Abstract: An exemplary apparatus (20), for removing pollutants atop a body of coolant, includes a filter (21), a pollutant removing structure (22), and a pump (23). The filter includes a housing (210), and a filtering unit (211) positioned in the housing for removing the pollutants from the coolant. The filtering unit is separated into a first cavity (2112) and a second cavity (2113) by a partition sheet (213). The partition sheet is spaced apart from a bottom surface of the housing to define a communicating gap (2131) for the first cavity and the second cavity to communicate with each other. The pollutant removing structure is positioned on the filter. The pollutant removing structure includes a removing member (221) for removing the pollutants out of the filter. The pump is configured for pumping the coolant into the first cavity of the filter.

Abstract: A method for sharing reverse channel in trunk communication system includes: step A, establishing a forward channel and one or more in a group: step B, mobile stations in idle state determine a sharing reverse channel that can be used based on information of the sharing reverse channel; step C, the mobile station transmits information through the sharing reverse channel. Furthermore a system for sharing reverse channel in trunk communication system includes: channel establishing means, for establishing a forward channel and one or more in a group; reverse channel determining means, for determining a sharing reverse channel that can be used by a mobile station based on the information of the sharing reverse channel; reverse channel information transmitting means, for transmitting information through the sharing reverse channel. This invention saves the air and physics sources of the system, and reduces the collision probability of the signaling of each mobile station in idle state.

Abstract: An exemplary metal structure (10, 30) includes a base portion (14, 34), a flange (122, 322), and an edge portion (1241, 3241). The base portion defines a circular flanged hole (12, 32). The flange extends from a top surface of the base portion and the flange surrounds the circular flanged hole. The edge portion is configured for connecting an inside surface of the flange and the top surface of the base portion. The edge portion includes an edge surface, and a ratio of a radius of the edge surface (1242, 3242) of the edge portion with respect to a thickness of the base portion is less than 0.4. A method for making a circular flanged hole in a metal sheet (15) is also provided.

Abstract: A method for realizing forward channel sharing in time division communication system, which completes group configuration at the cluster control service center server and modifies the attributes of all the users to enable the users to support multi-user packet MUP service, including: (a) the cluster user initiates a group call; the access network allocates a unique group identifier MACIndex for the group call after receiving the call request from the calling cluster user and informs all of the users within the group about this MACIndex (201); (b) after the communication starts (202), the access network packets the user data of one or more groups with multi-userpacket MUP, packets the user data of each group into one sub-p acket and does scheduling, then transmits the packets through forward channel (203); (c) after receiving the MUP packets from the forward channel, the cluster user looks into the MUP packets forthe sub-packet that matches theMACIndexofits group, thereby realizing group communication (204).

Abstract: A wire arrangement mechanism including a guiding slot and an arranging slot is formed on a fan frame. The guiding slot includes a bottom wall and two holding walls extending therefrom. The arranging slot is defined by an outer frame and a confining portion connected thereto. The arranging slot is staggered from and communicated with the guiding slot.

Abstract: A method for retrieving medical images from various sources and in different formats, to enable the creation of teaching files and research datasets, for the building of a personal medical image library, the method comprising: retrieving a plurality of medical images from various sources; storing the plurality of medical images in a database; generating a database record for the teaching files and research datasets; generating the teaching files and research datasets file; saving the teaching files and research datasets into the database; and generating at least one index of the teaching files and research datasets.

Abstract: An inductor module includes a common inductor core, and first and second inductor windings. Each of the first and second inductor windings has an input end, an output end, and an inductor winding section disposed between the input and output ends. The inductor winding sections are wound on the common inductor core such that the distance between the input end of the first inductor winding and the output end of the second inductor winding is larger than the distance between the output end of the first inductor winding and the input end of the second inductor winding. The output end of the first inductor winding is free of an electrical connection with the input end of the second inductor winding.

Abstract: A temperature control apparatus for a pulse width modulation (PWM) device. The temperature control apparatus includes a temperature detector installed around the PWM device for detecting a present working temperature of the PWM device, and a temperature comparator coupled to the temperature detector and the PWM device for comparing the present working temperature with a maximum limiting temperature and a minimum limiting temperature. When the present working temperature is higher than the maximum limiting temperature, a working frequency of the PWM device will be reduced in a step variation frequency, and when the present working temperature is lower than the minimum limiting temperature, the working frequency of the PWM device will be increased in the step variation frequency.
