Abstract: Described are memory modules that support different error detection and correction (EDC) schemes in both single- and multiple-module memory systems. The memory modules are width configurable and support the different EDC schemes for relatively wide and narrow module data widths. Data buffers on the modules support the half-width and full-width modes, and also support time-division-multiplexing to access additional memory components on each module in support of enhanced EDC.

Abstract: A drug storage and dispensing system that includes a packaging unit and an injection device for pre-filled containers having a needle shield and containing a medication is disclosed. The drug storage and dispensing system of the present disclosure provides for drug administration while minimizing the space occupied by such containers in the cold chain. The packaging unit minimizes the risk of a needle-stick injury, as a healthcare worker does not have to manually remove the needle shield. The injection device provides a novel way of auto-disabling a container, such as a syringe, as a plunger rod is not engaged with the container until the container is actually used. The drug storage and dispensing system provides for a reduction in the number of steps required to perform an injection, and thus a productivity and efficiency gain in mass immunization campaigns.

Abstract: A coffee bean shaving process is utilized herein to produce shaved coffee bean products, such as coffee flakes, coffee shavings, and coffee slices, which may comprise clean and smooth faces and rough edges. Due to the shaving process described herein, the shaved coffee bean products may be produced with larger and fewer surfaces, thereby yielding a coffee product with greater surface area to volume (SA/V) ratios, particularly when compared to coffee grounds produced by conventional burr grinders. Consequently, by optimizing these SA/V ratios, it has been observed that one can maximize the coffee making potential of a coffee bean and reduce the SA/V variances between particles, thereby creating more consistent results.

Abstract: A method synchronizes clock signals generated by a system that includes multiple PLLs that are connected in parallel and output frequency dividers driven by the PLLs. The system receives a common frequency reference signal and a common synchronization signal. Each PLL may have a reference signal frequency divider. The reference frequency divider may be phase-reset, for example, by a transition to a first logic state in the synchronization signal, and the output frequency dividers are each phase-reset, for example, by a transition to a second logic state following the transition to the first logic state in the synchronization signal. The transition to the first logic state may be, for example, a rising edge.
