20130120324 | System and Method for Simulating Stiff Bristle Brushes Using Stiffness-Height Parameterization - A method, system, and computer-readable storage medium for simulating bristle brush behavior in an image editing application may use stiffness-height parameterization to determine the height of a brush tool above a canvas during a brush stroke. The determination may be dependent on the pressure applied during the stroke (e.g., using a stylus on a pressure-sensitive tablet), and on the stiffness of the brush bristles. The system may select a standard-stiffness or high-stiffness mapping between stylus pressure values and brush height values dependent whether the bristle stiffness value is above or below a pre-determined threshold. The standard-stiffness mapping may apply a linear function to pressure values to determine height values. Using the high-stiffness mapping, the effect of increased pressure on corresponding brush height values may be reduced as bristle stiffness is increased. Adjusting pressure-to-height mapping based on stiffness may allow the system to realistically mimic the behavior of stiff bristle brushes. | 05-16-2013 |
20130120385 | Methods and Apparatus for Diffuse Indirect Illumination Computation using Progressive Interleaved Irradiance Sampling - Methods and apparatus for diffuse indirect illumination computation using progressive interleaved irradiance sampling.

The digital painting application (or simulation module) may provide a small set of physically meaningful parameters (e.g., canvas wetness, drying rate, and pickup mix ratio). By setting the values of these parameters (or overriding default values for a selected paint type), the user may better control the appearance of brush strokes made by a virtual paint brush on a digital canvas. For example, the length of a brush stroke, the amount of streaking caused by paint picked up during the brush stroke, and/or the mix of paint deposited from a pickup buffer and a reservoir buffer of a brush model may be affected by changing the values of these parameters, thus allowing users to create different realistic painting effects. | 05-16-2013 |

The application may support two non-uniform paint loading modes, e.g., one that fills the brush with a distribution of paint matching a single sample, and one that fills the brush with paint continuously as it is swept over the canvas. Non-uniform paint loading may be applied to stamp-based brush models and/or bristle brush models. | 05-16-2013 |

The techniques may be implemented in procedural painting algorithms that employ a vector-based, fluid motion simulation technique to help achieve dynamic, serendipitous behaviors of painting at good interactive rates even on relatively low-powered devices. Instead of employing polygons in a procedural painting algorithm that are combinations of pigment and water, a technique may be employed in which the polygons are separated into pigment polygons and water polygons. The water polygons are not rendered; only the pigment polygons are rendered. To improve the performance of the wetness determination at vertices of the pigment polygons, a technique may be used that first rasterizes all of the water polygons into a buffer, which may be referred to as a wetness layer or wetmap; the wetness at a vertex is then determined by sampling this buffer or layer at the vertex's position. | 05-23-2013 |

A context aware trigger, power aware trigger, a randomly scheduled wakeup trigger, a deterministically scheduled wakeup trigger, and/or a predictively scheduled wakeup trigger can be utilized to determine the availability of contexts associated with the target action. Based on the availability of a context that should be available, one or more target actions are automatically executed and/or selectively suspended. | 08-06-2015 |
20150223028 | Broadcast/Multicast Used for M2M/MTC - A method, an apparatus, and a computer program product for wireless communication are provided. An apparatus notifies a user equipment (UE) of an upcoming multicast/broadcast of data intended for receipt by a group of UEs assigned a machine type communication (MTC) class. The UE has one or more MTC classes assigned to it and is configured to awake for the upcoming multicast/broadcast of data if the data to be broadcast corresponds to an MTC class assigned to the UE. The apparatus also multicasts/broadcasts the data intended for receipt by a group of UEs through at least one multicast/broadcast mechanism. | 08-06-2015 |
20160057700 | APPARATUS AND METHODS FOR LOW POWER SENSING OF WIRELESS ACCESS TECHNOLOGIES - Apparatus and methods for low power sensing of wireless access technologies are disclosed. In particular, a mobile wireless device, such as an access terminal, may utilize a lower power circuitry portion that operates at a lower power than active circuitry, such as a primary transceiver. The lower power circuitry portion includes a configurable searcher that is capable of sensing if signals of one or more various wireless access technologies are present. When the wireless device utilizes sleep or idle modes for power savings, use of the lower power sensing circuitry to sense the presence of wireless access technologies, rather than using an awoken higher power primary transceiver for sensing, affords increased power savings. An added ability of the lower power circuitry to be put into sleep or idles modes achieves even greater power savings. | 02-25-2016 |

20080228923 | Server-Side Connection Resource Pooling - A server side connection pool provides pooling of server connections. Thus, client side processes do not create groups of dedicated resources. Clients are provided the capability to communicate to a server side connection broker process to GET a pooled server connection comprising connection state plus a thread of execution for doing some work, whereby requesting the work can bypass the connection broker process and go directly to the assigned pooled connection. Once the client issues a RELEASE to release the pooled connection back to the pool, a completely different client process on potentially a different client middle tier machine can reuse the same pooled connection. The server-side connection pool can be logically partitioned into sub-pools that correspond to connection classes that typically correspond to respective applications. A client process can request a pooled connection having a particular state, where a stored procedure can be executed to generate such state. | 09-18-2008 |
20080275896 | PRESERVING USER CODE IN OTT-GENERATED CLASSES - An object type translator (OTT) determines one or more database object types. The one or more database object types are mapped to a first structural language type definition code. After being generated, the user may add user code to the first structural language type definition code. During regeneration of these files, the first structural language type definition code is then parsed to determine the user code that has been added, based on the start and end markers that the user code segments have been marked with. OTT maps these user-code segments to the corresponding database types and keeps track of the mapping and the user code. When the OTT starts generating the second structural language code, the OTT determines a position where the user code should be inserted into the second structural language type definition code using that mapping. The user code is then inserted in the second structural language code in the position determined. Accordingly, the user code that was added is not lost when the structural language type definition code is regenerated from the one or more database object types. | 11-06-2008 |
20110307615 | METHOD AND MECHANISM FOR IMPLEMENTING TAGGED SESSION POOLS - An improved method, mechanism, and system for implementing, generating, and maintaining for implementing session pools is disclosed. A session in a session pool can be customized to with a specific set of affinities and attributes. Tags can be associated with the customized sessions. When a later request is made for a session having a set of desired characteristics, the tags can be used to search for and identify a session in the session pool having the requested characteristics. Also disclosed is a method, mechanism, and system for dynamic sizing of session pools. | 12-15-2011 |
20140281252 | STATEMENT CACHE AUTO-TUNING - Disclosed are methods and apparatuses that implement automatic resizing of statement caches in response to cache metrics. One embodiment provides an approach for periodically calculating a session eligibility index for each session cache, wherein the session eligibility index indicates the priority level of the session cache for resizing, and selecting and resizing one or more cache sessions based at least in part on the session eligibility index. | 09-18-2014 |
20150324259 | METHOD AND SYSTEM FOR AUTOMATIC FAILOVER FOR CLIENTS ACCESSING A RESOURCE THROUGH A SERVER USING HYBRID CHECKSUM LOCATION - Some embodiments are directed to a method and apparatus for implementing an automatic failover mechanism for a resource. A client accesses a source through a first server using a first session. During the session, the client stores checksum information corresponding to data received via the session with the first server. When it is detected that the session between the first server and the client has failed, the client is automatically connected with second server that has access to the resource. The checksum information is transmitted from the client to the second server, where it is compared with checksum information calculated at the second server, so that a determination can be made as to whether the client can continue processing where it left off when connected to the second server. | 11-12-2015 |
