Abstract:
Provided are a system and method for detecting air pollution, characterized by using an air pollution detecting device for detecting air pollutants, using a positioning device for locating the air pollution detecting device, and enabling a data transmission device to transmit air pollution data and position data to a data analysis and management device via a network system, and then enabling the data analysis and management device to perform analysis and management process on the data; accordingly, perceiving air pollution status at each area and thus proving air pollution information and improvement to air pollution areas in a shorter time.
Abstract:
A mouse device includes two buttons, a detection circuit, and a shell. The two buttons includes a conductor and a detection circuit electrically coupled to the electrical conductor. The detection circuit is configured to detect human micro-electrical signal transmitted from the electrical conductor and for generating a corresponding pulse. The signal processing circuit is configured to receive the pulse generated by the detection circuit, and to convert the received pulse into a control signals. The shell is configured to support the buttons and house the signal processing circuit.
Abstract:
A pad for soldering a lead of an electronic element includes a solder portion and one or more non-contiguous extending portions. The solder portion is configured for positioning the lead of the electronic element thereon and has a size and shape substantially equal to the size and shape of the footprint of the lead. The one or more non-contiguous extending portions extending from the solder portion and configured for providing additional solder paste in the soldering process. The pad can limit the position of the leads of the electronic element in the solder portion, thus ensuring accurate positioning of the electronic element.
Abstract:
An data transmission adjustment system that comprises a server and a plurality of data transmission devices within a sensing region. The server adapts to receive a sensed data from at least one data transmission device, define a timeline, divide the timeline into a plurality of monitoring periods, calculate a ratio of the number of the monitoring periods that have received the sensing data from the data transmission device within the sensing region or not to the number of all the monitoring periods, and broadcast at least one message to the data transmission devices within the sensing region according to said ratio.

Abstract:
A mobile communications device accompanying with a radio frequency (RF) unit is provided for roaming Public Land Mobile Network (PLMN) selection. In the mobile communications device, a processing unit directs the RF unit to register to a plurality of PLMNs one at a time for reception of at least one Short Message Service (SMS) text message from the currently registered PLMN, and then retrieves service charging information from the SMS text message for each of the PLMNs. Also, the processing unit directs the RF unit to register to one of the PLMNs for obtaining mobile services therefrom according to the service charging information.

Abstract:
The present invention discloses a volunteer search server, comprising a receiver, a database, an analyzer and a transmitter. The receiver is for receiving a request message from a requester, wherein the request message contains the location information of the requester. The database is for storing a matching mechanism and the location information of a plurality of volunteers. The analyzer is for exercising the matching mechanism to search at least one suitable volunteer according to the request message, wherein the matching mechanism considers both the location information of the requester and the volunteer. The transmitter is for transmitting a designate message to one designated volunteer. Additionally, the present invention discloses a search method of the volunteer search server and a volunteer search system thereof.
