Abstract: A pairing connection method for devices utilizes frequency to transmit information from a source device to a target device. Firstly, the frequency range of a transmitted acoustic signal is defined. The source device then divides the acoustic signal into a plurality of spectrum sections based on the length of the information, and the information per unit length is placed in the corresponding spectrum section, and a speaker is used to send out the transmitted acoustic signal. After the target device receives the transmitted acoustic signal, the target device retrieves the information from transmission frequency of the spectrum sections and establishes a connection with the source device.

Abstract: Methods and systems are described for detecting valve actuation faults in internal combustion engines operating in a skip fire operational mode. In one aspect, a torque model is used to estimate an expected net torque during a selected operating window. The torque model considers an expected torque contribution from each of the cylinders and accounts for the effects of specific skip fire firing decisions that affect the expected torque contribution from each cylinder.

Valve actuation faults can then be identified based at least in part on a comparison of the measured parameter to an expected parameter value that is based at least in part on the expected net torque. With the described approaches, the occurrence of the valve actuation fault can be made within one engine cycle of the initial occurrence of the fault.

Abstract: A compression method featuring dynamic coding for wireless communication in wireless network is used to transmit a packet to clients. An access point (AP) divides a packet into several chunks all having a fixed length, sorts repetition frequencies of all the chunks, and encodes the repeated chunks with Huffman codes. Before transmitting the packet, AP divides the packet into chunks and determines whether there are chunks having been encoded, and transmits the encoded packet and the codes thereof to a specified client and other clients within coverage of transmission. After receiving the encoded packets, the client decodes the encoded packets to recover the original ones. The other clients also store the repeated chunks and the codes thereof The information of the Huffman codes of the repeated chunks needn't be transmitted every time for different clients since other clients may overhear the Huffman codes not intended to send to them.

Based on a comparison of the expected change and the measured change in the engine parameter, a determination is made as to whether an engine error (e.g., misfire) has occurred.
