A wireless, multi-modal access device and system adapted to integrate a number of communications networks operating in differing communication modes to facilitate transfer of communication links during a communication session to promote efficient use of the communication networks. The system includes a plurality of Universal Multi-Modal Access Devices UMMAD that are capable of operating at different frequencies and different protocols (TDMA, AMPS, CDMA, GSM, PCS etc) to communicate with any one of a number of Wide Bandwidth Gateways (WBG), which are each capable of communication using one or more of the protocols. The communication links may be switched from one WBG to another or from one protocol to another during a communication session to continue the session under the control of a Universal System Traffic Controller. Numerous other applications of the UMMADs for unique identification and e-commerce are disclosed.

A lawn mower having selectively drivable wheels, includes dirigible front drive wheels, a pair of right and left rear drive wheels, a body frame, an engine supported by the body frame, a mower unit vertically movably supported by the body frame forwardly of the rear drive wheels, a change speed device for changing a speed of drive from the engine, a front wheel driving device for transmitting drive from the change speed device to the front wheels, a left rear wheel driving device for transmitting drive from the change speed device to a right axle of the left rear wheel, a right rear wheel driving device for transmitting drive from the change speed device to a left axle of the left rear wheel, and rear wheel clutches associated with the left rear wheel driving device and the right rear wheel driving device, respectively, for selectively connecting and disconnecting drive. The rear wheel clutches are operable by an interlocking mechanism in response to a displacement to the front drive wheels from a straight running posture, to disconnect drive transmission to one of the rear drive wheels moving along an inner track of turning of the vehicle body. The interlocking mechanism has a link mechanism operatively connecting a steering mechanism for steering the front drive wheels to each of the rear wheel clutches, and extending over the mower unit.

The present device is a microchannel separator that uses a separation driving force created by an electric field. An ionic fluid flows through the microchannels and is subjected to an electric field by two spaced apart parallel electrodes possessing an electric charge. The ions in the ionic fluid are attracted towards the charged electrodes and thus are concentrated in the region of flow near the charged electrodes and depleted from the central region of flow between the charged electrodes. The charged electrodes are insulated from the ionic fluid by an impermeable barrier which prevents arcing and adherence of the ions to the charged electrodes. After a sufficient length of passage of the ionic fluid through a main channel two blocking plates separate the flow into a central and two outer output channels. The central channel draws a portion of the ionic fluid from the central region of the main channel that has fewer ions than the ionic fluid in the regions near the charged electrodes. The concentrated ionic fluid in the outer channels is discharged separately from the central channel.

A planarization apparatus and method that thins and planarizes a substrate by grinding and polishing the rear surface of the substrate with high throughput, and that fabricates a semiconductor substrate with reduced adhered contaminants. A planarization apparatus that houses various mechanism elements in semiconductor substrate loading / unloading stage chamber, a rear-surface polishing stage chamber, and a rear-surface grinding stage chamber. The throughput time of the rear-surface polishing stage that simultaneously polishes two substrates is typically about double the throughput time of the rear-surface grinding stage that grinds one substrate.

A method for the production and use of multipotential stem-like cells is disclosed. The preparation utilized in this method is characterized by the contact of low level electrical currents with cultures of fibroblasts or other -blast cells enriched by fibroblast growth factor and other nutrients. The electrical current is conducted by means of silver electrode(s) brought into contact with the fibroblast preparation or other -blast cell preparation cultured for that purpose. The cells of the preparation may be used in applications that require the use of stem cells, including therapeutic applications, without the need for human fetuses or human umbilical cords or penetrating human bones to extract bone marrow. The cells thus produced have the ability to redifferentiate into endoderm, ectoderm and mesoderm to form any tissue of the body except the lens of the eye. Any cell found in the blood may be copied and multiplied. Any tissue of the body may be copied and multiplied with the lone exception of the lens of the eye as noted above.

The instant dental bridge is one used in surgical operations in areas of missing teeth between abutment teeth includes: an artificial tooth or teeth (2) formed with slots (6) in recessed parts near to the gum; a connecting body (1) which has through holes (3) formed in positions corresponding to the slots (6) and projections joined onto the abutment teeth, and of which the entire surface, except the surfaces (5′) in contact with the abutment teeth, is covered by the artificial tooth (2) or by the same material as the artificial tooth; and wires (8) for securing the abutment teeth and the connecting body (1) to each other, by being wound through gaps (7) neighboring the abutment teeth and through the slots (6) and the through holes (3).

An ink cartridge has an ink pack that holds ink and a case that holds the ink pack. The case has a case body forming an ink pack storage space R, and a cover that is removably attached to the case body. An ink supply opening is formed in the front wall of the case body, and a body-side pedestal protruding from the interior of the case body toward the cover inside the case is formed at the opposite end as the ink supply opening. When the cover is attached to the case with an ink pack inside, the back end part of the ink pack is held between a cover-side pedestal protruding from the interior of the cover and the body-side pedestal. The back side of the body-side pedestal forms an exterior recess on the case that can be used as a fingerhold.

The present invention relates to a ground terminal for an electronic device. The ground terminal comprises a ground cable connecting device, an electrical switch, an electrical conductor connecting the ground cable connecting device to the electrical switch. The ground terminal and its ground cable connecting device is configured so that the electrical switch is brought in to a first mode in response to an electrical wire being connected to the ground cable connecting device, the first mode being a mode in which the switch establish electrical conduction between an electrical circuit of the electronic device and the ground cable connecting device. Moreover, the ground terminal and its ground cable connecting device is configured so that the electrical switch is in a second mode when no electrical wire is connected to the ground cable connecting device, the second mode being a mode in which the switch is electrically isolating the electrical circuit of the electronic device and the ground cable connecting device from each other.
