Abstract: A power-retractable step assembly for a motor vehicle comprises a substantially sealed housing assembly (12), a pivoting structure (14) including a step structure, a gear assembly, and a motor assembly (18). The step structure presents an upper load carrying surface, and the pivoting structure is mounted for pivotal movement about an axis. The gear assembly is disposed in the sealed housing assembly and coupled to the pivoting structure. The motor assembly is drivingly coupled with the gear assembly and is constructed and arranged to pivot the pivoting structure about the axis and thereby drive the pivoting structure between deployed and stored positions. The step structure is moved in an outboard vehicle direction when the pivoting structure is moved from the stored position to the deployed position, and is also moved in a for-aft vehicle direction when the pivoting structure is moved between the stored and deployed positions. The axis is disposed at an angle such that, as the axis extends upwardly, i) the axis extends in the outboard vehicle direction and ii) the axis extends in a same fore-aft vehicle direction as the fore-aft direction that the step structure moves when the pivoting structure is moved from the stored position to the deployed position.

Abstract: A tree harvester for continuously cutting and accumulating trees and a method for using such a harvester is disclosed. The harvester has a frame with a cutting area and a large elongate accumulation area. A tree severing device is secured to one end of the frame and a continuous rail having accumulating arms secured to its extends from the cutting area to the rear portion of the accumulation area. The arms are equally spaced apart from each other along the rail, with each arm traveling in a continuous circuit along the rail such that it moves from the cutting area to the accumulation area. During use, the harvester is aligned with a row of trees to be cut. As the first tree is cut by the severing device, an accumulating arm is positioned behind the tree and moves it to the rear most available portion of the accumulation area. As the harvester travels down the row of trees, each tree in the row is cut and moved to the rear most available portion of the accumulation area. In a preferred embodiment, the harvester is self-propelled, has a curfless cutter, and travels forward along the row of trees to be cut at the same speed as the arms travel around the circuit.

Abstract: This invention relates to a transmission power control method and transmission power control apparatus in a mobile communication system. The reception quality of a signal (31, 32a, 32b, 41, or 42) transmitted from another mobile station (51 or 52) or base station (21 or 22) is compared with a predetermined control target value such as a signal-to-interference ratio. The comparison result is used for transmission power control on a remote station.  If a frame error is detected in a transmitted signal, the control target value is increased by SIRinc. If no frame error is detected, the control target value is decreased by SIRdec. As SIRdec, the product of a target value of a frame error rate and SIRinc is set. With this operation, when a propagation environment such as multibus or moving speed changes, the control target value for transmission power control is changed within a short period of time, and channel quality is maintained constant, thus realizing desired channel quality.

Title: Default route coding
Inventor: BROWN DAVID A
IPC: G06F15/173
Filed: 2001-12-17
Granted: 2011-04-12
Abstract: A multi-level lookup table includes a plurality of search levels with each search level including a plurality of subtrees, each subtree representing a plurality of nodes. A search of the multi-level lookup table for an entry corresponding to a search key results in a value stored in an entry associated with the node in a subtree. A default value is associated with the root of the subtree. Multiple entries for the subtree can store the default value. To minimize route update time, the default value associated with the subtree is stored in a single location. Instead of storing the default value in multiple entries, each entry stores a use default indicator to indicate that the default value stored in the single location is to be used. To further reduce the number of locations to modify to update the default route, the single location can store an inherit indicator to indicate that the default value for the subtree is inherited from another subtree.

Abstract: This invention provides a novel wavelength-separating-routing (WSR) apparatus that uses a diffraction grating (101) to separate a multi-wavelength optical signal by wavelength into multiple spectral channels, which are than focused onto an array of corresponding channel micromirrors (220). The channel micromirrors are individually controllable and continuously pivotable to reflect the spectral channels into multiple output ports. As such, the inventive WSR apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. The WSR apparatus of the present invention may be further equipped with servo-control and spectral power-management capabilities, thereby maintaining the coupling efficiencies of the spectral channels into the output ports at desired values. The WSR apparatus of the present invention can be used to construct a novel class of dynamically reconfigurable optical add-drop multiplexers (OADMs) for wavelength division multiplexing (WDM) optical networking applications.
