Title: Bird feeder
Inventor: CHRISCO LARRY L
IPC: A01K39/012
Filed: 2001-04-23
Abstract: A wildlife feeder has a generally tubular, upright housing or base unit that is designed to remain permanently attached to its means of support, such as an upstanding post or an overhead hanger, while refillable feed cartridges are readily removed from the housing as need be for refilling or cleaning. In its preferred form, the housing has a pair of internal, upright retaining sockets at its opposite ends that receive a pair of cylindrical, transparent cartridges. The cartridges are open at the top and closed at the bottom, with dispensing ports in the sidewalls thereof.  A pair of tall window openings at opposite ends of the housing provide both unimpeded visual examination of the feed level of the cartridges from remote locations and means for removing the cartridges from and reinserting them into the housing. A simple lift and pivot action of the cartridge permits the user to release the cartridge from its holding socket and to withdraw it from the housing, while reinsertion is a simple reversal of the process.

Title: System and method for time of arrival positioning measurements based upon network characteristics
Inventor: ZADEH BAGHER
IPC: H04W64/00
Filed: 1999-11-16
Abstract: An improved system and method for determining a position of a mobile station in a mobile telecommunications network is disclosed. The system includes a database having geographical information pertaining to the service area of the telecommunications network, including whether service areas therein are characterized as urban areas, suburban areas or "badurban" areas in which radio communication is especially limited. The system further includes a mobile location center (MLC) which, among other things, calculates the number of access signal bursts which are required for transmission by the mobile station to be located. The access burst number is calculated based upon the geographical information pertaining to the service areas stored in the database and upon a requested position determination accuracy. By measuring the time of arrival delay of the burst signal transmission received by two or more base transceiver station, the MLC computes the position of the mobile station.

Abstract: The Super Fast Jet Valve is a device used to open and close fluid movement with additional operation abilities, making it completely different from all other valves. All other valves are made to open and close at speed to avoid the 'destructive' force caused by over-pressure known as water hammer effect. The SUPER FAST JET VALVE operates, intentionally, to produce the water hammer effect. It uses it to increase the potential compression energy into a column of water by fast closing, then opens fast to convert the increase potential compression energy into kinetic energy of a jet. Between the closing and opening, the potential energy is renewed by pressure waves. The SFJ valve operation is required to let water expand due to the pressure waves developed by the water hammer. If the valve does not open fast enough, the over-pressure either cracks the container or makes the pressure waves bounce up an down in the container producing turbulences in lieu of increase kinetic energy of a jet.
