Abstract:

A beam steering module comprised of a mirror stack array in close proximity to a collimator array controllably steers photons along two axis and in a direction substantially less than 90 degrees to the collimator orientation. Several configurations of the module are described using single and double axis mirror rotation and relay optics. Optical telecommunications switches are shown using modules coupled to each other along flat and curved surfaces, with and without use of fold mirror and enabling a plurality of configuration options including photodetector optical power monitoring schemes that require no external power taps.

Abstract:

This disclosure describes, in part, techniques for managing access to a fleet account of mobile electronic devices. For instance, an administrator of a business and educational institution may place an order with an offering service to purchase a large number of eBook reader devices. The offering service identifies that the business and educational institution is ordering a fleet of devices. Furthermore, each of the devices ordered are associated or registered to a managed or fleet account controlled by the administrator of the business and educational institution. The techniques described herein prevent an individual user of a fleet device from de-registering the device from the managed account, and also allow an account administrator to alter preferred settings of the managed account. Further, techniques are described for allowing a user of a device to opt-in or associate their device with the account.

Abstract:

Systems and methods are described for avoiding redundant data transfers using delta coding techniques when reliably and opportunistically communicating data to multiple user systems. According to embodiments, user systems track received block sequences for locally stored content blocks. An intermediate server intercepts content requests between user systems and target hosts, and deterministically chucks and fingerprints content data received in response to those requests. A fingerprint of a received content block is communicated to the requesting user system, and the user system determines based on the fingerprint whether the corresponding content block matches a content block that is already locally stored. If so, the user system returns a set of fingerprints representing a sequence of next content blocks that were previously stored after the matching content block. The intermediate server can then send only those content data blocks that are not already locally stored at the user system according to the returned set of fingerprints.

International Classification:

G06F 3/06

Abstract:

A device and method generates a graphical representation for memory leak detection. The method includes executing a selected application for a time period. The method includes determining a plurality of memory application programming interface (API) functions performed during the execution of the selected application in the time period. Each of the memory API functions request a chunk of a memory of the electronic device at a specified time. The method includes determining select ones of the memory API functions that do not release the respective chunk of the memory in the time period. The method includes generating the graphical representation including the selected memory API functions at the respective specified time for identification of a memory leak of the selected application.
