Abstract: A padlock having a removable or interchangeable shackle is disclosed. The padlock comprises a lock body and a shackle, the shackle being movable in an axial direction between a locked position and an unlocked position, the short leg being withdrawn from the lock body in the unlocked position. The padlock also comprises a retaining shaft receivable within a corresponding bore of the lock body, wherein the long leg includes a longitudinal recess for providing a travel path for the movement of the shackle from a locked position defined by the retaining shaft engaging a first end of the longitudinal recess to an unlocked position defined by the retaining shaft engaging a second end of the longitudinal recess to prevent the shackle from being removed from the lock body when the shackle is in the unlocked position.

Abstract: A method for determining a touch position and a touch control chip are disclosed. The method includes: determining (S310) a variation caused by a noise to raw data of a capacitive touch screen; determining (S320) a noise processing method of a raw value of the capacitive touch screen according to the variation caused by the noise to the raw data of the capacitive touch screen; performing (S330) noise cancellation processing on a first raw value set of the capacitive touch screen using the noise processing method, to obtain a first processed value set; and determining (S340) a touch position on the capacitive touch screen according to the first processed value set. The method for determining a touch position and the touch control chip contribute to improving accuracy of the touch position.

Abstract: A method and apparatus for updating a current reference value of a touch screen, a touch screen and an electronic terminal thereof are provided. The method includes: obtaining a current original value of a sampling node on the touch screen; determining a fitting original value of the sampling node according to a fitting relationship between a backup reference value and the current original value; calculating a fitting residual value between the fitting original value and the current original value; and judging whether a trigger condition for reference value update is satisfied according to the fitting residual value, and updating the current reference value if the trigger condition for reference value update is satisfied.

Abstract: A multiplexed capillary electrophoresis (CE) method using fluorescence detection for a plurality of samples is improved economically and in terms of instrument complexity by irradiating the plurality of samples with a single non-coherent light source as the excitation light source for all of the channels. The preferred light source is a light-emitting-diode (LED).
