09/966059

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 1200

US Classification:

711108, 711206, 365 49

Abstract:

A method of managing free entries in a CAM using virtual page pre-fetch is defined. The memory locations in a CAM are partitioned into multiple virtual pages (VP). The allocation of memory location to VPs is independent of the physical address of the location. The address of an empty location (free entry) from each VP is pre-fetched and is maintained in a free entry list. Consecutive write operations are scheduled in different VPs to avoid a back-to-back write in the same VP which eliminates resource contention. When data is retrieved from a location in the CAM, that location becomes available for next write. Because the allocation of a location to VPs is independent of the physical address of the location, when the location becomes available, a new VP assignment is made for that location.

International Classification:

H04N 5/232
H04N 5/14
H04N 5/235

Abstract:

A battery-powered camera includes a system processor configured to operate in a standby mode or a full-power mode. While operating the system processor in the standby mode, the camera detects an event in a field of view of the camera; records, using an image sensor of the camera, a plurality of image frames corresponding to the field of view in which the event was detected; stores in a frame buffer the plurality of image frames; and wakes the system processor from the standby mode. While operating the system processor in the full-power mode, the camera processes the plurality of image frames stored in the frame buffer using the system processor; and provides the processed image frames for streaming.

Abstract:

Examples of the present disclosure describe systems and methods for an auto-focus tool for multimodality image review. In aspects, an image review system may provide for the display of a set of medical images representing one or more imaging modalities. The system may also provide an auto-focus tool that may be used during the review of the set of medical images. After receiving an instruction to activate the auto-focus tool, the system may receive a selection of an ROI in at least one of the images in the set of medical images. The auto-focus tool may identify the location of the ROI within the image and use the identified ROI location to identify a corresponding area or ROI in the remaining set of medical images. The auto-focus tool may orient and display the remaining set of medical images such that the identified area or ROI is prominently displayed.

G02B 5/00
G01S 17/10

Abstract:

An optical device includes a substrate and an optical transmitter, which is mounted on the substrate and includes an optical emitter, which is configured to emit a beam of optical radiation, and a transmission lens assembly, which is configured to direct the beam along a transmit axis toward a target. An optical receiver is mounted on the substrate alongside the optical transmitter and includes an optical sensor and an objective lens assembly, which is configured to focus the optical radiation that is reflected from the target along a receive axis onto the optical sensor. An optical baffle is disposed asymmetrically relative to the transmit axis and has an asymmetrical shape configured to block preferentially stray radiation emitted from the optical transmitter toward the receive axis.

International Classification:

H04L 12/58
H04L 29/08

Abstract:

Techniques and systems are described to determine levels of competency of users as part of an online community and control generation of subsequent digital content to be used interaction of the online community with the users based on this determination. In one example, determination of the level of competency is based on relevance to topics of the online community. In another example, a determination is made as to whether the topic of the online community is stable before using user competency scores to control generation of subsequent digital content. In a further example, users of the online community are identified as exhibiting dormant or non-dormant behavior and used as a basis to control generation of subsequent digital content. In yet another example, user competency scores are adjusted based on a decay factor to address dormancy of users over a period of time.
