Abstract:

Methods, systems, and computer programs are presented for reducing latency for providing a user feed containing one or more posts. One method includes operations for receiving a request to access the user feed and for performing a first query to search posts. The first query uses a first time horizon delimiting a creation time of posts and a first maximum number of posts selected for ranking. The posts from the first query are sent to the client device for presentation on a user interface. Further, a second query is performed to search posts, where the second query uses a second time horizon that is greater than the first time horizon and a second maximum number of posts for ranking that is greater than the first maximum number of posts. The posts from the first query and the second query are merged and sent to the client device for presentation.

Assignee:

Archimedes Controls Corp. - Pleasanton CA

International Classification:

H04Q 9/00

Abstract:

An adaptive algorithm based battery-powered long distance wireless temperature and humidity sensor module. The sensor module uses an adaptive algorithm to transmit data on an event basis and/or a reduced basis to extend battery life to more than 10 years. It also uses a low power wireless transmitter which has frequency of sub-1 GHz and an effective transfer distance of up to 250 meters, a low power temperature and humidity sensor, and a long lasting lithium battery which has shelf life of 20 years.

International Classification:

G06N 3/08

Abstract:

Described are methods and systems for identifying an electrical load device electrically coupled to a smart plug device. In some embodiments, a server receives, from the smart plug device, a plurality of power properties associated with the electrical load device. The server inputs the plurality of power properties into a plurality of nodes of an artificial neural network (ANN) graph to generate a predicted device ID. The server queries a database for a device ID that is within a threshold of the predicted device ID. Based on querying the database to determine that the device ID exists, the server identifies the electrical load device as a device associated with the device ID.

International Classification:

F24F 11/00
G05B 19/048

Abstract:

The present invention is a complete solution for mission critical facilities to create a safe environment and energy efficient CRAC system. The invented system collects mission critical facility volume environmental and energy data in real time, and uses big data analytics to provide adaptive group control to CRACs. The data is visualized in 2D and 3D graphs, dashboard, history curves and reports locally and through the cloud. The present invention also provides user management to allow authorized users to view and control the racks/servers owned or rented by these users. The present invention is comprised of four companion patents: 1) A Battery-powered Wireless Long Life Temperature and Humidity Sensor Module, 2) An Intelligent Multi-channel Wireless Data Acquisition Gateway, 3) Mission critical facility Three Dimension Temperature Contour Generator, and 4) An Adaptive Automatic CRAC Master Control Method.

International Classification:

F24F 11/00
H05K 7/20
G05B 15/02

Abstract:

Described is an adaptive automatic computer room air conditioner (CRAC) or computer room air handler (CRAH, CRAC and CRAH is referred interchangeably in this article) group control method. This method automatically controls each HVAC unit's on/off status, return temperature set point, fan speed or cooling valve position to secure the data center thermal environment for server's secure running and minimize the cooling energy use. The method creates a comprehensive feedback control loop between temperature sensor network, data center environment and CRACs.

Abstract:

The present invention is an intelligent gateway which can receive multiple sensor data using sub-1G Hz frequency, analyze data, and transmit processed data to a database server. The intelligent gateway can receive data from up to 100 sensors using sub-1G Hz (433, 868 or 915 MHz) wireless frequency. The received data can be analyzed and the gateway can determine when to transmit data, and which packaged data to transmit to the database server. The intelligent gateway can also receive feedback and instructions from the database server. The process data can be transmitted to the database server with different protocols like WIFI, Ethernet and RS485. The intelligent gateway can also include multiple sensors including temperature and humidity sensors, pressure sensors, air speed sensors and a particulate matter sensor for detecting particulates of less than 2.5 micro meters (PM2.5). These sensors are collect additional indoor environmental quality parameters.
