Title: Detecting and minimizing the effects of transmitter noise on signal strength measurement in a wireless communication system
Inventor: WARD TORBJORN
IPC: H04B17/00
Filed: 2000-01-18
Abstract: A system and method for minimizing effects of both internal and external transmitter noise in order to improve control decisions that are based on signal strength measurements. A wireless network includes an internal transmitter transmitting a first signal at a first frequency and noise at other frequencies in a known pattern. The signal strength of the first signa l is measured by the receiver at the first frequency. The noise of the transmitter of the first signal is calculated on other frequencies, using th e first transmitter's known noise pattern. A determination is then made whethe r the noise of the first signal is above a threshold on one or more of the oth er frequencies used by the wireless communication system. If the noise is above  the threshold, corrective action is taken. The wireless network further includes one or more receivers that measure signal strengths on the range of  frequencies used by the system. A correlation is made between the known spectral pattern of transmitters external to the system and the signal strength measurements. If the correlation is above a threshold, then externa l noise is present and corrective action is taken.

Inventor: LEFCORT MALCOLM D
IPC: F23J1/02
Filed: 2002-03-08
Abstract: In a two-stage waste burner, a first-stage combustion chamber has a symmetrical grate arrangement. The grate comprises spaced individual upright air supply tubes with flat horizontal upper surfaces swept by ash-removal plates. The height and width of the air supply tubes are selected to provide an upper surface profile approximating the natural angle of repose of the waste. Twin waste feed distribution augers span the chamber and rotate in mating troughs. The axis of rotation of each auger is sloped so that the discharge end of the auger is higher than the feed inlet end, and the trough sidewalls are inclined downwardly from the inlet end to the discharge end;  these attributes promote even discharge of waste across the span of the chamber.  Vertical walls of the air supply tubes are provided with air ports for supplying combustion air; the vertical orientation of the apertures and a degree of shielding of the upper surfaces of the air supply tubes inhibit clogging of the air ports. Drivers for the ash-removal plates comprise pendular arms each pivoting about an upper pivot point lying substantially in the vertical plane of symmetry, each arm being pivotally connected directly or indirectly to the ash removers.

Title: Electric vacuum cleaner
Inventor: YOSHIOKA TOMOKAZU
IPC: H02J7/00
Filed: 2002-03-20
Abstract: An electric vacuum cleaner according to the present invention boosts a voltage supplied to a motor-driven blower through the use of a boost converter circuit with a DC power supply as a drive source to thereby increase the output of the motor-driven blower so as to enhance dust suction power. The present invention provides, as operation modes of such an electric vacuum cleaner, an operation mode for boosting power inputted to the motor-driven blower with the boost converter circuit to thereby increase dust suction power, and an operation mode for deactivating the boost converter circuit. Consequently, the boost converter circuit is used to enable the boosting of the power inputted to the motor-driven blower only when really required, and a loss in power produced due to the mounting of the boost converter circuit can be reduced. Thus, the service hour per charge for a battery can be set to a level equivalent to an electric vacuum cleaner equipped with no boost converter circuit.

Title: Welded airbag cushion comprising sewn reinforcement seams
Inventor: KESHAVARAJ RAMESH
IPC: B29C65/04
Filed: 2000-09-12
Abstract: The present invention relates to a method utilizing welds, reinforced with sewn seams, to adhere two fabrics together to form an inflatable airbag cushion. Although welded seams provide better and more easily produced attachment points between multiple layers of fabrics, not to mention improve d manners of reducing air or gas permeability as such attachment points, the utilization of sewn seams adjacent to such welded areas provides stronger reinforcement, and thus more reliable nonpermeable fabrics. Seam welding generally concerns the utilisation of a film on the underside of a fabric which, upon contact with a second, film-treated fabric and upon exposure to high frequency energy, forms a bead of polymeric material at the attachment point between the two fabric layers. Lower numbers of sewn seams may be utilized to permit sufficient reinforcement if the size of the formed polymeric bead if of sufficient size to permit thorough sealing and adhesion  between the fabric layers. Such a specific reinforced fabric, as well as hig h bead-size welded airbag fabrics are encompassed within this invention.</SDOA B>
