission circuit also can be configured to transmit data according to either double data rate (DDR) mode or quad data rate (QDR) mode in an efficient manner.

Abstract: A phase alignment circuit having a phase selection circuit, a synchronizer, and a counter form a feedback loop for aligning a local clock signal with a received reference clock of a synchronous communications system. The phase selection circuit is configured for outputting the local clock signal as a phase-adjusted local clock having a selected phase based on a phase selection value specified by the counter. The synchronizer is configured for digitally sampling the received reference clock relative to the phase-adjusted local clock, and outputting a digital phase bit identifying whether the phase-adjusted local clock has a later phase relative to the received reference clock. The counter selectively increments or decrements a counted value based on the digital phase bit, and outputs to the phase selection circuit a prescribed number of most significant bits from the counted value as the phase selection value.
