A meeting managing method, a server and a meeting managing system, and relates to the technical field of computers. The method according to the present application includes receiving data of a plurality of participants sent by a first client; binding data of each participant in the plurality of participants with a corresponding electronic-table-card identifier, wherein electronic table cards corresponding to each of the electronic-table-card identifiers correspond to microphones one to one; receiving the voice data sent by the target microphone; according to a target-electronic-table-card identifier corresponding to the target microphone, determining data of the target participant; and according to the voice data and the data of the target participant, generating a meeting document. According to the one-to-one correspondence relation between the participant data, the electronic table cards and the microphones, the data of the target participant corresponding to the voice data is determined, the meeting document is generated accordingly.

A method for estimating the load of a tire supporting a vehicle includes providing the tire, in which the tire includes a pair of sidewalls extending to a circumferential tread, and the tread includes a plurality of tread blocks. A length of the tire footprint is indicated with a first time interval, and a full rotation of the tire is indicated with a second time interval. The first time interval may be indicated by peaks of an amplitude of a tire-based magnetic sensor signal, and the second time interval may be indicated by peaks of the amplitude of the tire-based magnetic sensor signal or by a linear speed of the vehicle. The load on the tire is determined from a ratio of the first time interval to the second time interval at an inflation pressure of the tire. A tire load estimation system is also provided.

An electronic device may obtain a water pressure measurement associated with a charged fire sprinkler system. The electronic device may determine obtained water pressure measurement is indicative of a slow leak or indicative of the fast leak. The electronic device may, in response to determining that the water pressure is indicative of a slow leak, initiate a system recharge in which a fire pump of the fire sprinkler system is activated to attempt to recharge the water pressure.

In one embodiment, a remote monitoring system for a fluid applicator system is disclosed. The fluid applicator system is disposed to heat and pump spray fluid, and to transmit reports including sensed temperatures, pressures, and other operational parameters of the fluid applicator system via a wireless network. The remote monitoring system comprises a data storage server, and an end user interface. The data storage server is configured to receive and archive the reports. The end user interface is configured to provide a graphical user interface based on the reports. The graphical user interface illustrates a status of the fluid handling system, sensed and commanded temperatures of the fluid handling system, sensed and commanded pressures of the fluid handling system, and usage statistics of the fluid handling system.

A pressure sensor includes a substrate, a first pressure sensing element, a second pressure sensing element, and sensor conditioning circuitry disposed on a first surface of the substrate. The sensor conditioning circuitry is electronically coupled to the first pressure sensing element and the second pressure sensing element, thus multiple pressure sensing elements being disposed on a single substrate can reduce material cost and improve the performance of the pressure sensor.

A transmitter arranged in a tire includes a transmitting section, which has a terminal, and a pressure switch. The pressure switch includes a hollow box and a passage that causes an interior of the box and an interior of the tire to communicate with each other. The box includes a conductive deforming portion, which is separate from the terminal when the difference between the pressure in the box and the pressure in the tire is less than a predetermined value and is elastically deformed to contact the terminal when the pressure in the box is higher than the pressure in the tire at least by the predetermined value. The transmitting section transmits a warning signal that causes a tire pressure warning device to issue a warning in response to contact between the deforming portion and the terminal.
