    Abstract: An interactive input system comprises a display surface and processing structure communicating with the display surface. The processing structure presents on the display surface at least one graphic object, the graphic object having properties and a respective solution state comprising a value of at least one property. The processing structure in response to gesture input manipulates the value of the at least one property, and provides an indication as to whether the graphic object is in its solution state in response to the application of a predetermined amount of pressure against the display surface in association with the graphic object. A method and computer readable medium are also provided.

    Abstract: Embodiments of the present invention include systems for determining locations of UWB transmitters. The system (100) includes multiple UWB receivers (104) for receiving a UWB signal (120) emitted by a UWB transmitter (106). Each receiver (104) includes: RF amplifiers (306) arranged in a cascade structure, the RF amplifiers (306) receive and amplify the UWB signal; multiple baseband blocks (308), each of the baseband blocks is coupled to the corresponding RF amplifier (306) and taps an output signal from the corresponding RF amplifier; and a processor (320) coupled to the multiple baseband blocks (308), the processor processes output signals from the multiple baseband blocks (308) to identify the UWB signal (120). The system (100) also includes a server (110) coupled to the multiple receivers (104), the server (110) receives the identified UWB signals from the multiple receivers (104) and determines the location of the UWB transmitter (106) using the identified UWB signals.
