    Abstract: A system for detecting liquid in an inground lift has a tube with an open end disposed within the internal cavity defined by the containment housing of the inground lift. The tube is in fluid communication with a source of pressurized gas. A pressure sensor generates a signal if the pressure within the air line exceeds a predetermined level, which occurs if the end is blocked by liquid. A control system is configured to respond to the signal.

    Abstract: Propagation delay compensation in a wireless network comprising a central access point and multiple subscriber terminals is achieved by defining a registration time slot in which new subscriber terminals must first transmit network registration signals to the access point. The subscriber terminals by default transmit at the start of the time slot, and the access point times the delay from the start of the slot to the receipt of the subscriber terminal registration request, and then transmits this information back to the subscriber terminal. In all subsequent transmissions the subscriber terminal uses this information to delay its transmissions to compensate for differences in signal propagation delay between each subscriber terminal.

    Abstract: A method and system for providing wireless backhaul channels for use in a cellular radio network is disclosed wherein any of the subscriber terminals can be used as a backhaul terminal thus dispensing with the need for a dedicated backhaul terminal. In the preferred embodiment, the backhaul channel is integrated with the data channels provided for network payload communications, with the backhaul data being allocated the highest data priority and a traffic scheduler allocating the backhaul data time slots for transmission accordingly. This has the advantage that the bandwidth required for backhaul can be dynamically assigned to cope with the network loading at any time.

    Abstract: A storage device (10, 100) configured to be mounted to or near a house or other building for storing delivered goods. The storage device is shiftable between an expanded position wherein the device occupies a relatively large amount of space when in use and a collapsed position wherein the storage device occupies a relatively small amount of space when not in use.

    Abstract: A method of setting up a connection between two parties over a radio ATM network is provided. A remote, off-board agent, called the proxy signalling agent, is used to provide signalling and call control functionality for one or more network element(s). In order to receive and transmit signalling messages on behalf of the network element, a bi-directional virtual channel is provisioned, one for each port, from the network element to the proxy signalling agent. For each network element under the control of the proxy signalling agent, the proxy signalling agent provides signalling stacks, one for each of the elements ports, along with call admission control, routing and VCI allocation functions. This avoids the need for the network element to perform these functions. The proxy signalling agent controls the network element's connection tables using a simple and low-level control protocol to effect changes in the connection state at that element, rather than using UNI. As the network element does not need to provide signalling stacks, it can be a low cost, low complexity device. By making these devices as simple as possible, the overall reliability of the network can be increased.
