  • Patent number: 8754972
    Abstract: A module for high speed image processing includes an image sensor for generating a plurality of analog outputs representing an image and a plurality of HDDs for concurrently processing the plurality of analog outputs. Each HDD is an integrated circuit configured to process in parallel a predetermined set of the analog outputs. Each channel of the HDD can include an AFE for conditioning a signal representing one sensor analog output, an ADC for converting a conditioned signal into a digital signal, and a data formatting block for calibrations and formatting the digital signal for transport to an off-chip device. The HDDs and drive electronics are combined with the image sensor into one package to optimize signal integrity and high dynamic range, and to achieve high data rates through use of synchronized HDD channels. Combining multiple modules results in a highly scalable imaging subsystem optimized for inspection and metrology applications.

  • Publication number: 20140158864
    Abstract: A method of operating an image sensor with a continuously moving object is described. In this method, a timed delay integration mode (TDI-mode) operation can be performed during an extended-time illumination pulse. During this TDI-mode operation, charges stored by pixels of the image sensor are shifted only in a first direction, and track the image motion. Notably, a split-readout operation is performed only during non-illumination. During this split-readout operation, first charges stored by first pixels of the image sensor are shifted in the first direction and second charges stored by second pixels of the image sensor are concurrently shifted in a second direction, the second direction being opposite to the first direction.

  • Patent number: 8659427
    Abstract: A personal digital key (e.g., which can be carried by a human) contains a memory having different service blocks. Each service block is accessible by a corresponding service block access key. As the personal digital key (PDK) moves around, it is detected by sensors. The sensors report position data, thus enabling location tracking of the PDK. The sensors also provide a data path to various applications. An application that has access to a service block access key can therefore access the corresponding service block on the PDK. The sensors themselves may also contain service block access keys.

  • Publication number: 20130219186
    Abstract: A system and method provide efficient, secure, and highly reliable authentication for transaction processing and/or access control applications. A personal digital key (PDK) is programmed using a trusted programming device to initialize and/or register the PDK for use. In one embodiment, the initialization and registration processes are administered by a specialized trusted Notary to ensure the processes follow defined security procedures. In a biometric initialization, the programming device acquires a biometric input from a user and writes the biometric data to a tamperproof memory in the PDK. In registration, the Programmer communicates to one or more remote registries to create or update entries associated with the user PDK. Once initialized and registered, the PDK can be used for various levels of secure authentication processes.

  • Patent number: 8457672
    Abstract: Wireless client devices within a wireless network exchange data with other wireless devices during particular time slots determined by the network. More particularly, the system generates and wirelessly broadcasts synchronization information to the client devices, where the synchronization information contains individual masks to be applied to bit fields of individual client devices, where said time slots are determined in accordance with the masked bit fields. In such a manner, client devices can be coordinated to communicate with the system in a dynamic real-time tiered manner.
