The present invention is a voltage mode digital controller for low-power high-frequency dc-dc converters that has recovery time approaching physical limitations of a given power stage. It consists of a digital controller with load transient response approaching physical limitations of a given power stage that is suitable for low-power SMPS. In one aspect the invention is a method of utilizing a continuous-time digital signal processor (CT-DSP) for regulation of the operation of switch-mode power supplies. A CT-DSP can be used to instantaneously detect changes of voltage or current during transition periods and immediately perform control action that results in the fastest possible response. The invention may include current program mode controllers for SMPS where the input current is sensed as well as power factor correction rectifiers (PFC), where often input voltage, input current and output voltage are sensed. Upon sensing a deviation in the input voltage the CT-DSP is utilized to apply a switch-mode power operation whereby the controller switches between continuous-time and digital function.

Real-time control of a dynamical system is provided by determining control variables that get as close as possible to producing a desired response. Additional consideration of physical limitations leads to a convex Quadratic Program with inequality constraints that needs to be solved in real-time. A new active set algorithm is described to solve the convex Quadratic Program efficiently that meets real-time requirements. Based on the key observation that the physical limitations of the system translate to optimal active sets that remain relatively unchanged over time (even though the actual optimal controls may be varying), starting guesses for the active set obtained from the final iterate in the previous time period greatly reduces the number of iterations and hence allows the Quadratic Programs to be solved to convergence in real-time.

To overcome the physical limitation of the display screen size, some computing devices may use the display screen as a window to show a subset of a larger “virtual desktop”. For example, a laptop with an 800×600 pixel display may show a subset of a 1280×1024 pixel virtual desktop. The user then manipulates scrollbars on the sides of the display to move the window to the portion of the virtual desktop he wishes to view. The display screen may pose a particular problem for personal digital assistants (PDAs), cell phones, and other handheld devices which have relatively small displays. A hand held device of the present disclosure is its own mouse, such that a virtual desktop may be navigated by moving the device itself to display desired portions of the virtual desktop on the screen of the device.

Various methods and systems for auctioning mutually exclusive items such as golf tee times, restaurant reservations, concert tickets or hotel reservations are disclosed. Mutually exclusive can refer to items that cannot be possessed simultaneously because of physical limitations or to multiple items that could be simultaneously physically possessed but the bidder would only want possession of, at most, one of the items. An electronic auction method therefore performs the following operations: (1) an ordered processing of ranked bids to compare currently active bids with current winning bids to determine the new winning bids; (2) notifying unsuccessful bidders via e-mail to increase their bids; (3) comparing the new bid amount to all outstanding active and winning bids if the unsuccessful active bid is increased; (4) designating the active bid an inactive bid and designating the next highest ranked bid as the user's current active bid if the unsuccessful bid is not increased in the allotted time; and, (5) continuing the protocol until all bidders either have a winning bid or no remaining active bids. An auction system includes a Central Auction Controller (CAC) that allows sellers to list items for auction and users to enter bids and rank orderings. The CAC maintains a central database comprising a database of user information, a database of items and bids and a database of vendor information. Administration of the system is accomplished via an I / O device and CPU and an optional e-mail processor allows automated messaging to users. This methodology allows users to effectively bid on a large number of mutually exclusive items but receive at most one item at the end of the auction. This method has the favorable effects for the users of: (1) increasing the probability of successfully bidding for at least one item; (2) making the auction process more convenient by greatly reducing the need for actively monitoring the auction; and, (3) decreasing the possibility a user will be out bid at the last moment and receive no item. This method has the favorable effects for the seller of increasing the probability their listed items will sell and increasing the expected average sales price.

An apparatus utilizing additive interleaved switchmode (PWM) power conversion stages, having minimal or no output filter, to achieve high bandwidth or even ideally instantaneous power conversion. The additive process may involve voltage stacking of isolated PWM converters, which are interleaved in time, or may involve a single input power supply and inductively combining output currents of PWM power converters interleaved in time, with either additive circuit having minimal or no output filtering. This circuit may overcome limitations for the frequency of feedback control loops once thought to be physical limitations, such as, fundamental switching frequency, output filter delay and the Nyquist criteria.

A distributed resonator laser system using retro-reflecting elements, in which spatially separated retroreflecting elements define respectively a power transmitting and a power receiving unit. The retroreflectors have no point of inversion, so that an incident beam is reflected back along a path essentially coincident with that of the incident beam. This enables the distributed laser to operate with the beams in a co-linear mode, instead of the ring mode described in the prior art. This feature allows the simple inclusion of elements having optical power within the distributed cavity, enabling such functions as focusing / defocusing, increasing the field of view of the system, and changing the Rayleigh length of the beam. The optical system can advantageously be constructed as a pupil imaging system, with the advantage that optical components, such as the gain medium or a photo-voltaic converter, can be positioned at such a pupil without physical limitations.

An adaptive guidance system (AGS) regulates the altitude and heading of a parasail to arrive at a target at a prescribed altitude. Since the altitude profile depends both on unknown wing loading, and wind magnitude and direction, the AGS estimates the glide slope and wind on the fly and provides a command to a stability augmentation system (SAS) that results in the desired glide slope and heading by performing a sequence of maneuvers and sensing the response. According to one embodiment, the SAS operates in the linear region and includes a PID controller that uses the difference between the actual heading and heading command to create an actuator output. The actuator output is limited by a position / rate limiter that imposes the physical limitations of the response time of the actuator / servos and position limits to prevent entering the nonlinear region. Alternatively, an adaptive SAS operates in both the linear and nonlinear region and includes a neural network (NN) that receives an error signal (difference between a reference model and actual heading) which is used to adapt the weights of the NN.

A method for modeling task, activity and workload of various human-implemented processes.
