The electrospray ionization process can further involve passing a liquid sample through an axially disposed aperture in a ceramic capillary wire bonding tip in which the terminus of the aperture flares into a bell-shape where the liquid sample exits therefrom. An add-on device can include gel electroelution and separating devices, and a ceramic capillary sample injection tip for carrying out the aforesaid electrospray ionization process. An adjustably mounted cartridge can also be provided with the add-on device for interchangeably receiving the ceramic capillary sample injection tip.

摘要： A gel electroelution device can have a gel spot column having upstream and downstream openings in fluid communication with an inlet and outlet, respectively. The gel spot column receives a gel spot and negative and positive electrodes are fluid communication with the inlet and outlet, respectively. A gel electroelution process can involve flowing a buffer solution through the gel spot in a first direction, and creating an electric field across the gel spot in the same direction. A separator device can have a generally cylindrical collection reservoir in fluid communication with inlet, filtrate, and retentate ports, a filter intermediate the inlet and filtrate ports. The inlet and retentate ports can intersect the collection reservoir in a manner to induce a cyclonic flow. A flow separation process can involve inducing a generally cyclonic flow in the collection reservoir, and filtering the fluid therein to retain the retentate.

摘要： A system and method of applying a permission model to an application operating on a mobile electronic device. When an application is launched on the mobile electronic device, it is determined whether the mobile electronic device possesses execution rights for the application. If the mobile electronic device does not possess valid execution rights for the application, the application is closed. If valid execution rights for the application expire after the application has been launched, a system is provided to inform the user that the rights have expired. The application with expired rights is then closed, unless the user obtains a new and valid rights object for the application.

摘要： A receiver (200) includes a mixing digital-to-analog converter (DAC) (208), a direct digital frequency synthesizer (DDFS), a transimpedance amplifier (TIA) (204) and a first polyphase filter (PPF) (202). The mixing DAC (208) includes a radio frequency (RF) transconductance section for providing an RF current signal responsive to an RF signal and a switching section. The switching section is coupled to the RF transconductance section and includes inputs for receiving bits associated with a digital local oscillator (LO) signal. The switching section is configured to mix the RF current signal with the digital LO signal to provide an analog output signal at outputs of the switching section. The transimpedance amplifier (TIA) (204) includes inputs each coupled to a respective one of the outputs of the switching section and outputs. The first PPF (202) includes inputs each coupled to a respective one the outputs of the TIA (204).

摘要： A MIDlet Suite comprising one or more encrypted installation files is determined at a sending terminal device. A distribution description file comprising Super Distribution identification information for the MIDlet Suite is generated. A non-encrypted distribution archive file comprising the distribution description file and the MIDlet Suite is generated. The distribution archive file is transmitted to a receiving terminal device. The distribution description file is extracted and the extracted distribution description file is parsed in order to obtain the Super Distribution identification information. The MIDlet Suite is extracted from the distribution archive file, and installation information is displayed. Thus the receiving device is able to verify the contents of a received MIDlet Suite before the acquisition of an associated Rights Object, and the user can make a more informed decision whether to acquire the associated Rights Object or not.

摘要： In one form, a reference circuit includes a measurement circuit and a determination circuit. The measurement circuit has an output for providing a ratio of a difference in base-to-emitter voltage (VBE) of a bipolar device at different current densities to a VBE of the bipolar device at a first current density. The determination circuit has an input coupled to the measurement circuit, and an output for providing a digital value of a parameter in response to the ratio. In another form, the reference circuit further includes a voltage generation circuit having an input coupled to the determination circuit, and an output, for modulating an analog voltage using the digital value to provide a reference voltage to the output, wherein the reference voltage is temperature compensated over a temperature range.
