Abstract:
A hybrid vehicle includes a multi-mode power system. The power system includes a battery, an electrical power input, a first motor/generator, a second motor/generator, and a clutch. A first operating mode is defined by deactivation of the internal combustion engine and the operation of the vehicle by electrical force provided from the battery to the second motor/generator. In a second operating mode, activation of the internal combustion engine generates electrical power by providing rotational force to the first motor/generator. In a third operating mode, engagement of the clutch couples the internal combustion engine and the second motor/generator to provide rotational force to the wheels. In a fourth operating mode, engagement of the clutch couples the internal combustion engine with the second motor/generator, and the first motor/generator further provides rotational force to the wheels.
Abstract:
A data exchanging method is provided. A data transmitting device determines a first start position and a first end position of a first touch track according to sensing signals from a first touch display of the data transmitting device. If one icon is displayed on the first start position, and the first end position is on the edge of a first user interface, the data transmitting device transmits data corresponding to the icon to a server. A data receiving device determines a second start position of a second touch track according to sensing signals from a second touch display of the data receiving device. If the second start position is on the edge of a second user interface, the data receiving device transmits a download command to the server to request the server to transmit the data received from the data transmitting device to the data receiving device.

Abstract:
An electronic device is provided. The electronic device includes a display, a sliding member, and a main body. The display includes two connecting members. The sliding member is rotatably connected to the connecting member. The main body includes a housing, a first casing, and a second casing. The housing defines two slots. Each slot extends through the housing. The first casing is secured to the housing. The first casing and the housing cooperatively define a first receiving space communicating with the slots. The sliding member is slidably received in the first receiving space. The second casing is secured to the housing. The second casing and the housing cooperatively define a second receiving space to receive the display. The second receiving space communicates with the first receiving space and defines an opening. The display is pushed into and out of the second receiving space from the opening.
Abstract:
This invention provides methods for electric vehicle motor control and rotor position detection and fault-tolerant processing. The rotor position signal sampled by the system is compared with the previous rotor position θ0. When there is a sudden change, the current position signal acquired is discarded. Instead, a fault-tolerant processing strategy for use during an error condition is employed where the previous sampled rotor position θ0 is used as a base to determine the corrected current rotor position angle Θ1′. Then the correcting value is used to control the electric motor. Thus, during the motor operation, when the detection of the motor rotor position is erroneous because of a sensor such as a revolver that may be interfered by external conditions such as electromagnetic fields or vibrations or when there is a breakdown in other related hardware components or transmitting circuits, the fault-tolerant processing methods of this invention can effectively prevent the motor from losing control and allow it to maintain its continuity and stability.
Abstract:
An electronic device with a holding mechanism is provided. The device includes a main body, a housing, a carriage, a first elastic member, a stopper member, a second elastic member, and a button. The housing includes a first sidewall, a second sidewall opposite to the first sidewall, and a third sidewall formed between the first sidewall and the second sidewall, an opening is defined in the second sidewall.
