It has now been found that in some transmitter implementations which transmit multiple code channels, for example CDMA transmitters, the observed power for each code channel at the output relative to the other code channels is dependent upon the total transmit power due to non-linearities in the transmitter. Methods and apparatus are provided which use pre-set digital gains or digital gain adjustments to compensate for the non-linearities as a function of total transmit power such that at the output, the desired relative powers are observed.
摘要:
A valve drive assembly cooperable with gas exchange valves of an internal combustion engine having a cam shaft and at least one came support rotatably fixed and axially displaceable on the cam shaft and having at least two cam profiles selectively engageable with a roller provided on a follower engageable with a valve comprising a cam support having a cylindrical surface disposed coaxially with a cam shaft, provided with a pair of oppositely inclined, spiral grooves; and means selectively insertable into the grooves, coacting with side walls of such grooves as the cam shaft rotates to effect axial displacement of the cam support.
摘要:
The disclosure relates to a steam stripping process for producing purified polyimides, e.g., polyetherimide homopolymers and polyetherimide copolymers. The process can include contacting an initial polyimide with steam to remove a volatile species from the initial polyimide to produce a purified polyimide. The purified polyimide can have a weight average molecular weight of from 5,000 to 80,000 Daltons. The weight average molecular weight of the purified polyimide can be greater than or equal to 90% of the weight average molecular weight of the initial polyimide. The purified polyimide can have less than 44 ppm of a volatile species, having a molecular weight of less than 250 Daltons. The polyimide can have less than 10 ppm of a metal cation.
摘要:
The NSAID, sulindac and/or its metabolites and derivatives, in combination with an agent that generates or induces reactive oxygen species (ROS), significantly enhances the killing of abnormal cells but does not affect normal cells. This effect occurs at concentrations of each compound that individually have little or no activity directed against the abnormal cells.

摘要:
A lighting system distinguishes between light from natural and manmade sources to prevent the system's light source from being inadvertently deactivated due to light received from manmade light sources. A sensor converts received light into electrical energy. The system light source and/or some other external light source can emit light with a modulation. The system includes a modulation detector that can detect the modulation in the electrical energy received from the sensor. A system controller selectively adjusts the flow of electrical energy to the system light source responsive to the electrical signals from the sensor. The controller adjusts the flow of electrical energy in response to the non-modulated component of the electrical signals from the sensor. The controller does not adjust the flow of electrical energy in response to the modulated component of the electrical signals from the sensor.
摘要:
In a synchronous remote mirroring system, as a host computer writes data to primary storage in a primary data storage system, remote copy data is transferred from the primary data storage system to a secondary storage system in which secondary storage is maintained as a remote mirror of the primary storage. The primary data storage system performs data reduction upon the remote copy data prior to transmitting the remote copy data in a reduced to the secondary data storage system. The secondary data storage system returns an acknowledgement of receipt of the remote copy data upon receipt of the remote copy data in the reduced form, and later reverses the data reduction upon the remote copy data in the reduced form to produce data written to the secondary storage to maintain the secondary storage as the remote mirror of the primary storage.
摘要:
A handheld electronic device and an associated method are provided. The handheld electronic device includes a keyboard assembly, a display positioned adjacent the keyboard assembly, a processor structured to receive inputs from the keyboard assembly and to output to the display as a function of the inputs, the processor further structured to run a disambiguation routine. The keyboard assembly includes a printed circuit board, a primary conductor portion, a secondary conductor portion, and a keyboard assembly. The printed circuit board has a plurality of electrical contacts. The conductor assembly has a plurality of primary conductors and a plurality of secondary conductors, each the primary conductor and secondary conductor structured to correspond to, and engage and close, at least one of the plurality of electrical contacts. The keyboard assembly has a plurality of keys each having one or more indicia thereon.
摘要:
A search facility may optimize search result ranking by applying inverted decay transformations to history-dependent ranking components. Ranking scores for content in a content collection may be based on a set of ranking components including history-dependent ranking components. History-dependent ranking components may be based on historical behavioral data such as historical searches, actions taken with respect to content such as viewing content and content-related purchases. Content recently added to the content collection may be disadvantaged relative to content with an established history. Inverted decay transformations may correspond to simulations of additional historical behavioral data.
