US Patent:

6881016, Apr 19, 2005

Filed:

Mar 24, 2003

Appl. No.:

10/395625

Inventors:

James L. May - Independence MO, US

International Classification:

B23G011/00

US Classification:

408 67, 408204

Abstract:

A core retainer includes a base plate releasably attached to a concrete floor from which a concrete core is to be removed. A brake assembly atop the plate includes a plurality of brake pads for contact with the interior of the core drill bit. The retainer is configured to fit within the core drill bit and either rotate with the core drill bit or be stationary relative thereto. Upon drilling, the plate and separated core fall to the floor below. This movement is translated to the brake assembly by the linkage such that the brake pads engage the core drill bit at a sufficient pressure allowing for the separated core to be retained within the core drill bit.

Appl. No.:

6/135601

Inventors:

James I. May - Royal Oak MI

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

F16H 104

US Classification:

74422

Abstract:

A rack and pinion gear set wherein a driving pinion having spur gear or helical gear teeth rotates to produce axial displacement of the rack member has a saddle bearing located above the pinion for supporting the rack shaft. The saddle bearing furnishes support surfaces, which engage complementary support surfaces on the rack shaft. The surfaces have a center of curvature located at approximately the center of the contact area on the face of the pinion teeth. A second embodiment has a cradle bearing for supporting the rack shaft on planar surfaces and has, at its outer periphery, a cylindrical surface which is held by a saddle bearing. The center of curvature of the cylindrical surface is likewise located approximately at the mean contact surface on the pinion teeth faces.

David TRUMPY - Novi MI, US

International Classification:

G10K 11/178

Abstract:

An active noise cancellation (ANC) system may include an adaptive filter divergence detector for detecting divergence of the one or more controllable filters as they adapt, based on dynamically adapted thresholds. Upon detection of a controllable filter divergence, the ANC system may be deactivated, or certain speakers may be muted. Alternatively, the ANC system may modify the diverged controllable filters to restore proper operation of the noise cancelling system.

Appl. No.:

15/911553

Inventors:

- Stamford CT, US
James MAY - Milford MI, US

International Classification:

B60C 23/06
G10K 11/178

Abstract:

A sensor is configured to infer a rotational speed of a tire of a vehicle. A frequency generator is configured to synthesize frequencies of a tire cavity resonance according to the rotational speed of the tire to generate a sense signal. An active noise control filter is configured to generate an antinoise signal from the sense signal. A loudspeaker configured to convert the antinoise signal into antinoise and to radiate the antinoise to a listening position. The antinoise signal is configured so that the antinoise reduces sound of the tire cavity resonance at the listening position.

Inventors:

- Detroit MI, US
Scott M. Reilly - Southfield MI, US
James May - Milford MI, US

Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS LLC - Detroit MI

International Classification:

H04R 3/00

Abstract:

A vehicle system is provided that includes a sound augmentation system with a sound augmentation generator that produces an augmented audio output to drive at least one audio output based on a transfer function. The vehicle system also includes a sound augmentation system health monitor that determines a current performance level of the sound augmentation system based on at least one audio input and a feedback of the augmented audio output, and triggers a transfer function update prompt based on a difference between the current performance level and an expected performance level being at a threshold level. A user interface outputs the transfer function update prompt and receives a transfer function calibration request in response to the transfer function update prompt. A transfer function calibration module drives a calibration sequence on at least one audio output and monitors at least one audio input to determine an updated transfer function.

Appl. No.:

13/768249

Inventors:

Dennis Klug - West Bloomfield MI, US
James May - Milford MI, US
Davis Pan - Arlington MA, US

International Classification:

G10K 11/16

US Classification:

381 714

Abstract:

Systems and methods to cancel noise in a vehicle are disclosed. A first speaker is positioned forward of a steering wheel of a vehicle. The first speaker generates a first signal configured to acoustically cancel noise produced by operation of the vehicle. A second speaker is positioned forward of the steering wheel. The second speaker generates a second signal to acoustically cancel the noise produced by the operation of the vehicle. The first and the second speakers are capable of generating the first and the second signals independently of one another.
