Sierra Entertainment, Inc. is an American video-game developer and publisher founded in 1979 as On-Line Systems by Ken and Roberta Williams. Based in Oakhurst, California and later in Fresno, California, the company is owned by Activision, a subsidiary of Activision Blizzard.Sierra is best known today for its multiple lines of seminal graphic adventure games started in the 1980s, many of which proved influential in the history of video games. The Sierra label was absorbed by its parent company in 2008. Some franchises that were published by Sierra will be published by Activision. On August 7, 2014, Sierra's website was re-activated, with a new logo and a message saying "More to be revealed at Gamescom 2014." Wikipedia.

An electronically-controlled steerable beam antenna with suppressed parasitic scattering includes a feed line defining an axis x; and first and second arrays of electronically-controlled switchable scatterers distributed along the axis x, each of the scatterers in the first and second arrays being switchable between a high state and a low state to scatter an electromagnetic wave propagating through the transmission line so as to form a steerable antenna beam. Each of the scatterers of the second array is configured to be 180-phase-shifted relative to a corresponding scatter of the first array. The switchable scatterers of the first and second arrays are configured into high states and low states relative to each other so as to suppress parasitic scattering of the electromagnetic wave without suppressing the steerable antenna beam.


An imaging system for a moving vehicle aggregates pre-existing data with sensor data to provide an image of the surrounding environment in real-time. The pre-existing data are combined with data from one or more 3-D sensors, and 2-D information from a camera, to create a scene model that is rendered for display. The system accepts data from a 3-D sensor, transforms the data into a 3-D data structure, fuses the pre-existing scene data with the 3-D data structure and 2-D image data from a 2-D sensor to create a combined scene model, and renders the combined scene model for display. The system may also weight aspects of data from first and second sensors to select at least one aspect from the first sensor and another aspect from the second sensor; wherein fusing the pre-existing scene data with the sensor data uses the selected aspect from the first sensor and the selected aspect from the second sensor.


A cyber-security device provides secure communications bi-directionally between an external network and an internal network including a supervisor control and data acquisition (SCADA) device. The device includes a processor in data communication with the external and internal networks, the processor being programmed with a rule-set establishing validation criteria configured to validate data received from the external and internal networks. The processor is operable in an operational mode to pass between the external and internal networks only data that are compliant with the validation criteria. The processor is re-programmable with a new rule-set only in a programming mode. The device includes a switch that is manually operable to switch the processor from the operational mode to the programming mode.

The processor is operable in an operational mode to pass between the external and internal networks only data that are compliant with the validation criteria. The processor may be configured to save certain validated data indicating a system state that can inform the application of the rule-set to data. The processor is re-programmable with a new rule-set only in a programming mode. The device includes a switch that is manually operable to switch the processor from the operational mode to the programming mode.

A medical data point of care device is configured to collect, access, store, and distribute patient medical data. The device is particularly suited for use in a mobile environment and may be particularly useful in an urgent care mobile environment, such as a battlefield or disaster area. In such environments, data transmission services may be intermittent and the bandwidth of such services may be low. The device is configured to adjust the flow of data transmission from a point of care location to a remote location so as to maximize or otherwise increase the likelihood of successful transmission of the data. The device is further configured to collect data from both a care provider and a medical device.

A software application enables a user (such as for example a medical care provider) to acquire, enter, view, and store data related to medical care and/or transport of a patient. The software application enables one or more care providers to acquire and enter data in a timely manner beginning at the time medical care commences until a later time, such as until disposition of the patient at a medical care facility.

A semantic database is generated to provide answers to questions by users. Text processors can receive text from text sources, and can convert the text into intermediate logical statements. The text processors can then convert these statements into unambiguous semantic representations. A semantic database connected to the text processors can store the semantic representations. Query processors connected to the semantic database can receive a question from a computing device operated by a user, and can convert the question into intermediate logical subqueries. The query processors can then use a disambiguation table to generate unambiguous semantic subqueries from these intermediate logical subqueries. Using the semantic database, the query processors can match each semantic subquery to the stored semantic representation, and join results of the matching as appropriate, to determine one or more answers to the question. The query processors can send the one or more answers to the computing device.

Disclosed is a winglet radome assembly, which can include at least one antenna assembly that can send and receive signals, such as radio waves. Some implementations of the winglet radome assembly can be secured to a wing of an aircraft, such as a fixed-wing aircraft. In addition, the winglet radome assembly can be configured to secure to a distal end of the wing and can be securely adapted to a variety of aircraft.
