Publication number: 20180079370Abstract: A reconfigurable display system includes a camera, a thin-film-transistor layer, and a film layer. The camera is located behind a display and oriented to have a field-of-view of a viewable-side of the display. The thin-film-transistor layer of the display defines a window whereby the camera views the field-of-view through the thin-film-transistor layer. The film layer of the display defines an aperture though the film layer, wherein the film layer is positioned so that the aperture is aligned with the window. As a result, the camera views the field-of-view through the aperture and the thin-film-transistor layer.Type: ApplicationFiled: August 15, 2017Publication date: March 22, 2018Inventors: J.

Publication number: 20170061800Abstract: A one-button-security system suitable for use on an automated vehicle includes a single-action input-device, a vehicle-device, a facility-device, and a controller. The single-action input-device is operable by an operator to indicate that a vehicle is being parked. The vehicle-device is installed on the vehicle. The vehicle-device is operable to a driving-state useful when the vehicle is driven, and operable to a parked-state useful when the vehicle is parked. The facility-device is installed at a facility where the vehicle can be parked. The facility-device is operable to an away-state useful when the vehicle is not parked at the facility, and operable to a home-state useful when the vehicle is parked at the facility. The controller is in communication with the input-device, the vehicle-device, and the facility-device. The controller is configured to, in response to operation of the input-device, operate the vehicle-device to the parked-state and the facility-device to the home-state.Type: ApplicationFiled: August 24, 2015Publication date: March 2, 2017Inventor: J.

Patent number: 6850743Abstract: A tuneable radio and method for automatically adjusting the seek sensitivity alignment for seek operations. The radio has a radio receiver for receiving broadcast radio wave signals, and a tuner adjustable for selecting from a plurality of radio wave signal channels. A detector detects signal strength of the received radio wave signals, and a seek input allows a user to initiate a seek operation to select a signal channel having a signal strength exceeding a seek sensitivity threshold. A controller calculates an average signal value and adjusts the seek sensitivity threshold based on the average value. The controller adjusts the seek sensitivity when it is determined that the radio has travelled beyond a minimum distance.Type: GrantFiled: December 5, 2000Date of Patent: February 1, 2005Assignee: Delphi Technologies, Inc.Inventors: J. Roger Davis, David Arlan Copp

Publication number: 20040252191Abstract: The present invention provides an automobile entertainment apparatus display with an integrated antenna. The antenna may be integrated with the display in multiple ways, including disposing the antenna in a cavity defined by the display, mounting the antenna to the display, disposing the antenna in an aperture defined by the display, and forming the antenna on the display. The present invention also provides a display including a first planar layer adjacent a second planar layer. The first planar layer includes one or more light-emitting elements, and the first and second layers together define a cavity in which the antenna is disposed.Type: ApplicationFiled: June 13, 2003Publication date: December 16, 2004Inventors: J. Roger Davis, Ashby E. Holston, Steven C. Bower

Publication number: 20040169971Abstract: A combined audio and power connector facilitates the use of portable audio devices with audio systems, including but not limited to vehicle audio systems. By integrating an audio input and a power supply into a single connector, the need to use multiple cords, e.g., one for the power supply and another for the audio input, is avoided. Further, a vehicle can deliver power to many types of portable devices without the use of relatively large auxiliary power jacks. As a result, many or most of the auxiliary power jacks currently incorporated in vehicle designs can be eliminated, making additional space available for other applications.Type: ApplicationFiled: February 27, 2003Publication date: September 2, 2004Inventors: James J. Hinsberger, J. Roger Davis

Patent number: 6711518Abstract: A method is provided for aligning the center frequency of an infrared transmitter. The method comprises the steps of: (a) providing a voltage-controlled oscillator for driving the infrared transmitter, where the oscillator is adapted to receive a bias voltage from a microprocessor; (b) applying a bias voltage to the oscillator; (c) receiving an output signal from the infrared transmitter into an infrared receiver; (d) determining a frequency associated with the output signal; and (e) adjusting the bias voltage based on the frequency associated with the output signal, thereby aligning the center frequency of the infrared transmitter.Type: GrantFiled: August 23, 2000Date of Patent: March 23, 2004Assignee: Delphi Technologies, Inc.Inventor: J.

Patent number: 6619060Abstract: The present invention provides an HVAC fan control that includes a front fan switch, controller, rear fan switch, rear fan control circuit and a fan motor. The front fan switch and the rear fan switch electrically connect to the controller. Also, the fan motor is electrically connected to the rear fan control circuit and a front fan switch. Accordingly, the controller is responsive to inputs form the rear fan switch to operate the rear fan control circuit and select a desired fan motor speed when a logical ON condition is provided by the front fan switch.Type: GrantFiled: May 10, 2002Date of Patent: September 16, 2003Assignee: Delphi Technologies, Inc.Inventors: J.

Patent number: 6356827Abstract: A control system automatically determines the presence of an auxiliary control. The system includes a controlled device and a main control. The controlled device includes a main control input and an auxiliary control input. If an auxiliary control is present, a discernible non-zero default signal is supplied on the auxiliary control input of the controlled device, when no inputs of the auxiliary control are asserted. This advantageously allows for the verification of correct assembly (i.e., determination of the presence or non-presence of an auxiliary control) without technician intervention.Type: GrantFiled: May 30, 2000Date of Patent: March 12, 2002Assignee: Delphi Technologies, Inc.Inventors: J.
