A thermal energy controller system useful in medical procedures includes a controller coupled to a probe, and a thermal element to vary probe temperature. The controller includes memory storing a non-continuous algorithm that permits user-selectable settings for various probe types such that controller operation is self-modifying in response to the selected probe setting. Probe output power Pout is constant in one mode to rapidly enable probe temperature to come within a threshold of a target temperature. The controller can then vary Pout dynamically using a proportional-integral-derivative (PID) algorithm Pout=Kp·P+Ki·I+Kd·D, where feedback loop coefficients Kp, Ki, Kd can vary dynamically depending upon magnitude of an error function e(t) representing the difference between a user-set desired target temperature and sensed probe temperature. Advantageously, target temperature can be rapidly attained without overshoot, allowing the probe system to be especially effective in arthroscopic tissue treatment.

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.

Disclosed herein are methods and systems for transmitting streams of data. In one embodiment, a method comprises the steps of: receiving a stream of data; organizing the stream of data into a plurality of packets; generating a packet watermark associated with the stream of data; combining the packet watermark with each of the plurality of packets to form watermarked packets; and transmitting at least one of the watermarked packets across a network. The present invention also relates to: receiving at least one packet that has been transmitted across a network; analyzing at least one packet for a watermark; and authenticating the at least one packet using at least a portion of the watermark. The present invention also relates to generating packet watermarks and packet watermark keys.

RGB-Z imaging systems acquire RGB data typically with a high X-Y resolution RGB pixel array, and acquire Z-depth data with an array of physically larger Z pixels having additive signal properties. In each acquired frame, RGB pixels are mapped to a corresponding Z pixel. Z image resolution is enhanced by identifying Z discontinuities and identifying corresponding RGB pixels where the Z discontinuities occur. Thus segmented data enables RGB background substitution, which preferably blends foreground pixel color and substitute background color. The segmented data also enables up-sampling in which a higher XY resolution Z image with accurate Z values is obtained. Up-sampling uses an equation set enabling assignment of accurate Z values to RGB pixels. Fixed acquisition frame rates are enabled by carefully culling bad Z data. Segmenting and up-sampling enhanced video effects and enable low cost, low Z resolution arrays to function comparably to higher quality, higher resolution Z arrays.

Methods for adapting the operation of a system in response to the detection of embedded watermarks from a digital host content are provided. A digital host content is received and examined for the presence of watermarks. In response to the detection of embedded watermarks and in accordance with the value, type, density or spacing of the detected watermarks, one or more system reactions may take place. These reactions include conditionally allowing the system to resume its normal operation, prohibiting the system from resuming its normal operation, degrading the quality of the digital host content or changing the security status of the digital host content. In response to the extraction of weak watermarks that do not meet the desired system requirements, the extraction operation may be modified or extended to enable the detection of strong watermarks.

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.

A network system which includes a plurality of processing entities, an interconnect device coupled to the plurality of processing entities, a memory system coupled to the interconnect device and the plurality of processing entities, a network interface unit coupled to the plurality of processing entities and the memory system via the interconnect device. The network interface includes a memory access module and a packet classifier. The memory access module includes a plurality of parallel memory access channels. The packet classifier provides a flexible association between packets and the plurality of processing entities via the plurality of memory access channels.

A method and system for providing condition information associated with an entity being analyzed. The method includes presenting nodes corresponding to components of the entity according to a tree-like configuration, and providing condition information associated with at least one of the components using the nodes.

A self-configuring distributed packet switch which operates in wavelength division multiplexed (WDM) and time division multiplexed (TDM) modes is described. The switch comprises a distributed channel switching core, the core modules being respectively connected by a plurality of channels to a plurality of high-capacity packet switch edge modules. Each core module operates independently to schedule paths between edge modules, and reconfigures the paths in response to dynamic changes in data traffic loads reported by the edge modules. Reconfiguration timing between the packet switch modules and the channel switch core modules is performed to keep reconfiguration guard time minimized. The advantage is a high-capacity, load-adaptive, self-configuring switch that can be distributed to serve a large geographical area and can be scaled to hundreds of Tera bits per second to support applications that require, very high bandwidth and a guaranteed quality of service.

An automated map generator that can be used for creating new maps for uncharted areas, augmenting uncompleted maps, or creating maps for areas that are changing dynamically. One or more mobile devices include location based technology that operates to identify a current location for the mobile device and report that location to the map creation application. If the location of the mobile device is within an active mapping region, the map creation device can instruct the mobile device to report its location on a more frequent basis and then commence to map out the route to the mobile device. As the route is mapped out, a new map of the territory is created. As subsequent devices enter into that area (including navigational systems), the updated mapping information is provided to the device and can then be augmented by future location readings or can simply be used by the device.

The invention provides a USB storage device and an access control method thereof. An access control module is provided on the USB storage device. The storage space is divided into at least one data storage entity. Each user's access right to each data storage entity is set and stored in the USB storage device as an access control list. The process between the USB storage device's being connected with a USB host and its being disconnected from the USB host is one session. When a session is established, the user provides authentication information for the USB device to authenticate him/her, and saves the user information used in the current session. In the current session, when the host of the user issues an access request for the data storage entity on the USB storage device, the access control module queries the access right list based on the user information in the current session to determine whether the user has an access right to the requested data storage entity. When the user does not have the access right to the data storage entity, the access control module denies the user's access request for the data storage entity.
