Abstract: Apparatus and method of hair depilation for destroying follicle cells is provided where an invasive element, such as a waveguide, probe or needle, is inserted into a hair follicle and pulsed laser energy is radially transmitted through the invasive element to the entire lining of the follicle. The blood vessels of the papilla, the hair shaft, the hair bulge and hair bulb are substantially damaged. The laser employed may be at a wavelength that does not penetrate skin. The laser may pulse laser energy through a frosted tip of a waveguide or probe that scatters the laser radiation radially along a length of the frosted tip to the follicle lining. Otherwise, a protective substances, such as energy absorbing particles, may be used to absorb energy and transmit it to the follicle lining such that there is no damage to the outlying skin. Alternatively, a waveguide may be placed in a needle and the needle inserted into a hair follicle.

Abstract: A system for minimizing co-channel interference between transmission sectors at their common periphery. The system exploits the geographic separation of potentially interfering mobile transmitters and utilizes transmission power control. The system employs sectored antennas in a combined frequency hopping, TDMA system wherein each subscriber in a particular sector is assigned a time slot in the system based upon that subscriber's geographic location within that sector. The transmission power in the sector is reduced during certain predetermined time slots and subscribers who are remote from the fringe of the sector are assigned to these power reduced time slots. During up-link the transmission power for subscribers located proximal to the fringe are reduced to cause less co-channel interference between their signals and the signals from other subscribers in different sectors having the same time slot.

Abstract: Used tires are sorted on-site to separate those which are still good from those that are scrap. At the site, the sidewalls are separated from each scrap tire and the remaining tire portion is slit transversely and laid flat, stacked one atop the other. The stack is transported by vehicle from the site to a central processing facility that shears the tire portions to a uniform width and thickness. The uniformly dimensioned tire portions are then connected into strips by male/female dovetail cuts. Two strips are bonded together at their flat inner tire sides to form a two-ply tread strip. The two-ply tread strips are then used in construction, building component manufacture, fencing or landscaping; the two-ply treads are more flexible then lumber. The sidewalls are used as landfill or grounds cover in landscaping.

Abstract: A method and apparatus for determining skin lesion parameters comprise directing light to the skin in which the lesion is located and monitoring the reflection of that light. Then, the spatial and spectral distribution of the reflected light is analyzed. The depth is determined by finding a location where the difference between a spectral intensity of reflected light and an average reflected intensity is greater than a maximal difference between the intensity of each point and an average intensity for normal skin. The wavelength of the light reflected from the location is determined, and from the wavelength the penetration depth is determined. The penetration depth is also the depth of the lesion below the skin surface. The size is determined by determining a plurality of locations where the deviation between the spectral intensity and the average intensity is greater than the maximal deviation for normal skin. Based on the spatial distribution of the locations the size of the lesion is determined.

Abstract: Varying flow rate and/or the fluid pressure head through a surgical instrument by selecting which of a plurality of fluid lines will supply fluid through the infusion line of the instrument. The fluid lines connect with supply ports of a common connector that has a common discharge port in fluid connection with the infusion line. The fluid lines are each in fluid connection with either a common fluid source, fluid sources at different elevations, or fluid sources at different or the same pressures. Flow control may be based on opening and closing of valves in the flow lines or operating and stopping operation of pumps or vacuum devices. A controller may determine which flow control to implement based on sensing of pressure changes in the eye or on known capacities of the pumps or vacuum devices. The sensing may be effected with a pressure transducer within the eye, but spaced from the infusion and aspiration lines of the surgical instrument.

Abstract: A wheelchair or water closet chair that has arms that may be selectively raised and lowered and a water closet chair that has handgrips that may be selectively raised and lowered. The arms and handgrips have extensions movable towards each other to effect engagement with each other. In addition, each has sensors that sense when the extensions of each are in alignment with each other.

Abstract: A device for dispensing a liquid for inhalation, which comprises an unshielded electrohydrodynamic comminution means (1), a means for supplying a liquid to the comminution means, a sharp discharge electrode (12) and, optionally, a means for charging the discharge electrode to a polarity opposite to that of the comminution means, wherein the discharge electrode is located so as to direct gaseous ions into the body of the comminuted liquid and thereby to fully or partially discharge the comminuted liquid.

Abstract: An apparatus for applying a laser beam to a working surface, by displacing the laser beam to trace a plurality of circular scans over the working surface; and continuously varying the diameters of the circular scans at a rate to produce a substantially homogenous distribution of the laser energy over the working surface.

Abstract: A surgical knife has a blade portion including a sharp edge disposed in a first plane and a dull portion offset from the first plane by a selected amount substantially equal to the amount of desired lengthening. When the blade is inserted into a previously-formed incision in tissue and moved in the direction of desired lengthening, the sharp edge cuts the tissue to lengthen the incision until the dull portion abuts against a wall of the incision to prevent further travel of the blade. The dull portion thus acts as a "stop" which prevents further travel of the blade beyond a desired point, enabling controlled lengthening of the incision.

Abstract: A display package that includes a sheet backing divided into a plurality of sections, each configured to allow the sections to be severed individually or in groups from the rest of the backing and each is arranged relative to each other in rows and columns. Each section holds an item of merchandise, food or medicine within an associated plastic bubble or blister secured to the particular section. The bubbles or blisters are spaced apart from each other. The borders between adjacent sections are removably connected to each other along a relatively narrow region and separated from each other elsewhere by a relatively wide gap.

Abstract: Reconditioning a fiber for laser applications by cleaving off its tip and shaping the cleaved end into a conical or pyramidal shape with a grinder. The cleaved end is grasped in a fiber holder. The grinder is driven, e.g., to rotate. The fiber holder is moved relative to the grinder to bring it into contact with the moving grinder. The fiber holder may be rotated during the contact. Preferably, the axis of symmetry of the fiber is substantially parallel to the plane of rotation of the grinder to effect tangential grinding.
