  • Publication number: 20100021477
    Abstract: Described and claimed herein are combinatorial synthetic Fab libraries displayed on a phage pIX protein. The libraries were built on scaffolds representing the most frequently used genes in human antibodies, which were diversified to mirror the variability of natural antibodies. After selection using a diverse panel of proteins, numerous specific and high-affinity Fabs were isolated. By a process called in-line maturation the affinity of some antibodies was improved up to one hundred-fold yielding low pM binders suitable for in vivo use. This work thus demonstrates the feasibility of displaying complex Fab libraries as pIX-fusion proteins for antibody discovery and lays the foundations for studies on the structure-function relationship of antibodies.

  • Patent number: 7362594
    Abstract: A resonant switching power system operates with two resonant frequencies. A first frequency depends on the secondary leakage inductance of an output transformer and capacitor. The first frequency varies with changes in the load because load changes alter the leakage inductance. A second resonant frequency depends on the gate source capacitance of two MOSFET power devices in the circuit and the leakage inductance of the circuit's driving transformer. Power is thereby supplied that is always in phase with the load so that switching in the power supply occurs when current is near zero. High thermal efficiency is thereby achieved.

  • Patent number: 7007882
    Abstract: A retractable badge reel with a billboard designed to display a logo, such that unadorned badge reels can be manufactured separately from the billboards that contain the logos. The billboard is optionally removable, allowing the logo being displayed to be changed without having to produce new retractable badge reels in their entirety. In another embodiment, a billboard designed to display a logo is adapted to be installed over the face of an existing retractable badge reel, such that the logo on the existing unit is hidden and the new logo on the billboard is instead displayed. A casement comprising the billboard and a back housing member have a mating portion that mates with a bob mating portion of a bob attached to the exterior end of the retractable cord to prevent the bob from shifting or twisting when the cord is in the retracted position.

  • Publication number: 20030095000
    Abstract: An apparatus and electrical circuit utilizing a high power Class “D” type amplifier for delivering an audio signal to a acoustic transducer system. A PWM modulator, the output of which is inhibited during power fluctuations or in absence of an audio input, converts a suitably conditioned audio input signal into low power, high frequency positive and negative components 180 degrees out of phase. A PWM signal power amplifier stage and low pass filters amplify the signal components, remove the higher PWM switching carrier frequency and pass the results to a power audio transformer impedance matched to the output acoustic transducers. Feedback signals are taken from the power stage before the low pass filters, suitably conditioned and combined as negative feedback with the input analog audio signal to minimize output distortion and maintain correct audio output voltage with changing load impedance and power supply voltages.
