  • Method for operating gas generators in tandem
    Patent number: 7445660
    Abstract: A gas generating system (S) has a plurality of product gas generating modules (18) each of which comprises a plurality of molecular sieve beds (bed 1, bed 2) generating a product gas acting in a repetitive cycle with each cycle having a period of the cycle with peak product gas flow (106). A manifold (52) combines the product gas from the plurality of modules (18). The processor (58) generates a control signal that is communicated to the gas generating modules (18) such that the peak product gas flow period (106) of the repetitive cycle of the modules (18) is adjusted in response to the control signal. The processor (58) causes the peak period (106) for the modules (18) to be timed across the repetitive cycles in a controlled distribution.

  • Processing spoken commands to control distributed audio outputs
    Patent number: 10262657
    Abstract: A system that is capable of controlling multiple entertainment systems and/or speakers using voice commands. The system receives voice commands and may determine audio sources and speakers indicated by the voice commands. The system may generate audio data from the audio sources and may send the audio data to the speakers using multiple interfaces. For example, the system may send the audio data directly to the speakers using a network address, may send the audio data to the speakers via a voice-enabled device or may send the audio data to the speakers via a speaker controller. The system may generate output zones including multiple speakers and may associate input devices with speakers within the output zones. For example, the system may receive a voice command from an input device in an output zone and may reduce output audio generated by speakers in the output zone.

  • SEAMLESS ROAMING FOR MULTI-LINK DEVICE CLIENTS
    Publication number: 20230094149
    Abstract: Seamless client roaming for Multi-Link Device (MLD) clients may be provided. First, a Traffic Identifier (TID)-to-link map may be established by an Upper Service Access Point (U-SAP) of a multi-AP MLD entity that assigns subsets of TIDs to at least two links of the entity. For example, a client device logically associates with the U-SAP, while the client device physically connects to a first and second AP of the entity on a respective first and second link, where the first and second AP include first and second Lower Service Access Points (L-SAPs) and are non-collocated. Next, using the map, data received at the U-SAP is directed over one of the two links for transmission to the client device. Further, frame aggregation and block acknowledgment functions may be performed by one of the first or second L-SAP based on whether data transmission is over the first or second link.

  • Apparatus for restraining over-eager load boosting in an out-of-order machine using a memory disambiguation buffer for determining dependencies
    Patent number: 6006326
    Abstract: A system for restraining over-eager boosting of load instructions past store instructions in an out-of-order processor. The system comprises a memory disambiguation buffer for storing load and store instruction addresses and associated data and an instruction scheduling window in operative association with the memory disambiguation buffer. The instruction scheduling window and the memory disambiguation buffer determine load/store dependencies and effectuate replay of the store and load instructions wherein a dependent load instruction has been executed prior to a store instruction. An instruction cache is provided in operative association with the memory disambiguation buffer, together to associate the dependent load instructions with a store instruction such that the store instruction is subsequently executed prior to the dependent load instructions.

  • Portable cylinder contribution tester for a vehicle which includes a diesel engine which is controlled by an electronic circuit
    Patent number: 5987974
    Abstract: The present invention provides a portable cylinder contribution tester for an electronic diesel engine, the diesel engine including a plurality of cylinders. The tester comprises a plurality of switches, each of the plurality of switches coupled to and for controlling one of the plurality of cylinders and a case for mounting the plurality of switches. When an abnormal diesel engine operation is detected each of the plurality of switches can be activated. When one of the plurality of switches is activated and the diesel engine does not decrease in performance it is indicated that the associated cylinder is malfunctioning. Existing test equipment for most electronic diesel engines is PC based and available to franchised dealers only, as well as not being portable for drive testing. Through the use of a cylinder contribution tester in accordance with the present invention, these type of repairs could be available to many independently owned non-franchised facilities.

  • Oxygen generator with storage and conservation modes
    Patent number: 7694674
    Abstract: An electronic controller (16) controls the operation of an electrochemical oxygen generating system (14) producing a desired gas. The product gas is fed to a storage unit (12) or a regulator (28) and pulsing valve (28) controlling the gas flow to a user. A two-stage system (180) combines a low pressure 100 and a high pressure (150) gas generating subsystems. The low pressure subsystem (100) uses IMAT's (106) to pump oxygen from ambient air to generate a low-pressure. The high pressure subsystem (150) uses IMAT's (160) to pump oxygen to high-pressure oxygen storage devices (194).

  • Mobile sludge trailer and method of filling and emptying same
    Patent number: 4082672
    Abstract: A novel trailer is described which is particularly well-suited for receiving, transporting and unloading sludges which range in consistency from nearly liquid to semi-solid or otherwise extremely viscous materials. The novel trailer of the present invention is adapted to selectively promote aerobic or anaerobic digestion of the sludges contained therein by utilizing a novel pressure equalization system and other means. Further, the pressure of gases, particularly methane gas, which is produced as a result of said digestion is harnessed in part to facilitate the easy unloading of sludge from the trailer. Additionally, auxiliary pressurization means is provided to pressurize the head space within said tank during unloading, while a novel ejection means is disposed adjacent to or within the discharge opening which will supply, if desired, an aerated product under pressure for transfer to adjacent facilities without additional pumping.

  • METHOD AND SYSTEM FOR MONITORING EMAIL AND WEBSITE BEHAVIOR OF AN EMAIL RECIPIENT
    Publication number: 20070005762
    Abstract: A system for monitoring email and website behavior of an email recipient is provided. According to one exemplary embodiment, the system includes a mail enhancement server and a logging server. The mail enhancement server is configured to intercept all outgoing emails from a mail server. The mail enhancement server then modifies each outgoing email to include a tracking code. The tracking code is embedded in an image call which in turn is also inserted into the outgoing email. If the outgoing email contains hyperlinks, each hyperlink is also modified to include the tracking code. The tracking code is uniquely associated with the outgoing email. The image call (and the tracking code) is used to detect when the recipient of the outgoing email has opened that email. The tracking code, when embedded in a hyperlink, is also used to monitor whether the recipient has opened the email and/or clicked through on one or more of the hyperlinks in the email.
