Formal control exists whenever a controlling variable evokes a response and there is point-to-point correspondence between the controlling variable and the response.

Robust adaptive model predictive controller with tuning to compensate for model mismatch

An MPC adaptation and tuning technique integrates feedback control performance better than methods commonly used today in MPC type controllers, resulting in an MPC adaptation/tuning technique that performs better than traditional MPC techniques in the presence of process model mismatch. The MPC controller performance is enhanced by adding a controller adaptation/tuning unit to an MPC controller, which adaptation/tuning unit implements an optimization routine to determine the best or most optimal set of controller design and/or tuning parameters to use within the MPC controller during on-line process control in the presence of a specific amount of model mismatch or a range of model mismatch. The adaptation/tuning unit determines one or more MPC controller tuning and design parameters, including for example, an MPC form, penalty factors for either or both of an MPC controller and an observer and a controller model for use in the MPC controller, based on a previously determined process model and either a known or an expected process model mismatch or process model mismatch range. A closed loop adaptation cycle may be implemented by performing an autocorrelation analysis on the prediction error or the control error to determine when significant process model mismatch exists or to determine an increase or a decrease in process model mismatch over time.

Method and system for providing communication context specific formality control

A system for automatically providing different levels of formality controls in a communication is disclosed, in which a formality level is determined based on a current communication context. The formality level is used to enable an appropriate level of automatic checking of the communication contents. The determination of a formality level for a communication may be based on any specific context information regarding the participants and/or contents of a communication. including but not limited to the relative positions of participants within an organizational hierarchy (“organizational distance”), the professional relationships of the participants (e.g. service provider to client/customer), the frequency of communications between participants, the geographic locations of participants, the number of previous errors in the communication contents, configurable participant preferences, express communication settings by participants, etc. The determined formality level may be used to enable any specific type or level of automatic message contents checking, including but not limited to various types and levels of spell checking (e.g. location specific spell checking), grammar checking, acronym substitution, cultural filtering, etc. The disclosed system may determine organisational distances based on the contents of user directories, such as lightweight directory access protocol (LDAP) directories.

Pedal-operated fluid dispensing apparatus

A fluid dispensing apparatus integrated within a pedal operated vehicle such as bicycles, tricycles, three-wheelers, four-wheelers and paddleboats is provided comprising a means for storing a fluid, such as water, a means for pressurizing said stored fluid, a means for controlling the release of said pressurized fluid in the form of one or more jets. In the preferred embodiment, the fluid is stored within one or more tanks or reservoirs, which tanks include a pump mechanism for pressurizing the tanks and the fluid stored therein. The pump mechanism includes pistons which are connected to the pedal cranks of the vehicle such that operation of the pedals so as to propel the vehicle simultaneously serves to reciprocate the pistons of the pump mechanism, thereby pressurizing the fluid tanks. Connected to the fluid storage tanks is at least one conduit or hose which is connected at its opposite end to a nozzle for dispensing the fluid. A trigger is incorporated with said nozzle so as to allow the user to alternatively release the pressurized fluid or stop the flow of said fluid. The nozzle may be incorporated on the handlebars or steering mechanism of the vehicle such that the fluid is released in the direction the vehicle is facing. A safety valve is also provided for the storage tanks to prevent the generation of dangerous pressure level.
