摘要:
The present invention involves a cross-linked carboxylic acid hydrophobically modified copolymer product in which cross-linked carboxylic acid is modified with a non-hydrocarbyl hydrophobe, namely, poly(dimethyl siloxane) or fluoronated alkyl methacrylates.

A new method is disclosed for providing wireless fixed access from an array of service antennas to a population of local terminals. In implementations, a service transceiver station (STS) performs beamform precoding using channel state information (CSI) obtained from transmissions by the local terminals, and the STS performs power allocation using slow fading coefficients which are static over the service antenna positions and over a frequency range spanning at least some carriers used for downlink transmission.
摘要:
A load bearing member includes at least one elongated tension member having at least one wire and a protective coating on the elongated tension member. The protective coating includes a first corrosion inhibitor having an oxide-forming metal, a second corrosion inhibitor having a rare earth metal, and a third corrosion inhibitor having an organic material.

An adjustable hinge connects a base section and a top section of a laptop computer. The base section can include a keyboard. The top section can include a display screen. When the laptop computer is in a closed position, the adjustable hinge can collapse into the base section and the top section. When the laptop computer is in an open position, a portion of the adjustable hinge can be extended from the base section to adjust a distance between the display screen and a user. Another portion of the adjustable hinge can be extended from the top section to adjust a height of the display screen.

摘要:
A vehicle includes an engine that generates an engine torque and a motor that generates a motor torque. A transmission can receive the engine torque, the motor torque, or both. The transmission includes a first gear set and a second gear set, as well as a first clutch that at least partially engages to transfer torque to the gears in the first gear set and a second clutch that at least partially engages to transfer torque to the gears in the second gear set. A controller can control the engine torque and the motor torque to control a speed of the engine to follow a desired speed profile. The controller can also control the engagement of the first clutch and the second clutch to optimize a desired gear state to minimize system losses.
摘要:
A hybrid powertrain includes an engine having a crankshaft, and a hybrid transmission having an input member, an output member, and at least one motor/generator operable to provide or receive torque. A damper connects the crankshaft with the input member. A bi-directional rotational position sensing system operatively connects with either the crankshaft or an input side of the damper, and is configured to sense the rotational position and direction of the crankshaft, and provide a position signal indicative thereof. At least one controller is configured to receive the position signal and to provide a torque command to the motor/generator based at least in part on the position signal. The torque command is operable to cause the motor/generator to substantially cancel an expected engine torque pulse associated with the sensed rotational position during starting of the engine with the damper open. A method for controlling the hybrid powertrain is provided.
摘要:
A control strategy for launching a motor vehicle includes using an electric motor to provide high torque at low speeds during synchronization of launch clutches. An internal combustion engine is started and connected with the electric motor to provide additional torque capacity. Selective engagement and disengagement of an engine disconnect clutch prevents the engine start from interfering with the motor vehicle launch.
摘要:
A hybrid transmission has an input member, an output member, three planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The torque transmitting devices include clutches and brakes. The input member is driven by an internal combustion engine and an electric motor.
