Abstract:

The technologies described herein are generally directed to facilitating operation of a system for implementing fifth generation (5G) or other next generation networks. In accordance with one or more embodiments, a method described herein can include identifying, by a device comprising a processor, predicted resource usage of a first antenna covering a geographic zone. Further, the method can include selecting, by the device, a group of geographic siting locations within the geographic zone for potentially siting ones of a group of second antennas. In addition, selecting, by the device, a spatial arrangement in relation to the first antenna, of a subset of the group of geographic siting locations can occur, with a selected spatial arrangement including an arrangement to maintain the predicted resource usage in the condition.

International Classification:

G06K 9/00

Abstract:

Aspects of the present disclosure describe systems, methods, and structures that provide action recognition with high-order interaction with spatio-temporal object tracking. Image and object features are organized into into tracks, which advantageously facilitates many possible learnable embeddings and intra/inter-track interaction(s). Operationally, our systems, method, and structures according to the present disclosure employ an efficient high-order interaction model to learn embeddings and intra/inter object track interaction across the space and time for AR. Each frame is detected by an object detector to locate visual objects. Those objects are linked through time to form object tracks. The object tracks are then organized and combined with the embeddings as the input to our model. The model is trained to generate representative embeddings and discriminative video features through high-order interaction which is formulated as an efficient matrix operation without iterative processing delay.

International Classification:

H04W 64/00
G01S 5/10

Abstract:

Techniques for locating a mobile device using a time distance of arrival (TDOA) method with disturbance scrutiny are provided. In an aspect, for respective combinations of three base station devices of a number of base station devices greater than or equal to three, intersections in hyperbolic curves, generated using a closed form function with input values based on differences of distances from the device to pairs of base station devices of the respective combinations of three base station devices, are determined. The intersection points are then tested for robustness against measurement errors associated with the input values and a subset of the intersection points that are associated with a degree of resistance to the measurement errors are selected to estimate a location of the device.

Appl. No.:

15/348571

Inventors:

Jie Chen - Saint Charles MO, US
Jan Pottinger - O'Fallon MO, US

International Classification:

F25B 45/00

Abstract:

A method for charging a field refrigeration system including an evaporator, a condenser, a compressor, and an expansion device includes calculating a target superheat as a function of one or more of a measured field outdoor dry bulb temperature, and a measured field indoor wet bulb temperature. A charge adjustment percentage can be calculated as a function of the target superheat. A refrigerant adjustment weight can be determined based on the charge adjustment percentage. A field refrigeration system charge can be adjusted by the refrigerant adjustment weight.

International Classification:

F25B 45/00

Abstract:

A method for charging a field refrigeration system including an evaporator, a condenser, a compressor, and an expansion device includes calculating a field subcooling of the field refrigeration system as a function of a measured field liquid line pressure and a measured field liquid line temperature. A charge adjustment percentage can be calculated as a function of the field subcooling, a measured field indoor wet bulb temperature, and a measured field outdoor dry bulb temperature. A refrigerant adjustment weight can be determined based on the charge adjustment percentage. A field refrigeration system charge can be adjusted by the refrigerant adjustment weight.
