US Patent:

20130009465, Jan 10, 2013

Filed:

Mar 25, 2010

Appl. No.:

13/636930

Inventors:

Pranay Kumar Bajjuri - Allen TX, US
John Jacob - Fort Wayne IN, US

Assignee:

International Truck Intellectual Property Company, LLC - Lisle IL

International Classification:

B60L 1/00

US Classification:

307 91

Abstract:

The loads of a vehicle electrical system are connected to a power distribution bus through a first or through first and second latching relays. A set of vehicle mandatory loads are connected to an output side of the first latching relay to be cut off from the power distribution bus upon opening of the first latching relay. A set of vehicle optional loads are connected to an output side of the second latching relay to be cut off from the power distribution bus upon opening of the first latching relay or the second latching relay. Opening and closing of the first and second latching relays depends of the values for the measured current and measured voltage. Among factors relating to opening and closing of the first and second latching relays are measured voltage exceeding a voltage high threshold, in which case the first latching relay opens, measured voltage falling below a low voltage threshold in which case the second latching relay opens while the first latching relay remains closed and a positive current transient exceeding a minimum threshold, which opens the first latching relay.

International Classification:

B60L 11/18
H02J 7/00

US Classification:

320104, 320109

Abstract:

A vehicle electrical power system includes a generator which generates power for application to loads and to chassis and batteries for storage. A starter motor for an engine is energized primarily from the battery. A contactor between the batteries has a closed state in which power can flow between the batteries and an open state which interrupts power flow between the batteries and from the generator to the cranking battery. A controller enables periodic stopping and starting of the engine is responsive to a battery state of charge for at least one of the batteries for operating the engine to maintain a minimum battery state of charge. The contactor may have a limited closed state in which power flow between the batteries is surge limited. Power flow is surge limited through the connector responsive to a voltage difference between the batteries.

Assignee:

International Truck Intellectual Property Company, LLC - Warrenville IL

International Classification:

B60Q 1/56
B60Q 1/26

US Classification:

362497, 362487

Abstract:

A lighting assembly has a first array of lamp elements to a first side of a central zone and a second array of lamp elements to a second side of the central zone. Each array has at least one low intensity lamp element operable to cause the lighting assembly to present a low intensity brightness to an observer viewing the lighting assembly and at least one high intensity lamp element operable to cause the lighting assembly to present a high intensity brightness to an observer viewing the lighting assembly, and an electrical connector through which electric current is fed to operate the lamp elements.

International Classification:

A01C 7/20
A01C 7/08

Abstract:

A row unit for a seeding machine includes a frame supporting a gauge wheel and a seed meter. A depth stop assembly includes a stop setting an upward travel limit of the gauge wheel with respect to the frame, and a handle that is lockable and releasable to move the stop to select among seeding depths. A downforce actuator is operable to generate downforce to be applied through a gauge wheel arm and the gauge wheel to the soil. A downforce sensor is incorporated into the depth stop assembly and movable therewith. The depth stop assembly includes a multi-piece body having a first piece receiving the handle, and a second piece defining a pivot. The first piece of the multi-piece body includes a handle-receiving receptacle portion, a fastening portion for fastening to the second body piece adjacent the pivot, and a portion therebetween forming a housing of the downforce sensor.

Abstract:

A towed agricultural machine includes a converter, configured to convert a first voltage potential generated by a generator to a second voltage potential. The second voltage potential powers a component of the towed agricultural machine. Further, the towed agricultural machine also includes a switch that senses the absence of the second voltage potential from the converter and switches to powering the subcomponent with a second voltage potential received from a source external to the towed agricultural machine.
