    • A mobile, miniature x-ray source includes a low-power consumption cathode element for mobility, and an anode optic creating a field free region to prolong the life of the cathode element. An electric field is applied to an anode and a cathode that are disposed on opposite sides of an evacuated tube. The anode includes a target material to produce x-rays in response to impact of electrons. The cathode includes a cathode element to produce electrons that are accelerated towards the anode in response to the electric field between the anode and the cathode. The tube can have a length less than approximately 3 inches, and a diameter or width less than approximately 1 inch. The cathode element can include a low-power consumption cathode element with a low power consumption less than approximately 1 watt. The power source can include a battery power source. A field-free region can be positioned at the anode to resist positive ion acceleration back towards the cathode element. An anode tube can be disposed at the anode between the anode and the cathode, and electrically coupled to the anode so that the anode and the anode tube have the same electrical potential, to form the field-free region.
    • 移动的微型x射线源包括用于移动性的低功耗阴极元件和产生无场区域的阳极光学器件,以延长阴极元件的寿命。 电场施加到设置在真空管的相对侧上的阳极和阴极。 阳极包括响应于电子的冲击而产生x射线的靶材料。 阴极包括阴极元件,以产生响应于阳极和阴极之间的电场而朝向阳极加速的电子。 该管可以具有小于约3英寸的长度,以及小于约1英寸的直径或宽度。 阴极元件可以包括具有低于约1瓦特的低功耗的低功耗阴极元件。 电源可以包括电池电源。 无场区域可以位于阳极处以抵抗朝向阴极元件的正离子加速。 阳极管可以设置在阳极和阴极之间的阳极处,并且电耦合到阳极,使得阳极和阳极管具有相同的电势,以形成无场区域。

    • An apparatus for programming a fuse includes a programmable branch comprising a fusable element and a reverse-biased diode connected in series. The programmable branch is connected in parallel with a current boost capacitor. An electrical source or input supplies a current that is sufficient to charge the current boost capacitor to a breakdown voltage of the reverse-biased diode and subsequently melt the reverse-biased diode. Melting the reverse-biased diode may induce a reduction in voltage across the current boost capacitor and result in a current surge through the programmable branch that is sufficient to program (i.e. blow) the fusable element. A corresponding method for programming a fuse is also disclosed.
    • 用于编程熔丝的装置包括可编程分支,其包括串联连接的可熔断元件和反向偏置二极管。 可编程分支与电流升压电容并联连接。 电源或输入端提供足以将电流升压电容器充电到反向偏置二极管的击穿电压并随后熔化反向偏置二极管的电流。 熔化反向偏置二极管可能导致电流升压电容器两端的电压降低,并导致通过可编程分支的电流浪涌,其足以对可熔元件进行编程(即吹)。 还公开了用于编程熔丝的相应方法。
