摘要:
A communication signal suppressing apparatus capable of reducing a load of a firmware using portion is provided in a communication signal apparatus such as a common line signal apparatus. A common line signal processing circuit corresponds to hardware used to execute a portion of the level-2 process operation, and this common line signal processing circuit owns such a function capable of discarding a reception frame having no meaning other than a confirmation response, and also capable of extracting a reverse-direction sequence number thereof. As a result, the common line signal processing circuit performs a remaining level-2 process operation. Thus, since a workload of a processing apparatus (CPU) using the firmware can be reduced, this firmware can be designed with sufficient capacities. Also, other process operations can be carried out by this CPU.

A trunk locked-in person saving apparatus without using a mechanical lever. The trunk locked-in person saving apparatus includes: a pyroelectric sensor for detecting behavior of a person who is accidentally locked in a trunk; a detection apparatus for detecting a fact that a person is locked in the trunk based on a detection signal from the pyroelectric sensor; and a trunk opener for releasing a latch condition of the trunk. When the detection apparatus detects that a person is locked in the trunk, the detection apparatus controls the trunk opener to release the latch condition of the trunk.
