摘要:
A catheter support comprising a pliant tubular structure of rigidity greater than the penis including a region surrounding the penis shaft, a region surrounding the penis head, and a substantially closed end having an aperture aligned with the penis terminal opening through which the catheter is received. The catheter support limits or eliminates catheter movement substantially radial to the axis of the catheter and thus radially against the inner opening if the penis head, substantially reducing or eliminating abrasion or other insult to the penis surfaces and tissue that interface with the catheter. One embodiment comprises 2 substantially identical elongated halves having longitudinal recesses and hinged together to close around the penis end and catheter providing the catheter support in a structure having improved comfort and wearability.

A new extended coverage anti-G suit combines a new continuous lower body pressure bladder with a nonextensible outer covering. The continuous lower body pressure bladder includes an abdominal bladder section and a pair of wrap-around leg bladder sections. Each leg bladder sections overlaps slightly at the inseam. A trouser-shaped nonextensible outer covering covers the pressure bladder and restrains its expansion when the pressure bladder is inflated. A pair of pressure socks worn between regular socks and boots interconnects with the pressure bladder.

A grouting cartridge is described for placing in a hole of a support structure. The cartridge is capable of rapidly forming a solid grout about an anchor element where the anchor element is thrust into the hole. The cartridge comprises a frangible outer tubular casing fabricated of plastic or the like and containing a uniform mixture of a water-hardenable cement and a multitude of frangible microcapsules which hold droplets of water. One or more of these cartridges is placed in the borehole, and the anchor element in a one-step operation is inserted therein, and preferably rotated, to pierce the casing and rupture the microcapsules to uniformly wet the cement to form a cement paste. The cement paste under the pressure of the anchor element flows into intimate contact with the hole wall of the support structure and into intimate contact with the surfaces of the anchor element. The cement paste rapidly solidifies forming a solid grout between the support structure and the anchor element to affix the anchor element securely to the support structure.

The azimuth beamspread smear effect in a radar image is simulated by convoluting a terrain function with an antenna gain function for each sweep that the target object is within the antenna gain bandwidth. The initial grid map of elevation-reflectance terrain data is combined with aircraft position and antenna orientation data to provide composite terrain data required to compute a terrain function along each range arc. Each radar sweep generates a data raster of composite terrain data for the R range points within that sweep. The antenna bandwidth is a small sector, M sweeps wide, which moves across the scanned sector as the antenna rotates forming R range arcs. A constantly changing block of composite terrain data for the M sweeps and R points must be continuously maintained to generate the beamspread smear by convolution of the terrain function and the antenna function. The MxR block of terrain data is held in the form of a Fourier series for each range arc. Each range arc Fourier series requires a (2N+1) memory capacity (N sine terms, plus N cosine terms, plus one constant term). The total memory requirement for the MxR data block in Fourier series form is (2N+ 1)R. The terrain Fourier series for each point along the target range arc is multiplied by the antenna gain at that point (also expressed as a Fourier series) to provide the terrain-gain point product, or return signal power for that point. The terrain function Fourier series constantly changes as the antenna rotates, and is generated from the composite terrain data through an updating technique in which a new leading sweep is added to the MxR block and the previous trailing sweep is dropped. The antenna gain pattern is typically symmetrical and has a Fourier series with N term plus a constant. The antenna function is fixed for each antenna model, mode and operating circumstance.

Input data from an XY encoder stage is continuously monitored and compared to an internally generated count as the stage is adjusted in position. The internal count is generated a single count at a time by transitions in the X-Y input data on the basis that each transition is a one-step change in encoder position. A series of one-step transitions causes both the input data and the internal count to change together, or track. If a single transition is greater than a single encoder step, the input data advances ahead of the internal count and tracking is lost, causing a comparison error. The error halts the monitoring process, activates an alarm, and holds the current input data and internal count for visual comparison in a numerical display. The operator can then remonitor the faulty portion of the stage encoder to determine the nature of the error. The transition monitor is provided with internal testing circuit for counting up and down, changing counting directions, and detecting a prewired multistep test error.

A laminated roofing material includes an aluminum foil top sheet laminated to a polyethylene film by an ionomer resin. After the sheets are bonded together they are cooled to set the resin and a asphalt coating is applied to the exposed polyethylene sheet and covered with a release paper. The roofing material is applied over an underlayment to form a roof supported by conventional sheeting material.
