Abstract: A method of analyzing source code includes receiving, by a processor, an updated version of a computer program, the updated version including a source code. The method also includes preprocessing, by a compiler, the source code for a target computing platform. Preprocessing the source code by the compiler includes identifying a macro condition associated with one or more computer instructions enclosed by a macro, determining object code corresponding to the one or more computer instructions based on a current value of the macro condition, and generating object code and macro information for output to a debugger, the macro information including one or more breakpoint conditions in the macro.

Abstract: A display panel including a circuit board, a plurality of bonding pads, a plurality of light emitting devices, and a plurality of solder patterns is provided. The bonding pads are disposed on the circuit board, and each includes a first metal layer and a second metal layer. The second metal layer is located between the first metal layer and the circuit board. The first metal layer includes an opening overlapping the second metal layer. A material of the first metal layer is different from a material of the second metal layer. The light emitting devices are electrically bonded to the bonding pads. Each of the solder patterns electrically connects one of the light emitting devices and one of the bonding pads. The solder patterns each contact the second metal layer through the opening of the first metal layer of one of the bonding pads to form a eutectic bonding.

Abstract: A hydrogen-oxygen separation energy-generating system includes a water replenishing chamber, reactors, a reaction body, a metal catalyst reactant and a gas collecting chamber. The system further includes a gas filtering chamber, a buffer chamber, a temporary storage chamber, settling tanks, a screw cleaner, and hardware therebetween, such as communication pipes and valves, to provide an environment-friendly hydrogen-mixed gas. The hydrogen-mixed gas is flammable, and has hydrogen content of 30% or above. Each reactor has a water admitting valve, a water draining valve, a vent valve, and connection valves. The reactors are connected by openable/closable connection valves through gas-delivering pipes such that the metal catalyst reactant in each reactor reacts with water independently, allowing the system to operate around the clock and every day and thereby be conducive to mass production.

Abstract: An intelligent hand washing monitoring system identifies if a user has actually washed every parts of his/her hands and informs the user with washed parts highlighted on a display unit. An image recognition technique is used to determine if the user uses a standard hand washing procedure to wash their hands and suggests to the user which part to wash with respect to the standard hand washing procedure in real time.

Abstract: An electric fan includes a motor driving circuit, a controller, and a stepless speed-change device; the motor driving circuit is electrically connected to a blades-driving motor of an electric fan as well as a power circuit; the controller is electrically connected to the motor driving circuit while the stepless speed-change device is electrically connected to the controller therefore the rotational speed of the blades-driving motor of the electric fan can be adjusted in a stepless manner.

Abstract: A fan includes a motor holding member, and a fragrance giving device; the motor holding member has a slot and several vent holes thereon; the fragrance giving device includes a first shell-shaped member, a second shell-shaped member, and a fragrant unit pressed between the first and the second shell-shaped members; the fragrance giving device is inserted in the motor holding member through the slot in order for the fragrant unit to face the vent holes; therefore, when the fan is running, it can give off fragrant smell, which will be carried with the wind produced by the fan, thus making the room full of fragrant air.

Abstract: Transconductance filter circuits. A transconductor includes two inputs for receiving two differential voltages, and a first output terminal and a second output terminal for outputting two differential signals. A first capacitor array includes at least one first switch capacitor unit controlled by a first signal, and a first equivalent capacitor coupled between the first output terminal and the second output terminal when the first signal is enabled. two second capacitor arrays each includes at least one second switch capacitor unit controlled by a second signal, two second equivalent capacitors respectively coupled between the first output terminal and a ground level, and between the second output terminal and the ground level when the second signal is enabled. The capacitance of the first equivalent capacitor exceeds that of the two second equivalent capacitors connected in serial.

Abstract: A dual-interface card reading device, having a main body and cover plate assembled to form an opening which accommodates insertion of a magnetic card or an IC card, one side of the opening defining a hollow slide groove to enable swiping of a magnetic card or an IC card. A magnetic head extends into the opening to read the magnetic card, and at one end of the hollow slide groove is an IC card contact interface for reading the IC card. A user can thus simultaneously swipe either type of card at an appropriate interface while achieving the effects of small size, low cost, and convenient operation.
