Abstract: PURPOSE: A method for generating and processing tasks in an IPC(Inter-Processor Communication) simulator is provided to carry out the maximum IPC performance measurement with a low error by matching the internal conditions of an IPC simulator with the transmitting/receiving states of generic IPC data more approximately. CONSTITUTION: If an IPC sender_7 task(100a) in an IPC simulator transmits 'sequence 1' to the IPC receive_7 of a receiving task(200)(300a), a response for 'sequence 1' is sent to the IPC receive_8(100b) of the IPC simulator from the IPC sender_8 of the receiving task(200). The IPC sender_7 task(100a) creates a task for each signal(sequence 2-5) and sends it to the IPC receive_7(302a,304a,306a,308a). The receiving task(200) provides a response for each signal so that the IPC receive_8(100b) of the IPC simulator can receive it immediately(302b,304b,306b,308b).

Title: observing able oblique area for side mirror of vehicles
Inventor: LIM TAE SIK
IPC: B60R1/08
Filed: 2001-02-26
Abstract: PURPOSE: A side mirror of a vehicle is provided to allow a driver to recognize a vehicle or person positioned in a hidden zone by coupling a hidden zone reflection mirror to a reflection mirror attached to the side mirror. CONSTITUTION: A side mirror includes a reflection mirror(10) and a cover surrounding the reflection mirror(10) to protect the reflection mirror(10) from an external impact. The reflection mirror(10) includes a rear reflecting section(11) which is horizontally formed in line with the reflection mirror(10) and a hidden zone reflecting mirror(12) which is coupled to an end of the rear reflecting section(11) and bent at a predetermined angle so as to show the hidden zone. The hidden zone reflecting mirror(12) is integrally formed with the rear reflecting section(11). A concave mirror or a convex mirror is used for the hidden zone reflecting section of the reflection mirror.
