Patent CA-2172565-A1 (CA)
Inventor: FOLADARE MARK JEFFREY
IPC: G06Q10/08
Filed: 1996-03-25
Abstract: It is possible to redirect a package in mid-transit, so as to deliver it to the addressee who will not be at the location to which the package was originally addressed when the package would otherwise be delivered. To do so, a package carrier, prior to delivering a package to an address specified by the sender, determines if the addressee desires the package to be rerouted to a different address. This determination is prompted by detection of the fact that the addressee is not in the vicinity of the address specified by the sender. The location of the addressee is determined from the location of a two-way pager associated with theaddressee as detected by a paging antenna, e.g., tower, of a conventional two-way paging. A comparison is made between the location of the addressee and the address specified by the sender. If there is a disparity and the addressee subscribes to the package special delivery redirection service, the package is then processed according to the instructions of the addressee. One instruction that can be left by the addressee is to call the addressee and ask if he wishes the package to be redirected, and, if so, what should be the new address. Another instruction that can be left by the addressee is to automatically reroute the package to a destination which may be determined as a function of the location of the addressee.

Abstract: A coextruded, multilayer polymeric film having a core layer including a surfactant and at least one outer layer is placed on a forming structure. The forming structure moves in a direction parallel to the direction of travel of the multilayer film and carries the multilayer film in that direction. A fluid pressure differential is applied across the thickness of the multilayer film along the direction of movement of the forming structure. The fluid pressure differential is sufficiently great to cause the multilayer film to conform with the forming structure forming a formed polymeric web. The formed polymeric web is exposed to a temperature which is sufficiently great enough to allow the surfactant in the core layer to migrate to the outer layer to form a surfactant treated formed polymeric web.

Inventor: VAN KERCKHOVE JEAN-FRANCOIS
IPC: H04L25/03
Filed: 1996-10-10
Abstract: A set of parameters (W) is calculated for an equalizer which equalizes a transmission line impulse response (LIR) in such a way that the equalized impulse response (EIR) approximates a target impulse response (TIR) with predetermined length (L). An error function (E) is minimized via eigenvalue-eigenvector calculation of a channel dependent matrix (O). This channel dependent matrix (O) is build up from a signal (X), a distorted signal (Y), and length (L) and delay (D) of the target impulse response (TIR). The error function (E) comprises a first contribution which represents the difference between the equalized impulse response (EIR) and the target impulse response (TIR) and a second contribution which represents the energy (EDC) that is transmitted in unused frequency bands. The eigenvector corresponding to the minimum eigenvalue of the channel dependent matrix (O) represents the set of equalizer parameters (W).
