    • The sleeper storage apparatus is partially made of a pliable rectangular panel substantially sized to match a length and width dimension of a bunk in a sleeper cab. The first round rigid spine is removably affixed within the panel top, with a plurality of spaced apart upper straps removably affixed to the first rigid spine. The second rigid spine is removably affixed within the panel bottom with a plurality of spaced apart lower straps removably affixed to the second spine. Each of the upper straps is selectively hooked to one of each of the lower straps, each attached upper and lower strap forming a strap pair. Each strap pair is removably wrapped around the bunk. A plurality of pliable pockets is affixed to the panel, including a hamper pocket with lower opening and trap door to ease in emptying.

    • A method of performing a frequency correction of a radio module. Multiple samples of frequency data during a quiescent portion of the base station transmission is taken to estimate the amount of frequency correction needed. An embodiment applies the frequency data to a median filter to eliminate invalid data. Next, a new reference frequency is applied to a radio transceiver in the radio module to provide the frequency correction. If the frequency was corrected by greater than a pre-determined amount, the process performs a large shift frequency correction, including verifying that the first frequency correction was satisfactory and verifying that the radio transceiver is able to receive data after the frequency correction has been performed. If the frequency was corrected by smaller than a pre-determined amount, the process performs a small shift frequency correction, including updating a total of all frequency corrections made since a stored reference frequency was updated.
    • 执行无线电模块的频率校正的方法。 采用在基站传输的静止部分期间的频率数据的多个样本来估计所需的频率校正量。 一个实施例将频率数据应用于中值滤波器以消除无效数据。 接下来,将新的参考频率应用于无线电模块中的无线电收发器以提供频率校正。 如果频率被校正大于预定量,则该处理执行大的移位频率校正,包括验证第一频率校正是令人满意的并且验证无线电收发机能够在执行频率校正之后接收数据 。 如果频率被校正小于预定量,则该处理执行小的移位频率校正,包括更新从存储的参考频率更新以来所做的所有频率校正的总和。

    • Probe accessories, and methods for routing signals between a target and a test instrument using the probe accessories, are disclosed. Some of the probe accessories include a flexible circuit and first and second pairs of contacts. Flexible circuit design varies, but one embodiment has first and second regions, a first conductor and a second conductor, and a separation feature. The first conductor extends into the first region while the second conductor extends into both the first and second regions and has a fixed spacing with respect to the first conductor. A separation feature extends between first and second regions and is operable to create two independently maneuverable legs, each leg comprising an end portion of the first and second regions, while maintaining a fixed spacing between the first and second conductors. The first and second pairs of contacts electrically couple the probe accessories between test points and test instruments.

    • A probe for an array of interconnecting leads between a PCA and an IC has one or more contacts extending laterally from or plated upon one or more arms formed of a flexible printed circuit, and connected by traces along the arm(s) to a header that itself affords connection to measurement equipment. The flexible printed circuit is thin enough to loosely slide between the top of the PCA or PCB and the bottom of the IC. The arm or arms is/are narrow enough to slide between the adjacent leads forming the array, while the normally flat contacts will successively interfere with, to engage and electrically contact, consecutive layers of leads as the probe is progressively inserted. An arm is not so stiff that it cannot yield by a slight compressive warping as the contacts encounter leads. Indexing may be ‘by feel’ or by visible indicia along a top surface of the probe or by a reticle device that moves over the top of the IC, which then has a pattern of indicia corresponding to lead location. Forming the shape of a Kapton substrate may also include use of a CVL operating in the range of 250 nm to 290 nm for the creation of extended copper contacts by the removal of underlying Kapton. Plating processes may also be used in the fabrication of (non-extended) wrap-around contacts at the edges of the Kapton.
    • 用于PCA和IC之间的互连引线阵列的探针具有从柔性印刷电路形成的一个或多个臂横向延伸或镀覆在一起的一个或多个触点,并且通过沿着臂的迹线连接到头部, 本身提供与测量设备的连接。 柔性印刷电路足够薄,以便在PCA或PCB的顶部和IC的底部之间松动地滑动。 臂或臂足够窄以在形成阵列的相邻引线之间滑动,而当探针逐渐插入时,通常平坦的触点将连续地干扰,接合和电接触连续的引线层。 手臂不那么僵硬,以至于由于接触碰撞而导致轻微的压缩翘曲不能屈服。 索引可以是“通过感觉”或通过沿着探针的顶表面的可见标记或通过在IC的顶部上移动的掩模版设备,其然后具有对应于引线位置的标记图案。 形成Kapton衬底的形状还可以包括使用在250nm至290nm范围内工作的CVL,以通过去除下面的Kapton来产生扩展的铜触点。 电镀工艺也可用于制造Kapton边缘的(非延伸)环绕触点。
