  • Automatic vehicle identification system capable of vehicle lane discrimination
    Patent number: 5701127
    Abstract: A method of identifying an object and determining in which of at least two areas the object is located is disclosed. The method includes the steps of: focusing a first directional antenna (18) on a first area (28a), focusing a second directional antenna on a second area (28b), transmitting a first field strength pulse (44) from said first directional antenna (18), transmitting a second field strength pulse (46) from said second directional antenna (18), and comparing in a transponder (14) the first field strength pulse (44) to the second field strength pulse (46) to determine in which of the two areas (28a,28b) the transponder (14) is located. Other devices, systems and methods are also disclosed.

  • Breathing apparatus
    Patent number: 5651361
    Abstract: Breathing apparatus supplies air or oxygen to a patient and comprises a hand-held housing (10), a gas inlet on the housing, a gas outlet (12) on the housing (10), and a manual/automatic switch (16) on the housing for supplying gas either to a manually operable valve (40) or to a main valve (48) which delivers gas to the outlet on a cyclic basis. A trigger (22) on the housing (10) controls the supply of gas to the outlet through the manually operable valve (40).
