An endoscope captures images of a surgical site for display in a viewing area of a monitor. When a tool is outside the viewing area, a GUI indicates the position of the tool by positioning a symbol in a boundary area around the viewing area so as to indicate the tool position. The distance of the out-of-view tool from the viewing area may be indicated by the size, color, brightness, or blinking or oscillation frequency of the symbol. A distance number may also be displayed on the symbol. The orientation of the shaft or end effector of the tool may be indicated by an orientation indicator superimposed over the symbol, or by the orientation of the symbol itself. When the tool is inside the viewing area, but occluded by an object, the GUI superimposes a ghost tool at its current position and orientation over the occluding object.

The subject invention provides for a feedback loop system and method that facilitate classifying items in connection with spam prevention in server and/or client-based architectures. The invention makes uses of a machine-learning approach as applied to spam filters, and in particular, randomly samples incoming email messages so that examples of both legitimate and junk/spam mail are obtained to generate sets of training data. Users which are identified as spam-fighters are asked to vote on whether a selection of their incoming email messages is individually either legitimate mail or junk mail. A database stores the properties for each mail and voting transaction such as user information, message properties and content summary, and polling results for each message to generate training data for machine learning systems. The machine learning systems facilitate creating improved spam filter(s) that are trained to recognize both legitimate mail and spam mail and to distinguish between them.

A mechanism for selectively disabling and enabling read caching based on past performance of the cache and current read/write requests. The system improves overall performance by using an autonomic algorithm to disable read caching for regions of backend disk storage (i.e., the backstore) that have had historically low cache hit ratios. The result is that more cache becomes available for workloads with larger hit ratios, and less time and machine cycles are spent searching the cache for data that is unlikely to be there.

MgO tunnel barriers are formed by depositing a thin layer of Mg on a suitable underlayer, and then directing oxygen and additional Mg towards the Mg layer. The oxygen reacts with the additional Mg and the Mg in the Mg layer to form a MgO tunnel barrier that enjoys excellent tunneling characteristics. The MgO tunnel barriers so formed may be used in magnetic tunnel junctions having tunneling magnetoresistance (TMR) values of greater than 100%. The highest TMR values are observed for junctions that have been annealed and that have a (100) crystallographic orientation.

A transmitter and receiver communicate using a modified superposition coding scheme. The transmitter transits superposition symbols which include a near end symbol for a near receiver and a far end symbol for a far receiver. The transmitter modifies the near end symbol depending on the far end symbol prior to transmission. Specifically, the near end symbol may be mirrored around the real or imaginary axis. The near receiver generates mirrored superposition symbols by applying mirroring to each received superposition symbol around at least one of the real axis and the imaginary axis in response to the value of the received symbol. The mirroring may remove the uncertainty of the far end symbol value allowing a simpler decision for the near end symbol. The mirroring performed by the transmitter and the near receiver will negate each other for the near end symbol thereby allowing a simplified near end receiver operation.

A method and apparatus to improve the performance of a SCSI write over a high latency network. The apparatus includes a first Switch close to the initiator in a first SAN and a second Switch close to the target in a second SAN. In various embodiments, the two Switches are border switches connecting their respective SANs to a relatively high latency network between the two SANs. In addition, the initiator can be either directly connected or indirectly connected to the first Switch in the first SAN. The target can also be either directly or indirectly connected to the second Switch in the second SAN. During operation, the method includes the first Switch sending Transfer Ready (Xfr_rdy) frame(s) based on buffer availability to the initiating Host in response to a SCSI Write command from the Host directed to the target. The first and second Switches then coordinate with one another by sending Transfer Ready commands to each other independent of the target's knowledge. The second switch buffers the data received from the Host until the target indicates it is ready to receive the data. Since the Switches send frames to the initiating Host independent of the target, the Switches manipulate the OX_ID and RX_ID fields in the Fibre Channel header of the various commands associated with the SCSI Write. The OX_ID and RX_ID fields are manipulated so as to trap the commands and so that the Switches can keep track of the various commands associated with the SCSI write.
