Title: An improved manganese dioxide for lithium batteries
Inventor: FOOKSA RADEK
IPC: C01G45/00
Filed: 1996-06-05
Abstract: Disclosed is a process for treating manganese dioxide containing ion-exchangeable cations by replacing the ion-exchangeable cations present in the manganese dioxide with lithium by a process comprising first replacing ion-exchangeable cations present in the manganese dioxide with hydrogen. This readily is accomplished by slurrying the manganese dioxide in an aqueous acid solution. The resulting acidic manganese dioxide then is neutralized with a basic solution of a lithium containing compound, such as lithium hydroxide.  This neutralization step serves to accomplish replacement of the previously introduced hydrogen, by ion-exchange, with lithium. The manganese dioxide then is washed with water, dried, and heat-treated at an elevated temperature, in conventional manner, to convert the gamma manganese dioxide to a mixture of the gamma and beta forms, which then is used as the active cathodic component in an electrochemical cell.

Abstract: A data network to telephone network gateway (16) and an end-user computing device and method used by these devices are disclosed (26). The gateway (16) is in communication with both a data network (10) and a telephone network (12). The computing device (26) is in communication with the data network (10). The gateway (16) is adapted to receive an indicator of a telephone call and dispatch a notification of the call destined for the computing device (26). As well, the gateway (16) causes the call to be bridged from the telephone network to the computing device over the data network (10), enabling a user at the computing device (26) to communicate with the call using the computing device (26). After the call is bridged, and in response to a specified condition, the gateway (16) causes the call to be forwarded to a telephone line (34) interconnected with the telephone network. The specified condition may include an end-user input, or a detection by the gateway or the computing device that the quality of the bridged call has fallen below an acceptable standard, arising typically from congestion or delays on the data network (10). This allows the end-user to maintain a high quality call connection.

Title: Method and apparatus for polarisation-insensitive quantum cryptography
Inventor: TOWNSEND PAUL DAVID
IPC: H04B10/70
Filed: 1997-05-19
Abstract: A communication system uses quantum cryptography for the secure distribution of a key. A single-photon signal is phase-modulated and transmitted over a pair of time-multiplexed transmission paths. With each original single-photon signal in a given one of the transmission paths, a duplicate signal is transmitted. The duplicate is identically modulated and orthogonally polarised. At the receiver, the outputs of the two paths are combined interferometrically. A single polarisation-insensitive measurement is derived from the combined contributions of the orthogonally polarised signals.

Patent CA-2256804-A1 (CA)
Inventor: AIZAWA MASATOSHI
IPC: H04W88/02
Filed: 1998-12-21
Abstract: A portable radio information terminal provided with at least two means, namely, an input-signal judging means and a message-notification-operation halting means,  The input-signal judging means operates to form a judgment as to whether or not an input signal generated by an input device in the course of a message-notification operation is a rotary input signal generated by a rotary/press input device and supplies a result of the judgment to the message-notification-operation halting means.  The message-notification-operation halting means continues the message-notification operation as it is if the result of the judgment received from the input-signal judging means indicates that the input signal is a rotary input signal, otherwise halts a message notifying unit currently carrying out the message-notification operation.      Thus, the effect of an inadvertent input signal generated by an external force accidentally applied to the potable radio information terminal can be eliminated.          As a result, it is possible to implement a highly reliable portable radio information terminal and a message-notification method for the portable radio information terminal.
