Abstract: Apparatuses and methods related to port arbitration of a memory system are described. A memory system can receive a first number of transactions and a second transaction from a first traffic stream and a third number of transactions and a fourth transaction from a second traffic stream. The memory system can process the first number of transactions at least partially concurrently with the third number of transactions. Responsive to a total quantity of transactions of the first number of transactions and the second transaction being at least a threshold quantity of transactions, the second transaction can be processed by the memory system and, subsequent to processing the second transaction, the fourth transaction can be processed by the memory system.

Abstract: In an embodiment, a processor includes at least one core having one or more execution units, a first cache memory and a first cache control logic. The first cache control logic may be configured to generate a first prefetch request to prefetch first data, where this request is to be aborted if the first data is not present in a second cache memory coupled to the first cache memory. Other embodiments are described and claimed.

Abstract: The present invention is an apparatus used to launch a tire deflation device into the path of a fleeing vehicle. The present invention makes use of a guide frame to support and guide the tire deflation device towards the intended destination. The energy storing mechanism stores the energy required to launch the tire deflation device. The push train delivers the energy to the tire deflation device. The launching of the tire deflation device is triggered by a wireless remote system, otherwise known as the wireless trigger mechanism.

Abstract: A compact slide spinner is disclosed. In the preferred embodiment, the compact slide spinner is used to prepare smears for microscopic evaluation. The spinner incorporates a disposable or reusable slide holder which encases a portion of a slide onto which the material to be smeared is placed. The holder containing the slide is then accelerated by spinning. Specimen fluid not adhering to the slide is contained within the slide holder which is discarded following preparation of the smear. Using this low-cost device, a uniform quality smear is quickly and easily prepared, while reducing the risk that laboratory personnel will be exposed to aerosol borne contagions.

Abstract: Compositions for preparing cocoa beverages are prepared by mixing cocoa powder, non-fat milk solids, malto-dextrin, an emulsifier and an artificial sweetener to make a mixture which then is ground to disperse the emulsifier and to reduce lumps. The ground mixture then is agglomerated and after a resting period of up to 120 seconds, the agglomerates are dried.

Abstract: An aid to tuning musical instruments. A microprocessor-controlled frequency standard is used to control a shift-register whose data is the digitized sound detected by a microphone. The data from the shift register are loaded into a parallel-load latch and then used to control an array of indicator lights. The pattern in the lights indicates the error in pitch of the sounded note. A person tunes a musical instrument by making the pattern in the lights become nearly stationary. The same synthesized frequency is made available in a speaker.

Abstract: A disk shaped cassette for centrifugal fluid separation, particularly blood separation, and a drive system for high speed rotation of the cassette. The cassette is driven at speeds which permit very rapid separation of the blood in times on the order of seven (7) to twenty (20) seconds by an automated control. The cassette is supported by a flexible support coupling and mounting system that permits the entire rotating mass to spin about the center of mass unique to the particular cassette as filled. The cassette typically includes a peripheral collection chamber which may be either annular, lobed or channel shaped. A cassette enabled to hold plural separation tubes is also shown. A gel can be placed in the cassette with a density between the fluid components to be separated and after centrifuging maintains the component separation that centrifuging creates.

Abstract: A fluorometric titrator has means to transfer a pipette between first and second positions and a buret for a chelating agent has a reversible drive powered either by a pulse generator or an oscillator. Valve controlled means are operable to place the buret in communication with the pipette or a reservoir. In the first position of the pipette, a precise sample volume is aspirated into it by the buret, then driven by the oscillator and in its second position and with the buret drive reversed but still powered by the oscillator, the sample volume is discharged from the pipette into a cuvette in the fluorometer. On the resulting fluorescence the fluorometer output drives the pulse generator to dispense chelating agent and to operate a counter until a selected end point is reached. The pipette is then returned to its second position with the buret drive again operated by the oscillator and during the return, the buret is refilled.
