Appl. No.:

12/901872

International Classification:

G06F 12/00

US Classification:

711155, 711E12001

Abstract:

A memory device and related techniques are provided to modify data stored in the memory device without the need to send the data to an external device. A command is received at the memory device to modify data stored at a memory location in a memory array of the memory device. The command includes a value to be used for modifying the data. The memory device reads data from the memory location. The data read from the memory location is modified with modify circuit in the memory device based on the value obtained form the command to produce results data. The results data produced by the modify circuit is written back to the memory location. Since the memory device does not need to send the data read from the memory array off-chip to another device, referred to herein as a host device, to update the data, the input/output bandwidth of the bandwidth is substantially reduced, allowing for lower power memory device operation and reduced latency.

Abstract:

A single deactivation device is used to deactivate both harmonic type EAS markers and magnetomechanical type EAS markers. The deactivation device includes a housing, and a permanent magnet and a coil disposed within the housing. The coil is circular and is arranged concentrically with, and outside of, the permanent magnet. The permanent magnet forms a DC magnetic field for deactivating the harmonic type marker by magnetizing control elements thereof. The coil is driven to generate an AC magnetic field that deactivates the magnetomechanical type marker by degaussing a control element thereof. The maximum amplitude of the AC magnetic field is lower than the level of the DC magnetic field, and is substantially below the coercivity of the control elements of the harmonic type marker. The coercivity of the control element of the magnetomechanical type marker is low enough to be degaussed by the AC magnetic field.

Abstract:

Embodiments are directed to sound source rendering in a virtual reality (VR) system that executes an immersive virtual environment including at least one virtual sound source. A motion sensor to produces a measurement of a motion of the user, and an imaging sensor is used to produce an indication of at least one physical feature of the user relevant to sound perception. A sound rendering engine determines and applies a head-related transfer function (HRTF) based on the at least one physical feature of the user, and effects a source direction of sound from the at least one virtual sound source according to a frame of reference of the user based on the motion of the user.
