Abstract: Provided herein are surfactant compounds that can be used to aid in preparation of protein samples for analysis, for example by mass spectrometry.

Abstract: Contact information may be automatically generated on a device based on an interaction by the user of the device with another individual. A record of the interaction may be obtained by the device and, if it is determined that the interaction satisfies an interaction rule, information from the record of the interaction may be utilized to obtain contact information for the individual. The contact information may be obtained by extracting the contact information directly from the record of the interaction or by extracting an identifier of the individual from the record of the interaction and querying a remote device for the contact information. The obtained contact information may then be stored on the user's device.

Abstract: Dynamic signage systems are provided for a sales environment. A dynamic signage device (e.g., a tablet computer) is associated with a product, e.g., based on a location of the device and/or the product, and can present information about the product to a customer in an interactive manner. The device can automatically check for updated product information and modify its display based on the updated product information. Management of multiple dynamic signage devices can be coordinated within and across stores, and an interactive floor-map creation system incorporating dynamic signage devices can facilitate changing the associations between products and dynamic signage devices.

Abstract: Techniques are provided for designing a circuit that satisfies user-specified functional requirements without the user having to obtain additional education or possess specialized software. According to one embodiment, user-specified functional requirements are received over a network from a client executing a browser. The network may be, for example, the Internet. Based on the user-specified requirements, components and a topology for constructing the circuit are automatically determined. The components determined during this operation have operational values such that, when the components are arranged according to the topology to form the circuit, the circuit satisfies the user-specified functional requirements. One or more web pages that identify the components are then delivered to the browser over the network. According to one aspect of the invention, the component and topology information is used to generate a schematic diagram that is delivered in a web page to the user over the network.
