Building virtual structures with physical blocks

Abstract: We describe a tangible interface for building virtual structures using physical building blocks. We demonstrate two applications of our system. In one version, the blocks are used to construct geometric models of objects and structures for a popular game, Quake II™. In another version, buildings created with our blocks are rendered in different styles, using intelligent decoration of the building model.

14-bit 2.2-MS/s sigma-delta ADC's

Abstract: This paper presents the design and test results of a fourth-order and sixth-order 14-bit 22-MS/s sigma-delta analog-to-digital converter (ADC) The analog modulator and digital decimator sections were implemented in a 035 /spl mu/m CMOS double-poly triple-level metal 33-V process The design objective for these ADC's was to achieve 85 dB signal-to-noise distortion ratio (SNDR) with less than 200 mW power dissipation Both modulators employ a cascade sigma-delta topology The fourth-order modulator consists of two cascaded second-order stages which include 1-bit and 5-bit quantizers, respectively The sixth-order modulator has a 2-2-2 cascade structure and 1-bit quantizer at the end of each stage An oversampling ratio of 24 was selected to give the best SNDR and power consumption with realizable gain-matching requirements between the analog and digital sections

Power conversion system

Abstract: In a power conversion system in which one or more converter cells are connected in series to form an arm for each phase, a control device includes a voltage command generating unit for generating a positive arm voltage command and a negative arm voltage command for each phase The voltage command generating unit includes an AC current control unit, a circulating current control unit, and a command distributing unit On the basis of inputted voltage commands, the command distributing unit subtracts voltage drop portions due to inductance values in the arms from respective voltages assigned as outputs of the positive arm and the negative arm, to distribute voltage components, thereby determining the positive arm voltage command and the negative arm voltage command

Touch screen, touch panel, and display device including the same

Abstract: A touch screen includes a base substrate, a bundle of rectangular wirings in a column direction including a plurality of detection column wirings that are electrically connected in common, and a bundle of rectangular wirings in a row direction including a plurality of detection row wirings that are electrically connected in common, the bundle of wirings being formed on the base substrate. Also, a plurality of block areas obtained by dividing an intersection area in which the bundle of wirings in the column direction and the bundle of wirings in the row direction intersect in a plan view are defined, and only the detection column wiring or only the detection row wiring is provided in each of the block areas.

Digital personal assistant docking station camera

Abstract: A docking station is adapted to operate with a personal digital assistant. The docking station includes an image sensor configured to acquire images, a sensor microprocessor coupled to the sensor, a vision microprocessor coupled to the sensor microprocessor and an instruction memory and a data memory, a communication interface coupled to the vision microprocessor, and configured to interface with a digital personal assistant and a computer system interface and a power supply. A housing of the docking station encloses the image sensor, the sensor microprocessor, the vision microprocessor and memories, the communications interface, and a power supply. During operation, a personal digital assistant is physically and electronically coupling to a top oblique surface of the housing.
