International Classification:

G06F 1100

US Classification:

714 48, 714 43, 716 4

Abstract:

In an embodiment, a bus controller for connecting a device to an Inter-Integrated Circuit (I2C) bus includes fault tolerance features. The I2C bus controller may support fail silent, cyclic redundancy check (CRC), and byte count check operations. The I2C bus controller may include a control unit connected to an I2C core module having a base address. The I2C bus controller may also include a second I2C core module having a base address plus one (BP ). The I2C bus controller may also include a mute timer that countdowns a mute timeout period. This mute timer may be reset upon receiving a fail silent test message sent by a master on the I2C bus in slave mode, or, in the master mode, from itself through the BP I2C core module. If the mute timeout period expires, the control unit may disable the I2C bus controller from transmitting on the I2C bus. The control unit may format CRC values and byte count values into messages, and include a byte counter to compare actual bytes received to the expected byte count indicated by a received byte count value.

Abstract:

An autonomous controller, comprised of a state knowledge manager, a control executor, hardware proxies and a statistical estimator collaborates with a goal elaborator, with which it shares common models of the behavior of the system and the controller. The elaborator uses the common models to generate from temporally indeterminate sets of goals, executable goals to be executed by the controller. The controller may be updated to operate in a different system or environment than that for which it was originally designed by the replacement of shared statistical models and by the instantiation of a new set of state variable objects derived from a state variable class. The adaptation of the controller does not require substantial modification of the goal elaborator for its application to the new system or environment.

09/967277

Inventors:

Robert Rasmussen - Rancho Palos Verdes CA, US

International Classification:

B62D 55/26

US Classification:

305191, 305201, 298911

Abstract:

A grouser shoe for track drives commonly utilized by industrial and commercial equipment (e. g. , bulldozers, backhoes, cranes, etc. ) including a supportive pad and a ground engaging bar, the ends of such bar being bent to form wings, and method of manufacture thereof. The center portion of the bar provides the primary transmission of driveforce from the vehicle to the ground, while the wings provide for significant reduction in vibration, facilitate steering, provide easier turning, and extend the service life of the grouser shoe.

Assignee:

Industrial Parts Depot - Torrance CA

International Classification:

D06F 7900

US Classification:

37141R

Abstract:

A router bit for use with earth-moving equipment such as tractor scrapers, bucket loaders and dozers, composed of two parts, one affixed permanently to the apparatus and the other, which comprises the cutting edge, separable from the former for ease of replacement when worn and ineffective, thus obviating the need for expensive and laborious replacement of the whole router bit assembly. The upper and lower parts are joined by interlocking fingers and secured further by flex pins. The lower part, by means of a bar-like extension affixed to and positioned generally diagonally across the length of either side thereof, is prevented from lateral movement.

US Classification:

370 859

Abstract:

This is a distributed computing system providing flexible fault tolerance; ease of software design and concurrency specification; and dynamic balance of the loads. The system comprises a plurality of computers each having a first input/output interface and a second input/output interface for interfacing to communications networks each second input/output interface including a bypass for bypassing the associated computer. A global communications network interconnects the first input/output interfaces for providing each computer the ability to broadcast messages simultaneously to the remainder of the computers. A meshwork communications network interconnects the second input/output interfaces providing each computer with the ability to establish a communications link with another of the computers bypassing the remainder of computers. Each computer is controlled by a resident copy of a common operating system. Communications between respective ones of computers is by means of split tokens each having a moving first portion which is sent from computer to computer and a resident second portion which is disposed in the memory of at least one of computer and wherein the location of the second portion is part of the first portion.
