Abstract: A resonant flyback power converter includes: a first and a second transistors which form a half-bridge circuit for switching a transformer and a resonant capacitor to generate an output voltage; a current-sense device for sensing a switching current of the half-bridge circuit to generate a current-sense signal; and a switching control circuit generating a first and a second driving signals for controlling the first and the second transistors. The turn-on of the first driving signal controls the half-bridge circuit to generate a positive current to magnetize the transformer and charge the resonant capacitor. The turn-on of the second driving signal controls the half-bridge circuit to generate a negative current to discharge the resonant capacitor. The switching control circuit turns off the first transistor when the positive current exceeds a positive-over-current threshold, and/or, turns off the second transistor when the negative current exceeds a negative-over-current threshold.

Abstract: A transparent display panel with driving electrode regions, circuit wiring regions, and optically transparent regions is provided. The driving electrode regions are arranged into an array in a first direction and a second direction. An average light transmittance of the circuit wiring regions is less than ten percent, and an average light transmittance of the optically transparent regions is greater than that of the driving electrode regions and the circuit wiring regions. The first direction intersects the second direction. The circuit wiring regions connect the driving electrode regions at intervals, such that each optically transparent region spans among part of the driving electrode regions. The transparent display panel includes first signal lines and second signal lines extending along the circuit wiring regions, and each circuit wiring region is provided with at least one of the first signal lines and at least one of the second signal lines.

Abstract: A lock assembly has a lock and a dust cover. The dust cover has a cover body, a connecting portion and a mounting ring. An annular insertion wall protrudes from a surface of the cover plate. Two opposite ends of the connecting portion are connected to the cover body and the mounting ring respectively. The lock has a lock cylinder. A keyhole is formed in one end of the lock cylinder. The lock cylinder has a door abutting portion and an annular mounting groove. The door abutting portion abuts against a door when the lock is mounted on the door. The mounting ring of the dust cover is rotatably mounted around the annular mounting groove. The annular insertion wall can be mounted in and engages with the keyhole. The rotatable dust cover makes the installation, use, and maintenance of the dust cover more convenient.

Abstract: A pickproof lock has a hollow housing, a lock shaft and a sleeve mounted in the housing, multiple axial pin sets mounted in the lock shaft and the sleeve, and at least one radial pin set mounted in the housing and the lock shaft. When unlocking the pickproof lock, the key is able to push the axial pin sets and the at least one radial pin set to unlocking positions, so as to drive the lock shaft to rotate and to unlock the pickproof lock. The complexity of the pickproof lock is increased. People with bad intentions are unable to unlock the pickproof lock with a lock picking tool, such as a round tube. Accordingly, personal goods or private matters can be safely protected by the pickproof lock.

Abstract: A diagnostic method for inflammatory diseases, and the diagnostic kit used in the method. The diagnostic method includes the use of a novel tryptophan metabolite, 5-methoxytryptophan (5-MTP), as a diagnostic biomarker of inflammation. Specifically, a highly specific competitive ELISA is provided to measure 5-MTP level in human serum for gauging occurrence and severity of inflammatory diseases, including sepsis and systemic lupus.

Abstract: A sliding padlock has a shell, a locking assembly, a shackle and a resilient element. The locking assembly is mounted in the shell and has a lock cylinder and a lock rod. The shackle is mounted in a locking end of the shell, is selectively blocked by the lock rod and abuts the resilient element. Because of the resilient element, the shackle is held to abut the shell without external force even when the lock cylinder is unlocked. Therefore, the sliding padlock still holds an object in position when unlocked so a user may take the object easily without using a key.

Abstract: A lock assembly with a picking resistant shield has a main lock and a key. The main lock has a shield attached to a front end of the main lock. The shield has an inner recess and an outer recess smaller than the inner recess. The key has a neck corresponding to the outer recess of the shield and a driving tube corresponding to the inner recess of the shield and is selectively mounted into the shield to unlock the main lock. Thus, the shield prevents the main lock from being picked from the front end of the main lock by a picking tool. Personal goods or private matters being protected by the lock assembly with the picking resistant shield are safe.

Abstract: A padlock has a shell, a lock cylinder, a shackle and a resilient element. The lock cylinder is mounted in the shell and has a lock rod. The shackle is mounted slidably through a front opening of the shell and has a distal end, a proximal end and a protruding segment. The distal end is selectively received in a mounting slot of the shell. The protruding segment selectively abuts the lock rod to keep the shackle from sliding. The resilient element is mounted in the shell and presses against the proximal end of the shackle. With the resilient element, the distal end of the shackle is maintained in the mounting slot without any external force. Therefore, the padlock may still hold an object in position without locking and then the user may take the object easily without using a key.

Abstract: The cylinder lock has a housing, a fixed hollow cylinder, a rotatable hollow cylinder and a locking bar. The locking bar has a mounting portion with planes, shoulders and a resilient element mounted around the mounting portion. The rotatable hollow cylinder has a non-circular mounting hole corresponding to and held slidably the mounting portion of the locking bar to enable synchronous rotation and relative sliding movement of the rotatable hollow cylinder and the locking bar to make the cylinder lock active. By the modification of the locking bar and the rotatable hollow cylinder, the structure of the cylinder lock is effectively simplified and the fabrication of the cylinder lock is easy.
