Video coding
Pictures are coded using a coding algorithm with a variable parameter QP so that the quality of the coding varies. First (100), a target value TiMOS is specified for a quality measurement parameter.

Securing private key access for cross-component message processing
Often, for reasons of wireless bandwidth conservation, incomplete messages are provided to wireless messaging devices.

Alternatively, a server can assemble a composite message from a new message and an original message and, in cooperation with a wireless messaging device, sign the composite message. Since signing the composite message involves access to a private key, access to that private key is secured such that such access to the private key can only be arranged responsive to an explicit request for a hash that is to be signed using the private key. |

Multiwall carbon nanotube opto-electronic devices
A high-sensitivity detector for opto-electronic detection using multiwall carbon nanotubes (MWCNTs) is provided. More specifically, multiwall carbon nanotube films demonstrate an infrared bolometric photoresponse higher than SWCNT films at room temperature. The observed D* exceeding 3.3×106 cm Hz1/2/W with MWCNT-film bolometers and can be further improved to over 1×107 cm Hz1/2/W by adding graphene flakes. The response time of about 1-2 milliseconds with MWCNT bolometers is more than an order of magnitude shorter than that of SWCNT bolometers. For individual MWCNTs with specially designed asymmetric Schottky contacts, one on the sidewall and the other covering the end, the photocurrent has been efficiently harvested and provides a higher detectivity of 6.2×109 cm·Hz1/2/W at room temperature, which is one order of magnitude higher than the convectional VOx detector and makes MWCNT competitive for practical optoelectronic detections over infrared and even longer wavelength range. |
