Patent number: 10299219Abstract: A data transfer system, a method of data transfer and a corresponding transmitter and receiver are disclosed. A communication protocol between the transmitter and receiver is defined using a set of valid transmission states for communication from the transmitter to the receiver and a set of valid acknowledgement states for transmission from the receiver to the transmitter. A Hamming distance between patterns of zeroes, and between patterns of ones, in valid states of each of these sets is at least one and the transmitter is arranged to transition between a number of transmission states in response to the reception of an acknowledgement state from the receiver which matches a transmission state it has sent to the receiver on a request bus. A communication protocol which is robust across a multi-voltage and/or clock domain interface is thus provided.Type: GrantFiled: May 27, 2016Date of Patent: May 21, 2019Assignee: ARM LimitedInventor: David Walter Flynn

Patent number: 10268098Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.Type: GrantFiled: May 11, 2018Date of Patent: April 23, 2019Assignee: View, Inc.Inventors: Dhairya Shrivastava, Anshu A.

Publication number: 20190107232Abstract: A method is provided for forming a gasket for sealing opposing flange surfaces of a pipe having corrosive fluid flowing therethrough. The method comprises defining a gasket profile incorporating a serrated profile core having a flange extending radially inward therefrom. A deformable pillow extends radially inward from the serrated profile core, to define a gasket intermediate portion about the flange, and a gasket inner portion radially inward from the flange. The deformable pillow material and thickness are selected such that upon compression to a thickness no less than the core thickness, the gasket inner portion exhibits a stress level sufficient to preclude corrosive liquid flowing through the pipe from passing radially outward beyond the gasket inner portion, and the gasket intermediate portion exhibits a stress level sufficient to preclude gas and liquid flowing through the pipe from passing radially outward beyond the gasket intermediate portion.Type: ApplicationFiled: December 7, 2018Publication date: April 11, 2019Applicant: ERIKS N.V.Inventors: Alan Stubblefield, David Walter Reeves

Patent number: 10209755Abstract: A system comprises a first domain 4 and second domain 6 which communicate via an interface 8. The first domain 4 transmits power state commands to the second domain 6 for controlling transitions of power states at the second domain 6. The power state commands include at least a power up command 50 for triggering a transition to a power up state and a power no-operation command 52 in response to which the second domain remains in the current one of the power states. The no-operation command 52 enables the second domain 6 to be left in either the power up state or a different power state even if the first domain 4 is powered down.Type: GrantFiled: January 30, 2017Date of Patent: February 19, 2019Assignee: ARM LimitedInventors: David Walter Flynn, Vasan Venkataraman

Publication number: 20190037175Abstract: A secure teleconference with a patient treatment room may be initiated by receiving, at a central facility, a request for a conference from a clinician application, and then identifying a virtual meeting room and sending an identifier for a conference to the treatment room. The conference is then be established by receiving a call at the central facility from the treatment room, where the call identifies the conference. The central facility then joins the treatment room and the clinician application to the virtual meeting room. Teleconferences may thus be established without reference to sensitive patient information. For security, no incoming conferencing calls may be made to the treatment room directly, and virtual meeting rooms may be eliminated after single use. A call may further be initiated by receiving a request from the treatment room, e.g., which is processed by the central facility to alert one or more clinicians.Type: ApplicationFiled: July 26, 2018Publication date: January 31, 2019Inventors: John Mitchell Vitale, David Walter Galas, Jennifer R.
