    摘要: A direct current and a modulation signal are simultaneously applied to contact pads on a device under test, such as a laser diode, with a probe that reduces signal distortion and power dissipation by transmitting a modulated signal through an impedance matching resistor and transmitting of a direct current over a second signal path that avoids the impedance matching resistor.

    摘要: A toy vehicle launcher and supporting clamp are used in providing a gravity driven toy vehicle trackset. The clamp utilizes a ratcheting attachment member which facilitates the rapid sizing or adjustment for size for attachment to a table edge or the like. The launcher and clamp further provides a toy vehicle launcher having a trigger release for gravity driven launch of a toy vehicle down a coupled track segment. The angle of the toy vehicle launcher is adjustable to facilitate changes in launch angle and thereby changes in the amount of energy imparted to the toy vehicle.
