Abstract: A parking lock device for a transmission of a vehicle. The device comprising a wheel, a pawl for locking the wheel against rotation and an actuator unit arranged for movement of the pawl relative to the wheel. The pawl has a locked position where the pawl and the wheel are engaged and an unlocked position where the pawl and the wheel are disengaged. The pawl and the actuator unit are mechanically coupled to each other by a pin and slot mechanism having a guide slot and a guide pin received by the guide slot.

Abstract: A digital-to-analog circuit arrangement that can be used, for example, in radio transmitters, includes a Digital-to-Analog Converter (DAC) whose output is connected directly to a mixer. A periodic signal is also provided to the mixer. The frequency of the periodic signal provided to the mixer, is an integer multiple of half the update rate frequency of the DAC. In an embodiment of the invention, the frequency of the periodic signal provided to the mixer, is half the update rate frequency of the DAC. An intermediate frequency (IF) filter can be provided. downstream of the mixer.

Abstract: A phase locked loop frequency synthesizer in which the output frequency is changed in a series of steps in order to reach a final frequency value. The steps are computed and stored in a memory in a control unit. The steps are chosen to approximately cancel the poles of the transfer function of the synthesizer. The phase locked loop provides increased switching speed.
