Patent EP-4312006-A1 (EP)
Inventor: LOECKLIN EBERHARD LOTHAR
IPC: G01J3/28
Filed: 2023-07-26
Abstract: A monochromator apparatus for an optical spectrum analyzer (OSA) may include a diffraction grating and a sensor. For calibration of the monochromator, an optical signal may be received and a 0<sup>th</sup> order diffracted signal and an angle of the 0<sup>th</sup> order diffracted signal may be detected, where the 0<sup>th</sup> order diffracted signal is obtained by diffracting the optical signal on the diffraction grating. The angle of the 0<sup>th</sup> order diffracted signal may be set as a reference angle and a next order diffracted signal and an angle of the next order diffracted signal detected. A wavelength of the next order diffracted signal may be determined based on the reference angle and the other angle of the next order diffracted signal using a look-up table or a grating equation-based computation. The calibration may be performed for each sweep of the OSA, at the beginning of a measurement, periodically, or on-demand.

Abstract: This application relates to the technical field of circuits, and provides an electronic device, a pull-up circuit, and a method for suppressing a POP sound of an earphone. The electronic device includes a controller, a pull-up circuit, and a Type-C interface. An output terminal of the pull-up circuit is configured to be connected to a Type-C plug of the earphone through a MIC pin of the Type-C interface. The controller is configured to control the electronic device to be disconnected from an audio path of the earphone, control an access resistance value of the pull-up circuit to be a first resistance value, and identify normal/reverse insertion of the earphone based on a voltage of the MIC pin of the Type-C interface when the earphone is inserted into the Type-C interface of the electronic device through the Type-C plug. The controller is further configured to control the access resistance value of the pull-up circuit to be a second resistance value after the identification is completed, and the first resistance value is greater than the second resistance value. In this way, the electronic device can normally identify normal/reverse insertion of the earphone while eliminating the POP sound when the earphone is reversely inserted.

Abstract: A water-conserving toilet is disclosed and includes a bowl (36) for receiving waste and a waste outlet (40) extending laterally from the bowl (36) and defining a first, shallow trap arranged so that a relatively shallow body of liquid is normally retained in the bottom of the bowl (36) for preventing gaseous flow through the trap. A flush system is provided and is arranged, when operated, to deliver a charge of flushing liquid into the bowl (36) in a direction to cause said body of liquid to be discharged through said outlet (40). A waste holding tank (42) communicates with said bowl outlet (40) for receiving waste from the bowl (36) and the holding tank (42) has an outlet (44) extending outwardly from the tank (42) and adapted for connection to a sewer inlet. The holding tank outlet (44) defines a second trap of substantial height capable of preventing reverse flow of sewer gas into the holding tank (42) in use and the holding tank (42) and second trap are arranged to contain a volume of liquid substantially in excess of the volume discharged from the bowl (36) at each flush. A flexible diaphragm (112) extends across the holding tank (42) above the level at which liquid enters from the bowl (36) and is sealed to the tank in gas-tight fashion. The diaphragm (112) is adapted to flex upwardly and accommodate air displaced as liquid enters the tank (42) from the bowl, (36) so as to minimize air resistance to flushing of liquid from the bowl (36).

A continuous air stream (58,59,61) downstream of the nozzles spreads the lubricant while a continuous air stream upstream of the nozzles cleans the chain (10). In addition, an hour timer (70) is provided to operate the lubricating system periodically while a minute timer (71) is provided to interrupt operation of system after a selected number of cycles and to reset the hour timer (70) for a subsequent lubrication operation.
