Abstract: An electrostatic headphone is provided, comprising a first ear cup assembly, a second ear cup assembly, and a headband assembly coupled to each of the first ear cup assembly and the second ear cup assembly. Each ear cup assembly comprises an electrostatic transducer, a high voltage amplifier electrically coupled to the transducer, and a high voltage power supply electrically coupled to the high voltage amplifier. At least one of the ear cup assemblies further comprises a power source for providing electric power to the high voltage power supply included in the at least one ear cup assembly. In some cases, one or more of the ear cup assemblies further comprises a wireless communication module for receiving audio signals from an audio source.

Abstract: A wearable device, such as an earphone, may include a conductive coil which may be used in several modes, including a first mode for harvesting power for charging an internal battery, a second mode for communicating via near field communications (NFC), and a third mode for communicating via near field magnetic induction (NFMI). Additionally, the wearable device may include a controller, configured to adapt or configure the conductive coil for each of the operational modes.

Abstract: In offline access of data in mobile devices, a request to access a document is received at a mobile server. The document is fetched from a BI platform to the mobile server. Plurality of requests is sent from the mobile server to the BI platform to retrieve data packages from the BI platform. The data packages is converted to a plurality relational database management tables at the mobile server. The plurality of relational database management tables is compressed to a compressed database. The compressed database is sent to the mobile device and stored. A new request is received at the mobile device for operations on the document. Based on the new request, operations are performed on the document based on the compressed database stored in the mobile device, when the mobile device is not connected to the mobile server.

Abstract: A method includes creating multiple logical compartments in a data storage device to hold respective multiple portions of an ordered list of elements, encapsulating each element, of a portion for each compartment, in a node with pointers to successive nodes in the portion, creating a set of references to a first node in each compartment, and providing a count of the number of elements in each compartment.
