Abstract: The disclosed technology generally relates to electrical overstress protection devices, and more particularly to electrical overstress monitoring devices for detecting electrical overstress events in semiconductor devices. In one aspect, an electrical overstress monitor and/or protection device includes a two different conductive structures configured to electrically are in response to an EOS event and a sensing circuit configured to detect a change in a physical property of the two conductive structures caused by the EOS event.

Abstract: A spraying apparatus for simultaneously dislodging insects from a plant's leaves and cleaning the plant includes a tubular handle portion having a bend point and being connected to a substantially straight tubular main body portion. A nozzle portion at a distal end of the main body is adapted to create a substantially planar wall of water around the nozzle portion when the apparatus is connected to a source of water under pressure. In operation, a user holds the handle so that the main body is substantially horizontal and advances the nozzle into and out of the plant at a plurality of locations. The wall of water is directed in all directions and dislodges insects from the top and bottom sides of infested leaves. Additionally, the wall of water dislodges dirt and insect waste and directs it downwardly off of the plant with the flowing wall of water. The bent handle enables the user to treat the plant at varying locations without excessive bending and craning.

Abstract: In-line roller skates capable of riding at high speed on a skating surface and of being braked by the skater without the need for braking pads or similar expedients for this purpose. Each skate is provided with a set of composite wheels supported for rotation in tandem on a frame secured to the underside of a boot. Each composite wheel includes a central section, a substantial portion of which is formed of a synthetic plastic material exhibiting a low coefficient of sliding friction having a slippery outer surface, the central section being flanked by side sections formed of a synthetic plastic material exhibiting a higher coefficient of sliding friction providing a slip-resistant outer surface.

Abstract: In-line roller skates whose wheels make it possible for a skater to stop without the need for a braking pad or other special expedients for this purpose. Each skate includes a boot to accommodate the skater's foot and a frame secured to the underside of the boot supporting a series of in-line wheels having a composite structure. Each composite wheel includes a center section formed of hard material, such as high-density polyethylene, having a low coefficient of friction, the center section being flanked by side sections formed of relatively soft material, such as cast polyurethane, having a high coefficient of friction. In order to stop or reduce speed, the skater turns the in-line skates away from the direction of travel as he would when braking ice skates. This maneuver causes a portion both of the hard and a soft section of the composite wheels, now angled with respect to the direction of travel, to frictionally engage the ground to effect a braking action.

Abstract: A scanning arrangement for an infra-red imaging device in which a column of I.R. detectors, and similarly a column of L.E.D.'s, scans a field broadside to produce a band of parallel line scans, a number of such band scans being provided to cover the field. Each band scan is performed by a respective mirror facet of a rotating polygonal drum, the facets being tilted at slightly different angles to provide the band displacement. Non-uniformity of the column of I.R. detectors or the L.E.D.'s or the interconnecting channels tends to produce the same pattern of non-uniformity within each band. This is overcome according to the invention by periodically tilting the drum by a random fraction of a band-width so that on successive occasions a particular element of the field is processed by different detector/L.E.D. channels.
