Title: Regulating water treatment agent dosage based on operational system stresses
Inventor: HOOTS JOHN E
IPC: G01N21/64
Filed: 1995-02-13
Granted: 2006-06-27
Abstract: A target-specie responsive regulation of water treatment agent feed is achieved by the monitoring of a subject target-specie indicator. A target specie in a sample taken from the system is selected as the subject target-specie indicator, or instead an incipient reagent is added to the system sample to form a subject target-specie indicator. Such a formed subject target-specie indicator comprises a combination of the incipient reagent and a target specie. The subject target-specie indicator might then monitored by fluorescence analysis of the sample to determine at least one fluorescence emission value that can be correlated to the in-system concentration of the target specie. In combination with an inert tracer, the system consumption for the target specie can be determined. A responsive adjustment of the in-system concentration of a water treatment agent can be made.

Title: Method and system for managing retail promotion events
Inventor: MAGOWAN CHARLES
IPC: H04L12/16
Filed: 2004-11-24
Granted: 2016-03-29
Abstract: Disclosed are techniques for the creation, communication, negotiation, and storage of promotion events between trading partners. A promotion event is managed between a retailer and a vendor each having an associated computer in communication with a data network. The promotion event is defined to include terms, including an event description and a designated items description. The terms are situated in fields of a promotion event record. The designated items description is matched to a list of items stored in an item table. This list of items is authorized for sale by the retailer. A validation operation includes determining whether the fields in the promotion event record conform to requirements of a deal sheet associated with the retailer. The promotion event record is stored as a deal in a deal transaction storage medium. The retailer computer is provided with read access to the stored deal. The retailer can then negotiate the stored deal with the vendor. The vendor can revise the terms of the stored deal as desired. Further negotiation can occur until the deal is accepted.

Granted: 2010-02-09
Abstract: A system for positioning a spray apparatus relative to a surface, in which the spray apparatus directs a liquid coating such as paint toward the surface for applying the liquid to the surface in a spray pattern. A light beam emitter is interconnected with the spray apparatus, and emits a light beam in a predetermined orientation relative to the spray pattern such that the light beam strikes the surface in a center defined by the spray pattern when the spray apparatus is positioned a predetermined distance from the surface. The light beam is oriented such that the distance of the spray apparatus corresponds to .a distance providing optimal application of the coating to the surface, to minimize waste and overspray. The angle of the light beam relative to the spray pattern can be adjusted so as to vary the distance from the surface at which the light beam coincides with the center of the spray pattern, to provide a gauge for optimal spray application for varying spray parameters.
