Abstract: Dynamic and partial sharing of the channel measurement downlink reference signal resources are provided. An apparatus performs determining information relating to an actual number of ports configured for a user equipment for channel measurements and determining a pool of channel state information reference signal resources for the user equipment. The pool of channel state information reference signal resources is provided in a radio resource control configuration and includes an excess number of ports compared to the actual number of ports. The apparatus also transmits to the user equipment via at least one of a medium access control control element or downlink control information, configured user equipment specific mapping for the pool of channel state information reference signal resources.

Abstract: A system, method, and computer-readable medium for performing a data center connectivity management operation. The connectivity management operation includes: providing a data center asset with a data center asset client module; establishing a connection between a mobile device application and a connectivity management system; submitting a request to the connectivity management system via the mobile device application to establish connectivity with the data center asset client module; establishing a connection between the data center asset client module and the connectivity management system based upon the request; and, exchanging information between the data center asset client module and the data connectivity management system via the secure communication channel between the data center asset client module and the connectivity management system.

Abstract: An electronic display assembly includes an electronic display. An upper portion is supported by a housing assembly above, and spaced apart from, the electronic display, which is also supported by the housing assembly. One or more fans associated with the upper portion move ambient air ingested through one or more intake/exhaust apertures in an upper portion housing, an upper cavity, and a transition area between the upper portion and the electronic display. Ambient air is also ingested through one or more intakes at the transition area by the one or more fans and moved towards one or more open loop airflow pathways extending behind the electronic display.

Abstract: Electroacoustic drivers that can be utilized in loudspeaker systems that utilize drivers having a magnetic negative spring (MNS) (such as reluctance assist drivers (RAD) and permanent magnet crown (PMC) drivers). The electroacoustic drivers can be used at all audio frequencies, including subwoofer frequencies. The magnetic negative springs of the electroacoustic drivers can cancel, or partially cancel, the large pressure forces on a sound panel (of an audio speaker) so that substantial subwoofer notes can be efficiently and cost effectively produced in small/portable speakers. The electroacoustic drivers can include a stabilizing/centering mechanism to overcome the destabilizing forces of a MNS that are too large for a voice coil alone to produce.

Abstract: Electronic display assemblies with forced air cooling are provided. An open loop centrifugal fan forces ambient air through an open loop pathway extending through an electronic display subassembly. A closed loop centrifugal fan forces circulating gas through a closed loop airflow pathway including a rear compartment behind the electronic display subassembly. Electronic components for operating the display assembly and changing electric vehicles may be provided with the rear compartment.

Abstract: Systems, methods, and devices enable spectrum management by identifying, classifying, and cataloging signals of interest based on radio frequency measurements. In an embodiment, signals and the parameters of the signals may be identified and indications of available frequencies may be presented to a user. In another embodiment, the protocols of signals may also be identified. In a further embodiment, the modulation of signals, data types carried by the signals, and estimated signal origins may be identified.

Abstract: A method is provided, including: defining a plurality of frequency bins; sending, during a training phase, a test signal at different amplitude levels to one or more speakers, and gathering resulting test voltage (V) and current (I) points for the different amplitude levels and for each frequency bin; for each frequency bin, applying a linear regression algorithm to the gathered test voltage and current points for the different amplitudes to obtain a reference electrical impedance of said one or more speakers; sending, during a monitoring phase subsequent to said training phase, an audio signal to said one or more speakers, and gathering resulting new voltage and current points to obtain an operating electrical impedance for said one or more speakers for each frequency bin, determining a deviation between the operating and the reference electrical impedance, and, if the deviation exceeds a defined tolerance, reporting the deviation to a user.

Abstract: An illumination system for a lighting assembly comprises a light assembly configured to selectively illuminate an operating region in a surgical suite and a plurality of light sources positioned within the light assembly and configured to emit light. The system further comprises at least one imager configured to capture image data and a controller. The controller is configured to scan the image data in at least one region of interest for a shaded region and identify a location of the shaded region within the region of interest. The controller is further configured to control the light assembly to activate at least one of the light sources to emit light impinging on the shaded region within the region of interest.

Abstract: Certain configurations of methods which can be used to produce removable oral devices are described. In some instances, the removable oral devices can be produced using molding, digital scanning, on demand printing and/or other processes. In certain examples, the produced removable oral device can be used in weight management, athletic performance or in other applications.

Abstract: Certain configurations of removable oral devices are described. In some instances, the removable oral device includes a palatal element. In certain configurations, the palatal element may comprise a variable hardness at different areas, e.g., edges can be softer than other areas of the removable oral device. In other instances, the removable oral device may comprise two or more individual palatal elements which together can form the palatal element and permit user adjustment of the oral volume. Various materials used in the palatal element are described. Sensors and other on-board devices are also described.

Abstract: A cleaning device enables cleaning of a lens of an endoscope during a surgical procedure to maintain a clear image without having to remove the endoscope from the patient's body. The cleaning device is mountable to an endoscope such that a wiper of the cleaning device is selectively displaced across the lens of the endoscope to remove debris from the lens.
