A coal water slurry comprises smaller and larger coal particles. The smaller coal particles are in a range of from about 20 wt % to about 90 wt % of the coal in the coal water slurry and comprise a mean particle size smaller than 25 μm. The larger coal particles are in a range of from about 10 wt % to about 80 wt % of the coal in the coal water slurry and comprise a mean particle size in a range of from 50 μm to 200 μm.

A refrigeration unit and a method for controlling same during start-stop operation is provided. The refrigeration unit may include an engine operable between at least a low engine speed and a high engine speed, a compressor operatively coupled to the engine, and a controller operatively coupled to each of the engine and the compressor. The controller may be configured to operate the engine at a reduced low speed during a delay period, extend the delay period based on the reduced low speed, increase a displacement capacity of the compressor based on the extended delay period, and operate the engine at a reduced high speed.

A control system for a refrigeration unit being powered by a power source and having a compressor, an inverter and an evaporator fan is provided. The control system may include a first switch configured to selectively couple the compressor with one of the power source and the inverter, a second switch configured to selectively couple the evaporator fan with one of the power source and the inverter, and a controller operatively coupled to the first and second switches. The controller may be configured to engage the first and second switches into one of a first state and a second state based on a triggering event. In the first state, the first switch may be configured to couple the compressor with the power source and the second switch may be configured to couple the evaporator fan with the inverter. In the second state, the first switch may be configured to couple the compressor with the inverter and the second switch may be configured to couple the evaporator fan with the power source.

An interlace-to-progressive scan conversion system comprises: a spatial line averaging prefilter; a motion estimator; a three-stage adaptive recursive filter. The motion estimator comprises: a 3-D recursive search sub-component having a bilinear interpolator; a motion correction sub-component having an error-function including penalties related to the difference between a given candidate vector and a plurality of neighboring vectors; a block erosion sub-component. The motion estimator assumes that motion is constant between fields. The three-stage adaptive recursive filter comprises: a first stage that selects between using static pixels data and moving pixels data from a next field; a second stage that selects a more valid set of data between motion compensated data from a previous field and the pixels selected by the first stage; a third stage that combines an intra-field interpolation with the more valid set of data selected by the second stage.

A computer-implemented method of sharing an online shopping cart over a computer network includes the steps of providing an electronic address of a sharee, the sharee being a person with whom the shopping cart is shared. One of a plurality of predetermined roles may be specified for each sharee, each of the plurality of roles defining privileges granted to the sharee. A password may be assigned for the shopping cart and a unique cart number and a unique sharee number may be generated and stored in a database. An electronic message, such as an email, may then be sent to the sharees' electronic addresses, the electronic message including at least the cart number, the cart password and the sharee number. The sharee may then retrieve the saved shopping cart over the computer network by supplying the cart number, the cart password and the sharee number sent in the email. The sharee may then exercise only those privileges defined by the role specified for the sharee. The roles may include, for example, “Read-Only”, in which the privileges granted consist of viewing the shopping cart, “Feedback”, in which the privileges granted consist of viewing and including comments on the shopping cart, and/or “All”, in which the privileges granted include viewing, including comments, changing and canceling the shopping cart.

A friction type resistance booster chain includes a locating structure and a set of chain pieces arranged staggeringly into an upper and a lower row and fitted in the locating structure. Each of two adjacent chain pieces has a force receiving surface being opposite in direction and being able to contact the locating structure. Each of two adjacent chain pieces has a contacting surface therebetween. The contacting surfaces of the adjacent chain pieces contact successively so that the chain pieces can be joined into one integer by means of a corrugated leaf spring or chain plates. The friction type resistance booster chain can be used in numerous fields of clutch, overdrive clutch, brake, speed changer, speed differentiator, tight coupler, overload protector, damper, etc. The friction type resistance booster chain is of simple structure, convenient manufacture, reliable operation, low cost, and it is a brand new elemental component for various machineries.

This invention is related to a deep multi-sensor fusion system for inter-radar interference-free environmental perception comprising of (1) polystatic Multi-Input Multi-Output (MIMO) radars such as radio frequency radar and laser radar; (2) vehicle self-localization and navigation; (3) the Internet of Vehicles (IoV) including Vehicle-to-Vehicle communication (V2V), Vehicle-to-Infrastructure communication (V2I), other communication systems, data center/cloud; (4) passive sensors such as EOIR, and (5) deep multi-sensor fusion algorithms. The self-localization sensors and V2X formulate cooperative sensors. The polystatic MIMO radar on each vehicle utilizes both its own transmitted radar signals and ones from other vehicles to detect obstacles. The transmitted radar signals from other vehicles are not considered as interference or uselessness as conventional radars, but considered as useful signals to formulate a polystatic MIMO radar which can overcome the interference problem and improve the radar performance. This invention can be applied to all kinds of vehicles and robotics.

The present invention proposes a new structure for a high input VRM. This structure is similar to a simple buck converter and can simplify the 48V input VRM design. In this present invention, the interleaved voltage regulator is provided. The interleaved voltage regulator includes an integrated magnetic device for performing both transformer and output choke filter function, a first switch, a second switch, a third switch, and a fourth switch, wherein the integrated magnetic device includes a transformer having a first primary winding, a second primary winding, a first secondary winding, and a second secondary winding, a first choke filter having one end coupled to a first terminal of the first secondary winding, and a second choke filter having one end coupled to a first terminal of the second secondary winding, and the other end of the second choke filter coupled to the other end of the first choke filter to form the output terminal of the isolated voltage regulator. The first switch, the second switch, the first choke filter, and the first secondary winding form a synchronous rectifier circuit. The third switch, the fourth switch, the second choke filter, and the second secondary winding form another synchronous rectifier circuit.
