Method for accurately quoting wait time for a restaurant table
The inventive method uses data received concerning the status of various tables in the establishment, the criteria provided by the customer as well as the status of the meals being prepared in a variety of courses for customers already seated to best determine how much time a new customer will have to wait before a suitable table is available where the customer may be seated. When a customer enters the restaurant, they provide information to the hostess or host including the party size and various table preferences.

Periodically, once the data from all of the tables and the kitchen has been updated, the projected table turn times for each table are updated. With this updating having been accomplished, projected wait time for each party may be updated. Then, revised quoted wait times are given to customers while waiting.

Detection of voice inactivity within a sound stream
A method for identifying end of voiced speech within an audio stream of a noisy environment employs a speech discriminator. The discriminator analyzes each window of the audio stream, producing an output corresponding to the window. The output is used to classify the window in one of several classes, for example, (1) speech, (2) silence, or (3) noise. A state machine processes the window classifications, incrementing counters as each window is classified: speech counter for speech windows, silence counter for silence, and noise counter for noise. If the speech counter indicates a predefined number of windows, the state machine clears all counters. Otherwise, the state machine appropriately weights the values in the silence and noise counters, adds the weighted values, and compares the sum to a limit imposed on the number of non-voice windows. When the non-voice limit is reached, the state machine terminates processing of the audio stream.

Guidance method based on 3D-2D pose estimation and 3D-CT registration with application to live bronchoscopy
A method provides guidance to the physician during a live bronchoscopy or other endoscopic procedures. The 3D motion of the bronchoscope is estimated using a fast coarse tracking step followed by a fine registration step. The tracking is based on finding a set of corresponding feature points across a plurality of consecutive bronchoscopic video frames, then estimating for the new pose of the bronchoscope. In the preferred embodiment the pose estimation is based on linearization of the rotation matrix. By giving a set of corresponding points across the current bronchoscopic video image, and the CT-based virtual image as an input, the same method can also be used for manual registration. The fine registration step is preferably a gradient-based Gauss-Newton method that maximizes the correlation between the bronchoscopic video image and the CT-based virtual image. The continuous guidance is provided by estimating the 3D motion of the bronchoscope in a loop. Since depth-map information is available, tracking can be done by solving a 3D-2D pose estimation problem. A 3D-2D pose estimation problem is more constrained than a 2D-2D pose estimation problem and does not suffer from the limitations associated with computing an essential matrix. The use of correlation-based cost, instead of mutual information as a registration cost, makes it simpler to use gradient-based methods for registration.

Features for emergency bypass and external power supplies are included.
Pulsed backpressure mechanism for reduced FIFO utilization
The backpressure mechanism and method described here do not completely shut off the traffic when a queue is experiencing congestion. Instead of completely shutting off the traffic and waiting for the effects, a series of backpressure pulses are sent to the upstream stage for intermittently slowing the traffic between the upstream and downstream stages. These pulses of backpressure effectively slowly down the rate of the ingress traffic to the queue to a rate less than the egress rate. This allows queue utilization to slowly decrease. These pulses continue as long as the queue utilization is above a threshold called “Starving Threshold”. This technique allows much lower queue utilization, thus requiring smaller queues sizes.

Intelligent failover in a load-balanced network environment
A hash table in the network device driver maintains data on the traffic characteristics for each network interface (“NIC”) within a computing device. If one of the NICs in the computing device becomes unreliable, the cost function in the hash engine allows the software driver to initiate network traffic redistribution among the remaining reliable NICs in the computing device. Using this hash engine, the software driver is able to intelligently redirect each of the network connections on an unreliable NIC to a reliable NIC within the computing device, in a way that optimizes the distribution of network traffic across the remaining reliable NICs. Alternatively, if a connection is moved from an old NIC to a new NIC, the software driver can detect the moved connection and offload the moved connection to a hardware offload engine on the new NIC. With this approach, issues such as network interface overloading and computing device performance degradation may be more easily avoided when failing over network connections, thereby improving overall system performance relative to prior art techniques.

Magnetic recording head for perpendicular recording, fabrication process, and magnetic disk storage apparatus mounting the magnetic recording head
Embodiments of the invention provide a head which can prevent an external magnetic field form erasing a signal on the medium and whose main magnetic pole piece does not corrode during processing of the air bearing surface. In one embodiment, an anti-corrosion electrode is formed to apply a voltage to the main magnetic pole piece during processing of the air bearing surface. This retards corrosion of the main magnetic pole piece. Since a conductor (anti-corrosion wire) connected to this anti-corrosion electrode is made of a nonmagnetic material, concentration of an external magnetic field into the main magnetic pole piece can be suppressed. Consequently, since the magnetic leakage field emitted from the main magnetic pole piece is reduced, erasure of the signal on the medium can be prevented. In addition, since the anti-corrosion wire is connected to the upper core, this wire can be formed in the same wiring layer as a wire which connects the coil to a write terminal, resulting in a simplified manufacturing process.
