Abstract: Disclosed herein is a memory cell including a memory element and a selector device. Data may be stored in both the memory element and selector device. The memory cell may be programmed by applying write pulses having different polarities and magnitudes. Different polarities of the write pulses may program different logic states into the selector device. Different magnitudes of the write pulses may program different logic states into the memory element. The memory cell may be read by read pulses all having the same polarity. The logic state of the memory cell may be detected by observing different threshold voltages when the read pulses are applied. The different threshold voltages may be responsive to the different polarities and magnitudes of the write pulses.

Abstract: A method of treating a heart of a patient is provided, including implanting a first tissue anchor in cardiac tissue of the patient, the first tissue anchor attached to one or more tethers that are fixed to a coupling element. A second tissue anchor is implanted in the patient. The coupling element is coupled to a first coupling site of the second tissue anchor, thereby coupling the first tissue anchor to the second tissue anchor via the one or more tethers. Thereafter, after allowing at least 24 hours for tissue growth on the first tissue anchor to strengthen anchoring of the first tissue anchor in the cardiac tissue, tension is increased between the first and the second tissue anchors by decoupling the coupling element from the first coupling site and coupling the coupling element to a second coupling site of the second tissue anchor. Other embodiments are also described.

Abstract: Techniques of tracking a hand controller in a VR system involves detecting, by photodiodes in the hand controller, patterns of diffuse radiation generated by diffuse LEDs in the HMD. Such techniques can also include comparing the detected patterns to those simulated offline previously and represented in a lookup table (LUT). By looking up the detected patterns in the LUT, the VR system may determine the position and/or orientation of the hand controller with sub-millimeter accuracy. Some advantages of the improved techniques can be in the simplicity and/or low cost of the components without sacrificing accuracy in deriving the position and orientation of the hand controller.
