  • Publication number: 20070269887
    Abstract: The invention includes compositions of stem and progenitor cells recovered from bone marrow or cord blood containing most of the viable CD34+ cells and substantially depleted of red blood cells resident in the original sample, without any xenobiotic additives to aid cell separation. The invention also includes a system and method for preparing the compositions. The system includes a bag set and a processing device, which utilizes an optical sensor, microcontroller, servo motor, accelerometer, load cell, and battery. The system and method utilize centrifugation to stratify the cells into layers and then separate and transfer the stem cells into a stem cell bag. The processing device's microcontroller receives input from the device's accelerometer, load cell and optical sensor to direct the metering valve in the bag set to open and close to permit the transfer of as many stems cells as possible with as few red cells as possible.

  • Publication number: 20070241203
    Abstract: An HVAC system comprises a programmable wireless thermostat and a remote receiver unit. The thermostat includes a user interface having one or more displays, user input devices, such as buttons, sliders, or a touch screen, and a backlight. The thermostat may include a proximity sensor, wherein the user interface is controlled based on a user's presence near the thermostat. A thermostat controller enters into a reduced energy consumption mode and switches the user interface to an idle state when the proximity sensor indicates a lack of user proximity for a predetermined duration. When the proximity sensor indicates user proximity, the controller exits the reduced energy consumption mode and switches the user interface to an active state. During the reduced energy consumption mode, the user interface may be concealed when the user interface is in a housing which is transparent when backlit but is opaque otherwise.

  • Publication number: 20070206607
    Abstract: A resource reservation and admission control scheme uses pseudowires to reserve bandwidth over a layer-2 and/or layer-3 network. The pseudowires are associated with ports on different network processing devices. During a resource reservation and admission control session, the physical links used by the pseudowire are selected and reserved to more effectively allocate network bandwidth. The negotiated pseudowire is then used to transport content for a communication session over the network. In one example application, the resource reservation and admission control scheme is used during a Downstream External PHY Interface (DEPI) session for pseudowires established between a Modular Cable Modem Termination System (M-CMTS) Core and an Edge Quadrature Amplitude Modulation Interface (EQAM) device. However, the reservation protocol can be used in any application that needs to reserve bandwidth over an Internet Protocol (IP) network.

  • Publication number: 20070200719
    Abstract: A gas detector and method of operating the gas detector that includes a carbon monoxide sensor and a processor. The carbon monoxide sensor senses an environmental concentration of carbon monoxide and provides the sensed value to the processor. Upon receiving the value of the carbon monoxide level (COppm), the processor determines an alarm threshold level based upon the COppm level. Once the alarm threshold level is determined, the processor calculates the COHb percentage for the current COppm reading based upon a derived, fixed point equation. The processor activates an audible/visual indicator when the sensed COHb percentage exceeds the alarm threshold.

  • Publication number: 20070195824
    Abstract: A modular Cable Modem Termination System (CMTS) includes a packet shelf operating a Data Over Cable Service Interface Specifications (DOCSIS) Media Access Control (MAC) framer. One or more downstream Physical Interface (PHY) shelves receive DOCSIS data from the packet shelf over a packet switched network and modulate the DOCSIS data for sending on a downstream path of a cable plant. One or more upstream PHY shelves send DOCSIS data received from an upstream path of the cable plant over the packet switched network to the packet shelf. By separating the PHY components from the MAC and from the system software, the PHY components for a Hybrid Fiber Coax (HFC) plant may be replaced with different PHY components for other access technologies such as wireless, Digital Subscriber Lines (DSL), Ethernet-to-the-Home, Fiber-to-the-Home, or fiber Passive Optical Networks (PONs).
