The invention discloses an information processing system, an information processing method and a computer readable medium, and the information processing system is provided with a processor. When an instruction to switch a mode in which a job is executed from a first mode to a second mode in which the job is executed under an operation condition in which an operation sound is smaller than that of the first mode is issued, the processor switches the mode from the first mode to the second mode. And notifying a user indicating execution of a job having the possibility of executing at least a part of the second mode of a situation in which an indication of mode switching is issued.

This invention relates to a method for manufacturing an optical film, an optical film, a polarizer, and a liquid crystal display device. The objective is to provide a method for manufacturing a wide-width optical film with low retardation values ​​in both the in-plane and thickness directions, and to suppress display unevenness caused by environmental variations in the display device, using a plant-derived resin. The method for manufacturing the optical film of this invention is characterized by comprising: a step of forming a strip film from a cellulose ester resin containing a total acetyl substitution degree of 2.30 to 2.60 and a sugar ester having a furanose or pyranose structure; and a step of stretching said strip film, wherein the retardation value R... o The range is 0–10 nm, R t The process of stretching the long strip film, with a wavelength of -10 to 10 nm, includes the following steps: a first step to obtain a first stretched film; and a second step to further stretch the first stretched film to obtain a second stretched film, wherein the stretching temperature of the second step is in the range of 190 to 220°C.

The present invention provides a real-time positioning method and device integrating laser radar and IMU sensor information, with unscented Kalman filtering as the framework, using high-frequency inertial measurement unit data to predict the motion of an unmanned platform, and caching the data; after receiving the laser radar data with a timestamp, the point cloud matching module uses the predicted posture as a priori information, matches based on the normal distribution transformation and the known point cloud map, and obtains delayed global positioning information; uses the positioning information to update the unscented Kalman filter at the time of the laser radar timestamp, calibrates the prediction error of the inertial measurement unit, and uses the cached high-frequency inertial measurement unit data to re-predict based on the positioning information, so as to achieve a low-latency, high-frequency positioning effect. The method can achieve high-frequency, low-latency real-time positioning, bringing better control effects.

A control system (1) for causing a vehicle to by using a magnetic marker (10) laid on a road surface forming a traveling road (100) of the vehicle (2) includes a magnetic sensor array that identifies a deviation in a lateral direction with respect to the magnetic marker (10) and a control unit that that converts the deviation in the lateral direction with respect to the magnetic marker (10) into a deviation of a control point in the lateral direction with respect to a target path and controls a steered angle of the vehicle (2)so that the deviation of the control point in the lateral direction is brought closer to zero. By setting the control point at a position ahead of the magnetic sensor array in a longitudinal direction of the vehicle by a distance obtained by adding an offset distance to a distance obtained by multiplying a speed of the vehicle (2) by a predetermined time, high followability to the target route is achieved.

A rotary compressor is provided that may include a casing having an oil storage space; a cylinder; a main bearing and a sub bearing; a rotary shaft; a roller having a vane slot and a back pressure chamber; and at least one vane. An oil supply hole that communicates the back pressure chamber with the oil storage space may pass through the main bearing or the sub bearing, or through the roller. Accordingly, as high-pressure oil is supplied directly to a rear end surface of the vane, it is possible to increase efficiency of the compressor by increasing a back pressure on the vane and suppressing a delay in starting the compressor, and it is also possible to reduce collision noise and wear in the vane and the cylinder by suppressing vibration of the vane.
