Title: Bipartite graphical connection scheduling in time and space switch fabrics
Inventor: HUGHES ANDREW MILTON
IPC: H04L12/56
Filed: 2001-01-26
Abstract: A method of adding a new connection (c, d) to a time:space:time switch fabric. The fabric has a set I of k input ele-ments, a set M of m switch elements, and a set O of l output elements.      Each input element contributes one input to each switch element, and each output element receives one output from each switch element. A state S m characterizes the switch elements as a set of ordered pairs (i,j), where (i,j)~ S m if and only if the j th output element is coupled to the i th input element through one of the switch elements. The range of S m is the set of outputs of S m such that if j ~ range(S m) then (i,j) ~ S m for some i ~ I. The domain of S m is the set of inputs of S m such that if i ~ domain(S m) then (i,j) ~ S m for some j ~ O. If a switch state S m exists where c ~ domain(S m) and d ~ range(S m), then the new connection is added to S m as (c,d). If no such state exists, and if no switch state S m exists wherein c ~ domain(S m), then the method terminates because c is fully allocated. If there is a switch state S m wherein c ~ domain(S m), and if no switch state S n exists wherein d ~ range(S n), then the method terminates because d is fully allocated. If such a state S n exists, the two states S m, S n are joined to form a union J with each element (i',j') in J labelled u if (i',j') ~ S m, and each element (i',j') in J labelled v if (i', j') ~ S n. The new connection is then added to J as (c, d). A label (u or v) is allocated to the new connection. If new connection's label has not previously been allocated to a connection (i', d) ~ J the method termi-nates. Otherwise, the opposite label (v or u) is reallocated to connection (i', d) ~ J. If such opposite label has not previously been allocated to a connection (i',j') ~ J the method terminates. Otherwise, the originally selected label (u or v) is reallocated to connection (i',j') ~ J and the process repeats until no label conflicts remain. The originally selected label (u or v) is chosen to minimize the number of connections requiring reallocation of labels.

Title: Battery pack protection circuit
Inventor: PETERZELL PAUL E
IPC: H02H11/00
Filed: 1999-05-21
Abstract: A battery protection circuit (10) for an external battery pack (14) has a switch (40) for controlling connection of a battery output to a load, and a detector (44) for detecting a resistance at a load output terminal. A first comparator (50) compares the detected resistance (Rp) to a predetermined maximum value, and a second comparator (54) compares the detected resistance (Rp) to a predetermined minimum value. If the detected resistance is in the range between the minimum and maximum values, a control signal (42) is produced to enable connection of the battery output to the load. If the detected resistance is outside the range, the switch (40) is disabled and no current can flow to the load.

Patent CA-2350326-A1 (CA)
Inventor: ROBISON DAVID L
IPC: F16L41/06
Filed: 2001-06-11
Abstract: A method of replacing a gas main that supplies gas to a recipient through an existing service line includes connecting a first tapping tee to the new gas main and connecting a second tapping tee to the existing service line that communicates with a downstream recipient. Branch passages of the first and second tapping tees are fluidically connected together by a connecting conduit. The new gas main is then tapped with the first tee so that gas flows from the new gas main into the connecting conduit up to the second tee.      All air is bled from the connecting conduit between the first and second tees, and the existing service line is then tapped with the second tee so that gas is supplied to the recipient through both the existing service line and the connecting conduit. Gas flow to the recipient from the old main is then terminated. The second tee is a specially configured tapping tee specifically adapted for bleeding air from the connecting conduit that interconnects the first and second tees. This tee also utilizes a non-cylindrical bore for holding the conduit to be tapped to inhibit collapsing of the conduit during tapping operations.
