Abstract:
A throttle control system includes a pressure comparison module and a throttle plate control module. The pressure comparison module determines an inlet pressure upstream from a throttle body and an outlet pressure downstream from the throttle body. The throttle plate control module controls a position of a throttle plate based on the inlet pressure and the outlet pressure.
Abstract:
A method includes determining an amount of power currently available from a battery for tractive torque as an amount of power stored in the battery less an amount of power required to power other vehicle components, and less an amount of power required to start the engine. An output torque limit when torque is provided only by the motor and power required to provide the output torque limit are determined based on test data. A maximum output torque is calculated by multiplying the amount of power determined to be currently available for tractive torque by a ratio of the output torque limit to the amount of power required to provide the output torque limit. The current output torque may be reduced at a predetermined rate until within a predetermined range of the lesser of the maximum output torque and the output torque limit if an engine start is requested.
Abstract:
Disclosed herein is a method of welding superalloy articles. A buttered layer is attached to a first article formed from a superalloy. A buttered layer is attached to a second article formed from a superalloy. Residual stresses are relieved between the buttered layer and the superalloy. Matching faying surfaces are established at the buttered layers of the articles. And, the faying surfaces of the articles are welded together to form a welded assembly, wherein after welding, a heat affected zone is within the buttered layers.

Abstract:
A method for managing a threshold increase in output torque capability in a vehicle includes detecting the threshold increase in output torque capability using a controller, and automatically limiting, via the controller, a rate of change of an actual output torque from a transmission of the vehicle in response to the threshold increase. The actual output torque is provided via a traction motor solely using battery power from an energy storage system. The method may include calculating a difference between the threshold increase and the actual output torque, and limiting the rate of change using a rate that is proportional to the difference. A vehicle includes the ESS, a transmission, and a controller. An output member of the transmission is powered using electrical energy from the ESS. The controller manages an increase in output torque capability as noted above.
Abstract:
A system in a turbine engine for preventing wear on a tip shroud of a turbine blade that includes a pocket formed in a contact surface of the tip shroud and a plug that fits within the pocket and has a durable outer surface. The durable outer surface may include a cobalt-based hardfacing powder. The pocket may be machined out of the contact surface, and the plug may include a plug of predetermined size that fits snugly into the pocket. In some embodiments, the durable outer surface may substantially align with the contact surface after the plug is fitted into the pocket. In other embodiments, the durable outer surface may remain slightly raised from the contact surface after the plug has been fitted into the pocket.
Abstract:
Typically, a laser emits significant energy after a control signal is generated to disable the power supply. The inherent delay between generation of a control signal for shutting off a laser power supply and actual termination of an output beam pulse in response to the control signal, is compensated in the context that the control signal is generated automatically upon coincidence of measured output beam power with a preset threshold value. Power supplied to a laser is modulated to cause generation of a pulsed laser output beam. The cumulative energy of each output beam pulse is monitored and a feedback signal indicative of measured output beam pulse energy is supplied to the power supply. The feedback signal is compared with a user-selected threshold value, and a control signal is generated for terminating the output beam pulse (by terminating input power to the laser) when the measured output pulse energy reaches the threshold value. By generating the threshold signal to have a value representing a threshold output beam pulse energy that is lower than a desired output beam pulse energy, the threshold signal is generated in a manner which compensates for the inherent delay between generation of the control signal and the actual termination of the output beam pulse in response to the control signal. This prevents delivery of significant output beam energy in excess of a user-selected amount.
Abstract:
An adjustable seating assembly is disclosed having a base with a first end, a second end opposite the first end, and a length extending from the first end to the second end. A frame assembly has a pair of support legs coupled to the base along the length. A seating-support surface is disposed above the base and coupled to the frame assembly. A chest-support surface is disposed above the base and coupled to the frame assembly and the chest-support surface is orientated at an acute angle with respect to the seating-support surface. The pair of the support legs are selectively translatable along the length of the base in a first direction and a second direction opposite the first direction so as to selectively rotate the chest-support surface and the seating-support surface simultaneously while maintaining the acute angle between the chest-support surface and the seating-support surface during the rotation.
