Abstract: Methods and systems to search a data source based on compatibility with an application. The system receives a first query that includes keywords and identifies at least one keyword in the first query as application information. The application information describes a first application. Next the system infers remaining keywords in the first query as item information that describe a first item that is sought on a network-based marketplace. The first item is a part that is compatible with the first application. Next, the system searches a data storage device to identify a first listing on the data storage device as matched. The first listing includes an item for sale on the network-based marketplace and listing item information that matches the item information in the first query. The first listing further includes listing application information that is matched based on the application information.

Abstract: Systems and methods to configure a query language using an operator dictionary are described. The system receives, from a first user, a search query to search for document information in a database. The system determines that terms of the search query from the first user are in accordance with dictionary information that corresponds to the first user. The dictionary information includes a first list of compatible query operators. The system applies the search query to the index data structure in the database to identify the document information. The system sends an electronic interface to the first user that includes the document information.

Abstract: Wideband capacitive sensing (single-ended or differential) is based on a modulated sense (capacitance) signal. A carrier/drive signal path modulates a reference signal with a carrier signal (such as fixed frequency or spread spectrum) to generate a carrier/drive signal, driven (with optional pre-scaling) out through an output node (to sense capacitor(s)). A sense signal path receives at an input/summing node up-modulated sense capacitance signal(s), corresponding to measured capacitance up-modulated to the carrier frequency, and, after filtering (optional) and amplification, demodulates the up-modulated sense capacitance signal with the carrier signal, to generate a demodulated sense capacitance signal corresponding to measured capacitance, which can be converted to sensor data. Sense signal path amplification can use charge amplification (capacitor feedback), or transimpedance amplification (resistor feedback).

Abstract: Using a processor, receiving, a query including a query image. A database is searched for a set of images similar to the query image, using a two-pass search. The results of the searching are then provided, the results including image members of the set of images similar to the query image. The first pass may be performed using a TF-IDF algorithm and the second pass ranks a predetermined number of results from the first pass by a best match algorithm or other type of algorithm. The type of second pass algorithm may be selectable by a user. If an end signal is not detected, a further two-pass search may be made based on a subsequent query having a subsequent query image. The subsequent query image may be one of the results of the previous two pass search. A subsequent query image may change from an image of a product of a first product category to an image of a product of a second product category.
