Learning support server, learning support system, and learning support program

A learning support server (10) provides a student terminal used by a student (for example, each of a plurality of student terminals (21 - 23, 31 - 33) with test information for displaying a test screen through a communication network (40). The test screen includes a display region for displaying a test problem, an answer column, and a test progress state of other students. The learning support server (10) is provided with a history information DB (12) for storing history information including a test problem, a student, an answer by the student and the performance of the student. The learning support server (10) receives student information associated with a student who newly takes a test; creates test information on the basis of the received student information and the history information; and transmits the created test information to the student terminal. Thereby, the learning support server provides a learning support technique capable of improving the learning motivation of a registered user (student) and enhancing learning effects.

Portable automobile diagnostic tool

A portable automotive diagnostic tool (30) for receiving information from an automotive computer of a vehicle. The portable automotive diagnostic tool (30) is battery powered. The portable automotive diagnostic tool (30) comprises a microcontroller (31), a display (32), a keypad (33), a flash memory (34), a SRAM (35), a battery backup circuit (36), a ROM (37), a UART (38), and a port (39). Automotive codes for configuring the portable automotive diagnostic tool (30) are stored in flash memory (34). The automotive codes are compressed to increase storage to the flash memory (34). The flash memory (34) is non-volatile and retains the automotive codes when power is removed. The automotive codes are updated by writing new automotive codes to the flash memory (34). Information or data received from an automotive computer is stored in SRAM (35). The battery backup circuit (36) powers the SRAM (35) to maintain the information to be taken to a different location when the power is turned off.
