摘要： An electromechanical system comprising: a rotor comprising a plurality of teeth spaced about a circumference of the rotor, wherein the teeth of the rotor are equally spaced about the rotor according to a tooth spacing angle, and are skewed in an axial direction such that the circumferential positions of the teeth of the rotor vary along the axial length of the rotor, and first and second stator segments, each extending partway about the rotor and comprising a field winding and poles arranged to magnetically interact with the teeth of the rotor such that an alternating current (AC) back-emf is induced in the field winding upon rotation of the rotor. The poles of the first stator segment are angularly displaced about the rotor from the poles of the second stator segment such that the back-emf induced in the field winding of the first stator segment is phase shifted with respect to the back-emf induced in the field winding of the second stator segment.

摘要： Disclosed are a method of controlling a mode transition in order to predict a driver's required torque to reduce non-driving fuel loss, and a hybrid vehicle for performing the method in particular, the method of controlling a mode transition of a hybrid vehicle may include: determining whether to change a first mode to a second mode based on a first torque; determining a second torque expected to be generated at a near-future time after a current time; determining whether or not an engine clutch engagement is possible at the near-future time based on the second torque or a predicted acceleration; and performing the change from the first mode to the second mode when the mode change from the first mode to the second mode is determined and the engine clutch engagement is possible.

摘要： An automobile power system in a vehicle may include an intake pipe supplying external air to an engine supplying power to driving wheels, a canister connected with a fuel tank to absorb evaporation gas produced in the fuel tank, an active purging system compressing and supplying the evaporation gas absorbed in the canister to the intake pipe, a diverging line extending from the active purging system to the engine, a diverging valve mounted on the diverging line, and a starting motor rotating a crankshaft when the engine is started. In addition, the evaporation gas absorbed in the canister is supplied to the engine through the diverging line before the engine is restarted, and then the starting motor is operated.

摘要： A storage system and method for caching a single mapping entry for a random read command are provided. In one embodiment, a storage system is provided comprising a memory and a controller. The controller is configured to determine whether a read command received from a host is a random read command, wherein the read command comprises a logical address; and in response to determining that the read command received from the host is a random read command, caching only an associated logical-to-physical address map entry from a logical-to-physical address map stored in the memory instead of caching a larger segment of the logical-to-physical address map that contains the entry and other entries. Other embodiments are provided.

摘要： A gear shifting apparatus for a multi-speed transmission for an electric vehicle includes a shifting unit controlling gear shifting by a torque of an actuator, and a parking unit controlling a parking state by the torque of the actuator. In particular, the actuator includes a control motor transmitting a driving torque to a first driven gear and a second driven gear through a drive gear externally gear-meshed with the driven gears, and the shifting unit includes: a shift fork slidably mounted on a fork rail and activating the gear shifting; a profile drum connected to the first driven gear externally engaged with the drive gear, and having a profile groove formed along an exterior circumference of the profile drum; and a shift lug integrally formed with the shift fork and coupled with the profile groove.

摘要： A system includes an audio transducer. The audio output of the transducer may be directed at an operator. The directionality of the audio output may ensure privacy in audio delivery. Further, the directionality of the audio output may reduce the potential for other nearby individuals to be disturbed by the audio output. A directed audio system may control the content of the audio output. The content of the audio output may be configured for applications in individual operator workspaces, multiple-operator common spaces, shared-use spaces or a combination thereof. The directed audio system may customize the audio output in accord with a stored audio profile for the operator.

摘要： An apparatus for controlling a lane change of a vehicle may include: a processor determining whether a condition of interrupting a lane change procedure occurs, during controlling the lane change. In particular, when the condition of interrupting the lane change procedure is satisfied, the processor determines whether to interrupt the lane change procedure or whether to return the vehicle to an original lane to control the vehicle depending on a result of the determinations. The apparatus further includes a storage to store the result determined by the processor.
