Abstract: An electronic device such as a cellular telephone may be used to gather pointing input from a user. During operation, the electronic device may be held by a user. Orientation information such as information on an orientation of the electronic device relative to an external surface may be gathered using a camera, accelerometer, compass, gyroscope, or other orientation sensor. The gathered input may serve as pointing input for use in drawing visual elements such as lines in content being projected onto the external surface or content being displayed using displays. Pointing input and other input may also be used to select displayed items and take other actions. Displays for displaying image content may form part of an electronic device being held by the user, a desktop device, or other devices. A steerable projector may be used in displaying projected images such as images containing content based on pointing input.

Abstract: Techniques for inverse text normalization are provided. In some examples, speech input is received and a spoken-form text representation of the speech input is generated. The spoken-form text representation includes a token sequence. A feature representation is determined for the spoken-form text representation and a sequence of labels is determined based on the feature representation. The sequence of labels is assigned to the token sequence and specifies a plurality of edit operations to perform on the token sequence. Each edit operation of the plurality of edit operations corresponds to one of a plurality of predetermined types of edit operations. A written-form text representation of the speech input is generated by applying the plurality of edit operations to the token sequence in accordance with the sequence of labels. A task responsive to the speech input is performed using the generated written-form text representation.

Abstract: A method and apparatus are provided for performing acquisition, synchronization and cell selection within an MIMO-OFDM communication system. A coarse synchronization is performed to determine a searching window. A fine synchronization is then performed by measuring correlations between subsets of signal samples, whose first signal sample lies within the searching window, and known values. The correlations are performed in the frequency domain of the received signal. In a multiple-output OFDM system, each antenna of the OFDM transmitter has a unique known value. The known value is transmitted as pairs of consecutive pilot symbols, each pair of pilot symbols being transmitted at the same subset of sub-carrier frequencies within the OFDM frame.

Abstract: A device provides user interfaces for a messaging application. The device receives a first message and displays a representation of the first message, where the first message is scheduled to be deleted upon satisfaction of expiration criteria. The device displays an affordance for keeping the first message. In accordance with a determination that the affordance was selected prior to the satisfaction of the expiration criteria, the device keeps the first message. In accordance with a determination that the expiration criteria has been satisfied without detecting selection of the affordance, the device ceases to display the representation of the first message on the display.

Abstract: An occurrence of one or more “care events” is detected by an electronic device monitoring environmental data and/or user data from one or more sensors. The electronic device transmits one or more alerts regarding the detected occurrence to at least one other electronic device. In some cases, the electronic device may cooperate with at least one other electronic device in monitoring, detecting, and/or transmitting. For example, the electronic device may detect the occurrence based on sensor data received from a cooperative electronic device or such data in combination with the electronic device's sensor data. By way of another example, the electronic device may detect the occurrence and signal a cooperative electronic device to transmit one or more alerts.

Abstract: User equipment (UE) can include processing circuitry configured to decode radio resource control (RRC) signaling from a base station, the RRC signaling indicating a transmission coding scheme for a physical uplink shared channel (PUSCH) transmission. PUSCH-to-phase tracking reference signal (PT-RS) energy per resource element (EPRE) ratio is determined using the RRC signaling. A PT-RS power boosting factor is determined based on the transmission coding scheme and the PUSCH-to-PT-RS EPRE ratio. The PT-RS is encoded for transmission using a plurality of PT-RS symbols, the transmission using increased transmission power corresponding to the PT-RS power boosting factor. The RRC signaling further includes a flag enabling the PT-RS transmission. The PUSCH-to-PT-RS EPRE ratio is 00 or 01, and the transmission coding scheme is a codebook-based uplink transmission or non-codebook-based uplink transmission.
