摘要:
A method for interoperable communications including at least the step of: a) at least one radio user's being able to transmit at least one transmission on a first radio frequency to a computer having at least one sound card and at least two sound card channels on one or more sound cards, wherein each of the at least two sound card channels is programmed to receive and process transmissions from at least two separate radio frequencies. This configuration creates a new way of interfacing virtually any speaker with virtually any computer, and allows a paradigm shift of communications organization such that everyone can talk at once, literally, and still “hear” everyone else.

A receiver (300) includes a mixing digital-to-analog converter (DAC) (118A), a direct digital frequency synthesizer (DDFS) (132) and a dynamic element matching (DEM) circuit (304). A DAC of the mixing DAC (118A) is implemented as a segmented DAC having a thermometer encoded DAC section (120A) and a binary encoded DAC section (120B). The DDFS (132) includes outputs configured to provide bits associated with a digital LO signal to inputs of a switching section (124A: 124B) of the mixing DAC (118A). The DEM circuit (304) is coupled between the outputs of the DDFS (132) and the inputs of the switching section (124A) that are associated with the thermometer encoded DAC section (120A). The DEM circuit (304) is configured to scramble the bits provided to the thermometer encoded DAC section (120A).

Multi Media Integrated Imaging (MMII) includes methods, devices and systems that are effective in overcoming the shortcomings of conventional medical imaging techniques. Instead of generating a series of unrelated images taken at different times and obtained by several technologies, embodiments of the present invention generate a deeply detailed, coherent image taken simultaneously with several imaging modalities. In this manner, each three-dimensional coordinate point in the image is enriched by the different data provided by each of the plurality of imaging technologies employed. The data for each three-dimensional coordinate point is taken in each of the imaging modalities at a same point in time such that that the simultaneous capture of the multi-modality image data provides a crisp snapshot of the patient's internal structures.

An improved technique for processing a DHCP request from a DHCP client device is performed in a data communications device of a network (e.g., performed in a router). The technique involves receiving the DHCP request from the DHCP client device, evaluating a set of rules in response to the DHCP request to obtain a rule-based classification result, and outputting a DHCP response in response to the rule-based classification result. In some arrangements, a policy manager which is external to the data communications device plays a role in the classification process (e.g., dynamic updating of the set of rules, responding to individual queries from the data communications device when generating the rule-based classification result, etc.). Such improvements over conventional DHCP approaches enables improved flexibility and coordination of the DHCP process.

An aircraft (1000) includes multiple servicing levels (1014, 1016) and a flight deck level (1040) that is isolated from the servicing levels (1014, 1016). An aircraft security system (1001) includes a passive system (1030) and an active system (1032) that is in operation with said passive system (1030). The passive system (1030) includes a service opening (1050) for both passengers and cargo and the flight deck (1040) that is isolated from the service opening (1050).
摘要:
A computer-implemented method for controlling user access to secured data resources includes a step of inventorying data resources that are to be secured. Thereafter, a requirements data structure may be generated that includes one element mapped to each of the inventoried data resources, each element being configured to store a requirement value that is set according to an authorization level necessary to access the mapped data resource. For each user to have access to any of the inventoried data resources, a grant data structure may be defined that includes one element mapped to each of the plurality of data resources, each element being configured to store a grant value that is set according to an authorization granted to the user to access the mapped data resource. When a user request for access to at least one of the secured data resources is received, a step may be carried out to compare the grant and requirements data structures. Access may then be disallowed by the received user request to any secured data resource that is mapped to any element of the requirements data structure whose requirement value is greater than the grant value of a corresponding element of the grant data structure. In the comparing step, the grant and requirements data structures may be truncated to include only elements mapped to inventoried data resources to which the user request requests access.

A film dispenser for a stretch wrapping apparatus is provided. The film dispenser includes a pre-stretch assembly having a top portion mounted to and extending downwardly from a drive plate of a roll carriage frame. The pre-stretch assembly includes two pre-stretch rollers having first ends connected to the roll carriage frame and second ends connected to one another. The pre-stretch rollers may be coated. The pre-stretch assembly further includes a cantilevered idle roller mounted to the drive plate and positioned between the pre-stretch rollers. A film path is defined by the space between the pre-stretch rollers and the idle roller. The film path is easily accessible via the bottom end of the pre-stretch assembly.

A device for tracking an item or a box may include a conductive mesh configured to at least partially cover the item or the box, and a wireless tag coupled to the conductive mesh. The wireless tag may be configured to report a breaching of the conductive mesh or an opening of the box by issuing a first predetermined RF signal. The wireless tag may include a GPS device and the first predetermined signal may include GPS-derived geographical information.

A modular data center, for housing and cooling electronic equipment, includes multiple housings, a first portion of the housings configured to hold heat-producing electronic equipment and a second portion of the housings configured to hold at least one cooling unit, each of the housings of the first portion having a front and a back and configured to hold the heat-producing electronic equipment such that gas is drawn into the equipment from fronts of the equipment, heated by the equipment to become heated gas, and expelled by the electronic equipment is expelled through the backs of the housings, where the housings are disposed and coupled to form a laterally-enclosed arrangement laterally enclosing a hot region and defining a top opening allowing gas to vertically exit the hot region, and where backs of the housings of the first portion are disposed adjacent to the hot region such that the heat-producing equipment, when mounted to the housings, will expel the heated gas into the hot region.
摘要:
A system for monitoring a selected physiological activity of a person includes a passive wireless tag including a sensor for monitoring the selected physiological activity of the person and a Radio Frequency Identification (RFID) tag coupled to the sensor. The RFID tag may include a unique identifier and may be configured to, when polled, generate, store and transmit a monitoring signal representative of the selected physiological activity and of the RFID tag unique identifier. A monitoring and processing station may be configured to poll the passive wireless tag and to receive and process the monitoring signal transmitted from the passive wireless tag.
