  • Patent number: 11097487
    Abstract: An additive manufacturing system includes an additive manufacturing (AM) device, a first sensor device, and a compute device. The AM device is configured to form a bulk component in a layer-by-layer manner, by at least iteratively depositing a first layer of raw material onto a working surface in a deposition chamber, consolidating the initial layer into an initial additive portion of the bulk component, then forming subsequent additive portions of the bulk component by depositing and consolidating a subsequent plurality of layers of the raw material onto the first additive portion. The first sensor device is configured to measure an actual composition of at least one first byproduct portion formed upon consolidation of one of the first or subsequent layers of raw material in the deposition chamber. The compute device includes a processor and a memory, and is communicatively coupled to the additive manufacturing device and first sensor device.

    Abstract: Electrochemical cells, such as those present within flow batteries, can have an electrode and a bipolar plate in at least one half-cell interfacially bonded together with an electrically conductive adhesive. Bonding the bipolar plate to the electrode can decrease contact resistance and sometimes lessen the incidence of parasitic reactions in the electrochemical cell. Flow batteries containing these features can include: a first half-cell containing a first electrode in interfacial contact with a first bipolar plate, a second half-cell containing a second electrode in interfacial contact with a second bipolar plate, and a separator disposed between the first half-cell and the second half-cell. An electrically conductive adhesive interfacially bonds at least one of the first electrode to the first bipolar plate and the second electrode to the second bipolar plate. Each electrode maintains fluid communication with its corresponding bipolar plate.

    Abstract: Microneedle devices are spray coated by nozzles which jet dispense dots onto the individual needles of a microneedle device from a spray nozzle which is angled with respect to the plane of the microneedle device. An angle of between 70° and 45° is preferred and can be achieved by providing the microneedle devices on a support which is inclined at 20° to 45° to the horizontal and using a spray nozzle with a vertical axis.

  • Publication number: 20140326250
    Abstract: A condom comprises, on one or more surfaces thereof, a self-lubricating coating comprising a dry powder having a particle size of 300 microns or less. The self-lubricating coating becomes lubricious when the coating comes into contact with a liquid environment. A method of making a self-lubricating condom comprises providing a dry condom and coating said condom, on one or more surfaces thereof, with a self-lubricating coating comprising a dry powder. The invention also provides the use of a dry powder such as xanthan gum to provide a self-lubricating coating for a condom.

  • Patent number: 8869799
    Abstract: A male contraceptive device includes a condom-like sheath that is placed over the male genital member and has a flavorful formulated solution disposed inside the distal tip. The distal tip is operable to release, eject, or secrete the formulated solution during male ejaculation. The condom-like sheath is shaped to elastically conform to the elongated shape of a male genital member. The sheath has an open proximal end for receiving the male genital member and a distal end that has a distal tip that is selectively closed. The distal tip defines a reservoir containing an ingestible flavored solution and is operable to permit the release of a composition of the flavored solution and any seminal fluid that has entered the reservoir.

  • Publication number: 20140302113
    Abstract: The present disclosure relates to methods for embedded drug molecules into medical catheters, tubes, and other medical devices. The catheter, tube, or other medical device is capable of releasing drugs for extended periods of time. Drugs can be loaded into the wall thereof through diffusion from a loading solution. A counterintuitive approach of using undissolved drug particulates in the loading solution is employed in some embodiments. The drug in the wall of the device and in the loading solution can be in dynamic equilibrium, yielding stable and easy-to-manufacture products. Heat can be used to significantly speed up the drug loading.
