Abstract: A vehicle operation detection device includes processing circuitry configured to output a command causing an opening-closing body of a vehicle to open and close in reference to capacitances of sensor electrodes arranged so as to form a row. The processing circuitry is configured to determine that a first operation has been performed when one of the sensor electrodes of which the capacitance increases is sequentially shifted in a first direction from an operation start electrode and determine that a second operation has been performed when the shifting is performed in a second direction. The sensor electrodes include an adjacent electrode adjacent to the operation start electrode. The processing circuitry is configured to determine that the capacitance of the adjacent electrode has increased when the capacitance becomes greater than or equal to a second determination value that is greater than a first determination value.

Abstract: A variable magnification optical system consists of, in order from an object side to an image side, a first lens group, a second lens group, and a subsequent lens group. The variable magnification optical system satisfies a predetermined conditional expression for a partial dispersion ratio related to F line, C line, and a wavelength of 1970.09 nm, a d-line back focus of the variable magnification optical system at a telephoto end, a back focus in any one wavelength from a wavelength of 1300 nm to a wavelength of 2325.42 nm at the telephoto end, and a d-line focal length of the variable magnification optical system at the telephoto end.

Abstract: A communication control method for preventing contention for an originating telephone number among a plurality of terminal devices. A terminal device directly connected with a telephone line is provided with means for setting whether or not to execute an originating telephone number receiving sequence at the terminal device and, when the execution of the originating telephone number receiving sequence is set for the terminal device, the sequence is executed at the device and a connection between the telephone line and the other terminal device is cut off; when the execution of the sequence is not set for the device, the sequence is not executed at the device and the other terminal device is connected with the telephone line to execute the sequence at the connected other device.
