Method for order selection in passive transmission line macromodels based on the lie criteria
A passive macromodel for lossy, dispersive multiconductor transmission lines uses a multiplicative approximation of the matrix exponential known as the Lie product. The circuit implementation of the macromodel is a cascade of elementary cells, each cell being the combination of a pure delay element and a lumped circuit representing the transmission line losses.

Mode change control system for hybrid vehcile
During vehicle drive under an EV mode, a battery charge state SOC becomes smaller than a SOC(L) at time t0. As a result, EV→HEV mode change is carried out. After time t1, deceleration is desired, and an accelerator opening APO is kept at 0. At time t3, the SOC increases and becomes greater than or equal to a SOC(H) by the HEV mode. In this case, after time t1 of release of an accelerator pedal, the SOC(H) is cleared at time t2 at which a vehicle operating condition is judged to be a low load drive condition in which a motor/generator performs regenerative braking. By making a judgment of HEV→EV mode change based on the SOC(L) instead of the SOC(H), the HEV→EV mode change is carried out before time t3.

Systems and methods with error resilience in enhancement layer bitstream of scalable video coding
A scalable layered video coding scheme that encodes video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video, adds error resilience to the enhancement layer. Unique resynchronization marks are inserted into the enhancement layer bitstream in headers associated with each video packet, headers associated with each bit plane, and headers associated with each video-of-plane (VOP) segment. Following transmission of the enhancement layer bitstream, the decoder tries to detect errors in the packets. Upon detection, the decoder seeks forward in the bitstream for the next known resynchronization mark. Once this mark is found, the decoder is able to begin decoding the next video packet. With the addition of many resynchronization marks within each frame, the decoder can recover very quickly and with minimal data loss in the event of a packet loss or channel error in the received enhancement layer bitstream. The video coding scheme also facilitates redundant encoding of header information from the higher-level VOP header down into lower level bit plane headers and video packet headers. Header extension codes are added to the bit plane and video packet headers to identify whether the redundant data is included. |

Positioning a multipath search window
Multipath components of a signal transmitted through a time-varying digital radio channel are received with individual delays (τ) within a range (τ1 . . . τM) of possible delay values. The individual delays are estimated and a delay profile (g(τi)) calculated repetitively. The method comprises searching repetitively for new multipath components in a search window constituting a subset of the possible delays, and positioning the search window based on a previous delay profile (g(τi)). For each of a number of search window positions (k) a sum of power is determined for the multipath components located in the search window with that position, and the position of the search window is selected based on the determined sums of power. In this way the multipath detection is less influenced by the noise floor, and it is also effective for channels having a wide delay spread and/or significantly time-varying delay profiles. |

MMPP analysis of network traffic using a transition window
Data communication in network traffic is modeled in real time and is analyzed using a 2-state Markov modified Poissen process (MMPP). The traffic inter-arrival times for bursty and idle states define a transition window [λ1max, λ2min] represented by the boundary values λ1max for the inter-arrival time for bursty traffic, and λ2min for the inter-arrival time for idle traffic. Changes in the values of λ1max and λ2min are tracked over time, and the size of the transition window is enlarged or decreased based upon relative changes in these values. If the inter-rival times for the bursty state and the idle state become approximately equal, the model defaults to a single state model. The modeling is applicable to the synchronization of polling and blocking in a low-latency network system. This permits the adoptive selection of poll or block to maximize CPU utilization and interrupt latency. |

The span ID occupies fewer bits in the commands than bits representing a combination of the source node ID and the destination node ID. Alternatively, the commands specify a destination node ID without a span ID or a source node ID, or the commands specify a source node ID without a span ID or a destination node ID. |

Beam irradiation apparatus
An attachment lens is arranged in a stage subsequent to a scanning lens. After a laser beam is converged by the scanning lens, the laser beam is converted into a parallel beam by the attachment lens. When the scanning lens is displaced in a direction perpendicular to an optical axis of the laser beam, a traveling direction of the laser beam is bent by a predetermined angle immediately after the laser beam passes through the scanning lens. Then, the traveling direction of the laser beam is further bent by a predetermined angle in the same direction by the passage of the laser beam through the attachment lens. Accordingly, a final swing angle of the laser beam outgoing from an outgoing window is increased by a swing angle imparted by the attachment lens compared with the case where the attachment lens is not arranged. One of lens surfaces of the attachment lens is formed in a toroidal surface, which allows the laser beam to have a long outline in a vertical direction. |
