A hydraulic port protection plug for insertion into a hydraulic port in a shock absorber assembly, where the hydraulic port protection plug comprises a cap portion with a disc-shaped end wall and a tubular body that extends from the cap portion to define an open-ended cavity. The open-ended cavity extends within the tubular body of the hydraulic port protection plug and is bounded at one end by the cap portion. A self-closing pressure relief opening extends through the cap portion and is arranged in fluid communication with the open-ended cavity. At least a portion of the cap portion is made of an elastic material that permits the self-closing pressure relief opening to open and close in response to pressure changes.

A power amplifier with adjustable voltage standing wave ratio is described which comprises an amplifier unit, a coupler configured to obtain an incident power and a coupled reflected power, and a power control unit. The power control unit is configured to control the amplifier unit. The power control unit has two power detectors configured to provide actuating variables which correspond to the incident power and the reflected power, respectively. The power control unit comprises two digital potentiometers which are configured to variably weight the actuating variables wherein the power control unit is configured to determine a control variable for the amplifier unit based on the actuating variables such that a predetermined power level related to a set value of the voltage standing wave ratio is not exceeded by the incident power and/or the reflected power. Further, a radio frequency electronic device and a method are described.

There is provided a hole plug. The hole plug has a main body portion and a seal flange portion. The main body portion has a closing portion, an inner wall portion, an outer wall portion. The seal flange portion extends outwards from the outer wall portion and has an abutment portion. A first recess portion is provided on an outer surface of the seal flange portion, a thin portion whose minimum thickness is thinner than a thickness of a portion of the outer wall portion which is located closer to the other end side thereof than the engaging portion is formed on the first recess portion. The thin portion is disposed closer to a radially inner side of the seal flange portion than a position on the abutment portion which is located nearest to the outer wall portion.
