Filed:

Mar 27, 2003

Appl. No.:

10/397289

Inventors:

William Welch - Mountain View CA, US

Assignee:

Snap-On Incorporated - Pleasant Prairie WI

International Classification:

G06F019/00

US Classification:

701111, 701114, 324379, 73116

Abstract:

Methods and devices for measuring and calculating various kinds of parameters of a running engine are disclosed. A camera may be positioned to capture a plurality of images of a moving component that is being driven by the an engine. From the plurality of images, a velocity of the moving component may be measured, and an acceleration then derived. From the derived acceleration, various parameters of the running engine may be calculated, including but not limited to, number of firing cylinders, rotational rate, and relative cylinder balance. These and other parameters may then be reported, such as through a display screen, to a user. The methods and devices disclosed herein may also generate recommendations for specific kinds of maintenance to an engine based on the results of parameter measurements and calculations, then report those recommendations to a user.

International Classification:

G01M 17/00
G06F 7/00
G06F 11/00

US Classification:

701 29, 701 34, 714100

Abstract:

Measurement data storage is triggered in response to occurrence of a user set condition with respect to one or more user-selected measured parameters, to thereby capture real-time monitored test data. In an application for a vehicle diagnostic tool, such as an engine analyzer, the measurements and attendant display may be provided during engine operation or actual vehicle operation. The tool software allows a user to specify any one or more of the measured parameters; and for any selected parameter, the user can identify an event with regard to the selected parameter. During the test, the processor executing the software captures measured parameter data, and the processor analyses the appropriate measured parameter data with respect to any and/or all user specified conditions. Triggering may be based on occurrence of an event or combinations of events. When triggered, the software will cause the tool to store some amount of captured data and/or pause the display to allow the user to analyze all available data.

Appl. No.:

11/472800

Inventors:

William J. Welch - Berkeley CA, US

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

H01Q 13/00
H01Q 15/14

US Classification:

343781CA, 343781 P, 343912

Abstract:

The present invention relates generally to the field of reflector-type antennas based on the offset Gregorian design having a substantially paraboloidal-shaped primary reflector and a substantially ellipsoidal secondary reflector displaced from the optical axis of the primary reflector. The first focus of the secondary reflector is substantially coincident with the focus of the primary reflector and a feed or detector is placed substantially at the second focus of the secondary reflector. A partially open shroud placed between the primary reflector and the secondary reflector is shown to result in reduced ground interference and improved antenna efficiency and sensitivity.

Appl. No.:

13/622114

Inventors:

William Welch - Los Altos CA, US

Assignee:

Uncommon LLC - Chicago IL

International Classification:

B65D 25/24

US Classification:

206 452, 206320

Abstract:

A cover for an electronic device having a first panel including a first and second edge, a second panel including a first and second edge and being positioned adjacent the first panel, a third panel including a first edge adjacent the second panel opposite the first panel, and means for connecting the first panel to a device holder or to the device itself. The cover may attach to a separate back panel which can be detachably secured to the electronic device. The second edge of the first panel, the first and second edges of the second panel and the first edge of the third panel are slanted so as to allow adjacent panels to be configured to form an angle to one another. The edges of adjacent panels are V-shaped and include two sidewalls which abut when the panels move together. This limits the minimum angle between adjacent panels.

International Classification:

C07C 4118

US Classification:

568626

Abstract:

Disclosed is a method for the preparation of 8-methoxy-4,8-dimethyl-1-(4-isopropylphenyl)-nonane which comprises the steps of (a) reacting para-isopropylbenzyl chloride with triphenylphosphine in the presence of a suitable solvent for a sufficient period of time and at a sufficient temperature to form an intermediate product in solution, para-isopropylbenzyl triphenylphosphonium chloride, and (b) reacting said solution with sodium methoxide, followed by methoxycitronellal to produce cis- and trans-8-methoxy-4,8-dimethyl-1-(4-isopropylphenyl)-1-nonene, (c) separating said intermediate product from the residual reactants, and (d) hydrogenating said cis- and trans-8-methoxy-4,8-1-(4-isopropylphenyl)-1-nonene, in the presence of a suitable solvent and catalyst to form 8-methoxy-4,8-dimethyl-1-(4-isopropylphenyl)-nonane.
