Abstract: An electronic device configured for real-time calibration of an on-board accelerometer. A plurality of acceleration measurements are collected from the accelerometer to form a data set. An accelerometer error correction model is maintained that includes bias error calibration parameters, sensitivity calibration parameters, and cross-axis calibration parameters that each specify respective weights for each of bias error, sensitivity error, and cross-axis error. Calibration values are determined for one or more of the bias error calibration parameters, the sensitivity calibration parameters, and the cross-axis error calibration parameters for the data set of acceleration measurements using the accelerometer error correction model. A true acceleration vector may be determined that corresponds to a subsequently received acceleration measurement using the determined calibration values.

Abstract: Some embodiments are directed to a vehicle door assembly that includes a vehicle door, which defines an interior and is connected to the motor by the linkage, such that actuation of the actuator engages the motor, which thereby moves the vehicle door via the linkage. The vehicle door assembly also includes a powered door override. At least a portion of the powered door override can be disposed within the interior of the vehicle door. The powered door override is configured to disconnect the linkage from the motor so as to isolate the motor from the vehicle door and thereby enable the vehicle door to be moved manually. An interior panel is connected to the vehicle door so as to cover at least a portion of the interior of the vehicle door, such that the powered door override is at least partially enclosed between the interior panel and the vehicle door.

Abstract: A method of image compositing that directly manipulates ray tracing samples generated by a ray tracing renderer, rather than manipulating the pixels of a rasterized image. Rasterization may be performed after compositing at any desired resolution or resolutions, for example to adapt to different displays. Ray tracing samples may be tagged with the identity of the object intersected by the ray, facilitating object selection during compositing without the need for object masks. Random or pseudo-random ray patterns typically used by renderers may be supported directly. A large number of compositing operations may be performed directly on the ray tracing samples, including color changes, object repositioning in two dimensions or three dimensions, merging of images or objects from different scenes or rendering passes, and generation of new viewpoints for an image. Preview images may be generated during compositing using a subset of the available samples, trading off image quality for speed.

Abstract: Apparatus and method for detecting unauthorized tampering with a data storage device having a housing and a memory. A first identifier value is stored on an external surface of the housing and a second identifier value is stored within the memory. The first and second identifier values are combined in a predetermined order to form a combined identifier value for which a digital signature is generated using a private key, and the digital signature is stored on the storage device. The digital signature, the first and second identifier values, and one or more dummy identification values are retrieved from the storage device and stored in a memory of a verification device, which combines the retrieved first and second identifier values in the predetermined order to generate a retrieved combined identifier value. The storage device is authenticated using the retrieved combined identifier value, the digital signature and a public key.

In response to the second user selecting the real-time contact option, the system communicates to the first user a real-time contact request and information identifying the second user.

Abstract: This is an engine that uses combustion pressures and shock waves to provide moment about an axis on a rotor producing a torque. This engine is a torque driven power plant which can be used for a variety of energy applications. At the core of this engine is a large diameter right cylinder that uses internal vectored combustion to rotate a shaft that can be attached to various mechanisms for use in diverse applications. This engine can be scaled to be various sizes with the functionality of the engine unaffected. This engine has a unique internal rotational-recoil disk (piston head type) that rotates in a circle making it extremely efficient. This engine has directional intake valves and removes the exhaust through the center of the rotation-recoil disk.

Abstract: Apparatus and method for data security in a data storage device. In some embodiments, an alternating pattern is written to a magnetic recording medium as a sequence of symbols at a selected clock rate. A repeatable magnetic signature is generated by reading the alternating pattern from the medium, the magnetic signature having relatively weak entropy at boundaries of the symbols. A multi-bit digital sequence is extracted from the repeatable magnetic signature, the digital sequence having relatively strong entropy. The digital sequence is stored in a separate memory coupled to the medium. Access to data stored on the medium is authenticated responsive to the digital sequence stored in the separate memory.

The method comprises obtaining, via the GUI, selection criteria provided by a user with respect to a provider of a service and initiating a communication with a provider that was automatically selected based on the selection criteria. The method further comprises obtaining a further input provided by the user and communicating the further input to the selected provider.

Abstract: Systems, methods, and apparatus for performing deduced reckoning navigation without a constraint relationship between orientation of a sensor platform and a direction of travel of an object are described herein. A sensor fusion component can be configured to receive data from sensors of a sensor platform coupled to a pedestrian; and generate world coordinate information based on the data. Further, a gait recognition component can be configured to record one or more walking patterns of the pedestrian in a training database; and determine whether the world coordinate information is associated with a walking pattern of the one or more walking patterns. Furthermore, a position estimation component can be configured to estimate a position of the pedestrian based on the world coordinate information if the world coordinate information is associated with the walking pattern, regardless of an orientation of the sensor platform with respect to the position of the pedestrian.

Abstract: Apparatus and method for data security in a data storage environment. In some embodiments, input data from a host is received into a buffer memory. Data compression is applied to the input data to provide compressed data. Encryption is applied to the compressed data to generate encrypted data, and the encrypted data are stored in a main memory of a data storage device. A system parameter value associated with the storage of the encrypted data is generated and stored in a memory, such as the main memory of the storage device. The system parameter value may include information relating to the compression of the data. A trusted relationship is established to authenticate the host responsive to a request for the updated system parameter value. The system parameter value is transferred to the host responsive to the established trusted relationship.

Abstract: Systems or methods can be used to detect evidence of tampering. The tampering can be physical tampering, such as the turning of a screw, or removal or modification of an electronic component. In some examples, a tamper detection value can be determined from a tamper detection device and compared to a predetermined tamper detection value to determine if tampering is indicated. The system can, upon detection of the tampering, halt an operation, disable device or circuit functionality, disable future operations, physically disable a device, or any combination thereof.

Abstract: Apparatus and method for secure data shredding in an imperfect data storage device. In some embodiments, a hash function is applied to multi-bit random sequence to generate an output hash. A combinatorial logic function logically combines the output hash with a secret to provide an output value. The random string is processed into a plurality of secret shares which are stored in a first location in a non-volatile memory and the output value is stored in a different, second location of the memory. The secret is subsequently shredded by applying an erasure operation upon the secret shares in the first location of the memory.
