Abstract: A peripheral device is connectable to a computer having one of a first interface and a second interface. The first interface communicates with the peripheral device over a differential data connection having a first data conductor and a second data conductor. The second interface communicates with the peripheral device over a clock conductor and a single ended data connection which includes a data conductor. The peripheral device has first and second communication conductors configured for connection to the first and second data conductors in the differential data connection when the computer includes the first interface and is configured for connection to the first data conductor in the single ended data connection and the clock conductor when the computer is provided with the second interface.

Abstract: A keyboard selectively operable to convey data to and from a host or personal computer (PC) through a universal serial bus (USB) port and/or a personal system/2 (PS/2) port. The keyboard is preferably connected to both the USB port and PS/2 port on the host or PC, if available. Preference is given to communicating data from the keyboard to the host or PC through the PS/2 port. However, if the PS/2 port is unavailable, not connected, or inoperative, the keyboard data are communicated to the host or PC through the USB port (assuming that it is available, operative, and connected). As soon as the PS/2 port on the host or PC is again connected to the keyboard, such data will again be communicated through the PS/2 port. In addition, the keyboard includes auxiliary USB ports to which USB-capable peripheral devices can be connected. USB data can then be communicated between the PC and the USB-capable peripheral devices via the keyboard and its connection to the USB port on the host or PC.

Abstract: An artificial nail having a three dimensional feature. The three dimensional feature may be a three dimensional representation of any known or imagined person, place or thing. The three dimensional feature may have a protrusion that is graspable. The protrusion may be used to assist in placing the artificial nail onto a fingernail or toenail. The artificial nail may include a tool or writing implement that may be extendible/retractable, movable and/or rotatable. The artificial nail may include removably attached three dimensional features. The three dimensional feature may include hair. The three dimensional feature may include a sound emitter or be designed to emit sound. The three dimensional feature may be plush or made from fabric. The artificial nail may include a power source and a light emitter to emit light from a portion of the three dimensional feature.

The first interface communicates with the peripheral device over a differential data connection having a first data conductor and a second data conductor. The second interface communicates with the peripheral device over a clock conductor and a single ended data connection which includes a data conductor. The peripheral device has first and second communication conductors configured for connection to the first and second data conductors in the differential data connection when the computer includes the first interface and is configured for connection to the first data conductor in the single ended data connection and the clock conductor when the computer is provided with the second interface.

Abstract: A educational water toy designed for mounting on a vertical surface, such as a bathtub wall, is disclosed. It consists of a variety of interlocking parts which can be arranged in various sequences. The various parts are designed to conduct water; control, or respond to, water flow; or to attach other parts to the vertical surface. The fluid-conveying and -operated toy has a reservoir, at least one activity component, a fluid conduit which provides fluid communication between the reservoir and the activity component, with the activity component being placed into motion by fluid exiting from the conduit, coupling structures interconnect the components in fluid communication, and attaching devices for removably attaching the components to the vertical surface in an orientation such that the fluid flows along the fluid flow path under the force of gravity. The various activity components may include a paddle wheel, a turbine, an hourglass member, a dipper, a sprayer and a squirter.
