Patent CA-2438721-A1 (CA)
Title: Method for an automatic callback in a packet-oriented network
Inventor: HORVATH ERNST
IPC: H04M7/00
Filed: 2002-01-30
Abstract: In cases when a called participant (Tln-B) is not registered on a packet orientated network (IP-N), a call-back request made by a calling subscriber (Tln-A) is transmitted automatically to a substitutional device (ST-B) which is disposed in a network (IP-N) and assigned to the called subscriber (Tln-B). Preferably, the call-back request is stored in a separate data base (DB-B). As soon as the called subscriber (Tln-B) is registered in the network (IP-N), the call-back request is transmitted to the called subscriber (Tln-B) who carries out said request.

Title: Method and system for sustainable digital watermarking
Inventor: CHOW STANLEY T
IPC: G06F21/16
Filed: 2002-06-10
Abstract: Digital marks (so-called fingerprints and watermarks) serve two basic purposes: (1) Investigative: the owner reads a fingerprint to determine how the marked entity leaked; and (2) Legal: the owner must prove in court that (a) there is a watermark (a concealed copyright message), and (b) it is the owner's. The main difficulty of item (2) is that the first use of the watermark software reveals the watermarking method to the public so that hostile parties are equipped to remove or damage its watermarks. The inventi on uses tamper-resistant software encoding techniques to protect the digital ma rk extractor algorithm, frustrating the attacks of hostile parties in two ways: the resulting code is obscure (that is, its inner workings are incomprehensible; and chaotic (that is, a modification at any point will almost certainly produce a nonsense program.

Abstract: An arrangement (10) for controlling the liquid level in a basin (60) by selectively actuating a pump (64) has an environmentally-sealed enclosure (22) with an internal volume subject to thermal and pressure effects. A first (14) and a second (16) pressure sensing means are positioned in the enclosure and a barrier fluid (18) fills a balance of the internal volume. The first sensing means (14) is in a first chamber (22a) of the enclosure (22) and the second sensing means (16) is in a second chamber (22b). The barrier fluid (18) has a first portion (18a) in the first chamber (22a) and a second portion in the second chamber (22b). The first pressure sensing means (14) communicates an "on/off" signal to the pump (64). Diaphragms (26, 40) in the respective chambers (22a, 22b) allow the device to adjust to changes in atmospheric pressures. The barrier fluid (18) is electrically non-conductive, chemically non-reactive with any materials comprising the pressure sensing means and, preferably, an oil.
