Abstract: A disposable table cloth for umbrella tables. The table cloth, for use by diners, card players, picnickers or other people using the table, is disposable, so that the users may simply place it flat on the table top, use the table, and dispose of the table cloth when they are finished. The table cloth has no expensive components such as velcro, elastic, ties, strings, etc, thus making for low cost. The table cloth further has a top surface which users may lay flat on the table top in order to use the table. The table cloth has a slit extending from the rim of the table cloth to a aperture through which the pole of the umbrella may sit. In addition, the table cloth has adhesive, especially tacky adhesive, used to fasten and seal the table cloth slit together.

Abstract: The invention enables an operation to be monitored directly by a single person at a monitoring site. Certain predefined activities at one or more operating sites are automatically monitored. Information regarding these activities is conveyed to the monitoring site as directed by the person doing the monitoring. The information collected at the monitoring site is used to describe the status of the operation at a given time or the change in status of the operation over a period of time, and to verify information about the conduct of the operation supplied by third parties to the person monitoring the operation. The operation can be conducted at any number of operating sites and the operating sites can be separated by any distance. The monitoring site can be, and frequently is, geographically remote from the operating sites. Further, the monitoring site can be mobile, without affecting the monitoring capabilities of the invention.
