  • Publication number: 20190262201
    Abstract: A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

  • Patent number: 7639134
    Abstract: An identification device establishes a relative hierarchy of associated containers as logistical units, providing multi-layer visibility of nested and adjacent containers. The relative hierarchy comprises lower-layer containers and upper-layer containers relative to the identification device. An integrated reader device reads heterogeneous tag types. This allows disparate tag types simultaneously using a single device.

  • Patent number: 7382264
    Abstract: A system federates heterogeneous monitoring systems to provide end-to-end monitoring information for conveyances with item-layer visibility. A first node of the federated system comprises a first monitoring system and a first port and a second node comprises a second monitoring system and a second port. In parallel with a conveyance being transported between the first node and the second node, the first monitoring system sends an agent to the second monitoring system. The agent comprises logic and/or data necessary to implement processes on the second monitoring agent while the conveyance is at the second port. When the conveyance arrives at the second port, the second monitoring system executes the agent to determine conditions of the conveyance and/or its contents.

  • Patent number: 7307536
    Abstract: Systems and methods to provide multi-layer visibility of nested containers at a mobile checkpoint are disclosed. Thee systems include a portable deployment kit in communication with a nested container. The portable deployment kit can be contained in a durable carrying case having a total weight that is within military standards for carrying by one person and includes a handle. Inside, the carrying case can include foam or other material to protect internal components during transport and deployment. In use within the system, the portable deployment kit can serve as a self-contained checkpoint or site server for gathering necessary information from the nested container and uplinking for centralized data collection. In one embodiment, the portable deployment kit includes a label printer for updating an identification device on the nested container to reflect, for example, aggregation and deaggregation.

  • Patent number: 7196622
    Abstract: A container for locally determining a container state using a state device. The state device detects unexpected events by comparing expected event information with actual event information related to a container condition. The container condition includes, for example, environmental conditions, logistical or location conditions, and physical or security conditions. Thus, the container is able to intelligently monitor its state and raise an alert without intervention from a central system. The container can also be programmed and reprogrammed with updated logic, states, and/or expected event information. A sensor in the state device gathers input information for comparison to expected event information. A communication port in the state device receives event information. For example, a GPS (Global Positioning System) receiver can determine a current location for comparison to an expected location at the current time.

  • Patent number: 7173530
    Abstract: A nested container establishes a relative hierarchy of associated containers as logistical units. The relative hierarchy comprises lower-layer containers and upper-layer containers relative to the nested container. To do so, the nested container sends interrogation signals to neighboring containers in order to retrieve identification information and layer information. Also, the nested container sends its own information identification information and layer information responsive to received interrogation signals. The nested container outputs the relative hierarchy to, for example, a site server or agent using a hand-held device. The identification module comprises, for example, an RFID (Radio Frequency IDentification) device.

  • Patent number: 7129837
    Abstract: A control center continuously monitors a security state of a container through an extended network spanning from a shipper to a consignee. The control center changes the security state responsive to explicit information received from a trusted agent, or implicit information deducted from business logic. A trusted shipper agent sends manifest information from a shipper checkpoint to the data center that includes, for example, container information, shipping route information, and other security information. Trusted monitor agents continuously track the security state from the shipper checkpoint to the origin checkpoint, from the origin checkpoint to a destination checkpoint, and from the destination checkpoint to a consignee checkpoint. A trusted consignee agent sends termination information from the consignee checkpoint to the data center.
