A load control management protocol, system, and method that address many different customers, individually, in geographic groups, or in other predefined groups to control at least one or more electrical power consuming appliances are disclosed. The computer-implemented protocol provides wired and wireless communication schemes that enable a utility to quickly and efficiently communicate commands and messages to end user devices. Specific electrically powered appliances and certain uses of electricity can therefore be managed by communicating with the controllers of those appliances, providing management of a utility load during peak price and consumption periods to prevent delivery interruptions.

The suture is released by opening and withdrawing the tip from the guide. The suture is recovered by using the guide to redirect the tip and puncturing the tissue opposite the first point of insertion. The tip grasps the suture and pulls the suture through the guide. The suture is pulled outside the wound, providing for rapid closure of the surgical incision. The guide is insertable within the wound to be closed and guides the surgical instrument at a predetermined angle from the longitudinal axis of the guide for optimum wound closure. The surgical instrument and method may be used to advantageously shorten and strengthen ligaments. For example, by gathering and reinforcing the round ligament that supports a woman's uterus with suture materials, surgeons can reposition and stabilize a retroverted uterus. Other devices may be also used in connection with retracting and reinforcing connective tissue. For example, rather than relying entirely on suture material to hold connective tissue in a retracted state, a device having one or more anchors may be inserted into connective tissue.

The present invention provides a temperature control unit for an electrostatic adsorption electrode that is capable of controlling the wafer temperature rapidly over a wide temperature range without affecting in-plane uniformity while high heat input etching is conducted with high wafer bias power applied. A refrigerant flow path provided in the electrostatic adsorption electrode serves as an evaporator. The refrigerant flow path is connected to a compressor, a condenser, and a first expansion valve to form a direct expansion type refrigeration cycle. A second expansion valve is installed between the electrostatic adsorption electrode and the compressor to adjust the flow rate of a refrigerant. This makes it possible to compress the refrigerant in the refrigerant flow path of the electrostatic adsorption electrode and adjust the wafer temperature to a high level by raising the refrigerant evaporation temperature. Further, a thin-walled cylindrical refrigerant flow path is employed so that the thin-walled cylinder is deformed only slightly by the refrigerant pressure.

An integrated optimization and control technique integrates an optimization procedure, such as a linear or quadratic programming optimization procedure, with advanced control, such as model predictive control, within a process plant in which the number of control and auxiliary variables can be greater than the number of manipulated variables within the process plant. The technique first determines a step response matrix defining the correlation between changes in the manipulated variables and each of the process variables that are used during optimization. A subset of the control variables and auxiliary variables is then selected to be used as inputs to a model predictive control routine used to perform control during operation of the process and a square M by M control matrix to be used by the model predictive control routine is generated. Thereafter, during each scan of the process controller, the optimizer routine calculates the optimal operating target of each of the complete set of control and auxiliary variables and provides the determined target operating points for each of the selected subset of control and auxiliary variables to the model predictive control routine as inputs. The model predictive control routine determines changes in the manipulated variables for use in controlling the process from the target and measured values for each of the subset of the control and auxiliary variables and the M by M control matrix.

A surgical instrument, guide, and method capable of being used for closure of peritoneum fascia, occlusion of bleeding vessels such as inferior epigastric, and for all uses related to accurately passing suture material through a guide into tissue. A tip of a surgical instrument in a standard suture- / needle-driving position with a sharp tip that opens and closes with the surgeon grasping suture material with the sharp tip is provided.
