International Classification:

F16F 904

US Classification:

267 6419, 267 6424, 267 6427, 267 6428, 280124158

Abstract:

An air spring ( ) for use in a motor vehicle suspension system is provided. The air spring includes a generally cylindrical flexible bladder ( ) having a circular upper opening ( ), a support unit ( ) sealingly connected to the flexible bladder ( ), and a unitary integrated top assembly ( ) connected to the upper opening ( ) in an air-tight manner. The support unit ( ) further includes an installation fastener ( ) for connection to vehicle support brackets ( ). The top assembly ( ) includes a sealed body ( ) having an interior open volume ( ) and optional attachment components positioned on the body to connect the top assembly to a vehicle main frame. The top assembly further includes an optional connection port ( ) adapted for pneumatic intercommunication with other air springs and an optional fill port ( ) for connection to a pressurized air system.

Appl. No.:

12/291963

Inventors:

Michael Louis David - The Woodlands TX, US
Douglas Dewayne Eggleston - Spring TX, US
Paul Freeman Noe - Sugar Land TX, US

International Classification:

E21B 7/24

US Classification:

175 57, 175107, 175320

Abstract:

Systems and methods for preventing slippage and rotation of components installed in a tubular housing member and/or along a rotatable tubular shaft during drilling operations are disclosed herein. The housing and/or rotatable shaft include a shoulder disposed proximate to one end. An adjustable member is secured proximate to the opposite end. One or more components are installed, covering a first portion of the surface between the adjustable member and shoulder. One or more spacing members are installed to cover substantially all of the remaining surface. The adjustable member is tightened such that the adjustable member and the shoulder apply a compressive axial load to the components and spacing members, causing frictional forces between adjacent objects greater than the torque acting on the housing and/or tubular shaft, causing each component to remain stationary with respect to the surface to which it is secured.

Inventors:

- Wilmington DE, US
Gerald Dale Morrison - Redmond WA, US
Michael Frederick David Olley - Scottsdale AZ, US
Daniel Keith Van Ostrand - Leander TX, US

Assignee:

SIGMASENSE, LLC. - Wilmington DE

International Classification:

G01R 31/367
G01R 31/382

Abstract:

A battery characterization system includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s) operably coupled to the DSC and the memory. Based on a reference signal, the DSC generates a charge signal, which includes an AC (alternating current) component, and provides the charge signal to a terminal of a battery via a single line and simultaneously to senses the charge signal via the single line to detect an electrical characteristic of the battery based on a response of the battery. The DSC generates a digital signal representative of the electrical characteristic of the battery. The processing module(s), based on the operational instructions, generate the reference signal to include a frequency sweep of the AC component of the charge signal (e.g., different frequencies at different times or multiple frequencies simultaneously) and processes the digital signal to characterize the battery across the different respective frequencies and generate spectrum analysis (SA) information of the battery.
