Instant help security system for emergency help using 2G, 2.5G and 3G cellular wirelesses half duplex call

Abstract: A security system (52) using cellular wireless half duplex communication call (62) is provided. The security system (52) comprises a set of monitored resources (10), group of owners (48) and group of helpers (50) connected using said cellular wireless half duplex call (52). The monitored resource (10) is configured to generate an alarm and is coupled with said cellular wireless half duplex call (62). Said owners (48) and helpers (50) are also coupled with said cellular wireless half duplex call (62). In an event of emergency said monitored resource (10) generates an alarm and initiates said cellular wireless half duplex call (62) to connect to said owners (48) and said helpers (50) in shortest possible time without significantly contributing to cellular network load. Said security system (52) provides most scalable, efficient and viable security solution using cellular wireless networks.

Bring your own device system using a mobile accessory device

Abstract: A BYOD solution using a combination device is described. This combination device is comprised of an employee owned smart mobile device (31) and an accessory device (32) used together using a wireless local area network (46). Mobile device (31) is an employee owned device that is used as a remote display of display output of enterprise certified applications (49) executing at accessory device (32). Accessory device (32) is comprised of a general purpose processor, optional graphics processing unit, one or more local wireless area network interfaces that connect the mobile device (31) to accessory device (32), and one or more Internet network interfaces (52) that connect accessory to enterprise network. The BYOD accessory device acts as a secure hardware gateway to connect the mobile device to corporate network. The BYOD accessory device also acts as a secure execution environment of corporate applications in addition to providing secure storage of corporate data.

Smartphone for interactive television

Abstract: A mobile device (34) capable of processing real time broadcast television signals (36) is described. Television signals (36) are received by mobile device (34) and converted to desired digital video content (47) format and then combined with output of software applications (43) running at mobile device (34) to create a combined television signal (51) that can be displayed by a television (37). Combined television signal is sent to television (37) to enable a user (48) to interact with television content using software applications (43) executing at mobile device (34).

User authentication system leveraging human ability to recognize transformed images

Abstract: An authentication system combining human image recognition capability to recognize transformed images, image transform element ( 41 ), and image storage element ( 38 ), and image display element ( 40 ), is implemented to enable user ( 32 ) to access a secure resource ( 31 ). Said authentication system provides a mass market solution that does not require expensive capital to implement and cannot be compromised as other authentication methods in prior art.

Cellular phone in form factor of a conventional audio cassette

Abstract: A hands free cellular phone system combining a full featured cellular phone with a form factor of a conventional audio cassette is provided. Several embodiments enabling real time interactive multimedia applications are also provided. Said hands free cellular phone system comprises a cellular phone device ( 1 ) in form factor of a conventional audio cassette ( 9 ). Device ( 1 ) can be inserted into any conventional audio cassette player ( 22 ) to transfer audio content into conventional audio cassette player ( 22 ) by using electromagnetic coupling with electromagnetic transducer ( 28 ) of said device ( 1 ) and electromagnetic transducer of conventional audio cassette player ( 35 ). Said device ( 1 ) provides a full featured, forward compatible, low installation cost hands free cellular phone system.

Abstract: A mobile terminal including a body; a touchscreen provided to a front and extending to side of the body and configured to display content; and a controller configured to detect one side of the body comes into contact with one side of an external terminal, display a first area on the touchscreen corresponding to a contact area of the body and the external terminal and a second area including the content, receive an input of moving the content displayed in the second area to the first area, display the content in the first area, and share the content in the first area with the external terminal.

Portable electronic device and method of controlling same

Abstract: A method includes displaying information associated with a first application on a touch-sensitive display, detecting a touch on a touch-sensitive display and determining touch attributes, determining when the touch is a first gesture type based on the touch attributes, and when the touch is determined to be the first gesture type, forwarding information related to the touch to a second application, otherwise forwarding the information related to the touch to the first application.

Devices, Methods, and Graphical User Interfaces for Accessibility Using a Touch-Sensitive Surface

Abstract: An accessibility method is performed by an electronic device with a display and a touch-sensitive surface. The method includes: displaying a plurality of user interface elements on the display; in response to detecting a first user interface navigation gesture by a finger on the touch-sensitive surface, navigating in the plurality of user interface elements in accordance with a current navigable unit type; in response to detecting a first user interface navigation setting gesture on the touch-sensitive surface: changing the current navigable unit type from the first navigable unit type to a second navigable unit type; and outputting accessibility information about the second navigable unit type; after changing the current navigable unit type, in response to detecting a second user interface navigation gesture by the finger on the touch-sensitive surface, navigating in the plurality of user interface elements in accordance with the current navigable unit type.

Mobile terminal and control method thereof

Abstract: A mobile terminal and a control method thereof, which can obtain an image, are provided. A mobile terminal (100) includes a camera unit (121), a pictogram extraction unit (182) and a controller (180). The camera unit (121) obtains image information corresponding to at least one of a still image and a moving image. The pictogram extraction unit (182) extracts at least one pictogram from the obtained image information. The controller (180) detects information related to the extracted pictogram, and displays the detected information to be overlapped with the obtained image information. In the mobile terminal, the controller (180) includes, as the detected information, at least one of previously recorded information and currently searched information related to the extracted pictogram.
