Title: Regenerative braking apparatus for electric car
Inventor: YAMANAKA TAKESHI
IPC: B60W10/18
Filed: 2001-11-28
Abstract: <P>PROBLEM TO BE SOLVED: To effectively utilize regenerative electric power at braking.  <P>SOLUTION: When a battery is judged to be unable to be charged, an AC motor is short-circuited instead of supplying the regenerative power of the AC motor to the battery at braking. Thus, independent of the battery state, the motor is allowed to generate regenerative braking power, to assure stable braking. Since no conventional heating body (resistor) which limits installation place is required to be installed on an automobile, while the regenerative electric power is converted into braking power by a motor itself instead of consuming heat in a resistor, the regenerative electric power at braking is effectively utilized.  <P>COPYRIGHT: (C)2003,JPO

IPC: H04N1/387
Filed: 2001-11-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide an e-mail system capable of allowing a sender to anonymously send a secret letter by means of e-mail without being browsed by a third person on a communication pathway.  <P>SOLUTION: A receiver creates the envelope medium data in which an embedding/extracting key is concealed. This envelope medium data includes the personal information of the receiver. The image data or the acoustic data is used as the envelope medium data. The sender acquires the envelope medium data through the Internet. The sender embeds the secret letter in the acquired envelope medium data by a bit-plane segmentation steganography technique by using the embedding/extracting key. After the secret letter is embedded, the embedding/extracting key is eliminated from the envelope medium data. The sender transmits the envelope medium data in a state of being attached to the e-mail on the basis of the personal information. The receiver extracts the secret letter from the received envelope medium data by using the embedding/extracting key. As a result, the secret letter can be anonymously sent without being browsed by the third person on the communication pathway.  <P>COPYRIGHT: (C)2003,JPO
