  • Patent number: 11564694
    Abstract: A smart tourniquet for self-administering a medication is provided. When a patient needs to inject themselves with a medication, intravenously, called an “infusion,” the patient wears the smart tourniquet around their arm and tightens the device. While the patient is using the smart tourniquet, the device automatically records the date and time of the infusion, called a “timestamp”. The patient can also use the device to record the dosage or “number of units” taken at the time of the infusion. The smart tourniquet can store the timestamp as well as other related information as a record. At a later time, the patient can recall prior records on the smart tourniquet itself. The smart tourniquet can also be synchronized with an application and the records can be downloaded for review by the patient, nurse or doctor to render accurate and timely care.

  • Patent number: 7309379
    Abstract: Moving bed adsorber and desorber apparatus and methods, wherein adsorbent material (e.g., beads of resin) moves over a series of vane members and a fluid flow passes between the vane members and through the flowing bed of adsorbent. An adsorbent depth regulator is positioned a spaced distance from the vanes to regulate the depth of the flowing adsorbent bed. In some embodiments, the adsorbent flow may be divided into 2 or more separate streams that pass over 2 or more separate arrays of vane members. Also disclosed are shell and tube desorber apparatus wherein the shell and tube are positioned at certain angle(s) to optimize flow and recovery of contaminant from an adsorbent material and/or wherein vacuum is applied to the adsorbent concurrently with heat to enhance the desorption of contaminant from the adsorbent material.

  • Patent number: 6010444
    Abstract: A method for containing potentially infectious devices. The potentially infectious devices are deposited in a container which contains a monomer, a reducing agent and water. An oxidizing agent is later added to cause polymerization of the monomer to immobilize the devices, and to act as a disinfecting agent due in large part to the exothermic nature of the reaction. In an alternate embodiment, the composition contains a monomer, a thickener and water. Before use, this solution is admixed with an oxidizing and reducing agent and the thickened solution is poured into a container having disposed therein potentially infectious devices. Related methods, kits, devices, and compositions are also disclosed.

  • Patent number: 5972568
    Abstract: A surface wave device is made by forming conductors on a surface of a piezoelectric material in a conductor pattern defined by exposing photoresist via a reticle. The conductor pattern is provided on the reticle in two parts each defining a set of substantially alternate fingers of the pattern, and the photoresist is exposed by two overlaid exposures each via a respective one of the two parts of the conductor pattern. Exposed photoresist can optionally be developed between the two exposures, and conductors can optionally be formed on the surface between the two exposures. The method reduces diffraction limits, permitting manufacture of surface wave devices with sub-micron linewidths for filtering at increased frequencies.

  • Patent number: 5972039
    Abstract: A method for enhancing the absorbency, hand-feel, or both of an article made from fibers having a spin finish thereon, where the spin finish decreases the hand-feel desirability and decreases the absorbency of the article. The method involves subjecting the article to corona treatment for a period of time sufficient to enhance the absorbency, hand-feel, or both of the article. The article produced by subjecting a substrate made of fibers having a finish thereon to corona treatment for a period of time sufficient to enhance the absorbency, hand-feel, or both of the substrate. A method of disposing of such articles by contacting the articles with a hot liquid, such as water, for a period of time sufficient to disperse or dissolve the article. Hot water soluble, cold water insoluble poly(vinyl) alcohol is one suitable fiber material.

  • Patent number: 5896071
    Abstract: A surface wave device comprises first and second SPUDT (single phase unidirectional transducer) resonator filters each comprising first and second transducers, which are preferably RSPUDTs (resonant SPUDTs), the resonator filters being the same except that one transducer of the second resonator filter is a mirror image of the corresponding transducer of the first resonator filter to provide a phase difference of 180.degree.. The surface wave device serves as a balun by having an unbalanced signal connection to the first transducers, and a balanced signal connection comprising signal connections to the second transducer of each of the first and second resonator filters. The resonator filters can be arranged side by side on a common piezoelectric substrate.

  • Patent number: 5891812
    Abstract: An article made from a fabric layer permeable to a first liquid such as water, blood or urine. The article has one side that repels the liquid and another side which absorbs the liquid. The article can be disposed of by heating in a selected liquid, which dissolves or disperses the article. The article may also have a plastic layer affixed thereto to provide additional impermeability. Two of the fabric layers may be affixed with the impermeable sides facing each other to provide an article capable of absorbing fluids from both sides, yet preventing fluids from penetrating from one side to the other. An optional plastic layer may be juxtaposed between the facing sides to provide a further fluid barrier. A method of disposing of such articles comprising contacting the articles with a sufficiently hot second liquid for a sufficient period of time to disperse or dissolve substantially the articles.

  • Patent number: 5835990
    Abstract: A longitudinally coupled double mode surface wave resonator comprises two reflectors, two lateral IDTs (inter-digital transducers), and a centre IDT arranged on a surface of a piezoelectric substrate, for coupling surface waves longitudinally between the IDTs. The two lateral IDTs operate with opposite signal phases by virtue of opposite connections, opposite polarities, or oppositely phased spacings from the centre IDT. Alternatively, or in addition, the centre IDT is divided into two oppositely phased halves. A filter comprising one or more resonators can replace both a filter and a balun in a radio frequency circuit.

  • Patent number: 5821834
    Abstract: A surface wave device filter comprises two 2-pole waveguide coupled double mode resonators (WCRs) electrically connected together in cascade. To permit narrowing of the filter passband for improved out-of-band rejection, e.g. for use of the filter as an intermediate frequency channel filter in a wireless communications system, while maintaining good matching for low ripple in the passband, a shunt capacitance is connected in parallel with the static capacitances of the two WCRs. The shunt capacitance is constituted by interdigital fingers provided on the same piezoelectric substrate as one or both of the WCRs, perpendicularly to the WCR fingers to avoid surface wave interference, conveniently in space otherwise used by rails of the WCRs, optionally with oppositely phased fingers to cancel surface waves generated by these fingers. A capacitance can be similarly provided on the same substrate as any other type of surface wave device.

  • Patent number: 5790000
    Abstract: A cascaded surface wave device filter comprises two 2-pole surface wave device filters connected in cascade. The 2-pole filters each provide a balun function between balanced and unbalanced signal connections, and have either their unbalanced or their balanced signal connections interconnected in the cascade to reduce electromagnetic feedthrough and improve spurious mode suppression. The 2-pole filters are conveniently longitudinally coupled double mode surface wave resonators which are described, or transversely coupled double mode surface wave resonators. Higher order filters can be provided by connecting further 2-pole filters in the cascade. The cascaded filter is particularly useful for filtering at radio and intermediate frequencies in cellular radio equipment.
