20110068439 | DOUBLE TRENCH RECTIFIER - A high power density or low forward voltage rectifier which utilizes at least one trench in both the anode and cathode. The trenches are formed in opposing surfaces of the substrate, to increase the junction surface area per unit surface area of the semiconductor die. This structure allows for increased current loads without increased horizontal die space. The increased current handling capability allows for the rectifier to operate at lower forward voltages. Furthermore, the present structure provides for increased substrate usage by up to 30 percent. | 03-24-2011 |

20110223575 | SYSTEM AND METHOD FOR LEARNING CONCEPT MAP - A system for creating the learning organizational tool known as a concept map to thereby facilitate learning includes a manipulation-sensing device with a wireless data transceiver, an information integration platform, and a data processing device. The wireless manipulating-sensing device allows users to physically manipulate the concept map and then transmit/receive data related to the results of the physical manipulation via a wireless network. The wireless manipulation-sensing device includes a plurality of conceptual modules for recording data in the process of learning a concept map, a plurality of connecting modules for recording data of the connection relations between the conceptual modules, and a plurality of connecting wires connected between the plurality of conceptual modules and the plurality of connecting modules to form connection relations therebetween. The information integration platform receives the results of the physical manipulation transmitted from the conceptual modules to form concept map information by translation. The data processing device receives the concept map information formed by the information integration platform. In addition, a method for learning a concept map using the system described above is further provided. | 09-15-2011 |
20120214146 | INTERACTIVE LEARNING SYSTEM - An interactive learning system includes a sensing network constituted by a plurality of sensing/transmitting modules, and a transmission network formed by the sensing network and a data processing device. The sensing/transmitting modules sense movements and vibrations thereof and interactive statuses between the sensing/transmitting modules and other sensing/transmitting modules, so as to generate messages that indicate the movements, the vibrations and the interactive statuses, and transmit the sensed messages to the data processing device by the transmission network, for interactive messages to be displayed through a human-machine interface of the data processing device. As such, learners' conceptions can be perceived and shown by the actual operations of the sensing/transmitting modules, which allows teachers to grasp learners' conceptions and thereby increase their interactions. | 08-23-2012 |
