Patent number: 11941311Abstract: In one example, a system can receive an order from a client device. The system can also receive data about a set of print queues at a set of printers via a network. The system can then determine a set of queue times corresponding to the set of print queues. Each respective queue time can be determined based on a corresponding print queue. The system can generate an estimated wait time for the order based on the set of queue times. The system can then transmit the estimated wait time to the client device for display in a graphical user interface to a user associated with the order.Type: GrantFiled: August 7, 2023Date of Patent: March 26, 2024Assignee: Starbucks CorporationInventors: Harsh Nigam, Michael J.

Patent number: 10337747Abstract: A furnace controller for a modulating furnace that helps provide a balance between energy efficiency and occupant comfort across various burner firing rates and/or across various circulating blower speeds. In some cases, the furnace controller can be configured to permit a user to customize operation of the furnace in accordance with their particular needs and/or desires with respect to efficiency and comfort. A selection may be made between an energy efficiency setting and a user comfort setting. Then, a plenum parameter such as a discharge air temperature (DAT) or discharge air flow (DAF) may be regulated in accordance with the selected setting.Type: GrantFiled: March 30, 2016Date of Patent: July 2, 2019Assignee: Ademco Inc.Inventors: Timothy J. Nordberg, Brent Chian, Douglas D. Bird, Michael W. Schultz, Peter M. Anderson

Patent number: 8919337Abstract: A system having a pre-mix burner manifold in a housing that may permit air to be drawn through slots in the housing to flow over an external surface of the manifold. The flow of air may maintain a temperature of the manifold lower than a temperature that the manifold might have without the flow. The manifold may be attached to a burner and heat exchanger.Type: GrantFiled: June 21, 2012Date of Patent: December 30, 2014Assignee: Honeywell International Inc.Inventors: Michael W.

Patent number: 8635997Abstract: Systems and methods for controlling gas to gas-fired appliances are disclosed. An illustrative system can include a modulating gas valve adapted to supply gas to a burner unit, an inducer fan adapted to produce a combustion air flow at the burner unit, a pressure reducing element in fluid communication with the gas valve and adapted to output at least one pressure signal for sensing the combustion air flow outputted by the inducer fan, and a controller for controlling the speed of the inducer fan. The pressure reducing element can include a venturi tube, flow nozzle, or other suitable device capable of producing pneumatic signals that can be used by the gas valve to modulate the gas supplied to the burner unit. By pneumatically linking the gas valve to the actual combustion air flow, the gas valve can be operated over a wide range of firing rates by adjusting the speed of the inducer fan.Type: GrantFiled: October 18, 2006Date of Patent: January 28, 2014Assignee: Honeywell International Inc.Inventors: Michael W. Schultz, Glenn R. Bergum

Patent number: 8591221Abstract: A forced air furnace may include a pneumatically modulated gas valve that is configured to provide gas to a burner. A pneumatic sampling device may be disposed proximate a combustion blower and may be configured to provide the pneumatically modulated gas valve with a first pneumatic signal and a second pneumatic signal that are representative of fluid flow through the pneumatic sampling device. The pneumatically modulated gas valve may regulate gas flow in accordance with the first and second pneumatic signals. In some cases, the pneumatic sampling device may include a restriction, a first pressure port disposed upstream of the restriction and a second pressure port disposed downstream of the restriction. The first and second pressure ports may provide the first and second pneumatic signals to the pneumatically modulated gas valve.Type: GrantFiled: May 19, 2008Date of Patent: November 26, 2013Inventor: Michael W.
