  • Publication number: 20220375886
    Abstract: A semiconductor device has a semiconductor die and an encapsulant deposited over the semiconductor die. A first conductive layer is formed with an antenna over a first surface of the encapsulant. A second conductive layer is formed with a ground plane over a second surface of the encapsulant with the antenna located within a footprint of the ground plane. A conductive bump is formed on the ground plane. A third conductive layer is formed over the first surface of the encapsulant. A fourth conductive layer is formed over the second surface of the encapsulant. A conductive via is disposed adjacent to the semiconductor die prior to depositing the encapsulant. The antenna is coupled to the semiconductor die through the conductive via. The antenna is formed with the conductive via between the antenna and semiconductor die. A PCB unit is disposed in the encapsulant.

  • Patent number: 11500837
    Abstract: Performance of optimizations to correct duplicate, missing, or other user-induced errors in hierarchical data storage may be automated. Relationships between items may be used to determine whether a modification should be made to items. Once identified, a determination may be made as to whether the modification will impact query performance. If so, then permission may be obtained before the modification is made. If not, then the modification may be made automatically.

  • Patent number: 10152175
    Abstract: Techniques are disclosed for selective area scanning, touch scanning, and/or reporting of touch screen contacts in electronic touch sensitive devices. The selective area scanning can be used to only scan a specific section of a touch screen area, the selective touch scanning can be used to scan only for specific touches or input sources on a touch screen, and the selective reporting can be used to selectively report only desired contacts to a device processor and reject all other contacts. Multiple selective scan areas can be provisioned, with each discrete area customizable with respect to location, size, accepted touch types and/or reporting criteria. In some cases the user can configure some or all of these selective screen features.

  • Patent number: 9864655
    Abstract: Methods and apparatus are provided for providing testing as a service. A loading computing device can receive a request to restore a testing computing device to a known software configuration. The loading computing device, after receiving the request to restore the testing computing device, can restore the testing computing device by at least: obtaining a software image storing the known software configuration, where the software image includes security-context data having security contexts associated with the plurality of software components, and where a particular security context can have an identity, a role, and a domain or type; storing at least part of the obtained software image onto the testing computing device, and after storing at least part of the obtained software image onto the testing computing device, setting security contexts for the obtained software image stored on the testing computing device using the security-context data.

  • Publication number: 20160352812
    Abstract: A system includes a processor which has access to a representation of model of activity, which includes workspaces. Each workspace includes domain hierarchies for representing an organizational structure of the collaborating users using the system, and initiatives hierarchies representing process structures for accomplishing goals. An interface permits users to view and modify the workspaces for which the user has access. Each user can have different access permissions in different workspaces. The domain and initiative hierarchies provide two views of the workspace objects without duplicating resources. A resource is a collection of shared elements defined by the users that give users associated with the workspace access to information sources. Users can define knowledge boards for creating reports based on information fields of the resources. The knowledge board is associated with a resource template from which the resource is created.

  • Patent number: 9293054
    Abstract: Computer implemented systems and methods of communicating a system reaction to environmental input comprising receiving environmental input, determining a hazard state and a user state from the environmental input, determining a system reaction from the hazard state and the user state and communicating the system reaction to a user interface. In some embodiments, the system reaction comprises a system reaction level and in some embodiments the system reaction level corresponds to a stage of automation. In some embodiments, the user interface is a multimodal interface and in some embodiments the user interface is a haptic interface.

  • Patent number: 9250681
    Abstract: A system and method for improving power consumption by providing the ability to detect whether a cover is placed on top of Infrared, IR, touch device. While the cover is in the open state, a certain amount of the light transmitted by the IR transmitters is directed upward and away from the IR receivers in the device. When the cover is closed, this light is reflected off of the cover and is incident on the IR receivers. The system of the present invention recognizes this increased level of received IR light and determines that the cover is in a closed position. Having made such a determination that the cover is placed on the device, the device's power savings system can switch to an appropriate power saving mode.

  • Patent number: 9134849
    Abstract: A system and method that allows pen input and touch input to better co-exist during writing on a touch screen device, such as a tablet device. If the pen/stylus is detected as present and is pointed at the surface, inputs initiated by a user's finger (or other) touch are rejected and pen inputs are allowed. If the pen is detected as present, but is pointed away from the writing surface of the touch screen, stylus/pen inputs are rejected and touch inputs are allowed. If pen is not detected as present, the system ignores all pen inputs. Erasing functions are also provided. The size of the eraser can be made proportional to the pressure level, contact size or signal level of the pen or the user's finger performing the erasing.
