Abstract: A clock generator device includes a detector circuit, a calibration circuit, and a free running oscillator. The detector circuit is configured to determine whether a reference clock signal is received from a transmission interface to output an enable signal. The calibration circuit is configured to generate a first signal in response to the enable signal and an output clock signal, and compare the first signal with a predetermined value to generate a calibration signal. The free running oscillator is configured to adjust a frequency of the output clock signal in response to the calibration signal.

Abstract: A test pen includes an integral hollow pen barrel. The hollow pen barrel is divided into four sections in order being a dip section, a testing and observation section, a drying section, and a sealed rear section. The dip section has a front opening allowing a slender water-absorbing member to pass therethrough. An air balance hole is provided on the dip section of the pen barrel to facilitate liquid siphoning. A pen cap for capping the dip section has a flexible inner fringe for keeping the dip section airtight. A rear plug is provided for sealing the rear section. A testing member is installed in the testing and observation section. The testing member includes a support card, a solid carrier, a conjugate release pad partially overlapping the front end of the solid carrier, an absorbing pad partially overlapping the rear end of the solid carrier, and a cover tape.

Abstract: A nipple includes a nipple body, a peripheral flange, an air intake tube, and an inlet hole. The flange extends outwardly from a periphery of the nipple body, and has upper and lower flange surfaces. The lower flange surface has a recess which is confined by a side wall and a top wall. The air intake tube projects into the recess from the top wall, and has an end part formed with a split for passage of air. The split divides the end part into two openable valve members. Reinforcement ribs respectively connect the valve members to the side wall, thus strengthening the valve members.
