A radio frequency receiver subject to a large in-band interferor employs active cancellation with coarse and at least one cancellation signals, each with a respective radio frequency combiner, in order to increase the effective dynamic range of the receiver for weak signals of interest. One or both can be digitally synthesized. This is particularly applicable for co-site interference, whereby the interfering transmit signal is directly accessible. A similar system and method may also be applied to external interferors such as those produced by deliberate or unintentional jamming signals, or by strong multipath signals. An adaptive algorithm may be used for dynamic delay and gain matching. In a preferred embodiment, a hybrid technology hybrid temperature system incorporates both superconducting and semiconducting components to achieve enhanced broadband performance.

A first elastic body actuator and a second elastic body actuator are used for driving a first configuration member and a second configuration member to swing them with respect to each other. One end portion of the first elastic body actuator is secured to the first configuration member and the other end portion of the first elastic body actuator is secured to the second configuration member, and one end portion of the second elastic body actuator is secured to the first configuration member and the other end portion of the second elastic body actuator is secured to the second configuration member, such that the position at which the other end portion of the second elastic body actuator is secured to the second configuration member and the position at which the one end portion of the first elastic body actuator is secured to the second configuration member are substantially symmetric about a rotational joint. The interval between the portion of the first elastic body actuator, which is secured to the second configuration member, and the portion of the second elastic body actuator, which is secured to the second configuration member, is moved by a securing-position variable mechanism.

The invention relates to a ladder type working platform which comprises a folding ladder and a working table arranged at the upper part of the folding ladder, wherein the working table consists of a bearing bottom surface and a guardrail arranged around the bearing bottom surface in a surrounding way; the guardrail comprises a left side frame and a right side frame; main body structures of the left side frame and the right side frame respectively comprise a first connecting rod, a second connecting rod and a third connecting rod which are arranged on the same plane; the first connecting rod is connected with the third connecting rod in a pivoting way; the first connecting rod is connected with the bearing bottom surface in a pivoting way; the second connecting rod is connected with the third connecting rod in a pivoting way; the second connecting rod is connected with the bearing bottom surface in a pivoting way; the folding ladder comprises a front ladder and a rear ladder; the front ladder comprises a left support pillar and a right support pillar; the left support pillar is fixedly connected with the first connecting rod of the left side frame, and the right support pillar is fixedly connected with the first connecting rod of the right side frame; and the rear ladder is provided with a stop support piece corresponding to the bearing bottom surface. The ladder type working platform solves the problems that in the prior art, the folding ladder is small in trample area and can not be rotated, and the direction of the folding ladder can not be changed.
