Abstract: A rotor blade for fastening on the rotor of a turbomachine, especially of a compressor of a gas turbine, comprises a blade airfoil and a blade root (15) which adjoins the lower end of the blade airfoil and extends along a blade axis and by which the rotor blade, in an encompassing slot which is arranged on the outer periphery of the rotor, is retained between two spacers (12, 18) which follow each other in the circumferential direction and which in their turn are retained in the slot, wherein the blade root (15) is formed with a T-shape in cross section and by shoulders (16, 16') which extend in the circumferential direction fits under the adjacent spacers (12, 18), and the spacers (12, 18), in the direction of the blade axis, engage by retaining surfaces (20) in undercuts (24) in the slot.     A reduced production cost with comparable service life is achieved by the T-shaped blade root (15) being milled, and, for reducing the mechanical stresses at the transitions of the blade root (15) to the shoulders (16, 16'), by a relief groove (21), which extends in the direction of the blade axis, being provided in each case.

Patent CA-2645628-A1 (CA)
Inventor: DIETHORN ERIC JOHN
IPC: H04M3/527
Filed: 2008-12-01
Abstract: A technique is disclosed that optimizes the background noise experienced by a party who is calling into a call center. Working as part of an overall call-assignment algorithm, the technique considers the acoustic noise that is present in the vicinities of multiple call-center agents who are otherwise satisfactory candidates to handle a call.  The technique then selects an agent to handle the call who is associated with an optimal acoustic noise.  Typically, the selected agent is associated with lowest background noise level. The background noise is monitored at each call agent's station by evaluating the signals that are present at the agent's microphone. Usually, this is done when a call agent is between calls and, as a result, is not using her headset at that moment. In other words, the background noise is actually measured, and the measurements are then used to assign a call agent to the incoming call.

Inventor: DAI XIAOLI
IPC: G02B5/18
Filed: 2009-06-18
Abstract: A method of producing a thermally stable grating allows the grating to be placed in environments where temperatures reach 1000 °C and where the grating is relatively stable and has very low loss from scatter. These gratings have spectral characteristics that allow them to be concatenated so as to form a sensor array. The method requires a step of lowering the characteristic intensity threshold of a waveguide by at least 25%, followed by irradiating the waveguide with femtosecond pulses of light having a sufficient intensity and for a sufficient duration to write the grating so that at least 60% of the grating remains after exposures of at least hours at a temperature of at least 1000 °C. Pre-writing a Type I grating before writing a minimal damage Type II grating lowers the characteristic threshold of the waveguide so that a stable low damage type II grating can be written; alternatively providing a hydrogen or deuterium loaded waveguide before writing the grating lowers the characteristic threshold of the waveguide.

Title: Nomogram computation and application system and method for refractive laser surgery
Inventor: PETTIT GEORGE H
IPC: A61B3/103
Filed: 2008-06-02
Abstract: A method for optimizing a prescription for laser-ablation corneal treatment includes receiving a measured correction prescription for a current patient. Next a database of treatment outcomes on a plurality of previously treated patients is accessed. The database contains a desired correction, and an actual correction. A difference between the desired correction and the actual correction represents an over- or undercorrection resulting from surgery. From the difference data is calculated a distribution of data points as a function of correction level. From the data-point distribution is calculated a statistically based offset applicable to the correction prescription for matching actual corrections with desired corrections. From the data-point distribution is calculated a confidence interval of the data using a predetermined confidence level. The statistically based offset is then adjusted based upon the confidence interval to provide an optimized prescription. The adjusted offset is then output for use in performing a refractive procedure.
