Abstract: Embodiments of the present disclosure provide a region-specific events account that is used as a central place to store the events shared by consumers of shared applications in that region. Use of such an account helps reduce the operational burden of a provider of the applications as they do not need to determine which accounts have shared events for each different consumer. The provider only needs to login to the events account which is in the same region as the consumer and can query all shared events from different applications that are being used in that region. Also, since the provider can designate an events account in each region, the shared events could be directly ingested into the events account without traveling to a different region.

Abstract: A resource information determining method and device, a storage medium, and a user equipment. The method includes: determining a frequency domain position of a PRB with a minimum index of a synchronization signal block; determining a position of an initial active downlink BWP according to the frequency domain position of the PRB with the minimum index of the synchronization signal block; determining a position of a CORESET of a first type of PDCCH, wherein the position of the CORESET comprises the frequency domain position of the PRB with the minimum index of the CORESET and the number of the PRBs of the CORESET, or a position of a bitmap-based PRB of the CORESET. By means of the solution of the present invention, the user equipment can obtain resource configuration of the initial active downlink BWP and resource configuration information of the first type of PDCCH in an NR unlicensed spectrum.

Abstract: A method and apparatus for transmitting uplink control information (UCI) for Long Term Evolution-Advanced (LTE-A) using carrier aggregation is disclosed. Methods for UCI transmission in the uplink control channel, uplink shared channel or uplink data channel are disclosed. The methods include transmitting channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (ACK/NACK), channel status reports (CQI/PMI/RI), source routing (SR) and sounding reference signals (SRS). In addition, methods for providing flexible configuration in signaling UCI, efficient resource utilization, and support for high volume UCI overhead in LTE-A are disclosed.

Abstract: The disclosure provides an adjustable device including plates and at least two adjustable modules connect with two adjacent of the plates. The adjustable module can stretch or shrink to change a distance between plates. The disclosure also provides an adjustable storage box including an upper cover and a lower cover. A storage space is formed by the upper cover and the lower cover and for the accommodating of the adjustable device. When the upper cover moves upward relative to the lower cover, the adjustable modules changes from a compression state to a stretch state and increase a distance between plates. Whereby, it is easy to pick and place object when a distance of two adjacent plates increases. The overall volume of the adjustable device is reduced when a distance of two adjacent plates decrease, thereby saving the working space.

Abstract: The embodiment of the present disclosure provides a welding device, a welding method, and an installation and debugging method thereof. The welding device includes a baseboard, comprising: a left welding nozzle and a right welding nozzle, a power shaft, a bidirectional moving wheel, and two welding nozzle connecting shafts, wherein the welding nozzle connecting shafts are connected to the left welding nozzle and the right welding nozzle respectively, and the bidirectional moving wheel which is driven by the power shaft drives the two welding nozzle connecting shafts to move towards or away from each other.

Abstract: The present disclosure provides a hair removing device, including: a reflector, a light source, a first light-transmitting body, a heat dissipation base and a refrigerating member. The light source is arranged inside the reflector and can emit light. The reflector can reflect light, such that the hair removing device can emit light to remove the hair from the skin. The first light-transmitting body and the reflector cooperatively define a cavity to receive the light source. A body of the light source is suspended in the cavity. Two sides of the heat dissipation base are thermally coupled to the reflector and the refrigerating member respectively.
