摘要:
An integrated potentiostat includes a voltage controller that maintains within a predetermined range a potential between a reference electrode and a working electrode in an electrochemical cell. The integrated potentiostat further includes a capacitor that supplies or receives a current through the working electrode or reference electrode of the electrochemical cell. The rate of change of a voltage across the capacitor is functionally related to the current and thus provides a time equivalent of the current.

A system and method to facilitate transmitting a data message between a base station (108) and a mobile station (122) determines whether the base station (108) is compliant in operation with the mobile station (122). Based upon the determining whether the base station (108) is compliant with the mobile station (122), a service scheme is selected to process a data message (200) sent from the base station (108) to the mobile station (122), and the data message (200) is processed using the service scheme.
摘要:
A communication system, upon receiving an instruction to transfer deferrable data, determines whether an air interface is congested and, when the air interface is congested, defers a transfer of the deferrable data or transfers the deferrable, lower priority data as higher priority data. When, during a transfer of deferrable data, the system determines that the air interface is congested, the system may terminate the call and save a state of a partially completed deferred data transfer. Subsequent to the termination of the call, the system establishes another data connection over the air interface and transfers any remaining, not yet transferred deferrable data. In order to discourage subscribers from transferring higher priority data as lower priority data, the system may further restrict a transfer of lower priority data to designated time periods while allowing a transfer of higher priority data during the designated time periods and other time periods.

Various embodiments are described herein to address the need for reducing call setup delays with respect to supplemental channels. Modifications to channel assignment messaging (104), such as an enhanced ECAM, and service connection messaging (108), such as an enhanced SCM, are described. These modifications enable the assignment of SCHs (110) earlier in the call setup sequence. In addition, embodiments for determining and anticipating when such modified messaging may effectively speed the transfer of data (including VOIP) between a BS (201) and an MS (210) are described.
摘要:
A fractionating column is provided which has perforated fractionating trays and downcomers allowing liquid to flow from one tray to the tray immediately below, said downcomers being provided with radial outflow ports directing downflowing liquids towards the column wall rather than onto the surface of the tray directly below the downcomer. This permits at least a portion of the under-downcomer area to be perforated thereby increasing the capacity of the tray for vapor/liquid contact and ensuring that weeping of the liquid through the perforations is avoided without need for an increase in vapor pressure.
摘要:
Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. Signals from a subject are processed and analyzed and an estimate of a propensity for a subject to have a neurological event is determined. Based on the results of the analysis and the estimate, further analysis may be performed and the estimate may be refined. Succeeding cycles of signal measurement and analysis are scheduled depending on the results of the analysis and the estimate. The schedule may be varied temporally or with regard to the types and intensities of analyzes performed.

摘要:
A network access node (eNodeB for example) changing status from active to deactivated sends a message to a location server indicating the changed status. The location server collects from uplink messages indications of which of a plurality of cells have a deactivated status and stores this information in its local memory. Then the location server utilizes the stored indications to ensure that all cells in a list provided to a user equipment for location assistance will have an active status. In various embodiments: the message is sent only when the status is changed for energy saving purposes; a list of cells included in a location request message may have some deactivated cells so the location server sends a message to the eNodeB to activate deactivated cells in the list which is done prior to providing the list to a user equipment; and a partial-activation for a probing/beacon mode is disclosed.
摘要:
The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for controlling loading (e.g., pre-filling) of video data to a user equipment by a wireless network (e.g., from internet) while the video is played by the user equipment using an additional pre-filling based on predicted degradation of connectivity of the user equipment with the wireless network to avoid interruption or deterioration of playing the video and/or to reduce video data loading cost.
摘要:
An estimated spread value is computed that represents a price at which a trader might have been able to buy or sell a spread given the current market conditions of the legs. In particular, when an event occurs in one of the legs, price information is gathered from each of the other legs based on the spread definition, in addition to the defined event, and is used in estimating the value of a spread. According to one feature, the computations may be triggered by any predefined event. According to another feature, the computation may be programmed by a user to tailor the estimation process according to the type of spread being traded. The estimated spread value may be used to analyze spreads, it may be fed to other trading related software tools, or it may be used in charting.
