USB cable and method for charging battery of external apparatus by using USB cable

Abstract: A USB cable according to the present invention has a USB connector connected with a USB port of a PC (Personal Computer), a phone connector connected with a connector of an external connector such as a mobile phone, a control unit, which is situated between the USB connector and the phone connector, for charging a battery of the mobile phone by using power supplied from the USB port of the PC and for transmitting and receiving data with the PC and the mobile phone, and a cable for connecting the USB connector and the phone connector with the control unit respectively.

Method and apparatus for facilitating game play and generating an authenticatable audit-trail

Abstract: A remote gaming systems whereby a player can gamble against a wagering establishment or state-run lottery from a remote location on a personal computer or portable computer device where it is unnecessary to establish an on-line connection with a host computer associated with the wagering establishment, the gaming computer having associated gaming software for providing at least one wagering opportunity and enabling the player to obtain gambling credit and cash-out any resulting winnings, the host computer enabling the player to purchase and redeem gambling credit at the remote location in one embodiment of the invention using cryptographic protocols such as through a series of authenticatable message exchanges between the player and the wagering establishment, the gaming computer and the host computer directly on-line, or the gaming computer having a detachable tamper-resistant or tamper-evident credit module associated therewith or for use with a personal computer being provided to the player with preinstalled or preloaded gambling credit, the gaming system also enabling participation in future events of which the outcome is uncertain such as, for example, a lottery whereby the player makes selections on a gaming computer at a remote location.

Creating Music by Listening

Abstract: Automated creation of new music by listening is disclosed. A method to create new music may comprise listening to a plurality of music, learning from the plurality of music, and performing concatenative synthesis based on the listening and the learning to create the new music. The method may be performed on a computing device having an audio interface, such as a personal computer.

ICT Use in the Developing World: An Analysis of Differences in Computer and Internet Penetration

Abstract: Computer and Internet use, especially in developing countries, has expanded rapidly in recent years. Even in light of this expansion in technology adoption rates, penetration rates differ markedly between developed and developing countries and across developing countries. To identify the determinants of cross-country disparities in personal computer and Internet penetration, both currently and over time, we examine panel data for 161 countries over the 1999-2004 period. We explore the role of a comprehensive set of economic, demographic, infrastructure, institutional and financial factors in contributing to the global digital divide. We find evidence indicating that income, human capital, the youth dependency ratio, telephone density, legal quality and banking sector development are associated with technology penetration rates. Overall, the factors associated with computer and Internet penetration do not differ substantially between developed and developing countries. Estimates from Blinder-Oaxaca decompositions reveal that the main factors responsible for low rates of technology penetration rates in developing countries are disparities in income, telephone density, legal quality and human capital. In terms of dynamics, our results indicate fairly rapid reversion to long run equilibrium for Internet use, and somewhat slower reversion for computer use, particularly in developed economies. Financial development, either measured as bank lending or the value of stocks traded, is also important to the growth rate of Internet use.

Wireless control device

Abstract: A wireless control device includes a small, lightweight housing worn by an operator, for example on the operator's wrist, and a controlled device, for example a personal computer. Several optical emitters, preferably light emitting diodes operating in the infrared range, and several optical detectors are provided on the housing. At least one x-axis emitter-detector pair operates to detect an x-direction of a pointing motion or gesture, and at least one y-axis emitter-detector pair operates to detect a y-direction of a pointing motion or gesture. This motion can then be used to cause a response in the controlled device. For example, angles of the operator's hand at the wrist can be interpreted to induce motion of a cursor on a computer display. The device may also include a motion sensor, an environmental condition sensor, or a voice recognition sensor, and can also be adapted for gesture recognition and image scanning applications.
