Abstract: Method and apparatus for scheduling operations of a network adapter in such a way as to minimize latency in processing received data packets, while still guaranteeing time for processing necessary background tasks. The method includes executing a polling loop in which repeated tests are made for the presence of receive data to process, but only a limited amount of receive data processing is performed before checking for background processing that needs to be performed. The polling loop ensures that immediate attention is given to processing of receive data, without the inherent latency of interrupt processing, but still gives periodic opportunities for background processing. Background processing is performed for a guaranteed minimum processing time before permitting a return to receive processing. Background processing may be performed without a guaranteed minimum processing time, but only when there is currently no receive processing to do.

Abstract: An amplifier comprising an emitter-coupled pair of transistors having inductive load impedances, with capacitive feedback elements tuned with the inductive loads and the capacitive input of the following stage to be resonant at the range of frequencies to be amplified. The reactive loads and feedback elements introduce less noise than with resistive components.

Abstract: A support is provided for supporting a container, such as a plastic trashbag, which is generally incapable of supporting itself in an open, upright position. The support is formed from a unitary, sheet-like blank, which is scored in at least five places to form a series of at least five axially-extending, generally parallel fold lines. The at least five fold lines define at least six panels, including a first panel, a last panel, and at least four intermediate panels. Each of the panels include a top edge, a bottom edge, a first side edge portion, a second side edge portion, an interior surface, and an exterior surface. The at least six panels are hingedly connected along the at least five fold lines to place the at least six panels in a side-by-side relation. Staples are provided for securing the first side edge portion of the first side panel to the second side edge portion of the last panel.

Abstract: 3,5-Diamino-6-(2,3-dichlorophenyl)-1,2,4-triazine isethionate is provided. This salt has high water solubility and thus advantageously allows parenteral administration in the form of a sterile aqueous solution suitable for injection.

Abstract: An adjustable ratio divider comprises a controllable gate connected in series with a divider for passing a clock signal in pulse form whose frequency is to be divided. A means is provided for controlling the gate to subtract a selectable number (including zero) of clock pulses from the clock signal to control the division ratio of the divider.
