    摘要: A cost effective digital image capture apparatus such as a digital camera that operates in both still mode and video mode, using a common programmable image processing chain and fixed optics. The full resolution of the image sensor (yielding raw image data) may be used in still mode, with adequate signal-to-noise ratio (SNR) achieved either from the scene ambient lighting or from supplemental light supplied by a strobe. In video mode, the apparatus may be configured to capture video image data by programming the parameters for image processing methodologies such as scaling, decorrelation, and encoding into a look-up table (LUT) which in turn configures logic circuitry to spatially scale and compress if necessary the raw image data in order to meet storage and transmission bandwidth constraints for video images. In video mode, adequate SNR may be achieved despite the lower light conditions, encountered, for example, during videoconferencing, by averaging pixels together during scaling.

    摘要: For a particular request to access a resource, both a user associated with the request and a service through which the request is made are identified. Whether requested access to a resource is permitted is determined based on a user associated with the requested access and a service through which the access is requested. This determination can be made based on an access control entry of an access control list corresponding to the resource, the access control entry identifying access to the resource that is permitted to the user when accessing the resource through the service.

    摘要: One aspect relates to a process and associated device that provides a private key of an asymmetric key pair in a key device. A symmetric master key is derived from the private key of the asymmetric key pair. The symmetric master key is stored in a computer memory location. The symmetric master key is used to encrypt or decrypt a file encryption key. The file encryption key can encrypt or decrypt files. In another aspect, the user can still access the files even if a user deactivates the key device by encrypting or decrypting the file encryption key directly from the symmetric master key.

    摘要: An infant care apparatus such as an incubator or infant warmer having a mattress for supporting the infant on an infant platform that can, at times, by fully rotated 360 degrees to obtain full access to the infant. In the incubator, a translation platform can be slid into and out of the infant compartment and the mattress tray is pivoted to that translation platform so as to rotate at a pivot point that connects the mattress tray to the translation platform. Accordingly, when all of the doors of the infant incubator are in the closed position, the mattress tray is constrained from rotational movement but that mattress tray can be rotated a full 360 degrees whenever both doors are open or when the translation platform has been moved to a position at least partially exterior of the infant compartment. In all, the apparatus provides easy and convenient access to the infant for carrying out procedures on the infant while it is still supported by the infant care apparatus.
