摘要： A DC-DC converter includes a variable frequency oscillator, a control system and a power train. The DC-DC converter is well suited for use in a cell phone. The control system uses the output of the oscillator to control the power train. The oscillator varies its frequency as a function of a pseudo random number generator, thereby reducing electromagnetic interference caused by ripple in the output of the DC-DC converter.

摘要： The present invention provides a mobile industry processor interface MIPI clock frequency configuration method and apparatus. When a radio frequency band used by a device on which an MIPI is located changes, an MIPI clock frequency is determined according to radio frequency band information, where the radio frequency band information includes the radio frequency band currently used by the device, and the determined MIPI clock frequency causes no interference to the radio frequency band currently used by the device; and an MIPI clock frequency of the device is configured as the determined MIPI clock frequency. According to the technical solutions in the present invention, when a radio frequency band of a device changes, an MIPI clock frequency causes no interference to communication of the device, thereby improving communication quality and stability of the device.

摘要： A wireless communication device includes a transmission data generator which segments transmission data into a plurality of subslots and then generates a plurality of slots each including a predetermined number of subslots from among the plurality of subslots, and a transmitter which transmits the plurality of slots generated by the transmission data generator. The time length T 1 of the subslots is equal to or smaller than an oscillator stopping time which is determined on the basis of a change in voltage of a commercial AC power supply.

摘要： A mobile device may include a digital data driver and digital data receiver for communication of digital signals within the mobile device at a selected clock rate. The mobile device may also have a device external for the digital data driver and digital data receiver for communication of external signals, such as radio-frequency signals, to and from the mobile device. To avoid interference of frequency harmonics of a digital signal with such external signals, the digital data driver may be configured to control the digital signal based on the frequency of the external signals, such that interference of the external signal by spectral content of the digital signal is minimized, while maintaining the selected clock rate.

摘要： An arrangement, system and method for reducing the effect of interference at radio frequencies in an electronic price label system. The arrangement includes an electronic price label system, which includes a base station equipped with at least a radio transmitter and a radio receiver as well as a set of electronic price labels that receive and reflect back radio signals from the base station. The electronic price label system is connected to an electronic article surveillance system which includes a detector device which is able to detect electronic article surveillance tags, and which electronic article surveillance system further includes an activation device for changing a state of the detector device between an activated-state and a deactivated state. The electronic price label system is configured to start transmitting transmissions from base stations and/or electronic labels only when the detector device of the electronic article surveillance system is in the deactivated state.
