Filed:

Jul 22, 2004

Appl. No.:

10/898422

Inventors:

Keith Andreasen - Huntington Beach CA, US
David Rich - Huntington Beach CA, US

International Classification:

B60Q 1/00
G06F 19/00

US Classification:

340438, 340459, 340461, 701 29, 701 33, 701 24

Abstract:

An instrument is provided which is in electronic communication with an on board diagnostic system (OBD) of an automobile. The instrument selectively queries the OBD with batch requests for the purpose of reducing a processing load placed on the OBD PCM. The instrument obtains numerous operating conditions through the OBD, and displays the operating conditions in an intuitive format. The operating conditions may be grouped into five different modes, and the five most relevant operating conditions within each mode may be displayed on the monitor either by default or through customization by the user.

US Classification:

701 35, 701 29, 701 33

Abstract:

A scan tool is provided which comprises a housing which houses a display and six mode buttons. The scan tool is communicable with an OBD of an automobile and provides information retrieved therefrom to a user of the scan tool in an efficient and effective manner. In particular, the display displays a plurality of information on one screen. For example, the display may display information related to I/M Monitor Status simultaneously with MIL status, stored, pending or historical codes. Further, the scan tool allows the user to switch between modes by depressing the mode button of the desired mode without having to manually exit the current mode and manually enter the desired mode.

Appl. No.:

7/778501

Inventors:

David A. Rich - Woodmere NY

International Classification:

H04B 110

US Classification:

455306

Abstract:

An improved adaptive notch filter for removing undesired cochannel FM interference includes in-phase and quadrature signal processing paths in which the undesired FM signal is translated to zero frequency, i. e. to DC. In each of the in-phase and quadrature phase signal paths, a first multiplier translates the input frequency spectrum in a dynamic manner so that the frequency of the undesired FM signal is always centered on DC. The undesired signal, now at DC, is filtered out by a high pass filter with a sharp rolloff. The output of the high pass filter is remultiplied in a second multiplier to translate the desired FM signal back to the original position in the frequency spectrum. In order to eliminate an unwanted difference frequency remodulation signal at the output of the second multiplier, the quadrature phase signal path performs a parallel operation on the same input signal, but with a quadrature phase (90 degree phase shift) control signal. The output the in-phase and quadrature signal processing circuits are combined in an adder circuit to cancel the unwanted difference frequency remodulation signal.

International Classification:

H03M 302

US Classification:

341143

Abstract:

A feedback coder, which employs simple CMOS push/pull amplifiers as gain elements, along with a bistable circuit, in its preferred embodiment takes the form of a second-order delta-sigma modulator. The output of the modulator is converted into pulse code modulated words by a finite impluse response filter which incorporates a partial coefficient generator utilizing simplified logic. The generator output is provided to an accumulator in which the stage operate at reduced speed. A simple multiplexer generates a serial output. The entire converter can be integrated on a semiconductor chip of relatively small area.
