Abstract:
An electronic device and an operating method thereof are provided, wherein the electronic device includes a first infrared sensor and a display unit for displaying a frame. In the present operating method, an individual operation is defined for the first infrared sensor, wherein the individual operation is to turn the frame over or to move a position of a cursor displayed in the frame. If a period for which the first infrared sensor has sensed infrared radiation from an object is shorter than a first predetermined value, the first infrared sensor is determined as being temporarily hidden and the individual operation is performed.

Including: banknote serial number recording step, that is to convert the banknote serial number into image signal by using image capture device; banknote serial number recording decoded step, i.e. processing the banknote serial number image signal by filtration of image signals, A/D conversion, synchronizing separation and then stored in memory unit; banknote serial number digital signal processing step, the signals from image memory unit are processed for recognition, the bundle code and banknote serial number are stored into digital memory unit and output for later use; the comparison banknote serial numbers read-in steps, reading banknote serial number from a certain bundle code to be compared, then sent to read-in memory unit; comparison step for the banknote serial number to be compared and newly recording banknote serial number comparison, to compare the newly recording banknote serial number with each of the banknote serial number from the reading-in memory until there is a match and an alarm signal is sent out. Application of this invention can impose a strict strike upon the crimes such as robbery of money from bank saves, robbery of cash transport vehicles or kidnaps, and cash counterfeiting.
Abstract:
There is disclosed a method of indicating a resource occupancy scheme and processing a resource occupancy scheme indicator so as to enable a UE to be aware a resource occupancy scheme of the network side and avoid an unnecessary power waste and unnecessary interference, and in the method, a base station generates a corresponding resource indicator for a resource occupancy scheme of a legacy control resource area and an enhanced control resource area in each downlink subframe to be transmitted in a specific periodicity and sends the resource indicator to a UE in a resource indication message, and the UE determines from the obtained resource indicator the resource occupancy scheme of the legacy control resource area and the enhanced control resource area in each downlink subframe to be transmitted in the specific periodicity and performs a corresponding resource handling mode, so that the UE can blindly detect in PDCCH common and user spaces or receive control information carried on PHICH resource at an accurate position to thereby avoid an unnecessary power waste of and unnecessary interference to the UE due to blind detection or reception and improve effectively the performance of a system.
Abstract:
Examples of the present disclosure provide a method for transmitting downlink control information to effectively support the two transmission modes of the E-PDCCH. The base station configures the localized E-PDCCH resource and the distributed E-PDCCH resource. The user terminal detects the DCI in the search space corresponding to the localized E-PDCCH resource and the search space corresponding to the distributed E-PDCCH resource, so as to obtain the downlink control information transmitted by the base station.

The invention relates to a continuous polymerization process for preparing a random ethylene interpolymer which comprises: (A) polymerizing ethylene, and an α-olefin comonomer selected from propylene and/or 1-butene, and mixtures thereof, under continuous random polymerization conditions in the presence of single site catalyst system employing an ionic activator having cyclic ligands shielding a central charge bearing atom, at a temperature of 140° C. to 250° C. at a conversion of ethylene of 80 to 99% and a comonomer conversion of from at least 20%; and (B) devolatilizing the polymer to provide an ethylene copolymer having a density of from 0.85 to 0.92 g/cm3, an MI of from 0.01 to 100 g/10 min and an I21/I2 of from 30 to 400.
Abstract:
The present invention discloses a method and device for transmitting downlink information in a multi-carrier aggregation system. The Method includes: a base station side sends a downlink subframe to a terminal side, wherein, the physical downlink control channel (PDCCH) in the downlink subframe is used for bearing more than one piece of downlink control indicating information and the carrier scheduling indicating information corresponding to each downlink control indicating information. It solves the problem in the prior art of indefinite identification at the terminal side because the length of DCI may be same due to the difference of the bandwidths of carriers in the carrier aggregation system.
Abstract:
An input method applicable for inputting into an electronic device, which includes the steps of capturing a lip motion of a person; receiving an image of the lip motion; encoding the lip motion image to obtain a lip motion code; comparing the lip motion code with a plurality of standard lip motion codes to obtain a first text result matching the lip motion code; and displaying the first text result on the electronic device if the first text result is obtained. If the first text result is not obtained, the method may further include activating an auxiliary analyzing mode for the electronic device for recognizing a facial expression, a hand gesture, or an audio signal to be inputted. The input method can diversify input methods for the electronic device.
