Certain example embodiments described herein relate to techniques for test automations in emergent systems. More particularly, certain example embodiments provide a mechanism for dynamic recognition of combinations of services/components, monitoring of their real-time usage, and automatic generation and running of tests for the combinations at appropriate times (e.g. when part of a combination is updated). The tests for individual (and, if available, combinations of) services are associated with the services using a registry. A taxonomy or ontology can be used to denote the semantics of the services, providing an array of options for assessing how and when to run tests and actions. It also is possible to detect similar combinations of services automatically. It therefore becomes possible to automate the detection and running of tests for a combination of services/components, even in emergent systems where such combinations cannot always be predicted in advance and where services/components are addable/modifiable over time.

One embodiment sets forth a technique for ensuring relaxed coherency between different caches. Two different execution units may be configured to access different caches that may store one or more cache lines corresponding to the same memory address. During time periods between memory barrier instructions relaxed coherency is maintained between the different caches. More specifically, writes to a cache line in a first cache that corresponds to a particular memory address are not necessarily propagated to a cache line in a second cache before the second cache receives a read or write request that also corresponds to the particular memory address. Therefore, the first cache and the second are not necessarily coherent during time periods of relaxed coherency. Execution of a memory barrier instruction ensures that the different caches will be coherent before a new period of relaxed coherency begins.

Described is a technology by which a GPU-based photon mapping mechanism/algorithm uses a kd-tree to render arbitrary dynamic scenes. For each frame, the mechanism emits and traces a set of photons into the scene. When a photon hits a surface, it can either be reflected, transmitted, or absorbed based on the surface material. Once photon tracing is done, a kd-tree is built for the stored photons. To estimate the radiance value at an arbitrary surface point, the k-nearest photons are located and filtered. The photon tracing and photon kd-tree construction, as well as the radiance estimation using k-nearest neighbor (KNN) searches are performed on graphics hardware, e.g., a GPU. In one example, only caustic photons are traced, whereby a photon is terminated and stored once it hits a diffuse surface.

The unlocking device (2) comprises an unlocking module for starting the lock head to move, an identity identifying module (201) and a communication module. The identity identifying module (201) of the unlocking device identifies the identity of the lock, receives an identity label information which is transferred from the identity and state converting module (104) of the lock, recognizes the state of the lock tongue (102), and judges whether to unlock the lock or not according to the identity identification logic and state identification logic of the lock which are received from the logic generator (3). The smart interlock system works flexibly and enables electric anti-misoperation to be reliable and intelligent.

A key fob includes a biometric sensor including a fingerprint area sensor having a surface for receiving a finger, and a controller includes at least one processor configured to authenticate a user of the key fob based on biometric information obtained with the biometric sensor and stored biometric information for an individual. The key fob includes a RF transmitter for communicating stored transaction information to a reader upon authentication of the user and a housing. The housing includes a base for supporting the biometric sensor and a cover sleeve slidably engaged with the base to allow for extension from and retraction into the sleeve by the base, thereby permitting selective exposure of the fingerprint area sensor under user actuation.

One axial end of a through-hole of a bearing portion of a first stationary core located on a movable core side has a peripheral edge placed at a corresponding axial position. The corresponding axial position of the peripheral edge may be the same as an axial position of an axial end surface of a radially outer part of the first stationary core or is on an axial side of the axial end surface, which is axially opposite from the movable core. A bottom portion of a yoke may have a hole, which receives at least a part of a second stationary core. A stopper made of a resin material may be placed on a side of the bottom portion of the yoke, which is opposite from the second stationary core in the axial direction. A shaft may be abuttable against the stopper.

A phase frequency detector realizes a highly linear conversion from noise-shaped ΣΔ modulation into charge quantities without degradation of phase-locked loop (PLL) phase noise. The phase frequency detector may feature a construction of an Up signal output and a Down signal output, in which the Up signal rises when a divided VCO input rises, an Up signal falls when the divided VCO input falls, a Down signal rises when the divided VCO input rises, and a Down signal falls when a reference input rises. A mode selection input may be utilized for a fast lock-up PLL.
