International Classification:

H04N 5/455
H04N 5/50
H04N 7/12

US Classification:

348726, 348731, 37524001, 348E05113, 348E05097, 375E07076

Abstract:

A broadcasting signal receiver system containing a multi-standard-compatible dedicated processing unit and a general system resource is disclosed, wherein the multi-standard-compatible dedicated processing unit is configured to process one or more tuning processing steps and/or one or more demodulation processing steps, and wherein the general system resource is configured to process at least one collaborative demodulation processing step with the multi-standard-compatible dedicated processing unit via a high-speed data transfer interface. By utilizing the general system resource for at least one demodulation processing step using the high-speed data transfer interface such as USB 3.0 or PCI Express, the broadcasting signal receiver system can have a flexible design for future updates and a cost-effective compatibility to a multiple number of broadcasting standards without requiring the dedicated processing unit to use more application-specific hardware resources.

Appl. No.:

6/731715

Inventors:

Stephen Y. Chou - Stanford CA

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

G01P 1508

US Classification:

73517R

Abstract:

A highly sensitive accelerometer is disclosed in which the current is measured across a pair of electrodes resulting from voltage pulses from a pulse generator. The electrodes are located within a vacuum chamber. One of the electrodes is cantilevered and has its free end suspended over the other fixed electrode. The amount of current through the vacuum gap between the electrodes is determinative of acceleration since the current is an exponential function of the distance between the electrodes and the distance between the electrodes changes linearly with acceleration.

International Classification:

H04L 29/06
H04L 29/12
H04L 12/24

Abstract:

A processing system having at least one processor may obtain domain name system (DNS) traffic records of a DNS platform, the DNS traffic records associated with a source device having a first status and that is submitting DNS queries, where a first-tier DNS authoritative server of the DNS platform is configured to forward the DNS queries from the source device to at least a first second-tier DNS authoritative server of the DNS platform designated for the first status. The processing system may further detect anomalous DNS traffic records from the DNS traffic records, identify a change of the source device from a first status to a second status, based upon the detecting the anomalous DNS traffic records, and reconfigure the first-tier DNS authoritative server to redirect the DNS queries from the source device to at least a second second-tier DNS authoritative server designated for the second status.

Abstract:

A nanoimprint system and methods for separating imprinted substrates with nano-scale patterns from mold for manufacturing. Generally, the system includes means to create, monitor, and control relative movement between the mold and substrate for separation. It is capable of controlling where and when the separation happens and finishes. The relative movement may be generated by motion stages, springs, stage driven flexures, inflatable O-rings, gas flow, and other mechanical means. It may be monitored by separation force, overhead camera, and vacuum/pressures in different area of the system. The relative movement may be any combination of stages movements and movement sequences. The separation speed, direction, and force can be well controlled in the system to achieve fast and reliable separation between mold and substrate, and at the same time maintain the pattern shape and details on the consolidated imprint resist.
