    • Presented is a fecal/urine management system that includes a mattress having an aperture (e.g., catchment aperture) disposed through its top surface. The catchment aperture allows positioning a patient's anus over the aperture when the patient is positioned on the mattress. Accordingly, bodily waste may be collected in the aperture and thus separated from the skin of the patient. To prevent soiling the mattress, a catchment insert is positioned within the catchment aperture. The catchment insert, in one embodiment, includes an annular platform that rests on the top surface of the mattress and catchment bag that is adapted to be positioned within the mattress aperture. The catchment bag and annular platform prevent most or all bodily waste from contacting the mattress. Further, the catchment bag is adapted for removal through the top surface of the mattress with little or no movement of the patient.
    • 提出了一种粪便/尿液管理系统,其包括具有通过其顶表面设置的孔(例如,集水孔)的床垫。 当患者定位在床垫上时,集流孔允许将患者的肛门定位在孔上。 因此,身体废物可以被收集在孔中并且因此与患者的皮肤分离。 为了防止弄脏床垫,集水口插入物位于集水口内。 在一个实施例中,集水插入件包括环形平台,该环形平台放置在适于定位在床垫孔内的床垫和集水袋的顶表面上。 集水袋和环形平台可防止大部分或全部身体废物接触床垫。 此外,流出袋适于通过患者的很少或不移动而移除床垫的顶表面。

    • Methods of making cross sectional, functionally-graded munitions propellants exhibiting various distributions of particle concentrations and burn rate, including having a fast burning core and slower burning outer layer(s). Unlike prior art methods of preparing such munitions, propellants prepared according to our inventive method(s) may be performed substantially as a single extrusion step or as a few processing steps, without requiring the time, expense and/or difficulties that characterized familiar, laminating methods and methods which use multiple extruders. Our inventive method advantageously employs a demixing phenomenon that, prior to our inventive application and teaching, has been considered quite undesirable in the preparation of propellants where uniformity and well-mixedness have been propellant attributes widely sought after.
    • 具有表现出各种分布的颗粒浓度和燃烧速率的横截面功能分级弹药推进剂的方法,包括具有快速燃烧芯和较慢燃烧的外层。 与现有技术的制备这种弹药的方法不同,根据我们的发明方法制备的推进剂可以基本上作为单个挤出步骤或几个加工步骤进行,而不需要熟悉的层压的时间,费用和/或困难 使用多个挤出机的方法和方法。 我们的创造性方法有利地采用了在我们的发明应用和教学之前,在制备其中均匀性和良好混合性已经被广泛追求的推进剂属性的推进剂的非常不合需要的分层现象。

    • A multi-component three dimensional energetic device and the method of maacturing it. The method includes the steps of forming a quantity of an energetic material into a plurality of sheets having relatively no appreciable thickness, and then cutting at least one required shape from the surface of a portion of each of the plurality of sheets to define an opening for at least one inlay of a different material. An inlay of the different material is placed in the openings to form a plurality of stackable shapes that are then bonded together to form the multi-component three dimensional energetic device. The preferred embodiment includes forming the inlay from an energetic material that is different from the sheet energetic material. Optionally a bonding agent may be admixed with at least one of the materials to facilitate bonding to form the device. The bonding agent may or may not be an energetic material, as desired. The required shape are preferably cut along three axes of cutting to approximate non axial shapes without substantial step-like deviation from the desired shape.
    • 一种多组分三维能量装置及其制造方法。 该方法包括以下步骤:将一定数量的能量材料形成为具有相对不明显厚度的多个片材,然后从多个片材的每个片材的一部分的表面切割至少一个所需形状,以限定用于 至少一种不同材料的嵌体。 将不同材料的嵌体放置在开口中以形成多个可堆叠的形状,然后将其结合在一起以形成多组分三维能量装置。 优选实施例包括从与片材高能材料不同的高能材料形成嵌体。 任选地,粘合剂可以与至少一种材料混合以便于粘合以形成该装置。 根据需要,粘合剂可以是或可以不是能量的材料。 所需的形状优选地沿着三个切割轴切割,以近似非轴向形状,而没有与期望形状的实质的阶梯状偏离。
