Abstract: The present invention relates to a method and apparatus for human detection in images taken from a surveillance camera. In one embodiment, the method comprises subtracting a current image from a baseline image to obtain a delta image, said delta image comprising at least one object; filtering stray noises and/or noise clusters from said delta image; marking and traversing the boundary of said at least one object; determining the at least one object as valid object: if a length traversed along the boundary of said at least one object is greater than a pre-determined threshold value; and if an interior region of said at least one object is detected as being solid; erasing the interior region of said at least one object and determining one or more pre-determined points on the boundary of said valid object; determining one or more pre-determined parameters corresponding to said pre-determined points and ratio thereof; processing the ratios to identify if the object is a human being or not.

Abstract: A method for controlling a display of unsuitable video content is described. The method provides for control of any unsuitable video content as perceived by the user and display of alternative video content of user's choice, at the press of a dedicated button, on a remote controller, of a device controlling the video display. The original video stream may be resumed by a second press of the same dedicated button on the remote controller. The method includes a provision for alternative ways of programming alternative video content in the device that controls the video display. When multiple options for alternative video content exist, a choice may be configured through the settings of the device controlling the video display. The method also provides for resumption of original video content, by the press of the said button on a remote controller or by the expiry of a timer configured through settings of the device controlling the video display system.

Abstract: 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.

Abstract: The present invention provides a computationally efficient technique for compression encoding of an audio signal, and further provides a technique to enhance the sound quality of the encoded audio signal. This is accomplished by including more accurate attack detection and a computationally efficient quantization technique. The improved audio coder converts the input audio signal to a digital audio signal. The audio coder then divides the digital audio signal into larger frames having a long-block frame length and partitions each of the frames into multiple short-blocks. The audio coder then computes short-block audio signal characteristics for each of the partitioned short-blocks based on changes in the input audio signal.

Abstract: A remotely controlled biometric based mechanism for security systems includes a remote security lock and uses an Onsite Controller (OC) and a plurality of Remote Controllers (RCs). 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 inputs. Randomized selection of a subset of controllers (RCs) who operate the lock is performed. 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. A measure for determining the security level is also included, where the measure chosen is the number of controls that need to be broken to gain access to the controlled resource.

Abstract: A method and circuit for high-speed current switching includes altering the operating voltage of the Current Source using a resistor in non-transmission mode, turning parasitic capacitive coupling into an advantage for faster settling of CS gate bias voltage. The resistor is designed to compensate for the voltage coupling when the Current Source is switched to Transmit mode. This greatly improves the settling time of current and bias voltage of the Current Source transistor without adding any complex circuit and saves 100% of power consumed in non-transmit mode.

Abstract: Embodiments herein provide a method and system for synchronization in a Wireless Communication Network using a new frame, Synchronization Frame (SF), and a configurable length of the same that is transmitted from a Network Controller (NC) to the Network Elements (NEs) in the network. The periodicity of the SF could be changed, to align with the data exchange periodicity, while still keeping synchronization. The length of the SF is made configurable to achieve this effect. It is directly proportional to the period, with which it needs to be transmitted, i.e., a larger delay between two SFs is achievable through the use of a larger SF frame size. This method provides a mechanism in which synchronization between the NC and NEs is achieved by listening to only a part of the SF, which is constant in size. This method also provides tolerance to failure by using acknowledgement schemes.

Abstract: 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.

Abstract: The present invention provides a technique for retrieving pictures from a large database that is less complex and uses significantly less memory and computational resources than current techniques. This is accomplished by determining representative data vectors based on a tolerance distance that represents data vectors in a given vector space that defines the picture to extract features of the picture that facilitates in retrieving pictures.

Abstract: 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.
