Abstract: A worksite management system for a worksite includes a sensor module associated with each of one or more machines working on the worksite. The sensor module generates a signal indicative of a location of a corresponding one of a machine from the one or more machines. An on-board controller associated with each of the one or more machines receives the signal corresponding to the location of the corresponding one of the machine on the worksite, and looks up the location of the corresponding one of the machine in at least one of a pre-generated or learned terrain map of a network of haul routes. The on-board controller identifies at least one condition of the haul route at the looked-up location, and then generates an alert for an operator to perform one or more recommended actions with respect to an operating parameter of the corresponding one of the machine.

Abstract: Disclosed herein is a system and method for determining the compaction of terrain based on rolling resistance. The system comprises a work machine configured to move along a route along the terrain, a navigation system configured to generate route data indicative of the route, a sensor configured to generate operating parameter data indicative of an operating parameter of the work machine moving along the route, and a processing unit. The processing unit is configured to process the operating parameter data to generate rolling resistance data indicative of the resistance by the terrain to the movement of the work machine along the route, and to process the rolling resistance data to generate compaction data indicative of the compaction of the terrain along the route.

Abstract: A work machine is moved along a route over worksite terrain. Route data indicative of the route is recorded and an operating parameter data indicative of at least one operating parameter of the work machine is determined as the machine moves along the route. The operating parameter data is used to generate rolling resistance data indicative of the resistance of the terrain to the movement of the work machine as it moves along the route. Then the rolling resistance data is processed to generate compaction data indicative of the compaction of the terrain along the route.

Abstract: An electronic calendar device capable of maintaining and displaying the date of the Hebrew, sometimes referred to as the Jewish, calendar which is based on the lunar cycle. In addition it is capable of computing the day of the week a certain Hebrew date will fall and corresponding Hebrew/Gregorian dates. The device corrects for all regular and irregular variations of the Hebrew calendar over a period of 10 years using a simple card or chip containing only prewired connections. Also displayed are the days of the week and the calendar year. The device requires a one pulse per day input which is available from standard electronic clock circuit chips in addition to the setting and computing input clock rates to be described.
