Title: Cyclone-type dust collecting apparatus for vacuum cleaner
Inventor: OH JANG-KEUN
IPC: A47L9/16
Filed: 2003-11-03
Granted: 2007-03-13
Abstract: Disclosed is a cyclone-type dust collecting apparatus for a vacuum cleaner. The apparatus comprises a cyclone body having an air inlet port and an air outlet port, for forming a vortex current of air which is introduced through the air inlet port and contains dust; a dust collecting container removably coupled to the cyclone body so as to collect the dust separated by centrifugal force of the vortex current in the cyclone body; a grill disposed at an upstream portion of the air outlet port in the cyclone body to prevent the air from flowing back through the air outlet port; and a fine dust filtering means disposed at a downstream portion of the grill in the cyclone body to collect fine dust which passes through the grill. And the cyclone body comprises a vortex current chamber formed with the air inlet port, a pressure drop chamber formed with the air outlet port, and also a path forming member for forming an air outlet guiding path by which the air containing the fine dust passing through the grill is flown from an upstream portion toward a downstream portion of the fine dust filtering means and then exhausted through the air outlet port, thereby preventing a backflow of the fine dust and increasing a dust collecting efficiency of the vacuum cleaner.

Abstract: An animal chew toy for carnivorous animals and a method for making the animal chew toy. The animal chew toy is primarily for dogs, and is safe, entertainment, and satisfies their inherent and instinctive need to chew. The chew toy is particularly safe for older dogs, dogs with weak jaws, and puppies with relatively new teeth. The chew toy is formed into a desired shape from a rawhide bit mixture of rawhide bits or pieces and a bonding agent and/or adherent. A plurality of flavor chunks, for example jerky pieces, are interspersed in the rawhide bit mixture to provide an enticing flavor and aroma that encourages an animal to continue to chew to reveal more flavor chunks. The rawhide bit mixture can further include health affecting additives. One method of forming the chew toy includes extrusion molding which can be coupled with baking or heat-treating to destroy unhealthy pathogens and solidify the chew toy. An elongated jerky member may be encased within the chew toy.

Abstract: This invention discloses methods for identifying Francisella tularensis vaccine candidates. It enables identification of novel vaccine candidates and quality assurance for vaccine batches, assessment of protection in vaccinates and identification of the infecting agent in vaccinates. Mice were first vaccinated with Brucella abortus O- polysaccharide (OPS) vaccine. These animals were then given 10 LD50s of F. tularensis live vaccine strain (LVS). Sixty percent (60%) of the vaccinated mice survived the multiple lethal doses. Sera were collected from these surviving mice and the antibodies were used to probe supernatant and cell lysates of live F. tularensis LVS cultures. Several F. tularensis components were identified only by the noted "survivor" antisera. Of these identified proteins, enzyme digestions and chemical oxidation suggest post- translational modifications of some proteins e.g. a 52 kDa glycoprotein, a 45 kDa lipoprotein and a 19 kDa nucleoprotein. The 52 kDa component caused nitrous oxide induction in tissue cultures at low concentrations, cell death at high concentrations. Vaccination with this gave partial protection while addition of other components acted synergistically to give enhanced protection from 250 LD50s of F. tularensis LVS.

Abstract: A mass filter is disclosed comprising an orthogonal acceleration electrode 9. Ions entering the mass filter are orthogonally accelerated by the orthogonal acceleration electrode 9 in a primary acceleration region 2 and enter a flight region 3. The ions 6, 7, 8 are then reflected by a reflectron 4 and are directed towards an exit region of the mass filter. Ions having a desired mass to charge ratio are arranged to arrive in the primary acceleration region 2 at a time when a voltage pulse applied to the orthogonal acceleration electrode 9 falls from a maximum to zero. Ions having a desired mass to charge ratio are orthogonally decelerated such that they have a zero component of velocity in the orthogonal direction. Accordingly, ions having a desired mass to charge ratio exit the mass filter in an axial direction.

Title: Signal, interference and noise power measurement
Inventor: CHEN ERNEST C
IPC: H04B7/185
Filed: 2003-08-26
Granted: 2010-11-23
Abstract: Systems and methods are presented for measuring power levels of primary and interfering signals as well as noise, particularly for satellite transmitted signals. A typical method comprises the steps of receiving a signal comprising a primary signal, an interference signal and noise, demodulating the primary signal to remove a carrier frequency, decoding the primary signal to obtain symbols, estimating a power level of the primary signal based upon the demodulated and decoded primary signal. Additionally, an ideal primary signal can be generated from the carrier power and frequency and the symbols and subtracted from the received signal to produce the noise and interference signal. The noise and interference power is then estimated from the noise and interference signal.
