  • Patent number: 9412340
    Abstract: Some embodiments enable a first electronic device (e.g., a notebook computer) to obtain state information directly from another electronic device (e.g., a smartphone) so that the first electronic device may replicate a state of content of the other computing device. This is useful when a user of an electronic device desires to switch between one device and another device such that the user may continue an activity (e.g., playing a video game) on another device without having to restart the activity. This is also useful when a user of a first electronic device attempts to replicate the state of the activity on a second device from another user such that both users may participate in the same activity. In some embodiments, a user of a device may obtain content from a server and state information from another device to replicate the state of content on the other device.

  • Patent number: 9295420
    Abstract: A transmission-reflectance swappable Raman device and a method thereof are disclosed. The excitation light is selectively directed to the sample in one direction for generating the transmission Raman signal in transmission mode or in another direction for generating the reflectance Raman signal in reflectance mode. The content of an analyte in a sample can be determined by analyzing transmission and reflectance Raman signal.

  • Patent number: 9285863
    Abstract: Power savings is provided to users of various electronic devices by monitoring the times and locations at which those users activate, deactivate, or otherwise change an operational state of one or more functional elements of a device. Other contextual or environmental information can be captured as well when the user performs such an action. One or more statistical analysis or prediction algorithms can be used to determine when and/or where the user is likely to repeat the one or more actions, where a confidence level of the prediction can be impacted at least in part by the environmental and contextual factors. When a prediction has a minimum level of confidence, a corresponding action can be performed automatically by the device when the relevant factors are met. Changes in behavior can be monitored such that the predictions can be refined over time.

  • Patent number: 9076008
    Abstract: Some embodiments enable a user of an electronic device to selectively secure applications and/or content of the electronic device. For instance, certain embodiments enable a user to password protect applications (e.g., email, calendar, contacts, photos) within a single environment. In some embodiments, a user can selectively secure specific content (e.g., work-related email messages, personal emails, work-related calendar entries, corporate contacts) within an application. Further, some embodiments enable a user to specify which applications and/or types of content the user would like to password protect. For instance, a user that has sensitive work-related information stored on or accessible through the user's device may choose to password protect work-related applications (e.g., work email account) and content (e.g., work documents, work-related calendar entries).

  • Publication number: 20150177834
    Abstract: A low distraction interface can be provided for an electronic device by monitoring information such as a gaze direction of a user. A device can be configured to only display information to a user when the user is looking substantially toward the device, and can be configured to present that information in a way that is of minimal distraction to others nearby. The user can control aspects of the display by looking away from the device, continuing to look at the device for a period of time, or otherwise providing input without physically interacting with the device. Such an approach can be beneficial for settings such as business meetings where a user might want to obtain information from the device but does not want to appear inconsiderate by picking up and checking information on the device.

  • Patent number: 9027465
    Abstract: A holder and method for obtaining a holder, wherein the holder is provided with a first and a second wall part. The first and second wall part are interconnected such that therebetween at least a first storage space, at least a first fluid connection and at least a first seal removable through fluid pressure and defining an opening are formed. The at least first removable connection is communication with the first storage space and seals a communication to or from the at least first fluid connection. With the method for obtaining the holder, prior to forming the connection of the first and second wall parts, a lacquer is locally applied to one of the first and second wall parts, which after connection results in a controlled reduced adhesion for obtaining the at least first removable seal. Here in the proximity of the removable seal, an additional connection of the first wall part to the second wall part is provided.

  • Patent number: 8879060
    Abstract: A Raman signal detection and analyzing system and a method thereof are disclosed. The Raman signal is generated by emitting an excitation light to a sample. The Raman signal is then modulated by passing through a plurality of optical filter and modulator. The resulting modulated Raman signal comprises two orthogonal components, which intensities are to be computed based on the first harmonic of said modulated Raman signal. The content of a specific analyte within the sample can then be determined based on the ratio of the intensities of the two components.

  • Publication number: 20140280081
    Abstract: Systems, methods, and computer-readable storage media are provided for utilizing part-of-speech (POS) tagging of both the words included in a search query and the words included in potential search result documents to improve query alteration accuracy and search result ranking. Upon receiving a search query, POS tags are assigned to the words comprising the query to create query word-tag pairs. The query word-tag pairs are utilized to reformulate the query and are compared with document word-tag pairs included in a plurality of potential search result documents to determine a degree of similarity. The degree of similarity is utilized as an input in scoring and/or ranking the relevance of the potential search result documents with respect to one another.

  • Patent number: 8743051
    Abstract: An electronic device automatically reverses a left-right orientation of content displayed by the device when detecting that a user is viewing content of the device via a mirror. Some embodiments reverse the content upon detecting a trigger such as a reflection of an image displayed by the device, indicating that the device is displaying content against a mirror. In some embodiments, the device reverses the content upon detecting that blinking markers displayed by the device are inverted or upon detecting a blinking marker flashing in a particular pattern consistent to that emitted by the device. Some embodiments reverse the content upon detecting both the reflection of the image and a reflection of the user. Further, some embodiments reverse the content upon determining that the user is facing a mirror and switches back to its normal orientation when the user is viewing the content by directly looking at the device.
