20. The device according to claim 19, further comprising an engagement member for operatively connecting said damper member with said actuating device, whereby said damper is controlled by operation of said actuating device.
21. A method for converting an air port cleaner device having an extensible sleeve cleaning member, comprising the steps of:
removing the sleeve cleaning member; and
installing a cleaning member that presents a larger overall cleaning area on an insertion stroke and a smaller overall area on a withdrawal stroke in place thereof.
22. The method according to claim 21, further comprising the step of installing an air port casting on the air port.
23. The method according to claim 21, further comprising the step of installing an air port damper mechanism.
24. The method according to claim 23, wherein said step of installing an air port damper mechanism comprises installing the damper mechanism such that a first portion of an extension stroke of a cleaning actuator is adapted to control the extent to which the damper mechanism covers the air port.
25. The method according to claim 24, wherein said damper mechanism is operatively engaged with said actuator via a cam follower mechanism.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A parking status control system comprising:
a parking space sized and constructed for parking a vehicle, the parking space including an entry side, a stop side, a left side and a right side;
a vehicle presence detector for detecting the presence of a vehicle;
a parking stop for obstructing the movement of the vehicle, said parking stop located at said stop side of said parking space; and
a video recorder located within said parking stop, said video recorder positioned for recording video images of vehicles parking in said parking space.
2. The parking status control system of claim 1 further comprising:
a transmitter for transmitting video images of vehicles to parking enforcement personnel.
3. The parking status control system of claim 1 further comprising:
a processor connected to said vehicle presence detector for processing predetermined variables to determine whether a vehicle parked within said parking space is parked without authorization; and
a transmitter for transmitting video images of vehicles to parking enforcement personnel, said transmitter transmitting said video images upon determination by said processor that a vehicle parked within said parking space is parked without authorization.
4. The parking status control system of claim 3 wherein said processor and transmitter are located within said parking stop.
