Abstract: Techniques pertaining to efficient and flexible frequency domain (FD) aggregated physical-layer protocol data unit (FD-A-PPDU) with the same and/or mixed WiFi generations transmission are described. An apparatus (e.g., a station (STA)) performs a wireless communication by: (i) transmitting a FD-A-PPDU or (ii) receiving the FD-A-PPDU. The wireless communication is performed in a 160 MHz, 240 MHz, 320 MHz, 480 MHz or 640 MHz bandwidth with 80 MHz being a minimum size of each of multiple PPDUs of the FD-A-PPDU. The FD-A-PPDU may be a 160 MHz, 240 MHz, 320 MHz, 480 MHz or 640 MHz FD-A-PPDU. The FD-A-PPDU may include PPDUs having a same PPDU format or different PPDU formats of different WiFi generations and utilizing a minimum size of 80 MHz non-overlapping frequency subblocks as a base building block.

Abstract: Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.

Abstract: Technologies for calibrating radars and tracking space objects. Some of such technologies enable a technique for calibrating a radar based on using -A- an elemental antenna (308), which can be embedded on a housing hosting a set of antenna elements, or -B- an antenna (146) mounted to a reflector. Some of such technologies enable a radar site containing a first 1D phased array (112) and a second 1D phased array (112), where the first 1D phased array sends a set of signals and receives a set of reflections based on the set of signals, and the second 1D phased array receives the set of reflections.

Abstract: There is presented a boost converter and an associated method for starting the boost converter. The boost converter includes an input terminal for receiving an input voltage, an output terminal for providing an output voltage, a low-side power switch and a high-side power switch coupled at a switching node, and a voltage regulator coupled to the high-side power switch. The boost converter is also provided with a controller for operating the boost converter in a start-up phase. In the start-up phase the controller controls the boost converter to generate an intermediate voltage and increase the intermediate voltage to a predetermined value. The intermediate voltage is then provided to the voltage regulator to obtain a drive voltage. The high side power switch is then driven to increase the output voltage linearly up to a start-up voltage.

Abstract: Refresh requests are received by a data source that each request a snapshot of current members of one of a plurality of dynamically changing groups and dynamically changing rules corresponding to such group. Thereafter, the data source queues the received plurality of refresh requests for selective execution or deletion into a new request queue. In addition, real-time execution of refresh jobs are initiated for all of queued refresh requests if a number of refresh requests in both of the new request queue and a waiting requests queue is below a pre-defined threshold. Alternatively, a job framework schedules execution of task jobs for a subset of the queued requests in the new request queue and the waiting requests queue if certain conditions are met.

Abstract: Some embodiments provide a program that receives, from an application, a role-based permission (RBP) request specifying an RBP, a first user, and a second user. The RBP specifies a set of actions, a first set of users authorized to perform the set of actions, a second set of users on which the first set of users is authorized to perform the set of actions, and a relationship condition. When the relationship condition specifies a hierarchy-based relationship, the program determines valid users in the second set of users according to a hierarchy of users. When the relationship condition specifies a non-hierarchy-based relationship, the program determines valid users in the second set of users according to a relationship not based on the hierarchy of users. The program determines whether the first user is authorized to perform the set of actions on the second user based on the determined valid users.

Abstract: Described herein is a framework for providing and securing data access by external users. In accordance with one aspect of the framework, an external schema is generated to pair with an existing company schema in a database. The company schema may own data stored in the database. One or more access-control views that expose one or more subsets of the data may further be generated. The external schema may be granted access to the one or more access-control views. Synonyms may be created to rename access-control views, so that the synonyms share common names with corresponding database objects accessible via the company schema. External users may then access the data visible to them via the synonyms that are used to alias the access-control views.

Abstract: Various embodiments of the present disclosure provide improved systems and techniques for intelligently allocating cache requests to caches based upon the nature of the cache objects associated with the cache requests, and/or the condition of the caches in the distributed cache system, to facilitate cache system utilization and performance. In some embodiments, an allocation of cache requests may be performed in response to detection of a problem at one of a group of cache servers. For example, in some embodiments, a particular cache server may be entered into a safe mode of operations when the cache's ability to service cache requests is impaired. In other embodiments, an allocation of cache requests may be performed based on an cache object data type associated with the cache requests.
