Title: Wireless data communications network and method for operating the data communications network
Inventor: PRIBIL KLAUS
IPC: H04B10/112
Filed: 2000-05-01
Abstract: The present invention relates to a data communications network and a method for operating the data communications network, wherein the data communications network essentially consists of fixed stations on or near the ground and freely movable flying objects, which are linked together by means of wireless data links. The concept of the invention is based on interruption-free optical laser communications between various flying objects, which typically operate above the cloud tops. These laser-optical data links offer the greatest degree of interception security, and in addition can be advantageously built up or changed very rapidly.   Since the individual flying objects operate independently of each other over a wide range, a maximal autonomy of the communications network can be assured. In particular is it possible by means of this to reconfigure the data communications network very rapidly and to adapt it in this way to changed conditions. Moreover, redundancy, and therefore greater flexibility in the topology of the data communications network, can be created by the use of additional flying objects.

Title: Fluorimetric detection system of a nucleic acid
Inventor: LEE MARTIN ALAN
IPC: C12Q1/6823
Filed: 1998-11-27
Abstract: A method for detecting the presence of a target nucleic acid sequence in a sample, said method comprising: (a) adding to a sample suspected of containing said target nucleic acid sequence, a probe specific for said target sequence and DNA duplex binding agent, said probe comprising a reactive molecule able to absorb fluorescence from or donate fluorescent energy to said DNA duplex binding agent, (b) subjecting the thus formed mixture to an amplification reaction in which target nucleic acid is amplified, (c) subjecting said sample to conditions under which the said probe hybridises to the target sequence, and (d) monitoring fluorescence from said sample. This method can be used for example to monitor amplification reactions such as PCR reactions, such that the amount of target sequence present in the sample may be determined. Additionally or alternatively, it may be used to generate duplex destabilisation data such as melt hysteris information for amplification monitoring or for detection and quantitation of polymorphisms or allelic variation, and so is useful in genetic diagnosis.

Title: Synchronous spread-spectrum communications system and method
Inventor: SCHILLING DONALD L
IPC: H04B1/69
Filed: 1991-12-10
Abstract: A spread spectrum communications system for use over a communication channel, including a transmitter-generic-chip-code generator (101), a transmitter-message-chip-code generator (102), an EXCLUSIVE-OR gate(103), a combiner (104), a transmitter (107), a receiver-generic-chip-code generator (121), a receiver-generic mixer (123), a generic-bandpass filter (125), a receiver-message-chip-code generator (122), a receiver-message mixer (124), a message-bandpass filter (126), and a synchronous detector (139). The transmitter-generic-chip-code generator (101) generates a generic-chip-code signal and the transmitter-message-chip-code generator (102) generates a message-chip-code signal. The EXCLUSIVE-OR gate (103) spread-spectrum process message data with the message-chip-code signal to generate a spread-spectrum signal. The transmitter (107) transmits the combined generic-chip-code signal and spread-spectrum signal, on a carrier signal (108) over the communications channel as a spread-spectrum-communications signal. The receiver-generic-chip-code generator (121) generates a replica of the generic-chip-code signal. The generic mixer (123) recovers the carrier signal from the spread-spectrum-communications signal. The receiver-message-chip-code generator (122) generates a replica of the message-chip-code signal. The receiver-message mixer (124) despreads the spread-spectrum-communications signal as a modulated-data signal. The tracking and acquisition circuit (121) uses the recovered carrier signal for synchronizing the replicas of the generic-chip-code signal to the recovered carrier signal. The synchronous detector (139) synchronously demodulates the modulated-data signal as received data.

Title: Methods for enhancing antigen-presenting cells and anti-tumor responses in a human patient
Inventor: KIERTSCHER SYLVIA MARIE
IPC: A61K38/00
Filed: 1999-04-02
Abstract: The present invention provides methods for enhancing the development of APC from precursor cells by administering a combination of GM-CSF and IL-4. The precursor cells include: cells contained in peripheral blood, CD14+ cells and precursors in bone marrow. Thus, administration of GM-CSF and IL-4 can be used as a form of cytokine immunotherapy. One embodiment of the present invention involves systemic administration of GM-CSF and IL-4. In this embodiment, APC are required to directly access tumor antigens as they exist in vivo within the patient. A further embodiment of the present invention involves coadministration of a tumor-associated or tumor-specific antigen, with GM-CSF and IL-4, to induce antigen-specific immunity mediated by APC. Yet another embodiment of the present invention describes systemic administration of GMCSF and IL-4 to achieve reduced tumor burden.

Title: Suspension system for inline skates
Inventor: MOSES JAMES D
IPC: A63C17/06
Filed: 2001-01-05
Abstract: A suspension system for use with inline skates. The suspension system employs a mounting bracket that supports a flex beam on a left side and a flex beam on a right side of the mounting bracket. Downwardly extending tabs formed at the ends of the flex beams are each connected to an axle on which one of a plurality of wheels is supported. In a preferred embodiment, four inline wheels are connected to the flex beams, such that the first and third wheels are attached to one flex beam and the second and fourth wheels are attached to the other flex beam. This configuration allows the end of each flex beam and the wheel mounted thereon to deflect vertically as well as laterally and about a longitudinal axis of the flex beam. An independent suspension system is thus provided for each wheel. The ends of the flex beams are tapered (in thickness) to control the resiliency of the flex beams.
