  • Publication number: 20260022846
    Abstract: A low-profile window-mountable air conditioning-heating system, described herein, comprises an air conditioning-heating unit formed by interior and exterior housings and interconnected by a bridge housing that encloses flexible fluid lines and sliding bridge rails. The system also comprises a mounting frame that supports the unit across a building wall without permanent attachment or wall penetration. The frame also enables pivoting and extension to simplify installation and accommodate different wall thicknesses. The system comprises a window-frame seal with a center seal module and stackable seal modules to accommodate varying window widths. The center seal module comprises a rigid base configured to interlock with other bases thereby filling the gap in different window sizes while enhancing thermal insulation, water resistance, and durability. The modular aspect of the window-frame seal provides improved weather sealing, simplifies installation, and avoids the limitations of conventional seals.

  • Publication number: 20190113035
    Abstract: The present teachings include an energy recovery device usable in multiple applications, for example hydropower and vehicle power plant applications. In one aspect, an energy recovery device includes a housing having an inlet and an outlet in fluid communication with an internal cavity, and a pair of counter-rotating rotors having intermeshed lobes disposed within the housing internal cavity. Each rotor defines a transport volume between the housing and a pair of adjacent lobes and has a calculated maximum ideal twist angle below which the transport volume will be sealed from both the housing inlet and housing outlet. Each rotor also has an actual twist angle that exceeds the maximum ideal twist angle.

  • Patent number: 8209960
    Abstract: A diesel exhaust aftertreatment system comprises an LNT within an exhaust line. A low thermal mass DPF and a low thermal mass fuel reformer are configured within the exhaust line upstream from the LNT. A thermal mass is configured downstream from the fuel reformer and the DPF, but upstream from the LNT. For LNT denitration, the fuel reformer is rapidly heated and then used to catalyze steam reforming. The DPF is also rapidly heat each time the fuel reformer is heated and the LNT denitrated. The system operates to regenerate the DPF each time the LNT is denitrated. Preferably, a second DPF is provided to augment the performance of the first DPF. Preferably, the first DPF is small and of the flow through type whereas the second DPF is much larger and of the wall flow filter type. The second DPF can be used as the thermal mass.

  • Patent number: 8073930
    Abstract: The present invention provides an assistive technology screen reader in a distributed network computer system. The screen reader, on a server computer system, receives display information output from one or more applications. The screen reader converts the text and symbolic content of the display information into a performant format for transmission across a network. The screen reader, on a client computer system, receives the performant format. The received performant format is converted to a device type file, by the screen reader. The screen reader then presents the device type file to a device driver, for output to a speaker, braille reader, or the like.

  • Patent number: 7975489
    Abstract: According to one aspect, a method of detecting catalyst module overheating in a catalytic combustion system is provided. In one example, the method includes detecting one or more signals from at least one probe adapted to obtain values associated with at least one of the outlet gas temperature of a catalyst module and the outlet face temperature of the catalyst module included in a catalytic combustor. The one or more signals are compared with a preselected value associated with catalyst overheating. The detected temperature may be detected over time to determine a rate of change in the temperature. The temperature may be detected with a UV sensor directed to the catalyst outlet face.

  • Patent number: 7693732
    Abstract: The present invention provides a computer implemented lab reservation system including a reservation engine and a reservation database. The reservation database contains data concerning the computer systems and target operating environments in the lab. The reservation engine manipulates the reservation database in order to efficiently match user requests to specific lab computer systems and target operating environments. The reservation system also manipulates the reservation database in order to efficiently configure computer systems and target operating environments. The reservation engine also manipulates the reservation database in order to efficiently reinstall computer system default settings, when users return configured systems, so that the computer systems can be reallocated to new requests.

  • Publication number: 20050104575
    Abstract: An electric power meter (102) includes a temperature sensor (114) and a controller (112). The controller (112) is operable, based on the temperature reported from the temperature sensor (114), to generate alarm(s) when the temperature exceeds certain alarm threshold(s) (307, 507, 508) and to activate a power disconnect switch (104), thereby shutting off power to a customer premises, when the temperature exceeds a shut off threshold (309, 509). The controller (112) is operable to activate the power disconnect switch (104) for non-payment of electricity cost, subject to secondary criteria based on regulatory requirements. A customer terminal (103) may be used to notify a customer of an alarm condition, to provide information regarding electrical power usage or to provide information regarding disconnection of electrical power.
