US Patent:

60170972, Jan 25, 2000

Filed:

Dec 29, 1997

Appl. No.:

8/999048

Inventors:

Robert Spence Weir - American Canyon CA

International Classification:

B60B 2700

US Classification:

3011051

Abstract:

A wheel hub assembly that has a hub retained within a rotatable inner race of a bearing. The bearing is non-rotatably mounted by a portion of it's outer race within the bore of a bearing housing. This bearing housing has threaded holes on a diameter within its' face to accept bolts by attachment to an axle housing end support. Non-rotatably mounted within the bearing housing is a lip seal to prevent contaminants from entering the bearing. On the face of the hub is a groove on a diameter for accepting an o-ring sealing member to furnish a barrier between the face of the hub and the drive axle preventing loss of differential lubrication. Bolts are threaded through the hub on a diameter within its face for securing a wheel and engaging a drive axle, whereby the support of the wheel is not dependent upon the drive axle.

Abstract:

Device and method for accurately recreating verification markings with removable ink on progressive ophthalmic lenses and molds are provided. The device includes (a) a stage which defines a coordinate system and which is adapted for receiving a lens or mold; (b) a magnifying device for locating the reference marks on the lens or mold surface; (c) a computer for storing coordinates from the platform wherein the coordinates represent the locations of two reference marks on the lens or mold surface; and (d) a pen device adapted to be positioned over the surface of the lens or mold wherein the pen device is controlled by the computer for applying the verification markings on the lens or mold surface.

Abstract:

A speaker simulator receives a high power musical signal from a power amplifier, and a reduced power signal is extracted by a pad circuit and directed to a high-pass filter and a fan circuit which drives a cooling fan. The output of the high-pass filter is directed to a servo amplifier and a series of notch filters, prior to output from the speaker simulator. The angular momentum of the blades of the cooling fan provides an history-dependent impedance, i. e. , an impedance dependent on the past values of the signal driving the fan. The history-dependent impedance produces an aesthetically pleasing distortion of the speaker simulator output.
