Abstract:
A pad of a plurality of sheets of expandable slit paper is provided in which the paper expands in thickness when stretched to form expanded cells, wherein the sheets of expandable slit paper are bound together along a single edge and otherwise unbound together. In some embodiments, sheets of slit sheet material are removable for use of the slit sheet material for packing items or the like with the slit sheet material in an expanded state.

Abstract:
In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.
Abstract:
An expansion device includes an unexpanded slit sheet roil that is wound on a paper core that is longer than the width of the silt sheet paper roil, The paper core is placed onto a rod member. An adjustable downward pressure is exerted on the paper core and the paper core exerts pressure on the rod member. As the paper is pulled, the downward pressure creates the friction required to enable the unexpanded slit sheet to be unwind and fed while simultaneously expanding.
Abstract:
The preferred embodiments of the present invention provide two advantageous features, which are especially beneficial in combination, but which can be advantageously and beneficially employed independently of one another: (1) firstly, a self-cooling motor bearing system; and (2) secondly, a self- lubricating motor bearing system. In the preferred embodiments, one or both of these two advantageous features are integrated inside an electric motor (e.g., within the electric motor's enclosure housing) in such a manner as to greatly enhance bearing operating conditions (e.g., maintaining adequate bearing lubrication and/ or bearing operating temperature) without the use of external lubrication units and/ or external cooling units.
Abstract:
An integrated circuit, such as included as a portion of a sensor node, can include a regulator circuit having an input coupleable to an energy harvesting transducer. The integrated circuit can include a wireless receiver circuit coupled to the regulator circuit and configured to wirelessly receive at least enough operating energy to establish operation of the sensor node without requiring the energy harvesting transducer. The integrated circuit can include a digital processor circuit coupled to the regulator circuit and a power management processor circuit. The digital processor circuit or one or more other circuits can include a subthreshold operational mode established by the power management processor circuit based on the selected energy consumption level. For example, establishing the subthreshold operational mode can include adjusting or selecting a supply voltage so as to establish subthreshold operation of a field effect transistor (FET) in the digital processor circuit or other circuits.
Abstract:
A media-independent handover (MIH) environment supports a MIH function that uses a mapping table to communicate with other MIH functions using a MIH transport protocol. The MIH function updates the mapping table upon receipt of a message having fields to invoke an operation. The operation can update an existing mapping or delete a mapping. The operation also can update a lifetime value for a mapping for a particular address. The mapping table includes mappings. A mapping includes a MIH function identifier, a list of transport addresses, and a lifetime value.
Abstract:
A method of employing an encoding scheme for media independent handover, comprising: having at least some data type carry only required information to determine the end of data without a length value.
Abstract:
A media-independent handover key management architecture is disclosed that uses Kerberos for secure key distribution among a server, an authenticator, and a mobile node. In the preferred embodiments, signaling for key distribution is based on re-keying and is decoupled from re-authentication that requires EAP (Extensible Authentication Protocol) and AAA (Authentication, Authorization and Accounting) signaling similar to initial network access authentication. In this framework, the mobile node is able to obtain master session keys required for dynamically establishing the security associations with a set of authenticators without communicating with them before handover. By separating re-key operation from re-authentication, the proposed architecture is more optimized for a proactive mode of operation. It can also be optimized for reactive mode of operation by reversing the key distribution roles between the mobile node and the target access node.
