Abstract: This disclosure provides systems, methods and apparatus, for measurement and reporting procedures associated with a sidelink positioning reference signal (SL-PRS). In one aspect, a first user equipment (UE), which may function as a sidelink anchor node, may transmit an SL-PRS to a second UE in accordance with a slot format or structure that is dedicated for SL-PRS transmissions. The first UE may select resources for the transmission of the SL-PRS via sensing and exclusion or using a set of resources that are dedicated for SL-PRS transmissions. The second UE may receive the SL-PRS and use the SL-PRS to acquire positioning information, in accordance with an observed time difference of arrival (OTDOA)-based positioning method, or may transmit a second SL-PRS to the first UE to facilitate acquisition of positioning information at the first UE, in accordance with a round-trip-time (RTT)-based positioning method.

Abstract: Provided are a water-soluble Pd(II) complex, a synthesis method thereof and use thereof as a catalytic precursor. The complex has a chemical name, ammonium dinitrooxalato palladium (II), and a molecular formula of (NH4)2[Pd(NO2)2(C2O4)]·nH2O (n is the number of crystal water). The Pd(II) complex is synthesized by using PdCl2 or [Pd(NH3)2Cl2] as a starting material which is firstly converted into [Pd(NH3)4]Cl2 in ammonium hydroxide, followed by a chemical reaction between [Pd(NH3)4]Cl2 and excessive NaNO2 to produce trans-[Pd(NH3)2(NO2)2] via ligand substitution mechanism, and finally dissolving trans-[Pd(NH3)2(NO2)2] in an aqueous solution of oxalic acid leads to the formation of the target product (NH4)2[Pd(NO2)2(C2O4)]·2H2O. The complex does not contain chlorine and other elements that are harmful to a catalyst, is readily soluble in water and has a low thermal decomposition temperature.

Abstract: Described herein are various technologies pertaining to shapewriting. A touch-sensitive input panel comprises a plurality of keys, where each key in the plurality of keys is representative of a respective plurality of characters. A user can generate a trace over the touch-sensitive input panel, wherein the trace passes over keys desirably selected by the user. A sequence of characters, such as a word, is decoded based upon the trace, and is output to a display or a speaker.

Abstract: A user interface suited for use on mobile devices for entering characters which may require one or more modifiers is disclosed. The interface may be implemented utilizing a touch screen interface on which a user engages the interface, is provided feedback, and removes the user's touch to enter a character. The interface presents a series of main, supplemental and modifier keys. Touching an interface button or main key presents a series of “petals” or supplemental keys emanating from the main key. Each petal or supplemental key may in turn present one or more sub petals or modifier keys emanating from the supplemental key. Each petal or sub-petal may represent another character or a modifier action. The characters and/or actions on the supplemental keys and modifier keys provide options for characters or modifiers which are dependent or related to the main input key.

Abstract: Embodiments provide context-aware inclusion of emoticon item sets in applications and/or services. The emoticon item sets include a plurality of emoticon images or other emoticons. A computing device creates custom emoticon item sets for each of the applications. Based on a determined execution context, the computing device selects the emoticon item set and presents the selected emoticon item set for use within the execution context by a user of the computing device.

Abstract: Disclosed herein are representative embodiments of tools and techniques for providing one or more ink-trace predictions for shape writing. According to one exemplary technique, a portion of a shape-writing shape is received by a touchscreen. Based on the portion of the shape-writing shape, an ink trace is displayed.

Abstract: Techniques are described for automatically determining a touch input mode for a computing device. The computing device can detect whether touch is being performed by a user's finger or by an object. The computing device can then enable a different interaction model depending on whether a finger or an object is detected. For example, the computing device can automatically switch to a finger touch input mode when touch input is detected using the user's finger, and automatically switch to an object touch input mode when touch input is detected using an object. The finger touch input mode can perform user interface manipulation. The object touch input mode can perform input using digital ink. Different feedback models can be provided depending on which touch input mode is currently being used.

Abstract: An adaptive clicker technique is described that provides a standardized polling control and a registration system to support mixed types of clickers and integrate the polling data. One embodiment of the adaptive clicker technique operates as follows. User inputs from more than one type of clicker device (e.g., personal interactive response system device) are received. The inputs from the more than one type of clicker device are formatted with a clicker adapter for each type of clicker to adapt user inputs to a common polling controller. The adapted inputs are then processed with the common polling controller to interface the adapted inputs with a personal response system software application to allow user polling data to be collected and assessed.

Abstract: Techniques are described for automatically performing application-specific actions based on global pre-defined symbols entered using digital ink. For example, a computing device supporting digital ink input can receive digital ink content from a user (e.g., via a digitizer and/or touchscreen), process the digital ink input to recognize text and/or graphical content, determine whether global pre-defined symbols are present in the recognized text and/or graphical content, and perform application-specific actions associated with the global pre-defined symbols that are present. The application-specific actions can be associated with built-in and/or third-party applications.

Abstract: A method, medium, device, and user interface are provided for receiving a handwriting input and for presenting prediction candidates based on the handwriting input. A pen down event is detected in a writing panel of a user interface. The writing panel is expanded to overlie function keys and a candidate window of the user interface such that those features are made inaccessible for inadvertent selections thereof. Upon detection of a pen up event the writing panel is decreased in size to again reveal the features. Recognition candidates are identified based on the handwriting input. Prediction candidates are also identified based on a highest ranking recognition candidate and are presented in combination with the highest ranking recognition candidate. Prediction candidates are thereby identifiable with the recognition candidate with which they are associated and selection of a prediction candidate and recognition candidate may be performed in single selection input.
