Title: Trigger-based random access in a multiple bssid network
Inventor: PATIL ABHISHEK PRAMOD
IPC: H04W76/11
Filed: 2018-04-11
Abstract: This disclosure provides systems, methods, and apparatuses for allocating wireless resources to a multiple basic service set identifier (BSSID) set including a number of BSSIDs each associated with a corresponding one of a number of access points (APs). An AP may allocate random access resources for use by stations belonging to the multiple BSSID set using a number of association identifier (AID) values based on a group AID mapping contained in a partial virtual bitmap of a traffic indication map (TIM) element. The AP may transmit a trigger frame containing the number of AID values to the stations belonging to the multiple BSSID set.

Abstract: Provided herein are separation processes for metal ions present in aqueous solutions based on methods involving liquid-liquid extraction. The separation process involves a chelator that can selectively bind to at least one of the metals at a relatively low pH. This can be used, for example, for recovery and purification of actinides from lanthanides, separation of metal ions based on their valence, and separation of metal ions based on the pH of the extraction conditions.

Abstract: A method of making a semi-conductor heat sink mount- ng includes two extrusion steps. Initially, a substantially :ylindrical copper billet having an upper cylindrical locating portion of reduced diameter is formed. A steel ring is then brazed to the copper billet about the locating portion. The billet and the steel ring are then extruded to form a sink body portion (22), a pedestal portion (24) extending upwardly from the body portion and defining a disc receiving recess, and a resistance welding ridge (27) surrounding the pedestal portion. A molybdenum discs (28) is brazed into the recess in the pedestal portion. A stem (38) is then extruded downwardly from the body portion (22) as a substantially evenly distributed downward force is applied to the body portion, the pedestal portion and the molybdenum disc. This force prevents structural failure of the molybdenum disc by maintaining the disc in compression while the stem portion and the body portion of the heat sink mounting are worked to a full hard state.

Abstract: An improved fuel-air admission assembly incorporating a split coal bucket which permits a pulverized coal-fired furnace to be operated at low loads without the use of auxiliary fuel to provide stabilization. The split coal bucket comprises an upper and a lower coal nozzle pivotally mounted to the coal delivery pipe, the upper and lower coal nozzles being independently tiltable. When the furnace is operating at low loads, the primary air and pulverized coal stream discharging from the coal delivery pipe is split into a first and a second-air stream and independently directed into the furnace by tilting at least one of the nozzles away from the longitudinal axis of the coal delivery pipe, thereby establishing an ignition stabilizing pocket in the locally low pressure zone created between the spread apart coal-air streams.

Abstract: La détermination du pH, de la pression partielle de gaz carbonique (pCO 2 ) et de la pression partielle d'oxygène (pO 2 ) dans le sang est une procédure de diognos- tic bien établie, utilisée avec certains traitements médicaux et chirurgicaux. 
     Différents instruments ont été étudiés et mis au point pour déterminer le pH, le pC0 2  et le pO 2  du sang. Il est de pratique courante d'employer des solutions contrôles pour vérifier la précision et la fiabilité de ces appareils. On a constaté cependant, qu'après un certain laps de temps, la matière protéine des échantillons de sang appliqués sur l'instrument avait tendance à s'accumuler sur la mebrane de l'électrode et à engorger ainsi les pores de la matière constituant la membrane semi-perméable ou à contaminer d'une autre façon les tubes des instruments. 
     Ces inconvénients ont été supprimés par la mise au point d'un étalon de contrôle de liquide synthétique comprenant une solution aqeuse de teinture tamponnée à un pH de 7.1 à 7.7 environ et contenant suffisamment de ions bicarbonate pour assurer un pC0 2  de 20 à 80 environ, de glycol éthylénique pour assurer une viscosité de 3 à 9 centipoises environ, et d'oxygène gazeux pour assurer un pO 2  de 50 à 400 environ, contenue dans un réceptacle hermétique.

Abstract: A glass layer (2); is formed inside a silica glass tube (3) and another glass layer (1) having a refractive index higher than that of the abovementioned glass layer (2) is formed on said glass layer (2). After these glass layers (1,2) are formed, one end of the glass tube (3) is collapsed. While the internal pressure of the glass tube is being reduced below the atmospheric pressure, the glass tube is caused to collapse by heating, thereby yielding a preform for an optical fiber. The optical fiber produced from this preform has the difference in the refractive indices of the two orthogonal major axes (x, y) of at least 1.6 x 10 -4  and maintains the linear polarization plane.

Abstract: The present invention provides RAM locations in a main processor to store the inputs from other input/output processors. Thus, inputs to an input/output processor are also conveyed over a communication channel to the main processor and stored in the main processor's RAM. All control functions or processors needing a particular input value or responding to certain input values, would look to the input values stored in the master processor memory rather than in the local input/output processor. Inputs to any particular input/output processor or control code relying on the inputs can then be shifted to other processors. This would not effect the control since the control responds to the inputs centrally located in the master processor RAM.

Abstract: A reciprocating labelling device is known but it is slow and expensive. High speed labelling devices can only handle paper labels and cannot be used with plastic labels. The invention provides a high speed compact labelling device particularly adapted for use with plastic labels comprising a rotary label applying means (120) having a plurality of bellows (124) arranged at intervals therearound. The label applying means is adapted to rotate between a label receiving position and a label applying position. A vacuum is applied to the bellows to retract them except at the label applying position and labels are held on the retracted bellows by suction. At the label applying position an overpressure is applied to the bellows causing the bellows to expand into contact with an object to be labelled. Objects of irregular size can thus be labelled. 
     The apparatus also includes a detachable cassette (12) for a supply (16) of labels (22), the cassette including means for transporting labels (30) to the label applying means and for separating labels (32) from the label carrier (20). The cassette can be loaded and threaded up when detached from the rest of the apparatus and when loaded can replace an exhausted cassette on the apparatus without stopping the apparatus.
