Abstract: A distance measuring device is configured to emit a transmitted wave and detect a reflected wave from an object irradiated with the transmitted wave to measure a distance to the object. At least one of the transmitted wave and the reflected wave is transmitted through a transmission window. A heater is configured to heat the transmission window from an inside of the distance measuring device. A control unit is configured to control energization of the heater according to an inside air temperature which is an air temperature inside the distance measuring device and an outside air temperature which is an air temperature outside the distance measuring device.

Abstract: This axial deviation estimating device estimates an axial deviation angle of a radar device mounted on a mobile body, and includes an acquiring unit, an extracting unit, a device-system coordinates unit, and an estimating unit. The estimating unit estimates an axial deviation angle using a relational expression. The relational expression is an expression that holds between at least one unknown parameter, which includes an axial deviation angle of a coordinate axis of the radar device about a target axis which is at least one of a horizontal axis and a traveling direction axis constituting the coordinate axes of the mobile body, and at least one element included in the device-system coordinates of a road surface reflection point.

Abstract: An in-vehicle device includes a travel planning portion configured to plan, as a travel plan, at least positioning of a vehicle during traveling according to a driving policy; and a verification portion that is configured to: evaluate the travel plan set by the travel planning portion based on driving rule determination information in conformity with a traffic rule; and determine whether to permit the travel plan based on an evaluation result. The travel planning portion is configured to plan positioning of the vehicle according to the driving policy that is set to reduce a frequency of occurrence of a blind area entry situation under which a different vehicle other than the vehicle causes a moving object other than the different vehicle to be positioned within a blind area of a detection range for a periphery monitoring sensor that is configured to monitor surroundings of the vehicle.

Abstract: A motor includes a stator having a stator core and a coil. The stator core has a plurality of teeth arranged at intervals in a circumferential direction. The coil is formed of an electrically-conductive winding wound around the teeth. Moreover, the motor also includes a rotor having magnets arranged in radial opposition to the stator core and at intervals in the circumferential direction. The rotor is configured to rotate upon supply of electric current to the coil. Furthermore, the motor also includes a sensor arranged in a circumferentially intermediate area between a circumferentially-adjacent pair of the teeth in an axial view. The sensor is configured to detect magnetism of the magnets.

Abstract: An axis deviation angle estimation device estimates a vertical axis deviation angle of a radar device based on roadside object information including information on a plurality of reflection points on a roadside object and road surface information including information on a plurality of reflection points on a road surface. The vertical axis deviation angle is an angle of deviation of an actual mounting direction from a reference mounting direction in a vertical direction. The actual mounting direction is an actual direction of the radar device, and the reference mounting direction is a direction of the radar device when the radar device is mounted in a reference state.

Abstract: A power system includes a battery module and a battery ECU. The battery module includes multiple battery stacks. Each of multiple battery stacks includes multiple battery cells, multiple detectors which independently detect physical values of the multiple battery cells, respectively, and multiple individual communicators which wirelessly output detection results of the multiple detectors. Each of the multiple individual communicators communicates a radio signal wirelessly to and from a general monitor. The multiple battery stacks and the general monitor are accommodated in a storage space in a housing having electromagnetic shielding performance. A shield is also accommodated in the storage space while facing a communication hole formed on the housing.

Abstract: A server including a storage and a controller is communicably connected with a communication terminal. The storage is configured to store a processing data and an analysis data for each of a plurality of analysis targets. The processing data relates to a processing condition for forming a concavo-convex structure on a detection substrate to be used in performing a spectroscopic analysis. The analysis data is used to analyze the analysis target from a spectroscopic spectrum of the analysis target obtained by the spectroscopy analysis. Upon receiving a signal requesting the processing data, the controller is configured to select the processing data corresponding to the analysis target and transmit the selected processing data to the communication terminal. Upon receiving a spectroscopic spectrum, the controller is configured to use the analysis data to analyze the spectroscopic spectrum.

Abstract: A valve device includes: a seal member that is slidably in close contact with an outer peripheral surface of a rotation shaft; and an annular attachment ring that attaches the seal member to a housing. The seal member has a first-side plate part and a second-side plate part sandwiching and holding the seal member in an axial direction of the rotation shaft. An inner peripheral end of the second-side plate part is positioned radially outside beyond an inner peripheral end of the first-side plate part. An outer surface of the first-side plate part includes an outer peripheral-side region positioned radially outside beyond the inner peripheral end of the second-side plate part and an inner peripheral-side region positioned radially inside beyond the outer peripheral-side region. The outer peripheral-side region is positioned on a first side of the axial direction with respect to the inner peripheral-side region.
