摘要： A method of controlling a motor is provided. The method may determine a speed of the motor, and engage a soft chopping routine on a first switch and a second switch of each phase if the motor speed is relatively low. The first switch may be driven by a first pulse width modulated PWM signal and the second switch being driven by a second PWM signal. The first and second PWM signals may be alternatingly configured such that at least one of the first switch and the second switch is closed at any point during the distributed soft chopping routine and both the first switch and the second switch are never simultaneously open.

摘要： A method of voltage supply management for an electric drive system includes receiving a voltage signal (1002) indicative of a voltage in a supply link, and one or more condition signals that are indicative of an operating condition of the electric drive system. A difference between a desired voltage value (1008), which is calculated based on the voltage signal (1002) and the one or more condition signals, and the voltage signal (1002) yields a voltage error signal (1014). The voltage error signal (1014) is evaluated to indicate an over-voltage condition or an under-voltage condition. Power is dissipated from the supply link when an over-voltage condition is present and a torque command limit with respect to the one or more electric drive motors (210) is imposed when an under-voltage condition is present.

摘要： A self-adjusting cup holder is provided. The cup holder includes a receiving area, compensating levers, and biasing members for biasing the compensating levers to a first position. The receiving area is configured to receive a portion of a drinking vessel. The compensating levers are disposed in slots defined in the wall of the receiving area. A first end of the compensating levers is pivotally connected to a portion of the wall such that a first edge of the levers is movable between the first position and a second position. The first edge is within the receiving area when the levers are in the first position. The first edge is farther from the sidewall in the first position than in the second position.

摘要： Particular embodiments detect events associated with information about activities that a user has engaged in. The activities may be associated with a location or location-agnostic. Based on the received information, the social-networking system sends the user a request for follow-up information after an appropriate time delay. The time delay may vary based on the user activity and the context of the event that triggered the request. After the follow-up information is received, such information is stored in the social-networking system and may be used to determine recommendations, sponsored stories, advertisements, etc. to send to friends of the user. The information may also be used for ranking or filtering recommendations.
