Abstract: A button mechanism is provided, including a button element, a magnet connected to the button, a hollow tube, a first coil, and a second coil. The first and second coils are disposed on the tube. When the first coil generates a first magnetic field, the magnet is magnetically attracted by the first coil, and the button element is positioned in the first position. When the second coil generates a second magnetic field, the magnet is attracted by the second coil, and the button element is positioned in the second position.

Abstract: Some implementations described herein provide techniques and apparatuses for a stacked semiconductor die package. The stacked semiconductor die package may include an upper semiconductor die package above a lower semiconductor die package. The stacked semiconductor die package includes one or more rows of pad structures located within a footprint of a semiconductor die of the lower semiconductor die package. The one or more rows of pad structures may be used to mount the upper semiconductor die package above the lower semiconductor die package. Relative to another stacked semiconductor die package including a row of dummy connection structures adjacent to the semiconductor die that may be used to mount the upper semiconductor die package, a size of the stacked semiconductor die package may be reduced.

Abstract: A safety apparatus of a barbecue lighter includes a resistance unit, which is disposes in the trigger cavity of the casing, providing an additional resistance for press the ignition trigger; and a resilient element, which is coaxially attached to the resistance unit, urging and retaining the ignition trigger in an upper normal position. Therefore, the resistance means resists the depressing force applied on the ignition trigger by an under age child which the under age child has limited physical capability while an adult is capable of pressing the ignition trigger easily.
