Abstract: An aza-ergoline derivative and a preparation method therefor and an application thereof. The derivative has a structure as shown in formula (I). The aza-ergoline derivative has good affinity, agonistic activity or selectivity to a dopamine D2 receptor.

Abstract: A noise filtering device, method, and chip for a dynamic vision sensor (DVS), and an event-driven vision device, and an electronic device are provided. In order to meet multi-dimensional requirements of a denoising solution such as power consumption, delay, storage resources, calculation resources, denoising effect, applicable range of noise types, and hardware implementation difficulty, in this disclosure, global space-domain and time-domain informations are simultaneously aggregated in a shift register, or latest time-domain informations are collected through a space domain, and finally, whether an event generated by a DVS is a noise event is judged on the basis of clustering of space-domain informations and the time-domain informations. While achieving excellent denoising performance, this disclosure has outstanding advantages in the aforementioned multiple dimensions because of advantages of parallel and simple calculation and no dependence on a DVS resolution, etc.

Abstract: A mobile communication terminal, which includes a front panel, a bone conduction device and a motherboard is disclosed. The front panel is configured with a screen. The bone conduction device is in contact with the screen or the front panel, and a contact point of the bone conduction device is connected with the motherboard. The bone conduction device receives an electronic signal transmitted from a processor of the motherboard through the contact point, and transmits the electronic signal to the screen or the front panel through a place of contact therebetween to activate vibrations of the screen or the front panel, thereby transmitting audio to a user. Since the bone conduction device is used in the present disclosure to replace a receiver for transmitting electronic signals, audio can be transmitted to the user through the bone conduction device in a normal manner regardless of whether the mobile communication terminal is in a status of an upright position or in a status of an inverted position.
