20140130801 | ELECTRONIC FLUID FLOW CONTROLS WITH INTEGRATED MANUAL FLUID FLOW CONTROLS - In various embodiments, a flow selector of a fluid flow control system may be used to select a flow rate of a fluid. When the system is in an electronic mode, an encoder may electronically encode the fluid flow selection. A controller may receive the electronically encoded flow selection and transmit a corresponding control signal to an electronic valve to allow the fluid to flow at the selected flow rate. An engagement device, such as a clutch, may disengage the flow selector from a mechanical valve when the fluid flow control system enters a manual mode. When the system is in a manual mode, the engagement device may engage the flow selector with the mechanical valve, allowing the flow selector to directly control the flow rate of the fluid through the mechanical valve. Applications to gases and anesthesia delivery are disclosed herein. Various alternative components and embodiments are described herein. | 05-15-2014 |
20140130880 | ELECTRONIC AND MANUAL BACKUP FLOW CONTROL SYSTEMS - In various embodiments, an electronic flow selector of a fluid flow control system may be used to select a flow rate of a fluid. When the system is in an electronic mode, an encoder may electronically encode the fluid flow selection. A controller may receive the electronically encoded flow selection and transmit a corresponding control signal to an electronic valve to allow the fluid to flow at the selected flow rate. When the system is in a manual mode, backup manual flow selectors may be used to directly control the flow rate of a fluid. When the system is in a manual mode, the mechanical backup flow selectors may be in a deployed position. When the system is in an electronic mode, the mechanical backup flow selectors may be in a retracted position. Particular applications to gases and anesthesia delivery are disclosed herein. | 05-15-2014 |

20140190480 | MULTI-VAPORIZER INTERLOCK SYSTEM - One or more anesthetic vaporizers may be fluidly connected to the anesthetic delivery machine via a vaporizer mounting bar. The vaporizer mounting bar may include multiple vaporizer mounting positions. Each vaporizer includes interlock pins that extend when the vaporizer is opened and prevent the vaporizer from being opened when pushed in. When a first vaporizer is opened, its interlock pins may extend and cause the interlock pins of adjacent vaporizers, and vaporizers within a chain of interlock pin connections, to be pushed in, preventing the other vaporizers from being opened simultaneously with the first vaporizer. In various embodiments, a paddle system may translate the extension of an interlock pin from one vaporizer to the interlock pins of each of the other vaporizers in the direction of the extension, including the interlock pins of vaporizers in non-adjacent and non-chain positions. | 07-10-2014 |

20120069135 | SYSTEMS AND METHODS FOR ERROR RESILIENCE AND RANDOM ACCESS IN VIDEO COMMUNICATION SYSTEMS - Systems and methods for error resilient transmission and for random access in video communication systems are provided. The video communication systems are based on single-layer, scalable video, or simulcast video coding with temporal scalability, which may be used in video communication systems. A set of video frames or pictures in a video signal transmission is designated for reliable or guaranteed delivery to receivers using secure or high reliability links, or by retransmission techniques. The reliably-delivered video frames are used as reference pictures for resynchronization of receivers with the transmitted video signal after error incidence and for random access. | 03-22-2012 |
20120072499 | SYSTEM AND METHOD FOR THE CONTROL AND MANAGEMENT OF MULTIPOINT CONFERENCE - Systems and methods for the control and management of multipoint conferences are disclosed herein, where endpoints can selectively and individually manage the streams that will be transmitted to them. Techniques are described that allow a transmitting endpoint to collect information from other receiving endpoints, or aggregated such information from servers, and process them into a single set of operating parameters that it then uses for its operation. Algorithms are described for performing conference-level show, on-demand show, show parameter aggregation and propagation, propagation of notifications. Parameters identified for describing sources in show requests include bit rate, window size, pixel rate, and frames per second. | 03-22-2012 |
20120192240 | PARTICIPANT AWARE CONFIGURATION FOR VIDEO ENCODER - Systems and methods for multipoint video distribution are disclosed herein. In some embodiments, system for multipoint video distribution include at least one endpoint including a EECM and a DECM, and at least one server including a SECM, the server being coupled to the endpoint. In some embodiments, methods for configuring an encoder include receiving at least one property related to a capability of a decoder, determining a number of layers to be coded by the encoder, and configuring the encoder based on that at least one property. | 07-26-2012 |
20120230429 | RENDER-ORIENTATION INFORMATION IN VIDEO BITSTREAM - Disclosed are techniques for creating, coding, decoding, and using, rotation information related to one or more coded pictures in non-normative parts of a coded video bitstream. | 09-13-2012 |
