Abstract: Techniques for determining calibration data associated with a radio frequency (RF) testing environment are discussed herein. For example, an RF signal can be input to the RF enclosure and selectively applied to discrete attenuators. The attenuators can attenuate a strength of the signal and a signal strength can be measured by various user equipment (UEs) that are located within an RF enclosure. In some examples, a plurality of measured reference signal received power (RSRP) values can be determined by a plurality of UEs associated with a particular attenuation level. Different attenuation levels can be measured, and an average attenuation can be determined for attenuation steps. Measured attenuation steps can be extrapolated to other attenuation levels to expedite the calibration process. Then, a testing plan can be applied to the RF enclosure and the calibration data can be used to ensure accurate signals for testing UEs.

Abstract: The disclosed principles provide for single use caps that may be applied to any of a number of receptacles, containers, vessels, needless connectors, or other device. A single use cap as disclosed herein includes a component that, when the cap is threaded onto a receptacle or device, is moved from an “unused” to a “used” position by the twisting force applied to the cap when secured onto the receptacle or device. Specifically, once the threads of the receptacle or device are received into the cap and a twisting or tightening force is continued to be applied to the cap, the continued twisting force causes this component to rotate laterally so that once the cap is removed from the receptacle or device, the threads of the cap are no longer reachable by the threads on the receptacle or device.

The first and second vacuum orifices are on opposing sides of the blade.
