    Abstract: A testing apparatus for testing a battery's responses to charge and discharge cycles includes components that enable greater control over the compressive force applied to the battery being tested than typical testing apparatuses. A force applicator of the testing apparatus is able to effect an adjustable, non-linear force (e.g., according to a parabolic curve) on a battery undergoing testing, which typical techniques using mechanical springs are unable to do. A controller may adjust a force that the force applicator applies, according to a test procedure, based on information captured by at least one sensor. The testing apparatus may include sensors for measuring a thickness of the battery, and thereby an amplitude of battery swelling, over time.

    Abstract: To provide a jig and a test piece capable of assessing a delayed fracture in a sheared end surface more accurately and easily, and a method for assessing a delayed fracture using the same. A jig (1) for assessing a delayed fracture applies a tensile load to a test piece (10) having pin holes (10A, 10B) opened on both sides in a longitudinal direction, and is installed in a hydrogen intrusion environment together with a test piece (10) restrained in a load state. A first pin (2) that penetrates one pin hole (10A) and a second pin (3) that penetrates the other pin hole (10B), a frame component (5) provided with first insertion holes (5Aa, 5Ba) into which each of both end portions of the first pin (2) is inserted; a slide component (6) provided with second insertion holes (6Aa, 6Ba) into which both end portions of the second pin (3) are inserted, and a tensile force adjustment mechanism configured to connect the slide component (6) to the frame component (5) to be able to advance and retreat along the longitudinal direction of the test piece (10), in which the tensile force adjustment mechanism is a feeding screw mechanism that moves linearly with rotation of a screw (7).

    Abstract: In an environment of a medical imaging or therapy system (1) radio frequency (RF) noise should be suppressed and/or avoided. This is achieved by a system for monitoring radio frequency (RF) noise and a computer-implemented method for suppressing and/or avoiding radio frequency (RF) noise. Whereby the medical imaging or therapy system (1) is located inside an operation room (2), the system comprising: a plurality of sensors (4, 5, 7), wherein the sensors (4, 5, 7) are configured for continuous broadband detection of radio frequency (RF) signals, wherein a first sensor (4) is located inside the operation room (2) and a second sensor (5) is located outside the operation room (2), wherein the sensors (4, 5, 7) are configured to provide sensor data, the system further comprising: a processor unit (8), wherein the sensors (4, 5, 7) are connected to the processor unit (8), the processor unit comprising: at least one memory (9) for storing instructions; at least one processor (10) that executes the instructions to cause the following to be performed: calculating a noise level and spectrum based on the sensor data in the processor unit (8); carrying out a procedure for suppressing and/or avoiding RF noise and spurious signals based on the noise level.
