摘要： An integrated illumination apparatus includes a light injection portion having a first end for receiving light from a light source. The light injection portion includes material that supports propagation of said light along the length of the light injection portion. Turning microstructure is disposed on a first side of the light injection. The turning microstructure is configured to turn at least a substantial portion of light incident on the first side and to direct the portion of the light out a second opposite side of the light injection portion. A slit is disposed along the length of the light injection portion. The slit forms an optical interface on the second opposite side of the light injection portion that provides total internal reflection for light propagating along the length of the light injection portion to be guided therein. The optical interface further transmits light turned by said turning microstructure. A light distribution portion is disposed with respect to the slit to receive the light turned by said turning microstructure and transmitted out of the second side of the light injection portion and through said slit. At least one bridge is disposed between light injection portion and the light distribution portion. The bridge mechanically connects the light injection portion to the light distribution portion.

摘要： A method includes sending a first redirect instruction to a first client in response to a first session request received at a service address, and establishing a first session with the first client in response to a second session request received at the first redirect address indicated by the first redirect instruction. Additionally, the method includes determining a first service interval has passed, and sending a second redirect instruction to a second client in response to a third session request received at the service address after the first service interval has passed. The method still further includes establishing a second session with the second client in response to the fourth session request received at the second redirect address indicated by the second redirect instruction after the first service interval has passed, and rejecting the fifth session request received from a third client at the first redirect address after the first service interval has passed.

摘要： A sequence layer in a machine-learning engine configured to learn from the observations of a computer vision engine. In one embodiment, the machine-learning engine uses the voting experts to segment adaptive resonance theory (ART) network label sequences for different objects observed in a scene. The sequence layer may be configured to observe the ART label sequences and incrementally build, update, and trim, and reorganize an ngram trie for those label sequences. The sequence layer computes the entropies for the nodes in the ngram trie and determines a sliding window length and vote count parameters. Once determined, the sequence layer may segment newly observed sequences to estimate the primitive events observed in the scene as well as issue alerts for inter-sequence and intra-sequence anomalies.

摘要： A conditioning unit can allow the blower to be easily translated from a first operable position in the conditioning unit to a second operable position external to the conditioning unit. The translation of the blower does not require the disconnection of the blower and, accordingly, does not require that the blower be disconnected and reconnected to the control system. Such capability can facilitate the installation of the conditioning unit into a variety of applications and allows the purchaser to customize the blower location based on the desired performance. The ability to customize the installation of the conditioning unit without requiring disconnection and reconnection of the blower can reduce the cost and expense associated with the installation into differing applications.

摘要： Techniques are described for detecting anomalous events using a long-term memory in a video analysis system. The long-term memory may be used to store and retrieve information learned while a video analysis system observes a stream of video frames depicting a given scene. Further, the long-term memory may be configured to detect the occurrence of anomalous events, relative to observations of other events that have occurred in the scene over time. A distance measure may used to determine a distance between an active percept (encoding an observed event depicted in the stream of video frames) and a retrieved percept (encoding a memory of previously observed events in the long-term memory). If the distance exceeds a specified threshold, the long-term memory may publish the occurrence of an anomalous event for review by users of the system.

摘要： Various embodiments of the present invention relate to enhancing the brightness of displays that employ illumination systems. In some embodiments, the illumination systems include light guides, diffractive microstructure, and light-turning features. The diffractive microstructure may be configured to receive ambient light at a first angle and produce diffracted light at a second angle greater than the first angle and greater than the critical angle for of light guide. The light is thereby guided within the light guide. The light-turning features may be configured to turn the light guided within the light guide out of a light guide and onto, for example, a spatial light modulator at near normal incidence.
