7652583, Jan 26, 2010

Filed:

Mar 20, 2007

Appl. No.:

11/688375

Inventors:

Julian Sanchez - Bettendorf IA, US
Jerry Richard Duncan - Bettendorf IA, US

Assignee:

Deere & Company - Moline IL

International Classification:

G08B 23/00

US Classification:

340575, 340576

Abstract:

A method and system for maintaining operator alertness comprises a detector for detecting a physical status of an operator. The physical status indicates a first level of operator alertness. A user interface requests a second level of operator alertness from a self-evaluation of the operator at a request time. An evaluator measures at least one of an accuracy of the operator response to the requested input and a response time of the operator from the request time. An alert module generates alarm data or an alarm signal to alert the operator based on the first level of operator alertness indicating an inattentive state and at least one of the measured accuracy and operator response time indicating the inattentive state.

International Classification:

G08B 23/00

US Classification:

340575, 340576, 348143, 382117, 382118

Abstract:

A method and system for detecting operator alertness of an operator of a vehicle or machine comprises an image collection system. The image collection system collects reference motion data associated with an operator representation when the operator is in an alert state. An image processor determines observed motion data of one or more points of a three dimensional representation of the operator during a time interval. An analyzer sends an alert signal to alert the operator if a detected angular shift of one or more points of the representation exceed a displacement threshold.

US Classification:

340575, 340576, 348143, 382117, 382118

Abstract:

A method and system for detecting operator alertness of an operator of a vehicle or machine comprises an image collection system. The image collection system collects reference position data and reference motion data associated with an operator, or a portion thereof, when the operator is in an alert state. An image, processor determines observed position data and observed motion data of one or more points of a three dimensional representation of the operator during a time interval. An analyzer sends an alert signal to alert the operator if a detected angular shift of one or more reference points of the representation exceeds at feast one of a displacement threshold and a motion threshold.

International Classification:

G08B 23/00

US Classification:

340575, 340576, 348143, 382117, 382118

Abstract:

A method and system for detecting operator alertness of an operator of a vehicle or machine comprises an image processor and an analyzer. The image processor determines whether at least one eye of an operator is visible and determines whether the operator is generally facing forward with respect to the vehicle. The analyzer applies at least one of position analysis and motion analysis to a three dimensional representation of an operator to determine alertness of the operator if at least one eye of operator is not visible or If the operator is generally facing forward.

US Classification:

180336, 180321, 180329, 180333, 180334, 180402

Abstract:

A creep steering control system for a utility vehicle is operable from a rearward-facing position. The creep steering control system includes a pivotable actuator alongside a rearward-facing seat that provides electronic output based on the position of the actuator. A linkage is provided between the pivotable actuator and steering wheel behind the seat.

Assignee:

Deere & Company - Moline IL

International Classification:

G06T 11/20

US Classification:

345440

Abstract:

A method and system for displaying information related to a work vehicle comprises sensors for detecting levels associated with corresponding performance variables. An assignor assigns points in an image or graphical data representation associated with corresponding detected levels. A graphical module interconnects the points in the image to form a performance polygon indicative of a collective level of performance of the performance variables. A display is arranged for displaying the performance polygon to a user.

Abstract:

The different illustrative embodiments provide a method, apparatus, and computer program product for generating alerts. Responsive to an occurrence of an event, a current gaze zone in a plurality of gaze zones associated with a current view of an operator is identified. A desired gaze zone in the plurality of gaze zones is identified for the event. The desired gaze zone contains a source location for the event. A determination is made whether the current gaze zone is inside the desired gaze zone. Responsive to a determination that the current gaze zone is outside the desired gaze zone, an alert is generated.
