Patent number: 11735680Abstract: A transmit integrated circuit includes a light source configured to generate a beam of light. A receive integrated circuit includes a first photosensor. A transmit optic is mounted over the transmit and receive integrated circuits. The transmit optic is formed by a prismatic light guide and is configured to receive the beam of light. An annular body region of the transmit optic surrounds a central opening which is aligned with the first photosensor. The annular body region includes a first reflective surface defining the central opening and further includes a ring-shaped light output surface surrounding the central opening. Light is output from the ring-shaped light output surface in response to light which propagates within the prismatic light guide in response to the received beam of light and which reflects off the first reflective surface.Type: GrantFiled: February 10, 2021Date of Patent: August 22, 2023Assignee: STMicroelectronics (Research & Development) LimitedInventors: Thineshwaran Gopal Krishnan, Roy Duffy

Patent number: 10628330Abstract: A method is described for enabling inter-process communication between a first application and a second application, the first application running within a first virtual machine (VM) in a host and the second application running within a second VM in the host, The method includes receiving a request to attach a shared region of memory to a memory allocation, identifying a list of one or more physical memory pages defining the shared region that corresponds to the handle, and mapping guest memory pages corresponding to the allocation to the physical memory pages. The request may be received by a framework from the second application and includes a handle that uniquely identifies the shared region of memory as well as an identification of at least one guest memory page corresponding to the memory allocation.Type: GrantFiled: April 6, 2018Date of Patent: April 21, 2020Assignee: VMware, Inc.Inventors: Gustav Seth Wibling, Jagannath Gopal Krishnan
