Abstract: Image quality is assessed for a digital image that is a composite of tiles or other image segments, especially focus accuracy for a microscopic pathology sample. An algorithm or combination of algorithms correlated to image quality is applied to pixel data at margins where adjacent image segments overlap and thus contain the same content in separately acquired images. The margins may be edges merged to join the image segments smoothly into a composite image, and typically occur on four sides of the image segments. The two versions of the same image content at each margin are processed by the quality algorithm, producing two assessment values. A sign and difference value are compared with other image segments, including by subsets selected for the orientation of the margins on sides on the image segments. The differences are mapped to displays. Selection criteria determine segments to be re-acquired.

Abstract: An extension for a bit or cutter tool relative to a rotational power source. The extension includes a blind bore receiving the shank of the bit or cutter. The opposite end of the body has structure that can be operatively connected to the source of rotational power. A second bore through the side of the body intersects the first bore. The second bore has two portions. The inner-most portion has a smaller diameter and is internally threaded. The outer portion has a larger diameter and slidably receives a clamping member. Clamping member can be retained by a shoulder bolt and has an end that can enter into the blind bore to clamp the shank in place. Preferably the clamping member is a sleeve having a center bore and a concentric exterior. Another aspect of the invention includes a biasing means that biases the sleeve outward of the bore.

Abstract: Electrical components projecting outwardly from the storage tank portion of an electric water heater are shielded from foam insulation material being injected into an insulation space between the tank and an outer jacket portion of the water heater by a hollow, open sided foam dam structure extending through a jacket opening and circumscribing the electrical components. Force exerting projections on the dam engage the interior side surface of the jacket and forcibly hold the inner side of the dam structure in sealing engagement with the tank. The projections also hold an outer side peripheral lip of the dam in a an outwardly and resiliently deflected orientation in which it is sealingly pressed inwardly against the outer side surface of the jacket around the periphery of the opening therein to prevent injected foam from being forced outwardly through the jacket opening.

Abstract: A foam dam in the insulation cavity of an electric water heater comprises a plastic bag into which liquid foam insulation is injected, the bag having an essentially closed top edge portion with only a small opening for receiving the injected insulation. A small portion of the insulation injected into the bag is forced outwardly therefrom via small metering holes to form external protrusions on the bag that mechanically interlock with a second batch of insulation subsequently injected into the cavity and prevent the hardened second insulation batch from pulling away from the bag. The substantially closed top edge of the bag permits the insulation injected into the bag to pack therein and increase the top-to-bottom hardened foam density uniformity. Side edges of the bag may be pleated to increase the sealing area of the foam dam.

The index signal indicates a specific n-bit sample, the specific n-bit sample being one of a sequence of n-bit samples corresponding to the Haar transform. The inverse transform logic is coupled to the index signal.

Abstract: A water heater is provided with a specially designed molded bottom pad/foam dam member formed from a crushable material, such as polystyrene, which is received in a metal bottom pan and has concentric circular grooves formed in its top side to receive circular bottom end edge portions of the tank and outer jacket portions of the water heater. A circumferentially spaced plurality of rigid support members are imbedded in the bottom pad/foam dam member and underlie its tank groove to prevent the tank from crushing the member one of the support members is formed from an electrically conductive material and defines an electrical grounding path between the tank and the bottom pan, and the other support members are formed from a thermally insulative material to inhibit heat loss from the tank to the bottom pan.

Abstract: An apparatus and method are provided for synthesizing a variable frequency sinusoidal waveform. The apparatus and method exploit octant symmetry properties of sine and cosine waveforms, when taken together. The digital frequency synthesis apparatus includes a phase signal and a phase-to-amplitude converter. The phase signal indicates a desired phase angle of the sinusoidal waveform. The phase-to-amplitude converter is coupled to the phase signal. The phase-to-amplitude converter provides a desired amplitude sample corresponding to the desired phase angle, where the desired amplitude sample is derived from amplitude samples corresponding to an octant of the sinusoidal waveform. The phase-to-amplitude converter includes a Haar Transform-based coarse octant amplitude sample generator that computes Haar coefficients corresponding to the phase signal and transforms the Haar coefficients into the desired amplitude sample.

Abstract: An electric water heater has upper and lower electric resistance type heating elements respectively controlled by a single pole, double throw upper thermostat and a single pole, single throw lower thermostat. The upper and lower thermostats are operatively interconnected by a wiring harness having outer wire end portions that may be connected in various orientations to the terminal block portion of an external junction box to provide the water heater with a variety of heating element operating modes without having to replace either of the thermostats or vary the wiring harness interconnections therebetween. The water heater may thus be advantageously manufactured in a single variant that may be easily and quickly modified in the field to selectively alter the heating element control mode of the water heater.

Abstract: An electric water heater is provided with simplified phase conversion apparatus including a terminal structure having replaceable line lug portions which are wired to a single phase row of multi-pin connector sockets by single phase routing circuitry, and to a three phase row of multi-pin connector sockets by three phase routing circuitry. Electrical supply wires from sets of fuse holders connected to multiple thermostat/heating element sets are grouped and connected to associated multi-pin connector plugs. To ready the water heater for single phase operation, the plugs are connected to the single phase row of sockets, and to convert the water heater to three phase operation the plugs are simply disconnected from the single phase sockets and connected to the three phase sockets. In this manner the necessity of individually repositioning all of the fuse holder wires on the terminal structure to change from single to three phase operation, or vice versa, is eliminated.
