Abstract: An additive manufacturing apparatus includes a feed module and a take-up module that are configured to operably couple with a foil. A stage is configured to hold one or more cured layers of a resin that form a component. A radiant energy device is positioned opposite to the at least one stage. The radiant energy device is operable to generate and project radiant energy in a predetermined pattern. An actuator is configured to change a relative position of the at least one stage and the foil. An accumulator is positioned between the feed module and the take-up module. The accumulator is configured to retain an intermediate portion of the foil to allow a first portion of the foil upstream of the accumulator to move at a first speed and a second portion of the foil downstream of the accumulator to move at a second speed during a defined time period.

Abstract: A driver for driving a switched-mode power supply is presented. The driver receives a set of input signals. Each input signal is configured for changing a state of an associated power switch from a first state to a second state. The driver generates an output signal to change the state of the associated power switch from the first state to the second state. When the first state is an on state and the second state is an off state, the driver asserts the output signal to change the state of the associated power switch to perform an on-off transition. When the first state is the off state and the second state is the on state, the driver delays the assertion of the output signal to perform an off-on transition by a predetermined delay time, so that the off-on transition is delayed until all intended on-off transitions have occurred.

Abstract: An instrumentation amplifier with an electronically adjustable gain is disclosed. The gain is adjusted by electronically controlling a resistance coupled to a feedback portion of the instrumentation amplifier. The resistance is adjusted by switches controlled by resistor-control signals references to a common mode voltage appearing at the input of the instrumentation amplifier. Accordingly, the instrumentation amplifier is capable of accommodating a high voltage range of common mode voltages while still providing controllable gain.

Abstract: A multi-functional jetting tool can be installed within a tubular work string, or attached to the distal or leading end of the tubular work string, in order to facilitate improved cleaning of downhole and/or subsea equipment—and particularly equipment with internal recesses, cavities or crevasses. A bull nose cap member, which can be constructed of plastic or other non-abrasive material, can be attached when the jetting tool is run on the distal end of a tubular work string. Fluid jetting ports can be selectively equipped with standard-sized or adjustable nozzles, thereby permitting customized fluid jet flow pattern from the jetting tool along the tool body in multiple directions for desired applications.

Abstract: A method for chemically stabilizing polishing slurries in aqueous suspension to prevent their agglomeration while maintaining their surface activity is disclosed. The method prevents the formation of irreversible particle agglomerates during drying and permits the subsequent re-suspension of dried particles with no impact on the particle size distribution. The stabilization method can be customized based on knowledge of the colloid surface charge at suspension pH conditions, addition of a charged species having like charge to the colloid at the suspension conditions, and control of the concentrations of the charged species and other ions in suspension.

Abstract: A no-laxation bulking system and a method for preparation of same is disclosed. Gelatin and pectin are combined to fro a dry-blended mixture. A second set of ingredients comprising modified polydextrose and erithritol is then blended to form a first liquid mixture. A second liquid mixture comprising at least one acid and water is formed. The dry-blended mixture is added to the first liquid mixture, forming a first combination. Water is added to the first combination, and the resultant combination is heated to a first predetermined temperature. The first predetermined temperature is maintained for a predetermined time period, and the heat is reduced to a second predetermined temperature. The second liquid mixture is added to the combination. Other embodiments comprise adding hydrogenated starch hydrolysate (HSH) and/or active ingredients. The second liquid mixture also may preferably include fruit concentrate, flavor, color and/or sucralose.

Abstract: A method and system for identifying clusters of similarly-configured computers. The method, for example, comprises gathering system and business configuration information values from a set of computers. Next, at least a portion of the system and business configuration information values gathered from the set of computers is analyzed along with the numbers of computers that are configured in various ways. Then, using the result of the analysis as a guide, logical expressions of configuration information values are selected for use as definitions of one or more clusters of similarly-configured computers, the selection process generally maximizing the number of computers included within each cluster and also generally maximizing the number of configuration information value specifications included within the definition of each cluster.

Abstract: A battery backup system has a number of batteries and number of switches interconnecting the batteries to either a high-power load or a low-power load. The batteries are selectively connected in series with each other, or in parallel with each other by the switches. When the batteries are in the parallel configuration they are also connected to power the low-power load, and when in series, to power the high-power load. Between switching from the high-power series configuration to the low-power parallel configuration, a transition phase is provided during which a transition battery powers the low-power load.
