Systems and methods are described for performing contactless gesture recognition for a computing device, such as a mobile computing device. An example technique for managing a gesture-based input mechanism for a computing device described herein includes identifying parameters of the computing device relating to accuracy of gesture classification performed by the gesture-based input mechanism and managing a power consumption level of at least an infrared (IR) light emitting diode (LED) or an IR proximity sensor of the gesture-based input mechanism based on the parameters of the computing device.

A thermal energy controller system useful in medical procedures includes a controller coupled to a probe, and a thermal element to vary probe temperature. The controller includes memory storing a non-continuous algorithm that permits user-selectable settings for various probe types such that controller operation is self-modifying in response to the selected probe setting. Probe output power Pout is constant in one mode to rapidly enable probe temperature to come within a threshold of a target temperature. The controller can then vary Pout dynamically using a proportional-integral-derivative (PID) algorithm Pout=Kp·P+Ki·I+Kd·D, where feedback loop coefficients Kp, Ki, Kd can vary dynamically depending upon magnitude of an error function e(t) representing the difference between a user-set desired target temperature and sensed probe temperature. Advantageously, target temperature can be rapidly attained without overshoot, allowing the probe system to be especially effective in arthroscopic tissue treatment.

An intrusion detection system (IDS) is capable of identifying the source of traffic, filtering the traffic to classify it as either safe or suspect and then applying sophisticated detection techniques such as stateful pattern recognition, protocol parsing, heuristic detection or anomaly detection either singularly or in combination based on the traffic type. In a network environment, each traffic source is provided with at least one IDS sensor that is dedicated to monitoring a specific type of traffic such as RPC, HTTP, SMTP, DNS, or others. Traffic from each traffic source is filtered to remove known safe traffic to improve efficiency and increase accuracy by keeping each IDS sensor focused on a specific traffic type.

RGB-Z imaging systems acquire RGB data typically with a high X-Y resolution RGB pixel array, and acquire Z-depth data with an array of physically larger Z pixels having additive signal properties. In each acquired frame, RGB pixels are mapped to a corresponding Z pixel. Z image resolution is enhanced by identifying Z discontinuities and identifying corresponding RGB pixels where the Z discontinuities occur. Thus segmented data enables RGB background substitution, which preferably blends foreground pixel color and substitute background color. The segmented data also enables up-sampling in which a higher XY resolution Z image with accurate Z values is obtained. Up-sampling uses an equation set enabling assignment of accurate Z values to RGB pixels. Fixed acquisition frame rates are enabled by carefully culling bad Z data. Segmenting and up-sampling enhanced video effects and enable low cost, low Z resolution arrays to function comparably to higher quality, higher resolution Z arrays.

This relates to an event sensing device that includes an event sensing panel and is able to dynamically change the granularity of the panel according to present needs. Thus, the granularity of the panel can differ at different times of operation.

One embodiment of the present invention includes a parallel processing unit (PPU) that performs pixel shading at variable granularities. For effects that vary at a low frequency across a pixel block, a coarse shading unit performs the associated shading operations on a subset of the pixels in the pixel block. By contrast, for effects that vary at a high frequency across the pixel block, fine shading units perform the associated shading operations on each pixel in the pixel block. Because the PPU implements coarse shading units and fine shading units, the PPU may tune the shading rate per-effect based on the frequency of variation across each pixel group. By contrast, conventional PPUs typically compute all effects per-pixel, performing redundant shading operations for low frequency effects. Consequently, to produce similar image quality, the PPU consumes less power and increases the rendering frame rate compared to a conventional PPU.

As the route is mapped out, a new map of the territory is created. As subsequent devices enter into that area (including navigational systems), the updated mapping information is provided to the device and can then be augmented by future location readings or can simply be used by the device.

The invention provides a USB storage device and an access control method thereof. An access control module is provided on the USB storage device. The storage space is divided into at least one data storage entity. Each user's access right to each data storage entity is set and stored in the USB storage device as an access control list. The process between the USB storage device's being connected with a USB host and its being disconnected from the USB host is one session. When a session is established, the user provides authentication information for the USB device to authenticate him / her, and saves the user information used in the current session. In the current session, when the host of the user issues an access request for the data storage entity on the USB storage device, the access control module queries the access right list based on the user information in the current session to determine whether the user has an access right to the requested data storage entity. When the user does not have the access right to the data storage entity, the access control module denies the user's access request for the data storage entity.
