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.

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.

Apparatuses and methods for limiting the angle of incidence (AOI) of light reaching a dichroic filter. The apparatus may include an AOI filter element and the dichroic filter. The apparatus may be a sensor and may include a photodetector. The dichroic filter may be configured to prevent light having a wavelength outside a band pass region from reaching the photodetector and to pass light having a wavelength within the band pass. Physical limitations of the dichroic filter may preclude the dichroic filter from preventing high AOI light having a wavelength outside a band pass region from reaching the photodetector. The AOI filter element may be configured to prevent light having a high AOI from reaching the dichroic band pass filter and to propagate light having a low AOI to the dichroic band pass filter.

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.

The invention provides a force feedback man-machine interaction system and method based on the electromagnetic theory and mobile tracking. By the adoption of the force feedback man-machine interactionsystem and method, a manipulator is allowed to use gestures to control a robot and meanwhile can feel force feedback in the operation process. The interaction system includes five parts of a local control calculator, a mobile tracking platform, a gesture recognition sensor, a magnetic force generating device and a magnetic force sensing device. The interaction method is divided into two parts ofcontrol and feedback. The control part uses the non-contact gesture based on a visual interface as control information, while the feedback part uses the non-contact force magnetic force as feedback information to reduce the physical limitation when interacting, meanwhile a mobile tracking function is added, and it is ensured that the magnetic force generating device and the magnetic force sensingdevice can keep relative positions and postures of the magnetic force generating device and the magnetic force sensing device unchanged, so that the problem of too little stress caused by the attenuation of a magnetic field is reduced.

Systems and methods for communicating information within a business organization network using a one or more communication bands on a HF communication network.

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. The models created by this method may be further evaluated so that improvements can be made to the modeled processes. These improvements in modeled processes may include restructuring the human-implemented aspects of the process to take into account the human's cognitive and physical limitations. The model may also be used to identify the information flow aspects of the human cognitive activities allowing the specification and implementation of changes in the information flow or quality to result in improved human workloads.

An antenna comprises a medium substrate and grounding units attached on the medium substrate. The antenna further comprises a metal structure attached on the medium substrate. The metal structure comprises an electromagnetic response unit, a metal open ring enclosing the electromagnetic response unit and a feeding point connected to an end of the metal open ring. The electromagnetic response unit comprises an electric-field coupling structure. This design increases the physical length of the antenna equivalently, so an RF antenna operating at an extremely low frequency can be designed within a very small space. This can eliminate the physical limitation imposed by the spatial area when the conventional antenna operates at a low frequency, and satisfy the requirements of miniaturization, a low operating frequency and broadband multi-mode services for the mobile phone antenna. Meanwhile, a solution of a lower cost is provided for design of the antenna of wireless communication apparatuses.

The invention discloses a realization method for NVMe extension and a solid state disk. The method is characterized by comprising the steps of querying a no-map management table in the SSD according to a logic space of a command after the SSD receives the reading command of a host, judging whether the command is a no-map command or not, and if yes, directly setting a map status bit used for identifying whether no map exists or not in a completion queue entry to be 1, directly ending the command and performing return to the host; otherwise, reading data according to a logic space address of thecommand, and after the reading is finished, setting the map status bit to be 0 and performing return to the host; and after the host receives the completion queue entry, interpreting whether the mapstatus bit is 1 or not, and if yes, directly setting a cache corresponding to the command to be 0 by the host and performing return and application or direct return and application. By optimizing thereading processing process, data transmission between the SSD and the Host is reduced, so that the command response delay and the service time are greatly shortened and the actually measured bandwidthcan effectively break through physical limitation of PCIe.

State-based communication stations are capable of operating on two or more “states.” Principles of the present invention are used to allow the functionality that a multi-state communication station is equipped to change as a result of the current state of the station. The functionality of modern communication stations remains much less hindered by the physical limitations of the stations' physical construction and design. While the number of buttons in a communication station remains the same, the number of functions that such buttons may execute is multiplied by the number of “states” that exist for the station.
