Abstract: The technical description relates to an expandable intervertebral spacer configured to engage an intervertebral disk. An example expandable intervertebral spacer includes a main body, a first endplate, a second endplate, a driving member, and an actuation member. The expandable intervertebral spacer is transitions from a first configuration to a second configuration by structural interfacing between steps defined on the first endplate, the second endplate, and the driving member. Steps include a surface that lies on a plane disposed at a non-parallel angle to the longitudinal axis of the intervertebral spacer.

Abstract: The described systems and related test methods provide significant improvement in test accuracy, as well as reduction of test time for Electromagnetic Environmental Effects (E3) system level testing. Systems may include a real time spectrum analyzer, a network analyzer, and a switching/filtering/coupling network controlled by an information processing device, such as a general purpose computer. These systems can scan all frequencies at each receiver.

Abstract: A multi-sensor input device includes multi-color lights to illuminate a user's hand with various colors of light including visible and infrared, as well as sensors including a photodetector, a red-green-blue (RGB) camera, and an infrared camera. During operation, sensor data generated by the sensors may represent non-biometric input such as a barcode that is printed or shown on another device's display, biometric input such as images of surface and subcutaneous features of the user's hand, and so forth. The biometric input may then be processed to identify the user. The input device also includes antitamper features to improve security. The input device may be used at various locations, such as at an entry portal, point of sale, and so forth.

Abstract: The technical description relates to mixed reality, augmented reality, and their use in the sharing of information about a procedure and in the performing of a procedure. A method for sharing information about a procedure and performing the procedure includes using a mixed reality system in a first location to display a mixed reality image having a virtual element representing information related to the procedure, instructing an information recipient to use an augmented reality system to view the virtual element, interacting with the virtual element to create a transformed virtual element, and manipulating a physical element in a second location while performing the procedure. Specific examples described herein relate to the field of medicine, and to orthopedics in particular.
