International Classification:

G01V 3/00

US Classification:

324307

Abstract:

A method for magnetic resonance imaging (MRI) is provided. A scanning path is specified. Gradient amplitude is determined as a function of arc-length along the scanning path in k-space. A time optimal gradient waveform for scanning the scanning path is calculated from the gradient amplitude. The scanning path is scanned using the time optimal gradient waveform.

US Classification:

345 13, 345419, 345427

Abstract:

Two or more display components are used to provide spatially correlated displays of 3D content. Three-dimensional content is rendered on multiple displays where the 3D content refers to the same virtual 3D coordinates, in which the relative position of the displays to each other determines the 3D virtual camera position for each display. Although not required, one of the displays may be mobile, such as a cell phone, and the other stationary or nomadic, such as a laptop. Each display shows a view based on a virtual camera into 3D content, such as an online virtual world. By continuously sensing and updating the relative physical distances and orientations of each device to one another, the devices show the user a view into the 3D content that is spatially correlated. Each device has a virtual camera that uses a common pool of 3D geometrical data and renders this data to display images.

International Classification:

H04N 7/00

US Classification:

348142

Abstract:

Linear and rotational speeds of a mobile device are calculated using distance estimates between imaging sensors in the device and objects or scenes in front of the sensors. The distance estimates are used to modify optical flow vectors from the sensors. Shifting and rotational speeds of the mobile device may then be calculated using the modified optical flow vector values. For example, given a configuration where the first imaging sensor and the second imaging sensor face opposite directions on a single axis, a shifting speed is calculated in the following way: multiplying a first optical flow vector and a first distance estimate, thereby deriving a first modified optical flow vector value; multiplying a second optical flow vector and a second distance estimate, thereby deriving a second modified optical flow vector value; the second modified optical flow vector value may then be subtracted from the first modified optical flow vector value, resulting in a measurement of the shifting speed.

International Classification:

US Classification:

717174, 710 2

Abstract:

An adaptor for a peripheral device port includes non-volatile memory attached to the port using a port splitter or hub. The non-volatile memory is typically used for storage of peripheral device specific information such as device drivers and users' guide. Said adaptor provides necessary software as well as reference documents without any additional connection. A host computer sees an additional storage device in addition to a target peripheral device. This eliminates the need for CD or DVD devices for software installations or reference documents. Said adaptor can be easily integrated into a target device or cable for simpler usage.Furthermore, the required software such as device driver can be automatically installed using an auto-run program. This gives a greater convenience to the users since the peripheral device virtually ready for use out of the box without manual software installation.

International Classification:

G09G 5/08

US Classification:

345158

Abstract:

A handheld device having a display and a front-facing sensor and a back-facing sensor is able to render 3D content in a realistic and spatially correct manner using position-dependent rendering and view-dependent rendering. In one scenario, the 3D content is only computer-generated content and the display on the device is a typical, non-transparent (opaque) display. The position-dependent rendering is performed using either the back-facing sensor or a front-facing sensor having a wide-angle lens. In another scenario, the 3D content is composed of computer-generated 3D content and images of physical objects and the display is either a transparent or semi-transparent display where physical objects behind the device show through the display. In this case, position-dependent rendering is performed using a back-facing sensor that is actuated (capable of physical panning and tilting) or is wide-angle, thereby enabling virtual panning.
