« U-M offers open-access automated cars to advance driverless research | Main | BMW’s ReachNow car sharing expands to Brooklyn, launches pilot programs for new mobility services » >Automotive Grade Linux (AGL), a collaborative open source project developing a Linux-based, open platform for the connected car, announced five new members have joined Automotive Grade Linux and The Linux Foundation. AGL has close to 90 members representing various business interests, from semiconductors and in-vehicle software to IoT and connected cloud services. The newest AGL members include: Audiokinetic, Sasken Communication Technologies, Star Lab, Toyota Tsusho Corporation and Witekio. The AGL Unified Code Base (UCB) distribution was built from the ground up by a broad community of automakers, suppliers and technology companies. The in-vehicle infotainment platform is suited for deploying navigation, communications, safety, security and connectivity.The third release of the UCB will be on display at CES 2017; details will be shared later this year. The industry is beginning to realize that an open platform can lead to tangible business results and significantly reduce production times, development costs and improve product design. We’ve seen tremendous growth over the past year, and we plan to build on that momentum with the next release of the AGL Unified Code Base later this year.

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. The audio coder further compares the computed short-block characteristics to a set of threshold values to detect presence of an attack in each of the short-blocks and changes the long-block frame length of one or more short-blocks upon detecting the attack in the respective one or more short-blocks.

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.

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.

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.
