Filed: 1994-04-20
Abstract: PURPOSE:To provide a warning device for the distance between vehicles preventing erroneous warning due to a guard rail along curved road and on interrupting vehicle. CONSTITUTION:A guard rail along a curved road is judged to be an object which changes from a stopped object to a moving one (travelling vehicle). If it is treated as a moving object just after the change, an erroneous warning can be issued by a slight approach to the guard rail. In the case of interruption of a large vehicle, the side is detected and erroneous warning can be issued changing from an unidentified object to the moving one. But, by the processing of the steps 444 and 446, in a prescribed waiting time, it is judged to be a guard rail or an interrupting vehicle and no warning processing is performed. When it is really 9 curve of guard rail or an interrupting vehicle, the normal recognition is get back during the waiting time and the erroneous warning can be prevented.

Title: Backup circuit
Inventor: OKABE TAKAYUKI
IPC: G06F1/26
Filed: 1995-03-15
Abstract: PURPOSE: To prevent excessive discharge by opening a relay contact between a chargeable battery and a load circuit when no backup is required for performing trickle charging and closing the relay contact by discharging a capacitor only while the backup of the battery is required. CONSTITUTION: A contact (r) of a relay R is inserted between a load circuit 1 and a chargeable battery 2. An electric charge is charged to a capacitor 3 while an external power supply V is normal and a drive current is supplied to the relay R when the external source V goes down for closing the contact (r) and supplying current to the load circuit 1 from the chargeable battery 2. When the external power supply V is normal, power is fed to a DC/DC converter 5 via a diode 4. The battery 2 results in a trickle charging state of approximately 3mA with a diode 6 and a resistor 7. When the external power supply V is turned off, the contact (r) closes and power is supplied to the DC/DC converter from the battery 2 via a diode 9 until the charge of the capacitor 3 disappears, thus easily adjusting backup time and preventing over-discharging.
