A bi-directional single conductor interrupt line is used in conjunction with a master only initiated data communication bus, to allow a slave device to submit a slave service request to a master device and to acknowledge master service requests from the master device. When not submitting a master service request, the master device maintains an interrupt line voltage at an idle state voltage by setting the interrupt line voltage through a pull resistor. The slave and master devices submit service requests by respectively driving or pulling the interrupt line voltage from the idle voltage to the service request voltage. The slave responds to a master service request or initiates the master servicing of a slave service request by subsequently driving the interrupt line back to the idle state voltage giving a slower slave ample time to prepare for a pending master initiated data transaction. The master detects the change in the interrupt line voltage from the request to the idle state and communicates to the now readied slave device through the data communication bus.

A method for determining the correct result and the correct guard and sticky bits to obtain a more accurate result in floating point divide operations is presented. An intermediate divide result or quotient is obtained from a multiply-add hardware pipeline of a floating point processor. Remainders are calculated using the floating point numbers divided, the unit of least precision, and the unit of least precision plus one to determine where the infinitely precise result is with respect to the digital representation of the estimated quotient. Evaluating these remainders and the initial floating point numbers and comparing their signs and magnitudes leads to a selection of one of three choices as the most accurate representation of the infinitely precise result as calculated in the inventive rounding method: the intermediate result minus the unit of least precision; the intermediate divide result; or the intermediate divide result plus the unit of least precision. Based on a rounding mode determined by the floating point operation, the correct guard and sticky bits are also determined and, which along with the most accurate intermediate divide result, are forwarded for accurate rounding in accordance with the IEEE standard for single and double precision floating point numbers.

The present invention provides a system and methods for automatic parameter determination in machine vision in general, and in object recognition in particular. Many machine vision systems use algorithms that demand the user to specify one or more parameters in order to adapt the behavior of the algorithm in dependence of the current application.

The present invention provides a method to automatically determine the most frequently used parameters in machine vision solely based on the input image itself. The method is explained in detail using an object recognition system as an example. In particular, the model generation process based on a model image of the object is explained. However, also other systems that use edge extraction algorithms, for example, can benefit from the present invention.

Once performance event information is supplied in real time in accordance with a progression of a performance, a time indicative of temporal relationship between at least two notes to be generated in succession is measured on the basis of the performance event information supplied in real time. Comparison is made between a preset rendition style determination condition including time information and the measured time, and a rendition style that is to be applied to a current tone to be performed in real time is determined on the basis of the comparison result. With the arrangement that a rendition style to be applied to the current tone is determined on the basis of the comparison result, it is possible to execute a real-time performance while automatically expressing a tonguing rendition style.

Keys 1, 2 are supported by a frame 3 in a freely swingable manner. Massive bodies 8, a lower limit stopper 10 and an upper limit stopper 11 are situated below keys 1, 2. Massive bodies 8 are supported by a frame 3 in a freely swingable manner and pivot in synchronization with key-depression. A lower limit stopper 10 restricts a lower limit of pivoting range of the massive bodies 8. An upper limit stopper 10 restricts an upper limit of pivoting range of the massive bodies 8. Fixing portions (erected potions) 3g1 for fixing the upper limit stopper 11 are provided on the frame 3 in one-to-one corresponding with keys 1, 2. The upper limit stopper 11 is fixed to the undersurface of the fixing portions 3g. An upper part of each fixing portion 3g is situated inside right and left side walls of each key 1, 2.

This invention provides methods for producing antibodies, wherein the methods comprise the step of administering an immunogen comprising both a target antigen and a background antigen to transgenic animals, into which a gene coding for the background antigen has been introduced. Since immunotolerance to the background antigens have thus been induced in the transgenic animals, the animals efficiently produce antibodies to target antigens.

A disposable absorbent article having improved interactive graphics is disclosed. The disposable absorbent article defines a front waist end, a back waist end, and a length which extends between the front and back waist ends. In particular embodiments, the article includes an active graphic disposed on the bodyside liner and/or outer cover, and the active graphic is positioned within one of a frontmost 30% and a backmost 30% of the article's length. In particular embodiments, the article includes an active graphic disposed on the article's bodyside liner and/or outer cover, and the active graphic consists essentially of insoluble ink. In particular embodiments, the article includes an active graphic disposed on the article's bodyside liner and/or outer cover, and the article is adapted to provide for an at least partial disappearance of the active graphic without requiring that the active graphic directly contact liquid to effect the at least partial disappearance.
