In a thin film transistor (1), a gate insulating layer (4) is formed on a gate electrode (3) formed on an insulating substrate (2). Formed on the gate insulating layer (4) is a semiconductor layer (5). Formed on the semiconductor layer (5) are a source electrode (6) and a drain electrode (7). A protective layer (8) covers them, so that the semiconductor layer (5) is blocked from an atmosphere. The semiconductor layer (5) (active layer) is made of, e.g., a semiconductor containing polycrystalline ZnO to which, e.g., a group V element is added. The protective layer (8) thus formed causes decrease of a surface level of the semiconductor layer (5). This eliminates a depletion layer spreading therewithin. Accordingly, the ZnO becomes an n-type semiconductor indicating an intrinsic resistance, with the result that too many free electrons are generated. However, the added element works on the ZnO as an accepter impurity, so that the free electrons are reduced. This decreases a gate voltage required for removal of the free electrons, so that the threshold voltage of the thin film transistor (1) becomes on the order of 0V. This allows practical use of a semiconductor device which has an active layer made of zinc oxide and which includes an protective layer for blocking the active layer from an atmosphere.

When a signal inputted to a pixel is erased by setting potentials of a gate terminal and a source terminal of a driving transistor to be equal, a current slightly flows through the driving transistor in some cases, which leads to occur a display defect. The invention provides a display device which improves the yield while suppressing the increase in manufacturing cost. When a potential of a scan line for erasure is raised, a potential of the gate terminal of the driving transistor is raised accordingly. For example, the scan line and the gate terminal of the driving transistor are connected through a rectifying element.

An improved system for accessing data within a distributed data storage network (“DDSN”) is disclosed. In a system implementing the disclosed invention, traffic is routed to individual slice servers within the DDSN in accordance with objective criteria as well as user-defined policies. In accordance with one aspect of the disclosed invention, when a data segment is written to a DDSN, the segment is divided into multiple data slices, which are simultaneously transmitted to different slice servers. In accordance with another aspect of the disclosed invention, when a data segment is read from a DDSN, a list of slice servers, each containing a data slice that could be used to reconstruct the requested data segment, is assembled, and sorted in accordance with a preference rating assigned to each of the slice servers. Sufficient data slices to reconstruct the data segment are then read in accordance with the preference ranking of the slice servers.

A two-component fluid dispenser which can accurately mix two liquids of varying viscosity and then precisely deliver the mixture formed in discrete amounts. The mixture of the two components is delivered from a single delivery tube in a manner such that none of the mixture remains within the delivery tube at the completion of each mixing and delivery cycle. In one form of the apparatus, the single delivery tube of the apparatus is operably coupled with conventional hypodermic syringes of various sizes so that different fluids can be mixed in different ratios.

The present invention provides improved electrosurgical instruments and systems having electrocautery energy supply conductors that provide inhibited current leakage and methods of performing a robotically controlled minimally invasive surgical procedure while preventing unintended capacitive coupling. A surgical instrument generally comprises an elongate shaft having a proximal end and a distal end and defining an internal longitudinally extending passage. An electrocautery end effector is coupled to or disposed at the distal end of the shaft. An interface or tool base is coupled to or disposed at the proximal end of the shaft and removably connectable to the robotic surgical system. Typically, an independent electrical conductor extends from the interface to the end effector to transmit electrical energy to tissue engaged by the end effector. A sealed insulation tube extends within the passage and over the conductor. A separation is maintained between the sealed insulation tube and the conductor.

A computer gaming system and method of operation thereof are provided that both drastically reduce the cost of gaming stations and allow contemporaneous access to multiple game programs from a single gaming station. The computer gaming system of the present invention allows for transparent modifications and upgrades to the gaming programs by executing gaming programs on a server/host computer connected to a plurality of client/terminal computers via communication pathways. Each client/terminal computer comprises a client/terminal program that allows input and output streams of the gaming program executed on the server/host computer to be separated and redirected to the client/terminal computers. Since the gaming programs are executed entirely on the server/host computer, with only wagering input and display output operations being executed on the client/terminal computers, the cost of the hardware and software required for each client/terminal computer is greatly reduced. A patron of a client/terminal computer can access any of the gaming programs executed on the server/host computer. Modifications and upgrades of the gaming programs only need to be performed on the server/host computer. By using a stereo head-mounted display together with a joystick input device and wireless communication pathways, the present invention allows a patron to participate in a mobile gaming environment.

Exploiting the substantive reciprocity of internode channel responses through dynamic, adaptive modification of receive and transmit weights, enables locally enabled global optimization of a multipoint, wireless electromagnetic communications network of communication nodes. Each diversity-channel-capable node uses computationally efficient exploitation of pilot tone data and diversity-adaptive signal processing of the weightings and the signal to further convey optimization and channel information which promote local and thereby network-global efficiency. The preferred embodiment performs complex digital signal manipulation that includes a linear combining and linear distribution of the transmit and receive weights, the generation of piloting signals containing origination and destination node information, as well as interference-avoiding pseudorandom delay timing, and both symbol and multitione encoding, to gain the benefit of substantive orthogonality at the physical level without requiring actual substantive orthogonality at the physical level.
