The processing circuitry communicates synchronization information to the second wireless, reader device and portable wireless device. The superframe is used to synchronize a wireless data exchange between the third wireless, reader device and the portable wireless device.

Abstract: Photon or electron detectors may include polycrystalline silicon resistive gates with voltage gradients applied to reduce lag and improve operating speeds. The polycrystalline silicon resistive gates may be doped polycrystalline silicon which is heavily doped with donor atoms or acceptor atoms and ion-implanted with an electrically inactive species. The electrically inactive species may be implanted in a pattern to form multiple ion-implanted regions with different resistivities. The ion-implanted regions are formed in select patterns to control the resistivity of the polycrystalline silicon resistive gates and to modify the lateral electric field across the differentially-biased polycrystalline silicon resistive gate. The X-ray detectors may also include a circuit element with a current-mode differential connection to improve clock feedthrough and power dissipation characteristics.

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.

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.

Abstract: A method of treating or preventing a neuroinflammatory and/or neurodegenerative disease in a subject by administering a pharmaceutically effective amount of a CB2 receptor agonist is described. The CB2 receptor agonist can be a compound according to formula I or a pharmaceutically acceptable salt thereof, with R1 and R2 as defined herein. Administration of the CB2 receptor agonist activates CB2 receptors in the microglia, and can restore synaptic plasticity, cognition, and memory in subjects having elevated levels of amyloid-? peptide in the brain.

Abstract: A method for imaging overlay targets on a wafer includes (1) using a sensor to acquire images of overlay targets on a wafer while the wafer is in motion and (2) accelerating and decelerating the wafer to move the overlay targets into alignment with the sensor between acquiring images of the overlay targets. Accelerating/decelerating the wafer may include: (1) accelerating the wafer at a maximum acceleration and then decelerating the wafer at a maximum deceleration, (2) accelerating/decelerating the wafer in a triangular waveform pattern, (3) accelerating/decelerating the wafer in a sinusoidal pattern, or (4) accelerating/decelerating the wafer in a near-sinusoidal pattern (created by combining a pure sinusoidal profile with one or more harmonic profiles). A system is also provided for implementing the above method(s).

Abstract: A cooking appliance that includes a heating element, a controller, and a dock, each mounted to a panel. The cooking appliance also includes a user interface which is removably mountable to the panel, so that the user interface can be used separated from the cooking appliance. The controller is configured for detecting a proximity of the user interface relative to the panel. Further, the controller is configured for deactivating the heating element in response to the detected proximity of the user interface relative to the panel passing a deactivation threshold.

Abstract: A system and method provide efficient, secure and highly reliable authentication for transaction processing and/or access control applications in which only biometric input is required from the user. A Personal Digital Key stores a biometric profile that comprises a representation of physical or behavioral characteristics that are uniquely associated with an individual that owns and carries the PDK. The PDK wirelessly transmits the biometric profile over a secure wireless transaction to a Reader for use in a biometric authentication process. The Reader compares the received biometric profile to a biometric input acquired at the point of transaction in order to determine if the transaction should be authorized.
