Abstract: Various aspects provide an apparatus for sensing a condition or type of a biological tissue. The apparatus comprises a control circuit. The control circuit comprises an electrical connection for delivering electrical signals to the biological tissue. The control circuit is adapted to: deliver an electrical signal to the biological tissue for an active time period; and obtain a charge measurement of an amount of charge stored in the biological tissue in response to the electrical signal during a sampling period after the active time period. Other related apparatuses and systems are also provided.

Abstract: An apparatus and a method are provided for an online jury research system which enables a multiplicity of end-users to build surrogate jury surveys by way of a communications network, such as the Internet. The online jury research system comprises a survey builder which enables the end-users to upload information for which responses of surrogate jurors are desired and to assemble surrogate jury surveys. The uploaded information may include questions, videotaped opening or closing statements, depositions, exhibits, and graphics. A host site is accessible to the end-users by way of the communications network and provides access to a jury services package. In an embodiment, the survey services package comprises services operated by one or more third-party service providers. The online jury research system provides the surrogate jury survey to selected respondents and then compiles the results for review by the end-users.

Abstract: A device for the ionization of gaseous media, comprising a feed channel (101) having a gas feed, a distribution channel (104) having at least one gas outlet, and at least one ionization unit (304), wherein the at least one ionization unit (304) is designed as a connecting channel from the feed channel (101) to the distribution channel (104) and is provided with an electrode (102) and an associated counter electrode (106). The electrode (102) is configured to ionize gas flowing through the ionization unit (304) from the feed channel (101) to the distribution channel (104), wherein the gas flows around the electrode (102), and the at least one gas outlet is designed in the form of one or more nozzles (107) or a plurality of openings (107).

Abstract: Disclosed are devices, systems, and methods for vacuum cleaners, including vacuum cleaners with corner suction functionality. An example vacuum cleaner includes a suction channel assembly that has a main channel including a main suction input and one or more branch channels connected to the main channel and extending away from the main channel, each branch channel having an opening forming an auxiliary suction input. The vacuum cleaner can have a valve positioned between the main channel and at least one branch channel. The valve can be operable to open or close to allow or block suction through the branch channel and/or open or close to allow or block suction through the main channel. The vacuum cleaner can include a lower assembly that carries the suction channel assembly. Each branch channel opens to an exterior of the lower assembly, such as through a front corner of the lower assembly.
