Abstract: A method and device for incident situation prediction. Using the method, a list of objects of interest is generated and stored in a call controller, where each object of interest in the list of objects of interest is associated with at least one of a plurality of incident types. The call controller receives an image stream of an incident and classifies the image stream as one of the plurality of incident types. The call controller selects a subset of objects of interest from the list of objects of interest, the subset of objects of interest associated with the one of the plurality of incident types. The call controller determines whether the image stream includes an object from the subset of objects of interest and generates a notification associated with the object. The notification is transmitted to a set of incident scene devices associated with the incident.

Abstract: In a direct mode two-way radio frequency communications system having a plurality of direct mode traffic channels, a first direct mode subscriber unit (DMSU) monitors a preconfigured direct mode control channel (DMCC), the DMCC being a channel that is monitored by all DMSUs that are idle in the system, and which is time divided into slots including traffic channel status slots (TCSSs), each TCSS associated with another physical direct mode traffic channel (DMTC) in the communication system. Responsive to detecting a request to initiate a new call, the DMSU selects a first DMTC on which to transmit the call, transmits during the next TCSS of the DMCC associated with the selected DMTC a header indicating the first DMSU's intention to transmit a new call on the selected DMTC, and subsequently switches to the selected DMTC and transmits the new call.

Abstract: A repeater receives a first group message directed to a talk group. The repeater assigns a first unique message identifier including a generated first sequence number to the first group message. The repeater broadcasts the first group message with the first unique message identifier and the unique talk group address to the talk group. The repeater later receives a second group message directed to the talk group, generates a second sequence number from the generated first sequence number, assigns a second unique message identifier including the second sequence number to the second group message and broadcasts the second group message to the talk group. The first sequence number and the second sequence number may be used by a receiving radio of the talk group to determine if the radio failed to receive one or more group messages or if a received group messages is a duplicate message.

Abstract: A radio receives a call including a call include bitmask (CIB). The radio retrieves a call include list (CIL) that, for each bit position in the CIB, maps the bit position to one of a radio identifier, a talk group identifier, and a sub-CIL. The radio determines that one bit position in the CIB is set to a value indicating that a radio associated with a radio identifier mapped to the bit position in the CIB via the CIL or to a talk group identifier mapped to the bit position in the CIB via the CIL are to be included in the call. The radio matches its identifier to the radio identifier mapped to the bit position or matches a talk group to which it subscribes to the talk group identifier mapped to the at least one bit position and unmutes the call.

The method has advantages of being simple to manage and of low cost, which is suitable for large-scale industrial production. The present invention further provides a cocrystal of (1S)-1-[4-chloro-3-(4-ethoxybenzyl)phenyl]-1,6-dideoxy-D-glucose and L-proline, and preparation method and uses thereof.

Abstract: The present invention relates to a method and system for correcting acquisition channel of merging unit in power system which belong to the technical field of simulation data collection of power system. The present invention performs data acquisition of each channel firstly, and the acquired data is continuous and effective frequency data, then the collected data is stored to their respective backup areas, and the data storage is stopped until the amount of stored data is up to a predetermined value required for correcting, the data is corrected finally within the respective backup areas of each channel which stops the data storage. The correction process is performed by using corresponding correction module. The method for the channel correction improves the efficiency of channel correction greatly, reduces the correction error, improves the correction precision, and has more simple and convenient operation in comparison to the conventional method for channel correction by modifying hardware parameters.

Abstract: A resident measurement system for a charge level of a blast furnace includes a chamber, a servo system, a distance measurement unit, and a cooling-cleaning unit. The chamber is combined with a lateral furnace wall of the blast-furnace, covers an opening of the furnace wall, and has a pivoting hole. A pivot of the distance measurement unit is pivotally disposed at the pivoting hole, and the distance measurement unit is driven by the servo system to perform a motion with the pivot as a movement center, so as to measure the charge level. The cooling-cleaning unit is used to supply a high-pressure gas, which flows through the distance measurement unit to perform cooling and cleansing operations.
