Abstract: A combined electric tool coordination system includes a main tool (4) and an auxiliary tool (1). The main tool (4) and the auxiliary tool (1) coordinate for working. A load detection module (E1) is used to detect a load parameter that is generated when the main tool (4) operates, and send the load parameter to a central control module (E2). The central control module (E2) adjusts output power of the auxiliary tool (1). The central control module (E2) controls power of the auxiliary tool (1) to increase as the load parameter of the main tool (4) increases and decrease as the load parameter decreases.

Abstract: Amorphous two-dimensional graphene-like carbon films provide benefits to a variety of applications due to advantageous electrical, mechanical, and chemical properties. Methods are provided to efficiently and cheaply create high-quality amorphous two-dimensional carbon films with embedded graphene-like nanocrystallites using coal as a precursor. These methods employ solution-phase deposition of coal-derived graphene-containing quantum dots followed by relatively low-temperature annealing/crosslinking of the quantum dots to form a single two-dimensional layer of carbon that includes a plurality of randomly-oriented discrete graphene domains connected to each other via amorphous carbon regions. Multi-layer films can be easily created by repeating the deposition and annealing processes. Two-dimensional carbon films formed in this manner exhibit improved properties when compared to crystalline graphene sheets and have properties especially suited to use as the storage medium of memristors.

Abstract: An electric tool control circuit includes a central control module, a motor drive module, a motor, and a working parameter detection module. The working parameter detection module can detect and communicate a parameter to the central control module related to a load on the motor detected during running of the motor. The motor drive module is separately electrically connected to the motor by using first and second switch modules, and the motor drive module controls the first and second modules to be discontinuously on and off to thereby reduce variation of a speed of the motor caused by a variation of the load on the motor. The status of the first and second switch modules being on and off are always contrary. A related method is disclosed.
