A plurality of terminals are mounted on the circuit board so as to be in electrical communication with electrically conductive members. The terminals have contact portions disposed below the circuit board in the lower terminal receiving cavities. The terminals extend from the circuit board by a first predetermined distance. Alignment posts are fixed to the circuit board and received within the alignment cavities. The alignment posts extend from the circuit board by at least a second predetermined distance which is greater than the first predetermined distance.

PROBLEM TO BE SOLVED: To provide a system for controlling an electric motor which allows for operation of a battery in reverse polarity state.SOLUTION: A control system 100 comprises: a power supply 114; a switching element 116 connected in series with an electric motor 112 and switching it between "on" state and "off" state; a control element 118 for controlling the switching element 116; and a thyristor 124 connected in parallel with the electric motor 112. Conduction state or non-conduction state of the thyristor 124 is controlled by the control element 118. A control method includes a step 212 for switching the state of the thyristor 124 by the positive polarity state of a battery so that the thyristor 124 conducts a current, and switching the state of the thyristor 124 by the reverse polarity state of a battery so that the thyristor 124 does not conduct a current.

PROBLEM TO BE SOLVED: To provide a grommet (22) being inserted into the hole (44) of a panel (24) extending along the axis (A).SOLUTION: A grommet (22) includes a hollow funnel-like section (32) inclining for the axis (A) so that a portion of which is compressed radially inward during insertion into a hole (44), and terminating at a circular projection line (40). The grommet (22) further includes a holding groove (48) adjacent to the projection line (40), and receiving a panel (24) when the grommet (22) is inserted completely into the hole (44). A series of recesses (62) are provided in the inner side face (56) of the grommet (22). These recesses (62) are configured to expand when the funnel-like section (32) passes through the hole (44) during insertion of the grommet (22) into the hole (44).

PROBLEM TO BE SOLVED: To discourage animals and foreign objects from coming to rest and overlie a ground-based transducer.SOLUTION: The transducer includes a housing having a domic shape. The transducer is associated with a vehicular electrical charging system (ECS) used to electrically charge an energy storage device (ESD) disposed on a vehicle. The transducer is adapted for attachment to a ground surface with the domic-shaped housing extending outwardly away therefrom. The domic-shaped housing of the transducer, when disposed beneath an undercarriage of a vehicle, fills a space intermediate the transducer and the undercarriage such that animals, such as a dog or a cat, are discouraged from overlyingly residing thereon. External surface segments of the domic-shaped housing depend or slope away from a peak point of the domic-shaped housing so that foreign objects, like a soda can or a tool that engage the domic-shaped housing, may passively slidingly move off of the housing to ensure optimal performance of the transducer.

PROBLEM TO BE SOLVED: To provide a method and apparatus for identifying a gas sensor fault.SOLUTION: A method for fault identification of gas sensors exposed to a gas mixture is disclosed for gas sensors having an output that depends on concentrations of two gas species in the gas mixture. The method includes receiving output signals from two such sensors, processing the output signals in a controller that implements a model of the sensors so as to identify a fault in the first gas sensor or the second gas sensor; and providing an indication of any identified faults.
Abstract:
PROBLEM TO BE SOLVED: To provide methods of forming a sealed crimp connection for attaching a terminal to a wire conductor.SOLUTION: A layer of fluid conformal coating is applied so that it overlies a terminal and underlies at least a lead of the wire conductor when at least the lead is received into the terminal. The terminal, the fluid layer, and at least the lead of the wire conductor are crimped to form a crimp connection. Fluid conformal coating is placed at a position where an abutting surface of the terminal makes contact with at least the lead of the wire conductor. The fluid conformal coating is cured to a non-fluid state. The fluid conformal coating may be formed of an acrylated urethane material that may provide an increased pull force and a low crimp resistance in the crimp connection. The crimp connection may be constructed using a manufacturing process on an automated assembly line.
Abstract:
PROBLEM TO BE SOLVED: To provide power charging assembly and methods to provide a pre-charge low-current state, a steady-state, high-current charging state, and an unconnect state for an electrical load of an electrical propulsion system in a hybrid electrical vehicle (HEV).SOLUTION: The power charging assembly includes a positive contactor device, a negative contactor device, and a non-contactor device means. The rate at which that electrical load is pre-charged may be effectively controlled by using a pulse-width modulated (PWM) signal received by the non-contactor device means. A current-only carrying positive or negative contactor may be configured with the non-contactor device means to further prevent electrical arcing of the contacts of the positive and the negative contactor during power charging assembly operation.

PROBLEM TO BE SOLVED: To provide a connection part with improved corrosion-resistance between a cable and a terminal to be connected to this. SOLUTION: This is a method of forming a seal between a terminal 22 and a cable 10 having an insulating outer cover 12 and a core 14 which is conductive and is electrically in contact with the terminal, and the method comprises a process to provide a lead wire 16 of the core extending over an edge part 43 in an axial direction of the insulating outer cover, a process of spraying a conformable coating 20 on the lead wire, a process in which, when the conformable coating is still in wet condition, the terminal is crimped to the cable, and the conformable coating is displaced from between the lead wire and the contact face of the terminal, and the remaining portion of the lead wire not in direct contact with the terminal is covered and sealed with the conformable coating, and a process in which the conformable coating is hardened on the remaining portion of the lead wire.
