Title: Electrotransport delivery device
Inventor: MCNICHOLS LARRY A
IPC: A61N1/30
Filed: 1995-11-27
Granted: 2010-03-23
Abstract: An electrotransport delivery device (410) includes control circuitry for discontinuously delivering a beneficial agent (e.g., a drug) through a body surface (e.g., skin 400). For example, the device may be the type which is manually activated by the patient or other medical personnel to activate electrotransport drug delivery. Once electrotransport delivery has been activated, a timer (221) counts a transition interval, typically about one minute, during which the device is allowed to operate and the impedance of the body surface (400) is allowed to stabilize.  Thereafter, the electrotransport current and voltage are then monitored and compared to predetermined limits. Allowing for the transition interval permits tighter tolerances in monitoring the applied current.

Abstract: A target for use with darts, for example, has a base on which a target frame is secured, the frame having a plurality of spaces within each of which is a segment that is movable toward the base when it is struck by a thrown dart.  Corresponding ones of the segments have cavities therein for the accommodation of inserts which are movable independently of the segment toward the target base when such inserts are struck by a thrown dart.  The inserts are so arranged that, together, they form an annulus or ring of individually displaceable components.  Interposed between the target base and the target segments and inserts are switches and a resilient biasing pad which bias the segments to an initial, at rest position.

Abstract: A modular glazing system having several members, each member having one or more keyways or keys that permit the members to be connected. A preferred embodiment has four fundamental shapes: a base longitudinal member (10), an expander (40), an expander (50) and a screen sash member (60). The base longitudinal member (10) has a glazing channel (12) through which supplemental or primary glazing material is inserted. Along one side wall of the base longitudinal member (10) is a keyway (16) formed to interlock with a key (18) from another piece. At right angles to the first keyway (16) in the base longitudinal member (10), and disposed along a bottom wall of the base longitudinal member (10), is another keyway (16), similarly shaped. The base longitudinal member (10) also has an interior aperture (14) through which an L-shaped connector (130) is inserted to form corners. An expander (40) shaped generally like the letter H, has two keys (18), one located on either side of the middle bar of the letter H. An expander (50) has only one key (18), depending downwardly from the middle bar of the letter H. Each expander can be further modified by removing one or more of the walls of the letter H or bending them, as may be required. Glazing material (80) is inserted into the base longitudinal member (10) joined by connectors (130). A resilient material is inserted into the keyways (16) that form the outer edges of each of these base longitudinal members (10), allowing the unit formed to be compression fit into a window opening. Expanders allow several units to be joined.

Title: Buffer overflow and underflow control for facsimile transmission
Inventor: BHASKAR BANGALORE R
IPC: G06F13/38
Filed: 1999-02-24
Granted: 2003-07-15
Abstract: In a facsimile system, buffer underflow is prevented by forcing the transmit pointer to wait at a current end-of-line (EOL) symbol and transmit fill bits until there are at least two EOL symbols stored in the buffer. Buffer overflow is controlled by selectively dropping lines if the write pointer approaches too close to the transmit pointer and the difference between successive lines is sufficiently small (selective line-dropping), dropping lines whenever a permitted maximum buffer size is exceeded, and gradually changing the permitted distance between transmit and write pointers and permitted maximum buffer size as the image is scanned to accomplish a smooth buffer flushing.
