Abstract: A predistortion circuit for a microwave amplifier and more particularly to predistortion circuit configured as a Doherty amplifier. The predistortion circuit is adapted to be coupled to a downstream Doherty amplifier to precompensate for the gain compression and phase expansion of the downstream Doherty amplifier as the input power level is increased while simultaneously reducing the intermodulation (IM) distortion. In order to provide precompensation, the precompensation circuit is operated at bias level to provide gain expansion and phase compression to cancel out the gain compression and phase expansion of the downstream Doherty amplifier to provide a higher overall linear power added efficiency (PAE).

Title: Method for emergency service access using a mobile phone
Inventor: CARLEY JEFFREY A
IPC: H04W4/90
Filed: 2000-12-01
Abstract: There is provided a method for emergency service access using a mobile telephone. When an emergency situation arises and a caller enters an emergency number such as 911 [send] from a locked mobile telephone, the mobile telephone compares the entered value (911) with a list of emergency numbers stored in the memory of the mobile telephone. If the entered number is on the known emergency number list, the mobile telephone immediately places the emergency call even though the telephone is locked. All other key combinations will be compared to a user defined access code previously stored in memory. If the entered value matches the value stored in memory, the mobile phone will be unlocked and ready for normal use. If the values do not match, the mobile phone will remain disabled. In addition, during an emergency call, a mobile provider provides a set of emergency contact records (ECR) to an emergency public service answering point (PSAP). These emergency contact records may include information for each member in the family, including the individual's name, home address, phone number, physical description, emergency contact name and number, doctor's name and number, emergency medical information, such as drug allergies, temporary conditions, such as a pregnancy, a digital image, and any other information the subscriber deems relevant for the PSAP to know in an emergency. In the event the subscriber places a call while not in the subscriber's home system, the local MSC will send a request to the subscriber's home system, asking the home system to send the subscriber's ECRs to the PSAP. Inan additional embodiment of the invention, the MSCs will send a request to an independent organization which maintains ECRs and request the organization to send the information to the PSAP selected by the MSC.

Title: Power lever tactile cueing system
Inventor: SCHAEFFER JOSEPH M
IPC: B64C27/28
Filed: 2001-05-16
Abstract: The present invention is a power lever tactile cueing system (13) for providing tactile alerts to pilots as operational limits of an aircraft (11) are approached. The cueing system (13) generates a tactile cue (C) comprising a variable dive rate (51) and a variable friction force (53) on a power lever (33) of an aircraft. The cueing system (13) provides spring-like tactile cues (C) when power commands reach a predetermined operating limit, without the use of mechanical springs. The cueing system (13) trims down the power lever (33) position and provides the additional friction force (53) based upon aircraft (11) and engine state. The cueing system (13) remains activated until the aircraft (11) is again operated within its operational limits. The pilot may override the cueing system (13) in certain situations.

Title: Method for transmitting information using chaotic signals
Inventor: KYARGINSKII BORIS EGOROVICH
IPC: H04J13/00
Filed: 2000-07-27
Abstract: The invention relates to transmission of data with spectrum-spreading by mea ns of chaotic signals. The invention makes it possible to develop straight chaotic communication systems, in which data is introduced into a chaotic signal which is generated directly within a band for data transmission. The aim of the invention is achieved by formation of a broadband data carrier required for transmission with the aid of a chaotic dynamic system whose structure is pre-synthesised in accordance with predetermined characteristic s of said data carrier in such a way that the chaotic system can form a broadband data carrier in the form of a chaotic data carrier displaying the requisite spectral characteristics. Modulation of the chaotic data carrier occurs by forming a chaotic radio and optical impulses therefrom having a predetermined duration and predetermined time intervals therebetween with respect to a transmitted data signal. Reception and demodulation on the receiving end is carried out with the aid of the dynamic system co-ordinated  in relation to the behaviour thereof with the chaotic dynamic system of the transmission end.

Title: No wash bead assay, kit and procedure
Inventor: HECHINGER MARK K
IPC: C12Q1/6834
Filed: 2001-06-04
Abstract: A method of making a no wash bead based assay comprises preparing a first reagent comprising a buffer, and preparing a second reagent comprising a protein. Beads of preselected size and having a coefficient of variation less than 5 % are prepared, including washing the beads in the buffer to form a bead-buffer matrix and reducing the surfactancy of the beads to an effective amount. Thereafter, an antigen for detecting the presence of a target species is added to the bead-buffer matrix such that the antigen attaches to the beads to form a bead-antigen mixture. The surfactancy of the beads facilitates attachment of the antigen thereto. Buffer is added to the bead-antigen mixture and thereafter the mixture is incubated. The second reagent is added to the bead-antigen mixture to reduce or eliminate non-specific binding sites.
