Abstract:
Power switch units for microelectronic devices are disclosed. In one aspect, a microelectronic device may include a functional circuit, and a power switch unit to switch power to the functional circuit on and off. The power switch unit may include a large number of transistors coupled together. The transistors may include predominantly positive-channel, insulated gate field effect transistors, which have a gate dielectric that includes a high dielectric constant material. Power switch units having such transistors may tend to have low power consumption. In an aspect, an overdrive voltage may be applied to the gates of such transistors to further reduce power consumption. Methods of overdriving such transistors and systems including such power switch units are also disclosed.
Abstract:
A two stage fully differential amplifier has been designed which works, in tandem with a TX-FIR, as a linear equalizer at low frequencies, not covered by the TX-FIR, and also acts as a linear amplifier at higher frequencies which are equalized by the TX-FIR. The amplifier as a frequency response which does not attenuate signals frequencies less than one twentieth of baud rate, creates gain peaking ion the region between one twentieth and one tenth of baud rate and maintains flat peak gain up to half of baud rate. Different aspects of the frequency response curve (such as dc gain, max gain and zero frequency) are completely programmable. Also, the differential amplifier has been designed from low power and process, voltage and temperature insensitive frequency response.

Abstract:
A method and system for establishing a call between two endpoints residing on different media gateways in a decomposed voice over packet architecture. Cluster attributes identifying alternate bearer possibilities are exchanged between media gateways as part of capabilities negotiation which occurs during call setup conducted by an external call control element over a core network. The media gateways analyze the cluster attributes to determine whether bearer possibilities exist apart from the core network. If an alternate bearer possibility exists, the alternate is employed and the call is established via the alternate bearer directly between the media gateways, thus bypassing the core network.
Abstract:
Text is interleaved and transported along with media data over the same real-time Internet Protocol (IP) media transport session. A network processing device identifies text characters corresponding with text signaling. The identified text characters are formatted into text packets and sent over the same real-time IP media transport session used for real-time media transport. The media transport session can identify the sequence that the text characters are transmitted and can specify a maximum character transfer rate.
Abstract:
A polyol includes the reaction product of an epoxidized oil and an organic acid. The epoxidized oil and the organic acid are reacted in the presence of a Lewis base catalyst including at least one of a phosphorous atom or a nitrogen atom. The polyol is formed by a method that includes the step of reacting the epoxidized oil with the organic acid in the presence of the Lewis base catalyst.
Abstract:
Polymers having a main chain having both aromatic units and aliphatic units (with repeating heteroatoms) and a side chain macromonomer are described. Methods of making these polymers using enzymatic synthesis and the applications of these polymers are also described.
Abstract:
A method for converting packet-based voice data of a first format directly to packet-based voice data of a second format, and vice versa. Data from networks using non-compatible packet-based voice technologies, for example, VoATM and VoIP, are interworked for direct conversion. Connection is set between an edge gateway of a first voice packet network, having data in a first format, and an interworking unit (IWU). Another connection is set between this IWU and an edge gateway of a second voice packet network, having data in the second format. The IWU is controlled by a single call agent that co-ordinates the conversion, at the IWU, between the two packet formats. Because it has this capability, this call agent is also called the “conversion server”. This call agent may be identical to the call agent used to control one or both edge gateways that use different packet based technologies.
