Abstract: A medical device position guidance system includes at least one reference transmitter, a receiver system comprising at least two sensors configured to receive signals from the at least one reference transmitter and move relative to the at least one reference transmitter, and a processor. The at least one reference transmitter is configured to maintain a fixed position relative to a subject. The at least two sensors are enclosed in a unitary receiver housing. The at least one reference transmitter and the receiver system are operatively coupled to the processor. The system also includes a memory device storing instructions which when executed by the processor, cause the processor to receive signals relating to a location and orientation of the receiver system relative to the at least one reference transmitter and using the received signals, create an anatomical coordinate system.

Abstract: Improved telescoping railcar uncoupling levers have improved bearings that resist damage. Moreover, the uncoupling levers include removable lock lifter linkage hooks. In addition, the uncoupling levers comprise an improved handle loop shape allowing the levers to be more easily installed and/or removed when damaged. Methods of using the same are further provided.

Abstract: A traffic-and-billing system imports a chronological schedule from a media automation system. The schedule includes media and advertisement spots allocated in accordance with a content allocation prediction, which allocates a portion of the advertisement spots to general content and a portion to local content. The traffic-and-billing system stores information associated with general advertisement content and generates a content listing based on the content allocation prediction. A general advertisement system receives, an update request that indicates at least one item of the general advertisement content is to be removed from the content listing. The general advertisement system plays out general advertisement content items included in the general advertisement content listing in response to receiving a playout request from the media automation system.

Abstract: A medical device position guidance system is provided. The system includes at least one reference transmitter and a receiver system configured to receive signals from the at least one reference transmitter. The reference transmitter is configured to maintain a static position on a subject. The system further includes a processor configured to (i) receive signals relating to the location and orientation of each sensor of the receiver system relative to the at least one reference transmitter; and (ii) using the received signals, create an anatomical coordinate system. The system may further include an inserted transmitter configured to be attached to a medical device. The inserted transmitter is adapted to establish the location and orientation of the medical device within the anatomical coordinate system. A method for medical device position guidance is also provided.

Abstract: The subject matter described herein presents various technical solutions for the technical problems facing autonomous vehicles (e.g., fully autonomous and semi-autonomous vehicles). To address technical problems facing wireless communication cost and latency, a heterogeneous roadside infrastructure can be used to improve the ability for a vehicle to communicate with a data source. To address technical problems facing interruption of vehicle services due to an abrupt loss of connection, a quality of service system provides the ability to determine and share quality of service information, such as location-based information, maps, interference data, and other quality of service information. To address technical problems facing high volume data upload and download between autonomous vehicles and cloud-based data services, optical wireless communication (OWC) provides increased data throughput and reduced complexity and may be beneficial for short-range high-mobility wireless communications.

Abstract: Embodiments of the present disclosure are directed to techniques for transitioning a spacecraft from a power-saving state to a power-consuming state at a time after launch of the spacecraft on a launch vehicle. Because the spacecraft can detect conditions for transitioning to the power-consuming state, commands received via an umbilical connection to the launch vehicle, or detecting the presence or absence of such a connection, is unnecessary, thereby removing several technical barriers to eliminating such umbilical connections altogether.

Abstract: A ball including a microprocessor operable to execute a processor readable code to convert sensor data generated by at least one sensor to ball movement values, compare the ball movement values to ball movement threshold values, and actuate one or more light emitters or sound generators upon ball movement values satisfying the ball movement threshold values.

Abstract: An electric tricycle including a frame having a front end coupled to a steering assembly, the steering assembly having a front wheel, and a rear end coupled to a rear wheel assembly, the rear wheel assembly having two rear wheels. At least two pedals rotatably coupled to the rear wheel assembly and configured to move in a reciprocating motion, the at least two pedals having an engaged configuration wherein the at least two pedals are engaged with the two rear wheels and configured to rotate the two rear wheels in a first direction, and a disengaged configuration wherein each of the at least two pedals is disengaged from the two rear wheels and aligned with another of the at least two pedals. An electric motor electrically coupled to a battery and configured to engage with the two rear wheels and to rotate the two rear wheels in the first direction.

Abstract: The present disclosure provides a device for measuring the jugular venous pressure of a patient. The device comprises a body defining a longitudinal enclosure and having a window along a length of the longitudinal enclosure to allow light to exit the longitudinal enclosure, a beam generator comprising a moveable portion mounted within the longitudinal enclosure, the beam generator configured to generate a sheet of light along a plane perpendicular to a longitudinal direction and at an adjustable position along the longitudinal direction, and direct the sheet of light out the window, an adjustment mechanism for adjusting the position of the moveable portion of the beam generator relative to the body along the longitudinal direction, and, a readout indicating the position of the sheet of light along the longitudinal direction.

Abstract: A steering rack support assembly with a support shaft and a sleeve. The support shaft has a first end, a second end, and at least two mounting members. The cross section of the support shaft may be substantially the same along the length of the support shaft. A first of the at least two mounting members may be affixed to the first end of the support shaft, while a second of the at least two mounting members may be affixed to the second end. Each of the at least two mounting members may be configured to couple to the frame of the vehicle. The sleeve is disposed around an outer surface of the support shaft and is slidably coupled to the support shaft. A bracket affixed to the sleeve may be configured to couple to a rack and pinion assembly, a first tie rod, and a second tie rod.

Abstract: Methods and devices to split electromagnetic waves across broad bandwidths in correspondence with orbital angular momentum states combined with orthogonal polarization states are disclosed. The described methods can be used in fiber communication and imaging systems. The devices include three-dimensional (3D) scattering structures that can be using existing CMOS processes and direct write lithography techniques. Performance metrics based on the intensity and contrast of the split electromagnetic waves are also disclosed.

Abstract: This disclosure relates to methods of producing induced pluripotent (iPS), multipotent, and/or lineage-committed stem cells from differentiated cells, maintaining iPS, multipotent, and/or lineage-committed cells in culture, and re-differentiating the iPS and multipotent stem cells into any desired lineage-committed cell type.
