Abstract: An assembly of a needle, catheter, and a device for selectively protecting the needle tip from inadvertent needle sticks by an elongate housing having an extending needle and a needle guard adapted for sliding movement relative the housing. The needle guard is formed to carry a catheter hub and catheter, and includes an actuation tab to enable selective sliding movement of the needle guard relative the housing and along the length of the needle. The housing is adapted to be held within one hand to permit insertion of the needle and catheter into a patient, and after insertion, the needle may be withdrawn from the patient and covered by the needle guard by pressing against the actuation tab while slidably retracting the housing and needle relative to the needle guard; upon full retraction of the housing, a detent mechanism formed between the housing and needle guard locks the needle guard about the length of the needle and prevents accidental contact with the needle tip.

Abstract: Individual cells in a memory array are structured and interconnected to permit detection and identification of the locations of errors known as Single Event Upsets (SEUs), with the correction and identification of an affected cell made using only a single parity bit for a group of cells in a memory array, eliminating the necessity for reading an entire memory in order to detect SEUs immediately, and eliminate large numbers of non-useful correction-code cells in order to increase the net useful density of cells in a memory and tolerate a larger rate of SEU events than for previous methods, additionally eliminate the need for purification of packaging materials for memory arrays by removing most radioactive materials and providing a further economic benefit by eliminating the need for organic coatings, which can cause reliability hazards, and to block alpha particles originating in packaging.

Abstract: A dynamic random access memory circuit for storing an information signal using both a data input line and a data output line for a two-transistor dynamic ram cell memory circuit is disclosed. The circuit is incorporated into an integrated circuit array of similar cells. Because of the nature of the circuitry, the data input and output lines of each cell in the array are laid out in parallel, and the data-out line of one random access memory cell becomes the data-in line of the adjacent random access memory cell. Thus, while the addition of a separate line for data-in and data-out adds structure to a single cell, it reduces the overall structure of an array of such cells, and results in a more compact construction of a memory array.

Abstract: A flow control device with an inlet for the flow of fluid and a movable member sealing the inlet and having a flexible body for controlling flow by the extent to which the flexible body of the movable member is buckled.
