Abstract: Braking system includes a brake, first valve that actuates the brake based on user input, second valve configured to selectively actuate the brake, and valve actuation system including a user input device moveable between first and second positions. A brake sensor provides a signal indicative of actuation of the first valve. The valve actuation system activates the second valve if the user input device is in the first position and the first valve engaged, retaining the second valve in active state if the first valve is disengaged, deactivating the second valve if the user input device is in the second position.

Abstract: A hydraulic fan circuit is provided. The hydraulic fan circuit includes a tank, a motor having a fluid inlet and a fluid outlet and a pump to draw fluid at a low pressure from the tank and discharge the fluid at elevated pressures to the motor via the fluid inlet. The hydraulic fan circuit further includes a directional control valve disposed between the fluid outlet of the motor and the tank. The directional control valve is operable to move between a flow blocking position and a flow passing position. Further, the directional control valve is configured to reduce a positive speed of the motor below a lowest positive speed attainable through control of pump output. Furthermore, the hydraulic fan circuit includes a pressure control circuit configured to provide a pilot fluid flow at varying pressure to move the directional control valve.

Abstract: An antilock brake system for a vehicle may include a controller that is linked to a brake pedal sensor. The brake pedal sensor may be linked to a brake pedal. The brake pedal may be coupled to a normally closed brake pedal valve. The brake pedal valve may include an inlet in communication with a source of pressurized hydraulic fluid and an outlet in communication with a normally opened isolation valve. The isolation valve may be in communication with one or more main control valve systems and may be linked to a controller which maintains the isolation valve in a closed position during normal operating conditions. The isolation valve then shifts to an open position in the event current supply by the controller is interrupted as a result of an electrical failure or malfunction of the controller.

Abstract: A brake system for a mobile machine is disclosed. The brake system may have a first brake associated with a first traction device of the mobile machine, and a second brake associated with a second traction device of the mobile machine. The brake system may also have an operator input device movable through a range from a neutral position to a maximum displaced position to generate a signal indicative of a desire to brake the mobile machine, and a controller in communication with the operator input device. The controller may be configured to activate only the first brake based on the signal when the operator input device has been displaced to a position less than a threshold position within the range, and to activate both the first and second brakes based on the signal when the operator input device has been displaced to a position greater than the threshold position.

Abstract: A method of making an electrical contact comprised of at least one, and preferably several, conical projections, is provided. The individual conical projections are comprised of an ablative material, and at least some of the conical projections include a surface which is substantially comprised of material in a thickness capable of making ohmic contact, either by wiping with an intermeshing like structure or by contacting a substantially flat contact pad. An interconnection, in this invention, is the combination of at least one contact having individual conical projections and another contact, optionally having individual conical projections. The conical projections are formed by laser. The conical projections are optionally formed on the head of a contact pin.

Abstract: An electrical interconnection, which includes a method for fabricating the device, is disclosed. The interconnection comprises two contact surfaces, on at least one of which is disposed at least one conical projection in predetermined dimension and location. Rather than being permanently cojoined, the contact surfaces are attachable and detachable when desired. The individual conical projections are comprised of an ablative material, and at least some of the conical projections include a surface which is substantially comprised of material in a thickness capable of making ohmic contact, either by wiping with an intermeshing like structure or by contacting a substantially flat contact pad.

Abstract: A flexible supporting cable for an electronic device which includes a steel foil substrate, a layer of polymer on portions of the substrate, circuit pads on the polymer layer having both the bottom and top surfaces of the pads exposed; circuit lines extending from the top surface of the pads, a window free from steel beneath a portion of the circuit lines, and a second, smaller window free from both steel and the polymer beneath a portion of the circuit lines. Methods are provided for fabricating these flexible supporting cables.
