  • Publication number: 20080110735
    Abstract: An electrical switch element for a relay includes a base, a compensating element, and an actuating device. The base is provided with fixed contacts. The compensating element includes first and second switch contact carriers provided with switch contacts that correspond to the fixed contacts. The first and second switch contact carriers are connected by a rigid body joint arranged there between such that the first and second switch contact carriers are pivotable about a pivot axis. The rigid body joint has a support surface. The actuating device is in contact with the support surface. The actuating device applies a switching force to the support service to cause the first and second switch contact carriers to pivot about the pivot axis to move the switch contacts into or out of electrical contact with the fixed contacts.

  • Publication number: 20070131347
    Abstract: A method of forming a fabric covered article includes providing a substrate and trim cover laminate. The trim cover laminate includes a trim cover portion and a heat-activated adhesive portion laminated to a B-side surface of the trim cover portion, the adhesive portion defining an exposed surface. The exposed surface of the adhesive portion is exposed to heat, thereby activating the adhesive portion. The substrate is positioned onto the activated adhesive portion of the trim cover laminate to bring the substrate and the trim cover portion into contact with one another, thereby forming a fabric covered article.

  • Patent number: 7135946
    Abstract: A double relay is described which has two relay actuators which are inserted into a common receptacle. Each relay actuator has a first fixed contact and a movable contact. Arranged on the receptacle are two second fixed contacts, in each case a second fixed contact being associated with a movable contact of a relay actuator. The receptacle has a plurality of connection pins by way of which an electrical contact may be made with the relay actuators and the second fixed contacts. The double relay can be manufactured at low cost.

  • Patent number: 7072765
    Abstract: A method for calculating a route from a starting location to a destination location is described; it is characterized in that the route is calculated after specifying at least one pass-through destination location by way of at least one pass-through destination point, which is situated in a circumscribed area of the at least one pass-through destination location specified by a specified criterion. In contrast with the route calculation method known from the related art, the specified pass-through destinations are not part of the trip route, but instead, except for a specified circumscribed area, they function as vaguely specified interpolation points for influencing the route calculation.

  • Publication number: 20060139133
    Abstract: A relay has a magnet system with a core partially enclosed by a coil. A yoke has a first yoke leg attached to a first end of the core and a second yoke leg extending parallel to the core. The second yoke leg has an armature mounting portion formed on an upper side of the second yoke leg remote from the coil. A pole has a first pole leg connected to a second end of the core and a second pole leg extending parallel to the core. The second pole leg has an upper surface substantially aligned with the armature mounting portion. A fixed contact is arranged on a fixed contact carrier substantially aligned with the second pole leg. The arrangement of the magnet system ensures precise positional alignment during extrusion coating with a plastic material.

  • Patent number: 7053738
    Abstract: A relay and a process for producing a relay are described, three contact pins being provided for the relay. The three contact pins are preferably manufactured from a stamping and are fixed together as a contact stamping with respect to a yoke through insertion into a base. As a result of the use of a contact stamping with the three contact pins connected rigidly to one another, adjustment and handling of the three contact pins during production of the relay is relatively simple.

  • Patent number: 6996469
    Abstract: A method of route calculation in an vehicle navigation device is described, whereby a route from a starting location or a current location to a destination location is calculated, so that in the case of a deficiency in the vehicle or a deficiency impairing the driver of the vehicle, the route to an alternate destination location which has facilities for eliminating the deficiency is calculated instead of the original destination location. In addition, a method of navigation of a driver of a vehicle from a starting location to at least one destination location is also described, a trip route from the starting location or a current location to the at least one destination location being determined, and driving instructions being generated as a function of a current location so that in the case of a deficiency in the vehicle or a deficiency impairing the driver of the vehicle, the trip route to an alternate destination location which has the facilities for eliminating the deficiency is calculated.

  • Publication number: 20060009052
    Abstract: A coil housing for a relay and a method of making the same, the coil housing comprises a first housing member and a second housing member. The first housing member includes a first flange with a first tubular half extending therefrom. The second housing includes a second flange with a second tubular half extending therefrom. The second tubular half engages with the first tubular half to form a coil receiving tube connecting the first and second housing members. Connectors formed of a punched sheet metal are molded in at least one of the first and second housing members.

  • Patent number: 6849684
    Abstract: The invention provides a molded composition having improved noise damping properties, made of a blend of a soft thermoplastic polyether elastomer and a hard polyester resin reinforced with a fibrous or particulate filler, the molded composition having an inhomogeneous structure comprising a surface part which is rich in elastomer and depleted in the polyester resin and the reinforcing filler compared to its inner part, obtained by monocomponent injection molding of a blend of the soft and the hard polyester resin wherein only the polyester resin contains the reinforcing particulate filler. The molded composition has a flex modulus Fm in the range 0.5 to 10 GPa, and maintains a sufficient minimum tan delta damping factor t_ over a temperature range of ?50° C. to 170° C.

  • Patent number: 6714862
    Abstract: A navigational method and a navigational system for determining a route from a starting location to a destination location for a means of locomotion, especially for a motor vehicle, an airplane, or a ship, the route being calculated on the basis of a digital database, which contains predetermined path segments Wi having correspondingly assigned nodal points Ni, which connect the specific path segments Wi to each other, the specific weightings Gi being assigned to the path segments Wi and/or to the nodal points Ni. In this context, the weightings Gi that are used for the route calculation are varied as a function of the time of day.

  • Patent number: 6711498
    Abstract: A method for operating a navigation system for a vehicle, particularly for a motor vehicle, in which a travel route is calculated in a computing circuit on the basis of a location of the vehicle, a digitally stored map and a destination location, and is made available to the vehicle driver as an acoustical and/or visual message, where traffic information relevant to the travel route may be acquired via a receiver unit and a new travel time t resulting therefrom is calculated for the existing travel route with the aid of a predefined weighting factor Gf for a disturbance event and the length of a traffic disturbance Ls, and a travel time ta is calculated in the same manner for an alternative route, and in the event that the travel time ta of the alternative route is shorter than the travel time t of the travel route, is indicated to the vehicle driver.
