Patent CA-2266774-A1 (CA)
Inventor: LIU JIEWEN
IPC: H02J7/10
Filed: 1997-09-19
Abstract: A unified battery charge method allows for controlling constant as well as time varying current sources. Unlike the charging method used for a constant current source, the input current of a time varying current source must be checked continuously during the charging process. The amount of current output to charge the battery or to supply the phone power is set to a desired value by selecting duty-percentage based upon the input current measurement. A  unified formula for different power sources and various required current improves the preferred output current computation. Thus, the unified formula can be used to control input and output currents regardless of whether a constant current source or a time varying current source is used. In order to obtain smoother current average, the method incorporates an adjustable time period, which is determined based on the difference between an input current and a desired output current.

Patent CA-2276872-A1 (CA)
Inventor: PATEL SARVAR
IPC: H04L9/32
Filed: 1999-07-02
Abstract: In the method for protecting mobile anonymity, the network sends a temporary mobile identifier (TID) update request to the mobile along with a challenge. In response, the mobile encrypts its permanent ID through public key encryption using the public key of the network, and sends the encryption result to the network. Also, the mobile generates a second challenge, and a first challenge response. The first challenge response is generated by performing a keyed cryptographic function (KCF) on the first and second challenges using a key. The mobile sends the second challenge and the first. challenge response to the network with the encrypted permanent ID. After decrypting the permanent ID, the network accesses the key associated with mobile using the permanent ID. Next, using the key, the network authenticates the mobile using the second challenge and the first challenge response. If authenticated, the network calculated a TID for the mobile using the first and second challenges. The network further generates and sends a second challenge response to the mobile. If the mobile authenticates the network based on the second challenge response, then the mobile calculates the TID in the same manner as did the network.
