Appl. No.:

09/995105

Jeffrey T. Capek - Fishers IN
Daniel Levy - Chigwell, GB

Assignee:

BFS Diversified Products, LLC - Carmel IN

International Classification:

F16F 904

US Classification:

267 6427, 267 6419

Abstract:

An integral one-piece end plate and bracket combination is formed of a high strength plastic and is mounted in an airtight sealing engagement with an open end of a flexible elastomeric sleeve which forms the fluid pressure chamber of an air spring. The end plate includes a semi-circular wall which extends perpendicular to a longitudinal axis of the air spring and a semi-circular opening. The bracket includes an upstanding wall perpendicular to the semi-circular wall of the end plate and a half dome-shaped wall, which together with the upstanding wall, forms an auxiliary fluid chamber which is in fluid communication through the semi-circular opening with the main fluid chamber of the flexible sleeve. The upstanding wall includes attachments for securing the bracket and end plate to a support structure which aligns with a longitudinal axis of the air spring. A fluid inlet conduit extends outwardly from the upstanding bracket wall to provide fluid communication between the auxiliary fluid chamber of the bracket and an external source of pressurized fluid.

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.

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.
