Abstract: An optical network has an optical splitter connected to (1) a working optical subscriber unit (OSU) of a working circuit via a working optical fiber, (2) a protection OSU of a protection circuit via a protection optical fiber, and (3) one or more optical network terminals (ONTs). The present invention enables fast protection switching from the working OSU to the protection OSU. In one embodiment, the arrival times of corresponding upstream ranging reply PLOAM cells are measured at both the working and protection OSUs during ranging operations of the working OSU. In another embodiment, a cell delineation procedure is initiated at the protection OSU during normal, non-ranging operations of the working OSU to enable the protection OSU to correctly delineate upstream cells and the arrival times of corresponding upstream cells are then measured at both the working and protection OSUs. In either case, a propagation delay value is generated based on the measured arrival times for use by the protection OSU  for communications with the one or more ONTs if and when protection switching is implemented upon detection of a failure in the working circuit, possibly without requiring the protection OSU to perform any ranging for the one or more ONTs.

Abstract: The invention relates to a method for improving the coding accuracy and transmission efficiency of an audio signal. According to the method, a part of the audio signal to be coded is compared with earlier stored samples of the audio signal and a reference sequence of samples that best corresponds to th e audio signal to be coded is identified. Predicted signals are produced from the reference sequence by means of long-term prediction, using at least two different LTP orders (M), a group of pitch predictor coefficients (b(K)) bei ng formed for each pitch predictor order. The predicted signals for each pitch predictor order are compared with the audio signal to be coded in order to determine a prediction error. The amount of information required to code the predicted signals is compared with the amount of information required to cod e the original signal and a coding method that provides the best representatio n of the audio signal while minimising the amount of data required is selected .

Abstract: A straddle packer tool for treatment of wells has a tool body supporting sealing elements in spaced relation for defining a sealed annulus zone within a wellbore. The tool body defines a treatment fluid passage having treatment ports that open to the sealed annulus zone for formation fracturing or other well treatment. The tool body has a bypass passage therethrough which is isolated from the treatment fluid passage and communicates with the wellbore above and below the sealed annulus zone. A check valve permits downward flow of well fluid from the bypass passage into the wellbore below the tool and prevents upward flow of fluid into the bypass passage. Bypass ports conduct fluid flow to and from the bypass passage and the wellbore above and below the sealed annulus zone. A packer actuated bypass valve is opened or closed to control the flow of well fluid within the bypass passage.

Abstract: A transportation vehicle (100) for transporting an individual over ground having a surface that may be irregular. The vehicle has a support platform (112) For supporting the subject and the support platform is coupled to a ground-contacting module at a pivot (118). While the ground-contacting module may be statically stable, balance ol the support platform with respect to the ground-contacting module (104) is maintained by motion of the ground-contacting module in response to leaning of the support platform. A motorized drive coupled to the ground-contacting module causes locomotion of the vehicle and the subject therewith over the surface, while a control loop, in which the motorized drive is included, dynamically enhances stability in the fore-aft plane by operation of the motorized drive in connection with the ground-contacting module. In the event of failure of the control loop, the pivot connection of the support platform to the ground-contacting module may be locked, thereby ensuring stability of the static assembly.

Abstract: The invention provides a bow press, for use with a bow comprising a pair of resilient limbs extending outwardly in opposite directions from a central handle portion, the limbs each having an outer end. The bow press comprises first and second pulling members, a coupler, and first and second limb connectors.

Title: Wand assembly for a domestic appliance
Inventor: EVANS NICHOLAS ALEXANDER
IPC: F16L27/12

Granted: 2007-04-24
Abstract: A wand for a domestic appliance (e.g. vacuum cleaner) comprises a plurality of tubes (10, 20, 30, 40) which are dimensioned to telescope inside one another.  Each tube (10, 20, 30, 40) is associated with a securing mechanism (15, 25, 35) for securing the tube in an extended position with respect to another of the tubes. Adjacent securing mechanisms (15, 25, 35) are positioned on their respective tubes such that, when the tubes are retracted, one securing mechanism presses against another to release the other securing mechanism.  Thus, a user does not need to separately operate each securing mechanism (15, 25, 35) when extending the wand. Also, the tubes automatically secure themselves in an extended position with respect to one another. A hook (550) on the widest tube (10') cooperates with a collar (610) on the narrowest tube (40') to retain the tubes in a stored position.

Abstract: There is provided a switch unit with quite operation. A switch shaft connection shaft 24 is formed on a switch knob 22, and connected to a switch shaft 26. Therefore, the switch shaft 26 can move in response to an inclination restoration operation of the switch knob 22. Further, the switch shaft 26 has movement in the lateral direction regulated by a guide rail 17, which makes it possible to always exert pressing force vertically with respect to a tact switch 25. Moreover, a region where the tact switch 25 is pressed from the switch shaft 26 is constituted by a resilient member, which means that there is no striking noise when the switch shaft 26 strikes the tact switch 25, and it is possible to provide a switch unit that is quiet at the time of operation.

Abstract: A method and system for multi-level power management in an optical network is provided. They include three levels of power equalization. The first level of power management equalizes the powers of channels in a band of channels. The second level of power management equalizes the average powers of bands of channels on a fiber. The third level of control equalizes the powers of bands of channels on working and protection fibers for a path in the optical network. As a result, this multi-level power management in the network provides a dynamic, automatic method for the network to adjust to changing operating conditions and configurations and to maintain relatively stable network powers. Each level of power management may be implemented jointly or independently, and operates autonomously so that, for example, one modification comprises continuous first level control and only periodic second level control.
