Abstract: A source driver with reduced number of latch devices includes a master latch device and at least one slave latch device. The master latch device has a first transmission gate, a first inverter, a second inverter, a first enable gate, and a second enable gate. The output of the second inverter is connected to the input of the first inverter. The at least one slave latch device has a second transmission gate, a third inverter, and a fourth inverter. When the first enable gate and the second enable gate receive a latch enable signal and a complementary latch enable signal respectively, the master latch device and the at least one slave latch device are concurrently driven to latch data.

Abstract: A tool box is equipped with a dual-colored handle. The dual-colored handle includes a frame of a color and a pad of another color. The frame is formed with two axles. The pad is formed with two rings each. Each of the rings is placed around and on a corresponding one of the axles as the frame and the pad are joined together.

Abstract: The present invention provides a level shifter. In an embodiment, the level shifter includes first to sixth transistors. The first and second transistors have common control nodes coupled to a first bias voltage, receive a pair of input signals and respectively provide a first output node and a second output node. The fifth and sixth transistors have common control nodes coupled to a second bias voltage to form a current mirror. The third transistor is coupled between the first and the fifth transistors and has a control node coupled to the second output node. The fourth transistor is couple between the second and the sixth transistors and has a control node coupled to the first output node.

Abstract: A hand tool-holding apparatus includes a frame and a storage element located in the frame. The storage element includes at least one chamber defined therein, at least one aperture in communication with the chamber, and at least one elastic tab formed in the chamber. A tool can be inserted in the chamber via the aperture and kept there by the elastic tab.

Abstract: A current limiter is connected between a voltage source and the level shifting latch of a level shifter for limiting the driving current for the level shifting latch under a threshold, to thereby reduce the current consumption of the level shifter during logic transition, by which the level shifting latch can be implemented by transistors with shorter channels, thereby downsizing the circuit area of the level shifter. Preferably, the threshold is adjustable for adjusting the output driving capability of the level shifter and speeding up logic transition of the level shifter.

Abstract: There is disclosed a hanging device including a hanger, a stationary connector, a rotational connector, and a tool-connecting element. The rotational connector is connected to a first portion of the tool-connecting element. A tool can be connected to an opposite second portion of the tool-connecting element. When the second portion is separated from the first portion of the tool-connecting element, the second portion and the tool can be rotated relative to the rotational connector. Thus, the tool can be removed from the second portion of the tool-connecting element.

Abstract: A tool head template for a toolbox to organize and hold multiple tool heads has a board (10) and multiple funnel-shaped tubes (12) made of resilient material extending downward from the board (10) to respectively hold multiple tool heads conveniently. Additionally, optional multiple slots (122) are defined in each funnel-shaped tube (12) to allow the inner diameters of the funnel-shaped tubes (12) at and near the distal ends to expand to accommodate insertion of the corresponding tool heads (30).

Abstract: A flexible tool stage device is provided. The flexible tool storage device includes a storage body wich has multiple circular recesses. An insert opening is defined inside of each circular recess, thus a cylindrical constraint tube body is defined between each circular recess and the insert opening corresponding thereto. Each constraint tube body having an internal diameter slightly less than a diameter of an excircle of a shank of a working portion of a tool to be inserted. Each constraint tube body has multiple slots defined along a longitudinal direction thereof and equally distributed thereon. When a tool is inserted through the insert opening, the diameter of the insert opening of the cylindrical constraint body will be enlarged and then a recovery force from the cylindrical constraint body will be urged to stably retain the tool.
