Title: Sliding sleeve having indexing mechanism and expandable sleeve
Inventor: Dick S Gonzalez
IPC: E21B43/26
Filed: 2016-06-07
Abstract: A downhole tool (100), such as a sliding sleeve, is operable with pressure applied against one of a plurality of plugs deployed in the tool. A sleeve (160) can engage the deployed plugs and can move with the engagement. The sleeve extends in an absence of external support and releases the engaged plug. However, an indexing mechanism (130) is operable between the sleeve and an insert (120) in the tool. The indexing mechanism moves with the sleeve in response to the engagement with the deployed plugs and counts those engagements. In response to a predetermined count, the indexing mechanism forms the external support of the one deployed plug engaged in the sleeve and moves the insert with the pressure applied against the one deployed plug, which is engaged in the sleeve and supported by the indexing mechanism. For example, the insert can move open in the tool relative to a flow port communicating outside the tool.

Title: Quantization of spatial audio direction parameters
Inventor: ADRIANA VASILACHE
IPC: G10L19/035
Filed: 2019-08-16
Abstract: Several spatial audio direction parameters 601 each have elevation and azimuth values and an ordered position. For any parameter whose elevation and azimuth values were not differentially encoded with respect to a preceding frame 602, differential parameters are obtained 604. Each parameter also has a quantised difference parameter generated 603 based on its difference from a rotated derived audio direction parameter (RDAP). For each parameter, either the differential parameter or the quantized difference is selected 610. The RDAP may be obtained by assuming a spatial distribution of parameters such as even spacing around a circle or 180 degrees, and rotating that distribution by the azimuth of the first parameter. The parameters may then be reordered according to which is closest to each RDAP. Differential parameters may be obtained depending on whether either the elevation or azimuth change by less than a threshold value relative to a preceding frame.
