  • Patent number: 11441315
    Abstract: In a first aspect, a system for heating, cooling, or both heating and cooling a room is disclosed. The system includes a panel with a first, second, and third wall. The second wall is disposed between the first and third walls and separated by a plurality of partitions. The partitions create a first and second row of elongated channels. Each channel in the first row is bounded on two sides by two partitions and on two other sides by the first and second walls. Each channel in the second row is bounded on two sides by two partitions and on two other sides by the second and third walls. The first row of channels is a fluid layer configured to allow heated or cooled fluid to pass through. The fluid layer is in thermal communication with the room. The second row of channels is an insulating vacuum layer, with a reduced pressure that is at least 20% less than atmospheric pressure.

  • Publication number: 20220041169
    Abstract: A method of providing an indication of driving performance involves obtaining a forward acceleration and speed of a vehicle. A forward acceleration threshold value is identified for use in identifying excessive forward acceleration of the vehicle based on the determined speed of the vehicle. For any vehicle speed within a range of vehicle speeds, the acceleration threshold value is defined by a function based on the determined speed of the vehicle, wherein the forward acceleration threshold value according to the function varies continually with vehicle speed over the range of vehicle speeds. The determined forward acceleration of the vehicle is compared with the determined acceleration threshold value, and an indication of an excessive forward acceleration driving event is generated when the determined forward acceleration exceeds the determined acceleration threshold value.

  • Publication number: 20210148586
    Abstract: The invention is, in one aspect, a system for heating or cooling a room, including a radiant panel with fluid conduit, which, radiates energy to a room. A heat exchange device exchanges energy between the fluid in the radiant panel and an exchange medium. A vent allows fresh air to enter a room, moved by a fan. The fan propels the air through a chamber for heating or cooling the air, wherein the chamber at least partially comprises the radiant panel.

  • Publication number: 20210120635
    Abstract: The invention is a heating and display mirror. The mirror is composed of two different “zones”, one for heating and one for display. The heating zone is heated by radiant heat, and the display zone features a display device that produces lighted images visible on the mirror's surface. The heating and display zones are operated by user controls, which give instructions to the heating zone to turn on and off, and to the display zone regarding what images to display on the lighted display device.

  • Publication number: 20210102717
    Abstract: An apparatus for heating or cooling a room of a building with an exterior wall includes a radiant panel supported on an exterior wall, which includes a fluid conduit for passage of a fluid. The fluid enters through an inlet and exits through an outlet of the radiant panel and goes through a transmission tube and into a heat exchanger, which is located on the exterior side of the wall. The fluid then flows through the transmission tube and enters the inlet of the radiant panel.

  • Patent number: 10922646
    Abstract: Features related to systems and methods for predictive estimation for network inventory planning for items for distribution through a multi-echelon network are disclosed. The problem may be modeled to account for demand for an item that may be satisfied by fulfillment centers within the network. The model considers benefits to ensuring adequate inventory to meet expected demand streams along with any savings accruing from a lower transfer and salvage costs.

  • Patent number: 9805402
    Abstract: Techniques for determining a decision to acquire units of an item to be inventoried may be provided. For example, a demand for an item may be simulated to determine a consumption of a capacity for inventorying the item. A discrepancy between the consumption of the capacity and the capacity may be determined. An opportunity cost associated with the capacity may be updated based at least in part on determining that the discrepancy fails a convergence criterion. The opportunity cost may indicate a value associated with using the capacity. The consumption of the capacity may be simulated based at least in part on the updated opportunity cost. A resulting discrepancy may be determined. If the resulting discrepancy meets the convergence criterion, the decision to acquire the units of the item may be generated based at least in part on the updated opportunity cost.
