Method and apparatus for controlling alarm clock
Embodiments of the present disclosure disclose methods and apparatuses for controlling an alarm clock. Processing circuitry of an apparatus determines an alarm time for the alarm clock of a first terminal device. When a time difference between a present time of the first terminal device and the alarm time is determined to reach a preset duration, the processing circuitry determines whether a second terminal device is located within a reachable distance from the first terminal device. The second terminal device is associated with a first wearable device used by a user. When the second terminal device is determined to be located within the reachable distance from the first terminal device, the processing circuitry acquires, from the first wearable device, a sleep signal indicating a sleeping status of the user, and controls the alarm clock and a second wearable device associated with the first terminal device based on the sleep signal. |

Hybrid vehicle control device
For a hybrid vehicle including an engine, a motor generator, and a belt-type continuously variable transmission, a controller performs a low speed position return expediting control in response to a downshift request accompanying deceleration. During the low speed position return expediting control, the controller increases a differential pressure between a primary pressure and a secondary pressure and cause a downshift toward a lowest speed position transmission ratio by reducing the primary pressure, and further reduces the primary pressure when the secondary pressure becomes greater than or equal to a trigger threshold value during the downshift; and terminates the low speed position return expediting control when an actual secondary pressure decreases to a secondary pressure minimum level. The controller further sets a secondary pressure lower limit higher than the secondary pressure minimum level during the low speed position return expediting control. |

Continuous variable speed transmission using variable coupling arrangement
The variable speed transmission uses multiple fluid couplings to provide a sturdy, durable variable output ratio transmission by using hydraulic fluid to vary the output. Each fluid coupling has an independent output shaft driven by the respective fluid coupling turbine. Output shafts drive alternate gears (i.e., first and third at a first fluid coupling and second and fourth at a second fluid coupling). This configuration alternates gear shifts between the fluid couplings allowing the next gear up or down to be engaged before disengaging the current gear, for uninterrupted gear changes in both up and down shifting. A fifth gear would be driven by a gear connected to the fluid coupling input shafts. Gears could be engaged with hydraulic clutches or syncromesh gears. This combined with variable slip fluid couplings allows for better torque and control. |
