摘要:
A bolster structure system possesses anti-decubitus ulcer characteristics, and may cooperate with a mattress overlay also having anti-decubitus ulcer capabilities as part of a mattress overlay system, in which multiple elongate, positionally adjustable, relatively moveable bolsters are configured for selective placement in conditions of lateral under-engagement with the sides of an overlay to create inclined, lateral side elevations of these sides at locations along the length of the overlay. The bolster structure and overlay may each include a dynamic-response core expanse formed of an open-cell, compressible viscoelastic foam coated with an elastomeric, moisture- and gas-flow-managing, differential-thickness coating structure load-transmissively bonded to the entirety of the outside of said core expanse to function as a dynamically-responsive unit therewith.

An elevation structure system possesses anti-decubitus ulcer characteristics, and may cooperate with a mattress overlay also having anti-decubitus ulcer capabilities as part of a mattress overlay system, in which multiple elongate, positionally adjustable, relatively moveable risers are configured for selective placement in conditions of transverse, subposed, under engagement with the sides of an overlay to create substantially non-inclined, elevated, depth-supplemented regions at locations along the length of the overlay. The evelation structure and overlay may each include a dynamic-response core expanse formed of an open-cell, compressible viscoelastic foam coated with elastomeric, moisture- and gas-flow-managing, differential-thickness coating structure load-transmissively bonded to the entirety of the outside of said core expanse to function as a dynamically-responsive unit therewith.

Apparatuses to be worn by users proximate their ankles to manage pressure and swelling, the apparatus including a wrap shaped to conform to a portion of a foot and a lower leg of the user. In some examples, the wrap defines a compressible multiple layer construction including at least one layer that including a compressible foam, a channel sized to receive a portion of the foot and the lower leg, a substantially stretchable flap sized to extend across the channel when the foot and the lower leg are positioned within the channel, a leg portion, and a foot portion, wherein the leg portion may be flexibly angled from the foot portion a bandaged area including the user's ankles. In some examples, the wrap is configured to be fitted around a portion of the user's foot and lower leg to compress at the ankle area to a selected barrier pressure.

Helmet chin-strap harness structure including a pair of bilaterally symmetric, bilaterally equi-flex, non-rigid, fabric-strap-like, substantially mirror-image, flexible lateral elements which define opposite sides for the harness structure, and a bilaterally symmetric chin-strap substructure having laterally opposite sides releasably attachable for fore-and-aft translational sliding on the two lateral elements.
摘要:
A device amplifies light at wavelengths in the vicinity of 1420-1530 nm, using thulium doped silica-based optical fiber. This wavelength band is of interest as it falls in the low-loss optical fiber telecommunications window, and is somewhat shorter in wavelength than the currently standard erbium doped silica fiber amplifier. The device thus extends the band of wavelengths which can be supported for long-distance telecommunications. The additional wavelength band allows the data transmission rate to be substantially increased via wavelength division multiplexing (WDM), with minimal modification to the standard equipment currently used for WDM systems. The host glass is directly compatible with standard silica-based telecommunications fiber. The invention also enables modified silicate based amplifiers and lasers on a variety of alternative transitions. Specifically, an S-band thulium doped fiber amplifier (TDFA) using a true silicate fiber host is described.
摘要:
A multi-information-character, surveillance imaging system and method employing a plural-imager, assembly of surveillance imagers including (a) an optical, daytime, color imager, (b) an optical, nighttime, light-intensified, black-and-white imager, and (c) a thermal imager, and featuring a pair of side-by side adjacent, readily co-viewable, video image display structures. One of these display structures is dedicated to the presentation of thermal imagery, and other is selectively and changeably dedicatable, at any time, to any one alone of the three system imagers. Interconnect structure, including a user-operable controller, operatively and communicatively interconnects the imagers and the display structures in a manner permitting selective user switching of communication between the “other” display structure and one or another of the daytime, nighttime and thermal imagers.

Shock-absorbing, load-cushioning interface structure for use inside, and in operative cooperation with, the shell of a helmet for operative interposition such a shell and the head of a wearer. This structure is characterized with features and performances including (a) compression-deformation-and-slow-return viscoelasticity, (b) non-springy (anti-rebound) during a return from deformation, (c) acceleration-rate(strain-rate)-sensitivity, and (d) a durometer associated with an ILD number which is no less than about 15-ILD.
摘要:
A plural-mode, plural-receptor surveillance imaging system and methodology which offer very simple, versatile one-handed control over the operations and viewing orientations of three different surveillance imagers, thus to minimize the tasks involved in controlling the specific surveillance views which are established and presented by these imagers. Provided for allowing such control are a one-hand-operable, intuitive touch-screen and joystick controller structure, and a appropriate computer for translating user control actions accurately into changes in system behavior. This one-handedness characteristic promotes an operational environment in which the larger share of a user/operator's attention can successfully be focused on the received surveillance imagery, per se, rather than upon details of operating a control.
摘要:
A method of simultaneously encoding successive groups of printed paper sheets or mass distributable material wherein the sheets are provided with unperceptable and virtually invisible common code pattern by laser means which is supplied with a distinct series of coded pulse signals in synchronism with control pulses to produce a different optically-scannable coded hole pattern on each group of printed sheets.
