Inventor: STEIN MYRON
IPC: B60H3/00
Filed: 2002-04-18
Abstract: An apparatus and method for drying condensate from the heat exchange of a vehicle's air conditioning system after operation in order to thwart odor buildup. The apparatus and method operate regardless of whether the system's blower control circuit (17) is positively or negatively switched.

Patent CA-2446395-A1 (CA)
Inventor: MARKO PAUL
IPC: H04L1/08
Filed: 2002-05-07
Abstract: A method and apparatus for convolutionally encoding (30) and interleaving (46, 48) a source data stream for transmission on one or more transmission channels (66, 68). Convolutionally encoded data groups (36) are time-interleaved (46) to disperse selected bits of puncture groups (45) in the data groups, bits in between data groups, and bits in selected sets of data groups, facilitating reconstruction of the source data from at least a portion of the interleaved data received on at least one transmission channel. The time-interleaving functions (46) are selected to facilitate reconstruction of the source data from one transmission channel following continuous blockage. Puncture groups are selected to allow reconstruction of the source data using a minimum number of puncture group bits. Multiple combinations (44a-44d) of puncture group bits can be used to reconstruct the source data following blockage of one channel.  A Viterbi decoder (26) performs decoding.

Title: Isn call interrupt
Inventor: VOGNSEN DAVID K
IPC: H04M15/00
Filed: 2002-06-05
Abstract: A device and method of intercepting in-progress calls whose billing numbers have been marked fraudulent subsequent to the initial authorization and validation of the same in-progress calls. The device and method uses criteria to define certain calls as "suspect" and parks all suspect calls after the initial call processing. Because the suspect calls are parked and not released to the general switching elements of the telephone network, the suspect calls can be torn down if the associated billing number is marked fraudulent after call processing. The criteria can maintain a fine granularity by using various Call Park Flags in various databases. In addition, the suspect calls can remain parked for varying amounts of time based on the category and type of call.
