Abstract: The disclosure relate to determining a realism metric for testing software for operating a vehicle in an autonomous driving mode. For instance, a plurality of versions of a simulation may be run using log data collected by a vehicle operating in an autonomous driving mode. The plurality of versions may be run using the software to control a simulated vehicle, and each of the plurality of versions may have a set of timing requirements different from the set of timing requirements of other of the plurality of versions. Results of the plurality of versions may be compared to the log data. A realism metric defining timing requirements for one or more future simulations may be generated based on the comparison.

Abstract: A heat-assisted magnetic recording device includes a write pole positionable adjacent a magnetic recording medium and configured to write data to the medium. A near-field transducer is situated proximate the write pole and configured to produce a thermal spot on the medium. A channel circuit is configured to generate a sequence of symbols having a length of nT, where T is a channel clock rate and n is an integer over a predetermined range. A write driver is configured to apply bi-directional write currents to the write pole to record the sequence of symbols at a location of the thermal spot on the medium, wherein a duration of applying the write currents to the write pole by the write driver is dependent on a length of the sequence of symbols and the effective thermal spot size.

Abstract: An apparatus comprising a liquid crystal material and a controller are described herein. The liquid crystal material is disposed between a first electrode and a second electrode opposite the first electrode. Molecules of the liquid crystal material assume a first orientation during a first state of the liquid crystal material and a second orientation during a second state of the liquid crystal material. The first orientation is different from the second orientation. The controller is coupled to the first electrode and the second electrode to perform operations. The operations include applying a first periodic waveform to the first electrode and a second periodic waveform to the second electrode to generate a drive waveform applied across the liquid crystal material. The operations further include changing a duty cycle of the drive waveform over a first time period to transition the liquid crystal material between the first state and the second state.

Abstract: A higher coding efficiency for coding a significance map indicating positions of significant transform coefficients within a transform coefficient block is achieved by the scan order by which the sequentially extracted syntax elements indicating, for associated positions within the transform coefficient block, as to whether at the respective position a significant or insignificant transform coefficient is situated, are sequentially associated to the positions of the transform coefficient block, among the positions of the transform coefficient block depends on the positions of the significant transform coefficients indicated by previously associated syntax elements. Alternatively, the first-type elements may be context-adaptively entropy decoded using contexts which are individually selected for each of the syntax elements dependent on a number of significant transform coefficients in a neighborhood of the respective syntax element, indicated as being significant by any of the preceding syntax elements.

The system performs a device discovery process to determine with Power Supply Units are connected to which Remote Radio Heads on the tower. It also provides several ways of characterizing the power cables and input capacitance to the Remote Radio Heads to provide optimal power to the Remote Radio Heads, including situations in which the power demand for the Remote Radio Heads increases, while obviating the need to replace the power cables with those of greater current capacity. Further, the system provides for stable power even in the presence of sensor instabilities and data dropouts.

Abstract: Apparatus and methods for physical cell identification within one or more wireless networks. In one embodiment, conflicts in PCI values which may exist within two or more mobile networks (e.g., PLMNs) of respective different operators when unlicensed spectrum is utilized (e.g., according to 3GPP 5G NR-U technology) are resolved. In one implementation, this functionality is provided by specifying one or more mobility-related parameters associated with various UE, such that serving gNBs can determine whether a given UE requires a mobility context, and as such whether it should conduct subsequent RF measurement reporting to report back potential conflicts in PCI it may encounter to the gNB. In one variant, the measurement reporting is configured to comply with 5G NR-U required “listen-before-talk” or LBT protocols; i.e., to measure parameters consistent with the LBT protocols to detect any such PCI-based conflicts.

Abstract: The brain appears to have organized cardiac frequency angiographic phenomena with such coherence as to qualify as vascular pulse waves. Separate arterial and venous vascular pulse waves may be resolved. This disclosure states the method of extracting a spatiotemporal reconstruction of the cardiac frequency phenomena present in an angiogram obtained at faster than cardiac frequency. A wavelet transform is applied to each of the pixel-wise time signals of the angiogram. If there is motion alias then instead a high frequency resolution wavelet transform of the overall angiographic time intensity curve is cross-correlated to high temporal resolution wavelet transforms of the pixel-wise time signals. The result is filtered for cardiac wavelet scale then pixel-wise inverse wavelet transformed. This gives a complex-valued spatiotemporal grid of cardiac frequency angiographic phenomena. It may be rendered with a brightness-hue color model or subjected to further analysis.
