The end cap includes a gutter trough closure region, for blocking water flow from the end of the gutter, and a second, above-trough closure region for blocking entry of leaves and other debris into the end of the gutter between the gutter trough and the overlying cover.

Abstract: A method of controlling vehicles parked in a parking system. A user sends a user-specific code to a parking system computer via a mobile telephone system when beginning and terminating a parking period. The identity of the parking zone concerned is sent to the computer, in which a vehicle-specific code is stored and is tied to the user-specific code. A parking attendant uses a control unit for wirelessly fetching information concerning vehicles that have commenced but not terminated a parking period in the zone concerned. The control unit sends to a telephone coupled to the computer a voice message from the parking attendant that includes a vehicle registration number. The computer compares that registration number with the registration numbers of logged-in vehicles and sends to the control unit a voice message repeating the registration number and including information as to whether the vehicle is logged-in.

The intermediate shaft is operatively coupled with the output shaft through a first clutch and the input shaft of the variable speed drive unit is operatively coupled with the output shaft through a second clutch.

Abstract: A power transmission for a motor vehicle. The transmission includes a plurality of transmission ratio steps defined by pairs of gear carried on parallel shafts, and final output mechanisms for engaging desired transmission ratio steps. The final output mechanisms are operable for controlling the engagement of respective transmission ratio steps to minimize tractive force interruption by allowing rapid gear changes to be effected to reduce the times between shifts of gears. By sensing accelerator pedal position and vehicle speed a new transmission ratio step to be subsequently engaged can be pre-selected while an engaged gear remains engaged.

Abstract: A transmission system including a shift mechanism for operating and controlling the transmission system. To automatically detect geometric characteristic values of the transmission system or of the shifting device a selector motor and a shift motor actuate a selector finger that is displaceably mounted in a selection-shift-passageway layout. Starting from an initial position whose coordinates within the selection-shift-passageway layout are unknown, the selector finger is displaced in the directions of shifting and in the directions of selection in order to detect paths of movement in the direction of selection or shifting. The selector finger is repeatedly displaced to establish the maximum paths of movement until the predetermined transmission geometric characteristic values are completely detected. Also disclosed are a control device for controlling a transmission system that includes a shift mechanism, and a method for controlling such a transmission system.
