Abstract: Wireless access equipment provides access to a data network, such as the Internet, through a cellular communication system. A command receiver receives commands from terminal equipment in accordance with an interface protocol, which may be a dial-up protocol. A first access point identifier is stored in an APN store. When a session setup command is received, an APN controller selects between the first and a second access point identifier in response to a parameter of the session setup command. For example, the session setup command may comprise an access point identifier overriding the stored first access point identifier. A session controller proceeds to set up a packet data session of the cellular communication system to the data network using the selected session access point identifier. Embodiments of the invention may provide a flexible and user friendly means of supporting a plurality of network access points through a cellular communication system.

Abstract: A device with single MCU-based motion detection, local alarm and supervisory arrangement for alarm system controlled by an alarm control panel (ACP) is disclosed. The device includes a sensor component to monitor environment, an output component to generate warning messages, a power supply component to provide power, and a microcontroller to communicate with sensor component, drive output component and monitor the status of ACP. The device can detect when intruders break in and make alarm warnings even when the ACP is destroyed. Plurality of devices and said ACP form a local warning matrix network (LWMN) to increase the detection area and scary effect to intruders. Each device of LWMN works independently when the ACP is destroyed.

Abstract: A camera module and method for focusing a tunable lens configured to continuously vary its optical power in response to a drive signal. A drive circuit generates the drive signal so that the tunable lens performs a continuous scan of its optical power. An image sensor is configured to acquire light images passing through the tunable lens, and to convert the light images to image signals during the continuous scan. A processor is configured to generate focus scores of the acquired light images using the image signals during the continuous scan. The processor is configured to determine from the focus scores a peak focus score achieved or achievable, and to instruct the drive circuit to adjust the drive signal so that the tunable lens settles at a value of the optical power that corresponds to the peak focus score.

Abstract: A system for tracking and locating surgical items and objects in an operating room environment that incorporates two-stage functionality. A first stage provides mechanisms for tracking objects using radio frequency (RF) tags that are positioned on or in conjunction with every surgical item and object so as to be tracked by a number of RF transceivers located about the operating room. In addition to integrating RF ID components, the tags integrate hard spherical components that are easily identifiable by ultrasonic detection. If an object is “lost” from the tracking system functionality (RF tracking), the system operator may review a last known location and movement path presented on a display and thereafter utilize an ultrasonic sub-system in a localized area to detect the exact location of the missing object or item. Narrowing the location of a “lost” object is facilitated by the use of one or more LED laser pointers that are directed through the last known path of the object and to its last known location.

Abstract: Embodiments of a method for using a microreactor to produce biodiesel. For example, the method may comprise flowing a first fluid comprising an alcohol and a second fluid comprising an oil to the microreactor. Alcohols typically, but not necessarily, are lower aliphatic alcohols, including methanol, ethanol, amyl alcohol or combinations thereof. Biodiesel production can be under supercritical conditions, where such conditions typically are determined relative to the alcohol component. Suitable sources of oil products include soy, inedible tallow and grease, corn, edible tallow and lard, cotton, rapeseed, sunflower, canola, peanut, safflower, and combinations thereof. Catalysts can be used to facilitate biodiesel production, such as metal oxides, metal hydroxides, metal carbonates, alcoholic metal carbonates, alkoxides, mineral acids and enzymes. Oil conversion to biodiesel typically increases with increasing mean microreactor residence time.

Abstract: An electronic mail file access system (100) and associated methods permit a person (102) who originates or maintains a file to allow a person (198) authorized to view or edit a file to access the file by transmitting an electronic message to the file accessor. The file manager can conveniently select whether the file accessor will be able to modify the file or just view it. A file manager can grant one or more accessors viewing or editing access to a file (or multiple files) through transmission of a common electronic message, or through transmission of a separate message for each file or accessor. Variations and methods with different advantageous features are also described.

Abstract: An articulated bench comprising a two-section pad and two folding/pivoting support leg assemblies attached to a frame. A length-adjustable (telescoping) dual tubular brace assembly folds out of the frame from beneath the pivoting padded section (i.e. the section for supporting the upper body) and is inserted into one of a series of catches located on the section's rear surface to hold it at a selectable incline. Improved pivoting support leg assemblies include primary foot cross-bars, and secondary foot crossbars each fixedly attached to a leg to either provide lateral floor-support when the support legs are locked in the inwardly stowed position, or alternatively serve as a hand holds or foot rests when the legs are deployed for performing exercises, thereby allowing a broader range of positions and much greater utility.
