1. A method for managing a secure element which is embedded into a host unit, the method comprising:
transmitting a request for a management script from the host unit to a program element of the secure element,
at the program element, generating a management script in accordance with the request and encrypting the generated management script,
transmitting the encrypted management script from the program element to the host unit,
transmitting the encrypted management script from the host unit to a secure domain of the secure element, and
at the secure domain, decrypting and executing the management script,
wherein the request comprises a parameter value which is to be used to generate the management script, and
wherein the host unit is a mobile communication unit and the parameter value is an International Mobile Equipment Identity of the mobile communication unit.
2. The method according to claim 1, wherein the program element and the secure domain comprise corresponding key sets for encrypting and decrypting.
3. The method according to claim 1, wherein the request comprises an identification of the management script.
4. (canceled)
5. (canceled)
6. The method according to claim 1, wherein the management script is configured for performing a secure element management operation selected from the group consisting of a secure element lock operation, a secure element unlock operation, a secure element reset operation, a key modification operation, a program element delete operation, and a program element modification operation.
7. (canceled)
8. (canceled)
9. A secure element for a host unit, the secure element comprising a management applet for locally managing the secure element which is embedded into the host unit, the management applet comprising instructions which when executed by a secure element processor causes the secure element processor to perform the steps of
receiving a request for a management script from the host unit, generating a management script in accordance with the received request, encrypting the generated management script, and transmitting the encrypted management script to the host unit; the secure element further comprising:
a processing unit adapted to execute the management applet, Where the secure element further comprises:
a secure domain adapted to receive the encrypted management script from the host unit and to decrypt and execute the management script,
wherein the received request comprises a parameter value used to generate the management script,
wherein the host unit is a mobile communication unit and the parameter value is an International Mobile Equipment Identity of the mobile communication unit.
10. A mobile communications device comprising an embedded secure element according to claim 9.
11. A computer program product comprising a computer readable data carrier which when executed by a computer causes the computer to perform the steps of the method according claim 1.
12. (canceled)
13. A secure element according to claim 9, wherein the step of encrypting uses a set of cryptographic keys corresponding to a set of cryptographic keys which is stored in a secure domain of the secure element.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A projection type image display apparatus for projecting imaging light formed by modulating a beam of source light based on an image signal, said image display apparatus equipped with an exhaust mechanism for exhausting air from the image display apparatus that includes a light source unit and discharging said air out of the image display apparatus, said exhaust mechanism having
a first exhaust fan for mainly exhausting air from said light source unit and discharging said air out of said image display apparatus; and
a second exhaust fan for mainly exhausting air from the components other than said light source unit and discharging said air out of said image display apparatus, said second exhaust fan having an inspiration face arranged to partly overlap the expiration face of said first exhaust fan.
2. The image display apparatus according to claim 1, wherein said second exhaust fan is adapted to mainly exhaust air from the power supply unit to the outside of the image display apparatus.
3. The image display apparatus according to claim 1 or claim 2, wherein said first and the second exhaust fans are preferably arranged at oblique angles with respect to an exhaust port therefor.
4. The image display apparatus according to claim 1 or claim 2, wherein said first and second exhaust fan are oriented in an oblique forward direction with respect to an exhaust port formed in a side wall of said image display apparatus.
5. The image display apparatus according to claim 1 or 2, wherein said second exhaust fan has less output power than said first exhaust fan.
