    • A disposable cover for an elongated probe of a portable thermometry apparatus includes an open proximal end and a distal tip sized to fit over at least an axial portion of the elongated probe. The cover includes a transitional wall thickness at its proximal end for fitting over a holding barb of said probe, the transitional wall thickness varying between a first wall thickness adjacent the proximal end and a second wall thickness that is substantially thinner than the first wall thickness at a distal axial distance relative to the proximal end. The second wall thickness defines a weakened wall portion which is ruptured when the cover has been ejected from said holding barb by an ejection mechanism of the thermometry apparatus. The cover can also include a thinned walled portion over at least a portion of the distal tip and can also include a feature that permits the user to detect when a cover has been attached to a probe.
    • 用于便携式温度测量装置的细长探针的一次性盖包括敞开的近端和尺寸适合于细长探针的至少一个轴向部分的远端。 所述盖在其近端处包括过渡壁厚,用于装配在所述探针的保持倒钩上,过渡壁厚度在邻近近端的第一壁厚度和基本上比第一壁厚度薄的第二壁厚度之间变化 相对于近端的远端轴向距离。 第二壁厚限定了当盖已经通过温度测量装置的弹出机构从所述保持倒钩中弹出时被破坏的弱壁部分。 盖子还可以包括在远端尖端的至少一部分上的变薄的壁部分,并且还可以包括允许使用者检测何时盖子已经附接到探针的特征。

    • A microwave handheld radiometer for measuring subsurface tissue temperature of a subject includes a microwave antenna disposed relative to a handheld radiometer housing and adapted to electromagnetically couple to a skin surface of a subject, a circulator having a first circulator input and a second circulator input, wherein the first circulator input is electrically coupled to said antenna via a microwave feedline. A switch is electrically disposed between the antenna and an microwave feedline, said switch having a calibrate state and a measure state. A noise source, electrically coupled to the circulator, is being configured to provide a first source of thermal noise at a first temperature and a second source of thermal noise at a second temperature, wherein the noise source is switched between the first source and second source upon external command wherein a detector provides an output wherein surface temperature effects are corrected for the sub-surface measurement.
    • 用于测量受试者的地下组织温度的微波手持式辐射计包括相对于手持式辐射计壳体布置并适于电磁耦合到受试者的皮肤表面的微波天线,具有第一循环器输入和第二循环器输入的循环器,其中 第一循环器输入通过微波馈线电耦合到所述天线。 开关电气地设置在天线和微波馈线之间,所述开关具有校准状态和测量状态。 电耦合到环行器的噪声源被配置成在第二温度下在第一温度和第二热噪声源处提供第一热噪声源,其中噪声源在第一源极和第二源之间切换 根据外部命令,其中检测器提供输出,其中对于子表面测量校正表面温度效应。
