Abstract: Embodiments of the apparatus of this disclosure can comprise a portable compactor apparatus for compacting material in a container, wherein the portable compactor apparatus comprises a. At least one base support, b. A linear actuator attached to the at least one base support, the linear actuator having an extendable and retractable shaft, the shaft having a proximal end within the actuator and a distal end, c. A compression head connected to the distal end of the shaft, and d. Control means for controlling extension and retraction of the shaft, The container having a top lip portion, the base support positioned on the top lip portion, the linear activator having a first position and a second position, in the first position the shaft is fully retracted into the linear actuator, in the second position the shaft is extended further below the top lip portion of the container.

Abstract: A high bandwidth signal probe device and a method of probing a high bandwidth signal are provided. The high bandwidth signal probe device includes a probe tip for probing a stub of a backdrilled via of a printed circuit board. The probe tip is adapted to fit in the backdrilled via. The probe tip has a length adapted to reach the stub of the backdrilled via. The probe tip is adapted to contact a plated portion of the stub of the backdrilled via. A resistive element is associated with the probe tip. The method includes inserting a probe tip of a signal probe device in the backdrilled via, placing the probe tip in contact with a plated portion of the stub of the backdrilled via, and receiving an electrical signal through a path which includes a resistive element of the probe tip of the signal probe device.
