Abstract: A pliers includes a first body with an engaging groove and a second body with an elongated slot pivotally connected with each other. The elongated slot includes a left and right positioning grooves and a protruding portion disposed therebetween. A tap button is pivotally connected to the second body. A supporting member is disposed between the second body and the tap button. When the first body comes close to the second body, the tap button can be tapped to a first position and engaged in the engaging groove. Thus, the first body is blocked and cannot pivot relative to the second body. The tap button can be tapped to a second position and detached from the engaging groove. Thus, the first body is pivotable relative to the second body. A positioning block is extending from the tap button and can be engaged in any of the positioning grooves for positioning the tap button.

Abstract: Snap ring pliers include two levers, two posts, and two protruding blocks. The two levers are pivotally connected to each other and relatively pivotable. The two levers each have a control end at a distal end thereof. The two posts are fixed to the control ends of the two levers, respectively. The posts each have a complete surface without a notch. The posts each have a non-circular cross-section and at least one an arris for leaning against a perforation of a snap ring. The two protruding blocks are respectively fixed to distal ends of the two posts for restraining the snap ring from being separated from the posts, thereby controlling the snap ring stably.

Abstract: A successive approximation register (SAR) analog-to-digital converter (ADC) is disclosed. A first and second capacitor DACs receive a first and second input signals respectively. A first coarse comparator compares an output of the first capacitor DAC with a window reference voltage, a second coarse comparator compares an output of the second capacitor DAC with the window reference voltage, and a fine comparator compares the output of the first capacitor DAC with the output of the second capacitor DAC. A SAR controller receives outputs of the first and second coarse comparators to determine whether the outputs of the first and second capacitor DACs are within a predictive window determined by the window reference voltage. The SAR controller bypasses at least one phase of analog-to-digital conversion of the SAR ADC when the outputs of the first capacitor DAC and the second capacitor DAC are determined to be within the predictive window. The SAR controller decodes the outputs of the first and second coarse comparators and the fine comparator to obtain a converted output of the SAR ADC.

Abstract: The present invention is directed to a multiplying digital-to-analog converter (MDAC) and its method. First ends of capacitors are electrically coupled to an inverting input node of an amplifier, wherein two of the capacitors are alternatively configured as a feedback capacitor. Each capacitor is composed of at least two sub-capacitors. Second ends of capacitors are electrically coupled to an input signal via a number of sampling switches, and the second ends of the capacitors are electrically coupled to DAC voltages respectively via a number of amplifying switches. A sorting circuit is configured to sort the sub-capacitors, wherein the sorted sub-capacitors are then paired in a manner such that variance of mismatch among the sub-capacitors is thus averaged.

Abstract: Briefly, in accordance with one or more embodiments, a pathloss gap between a downlink pathloss from a base station to a mobile station and an uplink pathloss from the mobile station to the base station is estimated. An initial offset value for uplink power control of the estimated pathloss gap is calculated based at least in part on said estimating. An offset value for an uplink data channel or an uplink control channel, or combinations thereof, is set based at least in part on the initial offset value. The pathloss gap for uplink power control is compensated using the set offset value.
