Abstract: Various arrangements for cellular networks are presented herein. The cellular network can include a first radio unit, wherein first communications for the first radio unit on a cellular network are performed as part of a first cellular network slice. The cellular network can include a second radio unit, wherein second communications for the second radio unit on the cellular network are performed as part of a second cellular network slice. A distributed unit of the cellular network is in communication with the first radio unit and the second radio unit. The second communications can be routed in encrypted form to a data center that is separate and distinct from the cellular network.

Abstract: An embedded sensor can include an audio detector, a digital signal processor, a library, and a rules engine. The digital signal processor can be configured to receive signals from the audio detector and to identify the environment in which the embedded sensor is located. The library can store statistical models associated with specific environments, and the digital signal processor can be configured identify specific events based on detected sounds within the particular environment by utilizing the statistical model associated with the particular environment. The DSP can associate a probability of accuracy for the identified audible event. A rules engine can be configured to receive the probability and transmit a report of the detected audible event.

Abstract: Various arrangements for allocating spectrum between a cellular network provider and a secondary operator are presented. A cellular network component of the secondary operator may determine that spectrum at a secondary operator radio unit (RU) is not currently needed. The cellular network component of the secondary operator may cause the spectrum to be released for use by a cellular network operator such that the secondary operator RU is not permitted to use the released spectrum. A cellular network operator RU may then communicate with a first set of user equipment (UE) using the released spectrum. The secondary operator RU and cellular network operator RU may be located at a same location.

Abstract: A gimbal apparatus is disclosed, including a tubular envelope with a variable length between first and second rim structures. A rigid ring structure inside the tubular envelope is connected to diametrically opposite first and second portions of the first rim structure, and is connected to diametrically opposite first and second portions of the second rim structure. A spoke bisects the ring structure.

Abstract: A heterodyne system provides a first signal and a second signal in response to a received drive signal, wherein the frequency of the first signal divided by the frequency of the second signal is an integer ratio. A mixer receives the first signal and the second signal and provides a series of mixing products. Spurious signals generated by the mixer are offset from a designated one of the mixing products by integer multiples of the frequency of the second signal divided by the denominator of the integer ratio when the integer ratio is reduced to its lowest terms.
