The fuel system also includes an interface (110) to the portable computing device (120), wherein the interface (110) comprises a power link (112) that provides power to the portable computing device, and a bidirectional communication link (114) that provides bidirectional communication between the portable computing device and the controller for the fuel cell system.
Abstract:
Se revelan métodos y aparatos para corregir la distorsión de inclinación y/o perspectiva en dispositivos de captura de imagen. En algunas modalidades, el método puede incluir leer una medición de orientación asociada con la posición relativa del dispositivo de captura de imagen con respecto a un objeto, determinar si la medición de orientación es menor que un umbral y en el caso de que la medición de orientación sea menor que el umbral, corregir la imagen obtenida por el dispositivo de captura de imagen. En algunas modalidades, el aparato puede incluir un sensor de imagen, una memoria acoplada al sensor de imagen, un dispositivo de medición de orientación acoplado al sensor de imagen y un dispositivo de medición de distancia acoplado al sensor de imagen, en donde los datos de imagen pueden ser almacenado en la memoria junto con una medición del acelerómetro y junto con una medición del dispositivo de medición de distancia.
Abstract:
This relates to sensor systems, detectors, imagers, and readout integrated circuits (ROICs) configured to selectively detect one or more frequencies or polarizations of light, capable of operating with a wide dynamic range, or any combination thereof. In some examples, the detector can include one or more light absorbers; the patterns and/or properties of a light absorber can be configured based on the desired measurement wavelength range and/or polarization direction. In some examples, the detector can comprise a plurality of at least partially overlapping light absorbers for enhanced dynamic range detection. In some examples, the detector can be capable of electrostatic tuning for one or more flux levels by varying the response time or sensitivity to account for various flux levels. In some examples, the ROIC can be capable of dynamically adjusting at least one of the frame rate integrating capacitance, and power of the illumination source.
Abstract:
A stylus is disclosed. The stylus includes a shaft; a conductive tip at a distal end of the shaft; and control circuitry coupled to the conductive tip and configured to generate a modulated signal at the conductive tip to identify the stylus. The stylus can also include a switch coupled between the conductive tip and the shaft. The control circuitry can be further configured to control the switch to modulate a conductive path between the conductive tip and the shaft to generate the modulated signal.
Abstract:
Various embodiments of a wirelessly powered local computing environment are described. The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance D of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance D can be on the order of 1 meter or so.
