Abstract:
A method and a device for controlling battery heating is disclosed. The method comprises: starting battery heating when conditions for starting battery heating are met; and stopping battery heating when conditions for stopping battery heating are met. The conditions for stopping battery heating include at least one of the following: (a) an absorbed energy Q of the battery reaching a predetermined energy QSET; (b) a time period Ti during which a discharging current I of the battery maintains constant (c) the discharging current I starting to decrease when a predetermined time period TSET is reached; and (d) a heating time period T reaching a predetermined maximum heating time period Tmax. The method and the device consider multiple conditions, for example, temperature, discharging current, battery State-of-Charge, heating time, etc. to determine when to stop battery heating, which may further enhance the operating efficiency and lifespan of the battery.

Abstract:
In a method of making a polymer structure on a substrate a layer of a first polymer, having a horizontal top surface, is applied to a surface of the substrate. An area of the top surface of the polymer is manipulated to create an uneven feature that is plasma etched to remove a first portion from the layer of the first polymer thereby leaving the polymer structure extending therefrom. A light emitting structure includes a conductive substrate from which an elongated nanostructure of a first polymer extends. A second polymer coating is disposed about the nanostructure and includes a second polymer, which includes a material such that a band gap exists between the second polymer coating and the elongated nanostructure. A conductive material coats the second polymer coating. The light emitting structure emits light when a voltage is applied between the conductive substrate and the conductive coating.
Abstract:
A method and apparatus for enabling a user to access a service provider is described. The user sends a request from a browser to a proxy server. The proxy server modifies the request by adding data (such as a URL) relating to a location of an identity provider able to provide user credentials for the user and forwards the modified request to the service provider. The modification of the access request may occur before the request is sent to the service provider or in response to an authentication request from the service provider. The data relating to the location of the identity provider may be provided as a header (e.g. an http header).
Abstract:
A plate mounted fuel assembly hold-down system that provides a defined channel for both the insertion and removal of reactor head mounted, fixed in-core detector instrumentation, provides a guided path for the fixed in-core detector during insertion, and shields the instrument shroud against coolant cross flow. The hold-down assembly includes a base plate that seats on the adapter plate of the fuel assembly and has openings that align with the control rod guide thimbles. A hollow sleeve extends through and below a central opening in the base plate to mate with the fuel assembly instrument thimble. The sleeve extends above the base plate and through and above an upper core plate of the reactor. A hold-down bar is slidably mounted on the sleeve and is restrained below the top of the sleeve. A spring is positioned around the sleeve and is captured between the hold-down bar and the base plate.
Abstract:
A method for reversibly, or irreversibly, altering the permeability of cells, tissues or other biological barriers, to molecules to be transported into or through these materials, through the application of acoustic energy, is provided. The acoustic energy is applied indirectly to the cells or tissue whose permeability is to be altered, at a frequency and intensity appropriate to alter the permeability to achieve the desired effect, such as the transport of endogenous or exogenous molecules and/or fluid, for drug delivery, measurement of analyte, removal of fluid, alteration of cell or tissue viability or alteration of structure of materials. In the preferred embodiment, the method includes applying the ultrasound in combination with devices for monitoring and/or implementing feedback controls.
Abstract:
The present invention proposes a method for scheduling resource in a packet network and a network element for exchanging signaling with user equipments, wherein user equipments communicate therebetween using the resource allocated by network elements, said communication comprises talk-spurt periods during which data packets are transmitted and silent periods during which silence descriptor packets are transmitted, said method for scheduling resource comprising: said network element allocates resource for said user equipments for communication; both said user equipment and said network element detect the presence of said silence descriptor packet, and said network element determines the optimized number of resource unit(s) to be allocated to said user equipment during the interval for transmitting said data packet, based on the coding rate of said user equipment, the selected modulation coding scheme and the valid transmission times; the network element starts timing and the user equipment stops using the allocated resource if a silence descriptor packet is detected; when the timing finishes or a request for allocating resource is received from the user equipment before the end of said timing, said network element allocates the determined optimized number of resource unit(s) to said user equipment, and said user equipment begins to use said determined optimized number of resource unit(s); said network element determines the end of the interval for transmitting said data packet by detecting the silence descriptor packet; and when both said user equipment and said network element detect a silence descriptor packet, said user equipment stops using said determined optimized number of resource unit(s), while said network element releases said determined optimized number of resource unit(s).
Abstract:
A method and system for processing messages within the framework of an integrated message system. Recipients of messages in an integrated messaging system are provided with an authentic impression of the received message. In a first step, a message received within the framework of an integrated messaging system is automatically translated. Language detection and dictation system is provided. The message contents of the incoming message as well as its segments and parameters are simultaneously utilized to generate additional information regarding the sender and the information, which is suitable to give the recipient an impression of the received message in the most authentic form possible.
Abstract:
This invention relates to virally-immortalized hepatocyte cell lines, which are derived from a normal primary human liver cell, have the ability to proliferate in a serum-free media, are nontumorigenic, and produce proteins. These cell lines can be used for toxicity testing of potential therapeutic drugs and chemical entities. The cell lines may also be used for the production of therapeutic plasma proteins.
Abstract:
Assessing open circuit and short circuit defect levels in circuits implemented in state of the art ICs is difficult when using conventional test circuits, which are designed to assess continuity and isolation performance of simple structures based on individual design rules. Including circuit blocks from ICs in test circuits provides a more accurate assessment of defect levels expected in ICs using the circuit blocks. Open circuit defect levels may be assessed using continuity chains formed by serially linking continuity paths in the circuit blocks. Short circuit defect levels may be assessed by using parallel isolation test structures formed by linking isolated conductive elements in parallel to buses. Forming isolation connections on a high metal level enables location of shorted elements using voltage contrast on partially deprocessed or partially fabricated test circuits.
