Abstract: Improved endpin block apparatus for stringed instruments are provided. The endpin block apparatus comprises an endpin support for securing and connecting an endpin to a stringed instrument. The endpin block apparatus may be fixedly attached to the instrument or may be able to rotate about an attachment location, allowing for adjustment of the angle of the instrument relative to the axis defined by the endpin and the musician. The endpin block apparatus provides one or more endpin insertion locations, allowing for one or more angles of the endpin relative to the axis of the instrument, which angle may be adjustable, and may allow for more of the instrument's weight to be borne by the endpin. The adjustable endpin angle and the adjustable endpin block apparatus rotation allow for a greater range of instrument location and angle, and more support of the instrument by the endpin, removing weight from the musician.

Abstract: The invention relates to an optical wavelength conversion device adapted to receive at least one first pump beam (?1) as an input and emitting a different wavelength output beam (?S), which includes: an optical cavity (CE); an optically non-linear medium (CNL) placed inside the optical cavity; and a control system (BA1) for controlling said optical cavity having the wavelength of the first pump beam; said control system being adapted to receive, as an input, a first signal (S1) representing the power stored in the cavity having said first wavelength and a second signal (S2) representing the power of the output beam. The invention also relates to a coherent light source comprising such a device and one or two pump laser sources (L1, L2).

Abstract: A method for controlling the operation of a generator connected to an electrical energy storage unit in a vehicle power train. An engine is connected to a drive shaft of the vehicle through a transmission and with an interrupting device with which the transmission of torque from the engine to the drive shaft is interruptible. When the transmission of torque between the engine and the drive shaft is interrupted the generator is driven from the drive shaft.

Abstract: A motor vehicle transmission having a continuously variable transmission ratio. The transmission includes an input-side torque converter that is optionally connectable on the output side through a first transmission stage with a predetermined gear ratio, or through a second, continuously variable transmission stage, to the output shaft of the transmission so that it transmits torque. The transmission ratio of the continuously variable transmission stage is adjustable in such a way that the rotational speed of the transmission output shaft remains constant when the transmission of torque is shifted from the first transmission stage to the second transmission stage.

Abstract: A power-branched, continuously variable vehicle transmission includes a CVT variable speed drive that is connected to an input shaft through a planetary gear train and to an output shaft through a multistage gearbox. In an alternative embodiment, one variable speed drive shaft of the variable speed drive is connected to an input shaft, and the variable speed drive shafts are connected to an output shaft through a planetary gear train module. The power-branched transmission is compactly constructed, but permits a high start-up torque and enables a wide transmission ratio spread.

Rotationally fixed connections corresponding to different gear ranges are producible between shafts of the transmission through gear pairings and or shaft connections provided with clutches.

Abstract: A continuously variable power-branched transmission for a motor vehicle, including an input shaft, a variable speed drive unit having pairs of conical disks and a continuously variable transmission ratio, a gear system, and an output shaft. Two control clutches connect the variable speed drive unit and the gear system so that when going through the entire transmission ratio range of the power-branched transmission the adjustment range of the variable speed drive unit is passed through a plurality of times. The transmission also includes rotational speed sensors and a controller that determines whether a change in rotational speed is triggered by a change in the transmission ratio, and when it is not triggered by a change in the transmission ratio, the controller adjusts the variable speed drive unit so that the change in rotational speed not triggered by a change in the transmission ratio is compensated.
