A method for communicating between motorized power tools includes establishing, using a physical interface of a first power tool, a wireless radio link between the first power tool and a second power tool. The first power tool has a first motor and the second power tool has a second motor. A signal is received over the wireless radio link, via the physical interface, at the first power tool from the second power tool using a first wireless communication protocol. The signal includes an identifier. The second power tool is verified as authorized to send the signal to the first power tool based on the identifier. A tool component of the first power tool is controlled responsive to the signal.

A system comprising a processor and a computer readable memory coupled to the processor, the computer readable memory configured with a page processable by page processing code. The page can be configured to generate a set of random connection data usable by a local server program instance to verify that a connection request is from the page, launch the local server program instance, provide the set of random connection data to the local server program instance, create a client socket instance, send a connection request to the local server program instance to establish a connection between the client socket instance and a server socket instance of the server program instance and based on an acceptance of the connection request by the server program instance, complete the connection. The connection may be usable for bi-directional communication between the page and local server program instance.

The present invention disclosed an operation data accessing device comprising a non-internet protocol connection module, a storage module, and a processing module. The operation data accessing device communicates with the operation data storage device through the non-internet protocol connection module. A first logical disk and a second logical disk are established in the operation data storage device. The first logical disk stores the operation data, the second logical disk stores the mapping operation data, and the mapping operation data corresponds to the operation data of the first logical disk. The storage module stores a set of program code. The processing module calls the program code stored in the storage module and performs the operations of establishing a link logical disk that establishes a data link channel for capturing the mapping operation data when the processing module detects that the non-internet protocol connection module is enabled.

The present application discloses a data processing method and apparatus for performing protocol parsing in the cloud. A specific implementation of the method includes: acquiring a slave station data reading rule table that is configured by a user in the cloud; downloading the slave station data reading rule table to a gateway in a slave station; receiving slave station data that is associated with the slave station and that is read by the gateway according to the slave station data reading rule table; parsing the slave station data according to a parsing table in the cloud preset by the user; and processing the parsed slave station data. This implementation implements the processing of data of different communication protocols in the cloud.

The Data Polarization process is completed on computer systems to make binary data information streams more efficient. The process does this by polarizing the binary segments and adding a signature to indicate how the segments were polarized for unpackaging. Polarizing in Data Polarization means that in all of the binary information segment, either all of the zeros are turned into ones, and ones turned into zeros. Afterwards, after computations or transmissions with the data package, with the signature, the information can be correctly interpreted and unpackaged. This helps computer systems use less energy in transmission and computation as less ones, or bursts of energy, are being used overall in the system, because of the optimized segments. This has many uses in a variety of computer systems including undersea cable relays, quantum computers, or Bitcoin miners.

A system and method for communicating with power tools using a universal protocol. The universal protocol may be implemented using a universal core module that is installed across a variety of power tools and other devices to enable communications therewith. Communications to and from the power tools are translated to a universal protocol once received. The translated communications are handled by the universal core module of a particular tool according to a set of rules. In response, the universal core module outputs communications according to the universal protocol and the set of rules, which may be translated to another protocol for receipt by components of the tool or an external device. The communications may be used, for example, to obtain tool performance data from the tools and to provide firmware updates.
