Publication number: 20240111504Abstract: A method for generation of chat applications includes receiving a deployment request requesting deployment of a no-code application generated by a user within a no-code environment to a chat application environment. The no-code application includes a trigger condition, an action response defining an action in response to the trigger condition being satisfied, and a no-code environment graphical user interface (GUI) view based on the action response. The method includes, after receiving the deployment request, receiving an interaction indication indicating that the trigger condition is satisfied. In response to receiving the interaction indication, the method includes executing the action response, translating the no-code environment GUI view into a chat application GUI view, and transmitting the chat application GUI view to a user device. The chat application GUI view is configured to cause the user device to display the chat application GUI view within the chat application environment.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Applicant: Google LLCInventors: Michael Jeffrey Procopio, Sarmad Hashmi, Rachel Goodman Moore, Nicholas Eric Westbury, Girimurugan Natarajan, Francis Herrera Cortez, Carlin Yuen

Patent number: 11946033Abstract: A micro alternating tangential flow (microATF) perfusion filter includes a hollow cylinder having a proximal end and a distal end. The proximal end is connected in series to a permeate chamber, followed by a retentate chamber. The proximal end either (i) terminates in or at the permeate chamber, or (ii) terminates in or at the retentate chamber. The portion of the proximal end within the permeate chamber, in a case of (ii), possesses at least one opening allowing fluid communication between an inside of the hollow cylinder and the permeate chamber. The microATF perfusion filter further includes an inlet, positioned over the retentate chamber, for communication with a source of positive or negative pressure, and an outlet, positioned in a wall of the permeate chamber, which can be connected to a check valve, which, in turn, can be connected to a hydrophobic fluid vent filter.Type: GrantFiled: April 26, 2022Date of Patent: April 2, 2024Assignee: REPLIGEN CORPORATIONInventors: Michael Bransby, Philip Yuen

Patent number: 7813370Abstract: Migrating from a legacy spectrum allocation to a target spectrum allocation can be accomplished by adding new access points and, at a selected time, activating the new access points and deactivating the legacy access points with a remote network manager. Alternatively, the new access points can initially support legacy channels and at a selected time be reconfigured to support only the target channels. Alternatively, the new access points are initially activated in a mode which supports only a subset of the target channels and at a selected time reconfigured to support only the target channels. A remote network manager may be employed to remotely monitor, reconfigure, and trigger activation and deactivation of access points in support of the technique. New access points adapted to respond to inputs from the remote network manager further facilitate the invention.Type: GrantFiled: April 25, 2005Date of Patent: October 12, 2010Assignee: Autocell Laboratories, Inc.Inventors: Roger Durand, Michael Yuen

Patent number: 7636550Abstract: A system and method for Access Point (AP) channel selection based upon a Channel Quality Index (CQI) is described. The Channel Quality Index (CQI) is a value which quantifies a transmission quality of a channel. The transmission quality is evaluated based on a combination of different types of measured interference in the channel. In one embodiment the different types of measured interference include co-channel congestion, adjacent channel interference and in-band interference. The CQI is a value derived from the measurements, and for example may be a sum of all of the measurements.Type: GrantFiled: June 23, 2005Date of Patent: December 22, 2009Assignee: Autocell Laboratories, Inc.Inventors: Michael Yuen, David Hill, Roger Durand

In one embodiment the different types of measured interference include co-channel congestion, adjacent channel interference and in-band interference. The CQI is a value derived from the measurements, and for example may be a sum of all of the measurements. Each AP of the present invention determines the CQI of potential transmission channels, and selects a channel for use which has the ‘best’ CQI; for example if the CQI is a sum of all measured interferences, the ‘best’ AP is the one with the lowest CQI.Type: GrantFiled: June 23, 2005Date of Patent: December 15, 2009Assignee: Autocell Laboratories, Inc.Inventors: Michael Yuen, David Hill, Roger Durand

Publication number: 20070097940Abstract: A pre-scan interval including three states is employed to synchronize access points and facilitate power control to facilitate initial channel selection where a group of nearby access point are contemporaneously initialized. In State 1 the access point is operable to transmit pre-scan frames which include device ID, and to listen for pre-scan frames transmitted by other access points. When a pre-scan frame is received, the received power level and device ID are noted and used to construct a table. The access point normally remains in State 1 until a minimum number of frame samples have been received from each access point that has been heard, and a minimum pre-scan time has elapsed. State 2 provides synchronization of transition of the access points between State 1 and State 3. When the access point is in State 2, it transmits pre-scan frames with a sync-mark bit set to indicate that the access point is in State 2.Type: ApplicationFiled: November 3, 2006Publication date: May 3, 2007Inventor: Michael Yuen

Patent number: 7139250Abstract: A port on a network device engages in auto-negotiation on a network link during a first operational state to select a transmission mode, either half duplex or full duplex. If half duplex operation is selected, the port commences half duplex operation in a second operational state. During the second operational state, the link is monitored for an error condition indicating that another network device attached to the link may not be operating in a half duplex mode. This error condition includes the occurrence of excessive collisions or late collisions. When the error condition is detected, the port commences full duplex operation in a third operational state, based on the presumption that device at the other end of the link may be configured for fixed full duplex operation. If proper operation ensues, the port remains configured for full duplex transmission.Type: GrantFiled: April 30, 2003Date of Patent: November 21, 2006Assignee: 3Com CorporationInventors: Steven Lyle Gardner, James Scott Hiscock, Michael Yuen
