An orthodontic bracket or convertible buccal tube for use with arch wires has the usual mesial distal extending slot having one side open to receive the wire. The open side is closed by a shutter pivoting on a pivot pin, or coaxial pins, about a mesial distal axis, the shutter being latched in slot closed position to retain the arch wire by a latch having one latch member on the pivot pin / s and a cooperating member on an annular part of the shutter surrounding the pin / s. Preferably the latch members are a mesial distal extending cam shaped recess in the pivot pin / s and a projection protruding from the annular shutter part, or vice versa. The part of the annular shutter part carrying the latch member is made flexible by a mesial distal extending through slot dividing it to form a movable segment of about 200° to 270° of the total circumference; a tool can be inserted into the slot to assist in disengaging the latch. The shutter member can have parts thereof that with the shutter in slot closed position are an interference fit against the device body providing an additional retaining force against opening movement. Preferably the device includes an attitude controlling spring member consisting of a thin sheet metal spring within the body having a free end extending into the arch wire slot to engage an arch wire therein, or alternatively consisting of a flexible extension of the part of the shutter member that closes the slot.

Methods for enhancing ultrasonic reflection imaging are taught utilizing a split-step Fourier propagator in which the reconstruction is based on recursive inward continuation of ultrasonic wavefields in the frequency-space and frequency-wave number domains. The inward continuation within each extrapolation interval consists of two steps. In the first step, a phase-shift term is applied to the data in the frequency-wave number domain for propagation in a reference medium. The second step consists of applying another phase-shift term to data in the frequency-space domain to approximately compensate for ultrasonic scattering effects of heterogeneities within the tissue being imaged (e.g., breast tissue). Results from various data input to the method indicate significant improvements are provided in both image quality and resolution.

Proposed is a system and method for forecasting frequencies associated to future loss and loss distributions for individual risks of a plurality of operating units (30) with at least one measurable liability exposure (31) by means of independently operated liability risk drivers (311-313), and for related automated operation of a loss resolving unit (40) by means of a control unit controller (10). In case of an occurring loss at a loss unit (20, . . . , 26) measure parameters are measured and transmitted to the control unit controller (10). The control unit controller (10) dynamically assigned the measure parameters to the liability risk drivers (311-313) and tunes the operation of the loss resolving unit (40) by resolving the occurred loss by means of the loss resolving unit (40).

An isolation circuitry and method are provided for coupling between a power supply and processing circuitry in order to provide power to the processing circuitry whilst hiding a power consumption characteristic of that processing circuitry. The isolation circuitry comprises a plurality of sub-circuits, with each sub-circuit comprising a capacitor, a first switch configured to provide a first connection between the capacitor and the power supply, a second switch configured to provide a second connection between the capacitor and the processing circuitry, and a third switch configured to provide a third connection across the capacitor to partially discharge the capacitor. Control circuitry controls the plurality of sub-circuits, such that within each sub-circuit the first switch, second switch and third switch are placed in an active state in a repeating sequence. Each of the plurality of sub-circuits further comprises a comparator configured to place the third switch in an open state when a predetermined non-zero voltage difference across the capacitor is reached during the active state of the third switch. By such an approach, it is ensured that the voltage across the comparator at the end of the discharge operation is always the same irrespective of the voltage present at the start of the discharge operation. As a result, the power consumption characteristic of the processing circuitry is entirely hidden by the isolation circuitry. Further, the isolation circuitry of the present invention provides a particular power efficient mechanism for hiding the power consumption characteristic of the processing circuitry.

Where code execution results in an error attributable to multiple data elements, the code is revised so the error results from one element. Where execution improperly functions without error, and the elements contain required but missing properties, the code is improperly functioning in its required-property handling. Errors are organized into classes and error-causing elements are organized into independent sets corresponding to the classes. Elements that are not within any set are determined. Symptom, error, no-error, refined-symptom, and function databases can be employed during code execution analysis. Symptom database entries correspond to elements and indicate errors, or that no errors, are attributable to the elements. Error database entries correspond to elements resulting in errors upon execution. No-error database entries correspond to elements resulting in no errors upon execution. Refined-symptom database entries correspond to root cause elements of errors. Function database entries correspond to root cause elements of no errors.

A networked system of computers, connected dynamically, often very temporarily (e.g. phone call, text, web search), based on individual criteria unique to and controlling each, as they temporarily opt in to the system to evaluate information. All may process data obtained from a database mashed together by combining highly persistent (years) with highly transitory (minutes to weeks) data, temporarily bound thereto. Distributed processing by individual, independent processors is controlled by their own individual criteria, facilitating population, storing, indexing, searching, navigation, querying, and serving of heretofore unwieldy content. Applications execute heretofore impossible procedures as dynamic as situational awareness and personal decisions by their operators. In one example, transitory events can be incorporated by combining persistent data records with temporary ones on a customized site serving an event calendar from a media site, and commercial entities can tap into predictions based thereon.
