Abstract: Various arrangements for managing which earbud transmits microphone audio are presented herein. A first earbud of a pair of true wireless earbuds may receive a downstream audio packet addressed to a second earbud of the pair of true wireless earbuds. This first earbud can then transmit a negative acknowledgement indicating that the downstream audio packet was not properly received despite the first earbud having properly received the downstream audio packet. With the negative acknowledgment, the first earbud can then transmit an upstream audio packet using an identity of the second earbud.

Abstract: A system and method for detecting donning and doffing of an electronic device includes a capacitive sensor configured to generate a capacitance signal based on a capacitance measured by the sensor. The method also includes generating an average capacitance signal by averaging the capacitance signal over a period of time, and generating an intermediate signal based on a difference between the capacitance signal and the average capacitance signal. The method also includes generating a don or doff signal and setting the average capacitance signal to be equal to the capacitance signal when the don or doff signal is generated. The don signal is generated subsequent to the electronic device changing state from a doffed state to a donned state. The doff signal is generated subsequent to the electronic device changing state from a donned state to a doffed state.

Abstract: A REST application may be explored through discovery of resources and exercising of methods. A user interface displays a graphical representation of the REST application based on a model constructed in memory. User input selects a resource. Methods associated with the selected resource are displayed. A user may select a method and provide input. A request is automatically sent to the server based on the selected method. A representation of the response to the request is displayed on the user interface, allowing the user to further explore the application.

Abstract: According to a technique described herein, a binding document comprises one or more “<bind>” element instances. Each “<bind>” element instance indicates an association between (a) an SVG element instance and (b) a class. When a binding's name is passed to a “createFromTemplate( )” method, the method processes all of the “<bind>” element instances that are associated within that name. For each such “<bind>” element instance, the method (a) creates, in an SVG DOM tree, a clone of a node that corresponds to an SVG element instance indicated in that “<bind>” element instance, (b) instantiates an object that is an instance of a class that is indicated in that “<bind>” element instance, and (c) stores data that establishes a binding between the clone node and the object. Methods of the object can be invoked to affect and/or alter attributes of the clone node to which the object is bound.

Abstract: Systems and methods for reducing the harmonic content of an oscillator are provided. More specifically, waveforms with reduced harmonics are provided, as are waveform generators for producing such waveforms. Such waveform generators can be used in or with a laser driver. However, the present invention is not meant to be limited to use with laser drivers. Rather, embodiments of the present invention are useful anywhere where harmonics resulting from an oscillating waveform need to be reduced.

Abstract: In a method and apparatus for selective convolutional interleaving or de-interleaving of symbols or data bits, a plurality of segments are defined in random access memory, with each segment including a different number of locations for storing symbols. Previously stored symbols are sequentially read out of current locations in the segments respectively, and new symbols are read into the current locations. Next locations in the segments are redesignated as current locations respectively, and the operation is repeated until all of the symbols have been interleaved or de-interleaved. The first location in each segment is designated by a respective segment pointer. The current and next locations are designated as relative offset pointers from the segment pointers, and these locations are incremented by incrementing the offset pointers. Interleaving or de-interleaving operation is determined by the direction in which the segments are sequentially selected for the read/write operations.

Abstract: This dynamic reference potential generating circuit arrangement is especially adaptable to a binary data storage array of the type wherein each data storage cell comprises a single transistor and a single capacitor. A reference potential generating circuit for such an array comprises a pair of such identical transistors connected in parallel and a pair of identical capacitors, connected in common to the transistor emitter electrodes which capacitors couple the emitters to a digit line and to a refresh line, respectively. This arrangement develops a potential swing at the emitter electrodes equal to half of the potential swing that would develop at the emitter electrode of the transistor of a single data storage cell for the same signal swing on the digit line. Basically, the total capacitance connected to the emitter electrode of the generator circuit transistors is twice the capacitance connected to the emitter electrode of the transistor of a single storage cell.
