This invention relates generally to footwear such as a shoe, including an athletic shoe, with a shoe sole, including at least one removable midsole section formed by a midsole portion, wherein the removable midsole section is non-orthotic. The removable midsole section is inserted within the shoe upper, the sides of which hold it in position. The shoe sole includes a concavely rounded side or underneath portion, which may be formed in part by the removable midsole section. The removable midsole section may extend the length of the shoe sole or may form only a part of the shoe sole and can incorporate cushioning or structural compartments or components. The removable midsole section provides the capability to permit replacement of midsole material which has degraded or has worn out in order to maintain optimal characteristics of the shoe sole. The shoe sole can, in another embodiment, include at least one compartment containing a fluid, a flow regulator, a pressure sensor to monitor the compartment pressure, and a control system such as a computer processor capable of automatically adjusting the pressure in the compartment(s) in response to the impact of the shoe sole with the ground surface.

A portable universal inhaler system formed from an outer part and an inner part slidably received in the outer part. The inner part defines a compartment for receiving a medication canister and includes a universal connector for making a fluid dispensing connection to a variety of commercially available canisters. The inner and outer parts, when assembled, together form a housing that defines a chamber of sufficient volume to house a metered dose of medication. A mouthpiece or mouthpiece attachment location is provided in fluid communication with the chamber for permitting inhalation of medication from the chamber. The structure of the device makes it compact and portable, in the closed position, allows for storage of a medication canister in operative engagement with the device, and provides a convenient way to dispense medication, using a medication canister and a chamber, for inhalation by a user.

A novel, economical electrical insulation method for the production of ultra-thin insulation layers using a solution coating method. Thin hydrophobic self-assembled bi-functional layers of less than 10 nm thick were deposited by a simple solution method and demonstrated to electrically insulate micro-/nano-devices for in-water detection applications. The insulation layer includes a hydrophobic group which repels water and permits superb insulation properties of the ultra-thin layers. The insulation layer has the additional advantages that it binds to a metal or metal oxide surface and to sensing receptors by covalent bonding using standard silane chemistry.

A method for effecting reduction, stabilization and enhancement of fusion of the human cranio-cervical junction, which may be performed in order to relieve mechanical stresses imparted to the spinal cord and brainstem as a result of an abnormal clivo-axial angle, includes steps of achieving the correct craniocervical relationship, of effecting a fusion of a first portion of a bone forming material based structural member to a human cranium, and effecting fusion of a second portion of the bone forming material based structural member to a least one portion of a human cervical spine. Fusion of the bone forming material based structural member to the human cranium may be promoted through the use an osteointegration apparatus that includes a porous ossomeric mesh and a frame member.
摘要:
A system for making anastomoses between hollow structures by mechanical means is provided with a device in the shape of an annular or tubular element comprising circumferentially provided means, such as pin-shaped elements, for joining the abutting walls of the hollow structures together. An applicator is intended for moving said annular or tubular element in position and activating the joining means thereof, so as to make the anastomosis. Possibly, intraluminal joining means can be inserted without using an annular or tubular element.

A new class of membranes for use in protective clothing. More specifically, the present invention relates to a polymer-polymer membrane with an ionic polymer located within the nanopores of a porous polymer host membrane. A method for making the polymer-polymer membranes involves filling porous polymers with ionic polymers. The porous polymers may be fabricated by a template synthesis which involves sorption. The ionic polymers may be filled in the nanopores of the porous polymer by plasma-induced graft copolymerization of the ionic polymer with the porous polymeric host membrane.
摘要:
Fast kV-switching is a dual energy acquisition technique in computed tomography (CT) in which alternating views correspond to the low and high tube voltages. Its high temporal resolution and its suitability to a variety of source trajectories make it an attractive option for dual energy data acquisition. Its disadvantages include a one-view misregistration between the data for high and low voltages, the potentially poor spectrum separation due to the more-like a sine wave rather than the desired square wave in fast kV-switching, and the higher noise in the low voltage data because of the technical difficulty in swinging the tube current to counter the loss of x-ray production efficiency and loss of penetration at lower tube voltages. Despite the disadvantages, symmetric view matching according to the current invention substantially improves streaks and other artifacts due to the view misregistration, sufficient spectrum separation even in a sinusoidal waveform swinging between 80 kV and 135 kV, and contrast-to-noise for the simulated imaging task maximized at monochromatic energy of 75 keV.
摘要:
Nanoscaled, tunable detector devices for ultrasensitive detection of terahertz (THz) radiation based on the fabrication of one-dimensional (1D) plasma devices having clouds of strongly correlated and spatially confined electronic charge carriers are disclosed. These one-dimensional collective excitations (“plasmons”) are realized using coaxial semiconducting core-shell nanowires or by electrostatically confining a two dimensional charge to one dimension. By exploiting the properties of plasmons confined to reduced dimensions and under a selected device configuration, conventional limitations on carrier drift and transit times that dictate the speed and sensitivity of transistors can be circumvented, and detector sensitivity can be improved. 1D devices with sub-picosecond response times will be important for a range of applications in diverse areas such as remote sensing and imaging, molecular spectroscopy, biotechnology, and in a range of the spectrum that has been difficult to detect. In addition to electromagnetic radiation these devices can be used as detectors of charged particle perturbations.
