A programmable semiconductor device has a switch element in an interconnection layer, wherein in at least one of the inside of a via, interconnecting a wire of a first interconnection layer and a wire of a second interconnection layer, a contact part of the via with the wire of the first interconnection layer and a contact part of the via with the wire of the second interconnection layer, there is provided a variable electrical conductivity member, such as a member of an electrolyte material. The via is used as a variable electrical conductivity type switch element or as a variable resistance device having a contact part with the wire of the first interconnection layer as a first terminal and having a contact part with the wire of the second interconnection layer as a second terminal. By varying the electrical conductivity of the switch element, the state of connection of the via with the wire of the first interconnection layer and the state of connection of the via with the wire of the second interconnection layer may be variably set to a shorted state, an open-circuited state or to an intermediate state A two-state switch element includes an ion conductor for conducting metal ions interposed between the first and second electrodes. The second electrode is formed of a material lower in reactivity than the first electrode. The electrical conductivity across the first and second electrodes is changed by the oxidation-reduction reaction of the metal ions.

This relates to an event sensing device that includes an event sensing panel and is able to dynamically change the granularity of the panel according to present needs. Thus, the granularity of the panel can differ at different times of operation. Furthermore, the granularity of specific areas of the panel can also be dynamically changed, so that different areas feature different granularities at a given time. This also relates to panels that feature different inherent granularities in different portions thereof. These panels can be designed, for example, by placing more stimulus and / or data lines in different portions of the panel, thus ensuring different densities of pixels in the different portions. Optionally, these embodiments can also include the dynamic granularity changing features noted above.

Providing access to a resource via authorization data that conditionally defines the access by an expression that identifies the resource by name and by at least one property of the resource. An authorization service issues the authorization data (e.g., as a token) and evaluating authorization data received from a client. The authorization service evaluates the expression in the authorization data to identify the resource and determine the rights associated with the user for the resource. The authorization service implements role-based access control to control access to resources in a distributed, multi-site network.

A signal distribution system for distributing signals, such as for outdoor wireless networks, comprises a number of remote hubs, each of which can direct wireless signals to a number of antennas. The antennas are used to provide wireless service to the service users, such as mobile units, within their geographic coverage area. The remote hubs are connected to main hubs, which are usually located centrally. Each main hub can support a number of remote hubs. The main hubs are connected to a number of base stations (again usually located centrally) in a flexible and re-configurable manner using a switch matrix. Some remote hubs may also include switched matrices for a further level of signal routing.

One embodiment of the present invention includes a parallel processing unit (PPU) that performs pixel shading at variable granularities. For effects that vary at a low frequency across a pixel block, a coarse shading unit performs the associated shading operations on a subset of the pixels in the pixel block. By contrast, for effects that vary at a high frequency across the pixel block, fine shading units perform the associated shading operations on each pixel in the pixel block. Because the PPU implements coarse shading units and fine shading units, the PPU may tune the shading rate per-effect based on the frequency of variation across each pixel group. By contrast, conventional PPUs typically compute all effects per-pixel, performing redundant shading operations for low frequency effects. Consequently, to produce similar image quality, the PPU consumes less power and increases the rendering frame rate compared to a conventional PPU.

Methods, apparatus, and systems for signal continuity assessment using embedded watermarks are provided. The embedded watermarks are recovered from the content and one or more attributes associated with the recovered watermarks are identified. A continuity of the content can then be assessed in accordance with the one or more attributes. The continuity assessment may be based on a variety of factors, including but not limited to a determined heartbeat of the recovered watermarks, a density, separation, location, or extent, of the recovered watermarks, as well as information associated with the watermarks, such as a stego key, channel bits, packet numbers, a fingerprint, or the like.

An intrusion detection system (IDS) is capable of identifying the source of traffic, filtering the traffic to classify it as either safe or suspect and then applying sophisticated detection techniques such as stateful pattern recognition, protocol parsing, heuristic detection or anomaly detection either singularly or in combination based on the traffic type. In a network environment, each traffic source is provided with at least one IDS sensor that is dedicated to monitoring a specific type of traffic such as RPC, HTTP, SMTP, DNS, or others. Traffic from each traffic source is filtered to remove known safe traffic to improve efficiency and increase accuracy by keeping each IDS sensor focused on a specific traffic type.
