A directional coupler includes a primary transmission line electrically coupled in series between an input port and an output port of the coupler, and an asymmetric, meander-shaped, secondary transmission line, which is electrically coupled in series between a coupling port and an isolation port of the coupler. The secondary transmission line includes a first coupling segment, which is reactively coupled to a first portion of the primary transmission line, and a second coupling segment, which is reactively coupled to a second portion of the primary transmission line, and is spaced closer to, or farther from, the primary transmission line relative to the first coupling segment, such that an asymmetry in reactive coupling is present between the first and second portions of the primary transmission line and the secondary transmission line. An intermediate segment is provided, which is electrically coupled in series between the first and second coupling segments. A coupling port segment is provided, which is electrically connected in series between the first coupling segment and the coupling port. And, an isolation port segment is provided, which is electrically connected in series between the second coupling segment and the isolation port.

This disclosure relates to automatic adjustment of position and orientation of a virtual character in a virtual scene of a virtual reality application. The initial position and orientation of the virtual character may be determined by sensors. The position and orientation of the virtual character may be adjusted without user action to a predetermined position and orientation for automatically triggering an event in the virtual reality application.

Method and device for determining and adjusting spatial attribute of virtual character in virtual reality applications

An integrated circuit (IC) can dynamically manage memory communication paths between multiple processors and multiple memory modules. The IC can include upstream logic that performs data conversion and provides memory communication paths between each processor and a corresponding upstream port. An interconnect layer in the IC can be electrically coupled to the upstream ports to multiple downstream ports. An interconnect management processor electrically coupled to the interconnect layer can respond to received commands by executing an allocation program stored in a read-only memory (ROM) that dynamically establishes and terminates memory communication paths between the upstream ports and the downstream ports. A memory interface layer in the IC can be electrically coupled to the downstream ports and to the memory modules, and can provide, through corresponding memory physical interfaces, memory communication paths between the multiple downstream ports and corresponding memory modules.
