WirelessComSoft, a software company based in India, provided research and development outsourcing support in an Intellectual Property strong wireless communication products and services space. Over a period, WirelessComSoft developed a robust information security infrastructure and complied with industry standard auditing procedures. However, implementing information security across its different world-wide sites, updating it in tune with evolving user needs, deploying robust business continuity architecture, and maintaining logical and physical isolation of clients' off-shore development centers were challenges that WirelessComSoft's security implementation team grappled with every day. The case presents how information security infrastructure at WirelessComSoft evolved, the challenges faced and the methods implemented by the information security team to overcome these challenges.

A multiparty controlled remote security lock is disclosed. The embodiments herein relate to security systems and, more particularly, to remotely controlled biometric based mechanisms in security systems. In order to operate the remote security lock at least one OC and a plurality of RCs are employed. Further, the OC is located at the site of the lock and the RCs may be located away from the site of the lock. The remote security lock employs 2-factor authentication mechanisms using smartcard access and biometric means. A method for randomized selection of a subset of controllers (RCs) who operate the lock is used. The randomization enhances the scalability of the system, while keeping the security strength of the system as that of choosing the full set of controllers for operating the lock.

The present invention provides an improved motion estimation encoder for digital video encoding applications. In one example embodiment, the improved encoder receives a raw image in the form of a current frame and estimates the macroblock motion vector with respect to a reference frame. The encoder then performs an initial local search around an initial motion vector candidate derived from spatio-temporal neighboring macroblock parameters. The encoder then compares the user-defined complexity scalable sum of absolute difference between the original and the associated reference macroblock against an adaptive threshold value for motion estimation convergence. The encoder introduces a global full search around a candidate from a coarser level, in case an initial local search fails. The encoder then selects an inter encoding mode for coding the current macroblock, when the first local search is successful, otherwise the encoder selects the inter or intra encoding mode for encoding the current macroblock by comparing variances of the original and difference macroblocks.

This invention relates to the field of vibration switches, and more particularly to vibration switches used for DC to DC switching conversion. DC to DC convertors use an electrical switch like MOSFET/transistor for conversion to switched DC. The MOSFET/transistor requires a power source for the switching action. A vibration switch comprising of metal or conductive polymer strip can be used for the switching action in a DC to DC convertor. The strip is bent by using a small weight attached to one end. When exposed to vibration beyond a certain threshold the metal strip oscillates and performs multiple switching operations by connecting to the contact terminal. The switched DC thus produced could be filtered to generate a DC output. This switch does not require power for operation. The vibration sensitivity and frequency of oscillations of the switch can be controlled using the hardness of the material used.
