Abstract: A cooling system for a nuclear reactor control rod drive mechanism (CRDM) includes an evaporation section located within or next to the CRDM and a condensation section fluidly coupled to the evaporation section. The cooling system may include a set of heat fins that extend up from drive coils in the CRDM and heat pipes that extend through the drive coils and heat fins. A fluid evaporates while in the evaporation section of the heat pipes from heat generated by the CRDM and moves out of the evaporation section into the condensation section in the heat fins. The fluid cools and condensates while in the condensation section, recirculating back into the evaporation section. This passive natural circulation cooling system reduces or eliminates the number of water hoses, piping, and other water pumping equipment typically used for cooling CRDM, or the requirement for air cooling, increasing nuclear reactor reliability and simplifying nuclear reactor operation and maintenance.

Abstract: The present disclosure is generally directed to compositions that include antibodies, e.g., monoclonal, chimeric, affinity-matured, humanized antibodies, antibody fragments, etc., that specifically bind a Sortilin protein, e.g., human Sortilin or mammalian Sortilin, and have improved and/or enhanced functional characteristics, and use of such compositions in preventing, reducing risk, or treating an individual in need thereof.

Abstract: A sensor includes an output circuit configured to generate a sensor output signal based on an input signal having a logic high or low level, as may be provided by a Schmitt trigger circuit. During normal operation, the output switches between a first percentage of the supply voltage for logic high and a second percentage of the supply voltage for logic low. To convey a failure at the output, an output signal is output as either ground or the supply voltage when a fault is detected. As such, a fault can be communicated any time the output voltage is not equal to the first percentage or the second percentage of the supply voltage.

Abstract: Embodiments disclosed herein relate to a high frequency connector system with reduced stub lengths that provide improved performance at high frequencies. A first connector includes a plurality of mating contacts designed to electrically connect to a second plurality of mating contacts associated with a second connector. The first connector includes one or more elastic members such that when the second connector is mated to the first connector, the one or more elastic members are compressed between the first and second connectors. The first and second plurality of contacts overlap by a first distance when initially mated, but when the connectors are released, the first elastic member biases the second connector away from the first connector such that the first and second plurality of contacts overlap by a second distance smaller than the first distance.

Abstract: An inhibited non-pregelatinized granular starch suitable for use as a food ingredient in substitution for a chemically modified starch may be prepared by heating a non-pregelatinized granular starch in an alcoholic medium in the presence of a base and/or a salt. Steam treatment may be used to enhance the extent of inhibition.

Abstract: A mechanical keyboard for use on a touch screen comprises an individually and resiliently depressible key and a network of electrical conductors. They key includes a user-facing outer portion and a screen-facing, electrically conductive inner portion, the inner portion being configured to approach the touch screen during depression of the key. The network of electrical conductors is configured to conduct a drive signal to the inner portion of the key, the drive signal being received, during the depression of the key, at a locus of touch screen directly beneath the key.

Abstract: A method for improving visibility of contents displayed on a GUI by providing a dark viewing mode that preserves user-generated formatting and/or style contained in the contents is disclosed. The method includes receiving content for displaying on the display, parsing the received content into one or more objects, based on at least a formatting characteristic of the objects, and comparing for each object a first color characteristic of the object with a second color characteristic to determine if a contrast between the first color characteristic and the second color characteristic satisfies a threshold requirement. Upon determining that the threshold requirement is not satisfied, the method includes adjusting the first characteristic, and displaying the objects with the adjusted first characteristic.

Abstract: In one aspect, data replication processes include setting a minimum snap set creation interval, a maximum snap set creation interval, and a recovery time threshold (RTT). An aspect further includes creating snap sets during a synchronous replication process based on the snap set creation intervals and the RTT. The snap set creation further includes monitoring an amount of data changes since the last snap set creation, monitoring throughput statistics between a source and target system, and estimating an amount of time to replicate the data changes to the target system based on the data changes and throughput statistics. Upon determining the time to replicate the data changes reaches the RTT and the time since the last snap set creation passes the minimum interval, the snap set creation includes creating a next snap set, storing the next snap set at the source, and replicating the next snap set at the target.

Abstract: Embodiments for automatically distributing phone call recordings to interested parties generally include associating one or more forwarding criteria with each of one or more interested parties, establishing a phone call from a calling party to a destination number through an institutional phone system, recording the phone call, and, if the phone call satisfies one or more forwarding criteria associated with one or more interested parties, automatically distributing the recording of the phone call to the at least one interested party associated with the satisfied one or more forwarding criteria. Distribution may be by e-mail, by uploading the recording to a website that interested parties (and preferably only interested parties) can access, by queuing the recordings for export to physical media, and/or through a voice mail system. Calls may be selected for distribution based on the caller, the called party, conversation content, call time, or any other suitable criteria.
