  • Patent number: 5991620
    Abstract: A telecommunications system and method is disclosed which avoids unwanted feature interactions while positioning a mobile station that was in idle mode when the positioning request was received by the network. When the serving MSC/VLR receives a request to collect positioning measurements for a mobile station that is in idle mode, the serving MSC/VLR will set an indicator associated with the subscriber to "busy for connection management due to positioning". This flag will allow the MSC/VLR to make a distinction between a positioning connection and the normal mark of "busy for connection management". Thereafter, when a mobile terminating call arrives to the MSC/VLR for a subscriber that is marked as "busy for connection management due to positioning", the MSC/VLR can place the incoming call in a queue until the positioning measurements are taken and the subscriber being positioned is put back in idle mode.

  • Patent number: 5754009
    Abstract: An interfacing system adapted for use with integrated circuits and accompanying devices. The inventive system includes an array of field emissive devices (36) which emit an electrons in response to input signals from multiple first circuits (14) on a first substrate (16). The field emissive devices (36) are located on the first substrate (16). An array of detectors (38) on a second substrate (20) receive the electrons across a (gap (42) between the first substrate (16) and the second substrate (20). A potential difference in response to a source of potential (22) between the first substrate (16) and the second substrate (20) accelerates the electrons across the vacuum gap (42). The interfacing system (10) may be constructed with a diameter of less than ten micrometers. Hence, two substrates with multiple circuits may be interfaced with many thousands of parallel connections per square centimeter without the need for multiplexing.

  • Patent number: 5205004
    Abstract: A vertically adjustable and tiltable bed frame has two actuators which may be used simultaneously or independently to tilt the frame and which also may be used to raise and lower the frame. A level sensor is connected to the actuators so that if the tilt varies from the adjusted and desired position, one or other actuator is adjusted to restore the desired tilted position.

  • Patent number: 5161274
    Abstract: An adjustable bed comprises a frame having a backrest arranged to be lifted by an actuator via a crank, and a thighrest similarly arranged to be lifted by an actuator. A legrest is freely pivoted to the thighrest. The angles of the parts are sensed and maintained in proportion by control means, so that as, for example, the backrest angle is steepened, the thighrest is also raised proportionately, but to less extent, taking the legrest with it.

  • Patent number: 4015631
    Abstract: The invention provides a gas tap particuarly intended to be made of aluminium, using an axially movable plunger to control flow, in which the tip of the plunger is modified for low rate flow control, by providing a low rate flow passage in the tip of the plunger.
